Argentine scientist who challenged Monsanto dies
Dr. Andres Carrasco, an Argentine neuroscientist who challenged pesticide regulators to re-examine one of the world's most widely used weed killers, has died. He was 67.

 

Argentina's national science council announced Carrasco's death on Saturday. He had been in declining health.

 

Carrasco, a molecular biologist at the University of Buenos Aires and past-president of Argentina's CONICET science council, was a widely published expert in embryonic development whose work focused on how neurotransmitters affect genetic expression in vertebrates. But none of his research generated as much controversy as his 2010 study on glyphosate, which became a major public relations challenge for the St. Louis, Missouri-based Monsanto Company. (AP)
