Tiny tool measures heat at the nanoscale

How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials ...

Diamond as a building material for optical circuits

The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical and mechanical properties. ...

Decoding the age of the ice at Mars' north pole

Mars' north pole contains a large ice cap made up of many layers of frozen water. Like ice cores on Earth, those layers offer a tantalizing record of climate on Mars over the past several million years. The first step in ...

Goldstone radar snags images of asteroid 2013 ET

(Phys.org) —A sequence of radar images of asteroid 2013 ET was obtained on March 10, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., when the asteroid was about 693,000 ...

Tracking ocean microplastics from space

New information about an emerging technique that could track microplastics from space has been uncovered by researchers at the University of Michigan. It turns out that satellites are best at spotting soapy or oily residue, ...
