Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed
to electronic circuits and strength to materials like carbon composites, used in
airplanes and racecars. A major problem, however, is that the metals used to
grow...

Folding paper into shapes such as a crane or a butterfly is challenging
enough for most people. Now imagine trying to fold something that's about a
hundred times thinner than a human hair and then putting it to use as an
electronic device....

For the first time, MIT researchers have shown they can genetically engineer
viruses to build both the positively and negatively charged ends of a
lithium-ion battery.
The new virus-produced batteries have the same energy capacity and...

Ever since the 1940s, chrome has been used to add a protective coating and
shiny luster to a wide range of metal products, from bathroom fixtures to car
bumpers.
Chrome adds beauty and durability, but those features come at a heavy...

Researchers are reporting compelling new scientific evidence for the
existence of low-energy nuclear reactions (LENR), the process once called "cold
fusion" that may promise a new source of energy. One group of scientists, for...
