Photo: Eye overlaid with transparent images [10/06/2014] In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people, the researchers say.Making artificial vision look more natural - Read more

Photo: Illustration of a man cutting DNA with scissors [23/05/2014] Slight modifications in their genome sequences play a crucial role in the conversion of pluripotent stem cells into various differentiated cell types. A team at Ludwig-Maximilians-Universitaet (LMU) in Munich has now identified the factor responsible for one class of modification.Genetic switching element in stem-cell research - Read more

Photo: Microchip [19/05/2014] A U.S. and Korean research team has developed a chip-like device that could be scaled up to sort and store hundreds of thousands of individual living cells in a matter of minutes. The system is similar to a random access memory chip, but it moves cells rather than electrons. Microchip-like technology allows single-cell analysis - Read more
