A new U.S. Geological Survey laboratory study of two potentially toxic types of freshwater cyanobacteria, or blue-green algae, found that exposure to salty water can damage the cyanobacteria cells’ walls, causing them to release their toxins into the water.

Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species’ inability to resist a pervasive and deadly disease. Their finding, published in the Proceedings of the National Academy of Sciences, could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.

A new type of blow fly spotted in Indiana points to shifting species populations due to climate change. Researchers at IUPUI have observed the first evidence of Lucilia cuprina in Indiana, an insect previously known to populate southern states from Virginia to California.

A new study has shown that eating vegetable nitrates, found mainly in green leafy vegetables and beetroot, could help reduce your risk of developing early-stage age-related macular degeneration (AMD).

Adding highly refined fiber to processed foods could have negative effects on human health, such as promoting liver cancer, according to a new study by researchers at Georgia State University and the University of Toledo.
