COVID-19 often goes undiagnosed in hospital workers; virus may impair heart functions

A high proportion of COVID-19 infections among U.S. healthcare personnel appear to go undetected, according to a report on Monday in the Morbidity and Mortality Weekly Report of the U.S. Centers for Disease Control and Prevention. Between April and June, among more than 3,000 frontline workers in 12 states, roughly 1 in 20 had antibody evidence of a previous COVID-19 infection, but 69% of those...

Getting ahead isn't a nasty business, US study reveals

Researchers found ‘nice, generous’ people advanced at work just as much as bulliesThe question has puzzled humans from the earliest philosophers to the ranks of home workers who have swapped water cooler gossip for rants on Zoom: does being a jerk help people get to the top?Now, after a study lasting more than a decade, researchers believe they finally have the answer. Nasty colleagues are no...

Discovery of an ancient dog species may teach us about human vocalization

In a study published in PNAS, researchers used conservation biology and genomics to discover that the New Guinea singing dog, thought to be extinct for 50 years, still thrives. Scientists found that the ancestral dog population still stealthily wanders in the Highlands of New Guinea. This finding opens new doors for protecting a remarkable creature that can teach biologists about human vocal...

Researchers develop molecule to store solar energy

Researchers at Linköping University, Sweden, have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption. The current results have been published in the Journal of the American Chemical Society (JACS).

Demonstrating the dynamics of electron-light interaction originating from first principle

With the highest possible spatial resolution of less than a millionth of a millimeter, electron microscopes make it possible to study the properties of materials at the atomic level and thus demonstrate the realm of quantum mechanics. Quantum-physical fundamentals can be studied particularly well by the interactions between electrons and photons. Excited with laser light, for example, the energy,...
