ananyo writes "Global warming is changing the location of Earth's geographic poles, according to a study published this week. Researchers at the University of Texas, Austin, report that increased melting of the Greenland ice sheet — and to a lesser degree, ice loss in other parts of the globe — helped to shift the North Pole several centimeters east each year since 2005. From 1982 to 2005, the pole drifted southeast towards northern Labrador, Canada, at a rate of about 2 milliarcseconds — or roughly 6 centimetres — per year. But in 2005, the pole changed course and began galloping east towards Greenland at a rate of more than 7 milliarcseconds per year (abstract). The results suggest that tracking polar shifts can serve as a check on current estimates of ice loss. Scientists can locate the north and south poles to within 0.03 milliarcseconds by using Global Positioning System measurements to determine the angle of Earth's spin. When mass is lost in one part of a spinning sphere, its spin axis will tilt directly towards the position of the loss — exactly as the team observed for Greenland."

Now, Page has come forward and revealed that he suffers from partial paralysis of each of his vocal chords, an 'extremely rare' condition. Not unlike what Sergey Brin and his wife are doing with Parkinson's research, Page and his wife will be funding and overseeing 'a significant research program' led by Dr. Steven Zeitels of Harvard Medical School."
cylonlover writes "Due to their relative faintness compared to their parent stars, most known exoplanets have been discovered using indirect detection methods – that is, detecting the effects they have rather than observing them directly. There are numerous indirect methods that have proven useful in the detection of exoplanets and now yet another, which relies on Einstein's special theory of relativity (abstract), has joined the list with the discovery of an exoplanet known as Kepler-76b."
ananyo writes "Researchers hoping to get '2' as the answer for a long-sought proof involving pairs of prime numbers are celebrating the fact that a mathematician has wrestled the value down from infinity to 70 million. That goal is the proof to a conjecture concerning prime numbers. Primes abound among smaller numbers, but they become less and less frequent as one goes towards larger numbers. But exceptions exist: the 'twin primes,' which are pairs of prime numbers that differ in value by 2. The twin prime conjecture says that there is an infinite number of such twin pairs. Some attribute the conjecture to the Greek mathematician Euclid of Alexandria, which would make it one of the oldest open problems in mathematics. The new result, from Yitang Zhang of the University of New Hampshire in Durham, finds that there are infinitely many pairs of primes that are less than 70 million units apart. He presented his research on 13 May to an audience of a few dozen at Harvard University in Cambridge, Massachusetts. Although 70 million seems like a very large number, the existence of any finite bound, no matter how large, means that that the gaps between consecutive numbers don't keep growing forever."
kkleiner writes "The first NeuroGaming Conference and Expo took place at the beginning of May to showcase the convergent technologies that are paving the way toward gaming with your mind. Tech news has been dominated with stories about Google Glass and the Oculus Rift, which was on display for attendees to test out. Other technologies that utilize EEG are opening up possibilities of a controller-free gaming experience into virtual realities with unlimited potential. 'Deeper questions surrounding the morality of neurogames will be sure to stir debate. As virtual reality technology inches closer to lifelike resolution, should gamers simulate themselves as characters engaged in acts of violence or criminal activity? It’s unpredictable what these games could uncover about the user as neurogames gain insight into a users’ psyche and how they respond to stimuli at a subconscious level. For instance, a game could uncover how its user particularly enjoys shooting at civilians in gameplay. Games might even become expert at diagnosing psychiatric disorders. As computers become exponentially more powerful, game resolution could fully mimic our ever-present reality.'"

It will star astrophysicist Neil deGrasse Tyson. Surprisingly, Seth MacFarlane of Family Guy fame is an executive producer. MacFarlane was introduced to Carl Sagan's widow Ann Druyan by deGrasse Tyson, and MacFarlane helped them pitch the show to Fox executives."
An anonymous reader writes "If an imposing 2300-year old Mayan temple situated at the Nohmul complex in northern Belize was on your list of things to see before you die, you're too late. The monument was essentially destroyed by a construction crew in order to provide gravel for road construction. Archaeologists expressed shock, as Nohmul (the "great mound") was a major Mayan religious center in its day. While the pyramid was situated on private property, such historical sites are supposedly protected by ordinance, and officials may file criminal charges."
ananyo writes "Volcanologists detonated explosive charges buried in a meadow in Ashford, New York, blowing 12 small craters in the ground and throwing debris 80 meters in the air. The aim was to recreate, in true-to-life detail, what happens when a volcanic eruption punches through Earth's crust. The work could guide the way that active volcanoes are monitored, and could help safety officials to decide where to restrict public access at volcanoes such as Italy's Stromboli, where dozens of tourists arrive every night to watch spectacular fire fountain displays."
sciencehabit writes "The carnivorous humped bladderwort, found on all continents except Antarctica, is a model of ruthless genetic efficiency. Only 3% of this aquatic plant's DNA is not part of a known gene, new research shows. In contrast, only 2% of human DNA is part of a gene. The bladderwort, named for its water-filled bladders that suck in unsuspecting prey, is a relative of the tomato. The finding overturns the notion that this repetitive, non-coding DNA, popularly called 'junk' DNA, is necessary for life."

The design of cloaking devices has come a long way in the past seven years, as illustrated by a simple, yet highly effective, radar cloak developed by Duke University Professor Yaroslav Urzhumov, that can be made using a hobby-level 3D printer."
PolygamousRanchKid writes in with news about a U.N. plan to get more bugs in your belly. "The U.N. has new weapons to fight hunger, boost nutrition and reduce pollution, and they might be crawling or flying near you right now: edible insects. The Food and Agriculture Organization on Monday hailed the likes of grasshoppers, ants and other members of the insect world as an underutilized food for people, livestock and pets. Insects are 'extremely efficient' in converting feed into edible meat, the agency said. Most insects are likely to produce fewer environmentally harmful greenhouse gases, and also feed on human and food waste, compost and animal slurry, with the products being used for agricultural feed, the agency said. 'Insects are everywhere and they reproduce quickly,' the agency said, adding they leave a 'low environmental footprint.' The agency noted that its Edible Insect Program is also examining the potential of arachnids, such as spiders and scorpions."

An anonymous reader writes "Worldwide levels of the chief greenhouse gas that causes global warming have hit a milestone, reaching an amount never before encountered by humans, federal scientists said. Carbon dioxide was measured at 400 parts per million at the oldest monitoring station in Hawaii, which sets the global benchmark. More than half of plants and a third of animal species are likely to see their living space halved by 2080 if current trends continue."
Dr. Mark Post hopes to bring the dream of cultured meat one step closer to reality when he unveils his high tech hamburger in London. The five ounce burger is composed of 20,000 strips of beef muscle tissue grown in a laboratory at a cost of $325,000 (provided by an anonymous donor.) From the article: "The hamburger, assembled from tiny bits of beef muscle tissue grown in a laboratory and to be cooked and eaten at an event in London, perhaps in a few weeks, is meant to show the world — including potential sources of research funds — that so-called in-Vitro meat, or cultured meat, is a reality."
