...expression of these genes may help the parasite to escape the host organisms immune responses, although the researcher points out that this is yet to be confirmed. The researchers discovered that the silencing mechanism happens at the epigenetic level, meaning that the parasite stops expressing a certain ...Report recommends off-site disposal of secondary waste

The committee found that on-site treatment of the carbon followed by its incineration has been problematic at best, and recommends that off-site...A brain chemical that battles despair

... "This paper explains how a pathogen can evolve to escape detection," said lead author Tracy Rosebrock, a graduate student in Cornell's Department of Plant Pathology and BTI. "The bacterium has one specific protein that it uses to turn off the plant's immunity." The researchers found that the Fen gene is pr...Immune system 'escape hatch' gives cancer cells traction

Peroxynitrate activity is the escape hatch, and now that we have identified it, we can try to cut it off before T-cell tolerance develops...... and can detect hidden tumors that might otherwise escape notice. However, MRI is so sensitive that it reveals even non-cancerous suspicious growths in the breasts, resulting in many unnecessary biopsies and additional scans, not to mention heightened anxiety. In this new combined approach, any suspect l...Nanoparticles hitchhike on red blood cells: a potential new method for drug delivery
