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

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