Scientists find new materials capable of self-propulsion

Imagine a rubber band that could snap itself many times over, or a small robot that could jump up a set of stairs propelled...

Mysterious x-rays may be first sign of ghost particles

Mysterious X-rays detected from nearby neutron stars may offer the first evidence of axions, hypothetical particles that could help unravel secrets about dark matter,...

How heavy is dark matter? it is tighter than previously thought

Scientists have calculated the mass range for dark matter - and it's tighter than the science world thought. Their findings - due to be published...

New technique builds super-hard metals from nanoparticles

This gold "coin" was made from nanoparticle building blocks, thanks to a new technique developed by Brown University researchers. Metallurgists have all kinds of ways...

Scientists find new state of matter in a one-dimensional quantum gas

As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his...

How short circuits in lithium metal batteries can be prevented

There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there...

Excess X-rays from neutron stars could lead to discovery of new particle

A team of scientists including a University of Michigan researcher have found that mysterious X-rays detected from nearby neutron stars may be the first...

NASA’s Fermi space telescope offers best look ever at giant flare

An intense flash of light from an erupting neutron star in a nearby galaxy in April 2020 has given astronomers their first clear look...

Scientists ‘flash’ new 2D materials

Rice University scientists have extended their technique to produce graphene in a flash to tailor the properties of other 2D materials. The labs of chemist...

Why the universe has less ‘antimatter’ than matter

It’s one of the greatest puzzles in physics. All the particles that make up the matter around us, such electrons and protons, have antimatter versions...
