In the 1960s, University of Pennsylvania biologist Dan Janzen re-described what has become a classic example of biological mutualism: the relationship between acacia-ants and ant-acacia trees. The acacia trees produce specialized structures to shelter and feed the ant colony, and the ants, in turn, defend the tree against herbivores. »
Scientists say they have almost eradicated populations of the world’s most invasive mosquito species from two test sites in China using a novel two-pronged approach which renders the insects infertile. »
Hyperglycemia, or high levels of glucose, is common in patients with acute ischemic stroke and is associated with worse outcomes compared to normal blood sugar levels. Stroke experts have debated whether intensive glucose management after acute ischemic stroke leads to better outcomes but a new study in JAMA finds that aggressive methods are not better than standard approaches. »
