Wild birds that are more clever than others at foraging for food have different levels of a neurotransmitter receptor that has been linked with intelligence in humans, according to a study led by McGill University researchers. The findings could provide insight into the evolutionary mechanisms affecting cognitive traits in a range of animals.
The study, published in Science Advances, was conducted by McGill biologists Jean-Nicolas Audet and Louis Lefebvre, in collaboration with researchers from Duke and Harvard universities.
Will the upcoming federal budget deliver and implement the Naylor report’s recommendations to fund and revitalize fundamental science research in Canada?
Martha Crago, Vice-Principal (Research and Innovation) at McGill University, is available to provide reactions in media interviews on Federal budget day on February 27, 2018, and on February 28.
Are Canadians fair or is that just a story we tell ourselves? Can we reason our way to lessened inequality or are violent cataclysms the only levelling power, as Thomas Piketty and Walter Schiedel argue? How do we maintain a sense and an approximation of fairness in our globalizing and polarizing world? Certainly there can be no fairness without tax fairness: tax policy is where we negotiate the relationship between wealth and poverty.
The internal anatomy of our lungs is surprisingly variable, and some of those variations are associated with a greater risk of chronic obstructive pulmonary disease (COPD), a new study led by researchers at McGill University and the Columbia University Irving Medical Center has found.
Team leader Marta Cerruti, using the tools of the Canadian Light Source, has examined the mineralized arteries of genetically modified laboratory mice and found that the pathway in the body that leads to what laypeople call “hardening of the arteries” is not what medical experts previously assumed.
An over-reliance on self-report screening questionnaires, wherein patients essentially define their own condition, in place of diagnostic interviews conducted by a health care professional, has resulted in over-estimation of the prevalence of people with depression in many research studies – often by a factor of two to three times. This is according to a study published in the Canadian Medical Association Journal. The study found that over 75% of recent research on depression prevalence has been based exclusively on patient completed questionnaires.
Frequently encountered in the elderly, Alzheimer’s is considered a neurodegenerative disease, which means that it is accompanied by a significant, progressive loss of neurons and their nerve endings, or synapses. A joint French and Canadian study published in Scientific Reports now challenges this view.
The Geminids meteor showers will peak on the evening of Dec. 13 and continue until early morning Dec. 14. The meteors will be bright and you can see up to 120 meteors an hour stream across the sky. Observers need to go to areas with little light pollution.
