Should You Leave Your Phone Charging Overnight? It used to be common wisdom that leaving your phone charging overnight degrades the battery. But handset design has evolved to mitigate the harm caused by constant charging. You may have heard that leaving your smartphone charging overnight--either plugged in or atop a wireless charger --can damage your battery. But is it actually harmful or dangerous to do that?

Datasets of complex cyber-physical systems (CPS) are difficult to build and large CPS datasets are not publicly available.

Technology Engineering Thomas Edison's failed rechargeable battery may get a second life The famed inventor's nickel-iron idea isn't suited for EVs, but it could help solar farms and data centers. Breakthroughs, discoveries, and DIY tips sent six days a week. A rechargeable battery based on technology pioneered by Thomas Edison may finally get its due. But while the famous inventor envisioned nickel-iron batteries powering the automobile industry over a century ago, researchers now believe the underlying concepts are more suited for renewable energy centers. According to a study published in the journal, a team including engineers from the University of California, Los Angeles have developed a prototype battery that recharges in seconds and withstands over 12,000 cycles of use--an equivalent to over 30 years of daily activity.

Chinese firms are building battery plants from Europe to North America, promising jobs while prompting local concerns about the environment, politics, and who really benefits. When the rest of WIRED subscribers get their hands on our next print magazine, you, dear readers of Made in China, can proudly say you heard about it here first. The issue is all about China and includes stories about robots, AI boyfriends, a Chinese town that became the crystal capital of the world, and a Chinese DNA database built for family reunions. Like this newsletter, the issue is our attempt to document how deeply Chinese technology now shapes everyday life--no matter where you live in the world. As part of the issue, I reported a story on how Chinese lithium battery companies like CATL, BYD, and Gotion are now building factories on nearly every continent.

You'd never guess this lock is smart by looking at it, and that's my favorite part. No bulk or screen; looks like a regular lock from both sides of the door. Impressive design with the battery hidden inside the lock bolt. App is beautiful and easy to use. Best with accessories that need to be purchased separately.

China's lithium batteries aren't always "made in China." Companies like BYD and CATL are building factories on nearly every continent. THE symbolism was clear last June when Emmanuel Macron, surrounded by factory workers, held up a sleek lithium battery in his right hand and a mining lamp in his left. He was in Douai, a northern French city with a coal mining history dating back to the 1700s. The city is now also the site of a battery factory, which would allow France to produce all parts of electric vehicles domestically. This factory, Macron declared, represented an "economic and ecological revolution."

Plus: This company is developing gene therapies for muscle growth, erectile dysfunction, and "radical longevity" For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium's limited supply and volatile price have led the industry to seek more resilient alternatives. They work much like lithium-ion ones: they store and release energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element that is currently mined in only a handful of countries, sodium is cheap and found everywhere. Read why it's poised to become more important to our energy future. Sodium-ion batteries are one of 10 Breakthrough Technologies this year.

These rare sea creatures live where the sun don't shine. Breakthroughs, discoveries, and DIY tips sent every weekday. Like a scene out of a Jules Verne novel, scientists from Schmidt Ocean Institute recently encountered a giant phantom jelly (). The enormous deep-sea jellyfish was spotted about 830 feet below the surface of the Pacific Ocean by a Remotely Operated Vehicle (ROV) exploring the Colorado-Rawson submarine canyon wall off the coast of Argentina. ROV pilots filmed this giant phantom jelly, or Stygiomedusa gigantea, at 253 meters during an ROV descent to explore the Colorado-Rawson submarine canyon wall.
