A new high-powered microscope has allowed scientists to watch a zebrafish develop from a single cell into an embryo with a beating heart, the first time this has been possible in vertebrates, ...

At just two-and-a-half hours old, a teensy fruit-fly embryo is bustling with activity, and now researchers have captured this development in a 3-D video showing a young embryo grow into a 20-hour-old ...

A stunning photograph of a fluorescent turtle embryo under a microscope has scooped the top prize in this year's Nikon Small World photomicrography competition, which celebrates photographs taken of ...

At just two-and-a-half hours old, a teensy fruit-fly embryo is bustling with activity, and now researchers have captured this development in a 3D video showing a young embryo grow into a 20-hour-old ...

With the development of an adaptive, multi-view light sheet microscope and a suite of computational tools, researchers have captured the first view of early organ development inside the mouse embryo.

Compared to the low-tech way of studying development in mice — scrutinizing day-old mouse fetuses, then another bunch that are an hour older, and more that are two hours older, and so on up to the end ...

A new microscope developed at the Howard Hughes Medical Institute's Janelia Research Campus is giving scientists a clearer, more comprehensive view of biological processes as they unfold in living ...

A smart new microscope has given scientists a front-row seat to the drama of mammalian development. For the first time, researchers can now peek inside a living mouse embryo and watch the gut begin to ...
