Audubon Society President Elvis J. Stahr. With the figures the volunteers provide, ornithologists are able not only to check the health and vigor of different avian species but also to detect changes in their habitats, set up wildlife sanctuaries and even help airlines reroute their planes to avoid dangerous collisions with migrating birds. The bird count also acts as an environmental early-warning system. Recalling the canaries that miners took with them into coal mines to detect noxious fumes, Stahr explains that birds are usually quicker than man to react to changes about them.

...Lasker jurors as perhaps the most important nonsurgical tool for heart diagnosis since the development of the electrocardiograph, the technique uses the familiar sonar echo principle: high-frequency (and inaudible) sound waves reflected from a target reveal its characteristics.

Using radioactive isotopes as tracers in the so-called immune reactions by which the body's antibodies combine with foreign antigens, the test was sensitive enough to detect exceedingly minute quantities of a substance...
