Smithsonian Releases 128-Year-Old Recording of Alexander Graham Bell 122

redletterdave writes "Thanks to a newly developed audio extraction technology called optical scanning, the Smithsonian was able to recover the voice of Alexander Graham Bell from one of his hundreds of discs he donated to the museum, which were once considered 'mute artifacts.' Since many of the collected recordings are very fragile due to their age and experimental nature, optical scanning is a non-invasive procedure that creates a high-resolution digital map of the disc or cylinder, which is then reconstructed and used to simulate the motion of a stylus moving through its grooves to reproduce the original audio content. Bell, who created this recording on a wax and cardboard disc on April 15, 1885, can be heard clearly saying, 'In witness whereof — hear my voice, Alexander Graham Bell.'"

Scientists May Have Detected Neutrinos From Another Galaxy 151

The Bad Astronomer writes "A experiment called IceCube — consisting of sensitive light detectors buried deep in the Antarctic ice — has detected two ultra-high-energy neutrinos, each with over a peta-electronVolt of energy (a quadrillion times the energy of a visible light photon), the highest energy neutrinos ever seen. The two events, nicknamed Bert and Ernie, have a 99% chance of originating outside our galaxy, likely created either by a supermassive black hole or an exploding gamma-ray burst."

Old Educational Computer Resurrected As a Spreadsheet 37

An anonymous reader writes "Back in the '60s, Bell Labs created a 'paper computer' called CARDIAC so students could learn the fundamentals of computers. Dr. Dobb's recreates the paper computer in an Excel spreadsheet and hints they will show how it gets ported to an FPGA in future installments."

Harvard To Close New England Primate Research Center 100

sciencehabit writes "Citing an increasingly bleak outlook for federal research funding, Harvard Medical School is shutting down its major primate center, which has recently experienced the departure of several key scientists and an investigation into its handling of animals. In the announcement, which surprised many primate researchers, the school said it will not seek to renew the New England Primate Research Center's (NEPRC's) 5-year grant from the National Institutes of Health (NIH) and will 'wind down operations' at the center in Southborough, Massachusetts, over the next 2 years. The center, which has a nearly 50-year history, had done groundbreaking work on an AIDS vaccine and developed animal models for diseases such as Parkinson's, among other accomplishments."

Device Keeps Liver Alive Outside Body For 24 Hours 62

kkleiner writes "A new device will keep a liver alive outside of the human body for up to 24 hours. Developed at Oxford, the OrganOx circulates oxygenated red bloods cells and nutrients through the liver while maintaining the proper temperature. Doctors estimate that this new technique could double the number of livers available, saving the lives of thousands who die every year awaiting transplant."

NASA Lets Us Watch the Sun Spin For 3 Years In 4 Minute Video 34

An anonymous reader writes "Back in February 2010 NASA launched the Solar Dynamics Observatory–a 3-axis stabilized satellite and fully redundant spacecraft. The aim of the SDO is to monitor solar activity and see how that impacts space weather. As part of its observations, the SDO captures an image of the Sun every 12 seconds using the onboard Atmospheric Imaging Assembly, but varies those shots across 10 different wavelengths. NASA has now collected three years worth of image data from the SDO and has put together a video letting us see the Sun spin in all its glory." If you watch closely, you can see individual frames containing the Moon and Venus.

Modelling Reveals Likely Spread of New H7N9 Avian Flu 102

ananyo writes "With Taiwan announcing the first case of H7N9 avian flu outside mainland China, researchers have revealed how the virus may spread in China — and beyond. The projections use risk maps developed for human infection by another, well-established avian flu — H5N1. Indeed, when human cases of H7N9 are overlaid on a risk map, they appear to fall within the highest risk areas for H5N1. The map suggests that high-risk areas for H7N9 might include Shandong province (where the first case was reported 23 April) and a belt extending around the Bohai sea to Liaoning province in the north. Though there has been no evidence of sustained human-to-human spread of H7N9 so far, researchers have analyzed airline passenger data for China. Eastern China — the epicenter of the current the H7N9 outbreak — is one of the world's busiest hubs for airline traffic. From the Nature story: 'A quarter of the global population outside of China lives within two hours of an airport with a direct flight from the outbreak regions, and 70% if a single connecting flight is included.'"

LHCb Experiment Observes New Matter-Antimatter Difference 129

An anonymous reader writes "Matter and antimatter are thought to have existed in equal amounts at the beginning of the Universe, but today the Universe appears to be composed essentially of matter. By studying subtle differences in the behavior of particles and antiparticles, experiments at the LHC are seeking to cast light on this dominance of matter over antimatter. Now the LHCb experiment has observed a preference for matter over antimatter known as CP-violation in the decay of neutral B0s particles. The results are based on the analysis of data collected by the experiment in 2011."

