A new study by Stanford researchers has added fuel to a debate about the differences between organic and conventionally grown foods. The Stanford report, an analysis of 237 studies of organic produce, meats and dairy foods, concluded that organic foods are no more nutritious than their conventional counterparts. Advocates of organic foods, meanwhile, say that…
The malaria species rampant in the Asia-Pacific region has been a significant driver of evolution of the human genome, a new study has shown.

As a teen growing up in Italy, Porfiri read Auster as well as Robert Musil,…
The most significant breakthrough in the laser pulse field in four years provides scientists with a new tool to watch quantum mechanics in action — a world hidden from view until now. The work was also accomplished without using specialized equipment, such as a mile-long particle accelerator or Superdome-sized synchrotron. University of Central Florida professor…
You already know it’s hard to balance your checkbook while simultaneously reflecting on your past. Now, investigators at the Stanford University School of Medicine — having done the equivalent of wire-tapping a hard-to-reach region of the brain — can tell us how this impasse arises. The researchers showed that groups of nerve cells in a…
Reliance on supernatural explanations for major life events, such as death and illness, often increases rather than declines with age, according to a new psychology study from The University of Texas at Austin. The study, published in a recent issue of Child Development, offers new insight into developmental learning. “As children assimilate cultural concepts into…
With the successful landing and deployment of the Mars Curiosity Rover, humanity has been treated to a sneak peek at the Red Planet for the first time. The possibility of establishing space colonies has been a scientists’ dream for decades, but working out a way to keep humans alive on the outside Earth’s protective shell…
