Materials found in dust, including common fats, may trigger human fat cells to grow. This might promote weight gain, some scientists worry.
Ancestral humans and their extinct relatives had much more DNA than do people today, a new study finds. It mapped genetic differences over time among 125 different human groups.
Roosters know their places in the chicken world. Lower-ranking birds defer to the guy at the top of the pecking order. And they show it by holding their crows until after he greets the new day.
This glossary provides definitions and audio clips to help you learn and pronounce even the toughest science terms.
This step-by-step series from the Eureka! Lab blog explains how anyone can do a research project and do it right.
A study in L.A. high school students finds that those who vape are much more likely than those who don’t to eventually take up smoking cigarettes.
The newly uncovered 400-year-old remains of four leaders of the Jamestown settlement in Virginia reveal details of the notable’s lives — and deaths.
Both e-cigarettes and tobacco products can release large amounts of nicotine during use. Nicotine is the chemical that makes tobacco addictive — and the teen brain is especially vulnerable to it.
One of the largest sky surveys ever made has found that the universe is in decline. And after losing even more energy over the next 100 billion years, it will be dark, empty and boring.
Hands-on instruction by trial and error is gaining traction. Kids really can learn mightily from their mistakes.
Watering farmlands in arid parts of the world could have long-term climate benefits, a new study concludes.
Eager to test new sensors before the next ‘big one,’ earthquake scientists make use of a predictable source of ground-shaking: football fans.
Physicists have finally caught a brief glimpse of massless subatomic particles that were first predicted to exist 85 years ago. It’s the elusive Weyl fermion.
Scientists have found a few teeth and a fossil jaw of an ancient species of primate. It may be related to modern lemurs or tarsiers.
The current El Niño event could be a record breaker, changing weather patterns worldwide and bringing rain to drought-parched California.
These parasites can be scary, but they rarely trigger infections. Still, knowing more about them can help you avoid behaviors that heighten risks.
The human fetus is prepared to develop as a female. But if its chromosomes or other chemical signals instruct it to become male, then gene pathways will flip some chemical switches to create masculine organs and features.
Due to global warming, bumblebees are disappearing from their southernmost homes. But their northern borders are expanding to compensate. This leaves the insects with less territory.
Scientists discover that concussions among high school soccer players stem more from aggressive contact between players than from heading the ball.
Some animals behave as if they were the opposite sex; others can even change their sex — and still produce offspring.
Certain medical conditions demonstrate how complicated biology can be. Being genetically male and female will not guarantee that your body won’t sometimes contain one or more features of both.
Not all ancient reptiles were dinosaurs. Some soared, many swam the seas and still others looked like dinos—but actually weren’t.
No known dinosaurs lived in the oceans. But there were lots of big aquatic reptiles that were every bit as ferocious and awesome.
Manufacturing indigo to dye blue jeans now relies on harmful chemicals. But researchers have found a less polluting way to produce the blue tint: bacteria.

Don’t jump to conclusions from statistics unless you understand correlation, causation, coincidence and confounding factors.
Scientists discovered the molecular tool that roses use to make fragrance. And it wasn’t what they expected.
A new study finds that kids with autism sniff foul scents for as long as pleasing ones. The finding could lead to a test to diagnose the disorder.
The light from stellar fireworks in a galaxy far, far away has just reached Earth. It comes from a star that exploded in a massively bright flash.
