Earth's deep mantle flows dynamically

As ancient ocean floors plunge over 1,000 km into the Earth's deep interior, they cause hot rock in the lower mantle to flow much more dynamically than previously thought, finds a new UCL-led study.

Running an LED in reverse could cool future computers

In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away.

A wrench in Earth's engine

Researchers at CU Boulder report that they may have solved a geophysical mystery, pinning down the likely cause of a phenomenon that resembles a wrench in the engine of the planet.

'Negative capacitance' could bring more efficient transistors

Researchers have experimentally demonstrated how to harness a property called negative capacitance for a new type of transistor that could reduce power consumption, validating a theory proposed in 2008 by a team at Purdue ...

Voltage-driven liquid metal fractals

Researchers from North Carolina State University have found that gallium indium (EGaIn), a liquid metal with one of the highest surface tensions, can be induced to spread and form patterns called fractals with the application ...
