These parachutes unfurl thanks to Japanese paper-cutting techniques
Parachutes inspired by Japanese kirigami are full of holes. When dropped, they open automatically and fall more predictably than standard parachutes.

Scientists Say: Acceleration
Acceleration is a change in velocity. That could mean a change in speed or in direction.

Cool Jobs: Motion by the numbers
What do car crash testers, video game creators and scientists who study athletic performance have in common? All use geometry in their cool jobs.

Males and females respond to head hits differently
Men and women are playing sports equally — and getting concussions in comparable numbers. But how their brains respond may differ greatly.

Soccer: Watch out for collisions!
Scientists discover that concussions among high school soccer players stem more from aggressive contact between players than from heading the ball.

Magnets may make helmets safer
Magnets in sports helmets could repel players’ heads as they move toward a collision. This should reduce the risk of the hard hits that lead to concussions.

Lacrosse: Different genders, same injuries
Scientists find that boys’ and girls’ versions of lacrosse lead to similar injuries. Because girls frequently get concussions, the study argues that like the boys, girls too should wear helmets.

Football hits the brain hard
The brain’s hippocampus helps store memories. It is smaller in college football players — especially if they have suffered concussions.
