Traditional color printing -- whether done with an inkjet, laser or silkscreen -- requires a page to be laid out with several different inks in various colors to produce a full color image. But Korean engineers have developed a different process using a single nanoparticle-imbued ink, which could produce color prints in fractions of a second.

Whoever thinks science isn't fun must have never heard of Legos. The colorful construction toy has been used before as a cellular teaching tool. But these days, even researchers working in the nanoscale world get to play around a little.

The retina is a lush layered field of tissue lining the back of the eye, a complex mix of specialized cells that serve as a transfer station where light signals are absorbed and sent to the brain to be translated into sight.

Researchers from University of Wisconsin, Madison have now created these unique retina cells from lowly skin cells -- opening the possibility that patients with damaged or diseased retinas might some day be able to grow themselves a cure from their own skin.

Human activity has widely affected our planet, reshaping surfaces, moving or extinguishing species, and warming the air and water. Now scientists say our reach has been extended even further -- warming oceans may even start to shift the Earth's axis of rotation.

For all the visualizations, artist's renderings and animations of the birth of our universe, it is still exceedingly hard to imagine the Big Bang: from nothing emerges everything.

But what if you could create a big bang on a lab bench -- make a model of the universe's emergence. University of Maryland engineering professor Igor Smolyaninov has proposed just that, describing the opportunity to create a "toy big bang" using precisely designed metamaterials that are mathematically analogous to certain conditions of the real-world big bang.

As tonight bleeds into tomorrow morning, the earth will be hurtling through a long skein of dust and rocks. Lucky for us, the result of our bombardment will not be annihilation, but rather one of the richest natural light shows of the year—the Perseid meteor shower. Here's how to watch.

The first American to be implanted with a wireless pacemaker is now walking happily around while the device communicates remotely with her doctor.

Carol Kasyjanski of New York became the first patient to receive the new pacemaker, which was made by St. Jude Medical Inc. and approved by the FDA in July. The device downloads all its information into a remote monitor in Kasyjanski's home at least once a day and the monitor automatically assesses the performance of both the pacemaker and the patient’s heart. Then it uploads the information to a central server.

You can already swing a metaphorical tennis racket, do the virtual hula or drive a virtual steering wheel. So what could possibly be next for the Wii?

Why, this inflatable horseback riding saddle controller, of course. Seriously—-a saddle. To ride in your living room.
