Disease inheritance: the long-term effects of pesticide exposure (Reviving Gaia)

When looking at pesticide exposure, it’s important to think about long-term effects. I’m not just talking about “30 years from now” long-term, but the effects your exposure might have on your future descendants, even if they are never directly exposed to pollutants. This concept of disease inheritance is one of the most interesting (and frightening) new phenomena to be discovered in the past few years. An example of this was recently described in a study that showed DDT exposure could increase rates of obesity several generations down the line.

Stem cell transplant problem solved, UCSD-led study says (U-T)

One of the toughest problems facing embryonic stem cell therapy, immune rejection of transplanted cells, may have been solved, according to a UC San Diego-led research team.  The cells can be made invisible to the immune system by genetically engineering them to make two immune-suppressing chemicals, according to a study performed in mice given a human immune system. Immune functioning in the rest of the animal remains active.  If the approach works in people, patients receiving transplanted tissue or organs made from embryonic stem cells wouldn't have to take harsh immune-suppressing drugs, said Yang Xu, a UCSD professor of biology.
