Christiana Figueres term as the Executive Secretary of the UN Framework Convention on Climate Change (UNFCC) has just ended and we all owe her a huge thank you for the safer climate legacy she has left our children and grandchildren. I've had the pleasure of knowing her for the entire 16 years I've been working on climate change so when she took the job after Copenhagen I knew she was the best person for this difficult position. If anyone could help steer the global community to a stronger international climate agreement I knew Christiana could do it. But could the global community really get its act together and could she successfully navigate this difficult terrain? She helped eliminate any lingering doubts with the Paris Agreement.
While the Paris Agreement wouldn't have occurred without the perseverance of many NGOs, citizens, countries, cities, and companies, it would have failed miserably without Christiana's leadership. She helped rally the world to finalize an historic climate agreement that includes new climate commitments from all major countries and set in motion efforts to require deeper emissions reduction commitments from all countries over time.
Looking back on her tenure there are a couple of traits that she embodied which I think proved critical in getting us to this point. Here are just a few of them.
Smiling. The night the Paris Agreement was agreed by over 190 countries she attended the NGO celebration and she had her trademark smile as she entered the room. I gave her a hug and congratulated her. But she wasn't only smiling after achieving historic agreements since you could often find her with a welcoming grin. I don't know if this was her intention, but I think her smile reminded the negotiators that even in the midst of difficult negotiations they were people trying to secure a better future for their citizens. A smile has a way of setting the tone for difficult negotiations much better than a straight face or a grimace.
Smart. I interacted with Christiana when we were working on similar ideas to help shift developing country action from the project-by-project nature of the Clean Development Mechanism (e.g., individual wind projects) to sector-wide actions that would help transform entire economies, not just little islands of positive climate action in a sea of climate inaction. She was a leading advocate for this changing dynamic when she represented Costa Rica and she helped shepherd through this shift as the Paris Agreement reflects national climate action plans from all major countries.
Persistent. I saw her in the halls of the UN after she had come out of a meeting with NRDC Trustee Robert Redford who called her a "force for nature" after their meeting. That is an appropriate description for Christiana since she kept at it even when the outcome looked in doubt. At that moment a lot of the key details were uncertain as the negotiating text was a mess and important elements around how countries would strengthen their targets over time were in doubt. She had a smile on her face and seemed confident that countries would resolve these difficult issues and move "us from good success in Paris to shining success in Paris". I knew she would do everything in her power to push countries towards that shining success.
Strategic. The UNFCCC Secretariat can't by herself get 194 countries to adopt a strong climate agreement. Reflecting this dynamic Elizabeth Kolbert described Christiana's job as having "the very highest ratio of responsibility (preventing global collapse) to authority (practically none)". In order to overcome this dynamic, Christiana had to be very strategic with how she helped all the key countries get to the strongest agreement possible. She used her giant megaphone to push where she thought public statements could help and she utilized quiet diplomacy where that was a better tactic.
Forward-looking. In order to address climate change, you often have to see at least two steps ahead of the current political dynamic. So you adopt the agreement that is possible today given the current politics, but include key provisions that create the conditions for even greater action in the coming years. Christiana recognized this aspect of international climate agreements as she was a strong champion of including cities, states/provinces, and companies into the global effort. This "action-agenda" can now play a key role in driving greater action so that when countries start to reassess their targets in 2018 they are prepared to outline even deeper targets than they committed to in 2015.
As Christiana leaves her role as Executive Secretary of the UNFCCC she will be missed. She helped shepherd through the historic Paris Agreement and we all owe her a huge debt of gratitude. I suspect that she won't disappear from the international climate radar as solving this issue is too important to her. This passion to address the gravest challenge of our generation runs too deep in her bones for her to go quietly.
Thank you Christiana and keep up the fight!

The Arctic wolf is endangered because of its very fine pelt which is wanted by many hunters. It needs to be saved and put under hunters restriction before it becomes extinct forever.
Industrial development also poses a threat to the wolf, as an increasing number of mines, roads and pipelines encroach on the wolf's territory, and interrupt its food supply.
However, the greatest threat to the Arctic wolf is climate change. Extreme weather variations in recent years have reduced the traditional food supply of the Arctic wolf (populations of muskox and Arctic doesn't find food and decline in numbers).
The Arctic wolf is a sub-species of the grey wolf and lives in the Arctic regions of North America and Greenland.

The Griffon Vulture is a large raptor, inhabitant of the steep cliffs and rocky areas offering numerous cavities where it will nest.
The main cause of the rapid decline in the griffon vulture population is the consumption of poisoned baits set out by people. Wildlife conservation efforts have attempted to increase awareness of the lethal consequences of using illegally poisoned baits through education about the issue. It is very highly vulnerable to the effects of potential wind energy development and electrocution has been identified as a threat.
The flight of the Griffon Vulture is a real show of virtuosity. It soars during long moments, moving scarcely the wings, in an almost unperceivable and measured way.

Soha is the male White Tiger of La Flèche Zoo Park, La Flèche, France
The White Tiger, also known as the White Bengal Tiger, is a pigmentation variant and a subspecies of Tiger, found throughout the Indian subcontinent.
Over the past couple of centuries the White Tiger has become even rarer in the wild due to trophy hunting or capture for the exotic pet trade, with there having been no recorded sightings of these elusive predators for the past 50 years.
Today, the White Tiger can still be found in a handful of zoos and animal sanctuaries around the world with these large and beautiful felines often being the star attraction.
Mohan, the last recorded white tiger born in the wild, was the founding father of the white tigers. He was captured as a cub in 1951 by Maharaja of Rewa. In 1953, Mohan was bred to a normal-coloured wild tigress called Begum "royal consort", which produced orange cubs. Mohan was then bred to his daughter Radha (who carried the white gene inherited from her father) with success.
Mohan was featured in the National Geographic documentary "Great Zoos Of The World" in 1970. He died aged almost 20, and was laid to rest with Hindu rites as the palace staff observed official mourning.

Yuan Zi is the male Giant Panda of Beauval Zoo Park, Saint Aignan sur Cher, France
The giant panda is perhaps the most powerful symbol in the world when it comes to species conservation.
Adored around the world, the distinctive black and white animal is a national treasure in China and has been the symbol of WWF since its formation in 1961.
Giant pandas live in a few mountain ranges in central China, in Sichuan, Shaanxi, and Gansu provinces. They once lived in lowland areas, but farming, forest clearing, and other development now restrict giant pandas to the mountains.
While its numbers are slowly increasing, the giant panda remains one of the rarest and most endangered bears in the world. It is listed as endangered in the World Conservation Union's (IUCN's) Red List of Threatened Species. There are about 1,600 left in the wild. More than 300 pandas live in zoos and breeding centers around the world, mostly in China.

Jabu is the White Lion of La Flèche Zoo Park, La Flèche, France
Up until 2009, when the first white lions was reintroduced to the wild, it was widely believed that the white lion could not survive in the wild. It is for this reason that a large part of the population of white lions now reside in zoos.
The white lions of the Global White Lion Protection Trust (GWLPT) have been reintroduced into their natural habitat and have been hunting and breeding successfully without human intervention for a significant amount of time.
The white lion is a rare color mutation of the Timbavati area. White lions are the same as the tawny African Lion (Panthera leo krugeri) found in some wildlife reserves in South Africa and in zoos around the world.
White lions are not albinos. Their white color is caused by a recessive trait derived from a less-severe mutation in the same gene that causes albinism, distinct from the gene responsible for white tigers. They vary from blonde to near-white. This coloration does not appear to disadvantage their survival.

