Studying Molecules that Regulate the Body???s Circadian Rhythms
Apr 30, 2013
Most often, people associate circadian rhythms with the symptoms of jet lag that occur after crossing several time zones. Circadian rhythms, which get their cues from light and darkness, can change sleep-wake cycles, hormone secretion, body temperature and other bodily functions.

Fabricating the Future: 3-D Printing Molds New K-12 STEM Model
Apr 26, 2013
Driven by design software, 3-D printers churn out made-to-order objects on a desktop. A myriad of materials from polymers to metal alloys enable virtually anyone to manufacture almost anything they can imagine, including glow-in-the-dark pens, Lego-like building blocks, cogs and gears, electrical circuits and jewelry. Advanced applications produce living tissue for replacement organs in the body, intricate engine designs and parts for spacecraft during deep space missions.

See Saturn at its Best and Brightest
Apr 25, 2013
The Solar System is a beautiful place filled with wonders that NASA space probes are only beginning to discover. There's a tendency, though, for people to become indifferent; every year Hubble, Cassini, MESSENGER and other spacecraft beam back gigabytes of jaw-dropping images. After a while, you don't have any more "gasps" left in you.

Energy Efficient Brain Simulator Outperforms Supercomputers
Apr 24, 2013
In November 2012, IBM announced that it had used the Blue Gene/Q Sequoia supercomputer to achieve an unprecedented simulation of more than 530 billion neurons. The Blue Gene/Q Sequoia accomplished this feat thanks to its blazing fast speed; it clocks in at over 16 quadrillion calculations per second. In fact, it currently ranks as the second-fastest supercomputer in the world.
