...virus was chemically different from all previously identified mammalian viruses. Gardner still feels a "small nagging doubt-the remote possibility that it's a strange new type of cat virus." To rule out this possibility, the researchers plan an additional series of laboratory experiments, including attempts to produce viral antiserum from guinea pigs and rabbits. The antiserum could then be used in human cancer tissue to test for the presence of the newly discovered virus...
...unable to determine whether any of these particles could cause cancer; this is what sets the new find apart from earlier ones and makes scientists hopeful of further progress. "If this proves to be a true human virus," says Dr. Robert Huebner of the National Cancer Institute's viral carcinogenesis branch, "it will mean that we're light-years ahead of where we've been. It means we've reached a point that we didn't expect to reach for years...
...their great satisfaction, the experimenters found that such hybridization of the viral and RNA strands had occurred. In contrast, when the researchers tested RNA from cells that had not been exposed to the viruses, hybridization virtually ceased. The implication was clear: the cells were indeed ordering up the essential enzyme. Furthermore, the scientists not only found the enzyme and confirmed that it was chemically active but also determined that the cells passed on their enzyme-making ability when they reproduced themselves...
Unfortunately, a recent development has sent four members of the defensive squad scurrying to and from the infirmary. The strongest attack on the defense this season, a viral infection, has left goalie Shep Messing, and fullbacks Chris Wilmot, Norrie Harrower, and Rick Scott weak from diaherria and head colds...
Equine Epidemic Few diseases are more fear-inspiring than encephalitis, a group of viral ailments that attack the brain and sometimes produce a fatal form of sleeping sickness. Thousands of horses died when an epidemic of Eastern equine encephalitis struck the Eastern U.S. in 1933; thousands more were affected when a similar disease hit the Central U.S. and Canada in 1941. Now, horses throughout the Southwest are threatened by yet another related virus. An epidemic of Venezuelan equine encephalomyelitis (VEE) has been working its way northward from South America since 1969 and has now crossed the border into Texas...
