...molecule. The dispute is still not entirely settled, but the electron microscope shows that many of them look and act like living things. At a recent American Medical Association symposium, leading U.S. virologists described an amazing variety of viruses, ranging from types that attack only bacteria to those that infect...
...fear from viruses than from bacteria. An outstanding fact about viruses, says he, is that their well-being depends on the health of their host. Unlike bacteria and insects, which are often out-&-out rivals of man, viruses can live only as long as the human being they infect. Unfortunately for the host, viruses often commit suicide by killing the patient. But in the long run, says Burnet, the virus varieties with the best chance of survival are those that "live & let live." Many of the viruses that infect man have evolved into forms that produce low-grade infections, often...
Bacteria found in deep sea mud might soon make oil wells as buggy as vinegar works. Last week Dr. Claude E. ZoBell, of the Scripps Institution of Oceanography, La Jolla, Calif., announced that he was well along on a process to infect exhausted oilsands with these bacteria...
...market is an artificial frost for potatoes. When late potatoes reach maturity, farmers pray for frost to kill the vines. If it does not come, a lot of evils may. Potatoes grow lopsided, bumpy. Juicy vines clog the digging machinery, and blight spores from their still green leaves may infect the harvest...
Blister rust cannot live on pine alone. The spores which leave the pine must find a temporary resting place on the leaves of currant or gooseberry bushes. There they develop as parasitic growths which generate a new and different generation of windborne spores which, in turn, infect the pines. These bushes are the chief points of attack for the conservation army. Once the host is destroyed, blister rust must ultimately...
