In the 1990s, the number of juveniles in prison rapidly increased after a study came out called “The Superpredator Script,” which described a new breed of young criminals who needed to be treated as adults. Today, there are about 250,000 American children tried as adults per year. “The United States is the only country other than Somalia that sentences kids to die in prison,” says the founder of the Anti-Recidivism Coalition, Scott Budnick (who also produced the Hangover movie franchise). In this video, he discusses the consequences of trying juvenile offenders as adults and the need for nationwide reform.
If you want to win new work from new clients (new-new business), where do you start? The days of cold calling and persistence being effective tactics are long gone. Today's new business relationships need to be fostered in much the same way you'd start and nurture a personal relationship. You don't walk up to a complete stranger and ask them to marry you. So why would you do the same with a potential client?
Your approach should be to draw your new client towards you, before you start to approach them. If two people are moving towards each other, they are more likely to keep going and close the gap. They also meet as equals. When one person pursues another, on the other hand, this can set that person running in the same direction. The chase is energy sapping for both parties. It also risks putting the balance of power in any conversation in the hands of the person being chased, which is not good for the agency.
So how do you draw your new-new clients-to-be to you? There is a path that you could follow called Know, Like, Trust and Buy. Here are the stages, described briefly, with some actions that build your credibility at each stage and could move you to the next.
Stage 1: Know. Your clients-to-be need to get to know you. This step should be made gradually, consistently, memorably and be relevant to your clients. Ask, “What do my clients need to know for them?” They're not looking for a new agency so the things about you are less important. What would be useful to them? And of all of that, what is the link to you and what you do? What matters to your client? What matters to you? And where do they intersect?
Actions: Do some research and gather your answers to the above questions. What is going on in the sector? Who could you ask? What do you think about this? Turn your thinking into a regular newsletter or blog to send to your clients-to-be. Give it a name, and a brand. Focus it solely on them and their interests and concerns.
Stage 2: Like. Your clients-to-be start to like you. How do we get to like someone? We feel they have empathy with our situation. And us with theirs. We feel that they “get us”. They understand what's going on in our world. And what they say or show us is useful to us. How do you enable your client to learn something new about themselves, their sector?
Actions: Notice what is happening with your communication. Is there some evidence that your readers are liking what you are writing? If you use a trackable delivery system for your email you will be able to see who is starting to warm to you. Join a LinkedIn group where your client community gathers. Post a link to your piece along with a question. Send those people who open your communication a short thank you note and a bonus item.
Stage 3: Trust. Your clients-to-be start to trust you. This is a big move and the phase where you start to share more of you. There is likely to be some sort of personal contact, some sort of investment by you in the relationship. You might look to meet them at an event. Or you could invite them to an event that you are putting on, or attending around a theme of interest to them. There could be a telephone meeting. But this is not the opportunity for you to pitch or to pour on how brilliant you are. This is still about, building the relationship, inviting your client to talk, asking them “What do you think and what matters to you?” This is about being true and authentic to how you have communicated to this point. And then taking it to a personal level.
Stage 4: Buy. This may start to happen when you've done all of the above. And this is where you get the chance to demonstrate more overtly what you can do. This is where you will need to make sure that all of your evidence of past capability and process is ready to ensure that your approach pays off.
It can take a while to get to the buy stage because clients are people. They are not “buying decisions” or “budgets”. Any more than you are “someone who draws for a living” or a “computer operator”. This approach requires patience. When the opportunity to talk about you comes, you need to be ready, know what you are about and have a sound process in place to prepare and deliver a great presentation. If you've done the hard work to build the relationship to this point, you will have laid the foundations for proving that you're the partner they need.

This week, Somerset House opened a new show dedicated to Icelandic songwriter Björk, using virtual reality and 360° video to trap the viewer within an immersive, musical experience.
While there are a few clunky, transitional phases to the exhibition moving between rooms, sitting down and scrambling around with headsets and earphones the show is an impressive depiction of how combining emotive music and inventive technology can create very powerful viewer experiences.
The show mainly focuses on songs from the musician's latest album Vulnicura, providing visitors with 3D music videos depicting Björk herself in both human form and as a strange, digital creature.
It's certainly an exhibition for Björk-lovers, but will also be inspiring and exciting for anybody interested in the latest applications of virtual and augmented reality, and 360° panoramic film.
Björk Digital runs at Somerset house until 23 October, and tickets are £15, or £12.50 concessions.
Alcopop brand WKD, known for its luminous colours and sugary sweetness, was redesigned by consultancy JKR this week, taking on a new “fun, exciting” concept.
The new look sees the brand ditch its embossed lettering for a cleaner typeface, coupled with a new exclamation mark motif, which looks to better align itself with its predominately 18-to-24-year-old audience.
The typography used is also transparent, allowing it to be used as a device for various “oil-painting-inspired” patterns, according to JKR. The bottles' caps also include a series of 1990s instant messaging-inspired emoticon motifs, which JKR says aims to increase the element of fun, but we assume also hopes to inspire some nostalgia in the brand's millennial drinkers.
The redesigned bottles will roll out with a range of four flavours in October, and with two low-calorie variants by the end of the year.
Furniture giant Ikea turned their hand to cookery this week, with a new dining space.
The pop-up Dining Club has been designed by Ikea's in-house team, and will open in London's Shoreditch on 10 September, and will be free for diners.
In typical Ikea fashion, the food's coming flatpacked diners will be able to attend masterclasses on topics such as Swedish Baking and Clean Eating, and will make their own meals.
The concept is based on encouraging people to spend time together through cooking and eating, Ikea says.
You can find out more about the dining experience here.
It was announced this week that the Channel 4 visual identity, the cover art for David Bowie's final album Blackstar and the Dreamland Margate theme park are all in the running for this year's Design Museum awards.

The post 5 important things that happened in design this week appeared first on Design Week.
Consultancy PWW has developed pharmaceutical company GlaxoSmithKline's (GSK) new research and development facility, Immersive Intelligent Manufacturing.
The new 697m2 “smart space” is designed to demonstrate how “state-of-the-art systems and technologies can be combined in a manufacturing line and environment”, according to the consultancy.
The IIM facility is being used to accelerate technology adoption within GSK, and includes internal and external spaces that are interconnected. The “sandpit”, for instance, encompasses workshops, manufacturing and collaboration areas.
Other design features include a changing room complete with augmented reality lab attire instruction and compliance, which indicates whether the user is dressed correctly or not.
Colour has been used to improve the functionality of the facility by identifying different areas within it, as well as being incorporated in the signage, graphics and user interfaces.
PKK's design allows for flexible use of the facility, which is considered necessary due to the range of outputs and research carried out there.
Remote working is also possible through the use of technology that helps to control and visualise the manufacturing data.
Head of GSK's IIM project, Patrick Hyett, says: “We wanted to build a facility we can point to and show the art of the possible.”

