Super-Earth Discovered In Star's Habitable Zone 135

Posted by samzenpus
from the big-house dept.
astroengine writes "The family of planets circling a relatively close dwarf star has grown to six, including a potential rocky world at least seven times more massive than Earth that is properly located for liquid water to exist on its surface, a condition believed to be necessary for life. Scientists added three new planets to three discovered in 2008 orbiting an orange star called HD 40307, which is roughly three-quarters as massive as the sun and located about 42 light-years away in the constellation Pictor. Of particular interest is the outermost planet, which is believed to fly around its parent star over 320 days, a distance that places it within HD 40307's so-called "habitable zone.""

Elon Musk Will Usher In the Era of Electric Cars 336

Posted by Soulskill
from the fine-but-can-we-at-least-do-it-on-mars dept.
pigrabbitbear writes "There's a reason why Elon Musk is being called the next Steve Jobs. Like Jobs, he's a visionary, a super successful serial entrepreneur, having made his initial fortune with a company he sold to Compaq before starting Paypal. Like Jobs, he saved his beloved baby Tesla Motors from the brink of oblivion. Like Jobs, [he has] a knack for paradigm-shifting industry disruption. Which means he's also demanding. 'Like Jobs, Elon does not tolerate C or D players,' SpaceX board member and early Tesla investor Steve Jurvetson told BusinessWeek. But while Jobs was slinging multi-colored music players and touchable smartphones, Musk is building rocket ships and electric-powered supercars. It's why his friends describe him as not just Steve Jobs but also John D. Rockefeller and Howard Hughes all wrapped in one. His friend Jon Favreau used Musk as the real-life inspiration for the big screen version of Tony Stark. Elon Musk is a badass."

Study: the Universe Has Almost Stopped Making New Stars 228

Posted by Soulskill
from the getting-lazy dept.
SternisheFan sends this quote from Wired: "An international team of astronomers used three telescopes — the UK Infrared Telescope and the Subaru Telescope, both in Hawaii, and Chile's Very Large Telescope — to study trends in star formation, from the earliest days of the universe. Extrapolating their findings has revealed that half of all the stars that have ever existed were created between 9 and 11 billion years ago, with the other half created in the years since. That means the rate at which new stars are born has dropped off massively, to the extent that (if this trend continues) 95 percent of all the stars that this universe will ever see have already been born. Several studies have looked at specific time 'epochs', but the different methods used by each study has restricted the ability to compare their findings and discern a fuller model of how stars have evolved over the course of the entire universe's lifespan."

Man Charged £2,000 For Medical Records Stored On Obsolete System 368

Posted by Soulskill
from the boy-that-costs-a-ton dept.
An anonymous reader writes "In Britain, where it is custom and practice to charge around £10 for a copy of your medical results, a patient has discovered that his copy will cost him £2,000 because the records are stored on an obsolete system that the current IT systems cannot access. Can this be good for patient care if no-one can access records dating back from a previous filing system? Perhaps we need to require all current systems to store data in a way that is vendor independent, and DRM-free, too?"

MIT Slows Down Speed of Light In New Game 113

Posted by Unknown Lamer
from the woah-man dept.
New submitter schirra writes "Researchers at MIT Game Lab have created a free video game that accurately simulates the effects of Einstein's relativity. 'A Slower Speed of Light' challenges players to collect objects strewn throughout a level to artificially lower the speed of light. As light speed slows to walking pace, it makes visible the unusual effects one encounters when traveling close to the speed of light, such as the Doppler effect, searchlight effect and Lorentz transformation. The effects are, in a word, trippy. The team plans to release an open-source Unity3D toolkit called OpenRelativity to allow others to include the same relativistic effects in other games." They also plan to release the source code sometime next year (despite reports that it is open source already).

from the good-work-folks dept.
An anonymous reader sends this excerpt from Western University in Canada: "The first human applied clinical study (SAV CT 01) using a genetically modified killed whole-virus vaccine (SAV001-H) to evaluate its safety and tolerability was initiated in March 2012. This study is a randomized, observer-blinded, placebo-controlled study of killed whole HIV-1 vaccine (SAV001-H) following intramuscular (IM) administration. Infected men and women, 18-50 years of age, have been enrolled in this study and randomized into two treatment groups to administer killed whole HIV-1 vaccine (SAV001-H) or placebo. Sumagen announced today the patient enrollment has progressed smoothly and there have been no adverse effects observed including local reactions, signs/symptoms and laboratory toxicities after SAV001-H injection in all enrolled patients to date. With these interim results, the SAV001-H has proven safety and tolerability in humans and given Sumagen confidence for the next clinical trials to prove its immunogenicity and efficacy evaluation."

