cylonlover writes "SpaceX, the California company that is developing the reusable Dragon spacecraft, recently test-fired its new SuperDraco engine. Presently, the Dragon capsule is equipped with less-advanced Draco engines, which are designed for maneuvering the spacecraft while in orbit and during reentry. The SuperDraco, however, is intended to allow the astronauts to escape if an emergency occurs during the launch."

chill writes "A gravity-mapping spacecraft orbiting the moon has beamed home its first video of the lunar far side — a view people on Earth never see. Because the moon is tidally locked with Earth, it only presents one face to the planet's surface (the near side). The side of the moon that faces away from Earth is the far side. Only robotic spacecraft and Apollo astronauts who orbited the moon in the 1960s and 1970s have seen the far side of the moon directly."

eldavojohn writes "Agricultural biotechnology company Monsanto is now at the receiving end of a lawsuit from representatives of anyone who lived in the small town of Nitro, WV from 1949 on. This suit alleges that Monsanto spread chemical toxins all over town — most notably the carcinogenic dioxins. The plant in question produced herbicide 2,4,5-T, which was used in Vietnam as an ingredient for 'Agent Orange.' [Note: link contains some disturbing images; click cautiously.] From the article: 'Originally the suit called for Monsanto to both monitor people's health and clean up polluted property. The court rejected the property claims last year, leaving just the medical monitoring.' Strange that the suit is only allowed to address the symptom and not the root cause."

hondo77 writes with an excerpt from The Daily "'Mother Nature claimed one of her oldest living specimens (Monday) in a freak fire that destroyed a 3,500-year-old bald cypress tree towering over central Florida. Known as "The Senator," or simply "The Big Tree," the hollowed-out majestic timber, standing at 118 feet tall, ignited before dawn. Firefighters watched helplessly as the oldest tree east of the Mississippi — and the fifth oldest in the world — blazed and then collapsed in a heap of flaming embers.' The fire likely started by 'either a weeks- old lightning strike that smoldered until combustion occured, or friction caused by buffeting winds that ignited a spark and erupted in flames.'"

A type of invasive African grass is a major cause of wildfires in Australia. The giant gamba grass is too large for cattle and the native marsupial grazers to eat, but David Bowman, a professor of environmental change biology at the University of Tasmania has a plan. He says that elephants or rhinoceroses could eat the pest grass. "... the only other methods likely to control gamba grass involve using chemicals or physically clearing the land, which would destroy the habitat. Using mega-herbivores may ultimately be more practical and cost-effective, and it would help to conserve animals that are threatened by poaching in their native environments," he said. This plan makes you wonder just how big a Chinese needle snake can grow.

First time accepted submitter techgeek0279 writes "Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into one-, two- and even three-dimensional macroscopic structures."

sciencehabit writes "A new analysis reveals the intricacies of spider web design, showing how the unique properties of its silk turn webs into flexible yet strong traps. Computer simulations reveal that heavy forces spread over the entire net rather than stay local. Real spider silk can be either stretchy or stiff at different times, which produces threads that flex and then snap in just the right way to avoid wrecking nearby spokes."

ananyo writes "In its battle against a sluggish economy, Japan's government is gearing up to make cost savings through a root-and-branch reform of the country's science system, merging some of its most prominent research organizations. Plans approved by the government's cabinet would consolidate the RIKEN network of basic-research laboratories with the National Institute for Materials Science (NIMS), the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the National Research Institute for Earth Science and Disaster Prevention (NIED) and the Japan Science and Technology Agency (JST) — the national funding body. But with few details about the timing, potential cost savings or full implications of the change, many researchers are concerned that it could be a recipe for harsh funding cuts and even greater bureaucracy."

redletterdave writes "Singaporean researchers have created a miniature robot with a pincer and a hook that can remove early-stage stomach cancers without leaving any scars. Mounted on an endoscope, it enters the patient's gut through the mouth. It has a pincer to hold cancerous tissues, and a hook that slices them off and coagulates blood to stop bleeding. With the help of a tiny camera attached to the endoscope, the surgeon sees what's inside the gut and controls the robotic arms remotely while sitting in front of a monitor screen. The robot has already helped remove early-stage stomach cancers in five patients in Hong Kong and India, using a fraction of the time normally taken in open and keyhole surgeries that put patients at higher risk of infection and leave behind scars."

Zothecula writes "Last year, NASA announced it was seeking proposals for mission concept studies of a high-power solar electric propulsion (SEP) system that could be used in a 'space tugboat.' Such a ship would be used to ferry payloads in low Earth orbit (LEO) into higher energy orbits, including geosynchronous Earth orbit (GEO) and Lagrange point one (L1) — saving on fuel and the use of expensive secondary boosters. NASA also anticipates an SEP system could be used to propel spacecraft into deep space for science missions and for the placement, service, resupply, repositioning and salvaging of space assets by commercial operators."

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."

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."

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."

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."

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."

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.'"

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."

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.'"

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).

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?"
