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

Plus: AWS is working to get its customers' services back online following a major outage Science Corporation--a competitor to Neuralink founded by the former president of Elon Musk's brain-interface venture--has leapfrogged its rival after acquiring a vision implant in advanced testing for a fire-sale price. The implant produces a form of "artificial vision" that lets some patients read text and do crosswords, according to a report published in today. The implant is a microelectronic chip placed under the retina. Using signals from a camera mounted on a pair of glasses, the chip emits bursts of electricity in order to bypass photoreceptor cells damaged by macular degeneration, the leading cause of vision loss in the elderly. How will flowers respond to climate change? Flowers play a key role in most landscapes, from urban to rural areas.
