Creating mental images requires real mental effort, study finds

Researchers have found that deliberately forming "mind pictures" in the imagination draws on genuine cognitive effort rather than happening effortlessly. The work, reported in Nature, adds to understanding of how visual imagination works in the brain. It may help explain why some people find mental imagery tasks taxing or difficult.

Satellite data offers strong evidence that AMOC is weakening

Satellite observations provide some of the strongest evidence yet that the Atlantic Meridional Overturning Circulation is weakening. The AMOC carries heat across the Atlantic and influences weather, sea levels, and marine ecosystems. A continued slowdown could have wide-ranging climate impacts, though scientists still face uncertainties.
