Two of America’s top chipmakers have been ordered to stop selling some of their technology to China that can be used for artificial intelligence.

Nvidia (NVDA) and AMD (AMD) said Wednesday that they had been told by the US government to halt exports of certain high-performance chips to the world’s second largest economy.

In a regulatory filing, Nvidia said that it had been told by US officials that the requirement was due to a potential risk of the products being used by, or diverted to, a “military end user.”

(PhysOrg.com) — Sometimes total electrical isolation is a good thing — and that’s the idea behind a power-over-fiber (PoF) communications cable being developed by engineers at Sandia National Laboratories.

It’s common to isolate communications between systems or devices by using fiber optic cables, said Steve Sanderson of Sandia’s mobility analysis and technical assessment division. But when power also is required, sending it down a copper wire can at times be a safety issue, and substituting it with battery power may not be suitable or practical, he said.

Sanderson, Titus Appel and Walter Wrye, a former Sandia intern, are co-inventors of a hybrid cable design that uses fiber to send and regulate optical power to the communications electronics integral to the cable. A patent is pending on the design.

When Steve Jobs unveiled the iPhone in 2007, no one understood at the time how disruptive that device would be to existing technology. Now with rumors of Apple launching their augmented reality (AR) smart glasses products next year, people are speculating about how disruptive this technology will be.

Since iPhones are one of Apple’s primary revenue streams, they may be cautious about releasing a product that may encroach on their own turf. However, as we’ll suggest below, it may not be an either/or situation for users.

Using the Large Phased Array (LPA) radio telescope of Pushchino Radio Astronomy Observatory (PRAO) in Russia, astronomers have detected seven new pulsars and determined their basic parameters. The finding is reported in a paper published August 18 on the arXiv pre-print repository.

Pulsars are highly magnetized, rotating emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission; however, some of them are also observed via optical, X-ray and gamma-ray telescopes.

Now, a group of Russian astronomers led by PRAO’s Sergey Tyul’bashev reports the detection of seven new pulsars. The discovery was made with LPA as part of a daily sky survey conducted in a test mode, covering a full day in right ascension and 50 degrees in declination. The new pulsars were detected at a frequency of 111 MHz.

TOKYO (AP) — A small robot with a clip-like hand and enough smarts to know which drinks are popular is part of an effort to make convenience stores even more convenient.

On a recent day in Tokyo, the robot named TX SCARA slid back and forth behind the refrigerated shelves in the back of a FamilyMart store.

The hand on the end of its mechanical arm grasped a bottle or can from the stacks to the side, then the robot slithered to the right spot and placed the drink on the shelf — in a place chosen after its artificial intelligence and tiny cameras matched the kind of beverage to what’s running short.
