When Doug Wheelock came home from the International Space Station in November 2010, the first thing that startled him was not a meal, a shower, or a bed. It was the smell of Earth. ABC News later asked Wheelock about returning from orbit, and he described the thing he had missed in the plainest possible terms: “I craved the aroma of leaves and grass and flowers and trees.” He called it “Earthiness.” That matters because Wheelock’s long station flight had not lasted 178 days, as the common shorthand sometimes implies. NASA’s own mission record says Expedition 24/25 kept him in…
US lawmakers urge tighter rules on contract chipmakers supplying Chinese firms’ overseas units
Critics say that setting up orbital data centers is easier said than done. But Musk argues that it’s not a “super hard problem” to solve.
Grace Hopper kept a bundle of wires, each one cut to exactly 11.8 inches. She handed them out at lectures, in Navy briefings, and to anyone who asked why the new satellite links felt sluggish. The wire, she explained, was a nanosecond. That was how far light could travel in one billionth of a second, and no amount of engineering or budget would ever shrink it. She called them her “nanoseconds.” By the end of her career she had given them out at hundreds of talks across the country. The bit became one of the most famous demonstrations in computing…
Most investors who pile into the S&P 500 in 2026 think they own the entire stock market. What they actually own is nothing more than a heavy bet on Big Tech — and right now, that bet has run its course.
High-yield savings account rates have held steady, with some banks even increasing their rates, to start June.As of June 8, 2026, some online banks are still offering interest rates up to 5.00% APY, but these top APYs are usually limited by deposit size. This is still much better than the average of 0.38% APY, according to the FDIC.Banks and credit unions are constantly adjusting their annual percentage yields (APYs) as markets react to Federal Reserve policy and inflation data, so staying up to date can make a real difference. Here’s where the best savings rates stand today — and what…
In 1965, Mary Allen Wilkes was writing software in her parents’ Baltimore home for a computer that weighed about 250 pounds and sat in the living room like a piece of laboratory equipment that had wandered into the wrong century. The machine was the LINC, short for Laboratory Instrument Computer. It had a small display, a keyboard, magnetic tape drives, toggle switches, and enough memory to make a modern smartwatch look like a supercomputer. Wilkes was finishing LAP6, the interactive operating system that made the LINC usable by scientists who were not computer specialists. She was also doing something that…
There’s a version of physician productivity advice that sounds like this: wake up earlier, batch your tasks, use the Pomodoro technique. And there’s nothing wrong with any of it. But it’s all still you doing the work. The more useful question is: which of these tasks didn’t need you in the first place? For most physicians building income outside of medicine, the answer is more than they realize. And the most cost-effective way to address that gap is also one of the least utilized: a virtual assistant. Not a full-time hire. Not a complex system. A part-time VA, starting with…
International graduate enrollment at U.S. colleges fell again this year, and the financial damage is showing up fast in layoffs, budget deficits, and shuttered degree programs. For years, foreign graduate students were a quiet engine of university finances: paying full tuition, staffing research labs, and filling master’s programs that schools built out to grow revenue. Now that engine is stalling. Tighter visa policies, thousands of revoked visas, and growing uncertainty about studying in the U.S. have cut into the pipeline, and the institutions that bet most heavily on international enrollment are the ones now scrambling to close the gap. Would you…