Somerset House prides itself on its photography exhibitions but those expecting to see anything two-dimensional within the gallery's latest show will be in for a surprise.
Björk Digital is an exploration of songwriter Björk's 2015 album Vulnicura, using virtual and augmented reality, 360° video, soundscaping and cinema to create an immersive and emotionally stimulating experience.
The exhibition space is split up into eight rooms, each presenting a different virtual environment either through screens or headsets, from an Icelandic landscape to a cosmic view of the universe.
At the centre of each experience is Björk herself, either represented through film in human form, as a virtual creature or even as a body part, as one gruesome piece shows.
While this might seem a little egocentric, there's a point to it the exhibition's use of interactive technology forces viewers to become part of the singer's tormented story. Visitors don't walk around the space surrounded by other people, but are instead trapped in a box with the singer alone.
This turns the exhibition into a deeply personal performance, helping viewers better understand the singer's own emotions throughout the album, from heartache to anger, as Björk herself explains.
“There is something about the 360° staging which is very theatrical and dramatic,” she says. “When you put those goggles on your face, you're in a very theatrical world. As heartbreak is the oldest story there is, I felt it could take this sort of experimentation.”
At the start of the exhibition, visitors enter a room lined with two panoramic screens on opposite walls, playing a short film called Black Lake, which features a distressed Björk strewn across a rocky, volcanic landscape in Iceland. The film, originally commissioned by New York's Museum of Modern Art, is a gentle lull into the more enveloping, solitary experiences which follow.
One of the loneliest and most affecting performances of the show is Stonemilker VR, a lengthy nine-minute-long 360° music video, which disorientates the viewer as they wobblingly swivel round on a stool with a headset on to capture Björk as she circles them against a beach landscape.
Things get a lot weirder with Mouthmantra VR, a headset experience filmed from the inside of the musician's mouth, with teeth, tongue and tonsils twirling in full view as she sings.
Stranger still is Notget VR, directed by Warren Du Preez and Nick Thornton Jones, which sees Björk transform into a bizarre, moth-like creature. The piece requires users to stand rather than sit, allowing you to come within inches of Björk's perturbing, computerised form (or, more likely, back away).
While the majority of exhibits are ready-made interactive experiences packaged up for the audience, the Biophilia space is a more educational platform which lets users select their own journey through an iPad, experiencing different music, visuals, and explore different technologies and musical instruments used within Björk's work.
In fitting fashion with the rest of the show, Björk revealed herself at the private view of the exhibition in digital form. Through the use of a motion capture suit and streaming technology, she appeared on a projection screen as a spacey avatar which mimicked her movements, able to interact with the audience and answer questions.
While seeing Björk in the flesh or simply via video stream might have also done the job, this avatar was a scary demonstration of the growing capability of immersive technology, mirrored throughout the rest of the exhibition.
The show is an eclectic mix some of the digital installations set within a cosmic environment are far removed from reality, while the 360° films trap the viewer within a very real-life world. But all of them prove how, while music and film can be very affecting on their own, technology can enhance and attack a viewer's senses. Björk Digital shows that isolating people within a virtual, non-real environment can ironically incite a lot of real, human emotion.
Björk Digital runs until 23 October 2016 at New Wing, Somerset House, Strand, London WC2R 1LA. Tickets are £15, or £12.50 concessions.

It's always there. The latest achingly cool project you've stumbled upon in this crowded creative industry of ours, confronting your confidence, making you feel like you need to tailor your own work according to what is cool and what you think they would want to see in a portfolio.
Then there's a moment when it becomes apparent that you've lost your creative identity and strayed away from those college dreams, directionless and disillusioned. That's where I found myself six months after graduation.
Unless you're very fortunate, making money is essential. I did my fair share of drawing faceless people in suits climbing ladders into money trees among other tired conceptual illustrations for early clients with the best intentions and decent budgets.
I held dear to my trust that they would be temporary, earning me the money to transition away from employment towards freelancing as an illustrator where I could be more effective in shaping my own destiny. The jobs that I really desired started to arrive when people saw my personal work, the stuff that is so easily abandoned in the face of fat salaries, trends, mortgages and that TV package.
The world is littered with examples of landmark projects born of expressions of individual experiences, drawing on the world around us. The Office was the product of Stephen Merchant and Ricky Gervais' comedic study on the world of middle management and one of the most successful self-initiated projects of all time.
I felt a tremendous sense of wonder as a seventeen year old, when Gorillaz arrived on the scene. Seeing what Jamie Hewlett and Damon Albarn had created made me yearn for the same belonging to something that I loved to do and was my own, despite having no clue where to begin. Some may have called that a fantasy for the young and naïve, but isn't that why we all wished to get into the creative industry in the first place?
I felt the same glowing feeling, a year removed from education, thanks to the roaring laughter in my shared studio when I presented a new illustration, featuring a boxing poster pitting Barack Obama against Hilary Clinton in what I called The Race v Sex Challenge. This was my way of expressing the dismay I felt with the media's persistent focus on the gender or Hilary and the skin colour of Barack.
It was in a meeting with the then design director of The Guardian, that my eyes were opened to the benefits of personal work. Flicking through my portfolio, featuring only one commissioned piece of work and 24 pages of self-initiated pieces, he stopped on The Race Sex challenge and told me that my angle on current affairs was different, funny and interesting. The self-initiated football work I created to show my knowledge was flagged as valuable too. To my surprise, I was working for The Guardian within a couple of months, despite an overwhelming competition field and vast inexperience.
After that, only the commissioned work I enjoyed creating made the portfolio, while many jobs that provided nothing more than money were ruthlessly omitted to avoid attracting similar jobs with no creative benefit. Over 50% of the portfolio were works I had self-initiated, just like the Race v Sex Challenge.
On episode 25 of my Arrest All Mimics podcast, creative agency Human After All discuss how Little White Lies started as a university project and ultimately brought in work for the BAFTAs.
I won my first job outside of editorial illustration, working on a Channel 4 television trailer for season 3 of Skins. A chance meeting with a director from the TV station led him to Tyson v Thatcher, a follow on from The Race Sex Challenge. He found the piece hilarious, daring and saw a playfulness and energy in the work that he felt Skins was crying out for.
The Skins work continued for three years, brought me great creative pleasure and elevated my name, bringing me positive press and other jobs in new fields. Now, with eight years experience, I continue to play, to explore new ideas and harness that precious asset we all possess which is a unique journey.
Client work is wonderful and essential, but it is the work we create simply because we want to, out of some deep-rooted necessity owed only to ourselves that embodies the truly refreshing and qualities most likely to attract the work we dream about at college.
Personal connects with a greater number of people while trends are forgotten very fast. The portfolio, no matter the discipline, is not just a showcase of what you've done or can do, but more importantly, has to be a statement of intent, packed with the ideas, honesty, oddity and originality found only in you.

We asked you for images of modernist American architecture. From Chicago concrete to Palm Spring aesthetics, here is what you've discovered
I took this photo during a three month sabbatical spent across Japan and America. Chicago was our final port of call before flying home, and the architecture we saw there was an unexpected surprise and a delight. I hadn't realised the ‘corncob' towers were even in Chicago, though I recognised them from Wilco's “Yankee, Hotel Foxtrot” album cover. I took the photo from the Chicago river as we sailed past on an architecture tour boat. The guide explained how they were part of a wonderful utopian idea to have homes, parking, shops, an auditorium, offices and a marina all in one place to encourage Chicagoans to move back downtown. Hence their name Marina Towers.

Few will be surprised to learn that Björk admits she can be something of a control freak when it comes to her musical output.

