University of Florida scientists have developed new technology to more precisely target radiation beams at cancerous tumors of the body's internal organs, an advance they hope will improve cure rates and result in fewer side effects.

DDT insecticide increases risk of preterm birth
Exposure of pregnant women to DDT, the insecticide effective in malaria control, is strongly linked to an increase in preterm birth, conclude authors of a study in this week's issue of THE LANCET.
