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.

News that Chinese researchers have succeeded in growing healthy living mice from mouse skin cells takes scientists a significant step closer to human cloning, experts say, and is thus likely to reopen debate about the ethics of such reproductive techniques. The new feat -- in which animals were grown from cells that had been reverted back to their embryonic state -- is technically different from cloning. But the outcome is the same in both cases: a genetically identical copy of the donor animal.

James Symington is experiencing an extreme case of deja vu. The former Halifax, Canada, police officer's partner, Trakr, died in April. But on Wednesday, Symington took home five clones of the German shepherd as the winner of a contest run by a business that does stem-cell research and microengineering. In his career as a search-and-rescue dog, Trakr helped recover more than $1 million in stolen goods and sniffed out the final survivor in the rubble of the World Trade Center after the Sept.

Scientists have created the first genetically modified monkeys that can pass their new genetic attributes to their offspring, a development designed to give researchers new tools for studying human disease, but one that raises a host of thorny ethical questions. In this case, the Japanese researchers added genes that caused the animals to glow green under a fluorescent light and beget offspring with the same spooky ability.

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.

Treatment with genetically modified stem cells helped rats with a paralyzing disease live significantly longer, U.S. researchers said this week. Rats with amyotrophic lateral sclerosis, or Lou Gehrig's disease, that were treated with the gene-engineered stem cells lived 28 days longer than untreated mice, the researchers told a conference. The injection contained adult nerve stem cells that were engineered to release a growth factor called glial cell-line derived neurotrophic factor, or GDNF.

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.
