For millennia, humans have harnessed the power of clocks to schedule prayers, guide ocean voyages and, lately, to chart the universe.
Science News writers report on the latest scientific investigations into time’s place in the physical, biological and mental worlds.
The Venus Express orbiter detected possible signs of active volcanism on the planet next door.
A new study pinpoints the part of the brain that controls the neck muscles, tweaking the motor homunculus.
Brains crumple up just like wads of paper, a new study suggests.
