Ottawa, ON, April 14, 2025 – Individuals with an emergency department (ED) visit or hospitalization due to cannabis were at 23% and 72% greater risk of a new dementia diagnosis within five years compared to individuals with an ED visit or hospitalization for any other reason or the general population, according to a new study published in JAMA Neurology.  “Long-term and heavy cannabis use has been associated with memory problems in midlife along with changes in brain structure associated with dementia,” says Dr. Daniel Myran, a Canada Research Chair in Social ...

The immune system must be able to quickly attack invaders like viruses, while also ignoring harmless stimuli, or allergies can result. Immune cells are known to ignore or “tolerate” molecules found on the body’s own healthy cells, for instance, as well as nonthreatening substances from outside the body like food. How the system achieves the latter has been unclear.  Now, a new study led by researchers at NYU Langone Health has revealed that a special group of cells in the intestines tamp down the immune responses caused by exposure to food proteins. ...

New York, NY [April 14, 2025]—A new multicenter study by researchers at the Icahn School of Medicine at Mount Sinai, in collaboration with the National Cancer Institute-funded Clinical Proteomic Tumor Analysis Consortium (CPTAC) and colleagues around the world, has discovered that the genes we are born with—known as germline genetic variants—play a powerful, underappreciated role in how cancer develops and behaves. Published in the April 14 online issue of Cell [https://doi.org/10.1016/j.cell.2025.03.026], the study is the first to detail how millions of inherited genetic differences influence the activity of thousands of proteins within tumors. Drawing on data ...

The number of California teens who have been treated for self-harm has ballooned in recent years, with an especially concerning increase among multiracial girls, according to new research from the University of California, Berkeley, published today (Monday, April 14) in JAMA Pediatrics. Using data from California emergency departments and inpatient care facilities from 2005 to 2021 — 231,232 reports in total — researchers examined both how the rate of annual nonfatal self-harm incidents has changed, as well as rate differences based on age, sex, and race and ethnicity. The study ...

Most cancer genome studies have focused on mutations in the tumor itself and how such gene variants allow a tumor to grow unchecked. A new study, led by researchers at Washington University School of Medicine in St. Louis, takes a deep dive into inherited cancer mutations measured in a healthy blood sample and reports how those mutations might take a toll on the body’s cells starting at birth, perhaps predisposing a person to develop cancers at various stages of life. The authors analyzed the inherited genomes of more than 1,000 cancer patients and determined how inherited mutations — ...

Popular CT Scans Could Account for 5% of All Cancer Cases A Year  Radiation from imaging could lead to lung, breast and other future cancers, with 10-fold increased risk for babies   CT scans may account for 5% of all cancers annually, according to a new study out of UC San Francisco that cautions against overusing and overdosing CTs.   The danger is greatest for infants, followed by children and adolescents. But adults also are at risk, since they are the most likely to get scans.   Nearly 103,000 cancers are predicted to result from the 93 million CTs that were ...

Deep-sea mining (DSM) not only poses significant environmental, social, and economic risks that may have far-reaching implications for coastal communities and Small Island Developing States (SIDS), it is also likely to negatively affect the business community, including insurers and investors, says a new study by researchers from the University of British Columbia and the Dona Bertarelli Philanthropy. DSM operations are expected to increase the negative impact on environmental indicators by up to 13 per cent, a change categorized as having “great” significance, relative to the “without” DSM scenario, ...

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide, with over 70% of patients diagnosed at an advanced stage due to the absence of symptoms. A key characteristic of advanced HCC is extrahepatic metastasis, particularly pulmonary metastasis, which is associated with a poor prognosis. Although multitargeted tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors have limited efficacy when used alone in advanced HCC, their combination can enhance outcomes for patients with pulmonary metastases. Meanwhile, pulmonary metastasectomy ...

Complications during pregnancy (or adverse pregnancy outcomes), like gestational diabetes and newly developed high blood pressure, act as nature’s stress test and may uncover an individual’s risk for heart disease later in life, according to new research published in the JACC, the flagship journal of the American College of Cardiology. The study also highlights how weight management before pregnancy may not only improve maternal health but also reduce future cardiovascular disease risk. The observational study, which ...

Cardiovascular disease is by far the most common cause of death worldwide, and myocardial infarction is the most common acute event. For those who survive a myocardial infarction, the risk of a new heart attack is greatest in the first year after the initial event because the blood vessels are more sensitive, making it easier for blood clots to develop. Reducing the “bad” cholesterol in the blood stabilises changes in the vessels, decreasing the risk for new events. The current established routine treatment is to treat with high-potency statins, immediately after the infarction. However, the majority ...

New tool for cutting DNA: promising prospects for biotechnology  An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA   A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut.  This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.   Recently, ...

Victoria, BC— For the first time, footprints of armoured dinosaurs with tail clubs have been identified, following discoveries made in the Canadian Rockies. The 100-million-year-old fossilized footprints were found at sites at both Tumbler Ridge, BC, and northwestern Alberta. There are two main groups of ankylosaurs. Nodosaurid ankylosaurs have a flexible tail and four toes, while ankylosaurid ankylosaurs have a sledgehammer-like tail club, and only three toes on their feet. Unlike the well-known ankylosaur footprints called Tetrapodosaurus ...

COLUMBUS, Ohio – Insomnia and hazardous drinking are so closely intertwined that estimates suggest at least one-third, and as many as 91%, of people who have a hard time with sleep also misuse alcohol. A new study suggests that perceived stress and depression factor into the relationship between the two conditions – perhaps not a surprise. But because the relationship between insomnia and heavy drinking goes in both directions, the influence of stress or depression depends on which condition came first, the analysis found. “We were most interested in how insomnia leads to drinking, and we found that seems to occur primarily through ...

Years of research in the field of genetics have offered interesting insights spanning the origins and development of heredity and traits, offering valuable information on its influence on every aspect of life, right from eye color to susceptibility to certain diseases.
