An experimental loop for simulating nuclear reactors in space
Nuclear thermal propulsion, which uses heat from nuclear reactions as fuel, could be used one day in human spaceflight, possibly even for missions to Mars. Its development, however, poses a challenge. The materials used must be able to withstand high.....»»
Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactions
The reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron.....»»

How NASA"s Roman mission will hunt for primordial black holes
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so f.....»»
Advanced experimental setup expands the hunt for hidden dark matter particles
Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like collisions, research.....»»
Why do metaphors of space help us understand time?
Expressions linking space to time are a common part of our day to day lives. You might say the morning "flew by," or that school exams are "fast approaching." Right now, you might say summer is "just around the corner," while anyone with the vaguest.....»»
Video: Using a hopping robot for asteroid exploration
One day the SpaceHopper will be deployed on space missions to explore relatively small celestial bodies such as asteroids and moons. These are thought to contain valuable mineral resources that could be of use to humankind in the future. The explorat.....»»

Identifying priorities to leverage smart digital technologies for sustainable crop production
Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. Researchers from the PhenoRob Cluster of Excellence at the Unive.....»»
As business districts evolve post-pandemic, repurposing old or empty spaces should be on the drawing board
The COVID-19 pandemic and the hybrid work patterns it fostered have changed the way we think about office space, and central business districts in general. While fears of urban center "ghost towns" may have been premature, many cities around the worl.....»»
