Medical Xpress / Newfound 'switchboard' helps brain form new memories without forgetting older ones
The brain may reuse some cells to store many different memories without mixing them up with or erasing older memories, a new study in mice suggests. Led by NYU Langone Health researchers, the study revealed that about 1 in ...
Phys.org / Could it be aliens? From Cheyava Falls on Mars to exoplanet K2‑18b—here's what scientists really think
It may seem like we are on the verge of discovering alien life. In 2025, a press release stated that we have the "strongest hints yet" of extraterrestrial life on the exoplanet K2-18b. And when talking about a collected sample ...
Phys.org / Rising seas could eventually 'drown' mangroves and release carbon
Mangroves could store less carbon—and even begin releasing it—as sea levels rise, suggests new research in Earth's Future. Mangroves are made up of salt-tolerant plants that grow in coastal areas. They cover less than 1% ...
Phys.org / Terahertz imaging maps spatial chirality in materials with 100-micrometer resolution
In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for "hand," since left and right hands share the ...
Phys.org / On-demand Arctic observations with low-cost balloon systems could sharpen local storm forecasts
Arctic communities are increasingly exposed to dangerous weather events due to climate change and rely on accurate weather forecasts. However, conditions in the lower atmosphere remain poorly observed in the Arctic because ...
Medical Xpress / Alzheimer's gene map expands to 91 loci, revealing 16 previously unknown risk regions
An international collaboration of genetic researchers has identified more than 90 genetic regions associated with the risk of Alzheimer's disease and related dementias. The large-scale meta-analysis reveals new biological ...
Phys.org / Half-ton early bovines roamed 4-million-year-old grasslands in Europe
The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June ...
Medical Xpress / New antibiotic kills drug-resistant bacteria by targeting previously unknown vulnerability
Researchers at McMaster University have discovered a new antibiotic that kills some of the world's most dangerous and drug-resistant bacteria—and does so by targeting a previously unknown vulnerability, opening the door to ...
Phys.org / Egypt fossils show modern ocean fish rose rapidly after dinosaur extinction
The extinction that ended the Age of Dinosaurs is best known for clearing the way for the Age of Mammals on land. Scientists have long suspected that the same catastrophe also transformed life in the seas, opening ecological ...
Phys.org / Magnetic field during catalyst synthesis triples ammonia yield
Applying an external magnetic field during the synthesis of CoFe2O4 electrocatalysts triples the ammonia yield during electrocatalytic conversion. The magnetic field alters the surface states of the spinel oxide thin films, ...
Phys.org / Biodiversity offsetting shows promise in pollinator conservation
Newly created grassland habitats that compensate for nature lost to development can effectively support wild pollinators like bees and hoverflies, according to a first of its kind study in the Netherlands. The findings are ...
Phys.org / Mars mission ends: NASA declares Maven dead after six months of silence
After six months of radio silence, NASA's Maven spacecraft around Mars has been declared dead.
