On Nov. 21, McGill’s Barrett Lab hosted a public talk, “Ecology and evolution of aquatic microbiomes: from inland lakes to the Arctic Ocean,” as part of the Conservation, Ecology, Evolution & Behaviour (CEEB) research initiative. In this event, David Walsh, professor in Concordia’s Department of Biology, presented his research on[Read More…]

Exploring the microbiota of human breast milk
Until recently, scientists presumed that breast milk—the primary source of infant nutrition— was microbe-free. However, recent studies have found that breast milk contains a healthy dose of good bacteria. These microbes originate from the mother’s gut microbiota—the harmless micro-organisms that colonize the human digestive system. The microbiome performs diverse functions[Read More…]
The gut microbiome in disease and health
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[Read More…]
Small but mighty: Arctic bacteria are capable of cleaning up oil spills
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[Read More…]
Fantastic alien microbes and how to find them
The 2015 discovery of water on Mars, an essential for life on Earth, sparked theories of thriving Martian life. Ideas of interstellar travel to find extracellular beings were suddenly within reach. The second Montreal Space Symposium on Oct. 18 to 19, offered a forum for the future of space exploration,[Read More…]
A story of community: Trees, fungi, and microbes work hand-in-hand
Researchers at McGill, in partnership with the Université de Montréal’s (UdeM) Plant Biology Research Institute, have discovered a hidden ecosystem that works to clean polluted land. The project consisted of a collaboration between Nicholas Brereton, a research fellow at UdeM’s Plant Biology Research Institute and senior author of the study,[Read More…]
McGill labs find new ways to target resistant bacteria
In 1945, Alexander Fleming, made famous for his discovery of penicillin, warned that excessive antibiotic use would likely result in bacteria developing resistance. The term is often in the headlines, but what exactly is antibiotic resistance? It is generally defined as microorganisms developing the ability to somehow prevent the intended[Read More…]