Scientists have discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture.
New discoveries coming from the study of exoplanetary systems will show us where on the continuum of ordinary to unique our own Solar System's layout falls. So far, planet hunters have revealed populations of planets that are very different from what we see in our Solar System. The most-common exoplanets detected are so-called super-Earths, which are larger than our planet but smaller than Neptune or Uranus. Given current statistics, Jupiter-sized planets seem fairly rare--having been detected only around a small percentage of stars.
This is of interest because Jupiter's gravitational pull was likely a huge influence on our Solar System's architecture during its formative period. So the scarcity of Jupiter-like planets could explain why our home system is different from all the others found to date.
The new discovery from the Carnegie team is the first exoplanet detection made based solely on data from the Planet Finder Spectrograph--developed by Carnegie scientists and mounted on the Magellan Clay Telescopes at Carnegie's Las Campanas Observatory, shown at top of page. PFS is able to find large planets with long-duration orbits or orbits that are very elliptical rather than circular, including the new trio of planets discovered in this `"twin'" star study. This special capability comes from the long observing baseline of PFS; it has been taking observations for six years.
Led by Johanna Teske, the team included a number of Carnegie scientists from both the Department of Terrestrial Magnetism in Washington, DC, and the Carnegie Observatories in Pasadena, CA, as well as Steve Vogt of the University of California Santa Cruz.
"We are trying to figure out if giant planets like Jupiter often have long and, or eccentric orbits," Teske explained. "If this is the case, it would be an important clue to figuring out the process by which our Solar System formed, and might help us understand where habitable planets are likely to be found."
The twin stars studied by the group are called HD 133131A and HD 133131B. The former hosts two moderately eccentric planets, one of which is, at a minimum, about 1 and a half times Jupiter's mass and the other of which is, at a minimum, just over half Jupiter's mass. The latter hosts one moderately eccentric planet with a mass at least 2.5 times Jupiter's.
The two stars themselves are separated by only 360 astronomical units (AU). One AU is the distance between the Earth and the Sun. This is extremely close for twin stars with detected planets orbiting the individual stars. The next-closest binary system that hosts planets is comprised of two stars that are about 1,000 AU apart.
The system is even more unusual because both stars are "metal poor," meaning that most of their mass is hydrogen and helium, as opposed to other elements like iron or oxygen. Most stars that host giant planets are "metal rich." Only six other metal-poor binary star systems with exoplanets have ever been found, making this discovery especially intriguing.
Adding to the intrigue, Teske used very precise analysis to reveal that the stars are not actually identical "twins" as previously thought, but have slightly different chemical compositions, making them more like the stellar equivalent of fraternal twins.
This could indicate that one star swallowed some baby planets early in its life, changing its composition slightly. Alternatively, the gravitational forces of the detected giant planets that remained may have had a strong effect on fully-formed small planets, flinging them in towards the star or out into space.
"The probability of finding a system with all these components was extremely small, so these results will serve as an important benchmark for understanding planet formation, especially in binary systems," Teske explained.

In a video uploaded to YouTube on August 3rd (below), engineers from the Russian space agency, Roscosmos, proposed an orbiter and lander mission to Ganymede. The video suggests a launch could come in the next decade. Although the commentary is in Russian, the video appears to suggest that Ganymede may be as good a candidate or better for life than Europa.
In March of 2015, NASA's Hubble Space Telescope revealed the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search for life, as we know it.
"This discovery marks a significant milestone, highlighting what only Hubble can accomplish," said John Grunsfeld, recently retired assistant administrator of NASA's Science Mission Directorate at NASA Headquarters. "In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth."
Ganymede is the largest moon in our solar system and the only moon with its own magnetic field, shown above. The magnetic field causes aurorae, which are ribbons of glowing, hot electrified gas, in regions circling the north and south poles of the moon. Because Ganymede is close to Jupiter, it is also embedded in Jupiter's magnetic field. When Jupiter's magnetic field changes, the aurorae on Ganymede also change, "rocking" back and forth.
By watching the rocking motion of the two aurorae, scientists were able to determine that a large amount of saltwater exists beneath Ganymede's crust, affecting its magnetic field.
A team of scientists led by Joachim Saur of the University of Cologne in Germany came up with the idea of using Hubble to learn more about the inside of the moon. "I was always brainstorming how we could use a telescope in other ways," said Saur. "Is there a way you could use a telescope to look inside a planetary body? Then I thought, the aurorae! Because aurorae are controlled by the magnetic field, if you observe the aurorae in an appropriate way, you learn something about the magnetic field. If you know the magnetic field, then you know something about the moon's interior."
If a saltwater ocean were present, Jupiter's magnetic field would create a secondary magnetic field in the ocean that would counter Jupiter's field. This "magnetic friction" would suppress the rocking of the aurorae. This ocean fights Jupiter's magnetic field so strongly that it reduces the rocking of the aurorae to 2 degrees, instead of 6 degrees if the ocean were not present. Scientists estimate the ocean is 60 miles (100 kilometers) thick -- 10 times deeper than Earth's oceans -- and is buried under a 95-mile (150-kilometer) crust of mostly ice.
Scientists first suspected an ocean in Ganymede in the 1970s, based on models of the large moon. NASA's Galileo mission measured Ganymede's magnetic field in 2002, providing the first evidence supporting those suspicions. The Galileo spacecraft took brief "snapshot" measurements of the magnetic field in 20-minute intervals, but its observations were too brief to distinctly catch the cyclical rocking of the ocean's secondary magnetic field.
The new observations were done in ultraviolet light and could only be accomplished with a space telescope high above Earth's atmosphere, which blocks most ultraviolet light.

In a newly melted part of Greenland, Australian scientists found the leftover structure from a community of microbes that lived on an ancient seafloor, according to a study in Wednesday's journal Nature. The team have found what they think is the oldest fossil on Earth, a remnant of life from 3.7 billion years ago when Earth's skies were orange and its oceans green.
The discovery shows life may have formed quicker and easier than once thought, about half a billion years after Earth formed . And that may also give hope for life forming elsewhere, such as Mars, said study co-author Martin VanKranendonk of the University of New South Wales and director of the Australian Center for Astrobiology.
"It gives us an idea how our planet evolved and how life gained a foothold," VanKranendonk said.
"It would have been a very different world. It would have had black continents, a green ocean with orange skies," he said. The land was likely black because the cooling lava had no plants, while large amounts of iron made the oceans green. Because the atmosphere had very little oxygen and oxygen is what makes the sky blue, its predominant color would have been orange, he said.
Scientists had thought it would take at least half a billion years for life to form after the molten Earth started to cool a bit, but this shows it could have happened quicker, he said. That's because the newly found fossil is far too complex to have developed soon after the planet's first life forms, he said.
In an outcrop of rocks that used to be covered with ice and snow which melted after an exceptionally warm spring, the Australian team found stromatolites (shown at top of the page surviving in Antarctica), which are intricately layered microscopic layered structures that are often produced by a community of microbes. The stromatolites were about .4 to 1.6 inches high (1 to 4 centimeters).
It "is like the house left behind made by the microbes," VanKranendonk said.
Scientists used the layers of ash from volcanoes and tiny zircon with uranium and lead to date this back 3.7 billion years ago, using a standard dating method, VanKranendonk said.

The dating seems about right, said Abigail Allwood , a NASA astrobiologist who found the previous oldest fossil, from 3.48 billion years ago, in Australia. But Allwood said she is not completely convinced that what VanKranendonk's team found once was alive. She said the evidence wasn't conclusive enough that it was life and not a geologic quirk.
"It would be nice to have more evidence, but in these rocks that's a lot to ask," Allwood said in an email.

