A type of cognitive training that tests people's quick recall seems to reduce the risk of dementia, including Alzheimer's disease

A new proof solves a long-standing problem about the doughnut-shaped torus

Paul Erdős was one of the most prolific mathematicians to ever live, known for showing up at the door of others in the field and declaring they should host and feed him while they do maths together. His radical life should be immortalised by Hollywood in a comedy biopic, says columnist Jacob Aron

Earthquake swarms can supercharge microbial growth

How do figure skaters like Ilia Malinin keep landing harder and harder jumps?

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely

The problem that large extra dimensions just might solve is called the hierarchy problem, and it’s one of the nastiest outstanding problems in modern physics.

A new study co-led by the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU) and the Department of Atmospheric and Oceanic Sciences at the University of California, Los Angeles (UCLA) reveals that plasma waves traveling along Earth’s magnetic field lines act like an invisible power source, fueling the stunning auroral displays we see in the sky.

What part of Orion is this?

Auroras, shimmering bands of light that shoot through the night sky near the Earth’s poles, can follow patterns known as arcs

NASA’s SpaceX Crew-12 mission is preparing to launch for a long-duration science mission aboard the International Space Station. During the mission, select crew members will participate in human health studies focused on understanding how astronauts’ bodies adapt to the low-gravity environment of space, including a new study examining subtle changes in blood flow.

I always say that one of the things that separates real science from pseudoscience is that while in both you’re allowed to say whatever crazy idea pops into your mind, in real science you’re obligated to take that idea seriously.
