In the future, if you want to improve your ability to manipulate numbers in your head, you might just plug yourself in. So say researchers who report in the Cell Press journal Current Biology on May 16 on studies of a harmless form of brain stimulation applied to an area known to be important for math ability.

April 25 (Reuters) - Heavy use of the world's most popular herbicide, Roundup, could be linked to a range of health problems and diseases, including Parkinson's, infertility and cancers, according to a new study. The peer-reviewed report, published last week in the scientific journal Entropy, said evidence indicates that residues of "glyphosate," the chief ingredient in Roundup weed killer, which is sprayed over millions of acres of crops, has been found in food. Those residues enhance the damaging effects of other food-borne chemical residues and toxins in the environment to disrupt normal body functions and induce disease, according to the report, authored by Stephanie Seneff, a research scientist at the Massachusetts Institute of Technology, and Anthony Samsel, a retired science consultant from Arthur D. Little, Inc. Samsel is a former private environmental government contractor as well as a member of the Union of Concerned Scientists. "Negative impact on the body is insidious and manifests slowly over time as inflammation damages cellular systems throughout the body," the study says. We "have hit upon something very important that needs to be taken seriously and further investigated," Seneff said. Environmentalists, consumer groups and plant scientists from several countries have warned that heavy use of glyphosate is causing problems for plants, people and animals. The EPA is conducting a standard registration review of glyphosate and has set a deadline of 2015 for determining if glyphosate use should be limited. The study is among many comments submitted to the agency. Monsanto is the developer of both Roundup herbicide and a suite of crops that are genetically altered to withstand being sprayed with the Roundup weed killer. These biotech crops, including corn, soybeans, canola and sugarbeets, are planted on millions of acres in the United States annually.
