The team of Denis Réale, holder of the Canada Research Chair in Behavioural Ecology and Professor in the Department of Biological Sciences at UQAM, recently published some remarkable research findings. Reconstructing the genetic history of a population of mouflons descended from a single pair, the researchers demonstrated that the animals’ genetic diversity increased over time, contrary to what the usual models predict. These results contradict the belief that a population descended from a small number of individuals will exhibit numerous deficiencies and reduced genetic diversity. http://www.video.uqam.ca/kerguelenmouflons

Scientists have long thought that microtubules, part of the microscopic scaffolding that the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome.

A research team has identified a new biological function for a soccer ball-shaped nanoparticle called a buckyball – the ability to block allergic response, setting the stage for the development of new therapies for allergy.

Cornell researchers have discovered that in the battle of the sexes, African electric fish couples not only use specific electrical signals to court but also engage in a sort of dueling "electric duet."

While women may cheat on men for personal reasons, superb starling females appear to stray from their mates for the sake of their chicks, according to recent Cornell research published in the Proceedings of the Royal Society of London B.

Are Asian elk hard-wired to fear the Siberian tigers who stalk them" When wolves disappear from the forest, are moose still afraid of them?

Biomedical engineers at Duke's Pratt School of Engineering have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor’s location.
