New quantum criticality discovered in superconductivity

Using solid state nuclear magnetic resonance (ssNMR) techniques, scientists at the U.S. Department of Energy's Ames Laboratory discovered a new quantum criticality in a superconducting material, leading to a greater understanding ...

Don't rule out severe global climate change yet

A key metric of global warming is the Earth's "equilibrium climate sensitivity" (ECS), which represents the global surface warming that will accompany a doubling of atmospheric carbon dioxide. For nearly four decades, ECS ...

Pushing the extra cold frontiers of superconducting science

Measuring the properties of superconducting materials in magnetic fields at close to absolute zero temperatures is difficult, but necessary to understand their quantum properties. How cold? Lower than 0.05 Kelvin (-272°C).

The culprit of superconductivity in cuprates

When it comes to high-temperature superconductors, "high" is a relative term. In the field of superconductivity, "high temperature" means anything that can still be superconductive over 30 degrees Kelvin (K), or a balmy -405 ...

A mysterious insulating phenomenon in a superconductor

Leiden physicist Milan Allan and his group have discovered an apparent paradox within a material that has zero electrical resistance. They report trapped charges, although charges should, in theory, keep flowing in the absence ...

An underwater glider for measuring turbulence in Lake Geneva

Huge systems of rotating water masses—called gyres—form in oceans and large lakes. Two EPFL laboratories, working with the University of California, Davis, are using an underwater glider to explore one such gyre in Lake ...

Amazingly 'green' synthesis method for high-tech dyes

Dyes that are also of great interest for organic electronics have recently been prepared and crystallised at Vienna University of Technology. All that is required is water, albeit under highly unusual conditions.
