According to a recent poll, just 10 per cent of Americans are excited about voting for either of the two political parties' presidential candidates in November.…
Last year, the United Nations estimated there were more than 21 million refugees scattered across the globe—a level unseen since World War II. As the 2016 Olympic games approached, International Olympic Committee President Thomas Bach saw an opportunity to focus global attention on the crisis, and to give some of the athletes among this huge stateless population a chance to compete on the world stage. The IOC selected a group of 10 refugee athletes from South Sudan, Syria, Congo and Ethiopia to compete for the newly-formed Refugee Olympic Team. During the Opening Ceremony, the team will march into the stadium carrying the Olympic flag.

New EU regulation blacklists 37 non-native plant and animal species in a bid to tackle threats to native wildlife and economic losses
The north American raccoon, an Asian hornet and an American cabbage are among 37 invasive species that will be banned from being brought into the UK from Wednesday when a new EU regulation comes into effect.
The continent-wide rules now make it illegal to import, keep, breed or grow, transport, sell or use, or release into the environment without a permit the listed invasive, non-native plant and animal species. But the ban will no longer apply when then UK leaves the EU.

Continue reading...If you've eaten at a Chili's, Uno Pizzeria, or Applebee's in recent years, you might have encountered a touchscreen menu: a tablet from which you can select your order instead of talking to a server. Uno found that installing touchscreen menus in some restaurants pushed their dessert sales up by 30 percent, Planet Money reported last year. “One theory is that customers feel like waiters will judge them if they order dessert right after they've eaten a huge pizza,” said reporter Stacey Vanek Smith, whereas a machine won't judge them.
In a paper soon to be published in the Journal of Marketing Research, a trio of researchers offer an alternate explanation: Using touchscreens to select food makes us feel like we are actually reaching toward that food to grab it, which makes us more likely to select “affect-laden products” (like cheesecake) than “cognitively superior products” (like fruit salad). Hao Shen and Meng Zhang of the Chinese University of Hong Kong and Aradhna Krishna of the University of Michigan found that university students in Hong Kong were more likely to choose hypothetical junk food over hypothetical healthier options when they used a touchscreen than when they used a desktop computer with a mouse. Interestingly, the effect also held when the researchers compared touching a touchscreen to using a stylus on a touchscreen. It was the act of touching the screen that apparently triggered hedonistic choices, rather than the convenience or interface of the touchscreen.
A few caveats are necessary: The studies used a small sample size in each phase of the study, between 85 and 228 students. Some of the students participated for extra credit, and the others were paid the equivalent of $1.30, which means they might not have had much of an incentive to take the study seriously. And the effect of touching the touchscreen was not huge: 95 percent of people using a touchpad selected hypothetical cheesecake over hypothetical fruit salad, but so did 73 percent of people using a desktop computer. Yes, the touchscreen apparently lowered people's resistance to the cheesecake, but most people were going to choose cheesecake no matter what.
This isn't the first (or last) study to attempt to tease out how external factors can affect what and how much we eat. Think of all those studies on whether plate size affects consumption, or a recent study showing that people make healthier food choices when they eat under bright lights. These kinds of studies are useful for the food service industry, which can use findings like this to bolster sales of items with a high profit margin. (It's no coincidence that the researchers behind the touchscreen study are professors of marketing.) These studies are also useful for regulators who want to understand how food manufacturers and vendors exploit consumers' unconscious weaknesses. They're also arguably just plain interesting, even if their conclusions ought to be taken with a grain of salt.
But I worry that studies like this play into a larger cultural narrative—one that also gets pushed by the diet industry, often onto women—that people just can't trust themselves around food, that our instincts will lead us astray. A person who is concerned about his or her eating habits or weight might read about this study and conclude, “Oh god, I won't be able to control myself if I follow my gut; my intuition is trying to undermine me.” This is the harmful notion that underpins most eating disorders. It's self-evident that external factors affect what one eats, but that doesn't mean that eating healthfully requires rigidly counting every calorie so that you don't fall prey to touchscreens or big plates or dim lighting. People can trust your gut if they eat when they're hungry, stop eating when they're full, and pay attention to how different foods make them feel. If you're not used to eating intuitively, this is really hard, and even scary, at first—but once you get the hang of it, the possibility that a touchscreen might have a small influence on your order won't freak you out. And neither will the possibility that you might sometimes choose cheesecake over fruit salad.
JM Barrie's boy who never grew up shows the author understood key aspects of infant cognition decades ahead of academics, argues neuroscientist
JM Barrie might be most famous for his classic story of a flying boy who never grows up, but the author was also far ahead of his time when it came to cognitive psychology, according to a Cambridge academic who argues in a new book that the Peter Pan author's whimsical stories deliberately explore the nature of cognition.
Neuroscientist Rosalind Ridley, of Newnham College in Cambridge, claims in the just-published Peter Pan and the Mind of JM Barrie that the author's work identifies key stages of child development. One scene she spotlights in Peter Pan in Kensington Gardens, published in 1906, sees a girl giving a tearful Peter her handkerchief, which he is confused by. “So she showed him, that is to say she wiped her eyes, and then gave it back to him, saying: ‘Now you do it,' but instead of wiping his own eyes he wiped hers, and she thought it would be best to pretend that this is what she had meant,” writes Barrie.

