Gamaliel López Candanosa and Gerardo Paredes Pérez, two journalists with Mexico's national network TV Azteca in Nuevo León, have been "disapeared" for the last four days, the network says in a May 14 statement. "The atmosphere of violence generated in recent months in the metropolitan area of Monterrey has provoked various speculations about their whereabouts, but nothing is confirmed," said TV Azteca's regional director Luis Padua at a press conference. "The only thing which is certain is that the reporters have not arrived at their houses or shown up at work." Gamaliel López generally covered urban development issues, but in July 2006 he was assigned to cover the finding in Monterrey of a severed human head with a threatening note from a narco gang.

According to government figures, nearly 2,000 current and former employees of two sugar mills in the Chichigalpa region of northwestern Nicaragua suffer from chronic renal insufficiency (CRI), a fatal kidney disease. While the cause remains a mystery, a workers group puts the death toll at more than 560 employees of one of the mills alone over the past 30 years. Residents point to the chemicals used in sugar-cane fields at the San Antonio and Monte Rosa mills, which produce most of Nicaragua's sugar exported to the US. The mills deny responsibity, and say workers who sued the companies presented no scientific evidence.
