'Nanocable' could be big boon for energy storage

Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors.

"Better" copper means higher-efficiency electric motors

Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher ...

The mast is raised for NASA's Mars 2020 rover

In this image, taken on June 5, 2019, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, take a moment after attaching the remote sensing mast to the Mars 2020 rover in the Spacecraft Assembly Facility's ...

Electric cable bacteria breathe oxygen with unheard efficiency

Ten years ago, researchers at Aarhus University, Denmark, reported the discovery of centimeter-long cable bacteria, that live by conducting an electric current from one end to the other. Now the researchers document that ...
