Oct 31, 2012A new study provides a detailed picture of how opsins evolved. Opsins are light-sensitive molecules found in photoreceptor cells of the retina. -
Oct 31, 2012Um novo estudo provém um retrato detalhado de como as opsinas evoluíram. Opsinas são moléculas sensíveis à luz encontradas em células fotorreceptoras da retina. -
Oct 27, 2012A new study indicates that bacteria may have helped kick off the leap from single celled organisms to multicellular organisms. -
Oct 26, 2012Researchers have discovered more evidence of preserved dinosaur proteins. Their findings support the case for preserved cells in ancient remains. -
Oct 14, 2012A new concept is challenging one of the basic assumptions of the theory of evolution - that survival is based on a change's functional advantage if it is to persist. -
Sep 29, 2012New research on a lizard-like amphibian highlights how difficult it would be for humans to regenerate a limb or organ. -
Sep 28, 2012New research supports the idea that microorganisms embedded in the fragments of distant planets may have traveled to the early Earth and seeded our planet with life. -
Sep 26, 2012Scientists have discovered an unusual symbiosis between tiny single-celled algae and highly specialized bacteria in the ocean. -
Sep 21, 2012In order to understand how life began on Earth, researchers are creating concoctions of organics on ice and zapping them with lasers. The study provides the first look at organic chemistry on icy particles in the frigid reaches of our solar system. -
Sep 16, 2012Sixty-five million years ago, a mass extinction on Earth wiped out the dinosaurs. New research now indicates that a separate extinction event occurred shortly before that, triggered by volcanic eruptions that warmed the planet.
