...Genomic Research (TIGR), where in 1994 he upped the gene-sequencing ante to a new level. At the urging of medicine Nobelist Hamilton Smith, now a Celera scientist, Venter decided to use a technique called shotgunning to sequence the entire genome of a living organism, the H. influenzae bacterium (a bug that causes ear and respiratory infections...
SIDS RISKS Researchers from the Royal Manchester Infirmary have discovered a possible link between sudden infant death syndrome and a common bacterium that is transmitted orally. Babies who died from SIDS were found to have a much higher rate of H. pylori infection than other children. In adults, the bacterium is usually linked to stomach ulcers, but researchers theorize that the bug could be passed to infants by parents' kissing them or caretakers' testing the temperature of a bottle by licking the nipple...
PREGNANT PAUSE Doctors in Puerto Rico report that severe morning sickness may be linked to a bacterium known as H. pylori, the same stomach bug that causes ulcers. They found that 89% of pregnant women with intense nausea tested positive for the bacterium, whereas less than 10% of those who never felt sick came up positive. Taking antibiotics during pregnancy is generally a no-no, but women might consider getting screened for H. pylori before trying to conceive...
...plates. Sure enough, early last week Genetically Engineered Food Alert, a consumer and environmental group, reported that traces of DNA from GM corn not approved for human consumption had been discovered in Taco Bell's tacos. The corn, known as StarLink, contains a gene from a bacterium that makes the corn deadly to corn borers but not to cows. It was approved for use as cattle feed but not for human consumption, for fear it could trigger allergic reactions...
...Scripps Research Institute, where he starts his day by 5 a.m., uses combinatorial methods to study everything from nanotechnology to organ regeneration. His scientists have invented 80 new amino acids and used them to make proteins seen nowhere in nature, and they are trying to create an artificial bacterium with two extra bases in its DNA and five unnatural amino acids in its proteins. "The question is," says Schultz, "Why are there only four bases in our DNA and only 20 amino acids in our proteins? What would life look like if God had worked on the seventh...
