Each year, thousands of acres of crops are planted throughout Africa, Asia and Australia only to be laid to waste by a parasitic plant called Striga, also known as witchweed. It is one of the largest challenges to food security in Africa, and a team of scientists led by researchers from the University of Toronto have discovered chemicals and genes that may break Striga’s stranglehold.

Widespread reports of a decline in the population of bees and other flower-visiting animals have aroused fear and speculation that pollination is also likely on the decline. A recent University of Toronto study provides the first long-term evidence of a downward trend in pollination, while also pointing to climate change as a possible contributor. (more…)

ANN ARBOR, Mich. — Shade-grown coffee farms support native bees that help maintain the health of some of the world’s most biodiverse tropical regions, according to a study by a University of Michigan biologist and a colleague at the University of California, Berkeley.
The first before-and-after view of an amphibian die-off has just been published by scientists working at the Smithsonian Tropical Research Institute in Panama. (more…)
It turns out the old saying is right — the nose really does know. And when it comes to sharks, the nostrils are particularly discriminating.
Combined with the ability to detect underwater vibrations, sharks are able to zero in on the location of their prey by smelling in stereo, according to a new study by researchers at the University of South Florida (USF) and Woods Hole Oceanographic Institution (WHOI).
