Why X-rays could become a lot more personal

X-rays could be about to change. Since its discovery at the end of the 19th century, the radiation has provided a window into the inner workings of the body, and later gave us the power to "see" inside everything from buildings ...

What do physicists mean when they talk about nothing?

Philosophers have debated the nature of "nothing" for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology ...

Breaking down the Wiedemann-Franz law

A study exploring the coupling between heat and particle currents in a gas of strongly interacting atoms highlights the fundamental role of quantum correlations in transport phenomena, breaks the Wiedemann-Franz law, and ...

Magnetic vortices observed in haematite

Vortices are common in nature, but their formation can be hampered by long range forces. In work recently published in Nature Materials, an international team of researchers has used mapped X-ray magnetic linear and circular ...

Study finds flaw in emergent gravity

In recent years, some physicists have been investigating the possibility that gravity is not actually a fundamental force, but rather an emergent phenomenon that arises from the collective motion of small bits of information ...

Quantum chains in graphene nanoribbons

Empa researchers, together with colleagues from the Max Planck Institute for Polymer Research in Mainz and other partners, have achieved a breakthrough that could eventually be used for precise nanotransistors or, in the ...
