Engineers at the University of California, Berkeley, have developed a pressure-sensitive electronic material from semiconductor nanowires that will help overcome a key challenge in robotics: adapting the amount of force needed to hold and manipulate a wide range of objects. The artificial skin has been dubbed “e-skin” and the researchers say it is the first […]
Howard Hughes Medical Institute researchers have shown that when females are more promiscuous, male genes have to work harder. They determined that a protein controlling semen viscosity evolves more rapidly in primate species with promiscuous females than in monogamous species. The research – published in Nature Genetics – demonstrates that sexual competition among males is […]
