Two space tech companies, Helios and Eta Space, announced they are joining forces to solve the problem of oxygen in space. If humanity is to have a sustainable presence beyond Earth, reusable methane-fueled rocket systems need liquid oxygen at a ratio of 1:4, so the only cost-effective solution to refueling in orbit is...

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...

In early January 2022, a prototype mag- lev train was rolled out in southwest China’s city of Chengdu, one of the latest developments in magnetic levitation trains. The domestically developed locomotive uses high temperature superconducting and will travel with a designed speed of 620 km/h, according to Southwest Jiaotong University,...