Liao is the female red panda of Beauval Zoo Park, Saint Aignan sur Cher, France
Red pandas are listed as Endangered on the IUCN Red List. Its population has plausibly declined by 50% over the last three generations (estimated at 18 years) and this decline is projected to continue, and probably intensify, in the next three generations.
The red panda shares the giant panda's rainy, high-altitude forest habitat, but has a wider range. Red pandas live in the cool temperate bamboo forests in Sichuan and Yunnan Provinces in China, in the Himalayas and in Myanmar.
These pandas typically grow to the size of a house cat, though their big, bushy tails add an additional 46 centimeters. The pandas use their ringed tails as wraparound blankets in the chilly mountain heights.
Red pandas are solitary except for breeding season, but in zoos most breeding pairs are housed together year-round for enrichment.

European commissions' opposition to a proposed global ban will spell the beginning of a mass extinction of African elephants, warn officials from 29 African states
Wildlife officials in nearly 30 African states say they are appalled by an EU decision to oppose a comprehensive global ban on the ivory trade.
In a position paper released on 1 July, the European commission said that rather than an all-encompassing ban it would be better to encourage countries with growing elephant numbers to “sustainably manage” their populations.

Conservationists are devastated after the first two chicks born in captivity to one of the world's rarest birds die at a wildfowl centre in Gloucestershire
An attempt to breed one of the world's rarest birds in captivity has failed after the only two chicks which hatched died, conservationists said.
Efforts to breed critically endangered spoon-billed sandpipers, named after their unusual beak, from the world's only captive population seemed to have yielded results, with seven eggs laid and two chicks hatching.

European Medicinal Leech “Hirudo medicinalis.” Sucker is on the right, blood-feeding mouth is on the left. (Encyclopedia of Life image by Pavla Tochorová)
Thanks to a recent reassessment of specimens preserved in jars of alcohol at the Smithsonian's National Museum of Natural History, New Hampshire is now on a short list of states that can claim the New England medicinal leech, Macrobdella sestertia, as a native species. Bright olive green with small reddish-orange spots, scientists discovered three M. sestertia specimens in the museum's collection. Collected in 1936 in Suncoop Pond near Epsom, N.H., they had been mistakenly identified and labeled M. decora (or the North American medicinal leech) some 78 years ago.
Researchers used microscopes to examine the gonads of the specimens, which revealed the leeches had been misidentified. Smithsonian Research Zoologist Anna J. Phillips and Ricardo Salas-Montiel, a master's student at the National Autonomous University of Mexico, made the discovery. Their work was presented recently in the Proceedings of the Biological Society of Washington.
Known only from Maine, Massachusetts and now one New Hampshire pond, M. sestertia is one of the rarest and poorly known leeches in North America. It can grow up to five inches in length and is a Species of Special Concern in the state of Massachusetts.
These three specimens of “M. sestertia” in the collections of the National Museum of Natural History (dorsal, top, and ventral views shown here) were collected in 1936 in New Hampshire and incorrectly identified as a different species.
Medicinal use
Despite being called a medicinal leech, M. sestertia has never been used in medicine, leech expert Phillips points out. It gets the name from its blood-feeding behavior, similar to the European medicinal leech Hirudo medicinalis, which was widely used in medicine in the 1700s and 1800s. “Leeches that feed readily on humans have taken on the name ‘medicinal,' however there are members of these families that don't feed on humans,” Phillips says.
During the 19th century, when bloodletting represented America's premier medical theory, leeches were employed by physicians on a massive scale. This fancy 19th-century display jar from the Smithsonian's National Museum of American History was used by a pharmacist to highlight his supply of medicinal leeches. Elaborate presentation indicates the high value leeches held as a commodity during this time.
Demand for live European medicinal leeches once skyrocketed in Europe and the United States as treatment to drain “bad blood” or to “balance the humors,” then the supposed cause of illness and infirmity. Leeches were attached to a patient's skin to gorge themselves. “Leeches were used as a cure-all for everything from headaches to the common cold,” Phillips says.
Hirudo medicinalis were put to work across Europe and transported in great numbers to the United States and elsewhere, sparing the native U.S. species. “Populations of the European medicinal leech were so overharvested that today it is considered a threatened species by the International Union for Conservation of Nature,” Phillips says. “Today, a different leech species, Hirudo verbana is commercially sold for medicine.” They use in modern medicine is for quite a different purpose.
In 2004, leeches (H. verbana) were approved by the Food and Drug Administration as a “medical device” to prevent post-surgical congestion of the veins. “If you have a skin graft, finger reattachment, or plastic surgery, leeches can be put on the affected area to suck out extra blood that may pool in the tissue causing swelling,” Phillips says. “Anticoagulants in leech saliva enter the bite, go into the wound and keep blood from clotting. In this way leeches increase blood circulation, reduce swelling and promote healing. Leeches have tiny mouths so it is easy to put them on the ends of fingers and noses and ears.”
Hospitals can order leeches sent overnight, starved and ready to feed from a companies like Leeches USA or Biopharm Leeches.
Fine teeth
In the water leeches attach to your skin first using a muscular sucker, similar to a suction cup located on their tail end. Next, they bite with their mouth at the other end using two or three jaws arranged like a Mercedes Benz logo, Phillips says. “The jaws are lined with very fine teeth—up to 150 per jaw—they press the jaws out and move them back and forth slicing the skin and creating the wound. Then they start sucking.”

Only about one-third of leech species have jaws, Phillips adds. “Others have stylets or cutting plates, or have a proboscis for feeding. Almost all medicinal leeches have jaws.”
Blood-feeding Macrobdella can eat between six and 10 times their bodyweight in one meal and take a long time to digest a blood meal. “When I've kept leeches in a lab they only need to eat about 3 or 4 times a year. When they take in a blood meal they need to digest the bits of blood differently. They first eject all the plasma, then process more complex cells such as red and white blood cells,” Phillips says.
“There is little evidence to suggest that leeches transmit disease between humans,” Phillips continues. “It is possible to detect the presence of viruses in the leech gut for several months after they have fed on infected blood, but the viruses do not infect humans during subsequent feedings. Some leeches are vectors for turtle parasites, but these parasites do not pose a threat to humans.”
“The diet of leeches is still something we are exploring. Many leeches are free-living, and we do not know exactly what they feed on,” Phillips says. “Out of more than 680 described leech species, just a handful will feed on humans. Leeches are found in freshwater, terrestrial and marine habitats worldwide except for on Antarctica.”
Frogs, snails, fish
While the diet of the mysterious M. sestertia is unknown, Phillips thinks it could be similar to that of other Macrobdella species: primarily feeding on frogs, but also frog eggs, and perhaps even humans. “Some leeches only feed on insect larvae, some only on snails, still others only fish. Aside from the blood-feeders, there's a whole bunch of leeches that predominantly feed on earthworms,” Phillips says.

No one knows how long Macrobdella species live in the wild, but Phillips estimates three to four years. “Leeches seem to continue to grow as long as they live. Big ones are a target for being eaten by birds, fish and other animals,” Phillips says.
Why does a poorly known leech species living in New England matter? “Because everything is connected,” Phillips explains. “In the wetlands in New England where this leech is found, there are many organisms that contribute to those ecosystems. These ecosystems have complex, interconnected food webs that rely on a diversity of organisms. All ecosystems are like a machine; to function correctly it must have all its parts in order to work.”
“For example,” Phillips continues, “leeches may be one of many invertebrates a bird eats. If there is a decline in aquatic insect larvae in a given year, the leeches may not be affected and the bird might not go hungry that year because it could eat more leeches. Having a diversity of organisms in an ecosystem helps it to maintain integrity and survive environmental disturbances, such as a flood, a drought or changing climates.”
Macrobdella sestertia has been found only a handful of times and has not been seen in the wild since 1997, Phillips adds. “The big question when you have a poorly-known species like M. sestertia is not necessarily that they have declined, it is more likely that no one is looking. This species may have a much broader distribution than what we know, but the right people have not seen the specimens. The danger right now for many animals including leeches is that if their habitat is being lost due to residential or commercial development of lands, then we may not even know that we are contributing to, if not the driver of, its decline.”

