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.

An anonymous reader writes: A recently released draft of the National Institute of Standards and Technology’s digital identity guidelines has met with approval by vendors. The draft guidelines revise password security recommendations and altering many of the standards and best practices security professionals use when forming policies for their companies. The new framework recommends, among other things: “Remove periodic password change requirements.” There have been multiple studies that have shown requiring frequent password changes to actually be counterproductive to good password security, said Mike Wilson, founder of PasswordPing. NIST said this guideline was suggested because passwords should be changed when a user wants to change it or if there is indication of breach. Read more of this story at Slashdot. 
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