Claressa Shields was just 17 years old when she won the gold medal for women's boxing in London in 2012, and now she's ranked first going into the 2016 Olympics in Rio de Janeiro. This excerpt from the feature-length documentary, T-Rex: Her Fight for Gold, is a glimpse of how challenging it's been for Shields to ascend to boxing greatness from her hometown of Flint, Michigan. The film is a beautiful, coming-of-age tale that emphasizes the transience and disappointments of athletic success. Despite her wins, Shields has to contend with not receiving the recognition and endorsements that come to many other Olympic champions. The full documentary airs August 2, 2016, on PBS, and will stream online during the month of August. For more information, visit the Independent Lens website.
There are several things going on when you see someone looking at you, all of which happen very quickly.
This applies to actually seeing someone looking at you, not "sensing it" from behind or in the periphery.
Primates (including humans) are unique in the degree to which the eyeball can move around in the eye socket. This allows visual attention to be shifted quickly without physically moving the head.
Primates and certain other mammals can tell when another animal is looking at them, but humans are particularly good at doing this from a distance. In fact, humans have the added ability to be able to tell where someone is looking, even when it is not at them.
It is easy to see why this skill confers an evolutionary advantage: By being able to do this, you can essentially "read out" the location of another animal's attention. If you are a social animal, and the one looking at you is a superior, you'd better behave. Or if it is an inferior, you are being challenged and need to respond so you don't lose your place in the status hierarchy. For humans, knowing where another human is looking allows you to read their mind regarding what they are thinking about. This is invaluable when trying to learn language, since it allows you to pair particular words with particular objects in the environment. Pointing is also effective for this.
So, how do we do it?
Detecting the direction of gaze has to do with noticing the relative location of the dark spot of the eye (the pupil and iris) in the context of the whites of the eye. The differential size and location of the white region shows where the eye is pointed. And if the pupil is exactly in the middle with equal white regions on each side, then the eyes are looking at you. We can see this from across the room. Head direction also provides a cue, which is primarily determined by where the region of the two eyes and the nose are relative to oval face region, with hair as another reference marker. When the head is turned, the brain has to do some geometry to determine gaze direction from both head angle and relative eye angle.
Figure: Ratio of dark to light region of eye reveals direction of gaze. Bottom row: Location of facial features relative to head reveals head orientation. The visual system combines head orientation and eye orientation to calculate direction of gaze.
There is an additional effect that happens when "eyes meet". When you look at someone and they look back, you have the feeling that your gaze was met. This can feel uncomfortable, and the person who was "caught" often quickly looks away. This effect is caused by a feedback loop. The second person to make eye contact sees immediately that the first person is looking at them. The first person realizes they were "discovered" and responds often according to perceived relative status or confidence. There is also the mutual knowing that eyes met, which becomes a shared event establishing a transient relationship.
The meeting of gaze helps people recognize each other. You may think you recognize someone, but if they seem to think they recognize you too by not looking away, then the odds are greater that you are both correct. The visual systems of both individuals thus collaborate to establish mutual recognition. This happens quickly and subconsciously, allowing the social exchange to move forward toward acknowledging each other. If one person doesn't acknowledge back, it becomes an awkward case of mistaken identity.
Public speakers use the illusion of eye contact to create emotional intimacy with the audience. When people learn public speaking, they are told to glance around the room as they talk. This creates the illusion of intermittent eye contact with as many people in the room as possible, which allows the audience to feel that the speaker is talking to them personally, creating a feeling of intimacy with the speaker.
When TV newscasters deliver the news, they want the audience to have the impression they are talking to them. To accomplish this, they talk to the camera lens as if it was a person. In movies, actors avoid looking at the camera so that the audience never experiences mutual eye contact with them, preserving the feeling that the viewer is invisible. To look at the camera is called "breaking the fourth wall."

