Electromagnetic radiation protection shields developed
PHYS.ORG The environment contains electromagnetic radiation and magnetic fields of natural and artificial origin. Even a short electromagnetic pulse is enough to knock any equipment out of operation. Candidate of Sciences (Physics and Mathematics) Aleksey Trukhanov, senior research fellow... 2 weeks
Fast molecular outflow from a dusty star-forming galaxy in the early Universe
Science Magazine Galaxies grow inefficiently, with only a small percentage of the available gas converted into stars each free-fall time. Feedback processes, such as outflowing winds... 2 weeks
Tuning terahertz beams with nanoparticles
PHYS.ORG For years, scientists have dismissed terahertz radiation. Why? There were few ways to control this line-of-sight, nonionizing radiation. However, they saw its potential. For example, it could be used for short-range, high-bandwidth communications for tiny medical and environmental... 2 weeks
Nanophotonic light sails may travel at relativistic speeds
PHYS.ORG One day in the not-so-distant future, light sails may hurtle through space at speeds of around 20% of the speed of light (or 60,000 km/sec), propelled not by fuel but rather by... 2 weeks
