If we really want to know how our body's cells work—or don't work, in the case of disease—we might need to look beyond their genes and even beyond the proteins they are made of. We may need to start going through the ...

With woodpeckers, the answer's in the question—true to their name, they peck wood. And when they do, they peck hard—with each peck, the bird undergoes a force of 1,200 to 1,400 g's. By comparison, a measly force of 60-100 ...
