People opposed to genetically modified organisms often insist that the plants are no good for anyone except the companies, like Monsanto Co., that sell GMO seeds. A new study may force them to come to terms with the idea that GM crops can benefit regular people too -- even farmers in developing countries like India. The study , published this week in the journal PLOS ONE, tracked the fortunes of 533 cotton farms in India over eight years. These farming families were poor -- on average, family members consumed no more than $500 worth of goods each year.

My grandmother, who raised some great family dogs, always said that mutts made the smartest and healthiest pets. A new study of the medical records of more than 90,000 purebred and mixed-breed dogs suggests that there is some truth to Grandma's theories on canine health - but only to a point. When it comes to genetic disorders in dogs, a Maltese isn't always more likely to suffer than a mongrel. Prevalence “among purebred and mixed-breed dogs depends on the specific condition,” said UC Davis animal physiologist Anita Oberbauer, lead author of a report published Tuesday in the online edition of the Journal of the American Veterinary Medical Assn.

The Food and Drug Administration on Wednesday announced its approval of two new drugs and a diagnostic test that can be used to treat advanced or inoperable melanoma, the most dangerous form of skin disease. Advanced melanoma has joined a wide range of cancers for which treatment is increasingly personalized, with genomic diagnostics and targeted drugs that promise greater effectiveness than old-fashioned chemotherapy. The newly approved drugs , dabrafenib (to be marketed as Tafinlar)

Hundreds of protesters took to the streets in downtown Los Angeles on Saturday as part of a global series of marches against seed giant Monsanto Co. and genetically modified foods. Organizers said the March Against Monsanto demonstrations were being held in some 300 cities in more than 44 countries this weekend. The event -- a social media-generated call to action against genetically modified foods and the multinational corporations that produce them -- marked the first such global, unified protest for this cause, organizers said.

The movement to force the labeling of genetically engineered food is gaining momentum. In November 2012, an initiative to require the labels in California was on the ballot; it was defeated. Now, federal legislation carried by Sen. Barbara Boxer (D-Calif.) would mandate labeling most bioengineered food nationwide. Yet the movement's argument is weakened by the lack of evidence that inserting fragments of DNA into crops harms our health. Pro-labeling activists - who also tend to be anti-Monsanto activists - point to polls finding that most Americans want the information labeled.

Here's a scientific finding that may knock you off your feet: At least 80 types of fungi reside on a typical person's heel, along with 60 between the toes and 40 on the toenail. Altogether, the feet are home to more than 100 types of fungus, more than any other area of the human body, according to a study published Wednesday by the journal Nature. And that fungal fellowship is in constant motion as we walk through life. It may sound icky, but many of the fungi on our skin serve a very useful purpose, said study leader Julie Segre, a geneticist at the National Human Genome Research Institute in Bethesda, Md. "One of the major functions of healthy fungi is to prevent pathogenic fungi from adhering to our skin," where they can cause athlete's foot, plantar warts and stubborn toenail infections, she said.

For the first time, scientists have created human embryos that are genetic copies of living people and used them to make stem cells - a feat that paves the way for treating a range of diseases with personalized body tissues but also ignites fears of human cloning. If replicated in other labs, the methods detailed Wednesday in the journal Cell would allow researchers to fashion human embryonic stem cells that are custom-made for patients with Alzheimer's disease, diabetes and other health problems.

WASHINGTON - Monsanto Co. and other companies that patent seeds may prohibit farmers from growing a second crop from their genetically modified seeds, the Supreme Court ruled unanimously. The closely watched decision was a clear victory for agribusiness giants and their biotechnological innovations, which have increased crop yields. But it was a setback for the many disgruntled farmers who have complained about the high cost of these miracle seeds. By a 9-0 vote, the justices decided the patent for a specialized seed outlives the first planting.

By opting for surgery to remove her breasts while they were still healthy, Angelina Jolie joined a growing number of women who have used genetic testing to take control of their health. Here are answers to some common questions about how DNA influences breast cancer risk and what women can do about it. What genes are involved in breast cancer? The two primary ones are known as BRCA1 and BRCA2. Hundreds of variants of these genes have been found that make a woman - or a man - more likely to develop breast cancer.

A new federal report has found that the nation's honeybee decline, which threatens up to $30 billion worth of agriculture production, is being caused by several factors, including disease, parasites and poor genetics. After colony collapse disorder began spreading in 2006, federal officials convened a group of researchers to study the phenomenon. Thursday's report by the Department of Agriculture and the Environmental Protection Agency found several causes for the honeybee decline.