A Piezoelectric Pacemaker That Is Powered By Your Heartbeat 84

Posted by samzenpus
from the no-batteries-required dept.
MrSeb writes "Engineers at the University of Michigan have created a pacemaker that is powered by the beating of your heart — no batteries required. The technology behind this new infinite-duration pacemaker is piezoelectricity. Piezoelectricity is is literally 'pressure electricity,' and it relates to certain materials that generate tiny amounts of electricity when deformed by an external force — which, in the case of the perpetual pacemaker, the vibrations in your chest as your heart pumps blood around your body. Piezoelectric devices generate very small amounts of power — on the order of tens of milliwatts — but it turns out that pacemakers require very little power. In testing, the researchers' energy harvester generated 10 times the required the power to keep a pacemaker firing. Currently, pacemakers are battery powered — and the battery generally need to be replaced every few years, which requires surgery. According M. Amin Karami, the lead researcher, 'Many of the patients are children who live with pacemakers for many years,' he said. 'You can imagine how many operations they are spared if this new technology is implemented.' This piezoelectric energy harvester is about half the size of a conventional battery, too, which is presumably a good thing."

Singapore Builds First Vertical Vegetable Farm 141

kkleiner writes "Short on arable land? One solution would be to plan up. Singapore, a small country that imports most of its food, has now begun selling vegetables from its first vertical farm. And even while they're more expensive the vegetables are already selling faster than they can be grown. If the farms prove sustainable – both technologically and economically – they could provide a much desired supplement to Singapore's locally grown food and serve as a model for farming in other land-challenged areas."

Killer Asteroids Are Good For Life 70

Posted by samzenpus
from the life-from-above dept.
Hugh Pickens writes "NASA reports that according to a study by Rebecca Martin and Mario Livio asteroid collisions may have provided a boost to the birth and evolution of complex life on earth delivering water and organic compounds to the early Earth and accelerating the rate of biological evolution with occasional impacts to disrupt a planet's environment to the point where species must try new adaptation strategies. 'Too many asteroids, and you've got an unrelenting cosmic shooting gallery, raining fiery death from above,' writes Fraser Cain. 'Too few asteroids, and complex life might not get the raw material it needs to get rolling. Life never gets that opportunity to really shake things up and evolve into more complex forms.' Martin and Livio suggest that the location of an asteroid belt relative to a Jupiter-like planet is not an accident. The asteroid belt in our solar system, located between Mars and Jupiter, is a region of millions of space rocks that sits near the 'snow line,' which marks the border of a cold region where volatile material such as water ice are far enough from the sun to remain intact. 'To have such ideal conditions you need a giant planet like Jupiter that is just outside the asteroid belt [and] that migrated a little bit, but not through the belt,' Livio explains. 'If a large planet like Jupiter migrates through the belt, it would scatter the material. If, on the other hand, a large planet did not migrate at all, that, too, is not good because the asteroid belt would be too massive. There would be so much bombardment from asteroids that life may never evolve.'"

JPL Employee's Firing Wasn't Due To Intelligent Design Advocacy, Says Judge 477

Posted by Soulskill
from the does-not-play-well-with-others dept.
SternisheFan writes with an update to a story from earlier this year about a lawsuit in which David Coppedge alleged he was fired from NASA's Jet Propulsion Laboratory for his advocacy of Intelligent Design. Now, a judge has ruled that Coppedge was legitimately dismissed for performance reasons. From the article: "n 2009, he apparently got a bit aggressive about promoting these ideas at work, leading one employee to complain. The resulting investigation found that he had also aggressively promoted his opinion on California's gay marriage ban, and had attempted to get JPL's holiday party renamed to 'Christmas party.' ... Coppedge was warned about his behavior at work, but he felt it was an infringement of his religious freedom, so he sued. Shortly after, as part of a set of cutbacks on the Cassini staff, he was fired. In court, Coppedge and his lawyer portrayed him as being targeted for promoting an idea that is, to put it mildly, not popular with scientists. But JPL's legal team introduced evidence that his aggressive promotion of it at work was part of a pattern of bad interactions with his fellow employees that dated back at least five years earlier."

