rssJournal Highlight: Tissue proteomics of the low-molecular weight proteome using an integrated cLC-ESI-QTOFMS approach
Date: Jun 24, 2013
Author: spectroscopyNOW
A tissue proteomics approach involving tissue homogenization followed by depletion of large proteins and then capillary LC-MS analysis has been evaluated for examining the low molecular weight/low abundance tissue proteome.

Quasi on the inside: Rare earth crystals
Date: Jun 15, 2013
Author: David Bradley
Scientists at the Ames Laboratory in the USA have used an algorithm to fish for new rare-earth quasicrystals and have pulled out a new family of binary magnetic icosahedral quasicrystals containing several different rare earth elements and cadmium. The findings demonstrate that such materials have spin glass behaviour rather than magnetic behaviour.

Invisible touch: What's the matter?
Date: Jun 15, 2013
Author: David Bradley
An explanation as to why we cannot detect 85 percent of the predicted mass of the universe has emerged from fundamental particle research carried out in the 1930s. US physicists have now proposed that dark matter, may be composed of Majorana fermions, which are anapoles with a doughnut-shaped electromagnetic field invisible to any known detector technology.

Journal Highlight: Time-resolved X-ray PIV technique for diagnosing opaque biofluid flow with insufficient X-ray fluxes
Date: Jun 10, 2013
Author: spectroscopyNOW
X-ray particle image velocimetry in which an image intensifier was combined with a high-speed camera was used to reduce exposure time to below 200 µs, and applied to measure high-speed blood flows in a tube
