An anonymous reader writes Twitch today announced that the Justin.tv website, mobile apps, and APIs are no longer in service. A very simple explanation is given for the shutdown: since rebranding the company to Twitch Interactive in February 2014, all resources are now focused on Twitch.tv. The news today will almost certainly further fuel the rumors that Google is acquiring, or has already acquired, Twitch. Purchases are often followed by consolidation, as well as cutting off any excess limbs. Read more of this story at Slashdot.

yyzmcleod (1534129) writes The technology to 3D print a single part from multiple materials has been around for years, but only for polymer-based additive manufacturing processes. For metals, jobs are typically confined to a single powdered base metal or alloy per object. However, researchers at NASA’s Jet Propulsion Laboratory say they have developed a 3D printing technique that allows for print jobs to transition from one metal to another in a single object. From the article: In JPL’s technique, the build material’s composition is gradually transitioned as the print progresses. For example, the powdered build material might contain 97 percent titanium alloy and 3 percent stainless steel at the beginning of the transition. Then, in 1 percent increments between layers, the gradient progresses to 97 percent stainless steel and 3 percent Ti alloy by some defined point in the overall 3D printing process.

You eventually tune it out, but the constant whir of a desktop computer’s cooling fans can take a toll on your psyche. It’s like a buzzing mosquito that never strikes, and never stops. So the folks at a German company called Silent Power have created a compact desktop PC that trades noisy fans for a block of exposed copper foam that dissipates heat so effectively no fans are required.

If humanity hopes to realize its dreams of exploring the stars, we’re going to need to find ways to recreate life on Earth aboard a spaceship. Simply stockpiling enough vital supplies isn’t going to cut it, which is what led Julian Melchiorri , a student at the Royal College of Art, to create an artificial biological leaf that produces oxygen just like the ones on our home planet do.

This morning at the annual Research Faculty Summit, Microsoft showed off a pretty impressive advancement in its AI tech. An app, entitled Project Adam , is poised to identify all of its surroundings just like a Fire Phone without the merch hooks. The app is still in development but shows promising results. Read more… 
This is the USS Iowa, the first of the largest, most powerful battleship class ever in the United States Navy, equipped with nine 406mm cannons that could fire nuclear shells —the only American ship in history with this capability. This photo series is old but still stunning. Read more… 
astroengine writes: “A weird type of ‘hybrid’ star has been discovered nearly 40 years since it was first theorized — but until now has been curiously difficult to find. In 1975, renowned astrophysicists Kip Thorne, of the California Institute of Technology (Caltech) in Pasadena, Calif., and Anna Zytkow, of the University of Cambridge, UK, assembled a theory on how a large dying star could swallow its neutron star binary partner, thus becoming a very rare type of stellar hybrid, nicknamed a Thorne-Zytkow object (or TZO). The neutron star — a dense husk of degenerate matter that was once a massive star long since gone supernova — would spiral into the red supergiant’s core, interrupting normal fusion processes. According to the Thorne-Zytkow theory, after the two objects have merged, an excess of the elements rubidium, lithium and molybdenum will be generated by the hybrid. So astronomers have been on the lookout for stars in our galaxy, which is thought to contain only a few dozen of these objects at any one time, with this specific chemical signature in their atmospheres. Now, according to Emily Levesque of the University of Colorado Boulder and her team, a bona fide TZO has been discovered and their findings have been accepted for publication in the Monthly Notices of the Royal Astronomical Society Letters.” Read more of this story at Slashdot.