Radio astronomers have used a radio telescope network the size of the Earth to zoom in on a unique phenomenon in a distant galaxy: a jet activated by a star being consumed by a supermassive black hole as seen in center of galaxy Messier 106 above. The record-sharp observations reveal a compact and surprisingly slowly moving source of radio waves, with details published in a paper in the journal Monthly Notices of the Royal Astronomical Society.
The artist's impression below shows the remains of a star that came too close to a supermassive black hole. Extremely sharp observations of the event Swift J1644+57 with the radio telescope network EVN (European VLBI Network) have revealed a remarkably compact jet, shown here in yellow.
The international team, led by Jun Yang (Onsala Space Observatory, Chalmers University of Technology, Sweden), studied the new-born jet in a source known as Swift J1644+57 with the European VLBI Network (EVN), an Earth-size radio telescope array.
When a star moves close to a supermassive black hole it can be disrupted violently. About half of the gas in the star is drawn towards the black hole and forms a disc around it. During this process, large amounts of gravitational energy are converted into electromagnetic radiation, creating a bright source visible at many different wavelengths.
One dramatic consequence is that some of the star's material, stripped from the star and collected around the black hole, can be ejected in extremely narrow beams of particles at speeds approaching the speed of light. These so-called relativistic jets produce strong emission at radio wavelengths.
The first known tidal disruption event that formed a relativistic jet was discovered in 2011 by the NASA satellite Swift. Initially identified by a bright flare in X-rays, the event was given the name Swift J1644+57. The source was traced to a distant galaxy, so far away that its light took around 3.9 billion years to reach Earth.
Jun Yang and his colleagues used the technique of very long baseline interferometry (VLBI), where a network of detectors separated by thousands of kilometres are combined into a single observatory, to make extremely high-precision measurements of the jet from Swift J1644+57.
Three years of extremely precise EVN measurements of the jet from Swift J1644+5734 show a very compact source with no signs of motion.

"Using the EVN telescope network we were able to measure the jet's position to a precision of 10 microarcseconds. That corresponds to the angular extent of a 2-Euro coin on the Moon as seen from Earth. These are some of the sharpest measurements ever made by radio telescopes", says Jun Yang.
Thanks to the amazing precision possible with the network of radio telescopes, the scientists were able to search for signs of motion in the jet, despite its huge distance.
"We looked for motion close to the light speed in the jet, so-called superluminal motion. Over our three years of observations such movement should have been clearly detectable. But our images reveal instead very compact and steady emission - there is no apparent motion", continues Jun Yang.
The results give important insights into what happens when a star is destroyed by a supermassive black hole, but also how newly launched jets behave in a pristine environment. Zsolt Paragi, Head of User Support at the Joint Institute for VLBI ERIC (JIVE) in Dwingeloo, Netherlands, and member of the team, explains why the jet appears to be so compact and stationary.
"Newly formed relativistic ejecta decelerate quickly as they interact with the interstellar medium in the galaxy. Besides, earlier studies suggest we may be seeing the jet at a very small angle. That could contribute to the apparent compactness", he says.
The record-sharp and extremely sensitive observations would not have been possible without the full power of the many radio telescopes of different sizes which together make up the EVN, explains Tao An from the Shanghai Astronomical Observatory, P.R. China.
"While the largest radio telescopes in the network contribute to the great sensitivity, the larger field of view provided by telescopes like the 25-m radio telescopes in Sheshan and Nanshan (China), and in Onsala (Sweden) played a crucial role in the investigation, allowing us to simultaneously observe Swift J1644+57 and a faint reference source," he says.
Swift J1644+57 is one of the first tidal disruption events to be studied in detail, and it won't be the last.
"Observations with the next generation of radio telescopes will tell us more about what actually happens when a star is eaten by a black hole - and how powerful jets form and evolve right next to black holes", explains Stefanie Komossa, astronomer at the Max Planck Institute for Radio Astronomy in Bonn, Germany.
"In the future, new, giant radio telescopes like FAST (Five hundred meter Aperture Spherical Telescope) and SKA (Square Kilometre Array) will allow us to make even more detailed observations of these extreme and exciting events," concludes Jun Yang.

An open letter a "manifesto" of sorts, framed and singed by many of the great scientists and minds of our century --from Stephen Hawking to Frank Drake, Lord Martin Rees, to Caltech's Kip Thorne shown above-- was published this past April 2016 (and posted below), outlining the philosophical foundations that inspired the Breakthrough Starshot project and the search for the answer to the seminal question of the 21st Century: "Are we alone in the universe?"
As all the world knows by now, Yuri Milner, the Russian billionaire Internet investor, and Stephen Hawking, the famed astrophysicist, have revealed plans for an interstellar mission, $100 million Breakthrough Starshot, that would launch chip-sized robotic probes at more than 25 percent the speed of light for 20-year journeys on the 25-trillion mile trip our nearest star system, Alpha Centauri.
A huge ground-based laser will push the swarms of "laser sails" (up to tens of thousands of probes per year) propelled by light from the sun toward their exotic destination. Light exerts very little pressure, but prior projects have already successfully tested a number of solar sails — spacecraft propelled by light from the sun. As a prelude to the journey, Starshot could launch interplanetary missions to explore unsolved mysteries of our solar system — driving "space-chips" to Mars in roughly 30 minutes, or to the potential life bearing habitats of Enceladus, Titan, and Europa.
Scientists estimate the orange dwarf Alpha Centauri B system is slightly older than our 4.6-billion-year old solar system at anywhere from 4.8 billion to 6.5 billion years old. If life on a planet or moon in the habitable zone of Alpha Centauri B evolved similarly as it did on Earth, then primitive forms of life could already have flourished there when the young Earth collided with a Mars-sized object, forming our moon.
Jonathan McDowell from the Harvard-Smithsonian Center for Astrophysics said that Starshot is humanity's best chance of reaching Alpha Centauri, but has several hurdles to surmount. "The trick is accelerating with the pressure of light to accelerate a big, thin film of plastic that's shiny and catches the laser light so it goes faster," he said. "That's been demonstrated by the Japanese in interplanetary space a couple of years ago, but no one's got it really fast and we're talking about putting something a thousand times faster than any human artifact has ever done." McDowell said that it could take a decade to get a spacecraft to accelerate with a light sail, and longer to adapt the technology for the Starshot nanocraft. "I think 10 years to get to demonstrating something accelerated with a laser light sail, but a generation to be able to do it for real to Alpha Centauri."
Harvard physics professor Abraham Loeb said that the Starshot project is made possible by recent advances in the miniaturization of electronics: "This method we're talking about was conceived as soon as the laser was invented … The problem back then was that people thought that they needed to take humans along," he explained. "The big technological advance over the past decades has been the miniaturization of electronics, smart electronics. It was all driven by the cellphone industry. If you look at an iPhone and strip it from the case and the human interface, you're left with smart electronics that weigh roughly a gram, much lighter than anything else to use."
Loeb said that Starshot will be able to rapidly explore the Solar System. "Just to give you an example, to get to Pluto it would take three days instead of the 9½ years it took New Horizons to get there. If we launch at a fifth of the speed of light, it'll get there the same week," he said.
The seminal "Open Letter," the Alpha Centauri Manifesto, below, lays down the foundational thinking behind the Breakthrough project.
The story of humanity is a story of great leaps out of Africa, across oceans, to the skies and into space. Since Apollo 11's ‘moonshot', we have been sending our machines ahead of us to planets, comets, even interstellar space. A mature civilization, like a mature individual, must ask itself this question. Is humanity defined by its divisions, its problems, its passing needs and trends? Or do we have a shared face, turned outward to the Universe?
In 1990, Voyager 1 swiveled its camera and captured the ‘Pale Blue Dot' - an image of Earth from six billion kilometers away. It was a mirror held up to our planet - home of water, life, and minds. A reminder that we share something precious and rare. But how rare, exactly? The only life? The only minds?
For the last half-century, small groups of scientists have listened valiantly for signs of life in the vast silence. But for government, academia, and industry, cosmic questions are astronomically far down the list of priorities. And that lengthens the odds of finding answers. It is hard enough to comb the Universe from the edge of the Milky Way; harder still from the edge of the public consciousness.
Image3
Yet millions are inspired by these ideas, whether they meet them in science or science fiction. Because the biggest questions of our existence are at stake. Are we the Universe's only child - our thoughts its only thoughts? Or do we have cosmic siblings - an interstellar family of intelligence? As Arthur C. Clarke said, “In either case the idea is quite staggering.”
That means the search for life is the ultimate ‘win-win' endeavor. All we have to do is take part. Today we have search tools far surpassing those of previous generations. Telescopes can pick out planets across thousands of light years. The magic of Moore's law lets our computers sift data orders of magnitude faster than older mainframes - and ever quicker each year.
These tools are now reaping a harvest of discoveries. In the last few years, astronomers and the Kepler Mission have discovered thousands of planets beyond our solar system. It now appears that most stars host a planetary system. Many of them have a planet similar in size to our own, basking in the ‘habitable zone' where the temperature permits liquid water. There are likely billions of earth-like worlds in our galaxy alone. And with instruments now or soon available, we have a chance of finding out if any of these planets are true Pale Blue Dots home to water, life, even minds.
There has never been a better moment for a large-scale international effort to find life in the Universe. As a civilization, we owe it to ourselves to commit time, resources, and passion to this quest.
But as well as a call to action, this is a call to thought. When we find the nearest exo-Earth, should we send a probe? Do we try to make contact with advanced civilizations? Who decides? Individuals, institutions, corporations, or states? Or can we as species - as a planet - think together?
Three years ago, Voyager 1 broke the sun's embrace and entered interstellar space. The 20th century will be remembered for our travels within the solar system. With cooperation and commitment, the present century will be the time when we graduate to the galactic scale, seek other forms of life, and so know more deeply who we are.
But with current rocket propulsion technology, it would take tens or hundreds of millennia to reach our neighboring star system, Alpha Centauri. The stars, it seems, have set strict bounds on human destiny. Until now. In the last decade and a half, rapid technological advances have opened up the possibility of light-powered space travel at a significant fraction of light speed. This involves a ground-based light beamer pushing ultra-light nanocrafts miniature space probes attached to lightsails to speeds of up to 100 million miles an hour. Such a system would allow a flyby mission to reach Alpha Centauri in just over 20 years from launch, and beam home images of possible planets, as well as other scientific data such as analysis of magnetic fields.
Breakthrough Starshot aims to demonstrate proof of concept for ultra-fast light-driven nanocrafts, and lay the foundations for a first launch to Alpha Centauri within the next generation. Along the way, the project could generate important supplementary benefits to astronomy, including solar system exploration and detection of Earth-crossing asteroids.

