LED-lit fishing nets save sea turtles from getting caught
Sometimes, it's the simplest tech that makes the biggest difference. University of Exeter researchers have crafted fishing nets with evenly distributed green LED lights (one every 33 feet) that warn sea turtles away without spooking fish. While scientists have yet to nail the exact reason the lights steer the turtles clear, one researcher tells Tech Insider that it's likely just a matter of visibility -- the turtles stand a better chance of seeing the net in time to avoid it. It's not only quite effective in early tests (it reduced green turtle deaths by 64 percent), but relatively cheap at $100 to cover a giant 1,640ft net with 50 lights.
Tiny cameras spy on crows making tools
It's well-known that crows are smart enough to make tools. However, catching that crafting on video is sometimes a big challenge -- unless you lure the birds to a feeding site, you probably won't see the behavior. That's where the University of Exeter is coming to save the day. It recently developed cameras that are small and light enough to sit on crows and record their activity, letting scientists get the first footage of New Caledonian crows making foraging tools in the wild. The cams even have microSD cards and radio beacons to help recover footage when the devices slide off after a few days.
Diet-based 'video game' claims to make you thinner
We know that Pavlovian conditioning can make you do all sorts of crazy things, so could it be used to make us all a bit healthier? Psychologists from the universities of Exeter and Cardiff believe that it's possible after building a "computer game" that, essentially, trains you to steer clear of bad food. Unfortunately, the game itself is just a flashcard routine where players are asked to push a button when they're shown salad and hold off when they see cookies. If we're honest, the bad guys in the food and drink industry still have the upper hand, just look at Cool Spot, the 1993 platformer that was a giant ad for 7 Up.
Chocolate printer makes 3D molds of your edible visions
3D has become an industry buzzword du jour. Tack that little epithet onto a consumer-facing product and voila!, you get to charge higher prices for its virtual premium. Well, it looks like a bunch of folks across the pond caught on and decided to throw a little cocoa powder into the mix. Funded by the Research Councils UK's Digital Economy program with oversight by the Engineering and Physical Sciences Research Council, as well as being led by the University of Exeter, the University of Brunel and software developer Delcam -- talk about too many cooks -- the tech that previously brought metal and plastic products to life is getting a chocoholic makeover. Using specially designed temperature and heating controls, the printer takes uploaded 3D CAD designs and turns them into the stuff of your sweet toothed dreams. Although you won't be seeing this printer at a boutique near you, there are plans for a made-to-order retail site that'll let you contribute homemade creations or modify someone else's. We understand if this gets your Valentine's anticipating heart all aflutter, but please don't make any actual chocolate hearts -- that's just gross.
