William Kaelin, Jr., Peter Ratcliffe and Gregg Semenza share the 2019 Nobel Prize in Physiology or Medicine “for their discoveries of how cells sense and adapt to oxygen availability.” New therapies for cancer and conditions such as anemia are in the pipeline, based on these discoveries...
The 2019 Nobel Prize in Physiology or Medicine goes to William G. Kaelin, Jr., Peter J. Ratcliffe and Gregg L. Semenza “for their discoveries of how cells sense and adapt to oxygen availability.” They identified molecular machinery that regulates gene activity in response to changing levels of oxygen...
DNA from the teeth of medieval plague victims indicates the pathogen likely first arrived in eastern Europe before spreading across the continent.
Scientists found eight species of nematodes living in California’s harsh Mono Lake—quintupling the number of animals known to live there. Christopher Intagliata reports.
Scientists isolate and synthesize two compounds that can fight common, and even drug-resistant, infections
By engineering mutations into fruit flies, scientists reconstructed how the bright orange butterflies came to tolerate milkweed toxins
Tiny insects called treehoppers produce very different mating songs at higher versus lower temperatures, but the intended recipient still finds the changed songs attractive.
Adult corals can reshuffle their symbiotic algae species to adapt to warming waters—and, it appears they can pass those adaptations on. Christopher Intagliata reports.
Gene transcription is one of life’s most fundamental processes. For the first time, researchers have viewed it in real time in a living cell.