'Green' Galaxy Recycles Gas, Supercharges Star Birth 36

astroengine writes "In a galaxy, far, far away (6 billion light-years away to be precise), the most efficient star 'factory' has been discovered. Called SDSSJ1506+54, this galaxy generates a huge quantity of infrared radiation, the majority being generated by a compact region at its core. NASA's Wide-field Infrared Survey Explorer first spotted the galactic oddity and Hubble confirmed the maelstrom of stellar birthing near its core. But the most amazing thing? This galaxy is the 'greenest' factory yet discovered — it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste. 'This galaxy is remarkably efficient,' said lead scientist Jim Geach of McGill University in a NASA news release. 'It's converting its gas supply into new stars at the maximum rate thought possible.'"

Play Tetris To Fix Your Lazy Eye 88

MightyMait writes "A study from a team at McGill University has found Tetris to be a good treatment for lazy eye. 'Armed with a special pair of video goggles they set up an experiment that would make both eyes work as a team. Nine volunteers with amblyopia were asked to wear the goggles for an hour a day over the next two weeks while playing Tetris, the falling building block video game. The goggles allowed one eye to see only the falling objects, while the other eye could see only the blocks that accumulate on the ground in the game. For comparison, another group of nine volunteers with amblyopia wore similar goggles but had their good eye covered, and watched the whole game through only their lazy eye. At the end of the two weeks, the group who used both eyes had more improvement in their vision than the patched group (abstract).' As someone born with crossed-eyes who underwent surgery as an infant and has lived with a lazy eye his whole life (without 3-D vision), the prospect of fixing my vision by playing Tetris is an enticing one."

Radioactive Bacteria Attack Cancer 53

ananyo writes "Two dangerous things together might make a medicine for one of the hardest cancers to treat. In a mouse model of pancreatic cancer, researchers have shown that bacteria can deliver deadly radiation to tumours — exploiting the immune suppression that normally makes the disease so intractable. The researchers coated the bacterium Listeria monocytogenes with radioactive antibodies and injected the bacterium into mice with pancreatic cancer that had spread to multiple sites. After several doses, the mice that had received the radioactive bacteria had 90% fewer metastases compared with mice that had received saline or radiation alone."

Ask Slashdot: Science Books For Middle School Enrichment? 203

new submitter heybiff writes "It is the time of year where students are scrambling for extra credit assignments to boost grades. As a middle school science teacher, I want to accommodate them, while still keeping science involved; and book reports are a popular activity in my school. Unfortunately, I have only been able to come up with a short list of science related books that a 11-14 year old would or could read in their free time: Ender's Game, Hitchhiker's Guide. What books would you recommend as a good read for an extra credit book report, that would still involve a strong science twist or inspire a student's interest in science? The book must be in print, science related, fiction or non-fiction, and not be overtly objectionable or outright banned. I look forward to the submissions." "Outright banned" actually seems a rich vein on which to draw; note that not even Ender's Game is safe.

Viruses From Sewage Contaminate Deep Well Water 93

First time accepted submitter ckwu writes "Scientists once thought that pathogens could not reach drinking water wells sunk into deep, protected groundwater aquifers. Nevertheless, over the past decade, researchers have identified diarrhea-causing viruses at a handful of deep bedrock well sites in the U.S. and Europe. Now, researchers report where these pathogenic viruses may have originated. The viruses appear to seep from sewer pipes and then swiftly penetrate drinking water wells. Experts recommend that public water systems might need to start testing for viruses on a routine basis."

Protesting Animal Testing, Intruders Vandalize Italian Lab 285

ananyo writes "Activists occupied an animal facility at the University of Milan, Italy, at the weekend, releasing mice and rabbits and mixing up cage labels to confuse experimental protocols. Researchers at the university say that it will take years to recover their work. Many of the animals at the facility are genetic models for psychiatric disorders such as autism and schizophrenia. Some of the mice removed by activists were delicate mutants and immunosuppressed 'nude' mice, which die very quickly outside controlled environments. No arrests have been made following the 12-hour drama, which took place on Saturday, although the university says that it will press charges against the protesters. The attack was staged by the animal-rights group that calls itself Fermare Green Hill (or Stop Green Hill), in reference to the Green Hill dog-breeding facility near Brescia, Italy, which it targets for closure."

