Leona Samson, left, and Dr. Rebecca Fry have found that prenatal exposure to arsenic leads to alarming changes in the genetics of newborn babies. Samson is the director of MIT's Center for Environmental Health Sciences (CEHS) and the American Cancer Society Professor in the Departments of Biological Engineering and Biology. Fry is assistant scientific director of CEHS.

Here, dark gray nanoparticles carry different drug payloads (one red, one green). A remotely generated five-minute pulse of a low-energy electromagnetic field releases the green drug but not the red. A five-minute pulse of a higher-energy electromagnetic field releases the red drug, which had been tethered using a DNA strand twice as long as the green tether, as measured in base pairs.

Top panels: Cells of the intestinal lining of mice lacking the embryonic pluripotency regulator Oct4 stop dividing and die after radioactive exposure. Middle panels: Intestinal stem cells then become activated and begin dividing rapidly. Bottom panels: The intestinal lining is completely regenerated, with stem cells relocating to the bottom.

Adult stem cells lack key regulator