"Ten billion years ago, galaxies like our Milky Way were much smaller, but they were forming stars 30 times faster than they are today," said Casey Papovich of Texas A&M University.
An international team of astronomers has charted the rise and fall of galaxies over 90 percent of cosmic history. Their work, which includes some of the most sensitive astronomical measurements made to date, is published by The Astrophysical Journal.
The FourStar Galaxy Evolution Survey (ZFOURGE) has built a multicolored photo album of galaxies as they grow from their faint beginnings into mature and majestic giants. They did so by measuring distances and brightnesses for more than 70,000 galaxies spanning more than 12 billion years of cosmic time, revealing the breadth of galactic diversity.
The team assembled the colorful photo album by using a new set of filters that are sensitive to infrared light and taking images with them with the FourStar camera at Carnegie's 6.5-meter Baade Telescope at our Las Campanas Observatory in Chile. They took the images over a period of 45 nights. The team made a 3-D map by collecting light from over 70,000 galaxies, peering all the way into the distant universe, and by using this light to measure how far these galaxies are from our own Milky Way.
The deep 3-D map also revealed young galaxies that existed as early as 12.5 billion years ago (at less than 10 percent of the current universe age), only a handful of which had previously been found. This should help astronomers better understand the universe's earliest days.
"Perhaps the most surprising result is that galaxies in the young universe appear as diverse as they are today," when the universe is older and much more evolved, said lead author Caroline Straatman, a recent graduate of Leiden University. "The fact that we see young galaxies in the distant universe that have already shut down star formation is remarkable."
But it's not just about distant galaxies; the information gathered by ZFOURGE is also giving the scientists the best-yet view of what our own galaxy was like in its youth.
"ZFOURGE is providing us with a highly complete and reliable census of the evolving galaxy population, and is already helping us to address questions like: How did galaxies grow with time? When did they form their stars and develop into the spectacular structures that we see in the present-day universe?" added Ryan Quadri, also of Texas A&M.
In the study's first images, the team found one of the earliest examples of a galaxy cluster, a so-called "galaxy city" made up of a dense concentration of galaxies, which formed when the universe was only three billion years old, as compared to the nearly 14 billion years it is today.
"The combination of FourStar, the special filters, Magellan, and the conditions at Las Campanas led to the detection of the cluster," said Persson, who built the FourStar instrument at the Carnegie Observatories in Pasadena. "It was in a very well-studied region of the sky--'hiding in plain sight.'"
The paper marks the completion of the ZFOURGE survey and the public release of the dataset, which can be found here: http://zfourge.tamu.edu/DR2016/data.html.

This week, the ExoMars mission control team at ESA's centre in Darmstadt, Germany, is training to prepare for next month's arrival at the Red Planet.
Under the watchful eye of Flight Operations Director Michel Denis, the team was taken through a series of realistic simulations that rehearsed both ‘nominal' when everything goes as planned and ‘contingency' the opposite situations.
The team is actually a ‘team of teams' a number of spacecraft operations engineers working under the spacecraft operations manager, supported by diverse specialists from areas including flight dynamics, ground station operations, software and network support, and simulations and training as well as the ExoMars team from ESA's technical centre in the Netherlands.
Teams from the builder of the Mars orbiter, Thales Alenia Space France, and the builder of the Schiaparelli lander, Thales Alenia Space Italy, also took part in the ‘sim'.
Today, ExoMars has completed 80% of the 500 million km trip to Mars, and is 121 566 000 km from Earth. Schiaparelli is set to separate from its parent craft on 16 October and, three days later, will land on Mars as the orbiter fires its main engine to begin circling the planet.

"AlphaGo is not only a milestone in the quest of AI, but also an indication that IT now has entered a new era," said Fei-YueWang, at the Chinese Academy of Sciences and secretary general of the Chinese Association of Automation. The computer's win signaled a significant evolution of information technology (IT) and artificial intelligence (AI), according Wang, a professor at the Chinese Academy of Sciences. As the result, IT is no longer information or industrial technology, the New IT is Intelligent Technology. The world has entered the fifth era of intelligent technology.
The world's oldest board game still has a few moves to play. Go, a game of strategy and instinct considered more difficult to master than chess, was created roughly in the same era as the written word. The game is uniquely human - or, it was. Last year, a computer program called AlphaGo defeated an internationally ranked professional player.
In a recent editorial published in the IEEE/CAA Journal of Automatica Sinica, Wang argues that core principles of automation and Al must be rethought as the world navigates an IT paradigm shift.
Wang sketches the progress of robotic and neural machine-human interaction in a timeline of five "control" eras. Automation evolved from the pure mechanics of ancient water clocks and steam engines to the eventual development of electric circuits and transfer functions that gave way to power grids. Digital computers and microprocessors signaled the third shift and paved the way for the fourth - the Internet and the World Wide Web.
In the first four controls, physical and mental realities were approximated as accurately as possible and adjusted through the use of dual control theory. A machine with a set of conditions and a goal could succeed or fail. As the machine acts, it also investigates to learn what action may result in a better future outcome.
Between the physical and mental spaces, another reality in need of double control exists. Augmented, or artificial, reality bridges the gap of actuality and imagination. Pokémon GO is a prime example, as people navigate the physical world to find fictional creatures with only experience as a guide. The parameters and goals shift with each new exposure.
"In Control 5.0...only association revealed by data or experience is available, and causality is a luxury that is no longer attainable with limited resources for uncertainty, diversity, and complexity," Wang said.
Recognition of all three worlds and the dual learning roles of each, according to Wang, will be essential in the fifth era of intelligent technology.

