The Download: a promising retina implant, and how climate change affects flowers

A competitor to Neuralink has developed a promising retina implant that allows people with vision loss to read text and do crosswords. The implant, placed under the retina, uses signals from a camera to emit bursts of electricity, bypassing damaged photoreceptor cells. In another story, a new artistic project explores how flowers may change in response to climate change, with factors like petal pigmentation and size being influenced by climate conditions. Additionally, Redwood Materials is repurposing old electric-vehicle batteries for AI microgrids to power data centers.
