The boulders of the Aquidauana River waterfall are up to 4 meters high, yet somehow these catfish (Rhyacoglanis paranensis), which are less than 4 centimeters (1.6 inches) long, manage to scale them like mini Olympic rock …

The ways our eyes explore the world change subtly over time, affected by age and illness. A new study now suggests some of those changes could be used to identify problems with memory and cognition. Researchers from Canada and the West Indies built on previous work by searching for variations in eye viewing patterns in people with and without a …

As the largest object in the Main Asteroid Belt, accounting for more than 39 percent of its total mass, Ceres is the only object in the belt that has undergone hydrostatic equilibrium (aka. became round …

Obsessive–compulsive disorder (OCD) negatively impacts the lives of millions of people worldwide, but more effective treatments could be on the way after researchers were able to identify specific neural biomarkers associated with the condition.

On 16 March 2025, the CHIME radio telescope in Canada recorded a one-off fast radio burst ( FRB) so powerful, astronomers initially weren’t sure about what they were looking at …

The secret to stronger, whiter, healthier teeth has been hidden on the top of our heads this entire time. Researchers from King’s College London have devised a way to use a common protein found in hair to help regenerate tooth enamel; the substance that keeps people’s pearly whites strong and pearly. Teeth aren’t bones – a vital distinction that isn’t …

Cannabis compounds are showing early promise for healthy aging, a new study has found. However, much more research is needed to learn how results might differ depending on the frequency of use and the individual. Researchers in the UK reviewed 18 different studies across 15 years of research (2008 to 2023), involving both animal models and human participants. “By synthesizing …