If humanity is to survive beyond the lifetime of our Sun, we must leave our Solar System and travel to the stars. If Proxima b is habitable, then it might be an ideal place to move. Perhaps we have just discovered a future home for humanity! But in order to know for sure, we must make many more observations, run many more computer simulations, and, hopefully, send probes to perform the first direct reconnaissance of an exoplanet. The challenges are huge, but Proxima offers a bounty of possibilities that fills me with wonder. Whether habitable or not, Proxima b offers a new glimpse into how planets and life fit into our universe.
The discovery of Proxima b is the biggest exoplanet discovery since the discovery of exoplanets. The planet is not much bigger than Earth and resides in the “habitable zone” of the Sun's nearest stellar neighbor. This planet may represent humanity's best chance to search for life among the stars. But is Proxima b habitable? Is it inhabited? These questions are impossible to answer at this time because we know so little about the planet. However, we can extrapolate from the worlds of our Solar System, as well as employ theoretical models of galactic, stellar, and planetary evolution, to piece together realistic scenarios for Proxima b's history.
The possibilities are varied and depend on phenomena usually studied by scientists in fields that are considered distinct, but an integrated perspective — an astrobiological perspective — can provide a realistic assessment of the possibility that life could have arisen and survived on the closest exoplanet.
As an astrobiologist and astronomer at the University of Washington, and a member of NASA's Virtual Planetary Lab, Roy Barnes has investigated the habitability of planets orbiting red dwarfs for years. His research involves building computer models that simulate how planetary interiors and atmospheres evolve, how stars change with time, and how planetary orbits vary. The discovery of Proxima b has me very excited, but being Earth-sized and in the habitable zone are just the first two requirements for a planet to support life, and the list of requirements is much longer for planets orbiting red dwarfs than for stars like our Sun.
If Proxima b is in fact habitable, meaning it possesses liquid water or even inhabited, meaning life is currently present, then it will have traversed a very different evolutionary path than Earth. This difference is frustrating, in that it will make our initial interpretations challenging, but also exciting, as it offers the chance to learn how Earth-sized planets evolve in our universe. Whether Proxima b is a sterile wasteland or teeming with life, we are now embarking on an unprecedented era of discovery, one that may finally provide an answer that age-old question “Are we alone?”.
What to make of Proxima b? It is at least as massive as Earth, and may be several times more massive. Its “year” is just over 11 days and its orbit may be circular or significantly elongated. Its host star is only 12% as massive as our Sun, 0.1% as bright, and it is known to flare. It may be joined to the stars Alpha Centauri A and B, 15,000 astronomical units (AU) away, by their mutual gravitational attraction.
All three stars contain substantially more heavy elements than our Sun, but we know very little of the composition of Proxima b, or how it formed. The new data point toward the presence of a second planet orbiting in the system with a period near 200 days, but its existence cannot be proven at this time. These are the facts we have and from them we must deduce whether Proxima b supports life.
Proxima b was detected via the radial velocity method, which does not provide a direct measurement of the planet's mass, only a minimum mass. So, the first question we'd like to answer is whether the planet's mass is low enough to be rocky like Earth. If the planet is much larger, it may be more like Neptune with a thick gaseous envelope. While we don't know where the dividing line between rocky and gaseous exoplanets is, models of planet formation and analyses of Kepler planets suggest the transition is between 5 and 10 times the mass of Earth. Only about 5% of allowed orbits place Proxima b's mass above 5 Earth masses, so it is very likely that this planet is in the rocky range.
The next question to ask is if the planet actually formed with water. Water consists of hydrogen and oxygen, the first and third most common elements in the galaxy, so we should expect it to be everywhere. Close to stars, however, where Proxima b resides, water is heated into its vapor phase while planets are forming, and hence it is difficult for planets to capture it. Planets that form at larger distances can gather more water, so if Proxima b formed farther out and moved to its current orbit later, it is more likely to be water-rich.
At this time, we don't know how the planet formed, but three scenarios seem most probable: 1) the planet formed where it is from mostly local material; 2) the planet formed farther out while the gas and dust disk that birthed the planetary system still existed, and forces from that disk drove the planet in to its present orbit; or 3) the planet formed elsewhere and some sort of system-wide instability rearranged the planets and b ultimately arrived in its current orbit.
The first method is how Earth and Venus formed, and so Proxima b may or may not possess significant water if it formed in this way. The second method produces planets that are very water-rich because water is more likely to be in its ice phase farther out in the disk and so the forming planet could easily gather it up. The third method is inconclusive as the planet could have come from an interior orbit and formed without water or farther out and be water-rich. We conclude that it is entirely possible that this planet has water, but we cannot be certain.
Next let's consider the clues from the stars themselves. Computer models of the evolution of our galaxy suggest that stars enriched in heavy elements like Proxima cannot form locally (25,000 light-years from the galactic center) as there just aren't enough heavy elements available. But closer to the galactic center, where star formation has been more vigorous and transpiring for longer, stars like Proxima are possible. Recent work has found that stars in our local solar neighborhood with compositions like Proxima must have formed at least 10,000 light-years closer to the galactic center. It would seem Proxima Centauri has wandered through our galaxy and this history may have played an important role in the evolution of Proxima b.
Computer models of the evolution of the Milky Way galaxy suggest Proxima Centauri has moved outward at least 10,000 light-years from where it formed, shown by the orange circle. The Sun and Earth probably formed near where they orbit today (blue circle), which is where we find Proxima Centauri, too.
The orbit of Proxima around Alpha Centauri A and B, assuming they are gravitationally connected, is large compared to other multiple star systems. In fact, it is so large that A and B's hold on Proxima is weak and the effects of the Milky Way galaxy have shaped Proxima's orbit significantly. The mass of the Milky Way as a whole causes Proxima's orbit to vary both in shape and orientation continuously.
Proxima is also susceptible to gravitational encounters from passing stars that can change its orbit. Recent simulations by Nate Kaib have found that these two effects can often lead to close passages between the stars in a multiple star system that disrupt their planetary systems. The disruption is often powerful enough to eject planets from the system and completely rearrange the orbits of the planets that remain.
New simulations by Russell Deitrick are revealing that this scenario is a real concern for Proxima, too; there is a significant probability that at some point in the past, Proxima swooped in close enough to Alpha Centauri A and B to cause its planetary system to break apart, hurling Proxima b's siblings into deep space. If such a disruption occurred, Proxima b may not have formed where we find it today because its orbit would have been affected by this disruption.
Even if Proxima is not currently bound to Alpha Cen A and B, it appears to be travelling with them, and it is very likely the stars formed from the same cloud of dust and gas. If they formed together, they should have similar compositions and nearly identical ages. Connecting their ages is important because it is very difficult to measure the ages of low mass stars like Proxima Centauri. Astronomers can estimate the age of Alpha Cen A via asteroseismology, the study of “starquakes.”
Stars bigger than the Sun vibrate with large enough amplitudes that brightness fluctuations can be observed, and careful monitoring of the pulsations can reveal a star's age. Recent work by Dr. Michaël Bazot has found that Alpha Cen A is between 3.5 and 6 billion years old. This range is larger than we would like, but Proxima is certainly old enough to support life, and Proxima b might even be about the same age as Earth!
Next we turn to clues from the Proxima Centauri planetary system. The vast majority of the energy used by life on Earth comes from our Sun, and small stars like Proxima can produce energy for trillions of years. The host star is almost as small as stars come, so for a planet to receive as much stellar energy as Earth, Proxima b must be about 25 times closer in than Earth is from the sun. This distance is where the habitable zone lies.
While Proxima is much dimmer than the Sun, it is still a thermonuclear explosion, and, everything else equal, life seems more likely at larger distances. And indeed the close-in orbit does produce numerous obstacles that life on Earth did not have to overcome. These include a long formation time for the star, short and energetic bursts of energy in UV and X-ray light, strong magnetic fields, larger starspots, larger coronal mass ejections, and gravitational tidal effects that cause rotational properties to change and frictional heating in oceans (if they exist) and the rocky interior.
The history of Proxima's brightness evolution has been slow and complicated. Stellar evolution models all predict that for the first one billion years Proxima slowly dimmed to its current brightness, which implies that for about the first quarter of a billion years, Proxima b's surface would have been too hot for Earth-like conditions. As Rodrigo Luger and Barnes recently showed, had our modern Earth been placed in such a situation, it would have become a Venus-like world, in a runaway greenhouse state that can destroy all of the planet's primordial water. This desiccation can occur because the molecular bonds between hydrogen and oxygen in water can be destroyed in the upper atmosphere by radiation from the star, and hydrogen, being the lightest of the elements, can escape the planet's gravity. Without hydrogen, there can be no water, and the planet is not habitable. Escaping or avoiding this early runaway greenhouse is the biggest hurdle for Proxima b's chances for supporting life.
Figure 2: Proxima Centauri's habitable zone has moved inward since it formed, which may mean that planet b lost its water shortly after it formed, when the system was 1—10 million years old. The habitable zone, shown in blue, doesn't arrive at the orbit of planet b until almost 200 million years after it formed. This early brightness may be the biggest obstacle for life to have gained a foothold on Proxima Centauri b.
As the star dims, the water destruction process halts, and so total desiccation is not inevitable. If some water remains, the atmosphere may also contain large quantities of oxygen leftover from the water vapor destruction. While having large amounts of water and oxygen may sound like a good recipe for life, it almost certainly is not. Oxygen is one of the most reactive elements, and its presence in the young atmosphere of Proxima b would likely prevent the development of pre-biotic molecules that require conditions with little oxygen to form. Life on Earth formed when no oxygen was present, and photosynthesis ultimately produced enough oxygen for it to become a major component of our atmosphere. Note that the destruction of only some water leads to the rather surprising possibility that the planet could possess oceans and an oxygen-rich atmosphere, but has been unable to support life!
Another intriguing possibility is that Proxima b started out more like Neptune and the early brightness and flaring eroded away a hydrogen-rich atmosphere to reveal a habitable Proxima below. Such a world was investigated by Rodrigo Luger, Barnes and others, and was found to be a viable pathway to avoid total desiccation. Essentially the hydrogen atmosphere protects the water. If Proxima b formed with about 0.1-1% of its mass in a hydrogen envelope, the planet would lose the hydrogen but not its water, potentially emerging as a habitable world after the star reached its current brightness.
This wide range of possible evolutionary pathways presents a daunting challenge as we imagine using space- and ground-based telescopes to search for life in the atmosphere of Proxima b. Nearly all the components of an atmosphere imprint their presence in a spectrum, so with our knowledge of the possible histories of this planet, we can begin to develop instruments and plan observations that pinpoint the critical differences.
For example, at high enough pressures, oxygen molecules can momentarily bind to each other and produce an observable feature in a spectrum. Crucially, the pressures required to be detectable are large enough to discriminate between a planet with too much oxygen, and one with just the right amount for life. As we learn more about the planet and the system, we can build a library of possible spectra from which to quantitatively determine how likely it is that life exists on Proxima b.
While the early brightness of the host star is the biggest impediment to life, other issues are also important. One of the original concerns for the habitability of planets orbiting red dwarfs was that they would become “tidally locked”, meaning that one hemisphere permanently faces the host star. This state is similar to the rotation of our Moon, in which the same tidal forces that raise waves in our ocean have caused the Moon to show only one face to Earth. Because it is so close to its star, Proxima b may be in this state, depending on the shape of its orbit.
For decades, astronomers were concerned that such a tidally locked planet would be uninhabitable because they believed the atmosphere would freeze and collapse to the surface on the permanently dark side. That possibility is now viewed as very unlikely because winds in the atmosphere will transport energy around the planet and maintain sufficient warmth on the backside to prevent this freeze out. Thus, as far as atmospheric stability is concerned, tidal locking is not a concern for this planet's potential habitability.
Although tidal locking is not very dangerous for life, it is possible for tides to provide large amounts of energy to the planet's atmosphere and interior. This energy is often called “tidal heating” and is a result of the deformation of the planet due to changes in the host star's gravitational force across the planet's diameter. For example, if the planet is on an elliptical orbit, when it is closer to the star, it feels stronger gravity than when it is farther away. This variation will cause the shape of the planet to change, and this deformation can cause friction between layers in the planet's interior, producing heat.
In extreme cases, tidal heating could trigger the onset of a runaway greenhouse like the one that desiccated Venus, independent of starlight. Proxima b is not likely to be in that state, but the tidal heating could still be very strong, causing continual volcanic eruptions as on Jupiter's moon Io, and/or raising enormous ocean waves. Based on the information we have now, we don't know the magnitude of tidal heating, but we must be aware of it and explore its implications.
The host star's short, high energy bursts, called flares, are also a well known concern for surface life on planets of red dwarfs. Flares are eruptions from small regions of the surfaces of stars that cause brief (hours to days) increases in brightness. Crucially, flares emit blasts of positively-charged protons, which have been shown by Antigona Segura and colleagues to deplete ozone layers that can protect life from harmful high-energy UV light.
Proxima flares far more often than our Sun and Proxima b is much closer to Proxima than Earth is to the Sun, so Proxima b is likely to have been subjected to repeated bombardments. If the atmosphere could develop a robust shield to these eruptions, such as a strong magnetic field that then flaring could be unimportant. Alternatively if it exists under just a few meters of water. Therefore, flares should not be considered fatal for life on Proxima b.
The concern over flaring naturally leads to the question of whether the planet actually does have a protective magnetic field like Earth's. For years, many scientists were concerned that such magnetic fields would be unlikely on planets like Proxima b because tidal locking would prevent their formation. The thinking went that magnetic fields are generated by electric currents moving in the planetary core, and the movement of charged particles needed to create these currents was caused by planetary rotation. A slowly rotating world might not transport the charged particles in the core rapidly enough to generate a strong enough magnetic field to repel the flares, and hence planets in the habitable zones of M dwarfs have no atmospheres.
However, more recent research has shown that planetary magnetic fields are actually supported by convection, a process by which hot material at the center of the core rises, cools, and then returns. Rotation helps, but Dr. Peter Driscoll and I recently calculated that convection is more than sufficient to maintain a strong magnetic field for billions of years on a tidally locked and tidally heated planet. Thus, it is entirely possible that Proxima b has a strong magnetic field and can deflect flares.
So is Proxima b habitable? The short answer is “It's complicated.” Our observations are few, and what we do know allow for a dizzying array of possibilities. Did Proxima b move halfway across the galaxy? Did it endure a planetary-system-wide instability that launched its sibling planets into deep space and changed its orbit? How did it cope with the early high luminosity of its host star? What is it made of? Did it start out as a Neptune-like planet and then become Earth-like? Has it been relentlessly bombarded with flares and coronal mass ejections? Is it tidally heated into an Io-like (or worse) state? These questions are central to unlocking Proxima's potential habitability and determining if our nearest galactic neighbor is an inhospitable wasteland, an inhabited planet, or a future home for humanity.
The last point is not as rhetorical as it might seem. Since all life requires an energy source, it stands to reason that, in the long term — by which I mean the loooong term — planets like Proxima b might be the ideal homes for life. Our Sun will burn out in a mere 4 billion years, but Proxima Centauri will burn for 4 trillion more. Moreover, if a “planet c” exists and slightly perturbs b's orbit, tidal heating could supply modest energy to b's interior indefinitely, providing the power to maintain a stable atmosphere.

