Antibody Cocktail Cures Monkeys of Ebola 101

ananyo writes "Monkeys infected with Ebola have been cured by a cocktail of three antibodies first administered 24 hours or more after exposure. The result raises hopes that a future treatment could improve the chances of humans surviving the disease caused by the deadly virus, which kills up to 90% of infected people and could potentially be used as a biological weapon. Most treatment regimes tested to date only improve chances of survival if administered within one hour of infection (abstract)."

Video Elon Musk Shows off the Dragon Capsule, Back From Space (Video) Screenshot-sm 106

Elon Musk appeared Wednesday at SpaceX's testing facility in McGregor, Texas — not far from Waco — along with NASA administrator Charles Bolden, to show off the recovered Dragon capsule that recently launched from Cape Canaveral to the ISS. He says the SpaceX Grasshopper reusable lift vehicle will start testing in a few months, and that once it's in service the cost of a flight to orbit may cost as little as 1/100 as much as it costs today. According to Musk, fuel is only a tiny part of what a space launch costs; boosters and other expensive items that currently only get used once are the main budget-busters. (Note that the Scaled Composites Space Ship Two also relies on a reusable first stage — and that theirs saves both fuel and wear & tear by using aerodynamic lift, AKA wings, for the first 50,000 feet.)

Bonobos Join Chimps As Closest Human Relatives 259

sciencehabit writes "Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do. The team also found some small but tantalizing differences in the genomes of the three species—differences that may explain how bonobos and chimpanzees don't look or act like us even though we share about 99% of our DNA."

Bank Robbing a Terrible Business, Statistically 207

isoloisti writes "Three UK economists got access to national data on bank robberies. The conclusion is that robbing banks pays, but not very much. Average take is about $19k per person per robbery. But, there's a 20% chance of being caught per raid. To make an average income, a robber needs to do two jobs per year, and has greater than 50% chance to be in the slammer after 2 years."

ESA Announces the Summer of Code In Space 2012 23

New submitter juli1 writes "The European Space Agency announced the second edition of the Summer Of Code In Space (SOCIS2012), a similar initiative to the Google Summer of Code but more related to space software. The goal is to support students in contributing to open source projects that are connected to the space domain. Students' contribution is reviewed by selected mentoring organizations and likely reversed to the main branch of each project. According to the time-line, mentoring organizations can apply now and accepted students would start their projects beginning of August and write code until October. Upon successful completion of the program, students will receive 4000 euros."

Tropical Lakes On Saturn Moon Could Expand Options For Life 84

ananyo writes "Nestling among the dunes in the dry equatorial region of Saturn's moon Titan is what appears to be a hydrocarbon lake. The observation, by NASA's Cassini spacecraft, suggests that oases of liquid methane — which might be a crucible for life — lie beneath the moon's surface. Besides Earth, Titan is the only object in the Solar System to circulate liquids in a cycle of rain and evaporation, although on Titan the process is driven by methane rather than water. This cycle is expected to form liquid bodies near the moon's poles, but not at its dune-covered equator. Now scientists think they have found a tropical lake — some 60 kilometers long and 40 kilometers wide, and at least 1 meter deep — in Cassini observations made between 2004 and 2008. Because tropical lakes on Titan should evaporate over a period of just a few thousand years, the researchers argue that these ponds and lakes are being replenished by subsurface oases of liquid methane. That would expand the number of places on the moon where life could potentially originate."

MIT Creates Glucose Fuel Cell To Power Implanted Brain-Computer Interfaces 95

MrSeb writes "Neuroengineers at MIT have created an implantable fuel cell that generates electricity from the glucose present in the cerebrospinal fluid that flows around your brain and spinal cord. The glucose-powered fuel cell is crafted out of silicon and platinum, using standard semiconductor fabrication processes. The platinum acts as a catalyst, stripping electrons from glucose molecules, similar to how aerobic animal cells (such as our own) strip electrons from glucose with enzymes and oxygen. The glucose fuel cell produces hundreds of microwatts (i.e. tenths of a milliwatt), which is a surprisingly large amount — it comparable to the solar cell on a calculator, for example. This should be more than enough power to drive complex computers — or perhaps more interestingly, trigger clusters of neurons in the brain. In theory, this glucose fuel cell will actually deprive your brain of some energy, though in practice you probably won't notice (or you might find yourself growing hungry sooner)."

