This green process could be used to valorize other food remains rich in cellulose or lignin The banana is an excellent source of energy, nutritionists will tell you unanimously. So is the peel, according to Marie-Josée Dumont, but in the fuel sense of the term. The professor from the Department of Chemical Engineering at Laval University and her colleagues at McGill University have just taken a new step towards a fuel based on banana peel by substantially improving the efficiency of an existing chemical process.

Study led by Professor Patrick Lussier shows significant decline in recidivism of sex crimes in Canada over 80 years Encouraging news: between 1940 and 2019, the recidivism rate of sex offenders in this country has dropped by nearly 70%, according to a study published in the journal Criminology and Public Policy .

The efficacy and safety of taking aspirin before the eleventh week of pregnancy have not been demonstrated for this gestational problem, which affects about 5% of women Preeclampsia is a problem of pregnancy hypertension that increases the risk of premature delivery and leads to the death of approximately 60,000 women and 500,000 children worldwide each year, mainly in developing countries.

Researchers identify genes and markers associated with resistance to a commonly used hormone treatment Researchers at Laval University have discovered markers and genes associated with resistance to a hormone treatment commonly given to people with prostate cancer. These advances, reported in an article published by NAR Cancer , could lead to better use of this treatment and the development of new, more effective cancer treatments.

Poor sleep quality is associated with breast inflammation, a condition that can activate cascades of reactions leading to cancer Poor sleep quality may promote inflammation of breast tissue and increase the risk of breast cancer, suggests an exploratory study published in the journal Cytokine . Indeed, the Laval University research team behind the study showed a correlation between sleep quality characteristics and certain inflammatory markers associated with breast cancer risk.

Developed by a team at Laval University, this collar, which weighs less than a dime, will allow the study of lemming activity patterns during the summer Although lemmings play a central role in the Arctic terrestrial food chain, their living habits are still largely unknown. One reason is that these small rodents spend most of the year in tunnels in the ground or snow, out of sight of researchers.

If the past is any indication, the face of the boreal forest will not change dramatically in the coming decades Boreal forest trees are sensitive to climate change, but their migration in response to temperature fluctuations is not at a gallop. That's according to a study published today in the journal PNAS (Proceedings of the National Academy of Sciences of the United States), where a research team calculated how fast jack pine and black spruce moved north after the last ice age.

Under certain conditions, salmon caught and released have proportionally fewer offspring than salmon that were not caught by anglers Under certain conditions, catching and releasing a salmon would result in a decrease in the number of offspring it produces. This is what researchers from Laval University and their collaborators have shown in a study published in the journal Fisheries Management and Ecology .

Significant weight loss following bariatric surgery would make the brain about 5 years younger It was known that bariatric surgery led to a spectacular improvement in cardiometabolic health indicators. Now, a study just published in the journal NeuroImage shows that it also brings substantial benefits to the brain.

The great tit uses its sense of smell to find its way home We agree that the great tit will never be called upon to sniff out suspicious luggage at airports, but this species has more flair than we thought. In fact, a study published in Frontiers in Ecology and Evolution by a team of researchers including Linda Nowack, a doctoral student in the Department of Biology and the Centre d'études nordiques at Université Laval, shows that this bird uses olfactory signals to guide its movements.

Differential mortality of females would cause them to be three times less numerous than males when the population reaches a low point The intriguing cyclical variations of lemmings continue to surprise. The few answers that shed some light on this elusive phenomenon raise new questions that further thicken the mystery.

Nearly half of the people who should be referred quickly to a trauma center would fall under the radar of the triage method used in Quebec The prehospital trauma triage protocol used in Quebec correctly detects only 57% of people who should be transported quickly to a trauma center. And it's mainly the elderly who fall under the radar of this tool, reports a research team from Laval University in a study published by the Journal of Surgical Research .

Uncultivated agricultural land can capture as much carbon as land that has been reforested The federal government has committed to planting 2 billion trees by 2030 in order to reduce the amount of atmospheric CO2 and slow global warming. With this in mind, the idea of using abandoned farmland to plant some of these trees seems like an obvious and interesting strategy, but work by a team of scientists has shown that it is not.However, work carried out by a Quebec research team shows that one should be wary of the obvious.

Study shows that the more producers sell directly to consumers, the more they enjoy their work and the more economically satisfied they are A major Leger survey has already revealed that dentists and hairdressers are among the happiest workers in Quebec. What about farmers? Sometimes they are really happy, for example in terms of recognition in society, sometimes it is very difficult in terms of remuneration.

The Near InfraRed Planet Searcher instrument, designed in part at Laval University, has successfully made its first observations The Near InfraRed Planet Searcher (NIRPS) instrument, designed in part at the University of Montreal and Laval University, has successfully made its first observations. Installed on the European Southern Observatory's (ESO) 3.6-meter telescope at the La Silla Observatory in Chile, NIRPS' mission is to search for new exoplanets around stars in the solar neighborhood.

In male mice, alcohol consumption in the weeks preceding conception affects the transcription of genes important for fetal development Preventing fetal alcohol spectrum disorder (FASD) has traditionally been seen as a maternal responsibility, but a growing body of research suggests that fathers have a responsibility as well.

Even if the evidence of the effectiveness of cannabis is still very scarce, Quebecers are self-prescribing products from this plant for health problems ranging from pain to shyness Anxiety, depression, insomnia, shyness, migraines, muscle spasms, pain, loss of appetite, loss of libido. These are some of the health problems for which Quebecers self-prescribe cannabis, even though no reliable scientific study has yet demonstrated its effectiveness for these uses.

Mussel aquaculture sites are associated with increased abundance of several marine species Unlike intensive agriculture, which transforms habitats into monocultures that are not conducive to wildlife, shellfish aquaculture could have a very positive impact on other marine animals. This is at least the case for mussel farming in the Magdalen Islands, reports a study that has just been published in Frontiers in Marine Science .
