However, older adults should avoid using fans in extremely hot and dry conditions. New collaborative research by the University of Sydney and the Montreal Heart Institute reveals that using a fan in hot, humid weather can reduce cardiac strain in

The fossilized leg bone of a giant “terror bird” discovered in Colombia provides new insights into ancient South American ecosystems, suggesting the bird was a major predator in a once-lush region millions of years ago. A team of researchers, including

Gas swirling around black holes forms disks that are among the most effective energy converters in the universe, emitting light and jets of plasma. Recent simulations have shown that as black holes spin, these disks can wobble, changing the direction

The new research suggests that this dinosaur's armor was adapted for fighting between members of Borealopelta markmitchelli.

Potentially deadly comets could be spotted many years in advance by following the meteoroid trails they leave near Earth, new research shows.

A ghostly white angular roughshark found near Sazan Island, Albania, is the first example of leucism ever recorded in the species.

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from

On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA's Atmospheric Waves Experiment (AWE), recorded enormous swells in the atmosphere that

When torrential rains and powerful winds hit densely populated coastal regions, whole cities can be destroyed—but governments and residents can take precautions with sufficient warning.

Scientists routinely build quantitative models — of, say, the weather or an epidemic — and then use them to make predictions, which they can then test against the real thing. This work can reveal how well we understand complex phenomena,

This changed everything.

We humans are imperfect.

The horror.

New research into a chemical from a caterpillar fungus, known for its potential as a cancer treatment, has shown how it interacts with genes to disrupt cell growth signals. This finding marks a promising step toward developing new cancer drugs.
