Every minute, on average, at least one person dies in a crash. If you read this article from start to finish, 30 or more deaths will have occurred across the globe by the time you are done. Auto accidents will also injure at least 10 million people this year, two or three million of them […]

In the Beginning: Gordon Teal (far left) directed the development of the silicon transistor at Texas Instruments. William Shockley (second from left) led the team at Bell Telephone Laboratories that developed the very first transistor, which was made of germanium. TI’s silicon device (second from right) with its three long leads became famous, making the

Illustration: Harry Campbell We do love our cellphones. And we hate them, too, of course—when they drop a call, go dead in the middle of a conversation, or simply fail to work in another country. Soon we’ll probably be complaining about other things—perhaps that our handsets can’t receive satellite TV broadcasts or last more than

Despite many investors’ predictions of a market sell-off triggered by the resurgence of COVID-19 cases and high inflation, the demand for advanced technologies is expected to remain high in the digital era. So, irrespective of the market’s near-term reaction to recent developments, we think it is wise to bet on quality tech stocks STMicroelectronics (STM),

Illustration: Mark Montgomery The problem has bedeviled designers for decades: How do you squeeze more and more antennas into smaller and smaller mobile devices? It’s tempting to think that the answer is simply to use smaller antennas or to pack them closer together, but there are fundamental constraints on antenna size and placement. Antennas emit

As people and businesses grow more reliant on technology, tech companies are widening their bases and expanding their offerings to capitalize on the growing demand. Furthermore, with widespread digitalization across nearly every industry, and the increasing deployment of the 5G networks, investors are becoming evermore bullish about the industry. This is evidenced by the iShares

You can do it all with terahertz technology—or so you might believe after perusing popular accounts of the subject. The truth is a bit more nuanced.

SPECIAL REPORT: DO-IT-ALL DEVICESLike the idea of a handheld device that can be any of about 10 different gizmos, depending on your mood? You could soon have one if the ideas described in this two-part report become reality. In this article, Nick Tredennick and Brion Shimamoto of the Gilder Technology Report tell why only programmable logic devices

IMAGE: JAMES LUKENS, STATE UNIVERSITY OF NEW YORK AT STONY BROOK [1] Researchers have demonstrated simple digital frequency dividers with Josephson junctions that have 0.25-µm minimum features and that operate at data rates up to 770 Gb/s. They rely on rapid single flux quantum (RSFQ) circuits, whose speed grows as junction sizes shrink. At 0.25

The year is 2028. It’s 8 p.m. on a Wednesday night and you’re famished. You’re staring wistfully at the only remaining item in your refrigerator: a package of sausages with an unappetizing grayish hue. Ugh. Did they always look like that? Are they still safe to eat? In 2018, you’d have to rely on your
