Eating red meat can increase the risk of certain types of cancer. But scientists have discovered that eating potatoes and other foods containing 'resistant' starch can help limit those risks.
A number of diseases threaten the world’s most popular fruit. Scientists are working to fight these blights. But if they don’t succeed, the sweet banana that’s a breakfast staple could disappear.
Classroom questions for Saving the banana.
Molecular traps have been developed to snag and hold noble gases, such as krypton, xenon and radon. These atoms tend to resist arrest. But the new traps might grab onto polluting gases so that they can be recycled for later beneficial uses.
The Democratic Republic of Congo (formerly Zaire) is where the Ebola virus was first discovered in 1976. This nation has just been hit again by the disease. Scientists suspect this is a new and independent outbreak — not a spread of the epidemic ravaging West Africa.
Any of nearly 1,500 asteroids could hit Earth. Experts want to learn more about the space rocks — and maybe even bump them off course.
Leftovers from the creation of the solar system, asteroids are space rocks that orbit the sun. Let’s hope the big ones never become meteorites.
Classroom questions for Asteroids: Avoiding an Earthly smashup.
Hidden images make a new label virtually counterfeit-proof, thanks to a combination of chemistry and nanotechnology.
Using experimental medicines against Ebola might help to slow or end an outbreak in Africa that has defied efforts to control it.
A virus is behind the hemorrhage-inducing infection called Ebola. It causes fevers and often intense bleeding — seemingly from anywhere and everywhere.
A dino discovery in Siberia suggests feathers were common among the ancient ‘lizards.’
Last year, scientists drilled 800 meters (roughly a half mile) down through ice to reach a pitch-black Antarctic lake. They now report that lake hosts a thriving community of one-celled microbes.
A handshake, while welcoming, can transmit lots of germs — many times more than a high five or, especially, a fist bump.
The bacteria that people and other animals host in and on their bodies are invisible to the eye. Yet they can play a very visible role in behavior. It’s something scientists are just coming to appreciate.
Science and social studies questions on "Germs explain some animal behaviors."
Scientists have tracked harbor seals visiting the turbines of ocean wind farms. The predators may be drawn by fish that make their homes in the artificial reefs created by the manmade structures.
Enormous meteorites appear to have slammed into Earth several times early in its history. Each mega-smashup would have boiled off oceans and obliterated any bit of life.
When danger comes too close, termites bang their heads against the walls of their homes. This action sends out a warning vibration that others ‘hear’ with their legs.
Recycled waste water may slake the thirst of outdoor plants. But it also can spread bacteria, a new study finds — germs that antibiotics may not be able to kill.