Continue reading...Robert Welch Designs has reproduced the six-slice Campden toast rack in a limited edition run to mark the product's 60th anniversary.
The new edition of the Campden toast rack is £40 and is available to buy from the new Design Museum shop in London.
There are only 600 copies of the reissued toast rack available, which are numbered and come with a replicate of its original packaging.
The Campden is a simple, stainless steel toast rack, which was first produced for kitchenware company Old Hall, where Welch was consultant designer.
It was first produced in 1956 in four and six-slice options, and remained in manufacture until 1982, when it was discontinued.
It was one of three award-winning products Welch produced for Old Hall, alongside a range of 22 dishes and the distinctive Alveston range of cutlery, known for its inverted or “hollow” handles, which aim to provide balance.
The toast rack was part of the Campden collection, which included saucepans, candle holders, a coffee set, cutlery and salt and pepper shakers.
It was also exhibited as a single item, seen at Robert's first solo exhibition at Foyle's Art Gallery in 1956, and received a Council of Industrial Design award in 1957, where it was described as having “elegant and ingenious construction”. The toast rack was also included in the council's annual Design of the Year exhibition in 1958.
The Campden range's simple aesthetic made it unique in the 1950s, as Welch's designs conveyed a rawness and realism while other manufacturers adopted ornate styles.
It was named after the designer's design studio based on the top floor of the Old Silk Mill in Chipping Campden, the Cotswolds, which he set up in 1955.
Alongside the Design Museum, the reissued toast rack is also available to buy from the Robert Welch website, or from the Robert Welch shops in Chipping Campden and Bath, and the Compton Verney shop in Warwickshire.

The creative industries are growing faster than any other business sector across the majority of the UK, with design outstripping the likes of advertising, architecture and film, according to a new report.
The Geography of Creativity, produced by charities Nesta and Creative England, highlights the Department for Culture, Media and Sport's (DCMS) findings that the Gross Value Added for the creative industries was £81.4 billion in 2014.
Within these industries, the report finds that the design sub-sector alongside software and digital businesses has some of the highest rates of growth.
Comparing data from 2007 to 2014 from sources including the Office for National Statistics, the report shows that businesses within the design industry have an average growth rate of over 20%, and over 30% when viewed in terms of turnover and employment rates.
While London is shown to be the dominant location in most creative sub-sectors responsible for 40% of jobs and a third of creative businesses the report also highlights smaller hotspots of creative activity thriving across the rest of the UK as well.
In total the report counts a total of 47 “creative clusters” all over the country. It suggests that around one in five of these are in the North of England, with Scotland and Wales also identified as having “thriving creative ecossytems”.
The report differentiates between “creative cities” such as Glasgow, Manchester and Brighton which tend to have highly diversified creative industries, while “creative conurbations” including Slough and High Wycombe are generally more specialised.
“These clusters specialising in a smaller number of creative sub-sectors with a high technology component may be less ‘hip' than creative cities like Brighton, Liverpool and Glasgow, but our research suggests they make significant economic contributions,” according to the report.
“In particular, they are associated with larger-sized creative businesses, and potentially higher levels of business productivity.”
Despite the high levels of growth and productivity among creative sectors such as design, the report also suggests that more support ought to be offered to creative businesses on both a local and national level.
“Over half of Local Enterprise Partnerships fail to even mention the creative industries in their strategy plans. We hope that the evidence that we have presented in this report…will persuade some of them to…take action to boost the creative industries growth that is taking place on their doorstep,” says the report.
“We also believe that national and devolved governments can play a more active role to scale up creative clusters outside London and the South East, with well-resourced, locally relevant interventions along the lines of Nesta's previous recommendations.”
Caroline Norbury, chief executive of Creative England, adds: “This report clearly shows the power of the creative industries to drive jobs and prosperity not only in London and the south east, but in communities across the UK.
“”It is more crucial now than perhaps ever before, that we work together to make sure our creative industries are equipped to play their part in driving a strong economy and maintaining our position as a world leader in an increasingly competitive global marketplace.”

The Beijing Organising Committee for the 2022 Olympic and Paralympic Winter Games has announced it is looking for expressions of interest for the logo design of both competitions.
The games are set to take place in Beijing and Zhangijakou in 2022. At an event to mark the one-year anniversary of Beijing winning the bid, the organising committee set out broad proposals for the identity competition.
Both Olympic and Paralympic identities will need to reference the Beijing event and broader Chinese culture, according to the committee, which hopes the identity will be “globally accepted” and “demonstrate the Chinese image to the world.”
The identity will need to capture the Olympic and Paralympic spirit and embody the culture and values of the host city and country. Furthermore the logos need to be inspiring and show that they can be recognised by domestic and international communities, according to organisers.
Designs will need to stand up to the requirements of TV broadcasters, visual effects and digital platforms.
A series of key words and phrases have been given as broad guidelines for designers. These include running the Games in a “green, open, shared and honest manner”, the idea of “millions of people participating in winter sports,” as well as sustainable development and cues such as “cohesion, sport, strength,” and “world, reunion, festival”.
There are currently no detailed briefing documents available. The organising committee says that the “technical documents” will be “available to the public shortly”.
At the time of publication The Beijing Organising Committee for the 2022 Olympic and Paralympic Winter Games was unable to confirm whether it was looking for professional designers to bid.

