For almost half a century, scientists have struggled with
plutonium contamination spreading further in groundwater than expected,
increasing the risk of sickness in humans and animals.
It was known...

Astronomers have made the best determination of the power of
a supernova explosion long after it was visible from Earth. This technique,
using X-ray and optical observations, may help reveal the details of how some
stars...

If the Flintstones had electricity, their wires might have
been made of rock. New results in Science Express show that a chunk of hematite
can conduct electrons under certain chemical conditions. In addition, the
current...

For the first time, physicists have devised a
way to make visible light travel in the opposite direction that it normally
bends when passing from one material to another, like from air through water or
glass. The phenomenon is known as...
