Scientists have identified a sub-atomic particle that could have formed the ‘dark matter’ in the Universe during the Big Bang. Nuclear physicists are putting forward a new candidate for dark matter – a particle they recently discovered called the d-star hexaquark.

Up to 80% of the Universe could be dark matter, but despite many decades of study, its physical origin has remained an enigma. While it cannot be seen directly, scientists know it exists because of its interaction via gravity with visible matter like stars and planets. Dark matter is composed of particles that do not absorb, reflect or emit light.

Now, nuclear physicists at the University of York are p...

Rensselaer team finds solution to persistent problem facing potassium-metal batteries. Researchers demonstrate how they can overcome dendrites to create a metal battery that performs nearly as well as a lithium-ion battery, but relies on potassium – a much more abundant and less expensive element.

If you were to look inside a lithium-ion battery you’d typically find a cathode made of lithium cobalt oxide and an anode made of graphite. During charging and discharging, lithium ions flow back and forth between these two electrodes.

In this setup, if researchers were to simply replace lithium cobalt oxide with potassium cobalt oxide, performance would drop...

Some of the extremely low-density, “cotton candy like” exoplanets called super-puffs may actually have rings, according to new research published in The Astronomical Journal by Carnegie’s Anthony Piro and Caltech’s Shreyas Vissapragada

Super-puffs are notable for having exceptionally large radii for their masses – which would give them seemingly incredibly low densities...
