A U.S. biologist says the accumulation of metals in plants may be a strategy to protect the plants from predators such as prairie dogs. Postdoctoral researcher John Freeman of Colorado State University and colleagues said certain plant species growing on soils with high metal content, such as arsenic, copper, selenium or lead, accumulate large quantities of metals in their leaves and stems. The purpose of that hyperaccumulation isn't fully known, but Freeman said it might increase a plant's...

Higher selenium levels in the blood may worsen prostate cancer in some men who have the disease, U.S. researchers said. Researchers at Dana-Farber Cancer Institute in Boston and the University of California, San Francisco, said a higher risk of more-aggressive prostate cancer was seen in men with a certain genetic variant found in about 75 percent of the prostate cancer patients in the study. In those subjects, having a high level of selenium in the blood was associated with a two-fold...

Researchers say U.S. Food and Drug Administration methods of creating seafood consumption guidelines may not offer reliably accurate food safety assessments. University of North Dakota scientists said that when mercury levels are measured in fish, the levels of the mineral selenium also need to be considered. But since only mercury levels are presently being assessed, FDA evaluations of risk from ocean fish consumption are being overstated, and, conversely, risks from eating fresh water fish...
