| Restricting nuclear power has little effect on the cost of climate policies Posted: 01 Oct 2012 12:19 PM PDT By applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists analyzed trade-offs between nuclear and climate policies. Strong greenhouse-gas emissions reduction to mitigate global warming shows to have much larger impact on economics than nuclear policy, according to the study. |
| Chaos theory and a little physics predict the outcome at the roulette table Posted: 01 Oct 2012 08:06 AM PDT With enough information, physics can predict a great deal about the world around us, and that includes the fall of the ball in the game of roulette. |
| Posted: 01 Oct 2012 07:24 AM PDT Water does not forget, according to a chemist. Irrespective of what happens in the sea: whether the sun shines, algae bloom or a school of dolphins swims through a marine area -- everything and everyone leaves biomolecular tracks. With the help of a combination of new techniques, scientists can now identify and retrace some of these. |
| Nano-hillocks: Of mountains and craters Posted: 01 Oct 2012 06:58 AM PDT In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers were at last able to reconcile important issues concerning the effects of highly charged ions on surfaces. |
| Quantum physics: First images of Landau levels revealed Posted: 01 Oct 2012 06:54 AM PDT Physicists have directly imaged Landau Levels – the quantum levels that determine electron behavior in a strong magnetic field – for the first time since they were theoretically conceived of by Nobel prize winner Lev Landau in 1930. |
| Space travel with a new language in tow Posted: 01 Oct 2012 05:35 AM PDT Last Friday, for the first time ever, SES, the Luxembourg-based satellite operator, has allowed an Ariane 5 rocket to transport a TV satellite into space, which is made by Astrium and runs entirely on latest generation software. Every single one of the programs used to operate the satellite was written in the new satellite language SPELL. |
| A power grid that thinks for itself? Posted: 01 Oct 2012 05:35 AM PDT Most dishwashers are set to run around lunchtime and in the evenings, but is there a sufficient supply of electricity available from alternative energy sources at these peak times? Researchers are developing technologies for an intelligent power grid that provides a better balance between supply and demand. |
