Subscribers to the scientific journal CELL MOTILITY now receive supplemental video disks, so they can observe the cell movements described in the journal articles. "Viewers of these video disks can reanalyze the raw data and draw their own conclusions," says the journal's editor, Robert D. Allen of Dartmouth College in Hanover, N.H., who has developed a method of microscopy that enhances images by using video displays (SN: 4/11/81, p. 234).

* A new resource for geneticists may soon be the pedigrees of the Daughters of the American Revolution (DAR). The national society has announced a "DAR Family Tree Genetics Project" in conjunction with the Vanderbilt University Medical Center in Nashville, Tenn. The group's 210,000 members have been asked to response to a confidential survey about their ancestors' deaths and about health problems of recent generations. These families have unusually extensive historical records -- to be a DAR member, a woman must be able to prove that she is a descendant of a Revolutionary War soldier.

* An expanded version of the "Exploring Microscope" exhibit (SN: 3/31/84, p. 204) has opened in New York City at the IBM Galaery of Science and Art. The show now includes a more extensive history of microscopy, more exhibits of modern, specialized instruments, including an X-ray microscope, and six microscopes for visitors to try out for themselves.
