Researchers re-created the conditions deep inside the Cascadia subduction zone and found that fractured rocks can repair themselves during, or just hours after, slow-motion earthquakes.

Moss spores spent nine months strapped to the outside of the International Space Station, exposed to vacuum, cosmic radiation, temperature swings from minus 196C to 55C, and unfiltered solar ultraviolet light. Over 80 percent survived the ordeal and returned to Earth still capable of growing into new moss plants. This remarkable resilience, demonstrated by one of Earth's earliest land plants, suggests that life's fundamental mechanisms may be far more robust in the face of space conditions than previously imagined.

The world's gravitational wave detectors just wrapped up their longest and most productive observation campaign, capturing 250 new collisions over two years of continuous listening. These ripples in spacetime, created by black holes and neutron stars spiralling into each other across the universe, have given scientists their first direct evidence for Stephen Hawking's 1971 theory about black hole surface areas, revealed second generation black holes born from previous mergers, and detected the most massive black hole collision ever observed. The haul represents over two thirds of all gravitational waves ever detected.

The British physicist also praised a truly inspired footnote in this preprint paper.
