Salt water flowing over thin layers of rust generates electricity

It’s not unusual to find rust around saltwater, but now the pairing might actually be useful. Researchers at Caltech and Northwestern University have found that electricity can be produced when saltwater flows over the top of thin films of ru… Continue reading Salt water flowing over thin layers of rust generates electricity

Tabletop-sized gravitational wave detector could shed light on dark matter

It can take huge equipment to detect the tiniest things, and that’s particularly true when it comes to gravitational waves. The LIGO detector uses 4-km-long (2.5-mi) arms to pick up distortions just a thousandth of the width of a proton. But … Continue reading Tabletop-sized gravitational wave detector could shed light on dark matter

First detection of polarized radio waves from gamma ray burst sheds light on collapsing stars

The first polarized light from a gamma ray burst seven billion light years away is helping astronomers to gain a better understanding of collapsing stars and other high-energy phenomena. Originating from gamma-ray burst GRB 190114C in the con… Continue reading First detection of polarized radio waves from gamma ray burst sheds light on collapsing stars
