Over 7,000 Bodies May Be Buried Beneath Mississippi University

In what sounds like a clichéd horror movie premise, a recent investigation suggests as many as 7, 000 bodies are buried across 20 acres at the Mississippi Medical Center Campus—the former site of the state’s first mental institution. Officials at the university now face the grim task of pulling 100-year-old bodies… Read more...

Watch this self-healing material handle a bullet

NASA-funded research has created a material that could self-heal in seconds. Two layers of solid polymer sandwich a gel that with an ingredient that solidifies on contact with air (i.e. when one or both of the outer layers is damaged). This differs from other approaches that rely on a mostly-liquid compound , or similar, slower techniques . The protective applications in space craft (like the ISS) are obvious, and could add a vital line of defense against dangerous debris. The ISS already has shields to protect it, but reactive armour in the event of damage would be even more reassuring. Back down here on earth, the same material could be used in cars, pips, containers and even phones ( beyond scratches ). Watch the material get shot and self-heal in the video below.

Arizona will get non-stop clean energy from hot air drafts

Many green energy sources only generate power in a narrow range of conditions. Solar panels won't work when it's dark, for instance, and wind turbines are useless when everything is still. If Solar Wind Energy Tower has its way, though, we'll soon get clean electricity around the clock. It recently received permission to build a tower in San Luis, Arizona that produces power through hot air downdrafts; water injected at the top of the tower cools the desert winds, dragging them toward turbines at the bottom. Since it's almost always hot in the area, the plant should run all day and night for much of the year. An ideal summer day could have it churning out a healthy 1, 250 megawatts per hour. The downdraft tower should be ready for action in 2018, and Solar Wind Energy Tower hopes to license the technology to others. As you might imagine, the need for a hot climate is going to narrow the customer list -- you won't see this system in more temperate regions. However, it could be a boon to both the southern US as well as Africa, the Middle East and other places where heat is far more abundant than eco-friendly energy.

Windows 10 hits 500 million devices, growing by two-thirds in a year

SEATTLE—At its Build developer conference, Microsoft has announced that Windows 10 has now passed 500 million monthly active devices. Little over a year ago, the company said that the operating system had reached 300 million systems . As the operating system nears the end of its second full year on the market, it's clear that it's going to fall a long way short of the company's original estimates. At launch, the ambition was to reach 1 billion devices over the first two to three years of availability, but this estimate assumed that Windows 10 Mobile would be a going concern, selling something of the order of 50 million or more devices a year.

Lasers Unearth Lost ‘Agropolis’ of New England

sciencehabit writes "Hidden ruins are customary in the wild jungles of South America or on the white shores of the Mediterranean Sea. Now, researchers have uncovered a long-lost culture closer to Western civilization — in New England. Using aerial surveys created by LiDAR, a laser-guided mapping technique, the team detected the barely perceptible remnants of a former 'agropolis' around three rural New England towns (abstract). Near Ashford, Connecticut, a vast network of roads offset by stone walls came to light underneath a canopy of oak and spruce trees. More than half of the town has become reforested since 1870, according to historical documents, exemplifying the extent of the rural flight that marked the late 1800s. Some structures were less than 2 feet high and buried in inaccessible portions of the forest, making them essentially invisible to on-the-ground cartography." Read more of this story at Slashdot.

Scientists stunned by new findings about salt’s effects on body

Conventional wisdom: If you eat a lot of salt, you will get thirsty to dilute the sodium level in your blood. The excess salt will be excreted in your urine. But a new study of Russian cosmonauts is challenging this long-held belief. When the cosmonauts ate more salt, the became less thirsty. And their appetite increased - they had to eat 25 percent more to maintain their weight. From the New York Times : The crew members were increasing production of glucocorticoid hormones, which influence both metabolism and immune function. To get further insight, [Dr. Jens Titze, now a kidney specialist at Vanderbilt University Medical Center and the Interdisciplinary Center for Clinical Research in Erlangen, Germany] began a study of mice in the laboratory. Sure enough, the more salt he added to the animals’ diet, the less water they drank. And he saw why. The animals were getting water — but not by drinking it. The increased levels of glucocorticoid hormones broke down fat and muscle in their own bodies. This freed up water for the body to use. But that process requires energy, Dr. Titze also found, which is why the mice ate 25 percent more food on a high-salt diet. The hormones also may be a cause of the strange long-term fluctuations in urine volume. Scientists knew that a starving body will burn its own fat and muscle for sustenance. But the realization that something similar happens on a salty diet has come as a revelation. https://youtu.be/aJEzl31zL-I

Xbox Play Anywhere: buy the game once, play on Xbox One and PC (multiplayer...

