At the 2017 Naval Future Force Science and Technology Expo in Washington DC, an ONR spokesman revealed that the weapon is ready for field demonstrations at the Naval Surface Warfare Center Dahlgren Division’s new railgun Rep-Rate Test Site at Terminal Range, according to New Atlas.

Initial rep-rate fires (repetition rate of fires) of multi-shot salvos already have been successfully conducted at low muzzle energy, officials say.

The next test sequence calls for safely increasing launch energy, firing rates and salvo size.

Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The paper was published online today in Nature.

The was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the in the hypothalamus that control aging: a tiny population of adult , which were known to be responsible for forming new brain neurons.

“Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging,” says senior author Dongsheng Cai, M.D., Ph.D., (professor of molecular pharmacology at Einstein. “But we also found that the effects of this loss are not irreversible. By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body.”

When you use smartphone AI apps like Siri, you’re dependent on the cloud for a lot of the processing — limited by your connection speed. But what if your smartphone could do more of the processing directly on your device — allowing for smarter, faster apps?

MIT scientists have taken a step in that direction with a new way to enable artificial-intelligence systems called convolutional neural networks (CNNs) to run locally on mobile devices. (CNN’s are used in areas such as autonomous driving, speech recognition, computer vision, and automatic translation.) Neural networks take up a lot of memory and consume a lot of power, so they usually run on servers in the cloud, which receive data from desktop or mobile devices and then send back their analyses.

Forget swiping a credit card or badge to buy food at work. One Wisconsin-based tech firm is offering to install rice-size microchips in its employees’ hands.

Three Square Market will be the fir st firm in the U.S. to use the device, which was approved by the FDA in 2004, CEO Todd Westby told CNBC on Monday.

“We think it’s the right thing to do for advancing innovation just like the driverless car basically did in recent months,” he said in an interview with “Closing Bell.”
