A Russian spacecraft has successfully delivered new supplies to the ISS. Crucially, its payload is meant to prevent a repeat of the aborted spacewalk of earlier this month. Says the article:: "The cargo ship is loaded with nearly 3 tons (2.7 tonnes) of food, fuel, hardware and science experiment equipment for the six-person crew of the station's Expedition 36 mission. Among its cargo is a set of tools intended to help the astronauts investigate and patch up the spacesuit that malfunctioned during a July 16 spacewalk outside the orbiting laboratory."

An anonymous reader writes "The 233-year old American Academy of Arts and Sciences has announced that its longtime President and Chief Executive, Leslie Cohen Berlowitz, has agreed to resign effective at the end of this month following an investigation of charges of resume embellishment and other misconduct. Berlowitz falsely claimed to have received a doctorate from New York University, and has also been criticized for her behavior towards scholars and subordinates, and for her compensation package ($598,000 for 2012) relative to the size of the non-profit organization she led. The Academy, based in Cambridge MA, was founded during the American Revolutionary War and is one of the most prestigious honorary societies for the American intellectual elite, extending across math and science, arts and letters, business, law and public affairs. The active membership rolls contain people you've heard of; the incoming class list provides a more manageable glimpse of the society's breadth."
An anonymous reader writes with an optimistic, present-tense summary of a crowdfunding project to explore Earth's deep ocean: "The Ictineu 3 will be the 10th deepest diving submersible in the world when it is launched later this year. Compared to its deep diving peers, including Russia's Mirs, Japan's Shinkai 6500, the U.S.'s Alvin,and Cameron's Deep Sea Challenger submersibles, the Ictineu 3 was developed on a shoestring budget. The management partners are self-taught, without formal engineering education. Instead of massive government grants, the project has been funded by a trickle of small grants, sponsorships, and private donors. Along with Karl Stanley, the Ictineu team are heroes to the DIY submariners of the world."
An anonymous reader writes "IEEE Spectrum has a story about a robot that uses infra red and ultrasound to image veins, picks the one with best bloodflow, and then sticks a needle in. (video included). Veebot started as an undergrad project and the creators are aiming for better performance than a human phlebotimist before going for clinical trials. Robodracula anyone?"
sciencehabit writes "Scientists have spotted swirling patterns in the radiation lingering from the big bang, the so-called cosmic microwave background. The observation itself isn't Earth-shaking, as researchers know that these particular swirls or 'B-modes' originated in conventional astrophysics, but the result suggests that scientists are closing in on a much bigger prize: B-modes spawned by gravity waves that rippled through the infant universe. That observation would give them a direct peek into the cosmos' first fraction of a second and possibly shed light on how it all began."
Daniel_Stuckey writes "Researchers at National Taiwan University have created a tooth-embedded sensor that will catch you in an unhealthy act, whatever it may be, and lets your doctor know so he can shame you during your next checkup. The sensor consists of a tiny circuit that fits inside a tooth cavity and can be rigged into dentures and dental braces. The circuit is able to recognize the jaw motions of drinking, chewing, coughing, speaking, and smoking, and the results get sent directly to your doctor's smartphone."
cylonlover writes "The Honourable Usain Bolt (Order of Jamaica; Commander of the Order of Distinction) is often held out as the world's fastest man. The reigning Olympic champion in the 100-meter and 200-meter sprints as well as a member of the Olympic champion 4x100 meter relay team, Bolt is the first man to win six Olympic gold medals in sprinting, and is a five-time world champion. Long and lanky at 6 ft 5 in (2 m) tall, he towers above the (mostly) much shorter sprinters. How has he managed to come out on top for the past five years? A team of physicists from the Universidad Nacional Autonoma de Mexico (UNAM) has analyzed Bolt's past performances in the 100-meter sprint to understand what makes a record-breaker."
