Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal Scientific Reports. Per the authors, it's the first example of a biolaser cavity within the animal kingdom. As previously reported, the bright iridescent colors in things like peacock feathers and butterfly wings don't come from any pigment molecules but from how they are structured. The scales of chitin

Studies Show AI Models Love to Share With One Another (and Do a Little Price Fixing as a Treat)

gizmodo.com Aj Dellinger 2025-12-23 09:10:01

Sharing is caring. Two recent studies took a look at what happens when you let AI models communicate with each other. Both should probably give us pause about letting these machines make friends with one another. The first study—a preprint paper out of Northeastern University’s National Deep Inference Fabric, which seeks to peer into the black box of large language models and understand how they work—found that AI models pass along hidden signals to one another during training.

Hexatetrahedral Rails

news.ycombinator.com Unknown 2025-12-19 23:56:32

Software is a creative endeavor and a craft. And like any creative endeavor and any craft, it is subject to fashions. About a decade ago, one of those fashions was Hexagonal Rails largely inspired by the DDD book, but also by the original Hexagonal Architecture work by Dr. Cockburn. Some of these applications are now up for their Rails upgrade and an “oil change,” and it’s interesting to see them in the wild and how they get perceived through the lens of the years that have gone by since then.
