Far-ultraviolet LED can kill bacteria and viruses efficiently without harming humans
A highly efficient LED that is deadly to microbes and viruses but safe for people has been engineered by three RIKEN physicists. It could one day help countries emerge from the shadows of pandemics by killing pathogens in rooms full of people......»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Analysis of heterostructures for spintronics shows how two desired quantum-physical effects reinforce each other
Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create a.....»»
