Final piece of protein puzzle: NMR tops and tails HIV

Date: Nov 1, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has been used to put in place the final piece of the HIV-1 protein structure, the cytoplasmic tail of gp41 protein. The research by a team at the University of Alabama at Birmingham led by Jamil Saad will help scientists better understand how the virus infects human cells and how progeny viruses are assembled and released from infected cells.

Life on Earth: UV and HCN

Date: Nov 1, 2017

Author: David Bradley

UV-Vis spectroscopy has revealed that the experimental conditions for the polymerization of aqueous HCN (hydrogen cyanide) affect the kinetics of the reaction. Given the purported role of HCN in the prebiotic organic chemistry of our planet, such insights might ultimately have implications for our understanding of how life on earth began.

Influenza A proteins: Individual proteome variations

Date: Oct 15, 2017

Author: Steve Down

Scientists in the US have shown that the proteomes of normal human bronchial epithelial cells are unique for individual people and also respond to infection by the influenza A virus in different ways, findings which could be used to identify people more susceptible to the disease.
