The pathogen responsible for Sudden Oak Death, a disease that has felled millions of oaks and tanoaks along the Pacific Coast, is evolving, suggesting that movement of infected plants between different quarantined regions should be restricted. The study also revealed that the pathogen got its first toehold in California's forests outside a nursery in Santa Cruz and at Mt. Tamalpais in Marin County.

A critically endangered turtle that previously was thought to be extinct in the wild has been discovered in northern Vietnam. Experts confirmed that they have identified the only known living specimen of a Swinhoe's soft-shell turtle (Rafetus swinhoei) in nature.

Using a lowly bloodless worm, researchers have discovered an important clue to how iron carried in human blood is absorbed and transported into the body. The finding could lead to developing new ways to reduce iron deficiency, the world's number one nutritional disorder.

The scientists were investigating the lifestyle of two early elephants (proboscideans) Moeritherium and Barytherium that lived in the Eocene period, over 37 million years ago. By analysing isotopes in tooth enamel from Moeritherium they were able to deduce that it was very likely a semi-aquatic mammal, spending its days in water eating freshwater plants.'

Winter cover crops provide important ecological functions, but their use in agronomic farming systems remains low. Scientists investigated the potential for winter cereal cover crops to perpetuate themselves through self-seeding, thereby eliminating the cost of planting a cover crop each fall and time constraints between cash crop harvest and the onset of winter. The study found plant establishment through self-seeding was generally accomplished within one week after soybean harvest.