January 2016 also saw ‘first light' for Breakthrough Listen, with observations marking the start of the 10-year effort announced in July 2015 at London's Royal Society by Yuri Milner, Stephen Hawking, Lord Martin Rees, Ann Druyan, and Frank Drake. Hundreds of hours of observations have taken place using the Green Bank Radio Telescope in West Virginia and Lick Observatory's Automated Planet Finder in Mt. Hamilton, California.
Breakthrough Listen is the largest ever scientific research program aimed at finding evidence of civilizations beyond Earth. The scope and power of the search are on an unprecedented scale: The program includes a survey of the 1,000,000 closest stars to Earth. It scans the center of our galaxy and the entire galactic plane. Beyond the Milky Way, it listens for messages from the 100 closest galaxies to ours.
The instruments used are among the world's most powerful. They are 50 times more sensitive than existing telescopes dedicated to the search for intelligence.
The radio surveys cover 10 times more of the sky than previous programs. They also cover at least 5 times more of the radio spectrum and do it 100 times faster. They are sensitive enough to hear a common aircraft radar transmitting to us from any of the 1000 nearest stars.
They are also carrying out the deepest and broadest ever search for optical laser transmissions. These spectroscopic searches are 1000 times more effective at finding laser signals than ordinary visible light surveys. They could detect a 100 watt laser (the energy of a normal household bulb) from 25 trillion miles away.
Breakthrough Listen is releasing the first batch of data for public access at the Breakthrough Initiatives website. Data from the Green Bank Telescope is also available to users of UC Berkeley's SETI@home software.
Observations made so far by Breakthrough Listen include most of the stars within 16 light years of Earth (including stars such as 51 Pegasi that are known to host extra-solar planets), and a sample of stars between 16 and 160 light years away. This included nearby sun-like and giant stars as well as numerous binary stars. The search also targeted around 40 of the nearest spiral galaxies, including members of the Maffei Group in the direction of the constellation Cassiopeia. Stars within 16 light years accessible only from the Southern Hemisphere, such as Alpha Centauri, will be observed by the end of the year with the Parkes Telescope.
This year's Observation Plan for all three telescopes has been published and can be found at breakthroughinitiatives.org/OpenDataSearch

"This is just the tip of the iceberg," says Andrew Glikson from The Australian National University (ANU). "We've only found evidence for 17 impacts older than 2.5 billion years, but there could have been hundreds. Asteroid strikes this big result in major tectonic shifts and extensive magma flows. They could have significantly affected the way the Earth evolved."
This May, 2016, scientists have found evidence of a huge asteroid 20 to 30 kilometers across that struck the what is today Australia, creating a 400 kilometer-wide impact zone after breaking in two moments before it slammed into the Earth. The impact crater has long since disappeared. But a team of Aussie geophysicists has found the twin scars of the impacts the largest impact zone ever found on Earth hidden deep in the earth's crust.
Tiny glass beads called spherules, found in north-western Australia were formed from vaporized material from the asteroid impact, said Glikson. “Large impacts like these may have had a far more significant role in the Earth's evolution than previously thought,” Glikson said.
The exact date of the impacts remains unclear. The surrounding rocks are 300 to 600 million years old, but evidence of the type left by other meteorite strikes is lacking. “It's a mystery we can't find an extinction event that matches these collisions. I have a suspicion the impact could be older than 300 million years,” he added.
“There are two huge deep domes in the crust, formed by the Earth's crust rebounding after the huge impacts, and bringing up rock from the mantle below,” Glikson said. The two impact zones total more than 400 kilometres across, in the Warburton Basin in Central Australia. They extend through the Earth's crust, which is about 30 kilometres thick in this area.
"The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes, it would have caused huge tsunamis and would have made cliffs crumble," said Glikson, from the ANU Planetary Institute. "Material from the impact would have spread worldwide. These spherules were found in sea floor sediments that date from 3.46 billion years ago."
About 3.8 to 3.9 billion years ago the moon was struck by numerous asteroids, which formed the craters, called mare, that are still visible from Earth "Exactly where this asteroid struck the earth remains a mystery," Glikson said. "Any craters from this time on Earth's surface have been obliterated by volcanic activity and tectonic movements."
Glikson and Arthur Hickman from Geological Survey of Western Australia found the glass beads in a drill core from Marble Bar, in north-western Australia, in some of the oldest known sediments on Earth. The sediment layer, which was originally on the ocean floor, was preserved between two volcanic layers, which enabled very precise dating of its origin.
Glikson has been searching for evidence of ancient impacts for more than 20 years and immediately suspected the glass beads originated from an asteroid strike. Subsequent testing found the levels of elements such as platinum, nickel and chromium matched those in asteroids. There may have been many more similar impacts, for which the evidence has not been found, said Glikson.

