Genetic Engineering

The notion that the hot dog should be redesigned inspires a variation on the mad-scientist-movie line: "Man was not meant to tamper in God's domain." Or, in this case, Oscar Mayer's. Yet the American Academy of Pediatrics is proposing that the wiener (and other products frequently consumed by children) be reshaped as a way of preventing toddlers from choking. The proposal doesn't sit well with an interest group we didn't even know existed, the National Hot Dog & Sausage Council.

Part animal, part plant! This may sound like a tabloid headline, but scientists say that a green sea slug has managed to incorporate enough algae parts to easily live off of sunlight, just as a plant does. Scientists already knew that a few slugs could eat algae but save the algae's chloroplasts from digestion and feed off of their energy. Chloroplasts are where the photosynthesis process of turning light into energy occurs. But this was not a self-sustaining system, since most slugs cannot make their own chlorophyll, a green pigment that fuels the chloroplasts.

Fast-growing salmon. Pork containing heart-healthy omega-3 fatty acids. These are two examples of products you might see in your local supermarket soon -- animals developed not through conventional breeding but through genetic engineering. On Jan. 15, the U.S. Food and Drug Administration decided how it will regulate genetically engineered animals, for the first time paving the way for such animals or their products to be sold as food and medicine.

They have four legs, fuzzy faces and udders full of milk. To the uninitiated, they look like dairy goats. To GTC Biotherapeutics Inc., they're cutting-edge drug-making machines. The goats being raised on a farm in central Massachusetts are genetically engineered to make a human protein in their milk that prevents dangerous blood clots from forming. The company extracts the protein and turns it into a medicine that fights strokes, pulmonary embolisms and other life-threatening conditions.

The Food and Drug Administration on Thursday opened the way for a bevy of genetically engineered salmon, cows and other animals to leap from the laboratory to the marketplace, unveiling an approval process that would treat the modified creatures like drugs.

The Food and Drug Administration will release regulatory guidelines today governing genetic engineering of animals for food, drugs or medical devices. The FDA's regulatory control of animals will be considerably stronger than its oversight of genetically engineered plants and microorganisms.

Howard L. Bachrach, the virologist who purified the polio and foot-and-mouth disease viruses and was the first to use genetic engineering to produce a vaccine, died June 26 in Atlantis, Fla. He was 88 and had been suffering from heart disease, according to his daughter, Eve. His work on purification of the polio virus made possible the development of the vaccine against the disease by Dr.

Food regulators have been swamped with comments from consumers weighing in on a proposal by the Food and Drug Administration to allow food made from cloned animals to be sold to the public. More than 30,500 comments on the proposal have been received by the agency, FDA spokeswoman Julie Zawisza said. The agency is still reviewing the issue and isn't ready to say when it will announce a final rule on cloned livestock, she said. cutline> ##na-dna4#ju34rxnc#PH186P83#Tim Sharp Associated Press## Charles Chatman, center, with attorney Jeff Blackburn and aunt Ethel Bradley in Dallas, spent nearly 27 years in prison.

Stem cells taken from Duchenne muscular dystrophy patients and genetically modified eased symptoms of the disease in mice, strengthening their muscles and allowing them to run longer on a treadmill, researchers reported Wednesday in the journal Cell Stem Cell. The patients have a nonfunctional form of a protein called dystrophin. Researchers modified the muscle cells from the patients to produce a shortened but still effective form of dystrophin.
