Early Plants May Have Caused Massive Glaciation 174

sciencehabit writes with this excerpt from Science: "The first plants to colonize land didn't merely supply a dash of green to a drab landscape. They dramatically accelerated the natural breakdown of exposed rocks, according to a new study, drawing so much planet-warming carbon dioxide (CO2) from the atmosphere that they sent Earth's climate spiraling into a major ice age."

Cystic Fibrosis Gene Correction Drug Approved by the FDA 264

tguyton writes "The good news: the FDA just approved the distribution of the first drug to treat the underlying cause of Cystic Fibrosis, called Kalydeco by Vertex Pharmaceuticals. The bad news: this drug will only affect 4% of patients with the disease in the U.S. From the article: '[Affected patients] with the so-called G551D mutation have a defective protein that fails to balance the flow of chloride and water across the cell wall, leading to the buildup of internal mucus. The vast majority of cystic fibrosis patients have a different genetic defect, in which the protein does not reach the cell wall. Vertex is developing another drug to try and address that problem. Study data for that drug is expected later this year.' Hopefully the research involved will be applicable to finding treatments for other genetic diseases." Further bad news: "...executives said Kalydeco would cost $294,000 for a year's supply, placing it among the most expensive prescription drugs sold in the U.S."

NASA Finds Interstellar Matter From Beyond Our Solar System 75

An anonymous reader writes "For the very first time, a NASA spacecraft has detected matter from outside our solar system — material that came from elsewhere in the galaxy. This so-called interstellar material was spotted by NASA's Interstellar Boundary Explorer (IBEX), a spacecraft that is studying the edge of the solar system from its orbit about 200,000 miles (322,000 kilometers) above Earth. 'This alien interstellar material is really the stuff that stars and planets and people are made of — it's really important to be measuring it,' said David McComas, IBEX principal investigator."

Science Panel Recommends Censoring Bird Flu Papers 126

Morty writes "The National Science Advisory Board for Biosecurity (NSABB) has recommended that details of two research papers involving Avian Flu not be published because of security concerns. At least one of the research groups says that their work should be logically reproducible. The NSABB's censorship recommendations do not (currently) have the force of law, but Science and Nature voluntarily delayed publication."

Computer Program Reconstructs Heard Words From Brain Scans 147

sciencehabit writes "In a new study, neuroscientists connected a network of electrodes to the hearing centers of 15 patients' brains and recorded the brain activity while they listened to words like 'jazz' or 'Waldo.' They saw that each word generated its own unique pattern in the brain. So they developed two different computer programs that could reconstruct the words a patient heard just by analyzing his or her brain activity. Reconstructions from the better of the two programs were good enough that the researchers could accurately decipher the mystery word 80% to 90% percent of the time. Because there's evidence that the words we hear and the words we recall or imagine trigger similar brain processes, the study suggests scientists may one day be able to tune in to the words you're thinking."

Trials and Errors: Why Science Is Failing Us 474

Lanxon writes "An in-depth feature in Wired explores the reason science may be failing us. Quoting: 'For too long, we've pretended that the old problem of causality can be cured by our shiny new knowledge. If only we devote more resources to research or dissect the system at a more fundamental level or search for ever more subtle correlations, we can discover how it all works. But a cause is not a fact, and it never will be; the things we can see will always be bracketed by what we cannot. And this is why, even when we know everything about everything, we'll still be telling stories about why it happened. It's mystery all the way down.'"

The Science of Human-Robot Love Screenshot-sm 88

MrSeb writes "Since Slashdot first covered lovotics back in July 2011, its creator — Hooman Samani — has been busy working on a couple of new applications for his fledgling scientific sphere of human-robot love: Kissenger and Mini-Surrogate. Kissenger is a robot with highly-sensitive and motor-actuated lips, which you can use to transmit a kiss to another Kissenger robot (held by a friend or loved one) over the internet. Mini-Surrogate is basically a real-world avatar that adds a physical element to video conferencing. Both are primarily for human-human use, but it's easy to imagine a Kissenger hooked up to an AI or video game. Likewise, the next Elder Scrolls game could come with a Mini-Surrogate, so that you can communicate with your in-game wife while you're knee-deep in fireballed orc."

Building the Bionic Man 129

nk497 writes "Will we soon be upgrading body parts like the components inside our PCs? 'Human enhancement' technologies are quickly evolving, making it easier to treat health conditions — and make us more powerful. Neural implants are already being used to restore vision, but in the future it could be used to give us better than 20/20 eyesight. Bionic arms will extend beyond prostheses, and be used to help boost our strength — handy for working in a warehouse and for soldiers. 'We use tools all the time to enhance our natural functions, and physical interaction is increasingly usurped by the virtual connections afforded by computers, smartphones and the internet,' said one researcher. 'So connecting these tools directly from the brain is perhaps not so far-fetched.'"

UCSD Researchers Create Artificial Cell Membrane 54

cylonlover writes with an excerpt from a Gizmag article: "The cell membrane is one of the most important components of a cell because it separates the interior from the environment and controls the movement of substances in and out of the cell. In a move that brings mankind another step closer to being able to create artificial life forms from scratch, chemists from the University of California, San Diego (UCSD), and Harvard University have created artificial self-assembling cell membranes using a novel chemical reaction. The chemists hope their creation will help shed light on the origins of life." The full paper is available in the Journal of the American Chemical Society (behind a paywall).