“This galaxy cluster isn't just remarkable for its distance, it's also going through an amazing growth spurt unlike any we've ever seen,” said Tao Wang of the French Alternative Energies and Atomic Energy Commission (CEA) who led the NASA study.
A new record for the most distant galaxy cluster has been set using NASA's Chandra X-ray Observatory and other telescopes. This galaxy cluster may have been caught right after birth, a brief, but important stage of evolution never seen before.
The galaxy cluster is called CL J1001+0220 (CL J1001 for short) and is located about 11.1 billion light years from Earth. The discovery of this object pushes back the formation time of galaxy clusters the largest structures in the Universe held together by gravity by about 700 million years.
The core of CL J1001 contains eleven massive galaxies nine of which are experiencing an impressive baby boom of stars. Specifically, stars are forming in the cluster's core at a rate that is equivalent to over 3,000 Suns forming per year, a remarkably high value for a galaxy cluster, including those that are almost as distant, and therefore as young, as CL J1001.
The diffuse X-ray emission detected by Chandra and ESA's XMM-Newton Observatory comes from a large amount of hot gas, one of the defining features of a true galaxy cluster.
“It appears that we have captured this galaxy cluster at a critical stage just as it has shifted from a loose collection of galaxies into a young, but fully formed galaxy cluster,” said co-author David Elbaz from CEA. Previously, only these loose collections of galaxies, known as protoclusters, had been seen at greater distances than CL J1001.
The results suggest that elliptical galaxies in galaxy clusters like CL J1001 may form their stars during shorter and more violent outbursts than elliptical galaxies that are outside clusters. Also, this discovery suggests that much of the star formation in these galaxies happens after the galaxies fall onto the cluster, not before.
In comparing their results to computer simulations of the formation of clusters performed by other scientists, the team of astronomers found that CL J1001 has an unexpectedly high amount of mass in stars compared to the cluster's total mass. This may show that the build-up of stars is more rapid in distant clusters than simulations imply, or it may show that clusters like CL J1001 are so rare that they are not found in today's largest cosmological simulations.
“We think we're going to learn a lot about the formation of clusters and the galaxies they contain by studying this object,” said co-author Alexis Finoguenov of the University of Helsinki in Finland, “and we're going to be searching hard for other examples.”
The result is based on data from a large group of observatories in space and on the ground including Chandra, NASA's Hubble Space Telescope and Spitzer Space Telescope, ESA's XMM-Newton and Herschel Space Observatory, the NSF's Karl G. Jansky Very Large Array, the Atacama Large Millimeter/submillimeter Array (ALMA) , the Institut de Radioastronomie Millimetrique Northern Extended Millimeter Array (IRAM NOEMA), and ESO's Very Large Telescope.

