Faced with the sharp shifts of climate change and continuous human expansion, animals must adapt to survive—an ability that depends largely on a species’ genetic diversity. Professor Ioannis Ragoussis, head of genome sciences at the McGill Genome Centre, is studying this diversity by sequencing the genome of species native to[Read More…]

Projecting global temperatures more accurately
Estimating global climate change with any degree of accuracy is no easy feat. Although climate models all agree that global temperatures are increasing, the rate and extent to which predictions differ leaves us with uncertainty. For example, it is unclear when the Earth will surpass key temperature thresholds, such as[Read More…]
Getting to the roots of hair loss
Hair loss and hair shedding are very common in times of stress and can affect anyone—even those who have no family history of either condition. Apart from genetics, other factors, such as medication, stress, birth control, or lack of sleep can kill the stem cells inside hair follicles. Stem cells[Read More…]
Hot girl summer eclipsed by Hot Exo-Jupiter
Roughly equal to the mass of 12 Jupiters, exoplanet XO-3b was the subject of a recent study led by Lisa Dang, a PhD student studying short-period exoplanets and their atmospheres at McGill. Exoplanet XO-3b is classified as a “Hot Jupiter,” a planet with physical properties similar to Jupiter that has[Read More…]
Researchers pinpoint a gene variant that could provide increased protection against severe COVID-19
It is well known that a person’s genome can predispose them to certain diseases—but can also provide increased protection against other diseases. Geneticists have recently observed that a particular haplotype, a chunk of DNA that encodes several genes, is protective in nature against COVID-19 and results in a reduced risk[Read More…]
Millipedes: A fascinating gateway into the world of entomology
It’s safe to say that most people are familiar with the creepy-crawly known as the millipede; from scuttling out of the dirt in your garden to gnawing on leaves in your attic, millipedes are a common sighting. Many creatures, from spiders to snakes—and even some species of butterfly—evoke fear due[Read More…]
The glowing DNA that can act as protein motion sensors
In the methodical world of scientific research, there is irony to be found in serendipitous stories of discovery. More often than expected, a scientist’s day in the lab is filled with more head-scratching than “eureka” moments. It is in these moments that a curious scientist would dig deeper, even in[Read More…]
How gene mutations affect vitamin B12 deficiency
In recent years, vitamin supplements have become all the rage, with an increasing number of supplements claiming to clear your skin, promote hair growth, and even increase your IQ. Unrealistic advertisements aside, vitamins are in fact quite important. Our bodies need vitamins in small amounts to be able to grow[Read More…]
Demystifying ARSACS, a rare neurodegenerative disease concentrated in Quebec
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare neurodegenerative disease first identified in the Charlevoix-Saguenay region of Quebec. The disease affects muscle control, making a range of activities, from swallowing to speaking to walking, more difficult. Brenda Toscano Marquez, a postdoctoral researcher, and Alanna Watt, a biology professor[Read More…]
ROAAr symposium delves into the complicated relationships between scientists
The science behind friendship and how it develops between people has been a longstanding object of study. However, much less research has looked into the friendships between scientists themselves. The Rare & Special Collections, Osler, Art, and Archives (ROAAr) branch of the McGill Library held a symposium on Jan. 20[Read More…]
