  • Scientists built their own apparatus in a basement lab. It is an elaborate tangle of wires, computers, electrical components, tabletop mirrors, and a cryogenic refrigeration unit. "If you wanted to put a picture of something high-tech in the dictionary, this is what it might look like," Dave DeMille says. "It's deeply orderly, but with a bit of chaos." (Michael Helfenbein)

  • This undated photo provided by the National Park Service shows rocks that have moved across a dry lake bed in Death Valley National Park in California's Mojave Desert. For years scientists have theorized about how the large rocks —some weighing hundreds of pounds —zigzag across Racetrack Playa leaving long trails etched in the earth. Now two researchers at the Scripps Institution of Oceanography have photographed these "sailing rocks" being blown by light winds across the former lake bed. Cousins Richard Norris and James Norris say the movement is made possible when ice sheets that form after rare overnight rains melt in the rising sun, making the hard ground muddy and slick.

  • This July 28, 2014 photo shows Clive Pai, a University of Illinois, Chicago physical therapy professor, left, watching as researchers affix sensors to Mary Kaye, 81 before she demonstrates a treadmill balance session at the school in Chicago. Kaye, who is supported by a safety harness, walks on a lab-built walkway that causes people to unexpectedly trip and can teach them quickly how to catch themselves and avoid falling. Falls in the elderly cost $30 billion yearly to treat and can send them spiraling into poor health and disability. Pai who came up with the idea calls it "a vaccine against falls" and says his research shows that older people's brains can learn and adapt much more quickly than previously thought. (AP Photo/M.
