Scientists discover lithium replacement that may revolutionize EV batteries: ‘99.7% efficient after over 400 hours of use’

Scientists discover lithium replacement that may revolutionize EV batteries: ‘99.7% efficient after over 400 hours of use’ Story by Ben Stern • 14h ago Maryland is already famous for its crabs — but researchers at the University of Maryland are looking to give that distinction an entirely different meaning. A team of scientists at the school’s Center for Materials Innovation found that crustaceans like crabs and lobsters contain a chemical in their shells called chitin, which can be used to power batteries when combined with zinc. Crustacean shells packed with this chemical are typically thrown out en masse by restaurants that have no other use for them. But researchers believe this waste could serve as a powerful resource in the search for more sustainable batteries. Lithium-ion batteries, the common kind found in most of our cellphones and laptops, can take hundreds of thousands of years to break down after they’re used up — not to mention the devastating environmental impact lithium extraction has on our planet. But these shellfish batteries are biodegradable and can decompose in soil after just five months, leaving behind zinc, which can be recycled. The University of Maryland’s study also found that chitin-zinc batteries were 99.7% efficient after over 400 hours of use, as reported by The Guardian, and that these batteries could likely be produced cheaply at scale. As the world transitions away from dirty energy sources, like methane gas and coal, it’ll need tons of cheap and environmentally friendly batteries. Crustaceans could provide a solution, especially in hopes of lessening our reliance on lithium-ion batteries. Speaking with The Guardian, Graham Newton, a professor of materials chemistry at the University of Nottingham who studies sustainable battery technology, was cautiously optimistic about the discovery. “When you develop new materials for battery technologies there tends to be a significant gap between promising lab results and a demonstrable and scalable technology,” Newton, who is not affiliated with the Maryland study, told the outlet. https://www.msn.com/en-us/money/technology/scientists-discover-lithium-replacement-that-may-revolutionize-ev-batteries-99-7-efficient-after-over-400-hours-of-use/ar-AA12LkSa

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that the patient is 3,000 kilometers away,”  he said.

Visualizing The Power Of The World's Supercomputers

Visualizing The Power Of The World's Supercomputers   BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM   A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is  flops , or  floating point operations per second . In this visualization,  Visual Capitalist's Marcus Lu uses  November 2021 data from  TOP500  to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used  teraflops  as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku  was completed in March 202

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke
