MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight can, powering laptops, cell phones, radios and other electronic devices.
It could also dramatically lighten the load for people who can’t connect to a power grid, including soldiers who now must carry many pounds of batteries for a three-day mission — all at a reasonable price.
The researchers say that in the long term, mass-production could bring the per-unit cost of power from close to that for power from today’s large gas-turbine power plants.
A new interpretation of quantum mechanics sees agents as playing an active role in the creation of reality. Blake Stacey outlines the case for QBism and its radical potential.
The pandemic shut down our university when I was in the middle of giving a lecture. We had been anticipating the possibility for a few days, but it was still impeccable timing. I finished my spiel, out came the phones, and suddenly we weren’t going to see each other post-spring break after all. For the rest of the term, I did what so many teachers found themselves doing: gamely trying to soldier on. I scrounged and borrowed a whiteboard, easel and webcam, set myself up in the nicest light the house had to offer, and did my best to convey graduate-level physics to an audience of tiny rectangles. And like so many other teachers, I learned there’s nothing like a radical change of circumstances for driving one to re-evaluate what the essential ideas of a subject must be.
Apple and Tesla have a lot in common, but there’s much to be desired — oddly enough — when it comes to how their products work together.
Apple Inc. and Tesla Inc. have a lot in common, but there’s much to be desired — oddly enough — when it comes to how their products work together.
Both companies are known for design, advanced technology and a controlling approach to their ecosystems. Tesla’s cars use a giant iPad-like screen instead of physical controls, and customers can use a smartphone as their key. It’s also steadily moving toward autonomous driving. That’s led people to call Tesla the Apple of carmakers. Elon Musk even tried to sell Tesla to Apple, and consumers frequently say that a Tesla is an “iPhone on wheels.”
But for Apple users, the experience of owning a Tesla can be frustrating.

Today, wireless charging is little more than a gimmick for high-end smartphones or pricey electric toothbrushes. But a new approach that can charge devices anywhere in a room could one day allow untethered factories where machinery is powered without cables. As the number of gadgets we use has steadily grown, so too has the number of cables and chargers cluttering up our living spaces. This has spurred growing interest in wireless charging systems, but the distances they work over are very short, and they still have to be plugged into an outlet. So, ultimately, they make little difference.
This is only a prototype though, and considering the dramatic increase in efficiency between the first and second versions, this efficiency gap could be closed. A more pressing concern might be the cost and complexity of retrofitting buildings with massive aluminum plates in the walls.
Indeed, the researchers are working on both issues. “We’ve just developed a brand-new technique. Now we have to go figure out how to make it practical,” Sample told Scientific American.
Still, while this kind of seamless wireless charging won’t be ubiquitous in the near term, the technique could soon be used in niche situations, like charging cabinets for power tools, and ultimately, the researchers think it could be make the factories of the future cable-free.
Earlier this year, researchers found a deposit of rare-earth minerals off the coast of Japan that could supply the world for centuries, according to a study.
The study, published in the journal Nature in April 2,018 says the deposit contains 16 million tons of the valuable metals.
Rare-earth minerals are used in everything from smartphone batteries to electric vehicles. By definition, these minerals contain one or more of 17 metallic rare-earth elements (for those familiar with the periodic table, those are on the second row from the bottom).
These elements are actually plentiful in layers of the Earth’s crust, but are typically widely dispersed. Because of that, it is rare to find any substantial amount of the elements clumped together as extractable minerals, according to the USGS.
Arizona, and Georgia will introduce the system first, with Connecticut, Iowa, Kentucky, Maryland, Oklahoma, and Utah also signed up.
The “first locations” to use the system will be airport security checkpoints run by the Transportation Security Administration (TSA), Apple says.
Americans usually need some form of state ID only to travel by air domestically, unlike other countries, in which a passport is widely used.
Tapping a phone at an identity reader at supported airports will prompt passengers to use their Face ID or fingerprint to authorise sending information to the machine.
“Users do not need to unlock, show, or hand over their device to present their ID,” Apple said.
Apple’s new ID system for its Wallet will be rolled out at airports to start.
Eight states will roll out a feature allowing users to add driver’s license and state IDs to Apple Wallet for iPhone and Apple Watch to use at security at participating airports, Apple announced Wednesday.
Arizona and Georgia are the first states to adopt the feature and Connecticut, Iowa, Kentucky, Maryland, Oklahoma and Utah will follow, though the company did not specify a timeline.
As the use of facial recognition technology (FRT) continues to expand, Congress, academics, and advocacy organizations have all highlighted the importance of developing a comprehensive understanding of how it is used by federal agencies.
The Government Accountability Office (GAO) has surveyed 24 federal agencies about their use of FRT. The performance audit ran from April2020through August 2021. 16 of the 24 agencies reported using it for digital access or cybersecurity, such as allowing employees to unlock agency smartphones with it, six agencies reported using it to generate leads in criminal investigations, five reported using FRT for physical security, such as controlling access to a building or facility, and 10 agencies said they planned to expand its use through fiscal year 2023.
In addition, both the Department of Homeland Security (DHS) and the Department of State reported using FRT to identify or verify travelers within or seeking admission to the United States, identifying or verifying the identity of non-U.S. citizens already in the United States, and to research agency information about non-U.S. citizens seeking admission to the United States. For example, DHS’s U.S. Customs and Border Protection used its Traveler Verification Service at ports of entry to assist with verifying travelers’ identities. The Traveler Verification Service uses FRT to compare a photo taken of the traveler at a port of entry with existing photos in DHS holdings, which include photographs from U.S. passports, U.S. visas, and other travel documents, as well as photographs from previous DHS encounters.
The iPhone 13 will feature low earth orbit (LEO) satellite communication connectivity to allow users to make calls and send messages in areas without 4G or 5G coverage, according to the reliable analyst Ming-Chi Kuo. In a note to investors, seen by MacRumors, Kuo explained that the iPhone 13 lineup will feature hardware that is able to connect to LEO satellites. If enabled with the relevant software features, this could allow iPhone 13 users to make calls and send messages without the need for a 4G or 5G cellular connection.
