A newly discovered way to monitor magma movements beneath Mount Etna could help scientists forecast when it might erupt.Mount Etna, located on the Italian island of Sicily, is Europe’s largest active volcano. Humans have documented its activity for the past 2,700 years, but the volcano’s eruptive history stretches as far back as 500,000 years.Etna’s most recent eruption, in June 2025, ejected a giant, 4-mile-high (6.5 kilometers) cloud of ash and triggered an avalanche of hot lava blocks and other debris. The eruption was expected, so officials were able to issue warnings on the morning of the event, but predictions don’t…

It’s hard to remember now that people used to be skeptical about electric bikes. Cyclists didn’t want unlicensed motor vehicles in bike lanes; people who didn’t bike found them to be dangerous. Even as more people adopt them to deal with carbon emissions or traffic, ebikes still have many issues. Cheap ones are impossible to repair. The nice ones have gut-punch prices, especially if this is your second or third vehicle. They have a learning curve when it comes to riding.I’ve been reviewing electric bikes for years and, as many reviewers do, tend to evaluate them as an assemblage of…

A lab accident has led engineers to build a chip that fires a rainbow of powerful laser beams — and it could help data centers better manage skyrocketing volumes of artificial intelligence (AI) data.The new photonics chip contains an industrial-grade laser source paired with a precisely engineered optical circuit that shapes and stabilizes the light before splitting it into multiple, evenly spaced colors.Because each color band represents an optical frequency that can carry its own unique stream of data, the technology could enable data centers to move information around far faster and more efficiently than existing optical networks such as…

On the night of April 19, 1787, astronomer William Herschel noted an hours-long light as bright as the Orion Nebula emanating from the unlit, new moon. He had likely witnessed a “transient lunar phenomenon” (TLP) — a short-term change in the appearance of part of the lunar surface.TLPs include brightening, reddish or violet blotches and foggy spots. In fact, some 3,000 TLPs have been documented over the past two millennia by people wielding telescopes, cameras or just plain good vision, said Anthony Cook, a research lecturer in physics at Aberystwyth University in the U.K.But what causes these strange flashes on…

Everything stored in your Keeper vault is known as a record. There are several different record types, including logins, credit cards, identities, secure notes, and software licenses, but you can also create a general record with any fields you want, as well as add custom fields and attach files to other record types. Rather than tags or categories, Keeper lets you make folders, and you nest folders within each other.You can share at a record or folder level. Record sharing speaks for itself, but folder sharing is interesting. Rather than sharing a full vault, as you have to do with…

Missed Prime Day? Not to worry. The main event may have come to an end, but you can still save big on fitness gear and exercise equipment, and not just at Amazon, but also at Best Buy, Walmart and other major retailers. We have spotted some truly massive late-minute deals on treadmills, rowing machines, fitness trackers and running headphones, so snatch them up while they are still live.You can trust us here — we have tried and tested most of the fitness products listed here, and we are keeping an eye on price drops to bring you only the biggest…

Decreased suction power can be harder to notice if you aren’t looking carefully. I certainly hadn’t realized how weak my old vacuum had become until I started using a new one. Frequent clogs might be a sign of age, but they can also be a sign that you need to do a better job cleaning your vacuum and making sure the tubes are clear before you start your next cleaning session.Courtesy of Bissell; NarwalA Vacuum’s LifetimeSo, how long does a vacuum last? Eufy, which makes vacuums and other smart home goods, says a vacuum lasts on average between five and…

QUICK FACTSName: Roos Carr figuresWhat it is: A set of figurines carved from yew wood and quartziteWhere it is from: Roos Carr, East Yorkshire, U.K.When it was made: Circa 600 to 500 B.C.This set of carved figurines was discovered in the parish of Roos, on England’s east coast. The carvings, which have been carbon-dated to the Late Bronze Age, may have been offered to the god Odin.When laborers were digging a drainage ditch in 1836, they discovered a set of eight human figures, two miniature boats and an assortment of arms and tiny weapons underneath a layer of blue clay.…

This is arguably personal taste. Certainly if you’re looking to stop eyeballs mid-scroll with oversaturated, eye-popping color, the Insta360 X5 is your friend. Personally though, I like the color coming from the GoPro much better, even when shooting in 8-bit color. It’s probably worth checking out some video from both to see which look you prefer before you invest. One advantage of the GoPro is that if you do want to get into postproduction coloring in apps like DaVinci Resolve, the 10-bit color option gives you a lot more latitude.I also found that, in bright light, shooting the sort of…
