This Synthetic Bone Implant Could Replace Painful Marrow Transplants

Thanks to advances in medicine, bone marrow transplants are no longer the last resorts they one were. Every year, thousands of marrow transplants are performed, a common treatment for ailments from bone marrow disease to leukemia. But because they first require a patient undergo radiation to kill off any existing bone… Read more…

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

Antarctica’s ‘Dragon Skin’ Ice Is Incredible

Dragon skin ice sounds like something you’d encounter beyond The Wall in the Game of Thrones fantasy realm. But good news nerds, you can find this magical-sounding stuff right here on Earth—though you’ve gotta be lucky, and willing to travel to some of the most hostile environments on the planet. Like the team of… Read more…

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.

NIST’s Draft To Remove Periodic Password Change Requirements Gets Vendors’ Approval

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.

235 apps attempt to secretly track users with ultrasonic audio

Ultrasonic beacons ( previously , previously ) let advertisers build an idea of when and where you use your devices: the sound plays in an ad on one device, and is heard by other devices. This way, they can associate two gadgets with a single user, precisely geolocate devices without aGPS, or even build graphs of real-world social networks. The threat was considered more academic than some, but more than 200 Android apps were found in the wild using the technique . In research sponsored by the German government [PDF], a team of researchers conducted extensive tests across the EU to better understand how widespread this practice is in the real world. Their results revealed Shopkick ultrasonic beacons at 4 of 35 stores in two European cities. The situation isn’t that worrisome, as users have to open an app with the Shopkick SDK for the beacon to be picked up. In the real world, this isn’t an issue, as store owners, advertisers, or product manufactures could incentivize users to open various apps as a way to get discounts. From the paper: While in April 2015 only six instances were known, we have been able to identify 39 further instances in a dataset of about 1,3 million applications in December 2015, and until now, a total of 234 samples containing SilverPush has been discovered. We conclude that even if the tracking through TV content is not actively used yet, the monitoring functionality is already deployed in mobile applications and might become a serious privacy threat in the near future Apparently it’s not very effective—consumer speakers and mics aren’t designed with ultrasonic use in mind and the authors say noise, audio compression and other factors “significantly affects the feasibility” of the technology—but the intent is clearly there on the part of advertisers and appmakers to make a stab at it. Annoyingly, there doesn’t seem to be a list of the apps that are doing this, but there is a reference to a McDonalds app. If an app asks for access to your device’s microphone, camera, etc., and you don’t know why, delete the app.
