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

Only 36 Percent of Indian Engineers Can Write Compilable Code, Says Study

New submitter troublemaker_23 quotes a report from ITWire: Only 36% of software engineers in India can write compilable code based on measurements by an automated tool that is used across the world, the Indian skills assessment company Aspiring Minds says in a report. The report is based on a sample of 36, 800 from more than 500 colleges across India. Aspiring Minds said it used the automated tool Automata which is a 60-minute test taken in a compiler integrated environment and rates candidates on programming ability, programming practices, run-time complexity and test case coverage. It uses advanced artificial intelligence technology to automatically grade programming skills. “We find that out of the two problems given per candidate, only 14% engineers are able to write compilable codes for both and only 22% write compilable code for exactly one problem, ” the study said. It further found that of the test subjects only 14.67% were employable by an IT services company. When it came to writing fully functional code using the best practices for efficiency and writing, only 2.21% of the engineers studied made the grade. Read more of this story at Slashdot.

A single autonomous car could greatly reduce man-made traffic

Traffic. We all hate it, but what can honestly be done to significantly reduce it? Well, according to an experiment conducted by the university of Illinois, simply introducing a few self-driving cars to roads could be the answer. Conducting experiments in Tucson, Arizona the team discovered that even adding a single autonomous vehicle to the roads can massively reduce traffic. They programmed a self-driving car to loop a track continuously and then added 20 other human-driven cars to the mix. While humans somehow naturally create stop-and-go traffic even without lane changes or other disruptions, thanks to the robotic racer, both traffic and fuel consumption were reduced by 40 percent. This isn’t the first example of modern tech helping to reduce congestion. With fixed traffic sensors widely swapped for navigation systems using GPS data, Professor Daniel B. Work believes that automated cars could be the next step — replacing the traffic-reducing variable speed limits. The next stage of the experiment is to test autonomous cars in situations where both human and AI drivers have to change lanes. From our experience with freeways, we already feel bad for the robot cars. Still, this isn’t the only way that drivers can use automation to reduce traffic. With the margin of human error being so high, the same study suggests that even existing tech like adaptive cruise control has the power to greatly reduce the amount of traffic on our roads. With many people understandably wary at the prospect of roads completely ruled by automated cars, the idea of mixing a few with regular vehicles seems like a good way to pilot the risky tech.

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.

‘Guardians of the Galaxy’ team says why it used Red’s 8K camera

When director James Gunn revealed that Guardians of the Galaxy Vol. 2 would be the first movie shot with Red’s 8K Weapon camera , he triggered a bit of speculation: what prompted the move beyond the incredibly high resolution? You might have a better answer today. Red has posted a behind-the-scenes look at the movie that, to no one’s surprise, talks a lot about why the Vol. 2 team shot with such relatively exotic gear. And no, it’s not just about that picture quality. As director of photography Henry Braham summarizes: the Weapon is a “large format” camera that’s simultaneously “tiny.” That let the crew shoot very detailed imagery regardless of the shot — important for a CG-heavy movie, since it maintains a consistently sharp look. They could use the same cameras for handheld close-ups or unusual rigs, such as a spider rig that flies along a wire. In short, they didn’t have to switch cameras or resort to convoluted setups. The behind-the-scenes video is undoubtedly a puff piece meant to sell you on both the camera and the movie. However, it’s also a hint as to where movie technology is going. You can expect 8K digital cameras to become more commonplace, of course, but they also promise more elaborate cinematography that might have been difficult just a few years ago. Source: Red

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…

Google’s mysterious Fuchsia OS looks like an Android re-do

When we last looked at Google’s Fuchsia operating system , it was very modest. While it was designed for everything from Internet of Things devices to PCs, there wasn’t even a graphical interface to show. Well, things have… evolved. Ars Technica has revisited Fuchsia several months later, and it now touts an interface (nicknamed Armadillo) that makes it clear this isn’t just some after-hours experiment. It’s only a set of placeholders at the moment, but it gives you a good idea as to what to expect. The home screen is a large, vertically scrolling list of cards for “stories, ” or collections of apps and OS components that work together to complete a given task. There’s also a Google Now -style section that has “suggestion” cards for tasks — use them and you’ll either add to an existing story or create a new one. The prototype UI also includes a simple split-screen interface, and scales up to tablet size. Fuchsia isn’t based on Linux, like Android or Chrome OS, but it still uses open source code that would let anyone tinker with the inner workings. Apps, meanwhile, are built using Google’s Flutter kit, which lets developers write both Android and iOS apps. Things are clearly coming along. But there’s one overriding question: just what role will Fuchsia have? Google’s Travis Geiselbrecht stresses that this “isn’t a toy thing, ” but there’s no public strategy. Ars speculates that Google is treating this as a sort of Android re-do: what if the company could design a platform while dumping all the technology it no longer needs or wants, such as Linux or any traces of Java ? The use of Flutter would let you run Android apps until there’s broader software support. It might take years before Fuchsia is ready for public use, assuming that’s the ultimate plan, but there could be a day where Android is no longer the center of Google’s computing universe.

Mac users installing popular DVD ripper get nasty backdoor instead

(credit: Patrick Wardle ) Hackers compromised a download server for a popular DVD-ripping software named HandBrake and used it to push stealthy malware that stole victims’ password keychains, password vaults, and possibly the master credentials that decrypted them, security researchers said Monday. Over a four-day period ending Saturday, a download mirror located at download.handbrake.fr delivered a version of the video conversion software that contained a backdoor known as Proton, HandBrake developers warned over the weekend . At the time that the malware was being distributed to unsuspecting Mac users, none of the 55 most widely used antivirus services detected it. That’s according to researcher Patrick Wardle , who reported results here and here from the VirusTotal file-scanning service. When the malicious download was opened, it directed users to enter their Mac administer password, which was then uploaded in plain text to a server controlled by the attackers. Once installed, the malware sent a variety of sensitive user files to the same server. In a blog post published Monday morning , Thomas Reed, director of Mac offerings at antivirus provider Malwarebytes, wrote: Read 5 remaining paragraphs | Comments