Ask Slashdot: Why Are Hearing Aids So Expensive? 629

solune writes "You can get a tablet these days for a few hundred dollars, and laptops for a few hundred more. Gaming consoles, TVs, and smartphones are all available for under a thousand bucks. Yet, a decent hearing aid for my mom will go upwards of $3000! With ever-shrinking electronic components, better capabilities, and technological advancements, not to mention the rapidly increasing potential user base, I would think quality hearing aids should be coming in a lot cheaper than what we can find. Adding fuel to my fire is that a hearing aid will greatly improve my mom's life — not to mention the lives of millions of others out there. Currently, she suffers from frustration and isolation with having to ask people to 'speak up', and nodding her head to things her kids and grandkids say. We've tried the cheapies, and they're fraught with problems. So, can someone tell me why a hearing aid should be so expensive?"

Why Groundwater Use May Not Explain Half of Sea-Level Rise 244

New submitter Sir Realist writes "A recent Slashdot scoop pointed us at a scientific study that claimed 42% of global sea-level rises could be due to groundwater use. It was a good story. But as is often the way with science, there are folks who interpret the data differently. Scott Johnson at Ars Technica has a good writeup which includes two recent studies that came to remarkably different conclusions from mostly the same data, and an explanation of the assumptions the authors were making that led to those differences. Essentially, there is some reason to think that the groundwater estimates used in the first study were too high. However, that's still under debate, so it's worth reading the whole argument. Scientific review in action!"

Drug Company Disguised Advertising As Science 172

ananyo writes "A former pharmaceutical company employee has blown the whistle on drug promotion disguised as science. Drug companies occasionally conduct post-marketing studies to collect data on the safety and efficacy of drugs in the real world, after they've been approved by the U.S. Food and Drug Administration. 'However,' writes the anonymous author in an editorial in the British Medical Journal (subscription required), 'some of the [post-marketing] studies I worked on were not designed to determine the overall risk:benefit balance of the drug in the general population. They were designed to support and disseminate a marketing message.' According to the whistleblower, the results of these studies were often dubious. 'We occasionally resorted to "playing" with the data that had originally failed to show the expected result,' he says. 'This was done by altering the statistical method until any statistical significance was found.' He adds that the company sometimes omitted negative results and played down harmful side effects. Nature says it was unable to work out who the writer was but they likely worked on diabetes and the studies criticized were from the Denmark-based pharmaceutical company Novo Nordisk."

Journal Offers Flat Fee For 'All You Can Publish' 53

ananyo writes "In what publishing experts say is a radical experiment, a new open-access venture is asking its authors for only a one-off fee to secure a lifetime membership that will allow them to publish free, peer-reviewed research papers. The venture, called PeerJ, formally announced its launch on 12 June. The model represents a big departure for science publishing, which has traditionally been dominated by two basic business models: either subscribers pay for access, or authors pay for each publication — often thousands of dollars — with access being free."

Why Smart People Are Stupid 337

nicholast writes "There's a good piece by Jonah Lehrer at the New Yorker about why smart people are often more likely to make cognitive errors than stupid people. The article examines research about the shortcuts that our brains take while answering questions, and explains why even the smartest people take these shortcuts too. Quoting: 'One provocative hypothesis is that the bias blind spot arises because of a mismatch between how we evaluate others and how we evaluate ourselves. When considering the irrational choices of a stranger, for instance, we are forced to rely on behavioral information; we see their biases from the outside, which allows us to glimpse their systematic thinking errors. However, when assessing our own bad choices, we tend to engage in elaborate introspection. We scrutinize our motivations and search for relevant reasons; we lament our mistakes to therapists and ruminate on the beliefs that led us astray. The problem with this introspective approach is that the driving forces behind biases—the root causes of our irrationality—are largely unconscious, which means they remain invisible to self-analysis and impermeable to intelligence. In fact, introspection can actually compound the error, blinding us to those primal processes responsible for many of our everyday failings.'"

NASA Rover May Contaminate Its Samples of Mars 147

sciencehabit writes "The Curiosity rover will definitely find evidence of an advanced civilization if it lands safely on Mars. That's because rock samples the rover drills are likely to be contaminated with bits of Teflon from the rover's machinery, NASA announced during a press teleconference. The bits of Teflon can then mix with the sample, which will be vaporized for analysis. The problem for the scientists is that Teflon is two-thirds carbon — the same element they are looking for on Mars." Fortunately, this problem isn't a showstopper: "...there are still mitigation steps to take if SAM's analysis is potentially compromised. Contaminant production appears to be stronger in the drill's percussion mode, when it pounds powerfully and rapidly on Martian rock. So ratcheting the percussion down, or switching over to the more gentle rotary mode, may make the issue more manageable. If that doesn't work, the MSL team could just take the drill out of commission, solely scooping soil instead of also boring into rock. Curiosity could still access the interior of some Martian rocks by rolling over them with its wheels, Grotzinger said. But all in all, he's confident that the team will figure things out in the next month or two."

