Washington Post: On 30 June more than 100 Nobel laureates, including 25 physics awardees, released a letter that called for the environmental activism group Greenpeace to end its opposition to the use of genetically modified organisms (GMOs) in agriculture. The letter primarily focused on Golden Rice, a form of rice that produces high levels of beta-carotene, a precursor of vitamin A. Golden Rice was developed as a potential crop for areas where the populations suffer from vitamin A deficiency. The letter says that Greenpeace has driven the resistance to the commercialization of Golden Rice and to GMOs in general, despite the lack of evidence that engineered crops are harmful. The signature campaign was organized by Richard Roberts of New England Biolabs, who shared with Phillip Sharp the 1993 Nobel Prize in Physiology or Medicine for the discovery of genetic sequences called introns.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