Bigelow Aerospace Investigating Feasibility of Moon Base for NASA 140

littlesparkvt writes in with a bit from Space Industry News about Bigelow Aerospace's plans for the moon: "NASA and Bigelow Aerospace are in the initial planning phases for a moon base. 'As part of our broader commercial space strategy, NASA signed a Space Act Agreement with Bigelow Aerospace to foster ideas about how the private sector can contribute to future human missions,' Said David Weaver NASA Associate Administrator for the Office of Communications." Bigelow will be performing the study for free too. Robert Bigelow chatted with a radio host a few weeks ago about Bigelow's long-term space plans. They include refueling depots and a commercial moon base, since NASA isn't planning to go there.

Some Windows XP Users Can't Afford To Upgrade 953

colinneagle writes "During a recent trip to an eye doctor, I noticed that she was still using Windows XP. After I suggested that she might need to upgrade soon, she said she couldn't because she couldn't afford the $10,000 fee involved with the specialty medical software that has been upgraded for Windows 7. Software written for medical professionals is not like mass market software. They have a limited market and can't make back their money in volume because there isn't the volume for an eye doctor's database product like there is for Office or Quicken. With many expecting Microsoft's upcoming end-of-support for XP to cause a security nightmare of unsupported Windows devices in the wild, it seems a good time to ask how many users may fall into the category of wanting an upgrade, but being priced out by expensive but necessary third-party software. More importantly, can anything be done about it?"

IBM Models Human Blood System To Build Solar Power Prototype 87

coondoggie writes "IBM today said its researchers are developing a solar power system that concentrates solar radiation 2,000 times by using a human-blood supply modeled way of cooling and converting 80% of Sun's heat into useful energy. IBM says the system can also desalinate water and cool air in sunny, remote locations where such systems are often in short supply."

Samsung Researching How To Let You Control Your Phone With Your Brain 80

Nerval's Lobster writes "Samsung is testing a way to control your mobile device with your brainwaves. If that project succeeds, it would truly be a case of science fiction brought to real life. According to MIT Technology Review, Samsung's Emerging Technology Lab is collaborating with Roozbeh Jafari, assistant professor of electrical engineering at the University of Texas, Dallas, on the early-stage research. That research involves placing a cap 'studded with EEG-monitoring electrodes' atop the head of a convenient subject, who then concentrates on an onscreen icon blinking at a particular rate. Concentrate hard enough, and the subject can launch and interact with applications. However, Samsung also indicated that mind-controlled mobile devices are quite a ways off, if they ever appear in a market-ready form at all. 'Several years ago, a small keypad was the only input modality to control the phone, but nowadays the user can use voice, touch, gesture, and eye movement to control and interact with mobile devices,' Insoo Kim, Samsung's lead researcher, told the Review. 'Adding more input modalities will provide us with more convenient and richer ways of interacting with mobile devices.' In any case, it's a crazy concept, the sort of thing Philip K. Dick might have written up as a short story; but it's one evidently grounded in reality."

Physicist Proposes New Way To Think About Intelligence 233

An anonymous reader writes "A single equation grounded in basic physics principles could describe intelligence and stimulate new insights in fields as diverse as finance and robotics, according to new research, reports Inside Science. Recent work in cosmology has suggested that universes that produce more entropy (or disorder) over their lifetimes tend to have more favorable properties for the existence of intelligent beings such as ourselves. A new study (pdf) in the journal Physical Review Letters led by Harvard and MIT physicist Alex Wissner-Gross suggests that this tentative connection between entropy production and intelligence may in fact go far deeper. In the new study, Dr. Wissner-Gross shows that remarkably sophisticated human-like "cognitive" behaviors such as upright walking, tool use, and even social cooperation (video) spontaneously result from a newly identified thermodynamic process that maximizes entropy production over periods of time much shorter than universe lifetimes, suggesting a potential cosmology-inspired path towards general artificial intelligence."

Privately Built Antares Test Flight Successfully Launched From Virginia 85

After high winds (up to 140mph) delayed yesterday's scheduled launch (itself a re-do because of a cabling problem), Orbital Science's Antares rocket has made it to space. This launch was a test run, but Antares is intended to launch supplies to the ISS. reports: "The third try was the charm for the private Antares rocket, which launched into space from a new pad at NASA's Wallops Flight Facility, its twin engines roaring to life at 5 p.m. EDT (2100 GMT) to carry a mock cargo ship out over the Atlantic Ocean and into orbit. The successful liftoff came after two delays caused by a minor mechanical glitch and bad weather." Congratulations to all involved.
