These Chunks of Ice Move All By Themselves, Thanks to a Cool Engineering Trick

gizmodo.com Margherita Bassi 2025-11-18 06:20:54

It looks like something straight out of a Ouija board horror movie, but frosty—researchers have figured out how to make ice move by itself. A video capturing the creepy dynamic features an ice disk melting on a metal surface etched with an asymmetrical herringbone pattern. The ice and its small puddle slowly start to move sideways before suddenly picking up speed and slingshotting across the metal plate. The researchers suggest that this sort of independent movement could one day generate power

Samsung phones could finally offer a vivid photo profile, but there’s bad news

Ryan Haines / Android Authority TL;DR A leaker claims Samsung could offer a ‘vivid’ photo style in ‘the next version’ of One UI 8.

Deep-Sea Desalination Pulls Fresh Water from the Depths

From Cape Town to Tehran to Lima to Phoenix, dozens of cities across the globe have experienced water shortages recently. And in the next five years the world’s demand for fresh water could significantly outpace supply, according to a United Nations forecast. Now several companies are turning to an unexpected source for a solution: the bottom of the ocean. Called subsea desalination, the idea is to remove the salt from water in the deep sea.
