Almost two decades after the U.S. Air Force started trying to replace the Vietnam-era helicopters that patrol missile fields and stand by to evacuate senior officials, the service announced Monday that it has placed an initial order of MH-139 helicopters with the team of Boeing and Italian defense firm Leonardo.
Nearly two out of three U.S. kids spend more than two hours a day looking at screens, a new analysis of activity levels finds. And those children perform worse on memory, language and thinking tests than kids who spend less time in front of a device, the study of over 4,500 8- to 11-year-olds shows.
The splurge by tech companies is behind an upswing in capital-goods spending among big U.S. companies, which is seeing its fastest growth in years, according to a Credit Suisse analysis. The $80 billion tab also is a snapshot of why it’s tough to unseat the tech giants. How can a company hope to compete with Google’s driverless cars when it spends $20 billion a year to ensure it has the best laser-guided sensors and computer chips?
U.S. tariffs that hit some $200 billion worth of Chinese products on Monday spare many high-profile consumer technology items such as “smart” watches and speakers, but the less flashy home modems, routers and internet gateways that make them work weren’t so lucky.
Quantum computing leverages principles from quantum mechanics (a branch of physics), notably the unique behaviors of subatomic particles such as electrons and photons, to enable new, extremely powerful computing architectures.
The T-Mobile-Sprint merger advances innovative wireless broadband services, offers significant benefits that will ultimately flow to consumers, and presents few competition concerns. It offers significant scale and operational efficiencies that will help accelerate the transition to next-generation 5G networks, intensify competition, and bring numerous benefits to the economy.
Almost nothing is known about the new bomber in development, the B-21 Raider, the most important Air Force project of the new century. But it will differ from previous bombers in one critical feature: rapid upgradability, according to Air Force Gen. Tim Ray, who leads the service’s Global Strike Command. In essence, there will be no single bomber but an ever-evolving platform that will change as technology and circumstances change as well.
The U.S. Navy needs a new warship to replace its aging force of cruisers, and it wants to start buying them in five years. Larger than a destroyer but smaller than a battleship, the ship will be stacked with sensors, weapons, and unmanned vehicles. The Navy believes the new ship--which will probably cost more than $2 billion each--is needed to retain the ability to protect America’s aircraft carriers and allies from attack.
This movement from discovery to implementation marks a significant shift in A.I.’s center of gravity -- away from the United States and toward China. The age of discovery relied heavily on innovation coming out of the United States, which excels at visionary research and moonshot projects. A.I. implementation, however, plays to a different set of strengths, many of which are manifested in China...
The transmission electron microscope was designed to break records. Using its beam of electrons, scientists have glimpsed many types of viruses for the first time. They’ve used it to study parts of biological cells like ribosomes and mitochondria. You can see individual atoms with it.
