Of all the types of breast cancer, triple negative breast cancer (TNBC) is the most aggressive and lacks specific therapies. TNBC is also more likely to metastasize, or travel through the bloodstream to spread to other organs, which causes most…

Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor, however, is whether the active substances actually kill the pathogens in the body. Researchers at the University of…

Cardiovascular risk factors, including higher body mass index (BMI) and waist circumference, in childhood and adolescence are associated with poorer cognitive function in young adulthood, according to a study published online Jan. 15 in Pediatrics. Henri Salo, M.D., from the…

Many people are surprised to learn that clinical trials aren’t just for people who have run out of standard treatment options, but are an important part of cancer care at every stage and most aspects of diagnosis and treatment. They…

Canadian cultural resource management archaeologists—professional consultants involved in environmental assessment and compliance processes—are increasingly finding themselves in the public eye when their work intersects with the development or disaster response related infrastructure projects. Public or media discussions often arise when…

Many low-income Californians prescribed wildly popular weight loss drugs lost their coverage for the medications at the start of the new year. Health officials are recommending diet and exercise as alternatives to heavily advertised weight-loss drugs like Wegovy and Zepbound,…

New research in The American Journal of Pathology has identified neuroinflammation, driven by microglia (immune cells), as a primary underlying driver of prolonged negative feelings (hyperkatifeia) caused by repeated, sustained cycles of binge drinking. EtOH: ethanol; BDNF: Brain-Derived Neurotrophic Factor…

A new study from Karolinska Institutet, published in Nature Communications, reveals how rhythmic brain waves known as alpha oscillations help us distinguish between our own body and the external world. The findings offer new insights into how the brain integrates…

In a world facing rising economic uncertainty and instability, look to cross-border investment activity for solid clues about what’s next for economic growth and foreign exchange rates. That’s a key finding by Steven Riddiough, an associate professor of finance at…

Inside the body, a 24-hour rhythm, known as the circadian rhythm, quietly coordinates when we sleep, wake, eat and recover. This internal timing system helps keep organs and hormones working in sync. When it becomes disrupted, the effects may extend…

A study led by researchers from the University of Liverpool has found that spikes in blood sugar after meals may increase the risk of Alzheimer’s disease. The work is published in the journal Diabetes, Obesity and Metabolism. While research has…
