Zwitterionic polymeric sulfur ylides: A new generation of antifouling and bactericidal materials
Bacteria that gather into biofilms on the surfaces of implants, catheters, breathing tubes, and other medical components are a serious health hazard. In the journal Angewandte Chemie International Edition, a research team from the Netherlands has now.....»»
Researchers create optical device that can kill pathogens on surfaces while remaining safe for humans
While it has long been known that ultraviolet (UV) light can help kill disease-causing pathogens, the COVID-19 pandemic has put a spotlight on how these technologies can rid environments of germs. However, the excimer lamps and LEDs that can directly.....»»
DART had a surprising impact on its target, according to recent observations
After NASA's DART mission slammed into asteroid Dimorphous in September 2022, scientists determined the impact caused tons of rock to be ejected from the small asteroid's surface. But more importantly, DART's impact altered Dimorphos' orbital period,.....»»
