Two-thirds of a century after Jane Goodall observed "David Greybeard" break off a twig to fashion a fishing rod for termites, researchers following in her footsteps have found that adult chimpanzees in Senegal literally hand youngsters the tools for learning.

Scientists have found how a protein produced by bacteria disrupts the mechanism that controls flower development in plants, turning reproductive organs into leaf-like structures. These findings shed light on a plant disease that is expected to spread as climate change expands the range of its insect vectors in northern latitudes. They used a synchrotron technique at ESRF, the European Synchrotron in Grenoble, France. The results are an Editor's Pick in the Journal of Biological Chemistry.

Shorebirds are capable of some of the longest migrations on Earth, yet most return year after year to the same area to breed. Coming back has distinct advantages, including knowing the best spots to feed or roost, having information about where predators lurk, and—hopefully—finding last year's partner again.
