Workers sweated in choking heat and pupils stayed home Tuesday as an early-summer heat wave smothered much of Europe, with France suffering its hottest day on record.
When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of Chemistry, researchers are instead thinking about how a drug behaves after it
Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions suggest, according to new University of Bristol-led research. The study is published in the journal Paleobiology.
Which farming strategies can help agricultural operations better manage yield risks caused by climate change and fluctuating prices in the agricultural product market? A new study by ZALF published in the journal Agricultural Systems uses model calculations to show that farms
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) light. Spanning frequencies between 0.3 and 20 THz,
In a recent study, Manish Garg, independent group leader at Max Planck Institute for Solid State Research (MPI FKF), succeeded in probing the local properties of bright and dark excitons in the organic superconductor copper naphthalocyanine (CuNc). The findings are published in
A new algorithm could drive breakthroughs in understanding cancer, Alzheimer's disease and other potentially fatal conditions. Researchers from the University of Waterloo developed the machine-learning algorithm, called RNovA, to detect changes in the proteins in human cells.
In romantic relationships, touch is usually considered part of everyday life: a quick back rub while cooking dinner, a hug after a long day at work or a lingering kiss before falling asleep. It's a simple way to show support, express affection and communicate sexual desire.
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
