(PhysOrg.com) -- Double-core-hole (DCH) states – in which two electrons are ejected from their positions, creating vacancies – occurring at different atomic sites are very sensitive to the chemical environment of ...
A study of electron dynamics timed to millionths of a billionth of a second reveals the damage radiation can do on a molecular level.

Using AstroSat satellite, Indian astronomers have detected strong X-ray pulsations from an X-ray binary pulsar known as 3A 0726-260. The discovery, presented in a paper published April 26 on the arXiv pre-print repository, ...
To study the swiftness of biology—the protein chemistry behind every life function—scientists need to see molecules changing and interacting in unimaginably rapid time increments—trillionths of a second or shorter.
