Green Microchips Are Faster

Researcher at Rice University, Krishna Palem has found that "pruning" away the little-used circuits on microchips can double the energy efficiency and computing speed of the chips.

Microchips installed in multimedia devices like hearing aids and cameras can be made more efficient and much faster by trimming off unnecessary portions of the circuitry. Accuracy in the devices, however, is reduced. "The result of this less-accurate computing process is much greater efficiency. By cleverly managing the probability of errors and by limiting which calculations produce errors, the designers have found they can simultaneously cut energy demands and boost performance."

Five foods that increase your psychological well-being

These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.

Mind & Brain

We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.

For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
