Phys.org / Can a long-lived seabird evolve fast enough to avoid extinction under a changing climate?
As the climate changes, species face a critical question: Can they evolve quickly enough to keep pace with their changing environment?
Phys.org / RHIC data reveal intriguing dip in momentum fluctuations in high-density nuclear matter
Scientists using the STAR detector to study particle collisions at the Relativistic Heavy Ion Collider (RHIC) have found an intriguing dip in their data in a relatively unexplored region of the nuclear phase diagram—a map ...
Phys.org / Earth's chorus waves show limited link to rapid electron loss from radiation belts
The Van Allen radiation belts are huge, doughnut-shaped regions of highly energetic charged particles trapped by Earth's magnetosphere. These charged particles play a major role in space weather, so studying them is important ...
Phys.org / The mosquito's transition from vegan to bloodsucker explained
Scents govern most key events in the lives of mosquitoes, and there is extensive research on their sense of smell. A new study reveals how a young female mosquito shifts from focusing entirely on nectar to seeking only blood. ...
Phys.org / AI companions may erode social skills among isolated users, framework suggests
As AI companions become more commonplace, new research from Singapore Management University (SMU) and Duke-NUS Medical School argues that the real question is no longer whether these technologies are beneficial or harmful, ...
Phys.org / Rope, twine and thread: Invisible technologies of the Stone Age
When an abstract-looking ivory artifact emerged from the Hohle Fels cave in southern Germany in 2015, archaeologists didn't know quite what to make of it. Previously, the same cave had yielded what may be the world's oldest ...
Phys.org / AI model predicts peptide bitterness and enables novel flavor design
During the production of fermented products such as kefir, Parmesan, or mountain cheese, as well as in the production of protein powders, bitter-tasting peptides can form, which impair the taste and thus the acceptability ...
Phys.org / A tiny chariot fitting reveals Egyptian glass reached Iron Age Britain
At the end of last year, curators from the Ashmolean Museum in Oxford came to Diamond to learn more about a 2,000-year-old prehistoric artifact. Using the microfocus beamline at I18, researchers unlocked new insights into ...
Phys.org / X-ray method predicts anion behavior, opening path to longer-lasting batteries and AI-assisted chemistry
A new way of measuring how materials interact at the atomic level could help scientists develop better-performing, longer-lasting batteries.
Phys.org / Microcrystal electron diffractometer brings hidden hydrogen into focus
Hydrogen—the lightest atom—does the heavy lifting when it comes to important chemical reactions. It can be stored and released as clean fuel, and its movements help catalysts build medicines, fertilizers and materials. One ...
Phys.org / Bacteria-killing polymers—a new class of antibiotic?
Swimming in the blood, sweat, cells and tears of every human are small proteins known as peptides. Many peptides can kill bacteria on contact, yet the bacteria never seem to evolve resistance to them. Mass-produced peptides ...
Phys.org / Iron complex breaks down stubborn pollutant using light-powered reaction
The molecular culprit behind harmful algal blooms and some groundwater contamination is the same thing that has kept civilization fed for millennia: a stable form of nitrogen called nitrate.
