In recent years, scientists have discovered that 95 percent of the contents of the cosmos are invisible to our current methods of direct detection. Yet something is holding galaxies and galaxy clusters together, and something else is causing space to fly apart. Scientists call these invisible components dark matter and dark energy: "dark" because these phenomena do not emit light. Dark...

"The latest research shows that people almost never "rise to the occasion" when faced with a life-threatening challenge, regardless of how often we hear that phrase. Instead, as Professor Nancy Zarse explains in the 12 empowering lectures of Survival Mentality: The Psychology of Staying Alive, people generally revert to their lowest level of training and preparation. And Professor Zarse knows this firsthand. She brings not only her academic knowledge,...
