Topological nanoelectronics

Topological insulators are materials with astonishing properties: Electric current flows only along their surfaces or edges, whereas the interior of the material behaves as an insulator. In 2007, Professor Laurens Molenkamp ...

Keeping cool with quantum wells

University of Tokyo researchers have announced a new approach for electrical cooling without the need for moving parts. By applying a bias voltage to quantum wells made of the semiconductor aluminum gallium arsenide, electrons ...

Damaging Sichuan earthquakes linked to fracking operations

Two moderate-sized earthquakes that struck the southern Sichuan Province of China last December and January were probably caused by nearby fracking operations, according to a new study published in Seismological Research ...

Shrinking a medical lab to fit on a fingertip

Identifying a patient's viral infection or diagnosing a blood disorder usually requires a lab and skilled technicians. But researchers at Princeton University have developed a new technology that goes a long way toward replacing ...

When electric fields make spins swirl

We are reaching the limits of silicon capabilities in terms of data storage density and speed of memory devices. One of the potential next-generation data storage elements is the magnetic skyrmion. A team at the Center for ...

Tiny, ancient fossil shows evidence of the breath of life

An international team of scientists from Leicester, Yale, Oxford and London has discovered a rare and exceptionally well-preserved tiny crustacean in 430 million-years-old rocks in Herefordshire, UK. The fossil is a new species ...
