This cosmologist studies the invisible parts of the universe

Katie Mack started out building solar-powered LEGO cars as a kid. Now she studies dark matter to better understand how galaxies form and evolve.

Science & Society

Linking science to dance, culture and more expands who can take part

Through movement, sound, culture and community, some researchers are expanding the ways we learn, think about and communicate science and engineering.

Physics

Chopping an onion? Sharp knives can keep its juice out of your eyes

Slow and steady cuts with a sharp blade, video shows, can reduce the pain-inducing spray of tiny onion-juice droplets by more than 100 feet!

Animals

Some Antarctic fish arrange their nests into odd shapes

Moss spores, bacteria and tardigrades have all proved their hardiness outside the International Space Station.

Math

Scientists Say: Logarithm

Think of this math function as just another way to solve equations involving exponents.

Chemistry

Scientists finally know why ice is so slippery

It’s not because ice heats up and then partially melts. Rather, ice changes at the molecular level — a process scientists have finally modeled.

Fossils

Newfound fossil is not a teen T. rex but a whole new species

Now known as Nanotyrannus, this mini dino could have roamed the late Cretaceous alongside T. rex.

Brain

Hypnosis isn’t magic. It’s the brain at work

While we still don’t know much about how hypnosis works, it appears to help some people conquer pain, anxiety and other problems.

Health & Medicine

Air pollution might harm children’s eye health

Scientists used machine learning to understand air pollution’s role in eye health and vision. They found children have better eyesight in cleaner air conditions.

Animals

Woodpeckers grunt like tennis players when they peck

The birds grunt like tennis pros when making their rat-a-tat, a strategy that may help steady their movements.

Psychology

Sometimes the best way to reach a goal may be to quit an old one

We’re surrounded by messages to persevere through all challenges. But science shows that knowing when — and how — to quit is important, too.
