In some ways, machine vision is superior to human vision. In other ways, it may never catch up.
Origin-of-life researchers have usually studied the potential of pure starting materials, but messy mixtures of chemicals may kick-start life more effectively.
A giant star’s death throes may offer the first evidence of a pair-instability supernova, and a glimpse of the first stars in the universe.
A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.
Clues from fish diversity suggest that interbreeding between species could be a major mechanism of fast speciation.
