Binding of Cyclopropane to Sperm Whale Myoglobin

Nature, 1967
THIS article follows reports of the binding of xenon, an anaesthetic agent, to sperm whale met and deoxymyoglobin1,2. X-ray diffraction analysis showed that a single xenon atom binds to the same specific site in both derivatives. This site is located at a cavity in the interior of the molecule, about equidistant from the haem linked histidine and one ...

Acoustics and the Behavior of Sperm Whales

1980
The first good recordings of underwater sperm whale sounds that we have were made 27 years ago (22 April 1952, R/V Caryn at 38°29′N, 69°29′W) and five years later the sounds were identified definitely and described (Worthington and Schevill 1957). At every opportunity since then, we have stopped with these whales and listened underwater (Watkins 1977).
