Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation.Gizmodo’s Top Five Gadgets of 2023The equation at work here is Einstein’s E = mc^2, which establishes a relationship between energy and mass; specifically, the equation holds that energy and mass are equivalent when the latter is multiplied by the speed of light, squared. A team led by scientists at Osaka University and UC San Diego recently simulated…

A team of physicists determined that enigmatic ‘antinuclei’ can travel across the universe without being absorbed by the interstellar medium. The finding suggests we may be able to identify antimatter that is produced by dark matter in deep space.The physicists estimated the Milky Way’s so-called transparency to antihelium-3 nuclei—meaning, how permissive the galaxy’s interstellar medium is to antinuclei zipping through space.“Our results show, for the first time on the basis of a direct absorption measurement, that…

… and they actually look fun enough that I’ve got a half a mind to enroll in my local police academy, if it comes with a standard-issue patrol trike. The Trikke Positron, which is the trike’s official name, is an all-wheel-drive standing electric scooter that very well could have criminals scratching their heads, at least if they weren’t already cuffed behind their backs. The idea that Trikke is trying to sell is that these are apparently the ultimate patrol vehicles for a beat cop. According to the company, a…
