A single-celled organism has no brain and no nervous system, so you wouldn't think it could have an eye. But the dinoflagellate Erythropsidinium is able to "see" polarised light, and aim its piston accordingly.
The iconic 3D holographic computer interfaces from the Iron Man movies and Minority Report might be not far off, as researchers in Japan have developed a way to suspend light in mid-air and make it safe to interact with.
Approximately 2.1 billion years ago saw the emergence of multicellular organisms. New research suggests that the leap from single-celled life to multicellular creatures may have been fairly simple, and there may have been more than one way it happened.
Researchers at the University of Bristol have developed a system for self-healing aeroplane wings. The material, which uses a liquid carbon-based "healing agent" could also be used for bicycle frames and wind turbines.
A dramatic increase in raven population in the Mojave Desert is threatening a rare desert tortoise. Some conservationists have turned to technology to ward off the ravens - they're shooting them with lasers.
