In a series of recent tests in New Mexico, the Persistent Optical Wireless Energy Relay (POWER) program achieved several new records for transmitting power over distance. The team recorded more than 800 watts of power delivered during a 30-second transmission from a laser 8.6 kilometers (5.3 miles) away. Over the course of the test campaign, more than a megajoule of energy was transferred. Previously, the greatest reported distance records for an appreciable amount of optical power (>1 microwat

Thanks to war, geopolitics, and climate change, Europe will have more frequent and more severe internet disruptions in the very near future. Governments and businesses need to prepare for catastrophic loss of communications. Unfortunately, the necessary changes are risky and expensive, which means they won’t do it until a crisis is already here. However, small groups of volunteers with a little bit of time and money can provide crucial initial leadership to bootstrap recovery. An Internet Resil

Nintendo is a lot of things to a lot of people for a lot of different reasons. Mario helps, and so do the host of other iconic first-party titles and the movies, toys, theme parks, and endless other IP offshoots they spawned. But beyond how Nintendo looks and plays and sells, it also has a sound, and thanks to the Switch 2, that sound is just as iconic as ever this time around.

How to set up a WhatsApp account without Facebook or Instagram

engadget.com Unknown 2026-03-19 22:00:24

There's no shortage of reasons to stay off the Meta ecosystem, which includes Facebook and Instagram, but there are some places where WhatsApp remains the main form of text-based communication. The app is a great alternative to SMS, since it offers end-to-end encryption and was one of the go-to methods to send uncompressed photos and videos between iPhone and Android users before Apple adopted RCS. Even though Facebook, which later rebranded to Meta, acquired WhatsApp in 2014, it doesn't require

The Skyscraper That Could Have Toppled over in the Wind (1995)

Within this seemingly simple computation, however, lurks a powerful multiplier. At any given level of the building, the compression figure remains constant; the wind may blow harder, but the structure doesn’t get any heavier. Thus, immense leverage can result from higher wind forces. In the Citicorp tower, the forty-per-cent increase in tension produced by a quartering wind became a hundred-and-sixty-per-cent increase on the building’s bolts. Precisely because of that leverage, a margin of safe

David Attenborough at 99: 'I will not see how the story ends'

news.ycombinator.com David Attenborough 2026-03-19 22:21:28

My earliest memory of the ocean is of a tropical lagoon. Ammonites rose and fell in the warm water column, occasionally propelling themselves forwards, their curled ram’s horn shells surprisingly streamlined in the water. This tropical lagoon was in fact in my imagination, fired as I explored the old limestone quarry near my childhood home in Leicester, some 60 miles from the coast. For a small boy in the 1930s this was a marvellous place for adventures, and the knowledge that millions of year

Taiwan places export controls on Huawei and SMIC

Scientists Discover Bizarre Signals Coming From Ice in Antarctica

Some strange radio signals are broadcasting out of Antarctic ice, and the researchers who found them don't know why.
