Potable Water and HIV

Meera Senthilingam

This week, we investigate the workings of the HIV virus to find out just how the virus hijacks our immune system as well as discover a new form of tea bag that filters and sterilises water, to make it potable. Also, how the taste of bitterness could treat asthma, a revelation of vegetables in the diet of our stone-age ancestors, and gene therapy for depression!
