New protocol for flourescence imaging visualizes more than 50 proteins.

What cell types are found in which human tissue, and where? Which genes are active in the individual cells, and which proteins are found there?

This stunning image of the human retina bursts like a work of art! Is it an eye? Or is it a painting that deserves to be hung at the Louvre? Well, get ready to be amazed by the stunning image of the human retina that looks like an absolute work of art! Researchers from ETH Zurich and the Universities of Zurich and Basel have created a new method to collect and organize information about organoids, which are small three-dimensional tissues that resemble human organs.

The technique enabled researchers to map the development of human retinal organoids at high temporal and spatial resolution, providing insights into how healthy tissue forms and developing a time series that describes the entire 39-week development of retinal organoids.

Scientific American Experiments on clusters of cultured cells hint that a gene variant found only in Homo sapiens profoundly changed brain development in our species, compared with our extinct relatives Advertisement We take it for granted that  Homo sapiens is the only human species in existence, but it didn’t use to be this way. From the origin of our species a few hundred thousand years ago until a few tens of thousands of years ago, multiple human species shared the planet with our own. What distinguished H. sapiens from other members of the human family, and why did our lineage alon...