A Parks Canada inspection party set out to investigate and stepped ashore to find that the island's three main hot spring pools, which once bubbled with water as warm as 77 Celsius, were bone dry. "Not even a small puddle," said Mr. Gladstone. Surrounding rocks, once warm to the touch, were cold." The earthquake measured 7.7 on the Richter scale."

Thousands of Lab Mice Lost In Sandy Flooding 88

Posted by Soulskill
from the george-bush-doesn't-care-about-mouse-people dept.
An anonymous reader writes "While New York University's Langone Medical Center in lower Manhattan was the site of heroism as 260 patients were evacuated from flooded floors and a nearly complete loss of power, similar floods at NYU's nearby Smilow Research Building killed thousands of laboratory mice, including genetically altered specimens in-bred over many generations as research subjects for melanoma and other diseases. Other laboratory animals, cells, and living tissue used in medical research were also lost; because of the gestation period involved, some projects were likely set back a number of years. Past experience with storms such as Allison in Houston and Katrina in New Orleans has shown that keeping laboratory animals in basements is not good practice, but research institutions keep doing it anyway."

Massachusetts May Soon Change How the Nation Dies 439

Posted by Soulskill
from the i-bet-it-involves-the-red-sox dept.
Hugh Pickens writes "Lewis M. Cohen reports that this Election Day, Massachusetts is poised to approve the Death With Dignity Act, a modernized, sanitized, politically palatable term that replaces the now-antiquated expression 'physician-assisted suicide.' Oregon's Death With Dignity Act has been in effect for the past 14 years, and the state of Washington followed suit with a similar law in 2008. But the Massachusetts ballot question has the potential to turn death with dignity from a legislative experiment into the new national norm, because the state is the home of America's leading medical publication (the New England Journal of Medicine), hospital (Massachusetts General), and four medical schools (Harvard, Boston University, University of Massachusetts, and Tufts). If the act passes in Massachusetts, other states that have previously had unsuccessful campaigns will certainly be emboldened to revisit this subject. The initiative would allow terminally ill patients with six months or less to live to request from their doctor a prescription for a lethal dose of a drug. Doctors do not have to offer the option at all, and patients must make three requests, two verbal and one written. They must self-administer the drug, which would be ingested. The patients must be deemed capable of making an informed decision. 'It's all about choice,' says George Eighmey, a key player in instituting the Oregon law, defending it against repeal and shepherding it into reality. 'You decide. No one else can decide for you. No can can force you into it, coerce you into it or even suggest it to you unless you make a statement: "I don't want to live like this any more" or "I'm interested in that law out there, doctor, can you give me something to alleviate this pain and suffering."'"

Crushed Silicon Triples Life of Li-Ion Batteries In the Lab 123

Posted by Soulskill
from the get-me-a-hammer dept.
derekmead writes "Batteries rule everything around us, which makes breakthroughs a big deal. A research team at Rice says they have produced a nice jump: by using a crushed silicon anode in a lithium-ion battery, they claim to have nearly tripled the energy density of current li-ion designs. Engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature's Scientific Reports (it has yet to be published online) that by taking porous silicon and crushing it, they were able to dramatically decrease the volume required for anode material. Silicon has long been looked at as an anode material because it holds up to ten times more lithium ions than graphite, which is most commonly used commercially. But it's previously been difficult to create a silicon anode with enough surface area to cycle reliably. Silicon also expands when it's lithiated, making it harder to produce a dense anode material. After previously testing a porous silicon 'sponge,' the duo decided to try crushing the sponges to make them more compact. The result is a new battery design that holds a charge of 1,000 milliamp hours per gram through 600 tested charge cycles of two hours charging, two hours discharging. According to the team, current graphite anodes can only handle 350 mAh/g."