Pixar has mastered the art of making grown-ups cry, and in films like Up, Monsters Inc, and Toy Story 3, the score plays a big part in eliciting that emotion. So why doesn't every movie simply add sad music to an already sad scene? It's not that easy, warns Youtuber Sideways, in this smart video essay that explains how the process is way more complicated than simply changing the key.
If you want to create an emotional response, the essay argues, the best method is to create dissonance between what the audience hears, and what they see. That's what gives us such effective tearjerkers as “Ellie's Theme” and “So Long”—both songs that were used in happier scenes before transforming others from sad to devastating. And it's a lesson that other movies could learn from, as Sideways so ably demonstrates here.
A major revision is required in our understanding of our Milky Way Galaxy according to an international team led by Prof Noriyuki Matsunaga of the University of Tokyo. The Japanese, South African and Italian astronomers find that there is a huge region around the center of our own Galaxy, which is devoid of young stars.
The Milky Way is a spiral galaxy containing many billions of stars with our Sun about 26,000 light years from its centre. Measuring the distribution of these stars is crucial to our understanding of how our Galaxy formed and evolved. Pulsating stars called Cepheids are ideal for this. They are much younger (between 10 and 300 million years old) than our Sun (4.6 billion years old) and they pulsate in brightness in a regular cycle. The length of this cycle is related to the luminosity of the Cepheid, so if astronomers monitor them they can establish how bright the star really is, compare it with what we see from Earth, and work out its distance.
The artist's impression below shows the implied distribution of young stars, represented here by Cepheids shown as blue stars, plotted on the background of a drawing of the Milky Way.
Despite this, finding Cepheids in the inner Milky Way is difficult, as the Galaxy is full of interstellar dust which blocks out light and hides many stars from view. Matsunaga's team compensated for this, with an analysis of near-infrared observations made with a Japanese-South African telescope located at Sutherland, South Africa. To their surprise they found hardly any Cepheids in a huge region stretching for thousands of light years from the core of the Galaxy.
Noriyuki Matsunaga explains: "We already found some while ago that there are Cepheids in the central heart of our Milky Way (in a region about 150 light years in radius). Now we find that outside this there is a huge Cepheid desert extending out to 8000 light years from the center."
This suggests that a large part of our Galaxy, called the Extreme Inner Disk, has no young stars. Co-author Michael Feast notes: "Our conclusions are contrary to other recent work, but in line with the work of radio astronomers who see no new stars being born in this desert."
Another author, Giuseppe Bono, points out: "The current results indicate that there has been no significant star formation in this large region over hundreds of millions years. The movement and the chemical composition of the new Cepheids are helping us to better understand the formation and evolution of the Milky Way."
Cepheids have more typically been used to measure the distances of objects in the distant Universe, and the new work is an example instead of the same technique revealing the structure of our own Milky Way.
The team publish their work in a paper in Monthly Notices of the Royal Astronomical Society.

