Medical Xpress / Fatty acids that selectively kill senescent cells open new paths for age-related therapies
New research from the University of Minnesota Medical School has identified fatty acids that selectively induce death in senescent cells—the culprits behind aging and many chronic diseases—opening new avenues for age-related ...
Phys.org / Upper Egypt site has now yielded more than 43,000 inscribed pot sherds, a record-breaking trove of information
A joint archaeological mission by the University of Tübingen and the Egyptian Ministry of Tourism and Antiquities (MoTA) has documented the world's most extensive find of inscribed pottery sherds at the Upper Egypt site ...
Phys.org / Satellite data suggest Sundarbans mangroves are losing resilience
Mangrove forests protect tropical coasts from storms, store large amounts of carbon and provide vital habitats for plants and animals, serving, for example, as nurseries for fish and crabs. They also supply local communities ...
Phys.org / Seeing global trade through the lens of physics
New research from the Complexity Science Hub (CSH) shows why widely used algorithms for measuring economic complexity produce trustworthy results and how these tools may benefit diverse areas such as ecology, social science, ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Phys.org / New study of global reef growth over past 12,000 years offers insights into impact of rising ocean temperatures
Coral reefs over the past 12,000 years grew best when the ocean temperature was 77 degrees Fahrenheit (25 degrees Celsius), according to new research from Florida Tech. Recent ocean warming and regional and local disturbances ...
Phys.org / US weather to go nuts with blizzard, polar vortex, heat dome, atmospheric river all at once
Nearly every part of the United States is getting walloped by wild weather or just about to be.
Tech Xplore / Shortest paths research narrows a 25-year gap in graph algorithms
Most of you have used a navigation app like Google Maps for your travels at some point. These apps rely on algorithms that compute shortest paths through vast networks. Now imagine scaling that task to calculate distances ...
Phys.org / Turning penicillin into a lethal force against bacteria again
When many disease-causing bacteria encounter penicillin, they are not always destroyed right away, shifting into a temporary survival state called antibiotic tolerance. This state allows them to withstand drug levels that ...
Phys.org / Selfish sperm hijack Overdrive gene to kill healthy rivals
A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery—how "selfish chromosomes" cheat the rules of genetic inheritance. The researchers found that rogue chromosomes hijack ...
Phys.org / Seals and sea lions provide clues to evolution of vocalization
Neuroscientists have uncovered new insights into a key evolutionary question: Why can humans talk when most animals can't? The journal Science published the research led by Emory University and the New College of Florida. ...
Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
