Phys.org / Chinese cave traces Denisovan hunting and adaptation across 120,000 years
An ancient cave in southwestern China has revealed new evidence about how Denisovans—an ancient human relative—lived, survived and adapted over more than 100,000 years.
Phys.org / JWST finds extreme star-forming galaxies masquerading as faint quasars
A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space Telescope observations of the galaxies, seen ...
Medical Xpress / Trends reported in vaccination coverage for adolescents for 2025
Diphtheria toxoid and acellular pertussis (Tdap) and quadrivalent meningococcal conjugate (MenACWY) vaccination coverage for adolescents remained around 90% in 2025, and human papillomavirus (HPV) vaccination did not increase ...
Phys.org / Under pressure: How a deep-sea protein adapts to an extreme environment
Life in the deep sea is under immense pressure—literally. Such extreme conditions can disrupt the delicate structures of proteins essential to life. Yet somehow, the proteins in deep-sea creatures remain functional. This ...
Medical Xpress / Stress hormone timing creates a different kind of obesity, study suggests
Obesity caused by disrupted stress-hormone rhythms is metabolically very different from obesity caused by a high-fat diet, according to a new preclinical study by Weill Cornell Medicine investigators. The researchers found ...
Phys.org / 'CRISPR-Combo' system speeds regeneration of hard-to-breed perennial crops
Editing a plant's genes is only half the battle. Before a new, improved trait can ever reach a farmer's field, scientists must be able to grow a whole plant from just a few edited cells—a process that can be slow, unreliable ...
Tech Xplore / Brain-inspired computing: Using noise to regulate information flow in neural networks
Researchers have developed a learning mechanism that uses the natural variability of neural activity—often dismissed as random "noise"—to understand how synapses buried deep inside brain networks—or brain-inspired devices—can ...
Medical Xpress / Blocking a protein may reduce buildup of harmful aging cells
A team led by Cedars-Sinai Health Sciences University investigators has identified a protein that may hide aging cells from the body's immune system, allowing them to build up and contribute to age-related health problems.
Phys.org / Release of open AI model trained on 17 years of lunar data maps ice, craters and volcanoes
NASA is bringing artificial intelligence to the study of the moon, helping researchers transform how they analyze its surface. In an ongoing collaboration with IBM Research and several academic institutions, NASA has launched ...
Phys.org / Rare pulsar unleashes 114 giant pulses in a single hour
Astronomers have detected extreme, never-before-seen behavior from a rare kind of pulsar and stumbled on a surprising link to one of astronomy's biggest current mysteries. Using 174 hours of radio observations, researchers ...
Phys.org / 'White graphene' reshaped at the atomic scale with tailor-made nanopores
A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride—the electrically insulating counterpart to graphene, also known as "white graphene"—can ...
Phys.org / Mercury is shrinking more than we thought
Mercury's surface is riddled with wrinkles, evidence of a once-larger planet that has shrunk over time. A new study finds that Mercury may have contracted 10% to 30% more than previously thought—a loss of nearly 12 miles ...