What If the Apollo Program Never Happened? 756

astroengine writes "In a recent debate, Republican presidential candidate Newt Gingrich said he would like to beat the Chinese back to the moon. He has even been so bold as to propose setting up a manned base by 2020, driven by empowering private industry to take the initiative. It's ironic to hear moon travel still being debated 40 years after the last Apollo landing in 1972. Between then and now, NASA's small space shuttle fleet filled in for space travel, but astronauts could only venture as far a low earth orbit — at an altitude much lower than the early pioneers reached. If there were no Apollo crash program to beat the Soviets to the moon, would we have planned to go to the moon eventually? But this time with a commitment of staying? Or would we never go?"

Ask Slashdot: Wireless Proximity Detection? 101

New submitter Cinnamon Whirl writes "As a chemist, I work in a both lab and office enviroments, and need access to data in both, without causing undue clutter in either. My company has recently purchased two Win7 tablets for trial usage with electronic lab notebooks, propietry software, SAP, email etc. These are also useful for sharing in meetings, etc. As part of this project, I have been wondering whether we can use these tablets to detect other devices by proximity. Examples could include finding the nearest printer or monitor or, perhaps trickier, could two roaming devices find each other? Although lab technology is rarely cutting edge, I can see a day when all our sensors and probes will broadcast data (wireless thermocouples are already available), and positioning information will become much more important. What technologies exist to do this? How accurate can the detection be?"

UCLA Professor Says Conventional Wisdom on Study Habits Is All Washed Up 329

An anonymous reader writes "Taking notes during class? Topic-focused study? A consistent learning environment? According to Robert Bjork, director of the UCLA Learning and Forgetting Lab, distinguished professor of psychology, and massively renowned expert on packing things in your brain in a way that keeps them from leaking out, all are three are exactly opposite the best strategies for learning."

DARPA Targets Computing's Achilles Heel: Power 100

coondoggie writes "The power required to increase computing performance, especially in embedded or sensor systems has become a serious constraint and is restricting the potential of future systems. Technologists from the Defense Advanced Research Projects Agency are looking for an ambitious answer to the problem and will next month detail a new program it expects will develop power technologies that could bolster system power output from today's 1 GFLOPS/watt to 75 GFLOPS/watt."

Lunar Base Foe Romney Endorsed By Lunar Base Supporters 318

MarkWhittington writes "Mitt Romney has infamously suggested that the idea of lunar colonies is 'zany' and has ridiculed Newt Gingrich's idea of building a lunar base by 2020. However Romney has been endorsed by a group of aerospace heavyweights, including Apollo moonwalker Gene Cernan and former NASA administrator Mike Griffin, many of whom have previously supported the idea of lunar bases."

Don't Worry About Global Warming, Say 16 Scientists in the WSJ 1367

An anonymous reader writes "According to an opinion piece in the Wall Street Journal, there's 'no compelling scientific argument for drastic action to 'decarbonize' the world's economy'. From the article: 'The lack of warming for more than a decade—indeed, the smaller-than-predicted warming over the 22 years since the U.N.'s Intergovernmental Panel on Climate Change (IPCC) began issuing projections—suggests that computer models have greatly exaggerated how much warming additional CO2 can cause. Faced with this embarrassment, those promoting alarm have shifted their drumbeat from warming to weather extremes, to enable anything unusual that happens in our chaotic climate to be ascribed to CO2. The fact is that CO2 is not a pollutant. CO2 is a colorless and odorless gas, exhaled at high concentrations by each of us, and a key component of the biosphere's life cycle.'"

Study Finds Growing Up WIth Gadgets Has a Downside: Social Skill Impairment 203

PolygamousRanchKid writes with this excerpt from a CNN story:"Tween girls who spend much of their waking hours switching frantically between YouTube, Facebook, television and text messaging are more likely to develop social problems, says a Stanford University study published in a scientific journal on Wednesday. Young girls who spend the most time multitasking between various digital devices, communicating online or watching video are the least likely to develop normal social tendencies, according to the survey of 3,461 American girls aged 8 to 12 who volunteered responses. The study only included girls who responded to a survey in Discovery Girls magazine, but results should apply to boys, too, Clifford Nass, a Stanford professor of communications who worked on the study, said in a phone interview. Boys' emotional development is more difficult to analyze because male social development varies widely and over a longer time period, he said."

Friday's Solar Flare Twice As Energetic As Monday's; Earth Safe 39

The Bad Astronomer writes "The sunspot cluster that erupted in a solar flare and coronal mass ejection last Monday burst into life again on Friday, blasting out an X2 class solar flare, twice as energetic as the last one. This one was on the Sun's limb and was pointed away from us, so we're in no danger; all we got was a very minor radiation storm that's on the lowest ranking of such things. But it did put on quite a light show, which you can see in a video created with images from NASA's Solar Dynamics Observatory."

Sea Water Could Cause Uranium Pollution From Nuclear Fuel Rods 97

New submitter Required Snark writes "UC Davis researchers have found a mechanism where the sodium in sea water can cause uranium nano-particles to be released from nuclear reactor fuel rods. Normally the uranium oxide compounds composing the rods are very resistant to leaching into water. This could have serious consequences for the Fukushima disaster, since sea water was used for emergency cooling."

Mars-Bound Probe Serves As Radiation Guinea Pig 67

sighted writes "This week's huge solar storm will benefit future astronauts, thanks to the rover Curiosity, now on its way to Mars. The rover is equipped with an instrument that measures the radiation exposure that could affect a human astronaut en route to the Red Planet. Scientists are just starting to pore over the data from the blast of particles. Don't worry about the poor robotic geologist, though: 'No harmful effects to the Mars Science Laboratory have been detected from this solar event,' says NASA."
