 Nampak Tissue is teaming up with Noah charities and Street Children initiatives to ensure it too can contribute in keeping South Africa's less fortunate children warm this winter. This will be achieved through a competition initiative, which will support the Twinsaver 'Softer Side of South Africa' campaign. Read more >>Medical Research
In a paper in the journal Genetics, a research team at Worcester Polytechnic Institute reports that yeast produce a hormone previously known to be made by plants, and that the hormone can trigger fungal cells to become more infectious.

However, the mechanisms governing DNA mutation rate are not well understood. In a report published online today in Genome Research ( www.genome.org), researchers have identified intrinsic properties of DNA that influence mutation rate, shedding light on mechanisms involved in genome maintenance and potentially disease.

Scientists at NYU Langone Medical Centre have discovered that the strategy of "immune evasion" common to many viruses, bacteria and parasites, is uncommon to M. tuberculosis where the antigens remain strikingly unchanged and homogenous. The study published in Nature Genetics on May 23, 2010, suggests that M. tuberculosis antigens do not mutate because they hope to be recognised by the body's immune system- perhaps because the host immune mechanism that leads to the typical lung destruction and cough can contribute to the spread of the disease. This finding has the potential to change the direction of vaccine research and could result in a new focus on different targets of immune response to the bacteria. Read more >>