Don't miss this! Join Polygon's Charlie Hall as he mans an expedition to Alpha Centauri in Elite Dangerous, while space expert, Loren Grush, joins him to discuss last week's announcement that astronomers using European Southern Observatory (ESO) telescopes in Chile and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri may ultimately prove to be a habitable planet could that harbor an advanced technological civilization.
The long-sought world, designated Proxima b, orbits its cool red -dwarf parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System.
Red Dwarfs “may be one instance in which older is better,” said Seth Shostak, senior astronomer and director of California-based SETI. “Older solar systems have had more time to produce intelligent species.”

I know it's true of every modern phone, but it's especially true of Sony's new pair of Xperia handsets: the camera will be the most important factor in deciding the fortunes of the Xperia XZ and Xperia X Compact. Introduced at IFA 2016 in Berlin today, Sony's Xperia XZ triples down on camera technology with a new laser autofocus, RGBC-IR white balance sensor, and its traditionally strong 23-megapixel imaging sensor. The Japanese company's new flagship even has a dedicated shutter button. And the Xperia X Compact is a smaller, less powerful vessel for that same upgraded camera system.
One of the reasons the camera is going to be so pivotal is that the rest of the specs are not all that impressive: the Xperia XZ has the Snapdragon 820,...

In the last 30 years we've really moved into exceptional territory. Maintaining temperatures below the 1.5C guardrail requires significant and very rapid cuts in carbon dioxide emissions or co-ordinated geo-engineering. That is very unlikely. We are not even yet making emissions cuts commensurate with keeping warming below 2C.
Since the planet is our life support system -- we are essentially the crew of a largish spaceship -- interference with its functioning at this level and on this scale is highly significant. If you or I were crew on a smaller spacecraft, it would be unthinkable to interfere with the systems that provide us with air, water, fodder and climate control. But the shift into the Anthropocene tells us that we are playing with fire, a potentially reckless mode of behaviour which we are likely to come to regret unless we get a grip on the situation
Social disruption and economic consequences of such large sea level rise could be devastating. It is not difficult to imagine that conflicts arising from forced migrations and economic collapse might make the planet ungovernable, threatening the very fabric of civilization.
Climate change is real; it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.

The Pallas's cat is a small, little known wild cat species living in the steppes and mountains of Central Asia. Through a new research initiative “PICA” (Pallas's Cat International Conservation Alliance) launched earlier this year, conservationists are hoping to better understand this feline. The project is still in its early stages, but it has already produced some outstanding, rare footage of Pallas's cats, including video of wild cubs.
The footage (featured at the top of this post) was taken by a set of remote-sensor research cameras stationed in the Zoolon Mountains, in Mongolia's Gobi Gurvan Saikhan National Park. One sequence, shot during the night, shows three Pallas' cat cubs curiously examining the camera, while another snippet features an adult cat in broad daylight looking for signs of other animals.
First Footage of Pallas's Cat Cubs in This Part of Mongolia?
“This is the first footage of Pallas's cat cubs taken in this part of Mongolia as far as we know and is a valuable discovery from our project partners Snow Leopard Trust”, says David Barclay, Cat Conservation Officer at the Royal Zoological Society of Scotland (RZSS).
The cameras are part of the new international Pallas's cat conservation project, PICA, founded by the RZSS, Nordens Ark, a Swedish breeding center and zoo Nordens Ark, and U.S.-based conservation organization Snow Leopard Trust that aims to gather more information on the Pallas's cat, one of the world's least-studied felines.
“If we're hoping to conserve this mysterious cat, we need to first understand it, and we're hoping this study will bring valuable new insights.” — Emma Nygren, Nordens Ark
“We still don't know much about the Pallas's cat's behavior, or even it's true range,” says Emma Nygren, a conservation biologist at Nordens Ark who coordinates the research project. “If we're hoping to conserve this mysterious cat, we need to first understand it, and we're hoping this study will bring valuable new insights.”
The Snow Leopard Trust, which has been working in this part of Mongolia for more than a decade, is a technical and logistical partner in the project. “We're surveying these mountains for snow leopards anyway. The Pallas's cat shares the same habitat and is equally elusive, so it's a logical extension of our work to also look at them,” says Gustaf Samelius, Assistant Director of Science at the Snow Leopard Trust.
The study, which was made possible by the generous support of Fondation Segré, will continue for at least three years.
Matthias Fiechter is the Communications Manager for the Snow Leopard Trust, a Seattle, Washington-based charity with a mission to conserve the snow leopard and its mountain ecosystem through a balanced approach that considers the needs of local people and the environment.

The Department of Defense is taking action to be an environmental leader at defense facilities across the U.S.
Currently, the DOD, headed by the Defense Logistics Agency, is testing the use of biosynthetic motor oils on their non-tactical vehicle fleets. Several environmentally friendly lubricants companies have supplied bio-based motor oil to the DOD for demonstration projects across the U.S., including at Malmstrom Air Force Base in Montana. With nearly 40% of pollution in waterways coming from used motor oil, this is welcome news to help advance a new technology that need wider acceptance by large motor oil consumers.
Every year 10 billion gallons of liquid petroleum hydrocarbon, in the form of motor oil and other industrial lubricants, are released into the environment due to human activity. The majority of this coming in the form of silent oil spills, leaks from cars, and improper disposal of used oil—all contributing to the degradation of our environment and our water supply.
Almost all of the motor oils on the market today are made from refined petroleum. For years, the use of biosynthetic oils has been promoted as an environmentally friendly alternative but was long thought of as a “wouldn't that be nice” pie-in-the-sky idea that wouldn't work on a large scale in part due to the difficulty of using vegetable oils in high heat conditions like automotive engines. However, recent scientific advancements, including by the U.S. Department of Agriculture, have made this petroleum alternative dream very much a reality.
If the tests by the DOD shows that biosynthetic oils perform just as well, if not better, than the current oil being used, the switch to biosynthetic oils may be made Air Force and possibly DOD wide for use in their fleet of 200,000 vehicles in the future.
Increased availability of bio-based lubricant fluids would provide product source diversity; create additional options for government and commercial users as well as the average consumer; reduce dependence on oil imports; and decrease pollution in rivers and oceans.
Environmental as well as usability performance has become important to consumers and regulators. Today, these motor oils and lubricants made from non-toxic, environmentally friendly plant-based oils can protect us, and our environment and they are comparable to or better than petroleum oil when it comes to performance.
In the past, environmentally friendly lubricants have faced performance questions. But extensive testing has proven that biosynthetic oils not only exceed the most challenging environmental standards but also provide performance benefits not attainable with petroleum-based products alone.
This is just the beginning. Other federal agencies, such as the Department of Homeland Security's Law Enforcement Training School, are to begin testing biosynthetic oil later this year.
This large-scale change by the DOD would have widespread positive implications for our environment. While their testing will continue for the next 12-18 months there are steps that you can take to help reduce your environmental footprint. Ask your mechanic for a bio-based alternative the next time you go in for an oil change. According to the U.S. Environmental Protection Agency, just one gallon of motor oil can contaminate one million gallons of fresh water, so your small changes add up to a better environment.

