Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

Charge change: How electric forces vary in colloids

When calculating electrokinetic force, the convention has been to assume that there is no relative velocity of the fluid compared to the surface, which holds true for hydrophilic surfaces. However, this needs to be reconsidered ...

Climate change in the Southern Hemisphere

On its mission "SouthTRAC," the German research aircraft HALO will investigate the southern atmosphere and its effects on climate change in September and November 2019. Researchers from Goethe University will also be on board.

Image: Avalanche season on Mars

Every spring, the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.

Ages of the Navajo Sandstone

The real Jurassic Park was as an ancient landscape home to a vast desert covered mostly in sand dunes as far as the eye could see, where dinosaurs and small mammals roamed southern Utah. The Navajo Sandstone is known for ...

Scientists demonstrate how to improve steel properties

Scientists from Tomsk Polytechnic University have updated the alloying process, i.e. improving the properties of metal with impurities, which not only enhances the wear resistance of materials but also provides new qualities ...
