As space travel extends to greater duration and distance, missions may require a propellant refill in space. To achieve this, spacecraft may require larger tanks and efficient refueling along with tanks that have the capability of isolating propellant from ullage fluid (a gas and vapor mixture) during a vent. The goal of this Challenge is to develop a novel solution for the venting of ulla

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to ten times easier to correct. This will significantly accelerate progress towards large-scale quantum computers capable of tackling the world's most challenging computational problems, the researchers said. Led by Princeton University's Jeff Thompson, the team demonstrated a wa

EX-Fusion Inc. has established a Collaborative Research Cluster focused on advancing liquid metal devices for the realization of commercial laser fusion reactors in collaboration with Tokyo Institute of Technology. The signing ceremony to formalize this partnership was held on October 11, marking the official commencement of their joint efforts. The 'EX-Fusion Liquid Metal Collaborative Re

New research, based largely on information from the Copernicus Sentinel-1 and ESA’s CryoSat satellite missions, has revealed alarming findings about the state of Antarctica's ice shelves: 40% of these floating shelves have significantly reduced in volume over the past quarter-century. While this underscores the accelerating impacts of climate change on the world's southernmost continent, the picture of ice deterioration is mixed.
