Researchers at the Department of Chemistry, American University, used spinach to make a carbon-rich catalyst that can be used to improve the performance of fuel cells and metal-air batteries. IEEE Spectrum reports: The spinach was a used a precursor for high-performance catalysts required for the oxygen reduction reactions (ORRs) in fuel cells. Traditionally, fuel cells have used platinum-based catalysts, but not…

This transforming rover can explore the toughest terrain
A rover trundles over rocky terrain, its four metal wheels clattering along until they encounter a seemingly insurmountable hazard: a steep slope. Down below is a potential trove of science targets. With a typical rover, the operators would need to find another target, but this is DuAxel, a robot built for situations exactly like this.

Finding vaporized metal in the air of an exoplanet
WASP-121b is an exoplanet located 850 light years from Earth, orbiting its star in less than two days—a process that takes Earth a year to complete. WASP-121b is very close to its star—about 40 times closer than Earth to the Sun. This close proximity is also the main reason for its immensely high temperature of around 2,500 to 3,000 degrees Celsius….

Researchers Finally Create Metal Wires Made from Carbon
University of California at Berkeley has made a big announcement: Transistors based on carbon rather than silicon could potentially boost computers’ speed and cut their power consumption more than a thousandfold — think of a mobile phone that holds its charge for months — but the set of tools needed to build working carbon circuits has remained incomplete until now. A…