sciencehabit writes "For Ved Chirayath, a graduate student and amateur fashion photographer, a photo project that involved NASA researchers dressed as Vikings was just a creative way to promote space science. 'I started this project hoping maybe one day some kid will look at it and say, 'I want to work for NASA,' ' says Chirayath, a student at Stanford University in Palo Alto, California, who also works nearby at NASA's Ames Research Center. He never suspected that his fanciful image would put him in the crosshairs of a government waste investigation triggered by a senior U.S. senator." The project was funded by an outside art grant. The best part: the investigation into the non-existent waste probably cost more than the "waste" would have were it funded by NASA in the first place.
dcblogs writes "The National Oceanic and Atmospheric Administration (NOAA) Thursday switched on two new supercomputers that are expected to improve weather forecasting. The supercomputers are each 213 teraflops systems, running a Linux operating system on Intel processors. The U.S. is paying about $20 million a year to operate the leased systems. The NWS has a new hurricane model, Hurricane Weather Research and Forecasting (HWRF), which is 15% more accurate in day five of a forecast both for forecast track and intensity. That model is now operational and running on the new systems. In nine month, NWS expects to improve the resolution of the system from 27 kilometers to 13 kilometers. The European system, credited with doing a better job at predicting Sandy's path, is at 16 kilometers resolution. In June, the European forecasting agency said it had a deal to buy Cray systems capable of petascale performance."
sciencehabit writes "Call it 'Total Recall' for mice. A group of neuroscientists say that they've identified a potential mechanism of false memory creation and have planted such a memory in the brain of a mouse. With this knowledge, neuroscientists can start to figure out how many neurons it takes to give us the perception of what's around us and what goes on in our neural wiring when we remember—or misremember—the past."
Lasrick writes "Interesting opinion piece that explains successes and holes in the U.S. system of detecting and responding to pandemics: 'In April 2009, following an experimental protocol, staff members at a Navy lab in San Diego tested specimens from two patients using a new diagnostic device. Both tested positive for influenza, but, oddly, neither specimen matched the influenza A subtypes that are known to infect humans. This finding raised suspicions, and so the samples were sent to the US Centers for Disease Control and Prevention (CDC). Further tests would reveal that these two patients were the first reported cases of a novel H1N1 influenza virus that would cause a global pandemic in 2009. In many respects, the Navy lab's discovery of H1N1 is a success story for US efforts to boost its biosurveillance capabilities.'"
An anonymous reader writes "Regeneration is one of the most useful skills that an organism can possess. Lizards can regrow their tails and starfish can regrow and entire part of themselves if they're cut to pieces. Yet scientists have long wondered why some creatures possess this ability while others don't. That's why they decided to examine the process of regeneration, looking at the masters of this particular adaptation: flatworms."
dryriver writes "Psychopaths do not lack empathy, rather they can switch it on at will, according to new research. Placed in a brain scanner, psychopathic criminals watched videos of one person hurting another and were asked to empathise with the individual in pain. Only when asked to imagine how the pain receiver felt did the area of the brain related to pain light up. Scientists, reporting in Brain, say their research explains how psychopaths can be both callous and charming. The team proposes that with the right training, it could be possible to help psychopaths activate their 'empathy switch', which could bring them a step closer to rehabilitation. Criminals with psychopathy characteristically show a reduced ability to empathise with others, including their victims. Evidence suggests they are also more likely to reoffend upon release than criminals without the psychiatric condition."
oritonic1 writes "During their long, cold winters, the Norwegian town of Rjukan doesn't enjoy much by way of daylight—so the town (population 3,386), installed three giant sun-tracking mirrors to shine a steady light over a 2000 square foot circle of the town square. From Popular Mechanics: 'Call it a mood enhancer. Or a tourist attraction. But the mirrors, which will be carried in via helicopter, will provide an oasis of light in an otherwise bleak location at the center of the 3500-population town. Three mirrors with a total surface area of about 538 square feet will sit at an angle to redirect winter sun down into the town, lighting up over 2150 square feet of concentrated space in the town square. A similar idea exists in the Italian village of Viganella, which has used brushed steel to reflect light since 2006.'"
