The traditional Japanese art of folding paper is now adding grace and ease to the deployment of fragile solar panels, seismometers and other vital instruments in outer space.

Many young scientists dream of their first trip to a remote research site — who wouldn't want to hang out with chimps like Jane Goodall, or sail to the Galapagos like Charles Darwin, exploring the world and advancing science?

Bacteria like to clump together and cling to surfaces, where they secrete bits of molecular debris that grow into a slimy protective coating.

These gooey collections of bacteria are called biofilms, and they can be found everywhere — on moist rocks in streams, inside water treatment plants, and even on ...

Doctors regularly counsel expectant mothers about the risks associated with smoking, drinking and poor nutrition during pregnancy.