Jupiter watchers have long known that the giant planet's ever-present polar auroras thousands of times brighter and many times bigger than Earth are powered by both electrically charged particles from the Sun colliding with Jupiter's magnetic field and a separate interaction between Jupiter and one of its many moons, called Io. But there are also auroral explosions on Jupiter, or periods of dazzling brightening, similar to auroral storms on Earth, that no one could definitively trace back to either of those known causes.
In the aurora-making interaction of Jupiter and Io, volcanoes on the small moon blast clouds of electrically charged atoms (ions) and electrons into a region surrounding Jupiter that's permeated by the planet's powerful magnetic field, thousands of times stronger than Earth's. Rotating along with its rapidly spinning planet, the magnetic field drags the material from Io around with it, causing strong electric fields at Jupiter's poles. The acceleration of the ions and electrons produce intense auroras that shine in almost all parts of the electromagnetic spectrum but most brightly in high-energy bands, like ultraviolet light and X-rays, that are invisible to unaided human eyes.
Io is the only known place in the Solar System with volcanoes erupting extremely hot lava like that seen on Earth. Because of Io's low gravity, large volcanic eruptions produce an umbrella of debris that rises high into space. Such outbursts can send material hundreds of miles above the surface.
The recent eruptions resemble past events that spewed tens of cubic miles of lava over hundreds of square miles in a short period of time. All three events, including the largest, most powerful eruption of the trio on 29 August, 2013, were likely characterized by “curtains of fire," as lava blasted out of fissures perhaps several miles long.
The 29 August, 2013, outburst on Io shown below was among the largest ever observed on the most volcanically active body in the solar system. Infrared image taken by Gemini North telescope. Image credit: Katherine de Kleer, UC Berkeley.
The brightest eruption at a caldera named Rarog Patera, was calculated to have produced a 50 square-mile, 30ft thick lava flow, while another close to a caldera called Heno Patera, produced flows covering 120 square miles. Both were located in Io's southern hemisphere, near its limb, and were nearly gone when imaged five days later.
Now, new observations of the planet's extreme ultraviolet emissions show that bright explosions of Jupiter's aurora likely also get kicked off by the planet-moon interaction, not by solar activity. A new scientific paper about these observations by Tomoki Kimura of the Japan Aerospace Exploration Agency (JAXA), in Sagamihara, Kanagawa, Japan, and his colleagues, was published online today in Geophysical Research Letters, a journal of the American Geophysical Union.
Io produces about 100 times more lava each year than all the volcanoes on Earth. While Earth's volcanoes occur in localized hotspots like the "Ring of Fire" around the Pacific Ocean, Io's volcanoes are distributed all over its surface. A global magma ocean about 30 to 50 kilometers (20 to 30 miles) beneath Io's crust helps explain the moon's activity.
"It has been suggested that both the Earth and its moon may have had similar magma oceans billions of years ago at the time of their formation, but they have long since cooled," said Torrence Johnson, a former Galileo project scientist based at NASA's Jet Propulsion Laboratory in Pasadena, Calif. He was not directly involved in the study. "Io's volcanism informs us how volcanoes work and provides a window in time to styles of volcanic activity that may have occurred on the Earth and moon during their earliest history."
NASA's Voyager spacecraft discovered Io's volcanoes in 1979, making that moon the only body in the solar system other than Earth known to have active magma volcanoes. The energy for the volcanic activity comes from the squeezing and stretching of the moon by Jupiter's gravity as Io orbits the largest planet in the solar system.
Starting in January 2014, a telescope aboard the JAXA's Hisaki satellite, which focused on Jupiter for two months, recorded intermittent brightening of the giant planet's aurora. The telescope detected sudden flare-ups on days when the usual flow of charged particles from the Sun, known as the solar wind, was relatively weak.
Additional space and ground-based telescopes, including the Hubble Space Telescope, also viewed Jupiter during these lulls in the solar wind. Both Hisaki and Hubble witnessed explosions of the planet's aurora despite the solar wind's calm, suggesting that it's the Jupiter-Io interaction driving these explosions, not charged particles from the Sun, according to the new study. The new research does not address exactly what is happening in the Jovian magnetosphere to cause the temporary brightening of auroral explosions.

Now the largest exhibit in the Imperial War Museum's collection, HMS Belfast is permanently moored on the River Thames in the Pool of London. She is seen here from outside Old Billingsgate Market on the river's north bank as a bright autumnal day comes to a close.
The Town-class cruisers (Belfast and Edinburgh) were constrained to less than 10,000 tons by the Washington Naval Treaty of the early 1920s. The original design included quadruple 6-inch gun mountings, but due to problems with construction, improved versions of the triple mountings fitted to the earlier ships of the class were fitted instead. These were lighter than those planned, and the weight saved was used to improve the ship's armour and anti-aircraft defences.
Belfast was launched on St Patrick's Day in 1938 at Harland and Wolff Shipyard in Belfast and was commissioned in August 1939. At around 0100 on 21 November 1939 she was seriously damaged leaving the Firth of Forth by a magnetic mine laid on 4 November by the German submarine U-21. The mine broke the keel and wrecked the hull and machinery to such an extent that she only returned to service in the Home Fleet in November 1942. Improvements had been made to the ship during repairs, notably bulged amidships to improve her longitudinal strength and stability, and fitting the latest radar and fire control; her displacement had risen from 11,175 to 11,553 tons, making her Britain's heaviest cruiser.
On 26 December 1943, in what became the Battle of North Cape, Norfolk, Belfast and Sheffield encountered the German battlecruiser Scharnhorst, and, with the battleship HMS Duke of York, sank her. In June 1944, Belfast took part in the D-Day bombardment in support of landings on Gold and Juno beaches. Belfast was almost continuously in action for the next five weeks, firing thousands of rounds from her 6 and 4inch batteries in support of troops until the battlefront moved out of range inland. Her final salvo in the European war was fired on 8 July during Operation Charnwood, the battle to capture Caen, when she engaged German positions together with the battleship HMS Rodney and the monitor HMS Roberts.
Belfast served in the Korean War, supporting UN forces by naval bombardment. In July 1952 she was hit by a Communist battery, losing one man killed and four wounded. Belfast was modernised between January 1956 and May 1959. In December 1961 she provided the British guard of honour at Dar-es-Salaam during the Tanganyika independence ceremony. The ship was finally paid off on 24 August 1963.

The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study. The study offers evidence that the negative phase of the Interdecadal Pacific Oscillation, which is characterized by cooler-than-average sea surface temperatures in the tropical eastern Pacific, has created favorable conditions for additional Antarctic sea ice growth since 2000.

