Cold currents flowing toward the Equator in the deep ocean are often agitated by powerful storms. These disturbances transport huge volumes of sediment across the ocean bottom
How Genes Control an Innate Behavior
The techniques of recombinant DNA are exploited to define a family of genes encoding a set of related neuropeptides whose coordinated release governs a fixed-action pattern: egg laying in a marine snail...
The Descent of Hominoids and Hominids
Findings over the past five years have made it possible to trace with greater assurance the divergence of the apes from the Old World monkeys and the later divergence of humans from apes...
Excitonic Matter
A conduction electron can combine with a positively charged hole in a semiconductor to create an exciton. Excitons in turn can form molecules and liquids, and a new phase of matter may be attainable...
Muscle Sounds
Contracting muscle generates distinct sounds that are not heard only because the human ear is insensitive to low frequencies. Such sounds are now studied for their possible usefulness in science and medicine...
The Adaptability of the House Mouse
The reproductive abilities of this small mammal are remarkably flexible. It is for this reason that the species flourishes in a great diversity of habitats, notably those it shares with human beings...
Florence Nightingale
She saved the lives of thousands of soldiers in the Crimea and was one of the founders of modern medical care. She was also a pioneer in the uses of social statistics and in their graphical representation...
