The PowerRay underwater drone finds fish and films them in 4K

If you’re heading out to the coast or the lake for a spot of fishing, you can have the best gear and the perfect bait but you won’t land anything if you’re set up in the wrong spot. Experience can only guide so you so much, so PowerVision — the company behind the incredible PowerEgg drone we saw last year — has built an underwater robot called the PowerRay to help find and lure in your next catch. The PowerRay can dive down to 30 meters (98 feet) underwater, where it can use an optional “Fishfinder” sonar component to detect fish another 40 meters below it. The drone’s WiFi system beams video and images captured by its integrated 4K camera and additional data on the underwater landscape and temperature up to the surface, which can then be viewed via the dedicated iOS or Android app. It also features an “internal fish luring light” that will apparently attract fish with a welcoming “hue of blue” and an optional remote-controlled bait drop that can place tasty snares in your desired location. If that’s not immersive enough, PowerVision wants to add a touch of virtual reality to proceedings. The PowerRay comes with an option to be controlled by a wearable device or via its own VR goggles. The PowerVision VR Goggles recognize both “gravity and gestures, ” allowing you to control the robot by simply moving your head. If you’re looking to be the envy of all your fishermen and women friends, the PowerRay will be available for pre-order from February 27th. PowerVision hasn’t yet announced a price, but judging from the company’s other robots, expect it to be on the high side. Click here to catch up on the latest news from CES 2017.

Sea anemones could be the key to treating hearing loss

Sea anemones could soon do a lot to help those of us living above the water. Researchers have discovered that proteins used by starlet sea anemones to repair their cells also repair the sound-sensing cells in mice and other mammals. If you bathe cells in those proteins for long enough (the team tried for an hour), they rapidly restore molecular links that bundle hearing-related hair cells together. In theory, you could reverse hearing damage among cells that haven’t been permanently lost — that exceptionally loud concert might not permanently limit your listening enjoyment. There’s a lot of work to be done before there’s an actual treatment. However, scientists don’t think you’d always need anemone cells to make this work. At least in mice, there are repair proteins that parallel those from the underwater creatures. If researchers can find a way to improve their effectiveness (mammal proteins are much less useful right now), you wouldn’t need to harvest them from sealife to deliver effective treatments.

This Diver Is Cradling a 12,000-Year-Old Skull in an Underwater Cave

Inside a cave so deep and dark it’s called Hoyo Negro, or Spanish for “black hole, ” divers are transporting a 12, 000-year-old skull for 3D scanning. The skull belongs to one of the oldest and most complete skeletons ever found in the Americas. Lucky for us, the expedition was documented with an entire set of stunning photos. Read more…
