Using newly available genetic sequencing scientists discovered cells infected with prions (the infectious agent responsible for these diseases) release particles which contain easily recognized 'signature genes'.

The ageing process has its roots deep within the cells and molecules that make up our bodies. Experts have previously identified the molecular pathway that react to cell damage and stems the cell's ability to divide, known as cell senescence.

Menachem Shoham, PhD, associate professor of biochemistry at Case Western Reserve University School of Medicine, has discovered novel antivirulence drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) and Streptococcus pyogenes, commonly referred to as strep, harmless by preventing the production of toxins that cause disease. The promising discovery was presented this week at the Interscience Conference on Antimicrobial Agents and Chemotherapy in San Francisco.
