...heart attack; in Oxford. Though penicillin was discovered by Fleming in 1928, the mold was considered little more than a biological curiosity for a decade until the Australia-born Florey and a team of Oxford researchers reduced it to a pure, yellowish powder that destroyed all kinds of bacteria, saving thousands of lives during World War II and untold millions since...
There is no doubt that chloramphenicol, better known by Parke, Davis & Co.'s trade name of Chloromycetin, is a potent and valuable antibiotic. That has been clear since 1947, when it was found to kill a wider variety of bacteria than penicillin or other early antibiotics. Better yet, it was one of the first drugs to show activity against some odd ball microbes called rickettsiae. But Chloromycetin soon showed another side of its character: a few patients developed a severe anemia after taking it, and by 1952 it was clear that some of these patients had died...
Plastic tunnels. To guard against moon viruses and bacteria, NASA will not allow the astronauts to open the Apollo hatch until a plastic tunnel has been extended to the spacecraft from a 35-ft., hermetically sealed van placed near by on the carrier deck. Carrying 50 Ibs. of lunar rock and soil samples in steel vacuum cases, they will walk through the tunnel into the van. There, in the company of a doctor and an engineer, they will be completely isolated from the outside world. When the carrier reaches a U.S. port, the van will be flown intact...
Last week scientists moved a step closer to making the dream possible. In Palo Alto, two biochemists at the Stanford University School of Medicine reported that they had successfully synthesized a virus that could both infect bacteria and reproduce itself...
Sinsheimer placed the synthetic DNA molecules into laboratory dishes filled with Phi X's natural victim, E. coli bacteria, which are common intestinal microbes. Invading the E. coli cells, the DNA molecules directed them to produce hundreds of Phi X viruses, each complete with its protein coat. Eventually the invaded cells ruptured under their burden of viruses, killing the bacteria and releasing the viruses to infect other cells. The progeny of the synthetic DNA molecules were not only biologically active but could not be distinguished from natural Phi X viruses...
