The 7th Peptoid Summit:
Progress in peptoid toolkit development

August 13, 2010

The 7th Peptoid Summit highlighted progress in design technology for one of the most promising toolkits in modular molecular systems engineering.
I’ve outlined the submonomer method for peptoid synthesis as a powerful and convenient way to assemble diverse molecular components, and the recent development of crystalline peptoid nanosheets as a platform for extended atomically-precise structures. The [...]

Autophagy:
Why you should eat yourself

July 24, 2010

I’d like to say a few words about one of the hottest and, in my view, most important areas in biomedicine: autophagy, a process crucial to health, disease, and aging. Autophagy research is expanding rapidly.
In autophagy (“self eating”), cells engulf and digest their own macromolecules and organelles. Autophagy serves two functions: providing critical nutrients in [...]