(credit: Microsoft) When announcing  Gears of War 4 at its E3 event today, Microsoft unveiled a new gaming feature called Xbox Play Anywhere. Essentially, this initiative allows a gamer to purchase a title once but still have the option to play on console  and  PC.

Android Stagefright Bug Required 115 Patches, Millions Still At Risk

eWeek reports that "hundreds of millions of users remain at risk" one year after Joshua Drake discovered the Stagefright Android flaw. Slashdot reader darthcamaro writes: A year ago, on July 27, 2015 news about the Android Stagefright flaw was first revealed with the initial reports claiming widespread impact with a billion users at risk. As it turns out, the impact of Stagefright has been more pervasive...over the last 12 months, Google has patched no less than 115 flaws in Stagefright and related Android media libraries. Joshua Drake, the researcher who first discovered the Stagefright flaw never expected it to go this far. "I expected shoring up the larger problem to take an extended and large effort, but I didn't expect it to be ongoing a year later." Drake believes targeted attacks use Stagefright vulnerabilities on unpatched systems, but adds that Android's bug bounty program appears to be working, paying out $550, 000 in its first year.

Windows 10 Timeline remembers everything you did on your PC

One of the more intriguing features Microsoft will include in this fall's Windows 10 Creators Update is Timeline. As the name suggests, it's a way for you to move backwards in time and see things you were working on in the past and resume what you were doing. Microsoft described it as a visual timeline of everything you were doing on your computer, and you can jump back into files, applications and websites where you left off. Introducing Timeline. Easily jump back in time to continue where you left off. #Windows10 #MSBuild pic.twitter.com/e3gxhXnp6W — Windows (@Windows) May 11, 2017 Timeline lives in the Windows app switcher. When you click it, you'll see your active apps, but below that you'll see what you were running earlier in the day. Clicking down on one of those things that you were using earlier will pop it open just as you were using it before. This works across multiple devices, as well -- when you open up another Windows device where you're signed in, you can resume the tasks you were using before. This will even work across other devices like an iPhone using the Cortana app. If you're somewhere where you have Cortana, it'll prompt you to continue working on whatever you were doing before. If you don't have the specific app installed on your phone, it'll help point you to the right app as well. At first glance, it sounds a little bit like the Time Machine backup feature that Apple has included in macOS for years now. But Time Machine is more of a file backup system that lets you go back and see earlier versions of files that you might want to restore. Microsoft's Timeline covers applications and websites as well as just files, and it doesn't require an external hard drive, as it's not really a true backup system in the way Time Machine is. Indeed, Timeline appears more like Microsoft's answer to Continuity, a feature Apple build into macOS and iOS that lets you pick up and resume work across whatever Apple device you're using. Timeline is just one feature in the forthcoming Creators Update, which features a host of tools for using Microsoft's software and services across devices. The "Microsoft Graph" set of APIs will let you pick up and continue work across multiple devices and will iOS and Android as well as Windows. It'll also let you have a "universal clipboard" across your devices. Click here to catch up on the latest news from Microsoft Build 2017.

Toshiba Plans To Ship a 1TB Flash Chip To Manufacturers This Spring

Lucas123 writes: Toshiba has begun shipping samples of its third-generation 3D NAND memory product, a chip with 64 stacked flash cells that it said will enable a 1TB chip shipping later this spring. The new flash memory product has 65% greater capacity than the previous generation technology, which used 48 layers of NAND flash cells. The chip will be used in data centers and consumer SSD products. The technology announcement comes even as suitors are eyeing buying a majority share of the company's memory business. Along with a previous report about Western Digital, Foxxcon, SK Hynix and Micron Technology have now also thrown their hats in the ring to purchase a majority share in Toshiba's memory spin-off, according to a new report in the Nikkei's Asian Review.