Hungarian Sequencing Company Vets DNA For 'Gypsy Or Jew' Genes 467

ananyo writes "Hungary's Medical Research Council (ETT), which advises the government on health policy, has asked public prosecutors to investigate a genetic-diagnostic company that certified that a member of parliament did not have Roma or Jewish heritage. The MP in question is a member of the far-right Jobbik party, which won 17% of the votes in the general election of April 2010. He apparently requested the certificate from the firm Nagy Gén Diagnostic and Research. The company produced the document in September 2010, a few weeks before local elections. Nagy Gén scanned 18 positions in the MP's genome for variants that it says are characteristic of Roma and Jewish ethnic groups; its report concludes that Roma and Jewish ancestry can be ruled out." Adds ananyo: "The test is of-course nonsense, and notions of 'racial purity' have long been discredited." Just when you think the world is too modern for such things, modernity gets hijacked by flim-flam.

DNA Modifications Change As We Age 62

sciencehabit writes "As we age, the core of our biological being — the sequence of our DNA, which makes up our genes — remains the same. Yet recent research suggests that more subtle chemical changes to our DNA occur as we age. Now, a comparison of the DNA of a newborn baby with that of a centenarian shows that the scope of these changes can be dramatic, and they may help explain why our risk of cancer and other diseases increases as we get older."

New Curiosity Rover Landing Target May Save Months Travel to Prime Destination 64

coondoggie writes with an update on the Mars Science Laboratory. From the article: "Even as it hurtles towards an August 5 rendezvous with the red planet, NASA's Mars Science Laboratory (MSL) is being fine-tuned for a more precise landing and better operations once it reaches its destination. NASA today gave a status report for the MSL which was launched November 2011, and is still over 17.5 million kilometers away from Mars. Of major interest today was the fact NASA said it has narrowed landing target for the Mars rover, Curiosity letting it touch down closer to its ultimate destination for science operations, but also closer to the foot of a mountain slope that poses a landing hazard, the agency said." From NASA: "The larger ellipse, 12.4 miles (20 kilometers) by 15.5 miles (25 kilometers) was already smaller than the landing target area for any previous Mars mission, due to this mission's techniques for improved landing precision. Continuing analysis after the Nov. 26, 2011, launch resulted in confidence in landing within an even smaller area [handy diagram], about 12 miles by 4 miles (20 by 7 kilometers). Using the smaller ellipse, the Mars Science Laboratory Project also moved the center of the target closer to the mountain, which holds geological layers that are the prime destination for the rover. ... 'We're trimming the distance we'll have to drive after landing by almost half,' said Pete Theisinger, Mars Science Laboratory project manager ... 'That could get us to the mountain months earlier.'"

Invasive Species Ride Tsunami Debris To US Shore 173

An anonymous reader writes "When a floating dock the size of a boxcar washed up on a sandy beach in Oregon, beachcombers got excited because it was the largest piece of debris from last year's tsunami in Japan to show up on the West Coast. But scientists worried it represented a whole new way for invasive species of seaweed, crabs and other marine organisms to break the earth's natural barriers and further muck up the West Coast's marine environments. And more invasive species could be hitching rides on tsunami debris expected to arrive in the weeks and months to come."

Publicly Funded GMO Research Facing Destruction In Italy 245

ChromeAeonium writes "Shortly after the events in Rothamsted Research in the UK, where a publicly funded trial of wheat genetically engineered to repel aphids was threatened by activists with destruction and required police protection, another publicly funded experiment involving genetically engineered crops faces possible destruction (original in Italian). The trial, which is being conducted by researchers at the University of Tuscia in Italy on cherries, olives, and kiwis genetically engineered to have traits such as fungal disease resistance, started three decades ago. When field research of GE plants was banned in Italy in 2002, the trial received an extension to avoid being declared illegal, but was denied another in 2008, and following a complaint from the Genetic Rights Foundation, now faces destruction on June 12th, despite appeals from scientists. The researchers claim that the destruction is scientifically unjustifiable (only the male kiwis produce transgenic pollen and their flowers are removed) and wish to gather more information from the long running experiment."
