A team of scientists has identified an unexpected embryonic "starting point" for several brown-fat depots: a small cell niche around the dorsal aorta. Using a combination of time-controlled genetic ...

Abstract: High-precision three-dimensional imaging of live embryos is hindered by photobleaching, invasive labels, and the mechanical constraints of conventional rotation methods. To overcome these ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...
