NASA and ESA To Demonstrate Earth-Moon Laser Communication 74

Posted by Unknown Lamer from the moobase-needs-youtube dept.
cylonlover writes with this news bite about a cool new ground to space laser communication system from NASA and ESA: "Space communications have relied on radio since the first Sputnik in 1957. It's a mature, reliable technology, but it's reaching its limits. The amount of data sent has increased exponentially for decades and NASA expects the trend to continue. The current communications systems are reaching their limits, so NASA and ESA are going beyond radio as a solution. As part of this effort, ESA has finished tests of part of a new communications system, in preparations for a demonstration in October in which it will receive a laser data download from a NASA lunar orbiter."

Monopoles and Magnetricity 67

Posted by Unknown Lamer from the one-pole-to-rule-them-all dept.
szotz writes "Although there was once a hint from a cosmic ray experiment (on Valentine's Day, no less), no one's found any solid evidence of monopoles (unpaired north and south magnets) flying around the cosmos. But physicists did find monopole-like quasiparticles in some exotic crystals in 2009. One of the discoverers has an article this month in IEEE Spectrum that looks at how the particles were found and what's happened since. They might seem like a wacky curiosity, but the author says we shouldn't write them off — they might one day make useful new 'magnetronic' devices."

Crowd-Funding a Mission To Jupiter's Moons 86

Posted by Soulskill from the go-big-or-go-home dept.
Daniel_Stuckey writes "Like so many great leaps for mankind, getting a human to one of Jupiter's moons must begin with a small step. And Objective Europa is aiming to do exactly that. A small team — architects, futurist designers, private space pioneers and even Jacques Cousteau's son — is beginning the planning stage to send human beings on a one-way trip to the Jovian moon Europa. The effort is headed up by Kristian Von Bengston, the founder of Copenhagen Suborbitals, an open source DIY space program based in his native Denmark. And he's quite serious about transporting a man or woman beyond our atmosphere, Mars and the asteroid belt."

Give Zebrafish Some Booze and They Stop Fearing Robots 58

Posted by Soulskill from the valuable-life-advice dept.
Zothecula writes "With some help from a robotic fish, scientists have discovered that zebrafish are much like humans in at least one way – they get reckless when they get drunk. OK, 'drunk' might not be technically accurate, but when exposed to alcohol, the fish show no fear of a robotic version of one of their natural predators, the Indian leaf fish. When they're "sober," they avoid the thing like crazy. The researchers believe that the experiments indicate a promising future for robots in behavioral studies."

$375,000 Lab-Grown Beef Burger To Debut On Monday 221

Posted by Soulskill from the order-yours-while-supplies-last dept.
sciencehabit writes "If you take some scientists' word for it, the biggest agricultural revolution since the domestication of livestock is starting on Monday — in an arts center in London. At a carefully orchestrated media event, Dutch stem cell researcher Mark Post is planning to present the world's first test-tube hamburger. Its patty — financed by an anonymous billionaire — is made from meat that Post has laboriously grown from bovine stem cells in his lab at an estimated cost of $375,000, just to prove a point: that it is possible to produce meat without slaughtering animals."

Paper: Evolution Favors Cooperation Over Selfishness 245

Posted by Soulskill from the can't-we-all-just-get-along dept.
Beeftopia writes "Conventional wisdom has suggested selfishness is most beneficial evolutionary strategy for humans, while cooperation is suboptimal. This dovetailed with a political undercurrent dating back more than a century, starting with social Darwinism. A new paper in the journal Nature Communications casts doubt on this school of thought. The paper shows that while selfishness is optimal in the short term, it fails in the long term. Cooperation is seen as the most effective long term human evolutionary strategy."

A Climate of Violence? 184

Posted by Soulskill from the venus-must-be-a-postapocalyptic-hellscape dept.
Rambo Tribble writes "U.S. researchers have come to the conclusion that a changing climate can drive increased violence in human society. Their findings are to reported in Science (abstract). 'They report a "substantial" correlation between climate and conflict. Their examples include an increase in domestic violence in India during recent droughts, and a spike in assaults, rapes and murders during heatwaves in the U.S. The report also suggests rising temperatures correlated with larger conflicts, including ethnic clashes in Europe and civil wars in Africa.' Marshall Burke, one of the authors, said, 'This is a relationship we observe across time and across all major continents around the world. The relationship we find between these climate variables and conflict outcomes are often very large.' Add this to the developing scarcity of water due to global warming and the prospects for a peaceful future do not bode well."

Google's Science Fellows Challenge the Company's Fund-Raising For Senator Inhofe 140

Posted by samzenpus from the keep-your-friends-close dept.
Lasrick writes "At the Dot Earth blog in the NY Times, 'Big companies have many, and sometimes conflicting, interests, as a spokesperson for Google tried to explain to the environmental blogger Brian Merchant this way: “[W]hile we disagree on climate change policy, we share an interest with Senator Inhofe in the employees and data center we have in Oklahoma.” Now the Web giant is facing fresh criticism, this time in an open letter from 17 scientists and policy researchers who were invited to Google’s Silicon Valley headquarters back in 2011 to explore ways to improve climate science communication....'"

Camping Helps Set Circadian Clocks Straight 173

Posted by samzenpus from the nature-time dept.
cold fjord writes "Counsel & Heal reports, 'Many people are stuck in the vicious cycle of late nights and late mornings. However, a new study reveals that a week of camping in the great outdoors may help people set their clocks straight. A new study, published in the journal Current Biology, reveals that if given a chance, our body's internal biological clocks will tightly synchronize to a natural, midsummer light-dark cycle. The study found that a week of exposure to true dawn and dusk with no artificial lights had a significant effect on people who might otherwise describe themselves as night owls. Researchers found that under those conditions, night owls quickly become early birds. "By increasing our exposure to sunlight and reducing our exposure to electrical lighting at night, we can turn our internal clock and sleep times back and likely make it easier to awaken and be alert in the morning," Kenneth Wright of the University of Colorado Boulder said in a news release.'"
