Postpartum depression study shows gene behavior differs by environment
A recently released paper in the Proceedings of the National Academy of Sciences (PNAS), “The Role of Mother’s Genes and Environment in Postpartum Depression,” explores the interplay between genes and environment when determining whether a mother is at high or low risk for postpartum depression.
End native versus alien wars: Expert
It is time to drop the alien versus native species dichotomy in conservation, according to a group of eminent scientists concerned with the restoration of ecosystems around the world.
Keeping score helps asthma sufferers breathe a sigh of relief
Seven per cent of adults and 14 per cent of Canadian children have a hard time breathing because of asthma. Brian Rowe, in the Faculty of Medicine & Dentistry at the University of Alberta, is working towards making life easier for both asthma patients and emergency physicians who treat them.
Adjustable valves gave ancient plants the edge
Controlling water loss is an important ability for modern land plants as it helps them thrive in changing environments. New research from the University of Bristol, published today in the journal Current Biology, shows that water conserving innovations occurred very early in plants’ evolutionary history.
Physicists hit on mathematical description of superfluid dynamics
It has been 100 years since the discovery of superconductivity, a state achieved when mercury was cooled, with the help of liquid helium, to nearly the coldest temperature achievable to form a superfluid that provides no resistance to electrons as they flow through it.
