Global warming - 56 million years ago
(01/23/2013) Sandy, Irene, Katrina... Hurricanes are fast becoming household names and have many people worried over the connection between extreme weather and the amount of greenhouse gases people are pumping into the atmosphere. No one can predict for sure what will happen decades or centuries from now as such gas concentrations increase. But scientists have a pretty good picture of what did happen in the past; greenhouses gases were released into the atmosphere in massive amounts at least once before—around 56 million years ago.
Soccer lights up kids' lives: new technology produces cheap, portable power
(07/16/2012) Recently, Jessica O. Matthews and Julia Silverman, both Harvard graduates, were awarded Harvard Foundation’s Scientists of the Year award for their invention of a soccer ball that converts kinetic energy to electricity. The two women, who were both social science majors, came up with the idea when they were taking an engineering class for non-majors and were required to create a project that would address a social problem.
Solar cells cross new threshold
(03/08/2012) Imagine powering your cell phone by leaving it on the window sill. Sounds like science fiction? Actually, this might soon turn into reality. Scientists have been exploring the potential of solar energy for decades. One of the cheapest ways to turn solar energy into electricity is by creating solar cells from organic polymers, which are easily manipulated by scientists. However, such cells are not efficient at converting sunlight to electricity. But now, researchers at UCLA’s Department of Materials Science and Engineering have come up with a new type of solar cell that sets the record in changing sunlight into power.
