Summary: New research finds that dogs exposed to human stress odors make more ‘pessimistic’ choices, indicating a negative emotional state. The study shows how human stress affects dogs’ learning and perception of ...

Quantum chromodynamics (QCD) is the theoretical framework for studying the forces within atomic nuclei and their constituent protons and neutrons. A major part of QCD research involves how quarks and gluons are contained...

Researchers have discovered that neuropeptides, not neurotransmitters, are the primary messengers in the brain's fear circuit. This finding could lead to better painkillers and treatments for fear-related conditions. Usi...

Using satellite data, researchers identified hundreds of glacial lakes in Greenland that flooded their frozen shores over the past decade - helping speed up global sea level rise

Atomic nuclei come in different shapes, varying from football-like ("prolate") to pancake-like ("oblate"). Prolate and oblate shapes have different moments of inertia. This is a body's resistance to having its speed of r...

The old saying "the dose makes the poison" also holds true for ultraviolet (UV) light. While UV light is essential for vitamin D production, it is also important in phototherapy, several industrial processes, and plant g...

The tempo of the songs released by artists changes as they age, according to a study of more than 200 musicians with careers spanning over 20 years

There may be ways to work with your body's natural daily and monthly cycles to get the maximum benefits from workouts and avoid injury

Researchers from Tokyo Metropolitan University have devised a way to measure both the temperature and velocity profiles of fluid in a convective plume at millimeter length scales in 3D. They combined near-infrared absorp...

A better understanding of what happens to our bodies when we get fitter can unlock ways to speed up the journey - and it might be simpler than you think

Sea-floor nodules raise oxygen levels in the deep ocean, suggesting they may have a valuable role in ecosystems and adding to concerns about the impact of deep-sea mining

Humans and chimpanzees both take part in rapid social exchanges, suggesting some foundational principles of language may have evolved earlier than previously thought

In a global first, scientists working in the Clarion-Clipperton Zone in the North Pacific Ocean have found that metallic nodules on the seafloor produce their own oxygen, dubbed "dark oxygen."

Truncated conical shells are essential in industries such as aerospace and marine engineering, where understanding their dynamic behavior is crucial. Traditional research has primarily focused on cylindrical shells, leav...

Ultraprocessed foods have been tied to various health risks -- but what are they, exactly?

What's the secret to Homo sapiens' success as a species?
