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.'"

TheSync writes "The long-awaited remake of Carl Sagan's amazing Cosmos series, Cosmos: A Space-Time Odyssey, will be coming to Fox television next year. 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."

A while ago you had the chance to ask mathematician and theoretical physicist Freeman Dyson about his work in quantum electrodynamics, nuclear propulsion, and his thoughts on the past, present, and future of science. Below you'll find his answers to your questions.

cylonlover writes "Invisibility cloaks have been around in various forms since 2006, when the first cloak based on optical metamaterials was demonstrated. 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."

jones_supa writes "British Psychological Society's division of clinical psychology (DCP) will on Monday issue a statement declaring that, given the lack of evidence, it is time for a 'paradigm shift' in how the issues of mental health are understood. According to their claim, there is no scientific evidence that psychiatric diagnoses such as schizophrenia and bipolar disorder are valid or useful. The statement effectively casts doubt on psychiatry's predominantly biomedical model of mental distress – the idea that people are suffering from illnesses that are treatable by doctors using drugs. The DCP said its decision to speak out 'reflects fundamental concerns about the development, personal impact and core assumptions of the (diagnosis) systems', used by psychiatry. The provocative statement by the DCP has been timed to come out shortly before the release of DSM-5, the fifth edition of the American Psychiatry Association's Diagnostic and Statistical Manual of Mental Disorders. The manual has been attacked for expanding the range of mental health issues that are classified as disorders."

astroengine writes "During an unscheduled spacewalk on the space station's exterior on Saturday morning, NASA astronauts Tom Marshburn and Chris Cassidy carried out the mother of all plumbing jobs: They detached a suspect ammonia pump, replaced it with a spare and watched for any further ammonia leakage. The emergency spacewalk was carried out in response to a troubling ammonia coolant leak that was discovered on Thursday. The coolant is used to maintain the temperature of the vast solar arrays the space station uses to generate electricity for its systems. 'It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the ammonia leak," said NASA commentator Rob Navias during the live NASA TV spacewalk broadcast. 'But so far, so "good."'"

Titus Andronicus writes "Today, NOAA reported, 'On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million for the first time since measurements began in 1958.' For comparison, over the last 800,000 years, CO2 has ranged from roughly 180 ppm to 280 ppm. 'For the entire period of human civilization, roughly 8,000 years, the carbon dioxide level was relatively stable near that upper bound. But the burning of fossil fuels has caused a 41 percent increase in the heat-trapping gas since the Industrial Revolution, a mere geological instant, and scientists say the climate is beginning to react, though they expect far larger changes in the future.' The last time Earth had 400 ppm was probably more than 3 megayears ago."

An anonymous reader writes "The Priceonomics blog has a post that looks into how so much of our scientific knowledge came to be gated by current publishing models. 'The most famous of these providers is Elsevier. It is a behemoth. Every year it publishes 250,000 articles in 2,000 journals. Its 2012 revenues reached $2.7 billion. Its profits of over $1 billion account for 45% of the Reed Elsevier Group — its parent company which is the 495th largest company in the world in terms of market capitalization. Companies like Elsevier developed in the 1960s and 1970s. They bought academic journals from the non-profits and academic societies that ran them, successfully betting that they could raise prices without losing customers. Today just three publishers, Elsevier, Springer and Wiley, account for roughly 42% of all articles published in the $19 billion plus academic publishing market for science, technology, engineering, and medical topics. University libraries account for 80% of their customers.' The article also explain how moving to open access journals would help, but says it's just one step in a more significant transformation scientific research needs to undergo. It points to the open source software community as a place from which researchers should take their cues."

astroengine writes "After the discovery of an ammonia coolant leak supplying one of the solar arrays on Thursday (video), International Space Station managers have decided to plan for an unscheduled spacewalk on Saturday to repair the problem. The final decision about whether to go ahead with the extravehicular activity will be made late on Friday. 'Good Morning, Earth! Big change in plans, spacewalk tomorrow, Chris Cassidy and Tom Marshburn are getting suits and airlock ready. Cool!', tweeted the Space Station's Expedition 35 Commander, Chris Hadfield, on hearing the news an emergency EVA may be required of his crew. 'The whole team is ticking like clockwork, readying for tomorrow. I am so proud to be Commander of this crew. Such great, capable, fun people.'"

symbolset writes "Research published yesterday in the journal Cell (abstract) by Richard Lee and Amy Wagers of Harvard has isolated GDF-11 as a negative regulator of age-associated cardiac hypertrophy. 'When the protein ... was injected into old mice, which develop thickened heart walls in a manner similar to aging humans, the hearts were reduced in size and thickness, resembling the healthy hearts of younger mice.' Through a type of transfusion called parabiotic or 'shared circulation' in mice — one old and sick, the other young and well — they managed to reverse this age-associated heart disease. From there, they isolated an active agent, GDF-11, present in the younger mouse but absent in the older, which reverses the condition when administered directly. They are also using the agent to restore other aged/diseased tissues and organs. Human applications are expected within six years. Since the basis for the treatment is ordinary sharing of blood between an older ill, and younger healthy patient, we can probably expect someone to start offering the transfusion treatment somewhere in the world, soon, to those with the means to find a young and healthy volunteer."

cylonlover writes "Millions of years have evolution has resulted in plants being the most efficient harvesters of solar energy on the planet. Much research is underway into ways to artificially mimic photosynthesis in devices like artificial leaves, but researchers at the University of Georgia are working on a different approach that gives new meaning to the term 'power plant.' Their technology harvests energy generated through photosynthesis before the plants can make use of it (abstract), allowing the energy to instead be used to run low-powered electrical devices."

Noryungi writes "Scientific American reports, in a chilling story, that the Hanford, Washington nuclear waste vitrification treatment plant is off to a bad start. Bad planning, multiple sources of radioactive waste, and leaking containment pools are just the beginning. It's never a good sign when that type of article includes the word 'spontaneous criticality,' if you follow my drift..." It seems the main problem is that the waste has settled in distinct layers, and has to be piped through corroded old tubes, leading to all sorts of exciting problems (e.g. enough plutonium aggregating to start a reaction).

DavidHumus writes "A recent study indicates that consuming vegetables from the Solanaceae family, which includes tomatoes and peppers (as well as tobacco), decreases the risk of contracting Parkinson's disease. Earlier studies had shown that smoking tobacco seems to provide protection against the disease and the newer one seems to confirm that the key ingredient is nicotine, which is present in some vegetables like peppers."
