...ymers. But could this approach be used to make the more difficult to synthesize shaped molecules needed for mapping a receptor? This would require a diverse array of reactions to be compatible with the chips, particularly reactions that capitalized on modern, state-of-the-art metal-based reagents. Worki...

The study, which was lead by Frank McKeon, PhD, professor of cell biology at Harvard Medical School (HMS), shows that p63’s role in not in tissue differentiation but rathe...

Fuel from fiber -- Pretreatment can put corn stalks, trees in your car's tank

Corals -- More complex than you?

...coral may possess as many genes ?and possibly even more ?than humans do. And remarkably, although it is very distant from humans in evolutionary terms, it has many of the immune system genes that protect people against disease.
