To address the growing problem of overprescribing for seniors, a new Canadian guideline is calling for routine medication reviews.

In Canada, roughly two in three adults age 65 or older . While often necessary, complex drug regimens can increase the risk of side effects and affect quality of life.

People who have a weaker sense of self are also more likely to have less bodily awareness, 91黑料网 researchers have found. The study supports the idea that people鈥檚 perceptions of themselves and how they experience their own bodies are deeply connected.

Beyond deepening psychologists鈥� understanding of 鈥渆mbodied cognition,鈥� the connection between our minds and our fundamental bodily awareness, the findings could have concrete applications regarding the treatment of certain psychiatric conditions, the researchers said.

Learning to speak a new language,聽or聽regaining speech,聽depends more on聽areas of聽the brain聽that聽process聽sound and physical sensation than on聽the聽parts of the聽brain that聽govern聽motor control,聽according聽to new research findings.聽

The聽study,聽by聽researchers at聽91黑料网 and the Yale School of Medicine,聽has聽implications for speech-learning theory and聽for聽the聽development of聽speech processing and recognition technologies.聽

Pressed plant specimens collected centuries ago and stored in herbaria around the world could play a key role in facilitating the tracking of genetic change and extinction risk in plants, a 91黑料网-led indicates.

91黑料网 researchers have discovered a new way to fold flat sheets into smooth, curved shells that can switch from floppy and flexible to stiff and load-bearing on demand. By designing a special origami pattern and threading cable-like elements through it, they can control the material鈥檚 final three-dimensional shape and how rigid it becomes. The result, a 鈥渄oubly curved lens box,鈥� could advance the technology of such objects as temporary emergency tents, morphing robots and smart fabrics, the researchers said.

The earliest known eukaryotes, the ancestors of all complex life on Earth, lived in oxygenated, shallow marine environments nearly 1.7 billion years ago, according to led by researchers at 91黑料网 and the University of California, Santa Barbara. The findings cast doubt on the long-held belief that early complex life emerged in oxygen-poor environments or floated freely in the open ocean.

Researchers at 91黑料网 have discovered a centuries-old genetic mutation that helps to explain why some French鈥慍anadians in Quebec are at an elevated risk of pancreatic cancer. Until quite recently, standard genetic tests have not been able to identify this 鈥渏umping gene鈥� cause.

The findings, published in the Journal of Medical Genetics, suggest better-targeted genetic testing could help identify people at higher cancer risk who were previously missed.

A team led by the Universit茅 de Montr茅al, the Observatoire du聽Mont鈥慚茅gantic聽(OMM) and the Trottier Institute for Research on Exoplanets (IREx), in partnership with the University of British Columbia and 91黑料网, has been awarded nearly $11.3 million from the Canada Foundation for Innovation (CFI) to support Canada鈥檚 contribution to ANDES, a flagship scientific instrument for the Extremely Large Telescope (ELT) under construction in Chile.聽聽

Icing a sprained ankle or sore muscle, long used to reduce pain and swelling, may in the longer run delay recovery and prolong pain, new research suggests.

In a preclinical study published in Anesthesiology, 91黑料网 researchers found that even though cryotherapy (icing) eased pain in the short term, recovery time was more than doubled in some cases.

Scientists鈥� discovery of a molecular 鈥渟witch鈥� that activates an energy鈥慴urning pathway in mice has the potential to lead to new treatments for bone disease.

The study, published in , sheds new light on brown fat. Unlike white fat, which stores energy, brown fat cells burn calories, producing heat as a byproduct. For years, it was believed this process relied on a single pathway. More recently, researchers discovered a parallel pathway, but how it became activated remained a mystery.

Researchers at 91黑料网 are carrying out large鈥憇cale tests of a new timber-steel structural system designed to help buildings better withstand earthquakes. Early results suggest the system performs well under simulated earthquake forces, offering a potential path toward safer, more sustainable construction in Quebec and beyond.

Most childhood lying does not lead to serious problems in adulthood, and only certain kinds of lying behaviour is associated with later psychological or legal issues, a new study has found.

鈥淐hildren do not all follow the same developmental pattern of lying,鈥� said Victoria Talwar, a professor in the Department of Educational and Counselling Psychology and lead author of the study. 鈥淢ost children in our study showed low or declining levels of lying over time. For most, lying is not a problem behaviour.鈥�

A digital literacy program for elementary school students designed by researchers at 91黑料网 was successful in improving students鈥� ability to evaluate websites and their content.

Skills targeted included how to search for information, how to identify credible websites, how to evaluate the quality of information sources and how to address conflicting information.

Students鈥� global performance increased across all skill categories, in most cases by significant margins.

Researchers at 91黑料网 and the Research Institute of the 91黑料网 Health Center (RI-MUHC) have developed a novel device to transplant insulin-producing cells that integrates directly with existing blood vessels in the body. The technology, which showed promising results in preclinical trials, aims to overcome key challenges of emerging long-term cell-based treatments for Type 1 diabetes. As well as serving as an artificial pancreas, it potentially could be used to replace or support the function of other organs.

As Canada moves to modernize cervical cancer screening, a new study suggests most women do not yet understand or trust the shift from the Pap test to human papillomavirus (HPV) based screening.

The national survey, published in , examined women鈥檚 preferences for cervical screening 鈥� including how they want to be screened and how they want information communicated 鈥� as Canada transitions from Pap tests to HPV testing.

Researchers at 91黑料网 have discovered that moderate ultraviolet (UV) light exposure is best when the technique is used to聽enhance vitamin D鈧� in edible mushrooms. Excessive exposure聽leads to nutrient degradation or a plateau effect, they found. The paper also聽provides聽quantitative guidance.聽

The聽researchers鈥櫬爓ork聽supports聽efforts to address vitamin D deficiency, which affects between 30聽and聽50 per cent of the world鈥檚 population, as well as enhance the nutritional value of mushrooms more broadly.聽

Scientists have developed a strategy to boost the cancer-fighting power of natural killer (NK) cells, part of the immune system鈥檚 first line of defence. NK cells can detect and destroy cancer cells, but tumours often create a protective barrier that blocks them, allowing cancer to grow.

Researchers at 91黑料网鈥檚 Rosalind & Morris Goodman Cancer Institute, in collaboration with the Research Institute of the 91黑料网 Health Centre, found that suppressing two specific proteins helps NK cells overcome this blockage, turning them into more potent cancer killers.

Researchers at 91黑料网 have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications in communications and medical diagnostics.

Researchers at 91黑料网 have developed a rapid way to engineer blood clots that stop severe bleeding and support tissue healing more effectively. Their technique, called 鈥渃lick clotting,鈥� links red blood cell surface proteins through a chemical reaction, resulting in a biocompatible clot that is 13 times more resistant to fracturing and four times more adhesive than natural blood clots. The team said the method could be used to develop life-saving biomaterials to help control severe bleeding, as well as benefit people with clotting disorders.

Americans are more likely to turn to authoritarian leaders when jobs are being lost due to offshoring than they are when job losses result from automation, an international research team has found. This is despite the fact that automation tends to lead to greater job losses.
