Consciousness On-Off Switch Discovered Deep In Brain

Slashdot - Sun, 07/06/2014 - 22:16
An anonymous reader writes "One moment you're conscious, the next you're not. For the first time, researchers have switched off consciousness by electrically stimulating a single brain area. Although only tested in one person, the discovery suggests that a single area – the claustrum – might be integral to combining disparate brain activity into a seamless package of thoughts, sensations and emotions. It takes us a step closer to answering a problem that has confounded scientists and philosophers for millennia – namely how our conscious awareness arises. When the team zapped the area with high frequency electrical impulses, the woman lost consciousness. She stopped reading and stared blankly into space, she didn't respond to auditory or visual commands and her breathing slowed. As soon as the stimulation stopped, she immediately regained consciousness with no memory of the event. The same thing happened every time the area was stimulated during two days of experiments.

A Tour of One of the World's Only Underwater Labs With Fabien Cousteau

Slashdot - Sun, 07/06/2014 - 21:10
An anonymous reader writes Having completed his 31-day stretch underwater, Fabien Cousteau, grandson of famed oceanographer Jacques Cousteau, shows off his underwater laboratory to PBS in this video. When asked about his observations' Fabien said' "It's just amazing, we've seen so much new behavior that I've never seen before. Fish sleeping in sponges, a goliath grouper attacking a barracuda, never seen that before, I don't think anyone has ever caught it on film before. Christmas tree worms, spawning and giving off this milky smoke like stuff off. I mean it's just science fiction, it's really amazing down here. And that's why we're down here, my grandfather used to say, in order to film a fish you must become a fish. So we're trying to get as close as we can to becoming fish."

15-Year-Old Developing a 3D Printer 10x Faster Than Anything On the Market

Slashdot - Sun, 07/06/2014 - 20:04
New submitter jigmypig writes: One of the main issues with 3D printers today is that they lack in one area; speed. A 15-year-old boy named Thomas Suarez is developing a 3D printer that he says is the most reliable, most advanced, and faster than any 3D printer on the market today. In fact he claims it is 10 times faster than any 3D printer ever created. "There's something that makes me want to keep going and keep innovating," he says, laughing at being asked if he'd be better off outside climbing trees or riding a bike. "I feel that my interests will always lie in technology. Maybe I should go outside more but I just really like this stuff."

Study: Whales Are Ecosystem "Engineers"

Slashdot - Sun, 07/06/2014 - 18:57
An anonymous reader writes Researchers had previously thought that, being excessively uncommon and migrant, whales didn't have much of an effect on the more extensive marine environment. However, a new study distributed in the journal Frontiers in Ecology and the Environment gives whales a role as "engineers" of the oceans. In the study, scientists from the University of Vermont suggest that the 13 types of extraordinary whale have an essential and positive impact on the capacity of seas, on carbon storage, and on the state of fisheries around the globe. "The decline in great whale numbers, estimated to be at least 66% and perhaps as high as 90%, has likely altered the structure and function of the oceans, but recovery is possible and in many cases is already underway," researchers wrote in an article announcing their investigation.

Newly Spotted Frozen World Orbits In a Binary Star System

Slashdot - Sun, 07/06/2014 - 17:50
An anonymous reader writes A newly discovered planet in a binary, or twin, star system located 3,000 light-years from Earth is expanding astronomers' notions of where Earth-like planets can form. At twice the mass of Earth, the planet orbits one of the stars in the binary system at almost exactly the same distance at which Earth orbits the sun. However, because the planet's host star is much dimmer than the sun, the planet is much colder than Earth. "This greatly expands the potential locations to discover habitable planets in the future," said Scott Gaudi, professor of astronomy at Ohio State. "Half the stars in the galaxy are in binary systems. We had no idea if Earth-like planets in Earth-like orbits could even form in these systems."

New Snowden Leak: of 160000 Intercepted Messages, Only 10% From Official Targets

Slashdot - Sun, 07/06/2014 - 16:45
An anonymous reader writes in with the latest news about NSA spying from documents leaked by Edward Snowden. Ordinary Internet users, American and non-American alike, far outnumber legally targeted foreigners in the communications intercepted by the National Security Agency from U.S. digital networks, according to a four-month investigation by The Washington Post. Nine of 10 account holders found in a large cache of intercepted conversations, which former NSA contractor Edward Snowden provided in full to The Post, were not the intended surveillance targets but were caught in a net the agency had cast for somebody else. Many of them were Americans. Nearly half of the surveillance files, a strikingly high proportion, contained names, e-mail addresses or other details that the NSA marked as belonging to U.S. citizens or residents. NSA analysts masked, or "minimized," more than 65,000 such references to protect Americans' privacy, but The Post found nearly 900 additional e-mail addresses, unmasked in the files, that could be strongly linked to U.S. citizens or U.S. residents."

When Beliefs and Facts Collide

Slashdot - Sun, 07/06/2014 - 15:40
schnell writes A New York Times article discusses a recent Yale study that shows that contrary to popular belief, increased scientific literacy does not correspond to increased belief in accepted scientific findings when it contradicts their religious or political views. The article notes that this is true across the political/religious spectrum and "factual and scientific evidence is often ineffective at reducing misperceptions and can even backfire on issues like weapons of mass destruction, health care reform and vaccines." So what is to be done? The article suggests that "we need to try to break the association between identity and factual beliefs on high-profile issues – for instance, by making clear that you can believe in human-induced climate change and still be a conservative Republican."

Study: Global Warming Solvable If Fossil Fuel Subsidies Given To Clean Energy

Slashdot - Sun, 07/06/2014 - 14:36
An anonymous reader writes A research team at the International Institute for Applied Systems Analysis in Laxenburg, Austria, says it has studied how much it would cost for governments to stick to their worldwide global warming goal. They've concluded that for "a 70 per cent chance of keeping below 2 degrees Celsius, the investment will have to rise to $1.2 trillion a year." Where to get that money? The researchers say that "global investment in energy is already $1 trillion a year and rising" with more than half going to fossil fuel energy. If those subsidies were spent on renewable energy instead, the researchers hypothesize that "global warming would be close to being solved."

New Single Board Computer Lets You Swap Out the CPU and Memory

Slashdot - Sun, 07/06/2014 - 08:08
ganjadude (952775) writes "I stumbled upon this little scoop and thought the Slashdot crowd would be interested in. The new kid on the block, known as the HummingBoard can handle faster processors, more RAM and will fit the same cases for the Pi. Also, you can expand the memory and the CPU is replaceable! The low end model starts at $45 and the high end costs $100. So tell me guys, what are you going to do with yours?" $45 model is a single core iMX6 (an ARMv7) with 512M of RAM, the $100 model has a dual core i.MX6 with 1G of RAM. Full specs.
