"In God We Trust" (At least until the government gets its act together)

One of the more predictable outcomes of a government shutdown --in fact, the hyperbolic chatter alone regarding the uncertainties of such a major disruption is enough to do the trick--is that there will be a noticeable surge in the nation’s religious beliefs. According to Duke University psychologist Aaron Kay and his colleagues, God and government are more than just two sides of the same US-issued coin. In fact, they share a common cognitive denominator.

New hope for preventing pre-term births

It’s one of the great frustrations of obstetric medicine: humans have been reproducing for hundreds of thousands of years, and yet doctors still haven't unraveled the mystery of why some women give birth well before their babies have fully developed in the womb. Despite researchers' and physicians' best efforts, the rate of preterm births--defined as babies born before 37 weeks of gestation--climbed 30 percent from 1981 through 2006.

Absolute Hero: Heilke Onnes’s Discovery of Superconductors Turns 100 [Slide Show]

On April 8, 1911, at the Leiden Cryogenic Laboratory in the Netherlands, Heike Kamerlingh Onnes and his collaborators immersed a mercury capillary in liquid helium and saw the mercury's electrical resistance drop to nothing once the temperature reached about 3 kelvins, or 3 degrees above absolute zero (around –270 Celsius). This phenomenon of "superconductivity" was one of the first quantum phenomena to be discovered, although back then quantum theory did not exist. In subsequent decades theoreticians were able to put quantum physics on a solid foundation and explain superconductivity.
