Physicists Take Their Closest Look Yet at an Antimatter Atom

Scientists at CERN found a way to trap hydrogen’s mirror twin, antihydrogen, long enough to study it in greater detail than ever before.

What If ‘Planetary Alignment’ Really Could Make Brooms Balance?

Celestial bodies aren't the reason broomsticks can stand up on end. If they were, it would unleash gravitational chaos.

Cheap Nanoparticles Pave the Way for Carbon-Neutral Fuel

A new way to produce nanoparticles—which convert carbon dioxide emissions into fuel—may help a niche green-energy technology go mainstream.

Thirty-four Meuse-Rhine-Issels aboard a stable in Rotterdam harbor show that cow buoys could provide a creative way to boost food security.

A Car ‘Splatometer’ Study Finds Huge Insect Die-Off

Measuring how many bugs fly into car windshields might sound silly. But to scientists predicting an “insect apocalypse,” the numbers are deadly serious. 

Psychedelic Fiber Offers a New Twist on the Science of Knots 

A stretchy plastic that changes colors as it deforms lets mathematicians and physicists model the stress points of knots, and test which is the strongest. 

'Baby Talk' Can Help Kids Learn Language (Oh Yes It Can!)

The more ‘parentese’ there is at home, the more likely a child is to have an advanced vocabulary later on.
