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 ...

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.

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 ...

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.

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.

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 ...

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 ...

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.

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 ...

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 ...

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 ...

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, ...
