Bright compact ultrabroadband source by orthogonal laser-sustained plasma
Abstract Laser-sustained plasma (LSP) source featuring high brightness and broadband spectral coverage is found to be powerful in various fields of scientific and industrial applications. However, the fundamental limit of low conversion efficiency constrains the system compactness and widespread applications of such broadband light sources. In this paper, we propose an innovative orthogonal LSP to…

Scientists successfully ‘nuke asteroid’ — in a lab mock-up
Scientists and science-fiction writers have long asked whether a nuclear explosion could change the course of an asteroid headed for Earth (artist’s impression).Credit: Detlev Van Ravenswaay/Science Photo Library A blast of X-rays from a nuclear explosion should be enough to save Earth from an incoming asteroid, according to the results of a first-of-its-kind experiment. The…

Q&A: How scientists aim to kill cancers by starving them
Like all living things, cancer cells need to eat, and scientists have long tried to figure out how to starve tumors to death. A lot of that effort has focused on stifling the cells’ ability to digest glucose, a simple sugar thought to be the main food source for cancer. The glucose route has been…
