Guts against Diabetes
Mar 21st
For a very long time I have been using Diabetes as an example of a disorder that is caused by a mutation in the insulin gene. This mutation would stop the cells from making insulin, and a diabetic might need daily insulin injections to regulate their sugar levels properly. I don’t know what took me so long to realize that this was completely wrong. That while some diabetics are insulin dependent, it is because their insulin-producing cells of the pancreas are being completely destroyed by the immune system. And while they still aren’t sure about why these cells are being More >
What do you get when you cross an immunologist, a nanotechnologist, and a geneticist? A DNA nano-robot!

Welcome to the world of nanobiotechnology and translational research…
In a brilliant example of multidisciplinary research, Harvard Medical School’s Shawn Douglas, Ido Bachelet, and George Church combined forces to build nanostructures that would mimic the body’s immune system to recognize cancer cells and trick them into self-destructing. Their research is published today in Science but the discovery didn’t just happen overnight. It’s the culmination of several key discoveries going back several years, by researchers around the globe.
In 2006, Paul Rothemund at the California Institute of Technology, discovered “DNA origami,” where the Watson-Crick base-pairing rules are exploited to create molecules from viral DNA More >
