Phys.org / Overpopulation can impair fertility. A new study explains why
Scientists have reported it for decades: overpopulation can impair reproduction. Crowded chickens lay fewer eggs. Crowded mice have smaller broods. In humans, several studies have associated increased population density with ...
Phys.org / Social mammals live longer—but bigger groups don't add that many extra years
A new study, published in Ecology and Evolution, shows that social living is associated with longer lifespan, but also that the benefits of sociality level off once animals move beyond living in pairs.
Phys.org / Agentic AI could help electron microscopes plan, adapt and analyze experiments
Scientific discovery is often portrayed as the result of long hours alone in a lab, but true science is inherently collaborative. The most robust experimental processes are developed through partnerships across multiple areas ...
Phys.org / Ancient DNA reveals web of marriage and migration in Peru centuries before Inca rule
Long-distance migration along Peru's Pacific coast began at least 800 years ago, centuries before the rise of the Inca Empire and much earlier than previously thought, a new international study reveals.
Phys.org / Bodies in fashion: Diversity is up, but the ideal stays the same
Fashion and media have become visibly more diverse over the past quarter-century. Yet beneath that surface change, a new study suggests that the industry's central female body ideal has barely shifted.
Phys.org / AI-generated fake citations are flooding scientific literature across publications, scientists warn
The citations at the end of a research paper should represent a solid foundation of existing knowledge about a particular field, a pool of peer-reviewed sources built over years of research and study. However, with the increasing ...
Tech Xplore / Unlocking soft robotics control with AI's cousin: Reservoir computing
Soft robotics—machines made of flexible, muscle-like materials—can bend and stretch in fluid ways that put the rigid robots of old sci-fi movies to shame. But the flexibility that lets them pick ripe tomatoes or navigate ...
Phys.org / As corporations race for the stars, we need international collaboration on space governance
The science academies of G7 member countries have identified international space governance as a pressing issue for the G7 Leaders' Summit, to be held from June 15–17 in Evian, France.
Science X / The asteroid that wiped out the dinosaurs may have triggered a global fungal bloom
The asteroid that smacked into our planet about 66 million years ago at the Cretaceous-Paleogene (K/Pg) boundary may have been bad news for dinosaurs, but it was good news for fungi. According to new research published in ...
Tech Xplore / Laser-powered engines may soon support 'intelligent' 6G networks
In a step toward developing next-generation, AI-enabled 6G wireless networks, scientists have demonstrated a laser-driven engine made from an easy-to-manufacture ceramic material that uses white light to move information ...
Phys.org / Ultrafast switching device unlocks low-power optical-to-electrical conversion for AI hardware
Modern energy demands are soaring as technologies like AI and IoT become more common, and researchers have been working hard to develop hardware that can keep up. Now, a team of researchers from the University of Tokyo has ...
Phys.org / Tritium-infused graphene could sharpen the hunt for neutrino mass
While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, ...
