British intelligence services have asked lawmakers to change surveillance rules so they can use personal data to train artificial intelligence systems. The agencies say current safeguards and legal limits prevent them from applying modern AI tools to very large datasets, which they argue reduces their ability to detect threats and process communications quickly. They are proposing legal adjustments to allow broader automated analysis while keeping some privacy protections in place.

China's Chang'e-4 lander touched down on the Moon's far side in January 2019. Using instruments including ground-penetrating radar, the mission collected subsurface profiles near its landing site. A team writing in the Journal of Geophysical Research: Planets reports the top roughly 130 feet (about 40 metres) of the surface is layered—alternating dust, soil and broken rock—and that a buried impact crater lies within those layers.

Researchers at King’s College London have reported links between irregular sleep patterns and changes in the gut microbiome. The study focused on “social jet lag,” where people shift their sleep timing between workdays and free days. Even a 90‑minute difference in the midpoint of sleep was associated with a microbiome profile that other studies have connected to poorer health, and the team also found associations with diet quality, eating habits and inflammation.

Spain's annual Tomatina festival draws thousands each year to the town of Buñol, where participants playfully pelt one another with overripe tomatoes. This year about 15,000 people, many tourists, threw roughly 120 tonnes of fruit, turning streets and buildings into red pulp. The event lasts about an hour, and people commonly wear goggles and old clothes; there is a small participation fee of about €12 to help manage the crowd.
