- A new scent-delivery system ensures that the more you sweat, the more perfume it releases. In fact, it only works in contact with moisture.
- A new study suggests deep-water fish may have health problems linked to human pollution. Eating these fish may expose diners to the same pollution.
- 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.
