Nano-engineering electrodes to give tiny generators a boost

Could our waste be part of the answer to humanity's energy problems? Some researchers think so, thanks to bacteria that chow down on everything from sewage to heavy metals and give off electricity as one of their own waste ...

New technique grows tiny 'hairy' materials at the microscale

(Phys.org) —Scientists at the U.S. Department of Energy's Argonne National Laboratory attacked a tangled problem by developing a new technique to grow tiny "hairy" materials that assemble themselves at the microscale.

Seal takes ocean heat transport data to new depths

The Antarctic Circumpolar Current flows in a loop around Antarctica, connecting the Atlantic, Pacific and Indian oceans. It is one of the most significant ocean currents in our climate system because it facilitates the exchange ...

NASA rover prototype set to explore Greenland ice sheet

(Phys.org) —NASA's newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle ...

Microbes in the seafloor: Little nutrients, lots of oxygen

About one quarter of the global seafloor is extremely nutrient poor. Contrary to previous assumptions, it contains oxygen not just in the thin surface layer, but also throughout its entire thickness. The underlying basement ...

Flow phenomena on solid surfaces

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between ...
