Can a moisturizer treat cancer?
Aug 17th
How often do you moisturize your skin? Every day? Once a month? Well researchers at Northwestern University in Chicago have given a moisturizer the ability to perform RNA interference and regulate genes.
Topical treatments are common for skin cancers like melanoma, as they can be applied directly to the affected cells. But our skin is very effective at blocking toxins getting into our bodies so the challenge was how to cross that barrier.
Again, enter the realm of nanotechnology, a topic I post about regularly.
This time, the scientists paired gold nanoparticles with small interfering RNA (siRNA) molecules to form a siRNA “sphere.” These miniscule 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 >
