...state entomologist at the Shade Tree Laboratory Field Station in Waltham suggested that a commercial preparation of the bacterium Bacillus thuringiensis might keep the moth population down for several years while the natural predators re-establish themselves. This particular biological control has recently halted the cabbage looper and fruit cankerworm, but it has not been tried against the ivy moth...
...extract this gene, the scientists took advantage of the fact that when a virus infects a bacterium it sometimes removes a piece of the bacterium's DNA. They infected E. coli with two types of viruses that were specifically bred to remove the lactose gene from E. coli...
...only like other creatures in diverse elements, but in divided and distinguished worlds.' " Night Journey seems to have reminded Poons of two such divided worlds. One is a sun lit, sandy sea inhabited by bright-colored forms, the other a smoggy pink one in which one lonely bacterium floats...
...forever above lower orders of creation. This hypothesis, once generally held, and still held by orthodox Christians, is now challenged by widespread acceptance of the "materialist hypothesis"-the notion that man is merely a more complicated organism in a hierarchy of natural history extending down to the smallest bacterium...
Electron microscopists have since photographed lysosomes, and Dr. de Duve, now at Rockefeller University, has figured out some of the ways they work (see diagram). In a typical case, a foreign particle (it may be a virus, a bacterium or a chemical) reaches the side of a cell and is sucked in, sealed off by a piece of the cell's own membrane. Standing by inside the cell is a lysosome, packed with enzymes. Lysosome and invader, now packaged in a phagosome, are drawn together and fuse. In the resulting sac, called a vacuole, the foreign substance is digested...