China is planning to build an enormous particle accelerator twice the size and seven times as powerful as CERN's Large Hadron Collider, according to state media reports. According to China Daily, the new facility will be capable of producing millions of Higgs boson particles - a great deal more than the Large Hadron Collider which originally discovered the ‘God particle' back in 2012.
"We have completed the initial conceptual design and organized international peer review recently, and the final conceptual design will be completed by the end of 2016," Wang Yifang, director of the Institute of High Energy Physics, Chinese Academy of Sciences, told China Daily in an exclusive interview.
The institute has been operating major high-energy physics projects in China, such as the Beijing Electron Positron Collider and the Daya Bay Reactor Neutrino experiment. Now scientists are proposing a more ambitious new accelerator with seven times the energy level of the Large Hadron Collider in Europe. The first phase of the project's construction is scheduled to begin between 2020 and 2025.
“So far the Standard Model seems to explain matter, but we know there has to be something beyond the Standard Model,” said Denise Caldwell, director of the Physics Division of the National Science Foundation. “This potential new physics can only be uncovered with more data that will come with the next LHC run.”
The Standard Model contains no explanation of gravity, which is one of the four fundamental forces in the universe. It also does not explain astronomical observations of dark matter, a type of matter that interacts with our visible universe only through gravity, nor does it explain why matter prevailed over antimatter during the formation of the early universe. The small mass of the Higgs boson also suggests that matter is fundamentally unstable.
Gerald Hooft, winner of the Nobel Prize in Physics, said in an interview to Doha-based broadcaster Al Jazeera that China's proposed collider, if built, "will bring hundreds, probably thousands, of top class scientists with different specializations, from pure theory to experimental physics and engineering, from abroad to China". Chinese scientists have completed an initial conceptual design of a super giant particle collider which will be bigger and more powerful than any particle accelerator on Earth.
In July 2012, the European Organization for Nuclear Research, also known as CERN, announced that it had discovered the long sought-after Higgs boson-the "God particle", regarded as the crucial link that could explain why other elementary particles have mass-on LHC. The discovery was believed to be one of the most important in physics for decades. Scientists are hopeful that it will further explain nature and the universe we live in.
The high-energy frontier has traditionally had one primary goal, to probe directly any uncharted physics waters. This has translated into the gigantic effort to complete the unobserved elements of the Standard Model of particle physics as well as to search for for signs of physics beyond.These measurements form a solid base from which searches for physics beyond the standard model have been launched. Since the discovery of the Higgs in 2012, searches for supersymmetry and several signatures of possible new exotic physics phenomena have been developed, and new parameter space is being explored.
In 2016, the Large Hadron Collider, the world's most powerful proton smasher, is preparing for its biggest run yet which scientists hope will uncover new particles that could dramatically change our understanding of the Universe. Scientists had been gearing up to resume experiments at the LHC this week, but the plans were delayed after a weasel wandered onto a high-voltage electrical transformer last Friday, causing a short-circuit. CERN told AFP that experiments were now expected to get underway next week.
The LHC, housed in a 27-kilometre (17-mile) tunnel straddling the French-Swiss border, has shaken up physics before. In 2012 it was used to prove the existence of the Higgs Boson -- the long-sought maker of mass -- by crashing high-energy proton beams at velocities near the speed of light. (A proton-lead ion collision, shown below as observed by the LHCb detector during the 2013 data-taking period LHCb/CERN). The giant lab might prove the exotic theory of supersymmetry, SUSY for short, which suggests the existence of a heavier "sibling" for every particle in the universe. The unexpected excess pair of photons spotted last year could be a larger cousin of the Higgs, according to one theory.
While LHC is composed of 27-kilometer-long accelerator chains and detectors buried 100 meters underground at the border of Switzerland and France, scientists only managed to spot hundreds of Higgs boson particles, not enough to learn the structure and other features of the particle.
With a circumference of 50 to 100 km, however, the proposed Chinese accelerator Circular Electron Positron Collider (CEPC) will generate millions of Higgs boson particles, allowing a more precise understanding.
"The technical route we chose is different from LHC. While LHC smashes together protons, it generates Higgs particles together with many other particles," Wang said. "The proposed CEPC, however, collides electrons and positrons to create an extremely clean environment that only produces Higgs particles," he added.
The Higgs boson factory is only the first step of the ambitious plan. A second-phase project named SPPC (Super Proton-Proton Collider) is also included in the design-a fully upgraded version of LHC.
LHC shut down for upgrading in early 2013 and restarted in June with an almost doubled energy level of 13 TeV, a measurement of electron volts.
"LHC is hitting its limits of energy level, it seems not possible to escalate the energy dramatically at the existing facility," Wang said. The proposed SPPC will be a 100 TeV proton-proton collider.
If everything moves forward as proposed, the construction of the first phase project CEPC will start between 2020 and 2025, followed by the second phase in 2040.
"China brings to this entire discussion a certain level of newness. They are going to need help, but they have financial muscle and they have ambition," said Nima Arkani Hamed from the Institute for Advanced Study in the United States, who joined the force to promote CEPC in the world.
David J. Gross, a US particle physicist and 2004 Nobel Prize winner, wrote in a commentary co-signed by US theoretical physicist Edward Witten that although the cost of the project would be great, the benefits would also be great. "China would leap to a leadership position in an important frontier area of basic science," he wrote.

The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older than ours. However, new theoretical work suggests that present-day life is actually premature from a cosmic perspective.
"If you ask, 'When is life most likely to emerge?' you might naively say, 'Now,'" says lead author Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. "But we find that the chance of life grows much higher in the distant future."
Life as we know it first became possible about 30 million years after the Big Bang, when the first stars seeded the cosmos with the necessary elements like carbon and oxygen. Life will end 10 trillion years from now when the last stars fade away and die. Loeb and his colleagues considered the relative likelihood of life between those two boundaries.
The dominant factor proved to be the lifetimes of stars. The higher a star's mass, the shorter its lifetime. Stars larger than about three times the sun's mass will expire before life has a chance to evolve.
Conversely, the smallest stars weigh less than 10 percent as much as the Sun. They will glow for 10 trillion years, giving life ample time to emerge on any planets they host. As a result, the probability of life grows over time. In fact, chances of life are 1000 times higher in the distant future than now.
"So then you may ask, why aren't we living in the future next to a low-mass star?" says Loeb. "One possibility is we're premature. Another possibility is that the environment around a low-mass star is hazardous to life."
Although low-mass, red dwarf stars live for a long time, they also pose unique threats. In their youth they emit strong flares and ultraviolet radiation that could strip the atmosphere from any rocky world in the habitable zone.
To determine which possibility is correct -- our premature existence or the hazard of low-mass stars -- Loeb recommends studying nearby red dwarf stars and their planets for signs of habitability. Future space missions like the Transiting Exoplanet Survey Satellite and James Webb Space Telescope should help to answer these questions.

