The thermodynamics of computing

Information processing requires a lot of energy. Energy-saving computer systems could make computing more efficient, but the efficiency of these systems can't be increased indefinitely, as ETH physicists show.

Scientists create 'Swiss army knife' for electron beams

DESY scientists have created a miniature particle accelerator for electrons that can perform four different functions at the push of a button. The experimental device is driven by a terahertz radiation source and can accelerate, ...

27 of Einstein's personal letters going on auction block

When he wasn't busy scribbling out the theory of relativity, Albert Einstein seems to have spent a fair amount of time writing letters involving topics such as God, his son's geometry studies, even a little toy steam engine ...

New solarclave uses nanoparticles to create steam

(Phys.org) —A team of researchers at Rice University has developed a solar powered autoclave based on solar energy and metal and carbon nanoparticles. In their paper published in the journal Proceedings of the National ...

Medieval water power initiated the collapse of salmon stocks

Salmon largely disappeared from the Netherlands due to the construction of water mills, ecologists from Radboud University conclude (Scientific Reports, 20 July). The construction of water mills caused the destruction of ...

Efficiency record of combined cycle power plant

A new Siemens gas turbine operated in a combined cycle with a steam turbine in Irsching, Bavaria, has set a world record for efficiency, making it an outstanding example of green technology. The net efficiency of 60.75 percent ...
