A study tracking more than 8,200 adults for 24 years found that higher body mass index was associated with faster declines in memory, overall cognitive performance and executive function. The relationship was most pronounced among adults over 65, though the researchers say the findings do not prove that excess weight directly causes cognitive decline.

Spain’s remaining glaciers lost more than two metres of thickness on average in 2026, as a prolonged, exceptionally warm summer accelerated melting. Researchers say it is now possible to reach Aneto’s summit without crossing ice.

Results from all four major Large Hadron Collider collaborations point to quark-gluon plasma forming in oxygen and neon collisions, challenging the view that the state requires collisions between very heavy nuclei.

A theoretical study finds that extreme rotation may create a narrow route for a black hole to divide, though the conditions needed remain uncertain and exceptionally demanding.
