A new microscope is giving researchers an unprecedented view of how mammals are built, cell by cell. Light sheet microscopes use ultrathin laser beams to illuminate sections of a specimen while ...

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 ...

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 ...

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.

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 ...

"This microscope is very, very, very unusual," says Keller, a developmental biologist and optical physicist at the Howard Hughes Medical Institute's Janelia research campus. That's because it's built ...

Researchers at the European Molecular Biology Laboratory (EMBL) have generated a digital zebrafish embryo - the first complete developmental blueprint of a vertebrate. With a newly developed ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 ...
