Leech-Repellent Property of Eastern Red-Spotted Newts, Notophthalmus viridescens
(American Association for the Advancement of Science: Science, 1971-12-10)Eastern red-spotted newts (Notophthalmus viridescens, Salamandridae) are rarely attacked by leeches. This protection is not shared by related salamandrids or by Ambystoma (Ambystomatidae). Tetrodotoxin is not the repelent. ... -
Nonstationary behavior of collisionless shocks
(American Physical Society, 1972-01-03)Laboratory measurements indicate that a collisionless shock wave formed in a plasma-wind- tunnel device is nonstationary on the time scale of the ion gyroperiod. This behavior suggests a possible interpretation of recent ... -
