Scientists have been trying to figure out how it is possible for bacteria to perceive light and react to it ever since they started using microscopes 300 years ago. Scientists have now solved this ...

Seeing the light: model of how a bacterium focuses light. (Courtesy: Ronald Kampmann/KIT) Microscopic organisms called cyanobacteria form tiny lenses similar to the human eye to detect light and move ...

Physicists in the US have made the first ultrathin flat lens. Thanks to its flatness, the device eliminates optical aberrations that occur in conventional lenses with spherical surfaces. As a result, ...

Some cyanobacteria are tiny, photosynthetic Beholders(Opens in a new window), according to an international team of scientists. We already knew that Synechocystis bacteria are pretty good at managing ...