Atmospheric temperatures on Jupiter range from around 1,700 degrees Fahrenheit to upward of 2,420 degrees. That's greater than the temperature of molten lava and would cause lithium batteries in cellphones to boil and turn to gas. These wide ranges in temperature could not just be explained by heat from the sun, said James O'Donoghue, a research scientist at Boston University's Center for Space Physics.
Researchers from Boston University's (BU) Center for Space Physics report today in Nature that Jupiter's Great Red Spot may provide the mysterious source of energy required to heat the planet's upper atmosphere to the unusually high values observed.
Sunlight reaching Earth efficiently heats the terrestrial atmosphere at altitudes well above the surfaceeven at 250 miles high, for example, where the International Space Station orbits. Jupiter is over five times more distant from the Sun, and yet its upper atmosphere has temperatures, on average, comparable to those found at Earth. The sources of the non-solar energy responsible for this extra heating have remained elusive to scientists studying processes in the outer solar system.
“With solar heating from above ruled out, we designed observations to map the heat distribution over the entire planet in search for any temperature anomalies that might yield clues as to where the energy is coming from,” explained Dr. James O'Donoghue, research scientist at BU, and lead author of the study.
Astronomers measure the temperature of a planet by observing the non-visible, infrared (IR) light it emits. The visible cloud tops we see at Jupiter are about 30 miles above its rim; the IR emissions used by the BU team came from heights about 500 miles higher. When the BU observers looked at their results, they found high altitude temperatures much larger than anticipated whenever their telescope looked at certain latitudes and longitudes in the planet's southern hemi-sphere.
Jupiter's Great Red Spot (GRS) is one of the marvels of our solar system. Discovered within years of Galileo's introduction of telescopic astronomy in the 17th Century, its swirling pattern of colorful gases is often called a “perpetual hurricane.” The GRS has varied is size and color over the centuries, spans a distance equal to three earth-diameters, and has winds that take six days to complete one spin. Jupiter itself spins very quickly, completing one revolution in only ten hours.
“The Great Red Spot is a terrific source of energy to heat the upper atmosphere at Jupiter, but we had no prior evidence of its actual effects upon observed temperatures at high altitudes,” ex-plained Dr. Luke Moore, a study co-author and research scientist in the Center for Space Physics at BU.
Solving an “energy crisis” on a distant planet has implications within our solar system, as well as for planets orbiting other stars. As the BU scientists point out, the unusually high temperatures far above Jupiter's visible disk is not a unique aspect of our solar system. The dilemma also occurs at Saturn, Uranus and Neptune, and probably for all giant exoplanets outside our solar system.
“Energy transfer to the upper atmosphere from below has been simulated for planetary atmospheres, but not yet backed up by observations,” O'Donoghue said. “The extremely high temperatures observed above the storm appear to be the ‘smoking gun' of this energy transfer, indicating that planet-wide heating is a plausible explanation for the ‘energy crisis.'”

Located approximately 22 000 light-years away in the constellation of Musca (The Fly), this tightly packed collection of stars - known as a globular cluster - goes by the name of NGC 4833. This NASA/ESA Hubble Space Telescope image shows the dazzling stellar group in all its glory.
NGC 4833 is one of the over 150 globular clusters known to reside within the Milky Way. These objects are thought to contain some of the oldest stars in our galaxy. Studying these ancient cosmic clusters can help astronomers to unravel how a galaxy formed and evolved, and give an idea of the galaxyâs age.
Globular clusters are responsible for some of the most striking sights in the cosmos, with hundreds of thousands of stars congregating in the same region of space. Hubble has observed many of these clusters during its time in orbit around our planet, each as breathtaking as the last.