Few things can ruin a good run like turning a corner and facing a towering hill. You were making good time! You were flying along and everything felt great and the robot lady on your running app was whispering excellent numbers into your ear. Now that all comes to an end. You must trudge.
Hills are as much a mental challenge as a physical one. If you fear hills, it's hard to get better at running them. Maybe you can't turn off gravity, but you can change the way you think.
This is an especially important point in races, and anytime you're running with other people. No matter how much you slow down, remember that everyone else is slowing down too. Even the people that have their heads high and look like they're breathing easy. Those people know how to run hills (and soon you will, too) but gravity applies to them just as it does to you. They are fighting to chug up the hill. They are much slower, now, than they were on the flat a few minutes ago. That's normal.
So don't be discouraged that you, too, slow down when you hit a hill. Just like the speedsters are faster than you on the flat, some people will be faster than you on a hill. When people start passing you, you can't wish yourself stronger. All you can do is use the strength that you have today, however much or how little that might be.
We've explained hill running techniques before, but one part is crucial: you can't let yourself work harder on the hill than on flat ground. Does that sound impossible? Remember, you're slower on the hills. You know this, so you're allowing yourself to go slow. Even embarassingly slow. (But now that you understand this, you won't be embarrassed.) You must go so slow that the hill no longer feels difficult.
http://vitals.lifehacker.com/how-to-run-hil...
The easiest way to do this is to listen to the rhythm of your footsteps. When the road starts to slope upwards, keep that rhythm the same, but make your strides smaller. It may feel like you're only moving by an inch with each step. That's okay. You're still moving.
It only takes about ten seconds to gauge whether your steps are small enough. If you're out of breath, try again: step even smaller. You need to find the place where you're not working any harder than you would be on flat ground.
What if you're stepping so small that it would be faster to just walk? There are two answers to this. If you're in a race, do whatever is faster for the same effort. On very steep hills, that might be walking. But if you're on a training run where pace isn't super important, practice running even if you're slow. That will build the right muscles so someday soon you will be able to run faster.
If you end up walking because you started up the hill too fast, that's okay. Walking does not mean giving up. Keep up the same effort level as when you were jogging on the flat. Stay strong. Keep climbing.
Now that you're locked in to the perfect pace, do not look up. Hold your head high, because that's good running form, but don't pay attention to the top of the hill. There are two reasons for this.
First, the top of the hill is an illusion. If you pick a spot that looks like the top, and decide your effort will be over when you reach that spot, you'll find when you arrive that you are not at the top after all.
Second, this isn't a sprint with a finish line. You chose a pace that feels easy, so you shouldn't be longing for the stretch to end. I once tried to explain this to my son in terms of the fable about the tortoise and the hare. You don't want to sprint like the hare, because you'll get tired, I said. But before I could blurt out some advice about going “slow,” he explained it better than I could. “OK, not rabbit fast,” he said. “I'll go turtle fast.”
You can go turtle fast forever. It doesn't matter how far away the top of the hill is. It could be ten paces, it could be ten miles. You're going, and that's all that counts. Don't look up.
When you tell yourself that you're good at hills, it becomes true. Skeptical? Go out and run a small hill this week. Use these techniques and try to make your climb feel easy and great. Now, stick that happy easy hill run into your mental highlight reel. The next time you hit a monster hill, smile. You know hills. You're good at hills. You've got this.
http://vitals.lifehacker.com/make-a-mental-...
Even with that minimal preparation, you have a real advantage over the hill-phobes: confidence. They fear the hill and stop, walk, feel defeated, feel that they failed. You hit the same hill and slow down, but you are in your element. You are not afraid to keep moving. You respect the hill, but you conquer it.

Harvesting the eggs, sperm and tissue of endangered animals for future cloning is a good plot for a horror film, but not reality (Report, 5 July). We need to spend time and resources on saving existing animals whose natural habitats are fast disappearing, rather than trying to resurrect them. Cloning animals after they've vanished from nature is fraught with problems, such as severe birth defects, premature degenerative diseases and poor immunity. If wild animals were cloned, they would likely end up in zoos, denied the opportunity to do almost anything natural and enjoyable, just like the polar bears, elephants and other animals currently kept captive. It is inarguably urgent to save threatened species' habitats, but inflicting pain and torture is not the answer. If Dolly has taught us one thing, it's that cloning animals belongs only in sci-fi stories.

The Islamic holy month of Ramadan is a time of reflection and prayer. Muslims refrain from eating, drinking, smoking, and sex during the daylight hours in order to focus on spirituality, good deeds, and charity. When the sun sets, communities come together for Iftar, the breaking of the fast. Now that the month has come to a close, Eid al-Fitr, or the festival of the breaking of the fast, begins. We looked at Ramadan earlier this month, but there were just so many more great photographs, we're doing it again.

Oystermouthcastle, castle / swansea / wales / united kingdom
The early castle[edit]
The first castle was founded by William de Londres of Ogmore Castle soon after 1106 following the capture of Gower by the Normans. In 1116 the Welsh of Deheubarth retook the Gower Peninsula and forced William to flee his castle which was put to the torch. The castle was rebuilt soon afterwards, but was probably destroyed again in 1137 when Gower was once more retaken by the princes of Deheubarth. The Londres or London family finally died out in 1215 when Gower was again taken by the Welsh under the leadership of Llywelyn the Great. In 1220 the Welsh were expelled from the peninsula and the government of Henry III of England returned the barony of Gower to John de Braose who rebuilt both Swansea Castle and Oystermouth.
The Horniman's Festival of Brasil is a cocktail of culture, costumes and chaos and carnival spirit is just what we need this British so-called summertime
How could I stop thinking about Britain's misery? There I was, in a sunny south London park on a Sunday afternoon, dully reading political news on my phone, when I was persuaded to put on a cow mask and skirt and join in a carnival. Crisis? What crisis? It was time to parade and dance.
Led by a mirror-shaded policeman riding a hobbyhorse and seduced by trumpeters and drummers, a crowd of dazed Brits embraced a Brazilian festive fever. We became a small part of Rio de Janeiro. As the carnival director told us, the point was not to show off our costumes but to go wild and enjoy ourselves without inhibitions, by dancing to that infectious beat, throwing ourselves to the ground, forming human tunnels. And doing a hokey cokey in which everyone near me shouted “In”'. (Turns out, you can't escape the aftermath of the EU referendum.)

Coca Cola Zero Sugar has been re-launched in the UK, backed by a £10 million ad campaign, a new name and new design.
Formerly Coke Zero, the renamed drink fits in with other products in the Coke family as part of it's “one brand” strategy, as we found out from vice president of global design at Coca-Cola James Somerville in April. You can read the full story here.
The new Coca Cola Zero Sugar design, which features a red disk was unveiled in April but only rolls out to the UK market now. It carries the strapline “Taste's more like Coke, looks more like Coke”.
The new campaign and the positioning are part of Coca Cola's drive to encourage consumers to cut down the amount of sugar they consume.
Coke Zero's last overhaul was in 2014, which was designed by Bulletproof and positioned around a “Just add Zero” campaign.

It's been a tough year for charities. According to a report by the Charity Commission, their reputation has collapsed. We're uncomfortable with their aggressive fundraising, we distrust how they spend our money and we have doubts about the difference they make to the causes we support.
Design can't change the way charities behave. But the connections they make with us are what creates trust, so their need to communicate well is greater now than ever.
It's been decades since charities first latched onto the importance of identity so why does the sector still look like a design scrapyard? Why is it awash with clichés and me-too design? What's with all the corny people icons, fake kid's drawings, and vacuous, clipart-like symbols? Why are so many charity identities mind-numbingly ordinary if not downright garbage?
A shortage of half-sensible budgets is one reason. But there's more to it than that. Charities do themselves all sorts of disfavours. They like jumping on bandwagons. They're inclined to imitate rather than embrace ideas that are individual to them. And they want to be loved by everyone, which can make impossible demands on their communications.
What's more, charities can be exasperating to deal with because of their governance and the “democratic” way they're managed. Trustees usually have the final say on a new identity, but they generally know little or nothing about communications so their opinions can be irritatingly subjective.
So here's how to survive in the curious world of charity identity and how to go about conjuring up work that invites people in and makes them want to know more.
Stop peddling snake oil
You know who you are. You use words like differentiation, touchpoints, behaviours and learnings. Time and again, gibberish is passed off as “brand insight” and the upshot is work that's not what it's cracked up to be. Quit trying to bamboozle people and do your job properly. If you expect charities to behave with honesty, integrity and straightforwardness, you should too.
Listen
Listening is the most important thing designers do. Everyone's got stories to tell so listen to trustees, listen to management, listen to staff and listen to volunteers. You only learn things when you listen.
Have an opinion
In the creativity game, you're not a player unless you've got an opinion. Be single-minded. Don't waste time trying to please everyone. Be crystal-clear about what you need to do and get on with it. One bloody good idea is all it takes.
Trust your intuition
Charities are increasingly risk-averse. Consultation and research are used to lessen the risk of failure rather than boost the chance of success. Design should be about the sheer joy and excitement of doing things that haven't been done before. So if you want your work to be truly unforgettable, you've got to be daring and you've got to trust your intuition it's always right.
Don't take no for an answer
Intelligent, idiosyncratic identities can be hard to sell because they drag people into their discomfort zone. Charities are inclined to resist ideas that rock the boat, so design that's never going to get noticed usually wins the day. Don't let it happen. Gutsy, ballsy, feisty ideas are what charities really need and it's up to you to make sure that's what they get.
Idiosyncratic + ruthless = unforgettable
I've said it before and I'll say it again, this is my formula for an unforgettable identity. It has to be idiosyncratic; that's to say, everything an organisation says and does and the way it looks should be so individual and characteristically ‘them' that they just couldn't be mistaken for any other. It's those idiosyncrasies that need to be uncovered, given form and voice, and ruthlessly protected.

