In a new study, Hao Yan, director of the Center for Molecular Design and Biomimetics at Arizona State University's Biodesign Institute presents a clever means of localizing and confining enzymes and the substrate molecules they bind with, speeding up reactions essential for life processes.

Researchers in Japan and France artificially created such unique 1D nano electronic systems on the surface of a solid, and observed the 1D electronic state (energy and kinetic momentum of electrons) by analyzing photo-emitted electrons from the sample, and verified the electronic structure. This group's research will help elucidate the mystery of unique electronic properties of 1D nano metals and provide, for example, information helpful for the prediction of electrons confined in extremely fine metal nanowires used in next-generation semiconductor devices.

New, detailed maps of the world's natural landscapes created using NASA satellite data could help scientists better predict the impacts of future climate change.

Phagosomes carried by the Motors initially move in a back-and-forth manner near the cell periphery, and mature by fusing with other compartments. As time passes, there is a switch that causes the phagosomes to move in an almost unidirectional manner towards the cell centre. Here, they fuse with acidic lysosomes so that the pathogen can be degraded.

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first known statistical theory for the toughness of polycrystalline graphene, which is made with chemical vapor deposition, and found that it is indeed strong (albeit not quite as strong as pristine monocrystalline graphene), but more importantly, its toughness--or resistance to fracture--is quite low. Their study, "Toughness and strength of nanocyrstalline graphene," was published recently in Nature Communications.

A team of researchers from the Faculty of Physics of Moscow State University in cooperation with Russian and foreign colleagues learnt to grow organic semiconductor crystals with extremely high light-emitting efficiency that promise a bright future for wet-processed organic optoelectronics.

This is a cell (container) where the electrons on liquid helium experiments are conducted.

The new nanoscale manufacturing process draws zinc to the surface of a liquid, where it forms sheets just a few atoms thick.
