Have We Been Thinking About Exercise Wrong for Half a Century?

"After a half-century asking us to exercise more, doctors and physiologists say we have been thinking about it wrong," writes Washington Post columnist Michael J. Coren. "U.S. and World Health Organization guidelines no longer specify a minimum duration of moderate or vigorous aerobic activity." Movement-tracking studies show even tiny, regular bursts of effort - as short as 30 seconds - can capture many of the health benefits of the gym. Climbing two to three flights of stairs a few times per day could change your life. Experts call it VILPA, or vigorous intermittent lifestyle physical activity. "The message now is that all activity counts," said Martin Gibala, a professor and former chair of the kinesiology department at McMaster University in Canada... Just taking the stairs daily is associated with lower body weight and cutting the risk of stroke and heart disease - the leading (and largely preventable) cause of death globally. While it may not burn many calories (most exercise doesn't), it does appear to extend your health span. Leg power - a measure of explosive muscle strength - was a stronger predictor of brain aging than any lifestyle factors measured in a 2015 study in the journal Gerontology... How little activity can you do? Four minutes daily. Essentially, a few flights of stairs at a vigorous pace. That's the effort [Emmanuel Stamatakis, a professor of physical activity and population health at the University of Sydney] found delivered significant health benefits in that 2022 study of British non-exercisers. "We saw benefits from the first minute," Stamatakis said. For Americans, the effect is even more dramatic: a 44 percent drop in deaths, according to a peer-reviewed paper recently accepted for publication. "We showed for the first time that vigorous intensity, even if it's done as part of the day-to-day routine, not in a planned and structured manner, works miracles," Stamatakis said. "The key principle here is start with one, two minutes a day. The focus should be on making sure that it's something that you can incorporate into your daily routine. Then you can start thinking about increasing the dose." Intensity is the most important factor. You won't break a sweat in a brief burst, but you do need to feel it. A highly conditioned athlete might need to sprint to reach vigorous territory. But many people need only to take the stairs. Use your breathing as a guide, Stamatakis said: If you can sing, it's light intensity. If you can speak but not sing, you're entering moderate exertion. If you can't hold a conversation, it's vigorous. The biggest benefits come from moderate to vigorous movement. One minute of incidental vigorous activity prevents premature deaths, heart attacks or strokes as well as about three minutes of moderate activity or 35 to 49 minutes of light activity.

Are Big Tech's Nuclear Construction Deals a Tipping Point for Small Modular Reactors?

Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects - enough to power almost 3 million homes - for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals - not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions." Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

A New Era for Security? Anthropic's Claude Opus 4.6 Found 500 High-Severity Vulnerabilities

Axios reports: Anthropic's latest AI model has found more than 500 previously unknown high-severity security flaws in open-source libraries with little to no prompting, the company shared first with Axios. Why it matters: The advancement signals an inflection point for how AI tools can help cyber defenders, even as AI is also making attacks more dangerous... Anthropic debuted Claude Opus 4.6, the latest version of its largest AI model, on Thursday. Before its debut, Anthropic's frontier red team tested Opus 4.6 in a sandboxed environment [including access to vulnerability analysis tools] to see how well it could find bugs in open-source code... Claude found more than 500 previously unknown zero-day vulnerabilities in open-source code using just its "out-of-the-box" capabilities, and each one was validated by either a member of Anthropic's team or an outside security researcher... According to a blog post, Claude uncovered a flaw in GhostScript, a popular utility that helps process PDF and PostScript files, that could cause it to crash. Claude also found buffer overflow flaws in OpenSC, a utility that processes smart card data, and CGIF, a tool that processes GIF files. Logan Graham, head of Anthropic's frontier red team, told Axios they're considering new AI-powered tools to hunt vulnerabilities. "The models are extremely good at this, and we expect them to get much better still... I wouldn't be surprised if this was one of - or the main way - in which open-source software moving forward was secured."
