The US Navy has developed a robotic jellyfish nicknamed the Robojelly that powered by the water it swims through. So as long as there water in the oceans, it can perform search and rescue or exploration missions indefinitely. Robojelly uses artificial muscles made from materials known as shape memory alloys that can be warped but will always return to their original shape. This allows them to perform simple expansion and contraction motions similar to how a jellyfish muscles allow it to swi stanley cups uk m. The artificial alloys stanley kaffeebecher that make up the muscles are wrapped in carbon nanotubes and coated with a black powder made of platinum. When exposed to the oxygen and hydrogen in the water, a chemical reaction occurs with stanley tumblers the powder coating that produces heat which in turns powers Robojelly muscles. Because jellyfish are mother nature least intimidating creation, the Navy realizes its robotic version isn ;t going to strike fear into its enemies. But since they can run autonomously with a near unlimited source of power, the Navy could literally flood the ocean with these innocuous underwater spies keeping an eye out for lost ships, or even intruders. [IOP Science via BBC via The Verge] Update: The University of Texas at Dallas reached out to us to let us know the jellyfish was actually developed by its researchers as well as researchers from Virginia Tech. jellyfishScience Pnzs It s a Phone 8230; It s a Tablet 8230; It s Samsung s New Android Things
The stanley cup re seems to be one surefire way to increase longevity in animals. It caloric restriction, which means placing them on a near-starvation diet. We don ;t know if that could work on humans 8230; but fruit flies might be able to give us the answer. There no reason to think that caloric restriction wouldn ;t work on humans, but it not something that easily tested. After all, an experiment designed to test the effectiveness of human caloric restriction would, by design, have to run at least a hundred years, and there are some thorny ethical questions about asking people to spend a century fasting if we ;re not even sure if they would get any longevity benefit out of it. And, of course, there also the question of whether 150 years of caloric-restricted living is really better than 80 normal years. But it would still be good to know just what caloric restriction could do for humans, or better yet to understand the stanley mug underlying processes that make it so effective at increasing longevity. Now, researchers at the Salk Institute for Biological Studies may have found a way to get at an answer. They took some fruit flies and tweaked a gene in their intestinal stem cells. This gene, called PCG-1, is also found stanley taza in humans. This tweak to their genes delayed the aging of their intestines and extended their lifespan by up to fifty percent. Lead scientist Leanne Jones explains why this could be good news for humans: Fruit flies a