In the first few minutes following “the big bang,” the universe quickly began expanding and cooling, allowing the formation of subatomic particles that joined forces to become protons and neutrons. These particles then began interacting with one another to create the first simple atoms. A little more time, a little more expansion, a lot more cooling—along with ever-present gravitational pull—and clouds of these elements began to morph into stars and galaxies.
For William Detmold, an assistant professor of physics at MIT who uses lattice quantum chromodynamics (LQCD) to study subatomic particles, one of the most interesting aspects of the formation of the early universe is what happened in those first few minutes—a period known as the “big bang nucleosynthesis.”
“You start off with very high-energy particles that cool down as the universe expands, and eventually you are left with a soup of quarks and gluons, which are strongly interacting particles, and they form into protons and neutrons,” he said. “Once you have protons and neutrons, the next stage is for those protons and neutrons to come together and start making more complicated things—primarily deuterons, which interact with other neutrons and protons and start forming heavier elements, such as Helium-4, the alpha particle.”
One of the most critical aspects of big bang nucleosynthesis is the radiative capture process, in which a proton captures a neutron and fuses to produce a deuteron and a photon. In a paper published in Physical Review Letters, Detmold and his co-authors—all members of the NPLQCD Collaboration, which studies the properties, structures and interactions of fundamental particles—describe how they used LQCD calculations to better understand this process and precisely measure the nuclear reaction rate that occurs when a neutron and proton form a deuteron. While physicists have been able to experimentally measure these phenomena in the laboratory, they haven't been able to do the same, with certainty, using calculations alone—until now.
“One of the things that is very interesting about the strong interaction that takes place in the radiative capture process is that you get very complicated structures forming, not just protons and neutrons,” Detmold said. “The strong interaction has this ability to have these very different structures coming out of it, and if these primordial reactions didn't happen the way they happened, we wouldn't have formed enough deuterium to form enough helium that then goes ahead and forms carbon. And if we don't have carbon, we don't have life.”
For the Physical Review Letters paper, the team used the Chroma LQCD code developed at Jefferson Lab to run a series of calculations with quark masses that were 10-20 times the physical value of those masses. Using heavier values rather than the actual physical values reduced the cost of the calculations tremendously, Detmold noted. They then used their understanding of how the calculations should depend on mass to get to the physical value of the quark mass.
“When we do an LQCD calculation, we have to tell the computer what the masses of the quarks we want to work with are, and if we use the values that the quark masses have in nature it is very computationally expensive,” he explained. “For simple things like calculating the mass of the proton, we just put in the physical values of the quark masses and go from there. But this reaction is much more complicated, so we can't currently do the entire thing using the actual physical values of the quark masses.
While this is the first LQCD calculation of an inelastic nuclear reaction, Detmold is particularly excited by the fact that being able to reproduce this process through calculations means researchers can now calculate other things that are similar but that haven't been measured as precisely experimentally—such as the proton-proton fusion process that powers the sun—or measured at all.
“The rate of the radiative capture reaction, which is really what we are calculating here, is very, very close to the experimentally measured one, which shows that we actually understand pretty well how to do this calculation, and we've now done it, and it is consistent with what is experimentally known,” Detmold said. “This opens up a whole range of possibilities for other nuclear interactions that we can try and calculate where we don't know what the answer is because we haven't, or can't, measure them experimentally. Until this calculation, I think it is fair to say that most people were wary of thinking you could go from quark and gluon degrees of freedom to doing nuclear reactions. This research demonstrates that yes, we can.”

"There is a powerful analogy between the Earth's first mass extinction and what is happening today," said Simon Darroch, at Vanderbilt University. "The end-Ediacaran extinction shows that the evolution of new behaviors can fundamentally change the entire planet, and today we humans are the most powerful 'ecosystems engineers' ever known."
Newly discovered fossil evidence from Namibia strengthens the proposition that the world's first mass extinction was caused by "ecosystem engineers" - newly evolved biological organisms that altered the environment so radically it drove older species to extinction. The event, known as the end-Ediacaran extinction, took place 540 million years ago. The earliest life on Earth consisted of microbes - various types of single-celled organisms. These held sway for more than 3 billion years, when the first multicellular organisms evolved. The most successful of these were the Ediacarans, which spread around the globe about 600 million years ago. They were a largely immobile form of marine life shaped like discs and tubes, fronds and quilted mattresses.
After 60 million years, evolution gave birth to another major innovation: metazoans, the first animals. Metazoans could move spontaneously and independently at least during some point in their life cycle and sustain themselves by eating other organisms or what other organisms produce. Animals burst onto the scene in a frenzy of diversification that paleontologists have labeled the Cambrian explosion, a 25 million-year period when most of the modern animal families - vertebrates, mollusks, arthropods, annelids, sponges and jellyfish - came into being.
"These new species were 'ecological engineers' who changed the environment in ways that made it more and more difficult for the Ediacarans to survive," said Darroch, assistant professor of earth and environmental sciences, who directed the new study.
Darroch and his colleagues report that they have found one of the best-preserved examples of a mixed community of Ediacarans and animals, which provides the best evidence of a close ecological association between the two groups.
"Until this, the evidence for an overlapping ecological association between metazoans and soft-bodied Ediacaran organisms was limited," Darroch said. "Here, we describe new fossil localities from southern Namibia that preserve soft-bodied Ediacara biota, enigmatic tubular organisms thought to represent metazoans and vertically oriented metazoan trace fossils. Although the precise identity of the tracemakers remains elusive, the structures bear several striking similarities with a cone-shaped organism called Conichnus that has been found in the Cambrian period."
In a previous paper that Darroch and his collaborators published last September, they reported on a fossil record that showed stressed-looking communities of Ediacara associated with a suite of animal burrows.
"With this paper we're narrowing in on causation; we've discovered some new fossil sites that preserve both Ediacara biota and animal fossils (both animal burrows - 'trace fossils' - and the remains of animals themselves) sharing the same communities, which lets us speculate about how these two very different groups of organisms interacted," he said.
Conichnus burrows are trace fossils: the surface bumps shown below represent vertical tubes that were originally occupied by anemone-like animals that may have fed on Ediacaran larvae.
"Some of the burrow fossils we've found are usually interpreted as being formed by sea anemones, which are passive predators that may have preyed upon Ediacaran larvae. We've also found stands of Ediacaran frondose organisms, with animal fossils preserved in place coiled around their bases. In general, these new fossil sites reveal a snapshot of a very unusual 'transitional' ecosystem existing right before the Cambrian explosion, with the last of the Ediacara biota clinging on for grim death, just as modern-looking animals are diversifying and starting to realize their potential."

