Ringing the changes: Environmental endocrine detection

Date: Mar 1, 2013

Author: David Bradley

Cyclodextrin, the natural starch ring molecule, can be used to create a sensitive coating on gold for surface enhanced Raman spectroscopic (SERS) detection of endocrine disrupters present in environmental water samples, according to a new study.

Water, water everywhere: Even on the Moon

Date: Mar 1, 2013

Author: David Bradley

An analysis of tiny mineral deposits from lunar anorthosites brought back to Earth by Apollo astronauts adds new evidence to suggestions that water was not lost to space during the formation of the Moon. The analysis was carried out using Fourier-transform infrared (FTIR) spectroscopy.

Alcoholic proteomics: Ethanol effects on proteins in rat liver and serum

Date: Feb 15, 2013

Author: Steve Down

A dual approach to proteomics changes in the rat following a chronic alcohol diet has examined both serum and rat liver, revealing that only one protein was up-regulated in both matrices.

Pablo Picasso: Decorator

Date: Feb 15, 2013

Author: David Bradley

What type of paint did one of the most renowned and infamous artists of the twentieth, century, Pablo Picasso, use in his work - matte, gloss or emulsion? The Art Institute of Chicago and scientists at Argonne National Laboratory think they know having used a hard X-ray nanoprobe to help them unravel what is a decades-long debate among art scholars.

Wonderful webs: Elastic data analysed

Date: Feb 15, 2013

Author: David Bradley

The full range of elastic properties of an intact spider's web have been catalogued by researchers in the USA using the relatively uncommon technique of Brillouin spectroscopy. The research offers an intriguing picture not only of one of nature's most fascinating structures but might also point the way towards novel "bio-inspired" materials.

Pores for thought: Just shine a light

Date: Feb 15, 2013

Author: David Bradley

Nuclear magnetic resonance spectroscopy and mass spectrometry, among other techniques have been used in work on polymer pores. While, irradiation with light is a wel-established approach to the initiation of polymerization as well as cross-linking (or curing of polymers) during plastics production, researchers in the USA have now demonstrated that light can be used to retroactively increase the size of the pores within a polymer network.
