Fish eyes grown in a petri dish from embryonic stem cells

A research team from the Centre for Organismal Studies (COS) of Heidelberg University has demonstrated that complex retinal tissue can be cultured in a Petri dish from embryonic stem cells of bony fish. Until now, stem cells ...

Deep-sea vision linked to night life on the reef

To see—and survive—at night, some coral fish have developed visual adaptations that are similar to those of their cousins living in the ocean's darkest depths, new research shows.

The genetic secret of night vision

One of the most remarkable characteristics of the vertebrate eye is its retina. Surprisingly, the sensitive portions of the photoreceptor cells are found on the hind side of the retina, meaning that light needs to travel ...

Finding a cell's true identity

Scientists have long sorted cells into different varieties based on their appearance under a microscope or, for differences that are more visually subtle, based on the behavior of a handful of genes. But in a bid to reveal ...

Curing blindness with stem cells – here's the latest science

In 2006, Nature published a paper describing how stem cells could be used to restore sight in blind mice. This study, and similar subsequent studies, created a lot of excitement about the potential of stem cells to cure blindness ...
