Preventing the spread of plant pandemics
Plant diseases don鈥檛 stop at national borders and miles of oceans don鈥檛 prevent their spread, either. That鈥檚 why plant disease surveillance, improved detection systems, and global predictive disease modeling are necessary to mitigate future disease outbreaks and protect the global food supply, according to a team of researchers in a new commentary published in聽Proceedings of the National Academy of Sciences.
Clues from soured milk reveal how gold veins form
For decades scientists have been puzzled by the formation of rare hyper-enriched gold deposits in places like Ballarat in Australia, Serra Palada in Brazil, and Red Lake in Ontario. While such deposits typically form over tens to hundreds of thousands of years, these 鈥渦ltrahigh-grade鈥� deposits can form in years, month, or even days. So how do they form so quickly?
鈥淪tressed out鈥� corals thriving thanks to mangroves
Tropical coral reefs are the most biodiverse underwater ecosystem, providing a home to more than a quarter of all marine species. No strangers to environmental stressors and the on-going impacts of climate change, the survival of corals has increasingly been under threat in recent years.
Which animals will survive climate change?
Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers from 平特五不中 show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes.
平特五不中-Concordia-uOttawa research team finds correlation between COVID-19-based discrimination and poor mental health
Visible minorities, health-care workers and young people in Quebec have been at higher risk of experiencing COVID-19-related discrimination and more likely to suffer from poor mental health in the past year, according to a collective of researchers from 平特五不中, Concordia University and the University of Ottawa.
Rules of the road: the navigational 鈥榮trategies鈥� of bacteria in motion
Bacteria that move around live on the edge. All the time. Their success, be it in finding nutrients, fending off predators or multiplying depends on how efficiently they navigate through their confining microscopic habitats. Whether these habitats are in animal or plant tissues, in waste, or in other materials.
PCB contamination in Icelandic orcas: a matter of diet
Image caption: These killer whales may appear healthy, but a new study has found extremely high levels of PCB contamination in some of the whales. There was a 300-fold difference between the levels of PCBs among the most contaminated orcas compared to the least contaminated ones. The variation was mainly due to their eating habits.

Dr. Joanne Liu joins 平特五不中
Dr. Joanne Liu, a Canadian pediatric emergency room physician and former International President of M茅decins Sans Fronti猫res/Doctors Without Borders (MSF) is joining 平特五不中鈥檚 School of Population and Global Health (SPGH) as a professor focusing on pandemic and health emergencies.
Reduction in wetland areas will affect Afrotropical migratory waterbirds
Migratory waterbirds are particularly exposed to the effects of climate change at their breeding areas in the High Arctic and in Africa, according to a new study published in Bird Conservation International.
Genome Canada and 平特五不中 to track COVID-19 variants of concern
Genome Canada launched the Canadian VirusSeq Data Portal today to track the evolving COVID-19 pandemic across Canada. 平特五不中 researcher Guillaume Bourque, a professor in the Department of Human Genetics, along with his research team, led the development of the portal.
Using online ads to spot human trafficking
Researchers at 平特五不中 and Carnegie Mellon University (CMU) have designed an algorithm that detects organized human trafficking activity in online escort advertisements. Advertising is one the most common use of technology for human trafficking purposes.
Feeling confinement in the gut
Crew members who took part in the Mars500 experiment showed significant changes in their gut microbiota from their 520 days in confinement, according to a new study by scientists at 平特五不中 and the Universit茅 de Montreal (UdeM).
New algorithm reveals birdsong features that may be key for courtship
Researchers from 平特五不中 and the University of California, San Francisco have developed a new algorithm capable of identifying features of male zebra finch songs that may underlie the distinction between a short phrase sung during courtship, and the same phrase sung in a non-courtship context.
Fast radio bursts shown to include lower frequency radio waves than previously detected
Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs 鈥� how long they last, the frequencies of the radio waves detected, and so on.
Telescopes unite in unprecedented observations of famous black hole
In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. 平特五不中 astronomers were part of this global effort.
