UdeM astronomers find a way to measure temperature changes in a star with greater-than-ever precision, a breakthrough that promises to be particularly useful for detecting and studying exoplanets. Étienne Artigau, the UdeM astrophysicist who led the development of an innovative technique that provides precise information on a star's temperature variations.

A new Canadian study highlights the neurochemical consequences of head impacts that don't lead to a concussion but can still damage the brain. In a football game, an athlete takes a bad hit to the head. He doesn't feel dazed or confused: he seems to have escaped a concussion. However, despite the lack of concussive symptoms, the impact has disrupted the chemical balance in his brain, and this imbalance has consequences.

UdeM literature professor Marcello Vitali-Rosati looks at how, for better or worse, computerized large language models are changing how we write - and what we think about it. Computerized large language models (LLMs) are making inroads into the realm of literature. Their ability to generate coherent texts and mimic all manner of writing styles has sparked lively debate among writers, literary theorists and researchers.

Participating in a series of cognitive training sessions has helped Quebec seniors cope with memory loss - even five years later, an UdeM study finds. Can training your brain to remember things help you ward off the symptoms of Alzheimer's disease? A new Canadian study suggests that yes, it can - even five years after you got the training.

The global outbreak of COVID-19 in 2020 and resulting job losses led to a surge in suicidal ideation among Canadians, especially young people, a new UdeM-led study finds. Nearly three times as many Canadians - close to 8 per cent - thought of killing themselves in the first year of the COVID-19 pandemic than did in previous years, a new study led by Université de Montréal researchers suggests.

A study by UdeM professor Claude Perreault's team at IRIC proposes three potential functions for so-called parasite DNA sequences in T cell development. "Parasite" DNA sequences have three potential functions in the development of T (for thymus) lymphocytes, researchers led by Université de Montréal medical professor Claude Perreault show in a recent study.

Mathieu Ferron's work sheds light on the cellular mechanisms of insulin resistance in type 2 diabetes, which affects more than 1.2 million Quebecers.

A new study has found that flexible work arrangements can sometimes boost employee retention, but they can also lead to higher turnover. Most people think of flexible work arrangements as an employee benefit. But giving people the opportunity to work from home and choose their start and end times seems to have both positive and negative effects on employee retention.

The innovative approach to long-term hypoxia employed by Étienne Gagnon's team has led to the identification of a potential new marker for ovarian cancers. In a new study, the team led by Étienne Gagnon , Professor in the Department of Microbiology, Infectious Diseases and Immunology at the Université de Montréal and Director of IRIC's Cancer Immunobiology Research Unit, has developed a cell culture protocol that accurately reproduces the characteristic conditions of primary tumors.

A study published in Nature Communications raises new hope for the development of treatments for vascular disease, cancer and diabetic retinopathy. The behaviour of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels.

When Switzerland asked its citizens whether they believed sexual and gender minorities should be allowed to marry and adopt children, it took a taxing toll, says UdeM researcher Robert-Paul Juster. How did Switzerland's 2021 referendum on marriage equality, adoption and reproductive rights affect the well-being of the country's LGBTIQ+ community? A new international study involving Université de Montréal suggests that LGBTIQ+ individuals and their cisgender heterosexual allies exhibited more stress hormones during the controversial campaign.

A team of astronomers from UdeM has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising "super-Earth" covered in ice or water. When the exoplanet LHS 1140 b was first discovered, astronomers speculated that it might be a mini-Neptune: an essentially gaseous planet, but very small in size compared to Neptune.

A new study confirms the need to consider the indirect effects of health measure to promote the health and wellness of youth. A new study led by Nadia Roumeliotis , clinician-researcher at CHU Sainte-Justine and professor in the Department of Pediatrics at Université de Montréal, shows that the public health measures imposed in Canada during the COVID-19 pandemic were directly related to the hospitalization rate for adolescents aged 12 to 17 for eating disorders.

The discovery of the role played by -arrestins in the formation of the spinal cord at the embryonic stage opens up the prospect of exploring mechanisms that could repair spinal cord damage.

A Canadian team led by René Doyon will help design and build the ANDES spectrograph, which will search for signs of life outside the solar system. In 2014, the European Southern Observatory (ESO) began construction of the world's largest telescope, the Extremely Large Telescope (ELT), in Chile's Atacama Desert, 3,000 metres above sea level.

In 2014, the European Southern Observatory (ESO) began construction of the world's largest telescope, the Extremely Large Telescope (ELT), at an altitude of over 3,000 m in Chile's Atacama Desert. Scheduled to enter service in 2028, this giant telescope promises to mark a new era in ground-based astronomy.

Using pornography compulsively. Using it to cope with negative emotions. Being disturbed by one's own choice of pornographic material. Feeling ashamed of using pornography. According to a new international study led by Beáta Bothe , a professor in the Department of Psychology at Université de Montréal, these factors can predict problematic pornography use (PPU).

Astronomy professor Jonathan Gagné will be part of the Landolt space mission, solving problems caused by errors in astronomical calibrations. A major scientific breakthrough will be taking place soon thanks to NASA's Landolt space mission. The mission, at a cost of $19.5 million, will make it possible to measure stellar luminosities more accurately.

For the first time, a team co-led by Alexey Pshezhetsky resolved the structure of the enzyme deficient in Sanfilippo disease, a rare pediatric neurodegenerative disorder. For the first time, a team co-led by CHU Sainte-Justine researcher and professor in the Faculty of Medicine at Université de Montréal, Alexey Pshezhetsky has succeeded in resolving the unique structure of the HGSNAT enzyme, a deficiency of which causes Sanfilippo syndrome, a rare pediatric disease affecting the central nervous system.

A model that combines self-determination theory and social identity theory can shed light on team motivation and functioning, according to a recent study What are the underlying dynamics of group motivation in a team or organization' How does it take shape' And how does it influence a team's functioning and effectiveness' A recent article in Applied Psychology: An International Review attempts to answer these questions.