Technology brand Dyson will open its first ever permanent London store this week, which will allow people to try out products first-hand and learn about the science behind them.
The Dyson Demo is based on Oxford Street, and showcases the company's portfolio of products including its regular, cordless and autonomous vacuum cleaners, purifier fans, LED lighting and the recently launched Supersonic hairdryer.
Dyson Demo has been designed by Dyson in partnership with WilkinsonEyre, the architectural practice which also recreated the brand's headquarters and factory in Malmesbury, Wiltshire in a £250 million project in 2014.
The space is spread over two floors the ground floor features white plinths presenting the portfolio of products, including the Dyson Pure Cool Link purifier fan, the Dyson 360 Eye robot (robot vacuum cleaner), Supersonic hairdryer, and the Cu-Beam lighting range.
The walls are also adorned with copies of the V8 cord-free vacuum, alongside pots containing different types of dust, food and debris. Visitors are then invited to test the vacuum cleaner on four different floor surfaces, with the dirt of their choice.
A glass staircase designed by WilkinsonEyre leads to the first floor, which includes hair salon stations where visitors can have their hair styled with the Supersonic hairdryer. The area also includes moving, mechanical installations which demonstrate the product testing phase of the hairdryer on real samples of human hair.
Dyson “experts”, who work alongside engineers at the headquarters in Malmesbury, will also be stationed around the store at all times for visitors to speak to about the science behind the products.
Tom Mogridge, a Dyson senior design engineer, says that these “experts” “understand how the engineers think” and have “good insight into the company's products”. “It's really exciting that a product that I've worked on is able to be demonstrated for visitors in store,” he says.
The space also includes digital screens used across walls, which show the products in action.
There are no tills, but visitors are able to buy products in-store once they have spoken to somebody and tested out a product.
Jake Dyson, research, design and development director, and the son of company founder James Dyson, says: “The Dyson Demo encourages people to be hands-on. It's all about showing the inner workings of products it's really important to demonstrate them first hand so people understand the engineering behind them.”
Max Conze, chief executive officer at Dyson, adds that the space will help to educate visitors about the “fundamentally different ways” that Dyson technology works, and will “bring engineering to life”.
The space will also be used for engineering workshops for school children during holidays, hosted by the James Dyson Foundation.
The Dyson Demo concept was originally created in Paris, France in 1999, also designed by WilkinsonEyre. A space was created in Tokyo, Japan last year, and in Jakarta, Indonesia earlier this year. Dyson hopes to roll out more Demo retail spaces worldwide, including in the U.S.
The interactive learning environment concept is similar to that of Apple, which opened a San Francisco learning space earlier this year. The first similar conceptual Apple store was opened in 2001.
The Dyson Demo London retail space is based at 447 Oxford Street, London and opens 6 July.

Doppler Labs has designed a set of sound-customising earphones, which can be used for everything from dealing with an open office to amplifying hearing.
The product includes two wireless bluetooth earbuds and a connected mobile app that use Doppler Labs' sound-morphing technology.
A limited release of 10,000 of its first generation Hear Active Listening earphones were distributed in January to people including early backers and professional musicians.
They had several features, including real-world volume control, EQ and sound effects.
The earphones were tried out at events such as LA music festival, Coachella, where users were able to customise their festival experience by altering sound settings such as the bass level.
While Hear Active Listening received positive feedback when it came to music functionality, the tech company's focus for the second generation Here One earphones was more on everyday use.
Features include highly targeted adaptive filtering, meaning that the wearer will be able to block out or turn down sounds such as sirens or crying babies, as well as layered listening that blends the sound coming from the headphones with the outside world.
This means that in the future you could be watching a baseball game in person while having commentary layered over the top.
Here One goes on sale to the public in November, and will cost $299 (£228).

On July 4th, NASA Television aired live coverage of the solar-powered Juno spacecraft's arrival at Jupiter after an almost five-year journey. Juno is the first spacecraft to orbit the poles of our solar system's most massive planet. It will circle the Jovian world 37 times during 20 months, skimming to within 3,100 miles (5,000 kilometers) above the cloud tops, providing new answers to ongoing mysteries about the planet's core, composition and magnetic fields.
After an almost five-year journey to the solar system's largest planet, NASA's Juno spacecraft successfully entered Jupiter's orbit during a 35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 p.m. PDT (11:53 p.m. EDT) Monday, July 4.
“Independence Day always is something to celebrate, but today we can add to America's birthday another reason to cheer -- Juno is at Jupiter,” said NASA administrator Charlie Bolden. “And what is more American than a NASA mission going boldly where no spacecraft has gone before? With Juno, we will investigate the unknowns of Jupiter's massive radiation belts to delve deep into not only the planet's interior, but into how Jupiter was born and how our entire solar system evolved.”
Confirmation of a successful orbit insertion was received from Juno tracking data monitored at the navigation facility at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, as well as at the Lockheed Martin Juno operations center in Littleton, Colorado. The telemetry and tracking data were received by NASA's Deep Space Network antennas in Goldstone, California, and Canberra, Australia.
“This is the one time I don't mind being stuck in a windowless room on the night of the 4th of July,” said Scott Bolton, principal investigator of Juno from Southwest Research Institute in San Antonio. “The mission team did great. The spacecraft did great. We are looking great. It's a great day.”
Preplanned events leading up to the orbital insertion engine burn included changing the spacecraft's attitude to point the main engine in the desired direction and then increasing the spacecraft's rotation rate from 2 to 5 revolutions per minute (RPM) to help stabilize it..
The burn of Juno's 645-Newton Leros-1b main engine began on time at 8:18 p.m. PDT (11:18 p.m. EDT), decreasing the spacecraft's velocity by 1,212 miles per hour (542 meters per second) and allowing Juno to be captured in orbit around Jupiter. Soon after the burn was completed, Juno turned so that the sun's rays could once again reach the 18,698 individual solar cells that give Juno its energy.
“The spacecraft worked perfectly, which is always nice when you're driving a vehicle with 1.7 billion miles on the odometer,” said Rick Nybakken, Juno project manager from JPL. “Jupiter orbit insertion was a big step and the most challenging remaining in our mission plan, but there are others that have to occur before we can give the science team the mission they are looking for.”
Over the next few months, Juno's mission and science teams will perform final testing on the spacecraft's subsystems, final calibration of science instruments and some science collection.
“Our official science collection phase begins in October, but we've figured out a way to collect data a lot earlier than that,” said Bolton. “Which when you're talking about the single biggest planetary body in the solar system is a really good thing. There is a lot to see and do here.”
Juno's principal goal is to understand the origin and evolution of Jupiter. With its suite of nine science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras. The mission also will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system. As our primary example of a giant planet, Jupiter also can provide critical knowledge for understanding the planetary systems being discovered around other stars.
One of Juno's primary missions is to peer deep inside the gas giant and unravel the mystery of how it generates its powerful magnetic field, the strongest in the solar system. One theory is that about halfway to Jupiter's core, the pressures and temperatures become so intense that the hydrogen that makes up 90 percent of the planet -- molecular gas on Earth -- looses hold of its electrons and begins behaving like a liquid metal. Oceans of liquid metallic hydrogen surrounding Jupiter's core would explain its powerful magnetic field.
The Juno spacecraft launched on Aug. 5, 2011 from Cape Canaveral Air Force Station in Florida. JPL manages the Juno mission for NASA. Juno is part of NASA's New Frontiers Program, managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for the agency's Science Mission Directorate. Lockheed Martin Space Systems in Denver built the spacecraft. The California Institute of Technology in Pasadena manages JPL for NASA.

