Energy storage advance readies concentrated solar power for the smart grid

Concentrated solar thermal power plants, such as this one in the California Mojave Desert, could soon ...

The intermittent nature of renewable energy sources is a huge burden on the power grid, making flexible and economical energy storage an essential step to a greener future. Researchers at Oregon State University (OSU) and the University of Florida have now devised a way to conveniently store and release energy harvested through concentrated solar power (CSP) plants, improving on the cost and energy density of previous systems and preparing this technology for the smart grid.

Secret to jellyfish propulsion could be applied to human tech

A jellyfish used in the propulsion experiments

Until now, scientists weren’t entirely sure how marine life like jellyfish and eels are able to move so effortlessly from point A to point B, using less energy than it takes any other moving life form ever measured. But researchers at the University of South Florida (USF) believe they may have now found the answer. Rather than propel themselves forward by pushing against the water, jellyfish and eels actually suck the water toward them.

First observations made with deep-space water-hunting instrument

SEPIA was installed on APEX earlier this year

A team of astronomers has made the first observations with a cutting-edge water-hunting instrument. The instrument, known as the Swedish–ESO PI receiver for APEX (SEPIA), is not only suited for identifying signatures of water and other molecules in the Milky Way but also in other galaxies, and it may even be capable of detecting ancient water dating back to the early Universe.
