A team led by a Purdue University researcher has achieved images of a virus in detail two times greater than had previously been achieved.

University of Arizona optical scientists have broken a technological barrier by making three-dimensional holographic displays that can be erased and rewritten in a matter of minutes.

When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions.

Researchers examined the ultrafast movement of electrons in a gallium arsenide crystal exposed for a short time to a very high electrical field.

Harry Potter may not have talked much about plasmonics in J. K. Rowling's fantasy series, but researchers are using this emerging technology to develop an invisibility cloak that exists beyond the world of bespectacled teenage wizards.

U.S. troops blew up enemy bridges with explosives in World War II to slow the advance of supplies or enemy forces.

The colors of the sunset result from a phenomenon called scattering, says Steven Ackerman, professor of meteorology at UW-Madison. Molecules and small particles in the atmosphere change the direction of light rays, causing them to scatter.

Scientists at the University of Virginia have discovered a new class of hydrogen storage materials that could make the storage and transportation of energy much more efficient and affordable through higher-performing hydrogen fuel cells.

Using an existing technique in a novel way, Cornell physicist Keith Schwab and colleagues at Cornell and Boston University have made the scanning tunneling microscope (STM) -- which can image individual atoms on a surface -- at least 100 times faster.

A single solar cell produces a relatively low output – it’s a case of strength in numbers. Tiny strips of metal are used to link cells together. If the laser soldering temperature is too high, the solder joint may fracture. A new system provides autom
