Phys.org / Orange pigments in birds and human redheads prevent cellular damage, study shows
A pigment that makes feathers and hair orange helps prevent cellular damage by removing excess cysteine from cells. Pheomelanin is an orange-to-red pigment that is built with the amino acid cysteine and found in human red ...
Phys.org / Webb reveals a sample of galaxies with unusual features, nicknamed 'Platypus'
After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have ...
Tech Xplore / Ultra-small, high-performance electronics grown directly on 2D semiconductors
In recent years, electronics engineers have been trying to identify semiconducting materials that could substitute for silicon and enable the further advancement of electronic devices. Two-dimensional (2D) semiconductors, ...
Phys.org / Taming the moral menace at capitalism's core
Digital disruption and the climate crisis are often framed as economic or social challenges. But they force crucial moral questions. Who will be held accountable for the human cost? What will it take to transform business ...
Phys.org / California's largest reservoir rises 36 feet as rains boost water supply statewide
When it rains, it pours. And that's good news for California's water supply.
Medical Xpress / Rise of preterm births in US linked to poverty and race
Researchers at Boston Medical Center, working with colleagues at University of Massachusetts Chan Medical School and Harvard T.H. Chan School of Public Health report that US preterm birth rates rose from 2011–2021 in households ...
Medical Xpress / How stress hormone receptors alter the brain and behavior: Zebrafish study provides insights
Stress, the body's natural response to different types of challenges and daily problems, is an inherently harmless state experienced by most people worldwide. While short-term stress is a common experience and can even be ...
Phys.org / First galaxy-wide wobbling black hole jet discovered in a disk galaxy
Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence yet ...
Phys.org / Ammonites survived asteroid impact that killed off dinosaurs, new evidence suggests
In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished ...
Phys.org / Radio waves enable energy-efficient AI on edge devices without heavy hardware
As drones survey forests, robots navigate warehouses and sensors monitor city streets, more of the world's decision-making is occurring autonomously on the edge—on the small devices that gather information at the ends of ...
Phys.org / What past global warming reveals about future rainfall
To understand how global warming could influence future climate, scientists look to the Paleogene Period that began 66 million years ago, covering a time when Earth's atmospheric carbon dioxide levels were two to four times ...
Phys.org / Most people believe climate change primarily affects others
Research conducted by researchers at the University of Gothenburg shows that people tend to rate their own risk of being affected by climate change as lower than that of others. This perception may reduce individuals' willingness ...