The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older than ours. However, new theoretical work suggests that present-day life is actually premature from a cosmic perspective.
“If you ask, ‘When is life most likely to emerge?' you might naively say, ‘Now,'” says lead author Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. “But we find that the chance of life grows much higher in the distant future.”
Life as we know it first became possible about 30 million years after the Big Bang, when the first stars seeded the cosmos with the necessary elements like carbon and oxygen. Life will end 10 trillion years from now when the last stars fade away and die. Loeb and his colleagues considered the relative likelihood of life between those two boundaries.
The dominant factor proved to be the lifetimes of stars. The higher a star's mass, the shorter its lifetime. Stars larger than about three times the sun?s mass will expire before life has a chance to evolve.
Conversely, the smallest stars weigh less than 10 percent as much as the Sun. They will glow for 10 trillion years, giving life ample time to emerge on any planets they host. As a result, the probability of life grows over time. In fact, chances of life are 1000 times higher in the distant future than now.
“So then you may ask, why aren't we living in the future next to a low-mass star?” says Loeb.
“One possibility is we're premature. Another possibility is that the environment around a low-mass star is hazardous to life.”
Although low-mass, red dwarf stars live for a long time, they also pose unique threats. In their youth they emit strong flares and ultraviolet radiation that could strip the atmosphere from any rocky world in the habitable zone.
To determine which possibility is correct — our premature existence or the hazard of low-mass stars — Loeb recommends studying nearby red dwarf stars and their planets for signs of habitability. Future space missions like the Transiting Exoplanet Survey Satellite and James Webb Space Telescope should help to answer these questions.
The paper describing this work has been accepted for publication in the Journal of Cosmology and Astroparticle Physics and is available online. Its co-authors are Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Rafael Batista and David Sloan (University of Oxford). Loeb simultaneously wrote an extended review on the habitability of the universe as a chapter for a forthcoming book.

(US Capitol/US Government Work)
Washington, D.C., isn't just the seat of our national government; it's also my hometown. It's the place where I was born and have lived nearly my whole life. I attended the very first Earth Day rally here in 1970. I've also spent over three decades working here, under six presidential administrations and on a wide variety of issues.
During this time, I've seen how things operate. Those who pollute our environment continue to send a swarm of hired lobbyists to this town. They blanket Capitol Hill in their quest for legislative favors and sue at the drop of a hat to overturn government policies they don't like.
Their latest effort focuses on the Clean Power Plan, which sets the first-ever federal carbon pollution limits for our nation's electric power plants. It is a vital, common-sense safeguard that will greatly reduce the U.S.'s largest source of carbon emissions.
August 3 marks the one-year anniversary of the Clean Power Plan's unveiling. The plan rests on a solid legal and factual foundation, but the coal industry and its allies have been attacking it relentlessly with misguided lawsuits. I have joined a team of attorneys working to defend the Clean Power Plan—and on Tuesday, September 27, the plan will finally have its day in court, in the U.S. Court of Appeals for the District of Columbia Circuit.
For me, the Clean Power Plan isn't just an abstraction. At my apartment building, renewable energy is real. We have the largest residential solar energy installation in Washington, D.C. This isn't just a photo of a solar panel that might be built somewhere, someday: Instead, these panels are installed and operating, creating energy for myself and my neighbors.
The clean energy genie is already out of the bottle, in the form of technologies that dramatically cut carbon pollution. With every passing year, the need for those pollution cuts grows more urgent, as unprecedented warming continues to threaten our health and environment. Like communities around the nation, Washington, D.C., is at risk from a warming climate. Our beloved National Mall and other downtown areas are located on the coastal plain, making them vulnerable to sea level rise. A storm several years ago damaged several important D.C. buildings, including the National Archives where we keep many of our nation's most precious historical documents. The Army Corps of Engineers has built a levee south of the White House in an effort to keep floods at bay.
So there's no time to lose—the Clean Power Plan and its common-sense cuts in carbon pollution must be allowed to take effect. We simply can't let fossil fuel interests turn back the clock and prevent progress on the biggest environmental challenge of our time.
As I've seen through my time in the Nation's Capital, progress never happens if there aren't people willing to take a stand. Fortunately, most of us recognize the need to move decisively away from carbon pollution and toward clean energy. Among those vigorously defending the Clean Power Plan are state, county and municipal governments; forward-thinking power companies; renewable energy producers; companies that specialize in helping businesses and consumers save energy; and public health and environmental groups.
Misguided fossil fuel interests cannot and must not succeed. I believe we can successfully push back on them once again.
