Journal Highlight: Chemometrics application in biotech processes: assessing comparability across processes and scales

Date: Oct 20, 2014

Author: spectroscopyNOW

Chemometrics has been applied to compare two versions of a biotech process and identify process steps where significant differences exist as well as the parameters that cause these differences.

Ozone liver stress: Inhalation alters hepatic proteome

Date: Oct 15, 2014

Author: Steve Down

Exposure to ozone modifies the proteome of the rat liver, according to scientists in the USA, compounding the adverse health effects that are already recognised in other organs like the lungs and heart.

Antarctic amino acids: Chiral differentiation

Date: Oct 15, 2014

Author: Steve Down

L- and D-amino acids in Antarctic lakes have been separated and measured by a novel LC/MS procedure with the best reported detection limits to date, allowing those produced by bacteria to be distinguished from natural amino acids.

No seasoning: Fluctuating flux flummoxed

Date: Oct 15, 2014

Author: David Bradley

The decay rate of certain radioactive nuclides does not fluctuate with the terrestrial seasons because of changes in the flux of solar neutrinos passing through our planet, according to new research that debunks the hypothesis.

To dye for: No more

Date: Oct 15, 2014

Author: David Bradley

A combination of an iteratively cubic spline fitting baseline correction method with discriminant partial least-squares qualitative analysis can be used to pluck evidence of banned additives from food samples analysed with surface-enhanced Raman spectroscopy (SERS), quickly revealing the presence of compounds such as Sudan I dye, Rhodamine B and Malachite green.

Dancing proteins: HIV targets

Date: Oct 15, 2014

Author: David Bradley

New targets for preventative therapies of HIV infection might now be possible thanks to new studies that reveal the 'dance' of HIV proteins on the surface of the virus that are thought to be involved in the infection of human immune cells.
