At a recent virtual Clinical Center Grand Rounds Great Teachers talk, NCI's Dr. Stephen Chanock managed to fit his professional journey, career advice, a history lesson and decades of research into a captivating hour.
Genomics can help solve animal cruelty cases, prosecute wildlife crimes and conserve endangered species, said Dr. Rebecca Johnson. “DNA can really be a valuable tool for fighting wildlife crime when combined with museum collections,” she said at the during the recent Louise M. Slaughter National DNA Day lecture.

Multi-Nucleated Muscle Cells Grown in Culture. The cells have fused together to form myotubes that have many nuclei (stained blue). The cells are from mouse skeletal muscle stem cells treated with a harmless virus that caused them to glow green. The green color remained when the stem cells fused into myotubes. Some myotubes are stained red for a protein involved in muscle contraction (myosin heavy chain), a characteristic of mature muscle fibers. Researchers plan to use the same viral delivery system to genetically modify the cells and assess how impairing cell fusion alters myotube growth. The image was a 2017 winner in the BioArt competition of FASEB.
