Danish scientists find that very overweight kids grow up with a heightened risk of colon cancer and stroke.
Jupiter is covered in swirling storms. A new 3-D map of the planet’s atmosphere shows those storms start far, far below the clouds.
Fertilizer runoff can fuel the growth of toxic algae nearby lakes. A teen decided to harness a tiny plant to sop up that fertilizer.
Splitting Erwin Schrödinger’s famous — and fictitious — cat between two boxes brings scientists one step closer to building quantum computers from microwaves.
Scientists zapped ice crystals in a lab. They were exploring whether this approach might be used to break those crystals in clouds — potentially as a way to cool Earth’s fever.
Molecular biologist and astronaut Kate Rubins has spent 7 years preparing for a mission to the International Space Station. She blasts off this month.
Nihonium? Tennessine? These aren’t body parts or medicines. They’re among the names just given to the four newest superheavy elements.
Neandertals built stalagmite circles in a French cave 176,500 years ago. These structures show that these ancient human cousins had social and technical skills.
A disease is wiping out amphibian species around the globe. New research shows how some frogs develop immunity.
The massive black hole in the movie Interstellar would create a unique gravity-wave signal when gobbling a smaller partner.
An Irish teen has invented a device that helps people with multiple sclerosis address the “clenched fist” symptom that afflicts most such patients.
Electric eels are fascinating animals. Their powerful zaps can act like a radar system, trick fish into revealing their location and then freeze their prey’s movements.
Given a choice, baby fish will eat plastic microbeads instead of real food. That plastic stunts their growth and makes them easier prey for predators.
A Swedish teen’s analyses of a sample of amber may have uncovered a previously unknown type of ancient tree.
After slurping up harmful algae, copepods swim fast and straight — making them easy prey for hungry predators.
Scientists worry that increasing temperatures could combine with air pollution to up rates of illness and premature death — perhaps dramatically.
Many of the world’s lushest tropical forests would starve if winds didn’t bring them nutrient-rich dust from across an ocean.
Many government programs urge people to save electricity by using more efficient TVs. Here’s why these programs should target “couch potatoes.”

It can reproduce plastic models of the precise faulty vessels that need fixing. Now doctors can see them, hold them and practice on them long before they pick up a scalpel.
A detailed new map shows that people comprehend words by using regions across the brain, not just in one dedicated language center.
Vast rivers of dust flow through the sky. This invisible force shapes our world in profound ways. And scientists are finally homing in on a major source.
A teen discovered that extracts from leaves of the San Francisco plant (Codiaeum variegatum) kill larvae of the mosquito that helps spread the Zika and dengue fever viruses.
Dolphins produce clicking noises that bounce off of prey, like sonar, showing where they are. Mucus in the animals’ nasal passages may make that ‘sonar’ work.
Bed bugs change their color preferences as they get older. Adults like red and black, which may help the dark bugs avoid predators.
A new technique can help engineers figure out where a bird or other object collided with a wind turbine or other whirling blade.
