Cannabis is often used as a sleep aid, but does feeling well rested tell the whole story? Drawing on nearly 35 years of data, researchers compared cannabis use with sleep monitoring and participants’ own assessments, raising questions about a widely held belief.

An unusually well-preserved snake fossil from Brazil is adding a new dimension to the debate over how snakes evolved. Hidden within its 80-million-year-old skull, researchers have uncovered clues to how the animal lived and sensed its surroundings.

Why do large dogs tend to live shorter lives? A study of 864 dogs links body size to faster loss of DNA methylation at regions containing “jumping genes”. The findings offer a possible molecular explanation for differences in canine ageing, although whether these changes help drive ageing remains unclear.

A UC Berkeley researcher co-authored a study that raises profound questions about how we interact with artificial intelligence in education — and daily life.

A fluorine-free, water-processable binder could simplify lithium-ion battery manufacturing and recycling. Developed at the University of California San Diego, it allows electrode coatings to separate from metal foils in water, while laboratory tests showed comparable initial battery performance and improved capacity retention.