My name, Amstel, is derived from the old Dutch, Aeme-stelle, which means “water area.” In the 13th Century, a small fishing village, Amstelredam, was constructed near my mouth beside a dam. Today we know that town as Amsterdam. As early as the 11th Century, farmers began building dikes to try and keep me from flooding these low lands. In 1936 my mouth was filled in and sealed shut, so that today I end at Muntplein Square, although I remain connected to a body of water called the IJ by flowing underground through pipes. The IJ (an ancient Dutch word for water) used to be a bay, but currently is considered more of a lake. During the Dutch Golden Age in the 1600's Amsterdam was the wealthiest city in the world and one of the most important ports. My extensive system of canals, built during this time, is now on the UNESCO World Heritage List.
Looking along a canal toward the Zuiderke Church, built in 1611 (and once painted by Monet).
I flow south to north through this flat and low-lying city, which is the capital of the Netherlands. Parts of me are below sea level, and some of the land around me was reclaimed from the nearby sea or marshes. Dutch children must learn to swim at an early age and receive diplomas for that effort. Some dive from houseboats and swim in my water, careful to dodge the variety of boats that are found day and night, moving upon my body.
A boy dives into the Amstel River.
All kinds of boats ply the river and canals.
I have a beer named after me! The Amstel Brewery is located along my shore, as are other breweries, and my water is sometimes used in the production of these beers. Renowned artists have painted my portrait including Rembrandt van Rijn (1606-1669), Willim Witsen (1860-1923), and Piet Mondrian (1872-1944).
With the flat terrain, the inconvenience of driving a car, and over 400 kilometers (249 miles) of bike paths in Amsterdam, humans prefer to get around by bicycle. With well over a million bikes, it is no wonder so many two-wheelers are dredged out of my stomach each year.
Amsterdam is located on approximately ninety islands and linked by over 1,400 bridges that cross back and forth. Some of these bridges are especially wonderful at night, when their lights reflect on my dark water. One in particular, the Magere Brug, uses an Old Dutch design called a ‘double swipe'. In earlier times it was opened by hand, but now an electronic mechanism raises its two sections to let boats pass underneath to enter one of the many canals that traverse Amsterdam.
Magere Brug with the full moon.
Any visitor to this city will notice a lot of plastic trash floating on my surface, and there are currently attempts to clean up my 100 kilometers (60 miles) of canals. One such venture, Plastic Whale, is a company that fishes plastic bottles and other debris from my water and transforms the trash into material to make a boat that will be used to fish for more plastic. Boat Number Seven is constructed from over seven thousand plastic bottles that might otherwise have found their way out to sea.
Someone else who recycles trash from the canals is my dear friend, the meerkoet. These waterfowl use floating debris to create their unkempt nests, which are seen everywhere wedged amongst the houseboats. The meerkoet live on my surface, and enjoy tickling my ribs when they dive down to feed on plants. The monogamous pairs also eat aquatic insects, seeds, grass, and small animals, and they are one of my favorite playmates as I flow through Amsterdam.

Rivers of lava from the volcano Kilauea leave a lava tube at a bench of new land at the Ka`ili`ili sea entry. The steam in the background is right at sea level and is caused by the boiling hot lava meeting the cool ocean water. With each wave, parts of these flows are covered by water, generating a blinding cloud of hot steam. Kilauea is the youngest and southeastern-most volcano on the big island of Hawaii. Topographically Kilauea, which is located on the southernmost flank of Mauna Loa, was thought to be an extension of its giant neighbor. However, research over the past few decades clearly shows that Kilauea has its own magma-plumbing system, extending to the surface from more than 60 kilometers deep in the Earth.

Tasmanian devils are evolving in response to a highly lethal and contagious form of cancer. A National Science Foundation-funded researcher and an international team of scientists discovered that two regions in the genomes of Australia's iconic marsupials are changing in response to the rapid spread of devil facial tumor disease (DFTD), a nearly 100 percent fatal and transmissible cancer first detected in 1996. The Washington University study suggests some Tasmanian devil populations are evolving genetic resistance to DFTD that could help the species avoid extinction. Additionally, the genomic data will support future medical research exploring how animals evolve rapidly in response to cancer and other pathogens.

Is being shy a boon or a burden? Should it be fought against? This sparkling cultural history ranges from Jane Austen to Silicon Valley
Joe Moran, like many of us, is shy. He is hopeless at small talk and feels he “should probably wear a badge that says: ‘Please do not expect sparkling conversation'”. Like most shy people, he has a dread of being boring. Thankfully Shrinking Violets, his “field guide” to shyness, exhibits all the sparkle and fluency on the page he might lack when chatting to strangers. Though he touches on his own experience, it's not a memoir, full of shaming revelations (of course it isn't): Moran says he prefers to hide “behind the human shield of people more interestingly and idiosyncratically shy than me”.
So he investigates the fifth Duke of Portland (1800-1879), who was so shy he communicated by posting notes into letter boxes inside his house, and asked the workers on his Welbeck Estate “to pass him as if he were a tree”. The duke is notable for spending a chunk of his vast fortune excavating grand, illuminated tunnels beneath his land so that when taking a walk he would never risk a meeting.
In the 80s, cardigan-wearing indie kids embraced the idea of being shy "as a personal and political philosophy"
As Hilary Mantel has said, the condition began to be regarded as "a pathology, not just an inconvenient character trait"

In the Samburu National Reserve in northern Kenya, when the fierce heat of the sun has softened into a gentle evening glow, David Daballen and I climb into a jeep to find some elephants.
As we drive through the savannah, Daballen, a conservationist at Save the Elephants, points out family groups and individuals within them. “These are the Butterflies, this group is Storms, here are the Spices,” he says. We have been looking out for Cinnamon, the Spices' matriarch, and suddenly there she is: around 50 years old, huge and tuskless, having been born without any precious ivory. Close to her is Habiba, who was orphaned along with seven siblings when poachers killed their mother in 2011. The orphans were adopted by Cinnamon and the rest of the Spices.
They are a crucial part of the ecosystem, and an iconic species. Can you imagine them no longer existing?

How are dogs and wolves similar and different? In a word? Intensity. Take any behavior exhibited by even the most uninhibited dog, then turn it up to thirty-seven and you've got that same behavior in a wolf.
Put another way, dogs dig holes; wolves dig mines. Dogs might rip up your sofa, a wolf will reduce one to feathers,splinters, springs and bits of fabric no more than a one-inch square.
I like to call wolves "raw dogs", "proto-dogs", or "the blueprint". Even with captive bred wolves, they exhibit a broader and more complex range of behavior than what I've experienced with dogs.
Even primitive dog breeds (more "wolf like" dogs) seem to be less adept at solving problems and more inclined to look towards a human for help.
Wolves have around 33% more gray matter than a comparably sized domestic dog. In general, I've witnessed the ability among wolves and high content wolfdogs to solve problems quickly that stymy dogs until they give up.
Aqutaq [my wolf], for example is incredibly adept with a lead line. She fully understands the concept of the line and that it connects us in such a way that we must be on the same side of any tall obstacle. She might be sixteen feet in front of me and on the wrong side of a tree, yet she'll anticipate this issue, and alter course such that she moves to pass the tree on the side that matches mine.
If she becomes entangled while moving through brush, she also understands to retrace the path of the line to unwind it.
Physically, they're very similar, although domestic dogs can eat foods that contain many more carbohydrates as a result of their long-term association with people. Wolves are also only reproductively active once a year, whereas dogs can cycle multiple times. Pound for pound wolves are stronger, have better endurance, have a much greater bite force, and are faster than all but a very select few breeds of dog.
For those that are curious, in my life I've had many different breeds of domestic dogs including:

The slow decline of hearing in old age is frustrating and alienating. Tyler Trumbo's short documentary, The Sound Inside, follows three elderly people who are taking a lip-reading class to mitigate the effects that hearing loss will have on their lives. The film focuses heavily on sound design and mirrors the silence and muffled noises that have become these characters' realities. “When you can't hear, you don't know what you can't hear,” says one woman. “Without the hearing aid, suddenly I feel like I've dropped in a black hole. All I hear is the noise in my head.”
