Overfishing of small species causes jellyfish curse
Marine biologists say they have proof that excessive trawling of small fish species leads to proliferation of jellyfish, a worsening phenomenon whose causes have been unclear.
Studies find wild bees and insects essential to food security
Wild pollinators – primarily wild bees, flies, and other insects – are at least as important, and often more efficient, at pollinating agricultural crops than domestic honey bee colonies, according to ...
Scientists improve transgenic 'Enviropigs'
A research team at the University of Guelph has developed a new line of transgenic "Enviropigs." The new line of pigs is called the Cassie line, and it is known for passing genes on more reliably. The results of this project ...

Why are storks changing their migratory patterns? New project launched
In folklore, storks' strong white wings would carry babies to parents around the world. But since the mid 1980s increasing numbers of storks have stopped their annual migration from Northern Europe to Africa ...
How much protection is enough?

Superbugs may have a soft spot, after all
The overuse of antibiotics has created strains of bacteria resistant to medication, making the diseases they cause difficult to treat, or even deadly. But now a research team at the University of Rochester has identified ...
