Phys.org / Why birds ignore Newton: New theory could sharpen models of flocks, crowds and cells
Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are ...
Medical Xpress / A higher-dose flu shot could spare millions of older adults a hospital stay
Influenza is a seasonal condition that causes coughing, sneezing, mild fever and aches in most cases. However, it can sometimes take a serious turn, leading to hospitalization, especially for young children, adults over 65 ...
Phys.org / Slime molds make decisions using internal fluid flows
Despite lacking brains or nervous systems, slime molds are capable of making surprisingly sophisticated decisions: navigating mazes, finding food and even remembering where they found it last time. How they manage to do all ...
Phys.org / Venus flytrap's snap may come from rapid cell wall softening, not water flow
The Venus flytrap (Dionaea muscipula) is a marvel of nature, a highly effective killer that doesn't have to move an inch to capture and kill its prey. It releases a fruity nectar scent to attract flies and other insects. ...
Phys.org / Gulf Stream shifted north during 12,900-year-old cold snap, first direct evidence shows
During an abrupt global cold snap nearly 13,000 years ago, the Gulf Stream ocean current shifted farther north, temporarily disrupting eastern Canada's oceanic ecosystems, a process that could happen again as the climate ...
Phys.org / 'Puffy' super-Neptune emerges 383 light-years away with a density of just 0.4 g/cm³
Using the Subaru Telescope, astronomers have conducted follow-up observations of a recently discovered exoplanet known as TOI-1883 b. Results of the new observations, published June 5 on the arXiv preprint server, indicate ...
Medical Xpress / Fructose sends a weaker satiety signal to the brain than glucose
Researchers at the Monell Chemical Senses Center have found that common dietary sugars fructose and glucose, despite having the same number of calories, communicate with the brain through different gut–brain pathways, a difference ...
Phys.org / Jurassic viral gene may have helped apple snails start laying eggs on land
Pomacea canaliculata, commonly known as the apple snail, is a pest commonly found in Hong Kong's wetlands and farmlands. It feeds on aquatic plants and produces toxic pink egg masses resembling miniature grapes that adhere ...
Phys.org / Lab-grown canine muscle cells offer solution for early therapeutic testing
Before testing new therapies in animals, researchers now have a more efficient starting point—lab-grown canine muscle cells that can help identify what works and what doesn't.
Tech Xplore / New strategy enhances oxygen reduction in zinc-air batteries
Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding ...
Phys.org / Ancient DNA study of post-Roman Europeans reveals emergence of complex new society
A new study from the HistoGenes project, of which Patrick Geary, professor emeritus in the School of Historical Studies, is co-PI, is helping scholars frame a better picture of the early medieval people who inhabited Western ...
Phys.org / New species of Middle Miocene bear-dog described in tribute to Salvador Moyà-Solà
A research team with the participation of the Institut Català de Paleontologia Miquel Crusafont (ICP) has described a new species of extinct carnivore from fossil remains recovered at the Els Casots site (Subirats, Alt Penedès). ...
