On Monday, I mentioned that it was a good week for women in science. Well, it got even better today with the announcement of the chemistry prize. Ada Yonath of the Weizmann Institute of Science becomes the fourth woman to be awarded a Nobel Prize in Chemistry (sharing the prize with Venkatraman Ramakrishnan of the…
It’s Nobel Prize season again, and the science behind this particular award for Medicine feels like a familiar friend. I got my crash course in telomeres and telomerase from a group meeting talk that one of my lab colleagues gave almost exactly a decade ago. The science recognized was done a quarter century ago. DNA…
Creating a genetic program to crinkle DNA into the perfect shape can appear to be a scientific stunt. But DNA origami is more than a molecular magic trick. In this excerpt from a 2007 TED lecture, Paul Rothemund describes the science behind the work– how a chain– based on its sequence– becomes a two-dimensional shape.…
You have it, I have it. Many viruses are based on it. It’s RNA, which stands for ribonucleic acid. It’s DNA’s chemical cousin with just a few slight differences. While DNA serves as life’s genetic blueprint. RNA is more of a multitasker. DNA stores information in a kind of vault, and the cell makes RNA-based…
