- Humans and mice look and act very differently. But 85 to 90 percent of their genes are the same or quite similar. So an international group of scientists is deciphering the instructions in mouse genes to help us better understand our own.
- Sea levels have been rising for more than a century. But that rise is now speeding up. That suggests that what is driving the rise — climate change — also has increased dramatically in recent years.
- The sensors inside a boxy device measure the forces generated with each stroke of a bird’s wings. Learning how much force is needed to keep a bird aloft could help in designing future drones that flap, hover and dart.
- New research suggests a type of air pollution — diesel fumes — can affect your health. It inappropriately switches some genes on, while turning off others.
- About 5.25 trillion pieces of plastic float in the world's oceans, a new study finds. That's a problem. This 269,000 tons of plastic can choke, entangle and poison a wide variety of sea creatures.
- Air pollution from cars and industries can spew pollutants known as PAHs. A new study shows children have a greater risk of ADHD if their mothers inhaled a lot of PAHs while pregnant.
- Gut bacteria can play a powerful role in human health, new studies show. In one, bacteria turned a nutrient in red meat into a chemical that boosts the risk of a heart attack. Another study shows that our genes play a role in whether we are fat or thin, probably by affecting which bacteria prefer to live in our intestines.
- Previous research that suggested parenting affects a child’s IQ is flawed, researchers now conclude.
- This week, the presidents of China and the United States pledged to take aggressive action on the release of greenhouse gases to head off dire worldwide climate effects.
- Although biologists have observed fish playing before, scientists have now recorded hours of video showing a new type of antic in fish.
