Scientists at the University of Virginia School of Medicine and their collaborators have used DNA to overcome a nearly insurmountable obstacle to engineer materials that would revolutionize electronics.  One possible outcome of such engineered materials could be superconductors, which have zero electrical resistance, allowing electrons to flow unimpeded. That means...

Researchers at the Deakin University in Australia have found that boron nitride, a household chemical used commonly in paints, cosmetics as well as dental cement, could unlock the potential of hydrogen as a fuel, a press release said.  With a looming energy crisis and the threat of climate change caused by...

Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now, for the first time, researchers at the University of California San Diego report near-atomic-resolution snapshots of nitrogenase during catalysis using cryogenic electron microscopy (cryoEM). The...

To journey and return from other planets, future spacecraft may have to do something they’ve never done before: refuel in space. Thanks to a Purdue University experiment, scientists are now beginning to understand how cryogenic liquids behave in zero-gravity, and how this affects the future operation of propellant depots in...

NASA’s Spitzer Space Telescope, launched in August 2003 and decommissioned in January 2020 after more than 16 glorious years of exploration of the universe at infrared wavelengths, was a technical and scientific marvel. Infrared astronomical studies at wavelengths longward of 1 micron, somewhat beyond the limit of human vision at...
