Gigapixel 3D microscope captures life in unprecedented detail

Researchers have developed a new type of microscope that stitches together video from 54 individual cameras and lenses. Whether recording high-speed, 3D, gigapixel movies of the behavior of dozens of freely swimming zebrafish or the grooming activity of fruit flies at near cellular-level detail across a very wide field of view, the device is opening new possibilities to researchers the world over.

Study uses base editing to correct mutation that causes rare immune deficiency

A condition called CD3 delta SCID is caused by a mutation in the CD3D gene, which prevents the production of the CD3 delta protein that is needed for the normal development of T cells from blood stem cells. Researchers showed that a new genome editing technique called base editing can correct the mutation that causes CD3 delta SCID in blood stem cells and restore their ability to produce T cells....
