| Weak charge of proton determined for first time Posted: 17 Sep 2013 12:37 PM PDT Researchers have made the first experimental determination of the weak charge of the proton. The results also include the determinations of the weak charge of the neutron, and of the up quark and down quark.  |
| Researchers study ways to make stronger materials in 3-D Posted: 17 Sep 2013 12:37 PM PDT Using methods similar to 3-D printing, researchers are running computer simulations of processes that could lead to stronger, more durable materials for the space agency.  |
| Clean energy least costly to power America's electricity needs Posted: 17 Sep 2013 09:48 AM PDT Findings show carbon pollution from power plants can be cut cost-effectively by using wind, solar and natural gas. It's less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study.  |
| Energy from tides and currents: Best arrangement of tidal sails device determined Posted: 17 Sep 2013 09:36 AM PDT In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race -- the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water.  |
| Smartphone 'microscope' can detect a single virus, nanoparticles Posted: 17 Sep 2013 06:39 AM PDT Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. An engineer has created a portable smartphone attachment to enable sophisticated field testing of fluid and solid samples for detection of viruses and bacteria without need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.  |
