...producing frogs that were genetically identical to each other and carried the inherited characteristics of only a single parent. Most animal cloning has been done by transplanting nuclei into egg cells to produce an entire organism from a single cell. But the cloning of higher forms of life, like mammals, is hard to achieve. Mammal eggs are microscopic, ten to 20 times smaller in diameter than frogs' eggs, and vastly more difficult to manipulate. Consequently, the barriers to cloning laboratory mice had, until now, proved insurmountable. But last week the word was out that biologists had successfully done just...
Some legislation is already in effect to help save the manatees. The 1972 Marine Mammal Protection Act prohibits molesting, capturing or killing them, and is backed by stiff fines and jail terms for offenders. The 1978 Florida Manatee Sanctuary Act restricts boat speeds in critical areas (maximum penalty: $1,000 and a year in jail) and even forbids divers from enticing the animals into underwater play...

Chicago's Brookfield and Lincoln Park zoos raise much of their mammal fodder hydroponically and claim that their greens are particularly nutritious...

The whale is a mammal. It makes love. It is warm-blooded. It has been here 40 million years longer than we have...
