| Bright sparks shed new light on the dark matter riddle Posted: 01 Feb 2016 07:35 AM PST The origin of matter in the universe has puzzled physicists for generations. Today, we know that matter only accounts for 5 percent of our universe; another 25 percent is constituted of dark matter. And the remaining 70 percent is made up of dark energy. Dark matter itself represents an unsolved riddle. |
| Mechanical 'trees' swaying in the wind: Turning good vibrations into energy Posted: 01 Feb 2016 06:27 AM PST A project is testing whether high-tech objects that look a bit like artificial trees can generate renewable power when they are shaken by the wind -- or by the sway of a tall building, traffic on a bridge or even seismic activity. |
| Quirky cooling: The quantum fridge Posted: 01 Feb 2016 05:50 AM PST When cold milk is poured into a hot cup of tea, a temperature equilibrium is reached very quickly. The milk droplets and the tea particles interact, and after a few moments they all have the same average energy. This process is called thermalization. It plays a crucial role in cooling down gases to ultra-low temperatures. But surprisingly, even gases for which this effect is suppressed can be cooled. Scientists took a closer look at this phenomenon and found a special quantum-mechanical kind of cooling at work. |
| Unprecedented: Expedition recovers mantle rocks with signs of life Posted: 01 Feb 2016 05:44 AM PST An international team of scientists -- recently returned from a 47-day research expedition to the mid-Atlantic -- have collected an unprecedented sequence of rock samples from the shallow mantle of the ocean crust that bear signs of life, unique carbon cycling, and ocean crust movement. These unique samples were collected using unique seabed rock drills. |
