Study shows that a more diverse environment modifies their immune systems and lungs, offering a complementary solution for biomedical research Recreating more natural living conditions for laboratory mice is the goal of Sébastien Hébert, professor in the Faculty of Medicine and affiliated researcher at the Centre de recherche du CHU de Québec - Université Laval.

By comparing data from 1995 and 2021, a team has found that the typical characteristics of southern lakes are now found tens of kilometers further north In 25 years of climate change, how have northern lakes changed? This question motivated a group from the Faculty of Forestry, Geography and Geomatics, affiliated with the Centre for Northern Studies, to set out for James Bay and Hudson Bay in 2021, following an initial expedition in 1995.

The nasally-administered vaccine currently under development could protect children aged 6 months to 5 years against bronchiolitis and pneumonia Human metapneumovirus and respiratory syncytial virus (RSV) cause numerous cases of bronchiolitis and pneumonia in children aged 6 months to 5 years every year.

Research team develops new drug to block antibodies involved in multiple sclerosis-like disease A study published today in the journal PNAS shows that it may be possible to slow the progression of certain autoimmune diseases using drugs that interfere with the antibodies responsible for these pathologies.

An international team discovers three markers that can be used at diagnosis to determine the risk of systemic lupus progressing to a severe form of the disease An international team, led by Paul R. Fortin of Laval University, has identified three markers that can be used to determine, at the time of diagnosis, the risk of lupus developing into a severe form of the disease.

This type of information leads more people to believe that an alcoholic product is not harmful to their health Are you concerned that your alcohol consumption is damaging your health, and believe that an alcoholic beverage with a nutrition facts panel is a better choice than one without?

A study suggests that it may be possible to alleviate this autoimmune disease by preventing platelets from binding to white blood cells Certain autoimmune diseases such as rheumatoid arthritis and lupus could be alleviated, or even cured, by preventing blood platelets from binding to immune system cells.

This herbicide is said to have sub-lethal effects that fly under the radar of ecotoxicological studies A study just published in Scientific Reports indicates that the glyphosate-based herbicide sold under the trade name Roundup does not adversely affect the survival of bumblebees. On the other hand, this product is said to substantially reduce male fertility, which could have repercussions on colony size and, ultimately, on the fertilization of plants that depend on this native pollinator.

This indicator would enable us to quickly identify elderly people at risk of frequent emergency room visits and death The number of medications taken by the elderly is constantly on the rise, and we

Laval University study reveals role of nervous system cell metabolism, combined with inflammation, in ALS-related neuronal degeneration What if amyotrophic lateral sclerosis (ALS) was also a metabolic disease? That's the question raised by a research team led by Chantelle Sephton, professor at Université Laval's Faculty of Medicine and researcher at the CERVO research center.

This new type of panel offers ecological and economic advantages over traditional gypsum panels Would you trust a drywall panel in which gypsum has been replaced by earth and wood fibers? Chances are you'd greet the idea with a certain amount of skepticism, but a study published by two Laval University researchers in the journal Construction and Building Materials suggests that your distrust is unfounded.

The tool, which can be used on an iPad, could help determine whether athletes are ready to return to play A team from Université Laval has developed a tool that could help determine whether athletes who have suffered a concussion are ready to return to the game. Details of their work have just been published in the Journal of Clinical and Experimental Neuropsychology .

Workplace tension and effort-recognition imbalance create chronic stress leading to diseases such as angina pectoris and myocardial infarction If further proof were needed of the damaging effects of psychosocial stressors at work on the health of white-collar workers, it has just been provided by a study published in JACC: Advances , a scientific journal of the American College of Cardiology.

A biofilter made from pumpkin peels could capture almost 100% of the lead present in water contaminated by this heavy metal The millions of pumpkins that need to be disposed of the day after Halloween could have a useful second life for the environment. Indeed, a study published by a team from Laval University in the International Journal of Environmental Science and Technology suggests that pumpkin peel - like that of three other fruits - could provide valuable environmental services thanks to its ability to capture heavy metals such as lead.

This receptor is involved in communication between the brain and liver cells Fatty liver disease, a condition that affects around 20% of adult Canadians, begins with a simple accumulation of fat in the liver. This condition may remain asymptomatic or, for unknown reasons, evolve into an inflammatory state that may lead to fibrosis, cirrhosis or liver cancer.

A study conducted by Université Laval highlights the effects of global warming on freshwater reserves and underscores the urgent need for action to preserve them Algae growth has been accelerating in Canadian lakes since the 1960s. A research team co-led by Université Laval and McGill University reveals that this proliferation is 7 times faster than in previous decades.

The zebrafish offers new insights into the formation of neural networks in the human brain and pathologies such as bipolar disorder and schizophrenia The zebrafish, a distant cousin of the common carp found in Quebec, is a small fish about 5 cm long, native to South Asia. It doesn't use its brain to plan the week's meals or its family's annual vacation, to balance its personal life and professional obligations, to interpret a piece of music on the piano or to solve complex problems requiring elaborate abstract thought.

A new website offers video capsules and popular texts to inform the general public about the scientifically recognized benefits of playing and listening to music You don't have to be a violin virtuoso or a guitarist of the calibre of Jimi Hendrix to enjoy the benefits of music. Every amateur musician benefits from playing an instrument, even if it's just a few notes or a wooden spoon.

The prevalence of the four main types of this virus is less than 1% in young Quebecers aged 16 to 20 who have not received the vaccine. Less than 20 years after its introduction in Quebec, the human papillomavirus (HPV) vaccination program is so effective that even unvaccinated young people are benefiting from a form of immunity.

This protein plays an important role in maintaining the integrity of the barrier that controls exchanges between the blood and the brain When faced with chronic stress, some people develop anxiety and depressive symptoms, while others show great resilience. How can such differences be explained? It could be attributable, at least in part, to a protein that acts as a cannabinoid receptor and is present in the structure that controls exchanges between the bloodstream and the brain, suggests a study just published in Nature Neuroscience .
