They explain that hunting for snot is called the mania of the tillexo rhinoceros. If you eat them, it’s called mucophagia. During our 22,000 daily breathing cycles, the mucus that makes up mucus acts as an essential filter to capture dust and allergens. And what does science say about the risks of snot hunting? Staphylococcus aureus, a germ that can cause infections, is often present in the nose. Picking your nose can increase the risk of bringing Staphylococcus aureus to a wound. Sticking your finger in your nose is also a great way to introduce germs into your body, or spread them around with your dodgy finger. What if we really can’t help it? Wash your hands after using your finger. Until the mucus has completely dried, infectious viruses can remain on the hands. A spider corpse in a robot: a rather horrifying experiment carried out by scientists In a robotics laboratory in Preston, a mechanical engineering student uses spider corpses in her robots. The goal is to make them able to grasp objects. Thanks to their small size, these necrobots could be especially useful for picking up, positioning and sorting small objects. They could be used, for example, for the assembly of electronic components. Using spider carcasses would also generate less waste. This would avoid designing new materials. What an incredible idea! Discovering a dead spider in his laboratory, the head of the experiment wanted to understand why lifeless spiders curl in on themselves. Answer: When alive, spiders use blood pressure to send blood to their legs to stretch them. And it is this mechanism that scientists want to exploit. We know where the North Pacific plastic continent comes from According to Dutch researchers involved in the Ocean Cleanup project, 90% of the waste swirling in the North Pacific vortex comes from just six countries. In 2019, an oceanographic mission carried out jointly by the non-profit company Ocean Cleanup and Wageningen University recovered more than 6,000 pieces of hard plastic debris (> 5 cm) in this notorious North Pacific garbage patch . Since then, these remains have been sorted, counted, weighed and analyzed to determine their origin and age. The researchers found that between 75% and 86% of the identifiable waste came from fishing gear. And where do these plastics come from? From Japan, China, South Korea, the United States of Taiwan and Canada. But this plastic visible on the surface represents only a small fraction of global plastic emissions into the marine environment. Several million tons of mismanaged plastic waste enter the oceans each year from rivers around the world before accumulating on the seabed. The meals of prehistoric humans are partly reconstructed In Great Britain, researchers have just found new clues about the diet of the people who inhabited northern Scotland several thousand years before our era. Numerous pieces of pottery have been found at the bottom of the water surrounding Scotland’s crannogs, which contain surprisingly well-preserved remains. So what did we eat in Scotland 6000 years ago? Thanks to a thorough chemical analysis, scientists understood that this cuisine was elaborate, based on the cooking of cereals in pots, mixed with dairy products, sometimes even with meat! These cooked dishes would be the forerunners of today’s stews.
