Graphene-fed silkworms can spin super threads
Turns out graphene, the wonder material with so many potential applications, is also the secret sauce to making tougher silk. A team of scientists from Tsinghua University in Beijing successfully created silk that's twice as tough simply by feeding the material to silkworms. In order to do so, they coated leaves with a solution that contains either carbon nanotubes or graphene. Carbon nanotubes are essentially rolled up graphene, which is a single layer of tightly packed carbon atoms. The researchers opted for the feeding method, because it's much simpler and more environmentally friendly than treating the final product in chemicals.
Researchers are using silk cocoons to store blood samples
When doctors draw blood for analysis, it's vital that the sample either be immediately examined or refrigerated. That's because the proteins which indicate various diseases will either be destroyed by enzymes in the blood or deformed by ambient heat. Either way, the sample quickly becomes useless if you leave it sitting out. However a team of researchers from Tufts University have developed a new way to store samples without having to put them on ice by using silkworm cocoons.
