Scientists Say: Extremophile
Some species can survive high heat, freezing cold or other extreme environments. Scientists call these organisms extremophiles.

New rules point scientists toward next-gen germ-killers
Shape and other features help germ-killing drugs make it through barriers to enter bacteria. Knowing how they do this could lead to more and better better antibiotics.
- Fossils
Study claims to have found oldest human fossils
Humans, as a species, may be much older than previously thought. They also may have evolved further North and West of the suspected cradle of human evolution.

Underwater robot vacuums up lionfish
Lionfish damage coral reefs in the Atlantic Ocean. A new underwater robot hunts, stuns and captures the bullies with help from a human operator.
- Genetics
Scientists Say: Chromosome
This threadlike structure is made of DNA wrapped around protein. It allows the 3 billion base pairs in human DNA to stay neatly packaged in a cell.

Plant extract mutes germs to fight infections
A plant extract prevents the aggressive behavior seen in some germs. Using it could fight the development of most bladder infections, a teen’s research suggests.

When is an epileptic seizure about to strike?
Two high-school research projects suggest ways to identify early warnings of a coming epileptic seizure. This might give people time to free themselves from potentially dangerous activities.

How the house mouse found its home
Once people started settling down 15,000 years ago, a mouse species followed them indoors. The animals didn’t need people to be farming and storing food.

A light-filled box could blast bacteria from lab coats
Doctors can pick up bacteria on their lab coats. A teen has designed a special light-filled box to keep those coats from infecting others with those germs.
