There are thousands of different bacterial species living inside our intestines. This environment, called the gut microbiome, provides the body with key vitamins and ensures a healthy immune system. The composition of the gut microbiome is key: Dysbiosis, a condition that occurs when ‘bad’ bacteria take over the gut, is […]
In the past decades, the field of neuroscience has made astounding progress toward unravelling the intricacies of the human brain, but much of how it functions remains terra incognita. Adrien Peyrache, a researcher at the Montreal Neurological Institute (MNI) and Canada Research Chair in systems neuroscience, studies how brain structures […]
According to some estimates, there may be up to five million oil and gas wells in Canada and the United States. In Alberta alone, more than 600,000 wells have been drilled—one for every seven people in the province. The consequences of the extraction, refinement, and use of petroleum is well […]
Substance use is a global issue, affecting more than 235 million people annually. As public awareness of the opioid epidemic grows, up-to-date information on drug use remains critical in addressing these health concerns. The importance of such data led to a study that was published in the journal Addiction in October, […]
Comparing animals of various sizes has historically been a challenge for biologists. From simple observation, an elephant could not be more different than a mouse. Yet, a universal underlying principle concurrently governs them both. Scaling laws—derived mathematical models that compare an organism’s key life traits to its body mass—present an […]
While thousands of sports-related concussions occur each year in Canada, the mechanisms behind the injury are still shrouded in mystery. Scientists use the word ‘concussion’ to describe the symptoms of damage inflicted on the brain, but they are still working to uncover the underpinnings at the cellular level. Concussions occur […]
Currently, the United Nations (UN) estimates that there are approximately 7.7 billion people in the world, a number that is expected to reach 10 billion by 2050. Moreover, human populations are becoming more dense: 68 per cent of people are expected to live in urban centres by 2050. As these […]
Rarely does the title of a scientific study live up to the aspirations of its authors. The BIG Project, however, is an exception. BIG, which stands for the Biotic Interaction Gradients experiment, is the first endeavour of its kind to explain one of Charles Darwin’s oldest theories: Species interactions play […]
Historically impassable, the ice cover of the Northwest Passage along Canada’s Arctic coast has thinned over the past few years, piquing the interest of the shipping and luxury cruise industries. This thinning, along with Arctic drilling, makes the legendary frozen passage particularly susceptible to oil and fuel spills. To combat […]
Scientists believe that planets outside of the solar system capable of supporting life should look a lot like Earth. The theory posits that if the chemical components comprising Earth’s atmosphere can be found in that of distant planets, those worlds could harbour similar carbon-based life-forms. This summer, two McGill University […]
