In a potential breakthrough in cancer research, scientists at the University of Pennsylvania have genetically engineered patients' T cells — a type of white blood cell — to attack cancer cells in advanced cases of a common type of leukemia. Two of the three patients who received doses of the designer T cells in a clinical trial have remained cancer-free for more than a year, the researchers said. Experts not connected with the trial said the feat was important because it suggested that T cells could be tweaked to kill a range of cancers, including ones of the blood, breast and colon.

A group of senators has asked the Food and Drug Administration to abandon its approval process of genetically engineered salmon as food, threatening to push legislation to strip the FDA's funding to study the fish if the agency does not comply. Eight senators sent a letter dated July 15 to the FDA asking it to "immediately cease" consideration of such salmon, a product brought before the agency by AquaBounty Technologies 15 years ago. AquaBounty's proposal calls for the embryos of the fish to be sterilized in Canada before being shipped to Panama, where the males would be exposed to estrogen and sex-reversed.

Activists rejoiced last week when a hard-fought battle over international standards for labeling genetically modified food came to an end — finally — after decades of debate. But the agreement, which many say opens the door for labels to be placed on such foods, will probably have little effect on food labels in the U.S. for the foreseeable future. And that could be a good thing, some scientists said. "The public gets bogged down on whether [crops are] genetically engineered or not. We think that's a distraction," said Pamela Ronald, a professor of plant pathology at UC Davis.

Leather, tulle and silk may be the stuff of runway dreams, but when it comes to most U.S. apparel, cotton is king. Almost 75% of clothing sold in the U.S. contains at least some of the tufty fiber, according to the 2010 Cotton Inc. Retail Monitor, a survey of mass retailers. Farmers in this country will grow 8.16 billion pounds of cotton during the current growing season. Add China, India and the 100-plus other countries that cultivate cotton, and the yield is 62 billion pounds produced annually worldwide.

Cancer treatments, such as radiation and chemotherapy, are more shotgun-scattered than precision-targeted. They damage bystanding healthy cells as they attack the tumor tissue, causing nasty side effects. Scientists would like to focus these therapies more narrowly on the cancer cells alone, and researchers in Toronto have come up with a new strategy. With a flick of a genetic switch, they've made cancer cells ultra-sensitive to radiation, thus killing tumors that normally withstand the treatment.

Soybeans, corn, cotton and canola ? most of the acres planted in these crops in the United States are genetically altered. "Transgenic" seeds can save farmers time and reduce the use of some insecticides, but herbicide use is higher, and respected experts argue that some genetically engineered crops may also pose serious health and environmental risks. Also, the benefits of genetically engineered crops may be overstated. We don't have the complete picture. That's no accident. Multibillion-dollar agricultural corporations, including Monsanto and Syngenta, have restricted independent research on their genetically engineered crops.
