An elephant never forgets, as the saying goes. In fact, there is evidence that proboscideans still remember the waterholes they once visited decades later. They also often recognize fellow elephants that they have not encountered for a long time. But.....»»
Asteroid that wiped out the dinosaurs may have led to the invention of "ant agriculture"
The event that wiped out the dinosaurs wasn't all bad. The low-light environment caused by the meteor impact some 66 million years ago favored the spread of fungi that feed on organic matter, which was abundant at the time as plants and animals were.....»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
