These elements would ultimately come to be known as isotopes, but at the time this concept was

Male rhesus monkeys with destroyed amygdala will abandon their normally slow and cautious familiarization process and immediately approach other monkeys with whom they are unfamiliar, according to David Amaral, professor of psychiatry and neuroscience at the University of California, Davis. His study on these animals is slated to appear in an upcoming issue of Behavioral Neuroscience. The study involved six lesioned monkeys, each meeting for many 20-minute sessions with a "stranger" monkey. The

The E-Nose: Scientists Compete with Nature's Prolific Sniffers
Brendan Maher | Sep 29, 2002 | 6 min read
Illustration: Ned Shaw Volatile odorants spewing forth from every living thing reveal a hidden trove of factors like diet, health, and genetic composition. With astonishing acuteness, most animals can read these olfactory messages and model their behaviors accordingly. "Odors are their windows on the world," one researcher says of mice. Others have noted that some honeybees recognize illness in hives and avoid them.1 Dogs have alerted their owners to such maladies as melanoma2 and epileptic se