notscientific writes "Each wolf has a unique howl, which scientists can now decipher through voice recognition (audio), allowing them to identify wolves individually. The scientists developed sound analysis code that can tell which wolf is howling with 100% accuracy. Previously, pitch was used to tell wolves apart, but these only achieved a relatively low accuracy rate. This sound analysis is important because it could well give researchers the first proper way to effectively monitor wolves in the wild. Interestingly, this research comes after the recent finding that dolphins have names for one another. In the case of wolves, their howls are essentially their names."
cylonlover writes "Reports that the High Frequency Active Auroral Research Program (HAARP) had been shut down permanently were apparently a bit premature. According to HAARP program manager James Keeney, the facility is only temporarily off the air while operating contractors are changed. So why does anyone care? Despite being associated with various natural disasters over the past two decades by the conspiracy fringe, HAARP is in reality a facility for studying the ionosphere. Gizmag takes a look at the goings on at HAARP – past, present, and future."
sciencehabit writes "It's the size of large rat, but it can reportedly withstand the weight of an adult man standing on its back. Meet the hero shrew, a molelike creature that owes its near-mythological status to a remarkable spine, thickened by extensions of bone that interlock like fingers. The structure was thought to be unique among mammals — until now. An international team of researchers in the village of Baleko, in the Democratic Republic of the Congo, made a surprising find: a slightly different shrew with a similarly 'heroic' backbone. Today in Biology Letters, they introduce Thor's hero shrew (S. thori), named for mammalogist Thorvald Holmes, but invoking the Norse god of strength. The researchers don't yet know how its strength compares to that of S. somereni. After exploring the shrews' swampy palm forests habitat, the researchers also have a new guess about why the spine evolved: They suggest that the creatures might wedge themselves between the trunk of a palm tree and the base of its leaves, then use the strength and flexion of their muscular spine to force open this crevice, revealing insect larvae—a food source that other animals can't access."
Nerval's Lobster writes "Astrophysicists at MIT and the Pawsey supercomputing center in Western Australia have discovered a whole new role for supercomputers working on big-data science projects: They've figured out how to turn a supercomputer into a router. (Make that a really, really big router.) The supercomputer in this case is a Cray Cascade system with a top performance of 0.3 petaflops — to be expanded to 1.2 petaflops in 2014 — running on a combination of Intel Ivy Bridge, Haswell and MIC processors. The machine, which is still being installed at the Pawsey Centre in Kensington, Western Australia and isn't scheduled to become operational until later this summer, had to go to work early after researchers switched on the world's most sensitive radio telescope June 9. The Murchison Widefield Array is a 2,000-antenna radio telescope located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia, built with the backing of universities in the U.S., Australia, India and New Zealand. Though it is the most powerful radio telescope in the world right now, it is only one-third of the Square Kilometer Array — a spread of low-frequency antennas that will be spread across a kilometer of territory in Australia and Southern Africa. It will be 50 times as sensitive as any other radio telescope and 10,000 times as quick to survey a patch of sky. By comparison, the Murchison Widefield Array is a tiny little thing stuck out as far in the middle of nowhere as Australian authorities could find to keep it as far away from terrestrial interference as possible. Tiny or not, the MWA can look farther into the past of the universe than any other human instrument to date. What it has found so far is data — lots and lots of data. More than 400 megabytes of data per second come from the array to the Murchison observatory, before being streamed across 500 miles of Australia's National Broadband Network to the Pawsey Centre, which gets rid of most of it as quickly as possible."
Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."
coolnumbr12 writes "A 2009 study (PDF) by the McAfee estimated that hacking costs the global economy $1 trillion. It turns out that number was a massive exaggeration by McAfee, a software security branch of Intel that works closely with the U.S. government at the local, state and federal level. A new estimate by the Center for Strategic and International Studies (and underwritten by McAfee) suggests the number is closer to closer to $300 billion (PDF), but even that much is uncertain. One of McAfee's clients, the Department of Defense, has used the $1 trillion estimate to argue for an expansion of cybersecurity, including 13 new teams dedicated to cyberwarfare. Despite the new data, Reuters said McAfee is still trying to exaggerate the numbers." The $1 trillion study has seen other criticism as well, so the new data is a step in the right direction.
