These magnificent rays are at risk of disappearing due to targeted fishing, being caught as bycatch, and climate change. Scientists at the research collaboration Mobula Conservation are teaming up with artisanal and industrial fishermen to protect them. Also known as "Devil Rays," mobulas are elasmobranchs: a subclass of fish--including sharks, skates, and sawfish--that are distinguished by having skeletons primarily made from cartilage. More than a third of the species in this group are threatened with extinction. Of the nine species of mobulas, seven are endangered and two are vulnerable according to the International Union for Conservation of Nature.

Apple's long-awaited mixed-reality headset, the Vision Pro, is here. Or not yet here, but announced. In a crescendoed moment of its software conference keynote this morning, Apple executives revealed a pair of smart goggles that portend a post-iPhone world. I had a hands on (heads on?) demo of the Vision Pro headset earlier today, in a building constructed on Apple's campus specifically to house meetings around this new product. Apple executives declined to go on the record during the demo and subsequent briefing, but it was clear that Apple views Vision Pro as a spatial computing platform, not a singular device.