Hundreds of hidden nearby galaxies have been studied for the first time, shedding light on a mysterious gravitational anomaly dubbed the Great Attractor, which appears to be drawing the Milky Way and hundreds of thousands of other galaxies towards it with a gravitational force equivalent to a million billion Suns. Despite being just 250 million light years from Earth--very close in astronomical terms--the new galaxies had been hidden from view until now by the Milky Way.
Using CSIRO's Parkes radio telescope equipped with an innovative receiver, an international team of scientists were able to see through the stars and dust of the Milky Way, into a previously unexplored region of space. Lead author Lister Staveley-Smith, from The University of Western Australia node of the International Centre for Radio Astronomy Research (ICRAR), said the team found 883 galaxies, a third of which had never been seen before. "The Milky Way is very beautiful of course and it's very interesting to study our own galaxy but it completely blocks out the view of the more distant galaxies behind it," he said.
Staveley-Smith said scientists have been trying to get to the bottom of the mysterious Great Attractor since major deviations from universal expansion were first discovered in the 1970s and 1980s. "We don't actually understand what's causing this gravitational acceleration on the Milky Way or where it's coming from," he said.
The Milky Way resides in the outskirts of the Laniakea Supercluster, 500 million light-years in diameter and contains the mass of one hundred million billion Suns spread across 100,000 galaxies.. Within the boundaries of the Laniakea Supercluster, galaxy motions are directed inward, in the same way that water streams follow descending paths toward a valley. The Great Attractor region is a large flat bottom gravitational valley with a sphere of attraction that extends across the Laniakea Supercluster.
"We know that in this region there are a few very large collections of galaxies we call clusters or superclusters, and our whole Milky Way is moving towards them at more than two million kilometers per hour."
"Laniakea," which means "immense heaven" in Hawaiian. This discovery clarifies the boundaries of our galactic neighborhood and establishes previously unrecognized linkages among various galaxy clusters in the local Universe.The Milky Way resides in the outskirts of the supercluster, whose extent has for the first time been carefully mapped using these new techniques. This so-called Laniakea Supercluster is 500 million light-years in diameter and contains the mass of one hundred million billion Suns spread across 100,000 galaxies.
This study also clarifies the role of the Great Attractor, a gravitational focal point in intergalactic space that influences the motion of our Local Group of galaxies and other galaxy clusters. Within the boundaries of the Laniakea Supercluster, galaxy motions are directed inward, in the same way that water streams follow descending paths toward a valley. The Great Attractor region is a large flat bottom gravitational valley with a sphere of attraction that extends across the Laniakea Supercluster.
The Milky Way and its neighboring Andromeda galaxy, along with some 30 smaller ones, form what is known as the Local Group, which lies on the outskirts of a “super cluster”—a grouping of thousands of galaxies—known as Virgo shown in the image above, which is also pulled toward the Great Attractor. Based on the velocities at these scales, the unseen mass inhabiting the voids between the galaxies and clusters of galaxies amounts to perhaps 10 times more than the visible matter.
Even so, adding this invisible material to luminous matter brings the average mass density of the universe still to within only 10-30 percent of the critical density needed to "close" the universe. This phenomena suggests that the universe be "open." Cosmologists continue to debate this question, just as they are also trying to figure out the nature of the missing mass, or "dark matter."
It is believed that this dark matter dictates the structure of the Universe on the grandest of scales. Dark matter gravitationally attracts normal matter, and it is this normal matter that astronomers see forming long thin walls of super-galactic clusters.
Recent measurements with telescopes and space probes of the distribution of mass in M31 -the largest galaxy in the neighborhood of the Milky Way- and other galaxies led to the recognition that galaxies are filled with dark matter and have shown that a mysterious force—a dark energy—fills the vacuum of empty space, accelerating the universe's expansion.
Astronomers now recognize that the eventual fate of the universe is inextricably tied to the presence of dark energy and dark matter.The current standard model for cosmology describes a universe that is 70 percent dark energy, 25 percent dark matter, and only 5 percent normal matter.
We don't know what dark energy is, or why it exists. On the other hand, particle theory tells us that, at the microscopic level, even a perfect vacuum bubbles with quantum particles that are a natural source of dark energy. But a naïve calculation of the dark energy generated from the vacuum yields a value 10120 times larger than the amount we observe. Some unknown physical process is required to eliminate most, but not all, of the vacuum energy, leaving enough left to drive the accelerating expansion of the universe.
A new theory of particle physics is required to explain this physical process. The new "dark attractor" theories skirt the so-called Copernican principle that posits that there is nothing special about us as observers of the universe suggesting that the universe is not homogeneous. These alternative theories explain the observed accelerated expansion of the universe without invoking dark energy, and instead assume we are near the center of a void, beyond which a denser "dark" attractor pulls outwards.
In a paper in Physical Review Letters, Pengjie Zhang at the Shanghai Astronomical Observatory and Albert Stebbins at Fermilab show that a popular void model, and many others aiming to replace dark energy, don't stand up against telescope observation.
Galaxy surveys show the universe is homogeneous, at least on length scales up to a gigaparsec. Zhang and Stebbins argue that if larger scale inhomogeneities exist, they should be detectable as a temperature shift in the cosmic microwave background—relic photons from about 400,000 years after the big bang—that occurs because of electron-photon (inverse Compton) scattering.
Focusing on the “Hubble bubble” void model, they show that in such a scenario, some regions of the universe would expand faster than others, causing this temperature shift to be greater than what is expected. But telescopes that study the microwave background, such as the Atacama telescope in Chile or the South Pole telescope, don't see such a large shift.
Though they can't rule out more subtle violations of the Copernican principle, Zhang and Stebbins' test reinforces Carl Sagan's dictum that "extraordinary claims require extraordinary evidence."
Superclusters are among the largest structures in the known Universe. They are made up of groups, like our own Local Group, that contain dozens of galaxies, and massive clusters that contain hundreds of galaxies, all interconnected in a web of filaments. Though these structures are interconnected, they have poorly defined boundaries.
"We have finally established the contours that define the supercluster of galaxies we can call home," said R. Brent Tully, an astronomer at the University of Hawaii at Manoa. "This is not unlike finding out for the first time that your hometown is actually part of much larger country that borders other nations."
To better refine cosmic mapmaking, the researchers are proposing a new way to evaluate these large-scale galaxy structures by examining their impact on the motions of galaxies. A galaxy between structures will be caught in a gravitational tug-of-war in which the balance of the gravitational forces from the surrounding large-scale structures determines the galaxy's motion.
By using the GBT and other radio telescopes to map the velocities of galaxies throughout our local Universe, the team was able to define the region of space where each supercluster dominates. "Green Bank Telescope observations have played a significant role in the research leading to this new understanding of the limits and relationships among a number of superclusters," said Tully.
The name Laniakea was suggested by Nawa'a Napoleon, an associate professor of Hawaiian Language and chair of the Department of Languages, Linguistics, and Literature at Kapiolani Community College, a part of the University of Hawaii system. The name honors Polynesian navigators who used knowledge of the heavens to voyage across the immensity of the Pacific Ocean.
The GBT is the world's largest fully steerable radio telescope. Its location in the National Radio Quiet Zone and the West Virginia Radio Astronomy Zone protects the incredibly sensitive telescope from unwanted radio interference.
The new CSIRO research identified several new structures that could help to explain the movement of the Milky Way, including three galaxy concentrations (named NW1, NW2 and NW3) and two new clusters (named CW1 and CW2). The study involved researchers from Australia, South Africa, the U.S. and the Netherlands, and was published in the Astronomical Journal.
University of Cape Town astronomer Renée Kraan-Korteweg said astronomers have been trying to map the galaxy distribution hidden behind the Milky Way for decades. "We've used a range of techniques but only radio observations have really succeeded in allowing us to see through the thickest foreground layer of dust and stars," she said. "An average galaxy contains 100 billion stars, so finding hundreds of new galaxies hidden behind the Milky Way points to a lot of mass we didn't know about until now."
