Second-generation of powerful X-ray laser fires for the first time

The Linac Coherent Light Source (LCLS) is an extremely powerful X-ray laser – and now it's about to get even more powerful. The second generation of the instrument has now achieved first light, with scientists demonstrating fine control of the beam.

Tiny quantum fluctuations observed moving 40-kg mirror

Classical physics describes how large objects and systems work on an everyday scale, while quantum physics describes the “spooky” subatomic world. Now scientists have observed a rare crossover where a quantum fluctuation affected a macroscale object.

Dark matter: What is it, how do we know it’s there and will we find it?

There’s invisible, undetectable stuff all around us, and we call it dark matter. There’s plenty of evidence that this stuff is very real, but what exactly is dark matter? How do we know it’s there? And how are scientists looking for it?

Nano-motor of just 16 atoms runs at the boundary of quantum physics

Researchers at Empa and EPFL have created one of the smallest motors ever made. It’s composed of just 16 atoms, and at that tiny size it seems to function right on the boundary between classical physics and the spooky quantum realm.

New explanation for Antarctic mystery doesn’t need “parallel universe”

Headlines lately have been screaming about how scientists in Antarctica have discovered evidence of a parallel universe where time runs backwards. While we seriously wish that was true, a new study has put forward a more realistic explanation.

Whirling, glassy magnets found to be new state of matter

Most of us know the four classical states of matter – solid, liquid, gas and plasma – but there’s a whole world of exotic states out there. Now, physicists have identified a new one named “self-induced spin glass,” which could be used in AI platforms.

Parts of the universe may be expanding faster than others

One of the core components of cosmology is the understanding that the universe is expanding evenly in all directions. But new X-ray observations now suggest that this may not be the case after all – certain areas may be expanding faster than others.
