Planets need more water to support life than scientists previously thought

Economic instability—including job loss, food insecurity, eviction and homelessness—is strongly associated with higher rates of violence among California adults, according to a new statewide survey led by the University of California San Diego. The findings come from the 2025 California Violence Experiences Survey (CalVEX).

Sequencing the DNA of all complex life in the UK and Ireland could generate up to almost £3 billion for the economy across agriculture, conservation, and research over the next 30 years, according to a new report.

Quantum technologies like quantum computers are built from quantum materials. These types of materials exhibit quantum properties when exposed to the right conditions. Curiously, engineers can also trigger quantum behavior by manipulating a material's structure; for example, by stacking layers of graphene on top of each other and twisting them to create a moiré pattern, which suddenly turns them into a superconductor.
