Researchers grow 'human embryos' from skin cells: What does that mean, and is it ethical?

Researchers have successfully grown model versions of early human embryos by "reprogramming" cells from human skin. The breakthrough potentially opens up new ways to study the earliest phases of human development, learn more ...

New technique reveals genes underlying human evolution

One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, ...

RNA detection method advances in situ transcriptomics with potential for a range of biomedical applications

Human cells typically transcribe half of their roughly 20,000 genes into RNA molecules at any given time. Just like with proteins, the function of those RNA species not only relies on their abundance but also their precise ...

Researchers grow most lifelike bone yet from woven cells

Imagine using stem cells from your bone marrow to grow a piece of bone tissue in the lab, after which medical doctors explore which drugs have the desired effect on your bones. In this way, a tailor-made treatment plan would ...
