New American Chemical Society podcast: Big building blocks from nanoparticles

A new genre of construction materials, made with particles barely 1/50,000th the width of a human hair, is about to play a big role in the building of homes, offices, bridges, and other structures, according to the latest episode in the American Chemical Society's award-winning podcast series, 'Global Challenges/Chemistry Solutions'.

How do your crystals grow?

New research uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS can resolve dimensions as small as a single wavelength of the light.

Scientists warn geo-engineering unlikely to curb dramatic sea rise

Researchers from Europe and China warn that little can be done to stop dangerous increases in the global sea level, as it will rise between 30 to 70 centimetres (cm) by 2100 even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and stringently control greenhouse gas emissions.

New artificial skin could make prosthetic limbs and robots more sensitive

The light, tickling tread of a pesky fly landing on your face may strike most of us as one of the most aggravating of life's small annoyances. But for scientists working to develop pressure sensors for artificial skin for use on prosthetic limbs or robots, skin sensitive enough to feel the tickle of fly feet would be a huge advance. Now Stanford researchers have built such a sensor.
