"Instead of being lashed to a lab bench for years, carrying out experiments to illuminate one particular fold in one particular protein, we [science writers] get to play the field. We travel between different departments, different universities, different countries, and—most important of all—different disciplines. And sometimes we see links between different kinds of science that scientists themselves have missed. Which is why... I presented my audience with this photograph of a lake. For the next hour, I tried to convince them that their bodies are a lot like that lake, and that appreciating this fact could help them find new ways to treat diseases ranging from obesity to heart disease to infections of antibiotic-resistant bacteria." Carl Zimmer's talk on the importance of the human body's microbial system. A long read, but fascinating stuff [c/o Kottke].
