Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that should lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops.

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis.

Tiny LEDs built into lenses will project images in front of users wearing the lenses, allowing them to see labels and text, as Arnold Schwarzenegger did in the Terminator movies.

New data from Chinese-Danish collaboration shows that organic nanoscale wires could be an alternative to silicon in computer chips.

Painless patch may someday render hypodermic needles, as well as annual flu shots, a thing of the past.

Using tiny crystals called quantum dots, Johns Hopkins researchers have developed a highly sensitive test to look for DNA attachments that often are early warning signs of cancer.

You probably have cocaine in your wallet, purse, or pocket. Sound unlikely or outrageous? Think again! In what researchers describe as the largest, most comprehensive analysis to date of cocaine contamination in banknotes.

Bacterial infection is a major health threat to patients with severe burns and other kinds of serious wounds such as traumatic bone fractures. Recent studies have identified an important new weapon for fighting infection and healing wounds.

Research at the University of Liverpool has shown it is possible to develop an 'invisibility cloak' to protect buildings from earthquakes.

New design grows optically active semiconductors in arrays of nanoscale pillars, each a single crystal, with dimensions measured in billionths of a meter.
