About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators.
Inspired by insects that suck nutrients directly from plant veins, physicists from DTU have studied whether valuable chemical substances can be harvested directly from the cells of plants. Using a harvester measuring only a few microns, they have now achieved a technological breakthrough.
Killer flies can reach accelerations of over 3g when aerial diving to catch their prey - but at such high speeds they often miss because they can t correct their course.

LED lightbulbs offer considerable advantages over other types of lighting. Being more efficient, they require much less electricity to operate. They do not give off unwanted heat the way old-school incandescent bulbs do, and the best of them long outlast even fluorescent lightbulbs.
But LEDs are not problem-free. Questions linger over suspected links between health concerns such as fatigue, mood disorders, and insomnia from overexposure to the blue-tinted light produced by today s standard LED bulbs. Plus, higher prices can prompt lightbulb shoppers to weigh other options.
A University of Houston research team led by Jakoah Brgoch, associate professor of chemistry in the College of Natural Sciences and Mathematics and principal investigator in the Texas Center for Superconductivity, is developing an LED bulb that emits most of its energy from the safer violet segment of the visible light spectrum. Instead of just masking the blue light, they are developing a unique class
