Paramagnetic spins take electrons for a ride, produce electricity from heat

An international team of researchers has observed that local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material—where spins weren't thought to correlate long enough to do ...

Environmental pollution in China decreases

For decades pollution in China has paralleled economic growth. But this connection has been weakened in recent years, according to a new international research study published in the Science Advances journal.

Scientists sharpen gene editing tool

Wake Forest Institute for Regenerative Medicine scientists have fine-tuned their delivery system to deliver a DNA editing tool to alter DNA sequences and modify gene function. The improved "hit and run" system works faster ...

New way to target cancer's diversity and evolution

Scientists have revealed close-up details of a vital molecule involved in the mix and match of genetic information within cells—opening up the potential to target proteins of this family to combat cancer's diversity and ...

Why does tuberculosis find a 65-year-old drug so hard to resist?

Since its discovery in 1954, there have been almost no recorded cases of tuberculosis becoming resistant to the antibiotic drug D-cycloserine (DCS) in patients. With resistance to many other drugs on the rise, a team of ...

Brain-inspired computing could tackle big problems in a small way

While computers have become smaller and more powerful and supercomputers and parallel computing have become the standard, we are about to hit a wall in energy and miniaturization. Now, Penn State researchers have designed ...

New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction ...

Death toll from Spain floods rises to five

Three more people died as torrential rain and flash floods battered southeastern Spain, raising the death toll to five with the rising waters causing havoc for travellers and forcing 3,500 people from their homes, officials ...

The enigma of bronze age tin

The origin of the tin used in the Bronze Age has long been one of the greatest enigmas in archaeological research. Now researchers from Heidelberg University and the Curt Engelhorn Centre for Archaeometry in Mannheim have ...

NASA's WFIRST will help uncover the universe's fate

Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68% of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the nature of dark energy is ...
