Water helps assembly of biofibers that could capture sunlight

A new study from Argonne National Laboratory has shown water can serve a previously undiscovered role to help micelles coalesce to spontaneously form long fibers. The study could help scientists to understand how light-harvesting molecules are incorporated into the micelle fiber as it assembles, which would be a key step to understanding some forms of artificial photosynthesis.When it comes to water, some materials have a split personality - and some of these materials could hold the key to new ways of harnessing solar energy.

Astronomers observe star reborn in a flash

This image of the Stingray nebula, a planetary nebula 2400 light-years from Earth, was taken with the Wide Field and Planetary Camera 2 (WFPC2) in 1998. In the centre of the nebula the fast evolving star SAO 244567 is located. Observations made within the last 45 years showed that the surface temperature of the star increased by almost 40 000 degree Celsius. Now new observations of the spectra of the star have revealed that SAO 244567 has started to cool again.An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the...
