Generative AI model shows fake news has more impact when released at a steady pace without interruption
It's not at all clear that disinformation has, to date, swung an election that would otherwise have gone another way. But there is a strong sense that it has had a significant impact, nonetheless......»»
James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Study finds iron-rich enamel protects, but doesn"t color, rodents" orange-brown incisors
Chattering squirrels, charming coypus, and tail-slapping beavers—along with some other rodents—have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the.....»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
