Roller coaster superconductivity discovered

Superconductors are more than 150 times more efficient at carrying electricity than copper wires. However, to attain the superconducting state, these materials have to be cooled below an extremely low, so-called transition ...

Cell aging can be slowed by oxidants

At high concentrations, reactive oxygen species—known as oxidants—are harmful to cells in all organisms and have been linked to aging. But a study from Chalmers University of Technology, Sweden, has now shown that low ...

Diamonds may not be so rare as once thought

Diamonds may not be as rare as once believed, but this finding in a new Johns Hopkins University research report won't mean deep discounts at local jewelry stores.

Silicon oxide memories transcend a hurdle

A Rice University laboratory pioneering memory devices that use cheap, plentiful silicon oxide to store data has pushed them a step further with chips that show the technology's practicality.

Which came first: Complex life or high atmospheric oxygen?

We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But how crucial were high oxygen levels to the transition from simple, single-celled life forms to the ...

Six degrees of nuclear separation

Argonne scientists look to 3-D printing to ease separation anxiety, which paves the way to recycle more nuclear material.

Ultrathin copper-oxide layers behave like quantum spin liquid

(PhysOrg.com) -- Magnetic studies of ultrathin slabs of copper-oxide materials reveal that at very low temperatures, the thinnest, isolated layers lose their long-range magnetic order and instead behave like a "quantum spin ...
