متن کاملEvolving eyes.
Despite the incredible diversity among extant eyes, laws of physics constrain how light can be collected resulting in only eight known optical systems in animal eyes. Surprisingly, all animal eyes share a common molecular strategy using opsin for catching photons, but there are a diverse collection of mechanisms with proteins unrelated to each other used to focus light for vision. However, opsi...
متن کاملEyes East
Last November I visited Japan for the first time and was lucky enough to visit individual labs at four different universities. As I talked with my hosts and their students I was struck by the differences between the scientific cultures of Japan and the United States. At its best, American science is all about the triumph of excellence in the land of opportunity, with 27-year-old assistant profe...
