Caption: Many scientists today are finding that too much time spent indoors — at least during childhood — may affect vision, making it hard to see distant objects clearly. Doctors refer to this nearsightedness as myopia. Studies have found that kids who regularly spend time on computers have an increased risk of being diagnosed with myopia. Credit: iStockphoto

Scientists tweaked the genes of a bacterium so that it requires caffeine to live and reproduce. Now, they can use this microbe to measure concentrations of caffeine in beverages such as soda, coffee and energy drinks. When the microbes are added to a water-weakened version of one of those drinks, the bacteria grow and the liquid turns cloudy — but only if the drink contained caffeine. In caffeine-free Coke (top left), no cloudiness appears. Credit: Barrick Lab/University of Texas at Austin

This map shows the energy left over from shortly after the Big Bang, as mapped by the Planck space telescope. The average background temperature is about 2.7 degrees above the coldest possible temperature (known as absolute zero). Red spots are slightly warmer, while blue spots are slightly cooler. Astronomers hope this map can help them learn more about the history of the universe.
