By adding nanoparticles made of pure gold and silver to fine Marino wool, researchers in New Zealand have created a rainbow of unexpected colors intended for high-end, couture fashion designers. They unveiled the first scarf dyed with gold nanoparticles….

Spherical gold nanoparticles about 10 nanometers across create a red wine color. As their size increases to 100 nanometers, the color turns red, then purple, blue, and finishes off in various shades of gray.

News that scientists have for the first time genetically altered a human embryo is drawing fire from some watchdog groups that say it’s a step toward creating “designer babies.”

The idea of designer babies is that someday, scientists may insert particular genes into embryos to produce babies with desired traits like intelligence or athletic ability. Some people find that notion repugnant, saying it turns children into…

Many of Egypt’s most famous monuments, such as the Sphinx and Cheops, contain hundreds of thousands of marine fossils, most of which are fully intact and preserved in the walls of the structures, according to a new study.

The analysis determined the primary building materials were “pinky” granites, black and white granites, sandstones and various types of limestones. The latter was found to contain “numerous shell fossils of nummulites gen.” At…

On last week’s episode of “South Park,” residents of our favorite made-up mountain hamlet woke up to a new kind of horror: a townwide Internet outage. No e-mail, no WebMD.com to check rogue symptoms and, most harrowing of all, no Internet porn. Panic-stricken and Net-starved, Stan Marsh and his family lash their belongings to the roof of their SUV

"South Park" has the Internet in its very DNA. Grainy videotapes of the show's 1995 prototype, "The Spirit of Christmas," which featured a vicious (and, back then, blasphemous) duel between Santa and…

A subtle and previously unknown global vibration has been found at Earth’s quietest seismic stations. The hippies were right all along!

The Love wave is a mode that essentially torques the Earth's north and south hemispheres against each other. It's as if the planet is dancing the Twist, explained Rudolf Widmer-Schnidrig of the Black Forest Observatory in Wolfach,…

No matter how much you like your crewmates, a three-year mission to Mars would test the even the best of relationships…

“Sixty percent of people in war are dead right there on the field,” Zapol said. “They are instantly hurt, and because there is no blood and no fluids in the field, by the time they get to a hospital they are cold and dead and there…

Materials scientists go window-shopping for the latest devices. Look at the stuff they’re looking at to look at stuff at the minutest scale.

Nanotech tool vendors hawked their wares to innovative engineers at the spring meeting of the Materials Research Society this week at San Francisco's Moscone Center. We took a break from presentations on molecular motors and the mechanical…

Scientists from three universities recently hacked into an implantable biomedical device through a wireless connection, stole information about a hypothetical patient’s health and personal history and changed the cardiac defibrillator’s settings.

March 27, 2008 — Scientists from three universities recently hacked into an implantable biomedical device through a wireless connection, stole information about a hypothetical patient's health and personal history and changed the…

It may not look like much, but a slippery, Jello-like material developed by scientists in the United States and Japan could soon be improving everything from artificial joints to contact lenses.

Produced from materials that are cheap and readily available, the hydrogel is held together by two polymers. The first is a charged solid that clings to a second, uncharged liquid polymer. If a crack develops in the solid polymer, the liquid…
