Scientists hope that two-dimensional materials such as graphene or molybdenum disulfide will allow Moore’s Law to continue apace once it becomes impossible to make further progress using silicon. A 3-atom-thick microchip developed by researchers at the Vienna University of Technology (VUT) may be the first example of 2D materials following the seemingly inexorable growth in the number of transistors in integrated circuits that Gordon Moore observed decades ago.
A young flamingo demonstrates it’s passive, one-legged stance. (Credit: Rob Felt/Georgia Tech)Flamingos are striking not only for their brilliant pink plumes, but for how they often stand on a single slender leg, even when asleep. Now scientists find that standing on one leg may counter-intuitively require less effort for flamingos than standing on two.
Mouse sperm preserved on the International Space Station for nine months gave rise to healthy pups, a new study reveals. This finding suggests that animals, perhaps including humans, can one day reproduce safely in space, researchers said. This work also raises the possibility of a "doomsday vault" for sperm in space that could help preserve animal species from disasters on Earth, much as the Global Seed Vault in Svalbard, Norway, does for plant species.
