How defects make permanent magnets even more efficient

Rare-earth magnets are essential for electric motors in vehicles, drones, and trains, forming the backbone of modern, environmentally friendly mobility. These are not simple blocks of metal, but carefully engineered materials with a complex internal nanostructure composed of

Streaks on Mercury show that it is not a 'dead planet'

Although Mercury was geologically active in its early days, today its surface appears almost completely static. This is why it is often perceived as a dead and dry planet. A new study led by Dr. Valentin Bickel from the Center for Space and Habitability at the University of

AI unlocks hundreds of cosmic anomalies in Hubble archive

A team of astronomers has employed a cutting-edge, artificial intelligence–assisted technique to uncover rare astronomical phenomena within archived data from NASA's Hubble Space Telescope. The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each

Amazon Leo satellites exceed brightness limits, study finds

Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server has found that satellites from Amazon's mega Leo

Ocean fronts revealed as key players in Earth's carbon cycle

Narrow bands of ocean covering just over one-third of the world's seas are responsible for absorbing nearly three-quarters of the carbon dioxide that oceans pull from the atmosphere, new research shows. The study, published in Nature Climate Change, reveals ocean fronts play a
