When atoms form molecules, they share their outer electrons and this creates a negatively charged cloud. Here, electrons buzz around between the two positively charged nuclei, making it impossible to tell which nucleus they belong to. They are delocalized. But is this also true for the electrons located closer to the nucleus?
Scientists at the University of Chicago and the University of Santiago in Chile have explained, for the first time, the physics that governs how thin materials at scales millions of times different in thickness make the transition from wrinkles into folds under compression.
MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market, particularly in portable electronics.
Physicists have provided a mechanism by which information can be recovered from black holes -- and the first plausible mechanism for how information might escape from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking.
Thanks to nanostructures that scatter and channel light, electrical engineers are working toward thin-film "single junction" solar cells with the potential for nearly 45 percent sunlight-to-electricity conversion efficiencies. This new effort aims to break the theoretical limit of 31 percent efficiency for conventional single junction cells.
Experiments by physicists end a long-lasting dispute with an answer that apparently satisfies everyone. When atoms form molecules, they share their outer electrons and this creates a negatively charged cloud. Here, electrons buzz around between the two positively charged nuclei, making it impossible to tell which nucleus they belong to. They are delocalized. But is this also true for the electrons located closer to the nucleus?
(The Wistar Institute) Wistar Institute scientists have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development. Based on studies in human melanoma cells, the research paves the way for developing new ways to treat cancer by dampening overactive enzyme activity that leads to uncontrolled tumor growth. The study shows how small-molecule inhibitors can be designed to target a family of signaling proteins, called phosphatidyl-inositol-3-kinases, or PI3Ks.
(Massachusetts Institute of Technology) Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation.
(Case Western Reserve University) Building a machine that moves like a cockroach, salamander, fish or another creature is no easy task. Over 100 of the world's pioneering engineers, biologists and neuroscientists who have contributed to building biologically inspired robots will be on the campus of Case Western Reserve University, June 1-6, to discuss new developments in the field of biorobotics during the Fourth International Symposium on Adaptive Motion of Animals and Machines.
