Squeezing light into metals

Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Human hands 'designed to throw punches'

Opposable thumbs: one of the features that separates us from other apes, a contributor to the tool use that's made us the dominant species on the planet. Makes you feel quite smug, right? Well, not so fast.

Grandmothers responsible for human longevity

The helpfulness of grandmothers is the reason humans don't die in their thirties the way chimpanzees do, new research shows - and may even explain our bigger brains.

Winds high in stratosphere affect deep ocean currents

Evidence has emerged that changes in the winds high up in the stratosphere have a powerful effect on ocean currents a mile below the surface.

Spintronic LED is brighter and cheaper

A new 'spintronic' organic light-emitting diode promises to be brighter, lower-cost and more environmentally friendly than those currently used in lighting, television and computer displays and other electronic devices.

Sexting common amongst US teens

Sending and receiving sexually explicit cellphone photos, or sexting, is widespread amongst US teenagers, a new study has found.

New game controller tugs on players' thumb tips

University of Utah engineers have designed a new kind of video game controller that gives players the sensation of the tug of a fishing line, the recoil of a gun or the feeling of ocean waves.

Researchers find new way to purify water

University of Utah researchers have developed a new way to purify water: zap microbes with electricity until they do the job for you.

World's tiniest memory created in atomic nuclei

University of Utah physicists have stored information for 112 seconds in atomic nuclei and then been able to read it back.

Software edits huge images in seconds instead of hours

University of Utah computer scientists have developed software that edits gigapixel images in seconds to produce preview images useful to doctors, intelligence analysts, photographers, artists, engineers and others.

New technique could allow the paralyzed to 'speak'

University of Utah scientists have demonstrated that planting microelectrodes on the surface of the brain can allow people to 'speak' with their thoughts.

Lie detector works by targeting people with 'shifty eyes'

It might come as a surprise to daytime TV viewers - "We've proved your husband was cheating!" - but polygraphs aren't actually that accurate.
