Breathing thin air at extreme altitudes presents a significant challenge — there’s simply less oxygen with every lungful. Yet, for more than 10,000 years, Tibetan women living on the high Tibetan Plateau have not only survived but thrived in that environment. A new study led by Cynthia Beall,… Continue Reading

Immunotherapies that mobilize a patient’s own immune system to fight cancer have become a treatment pillar. These therapies, including CAR T-cell therapy, have performed well in cancers like leukemias and lymphomas, but the results have been less promising in solid tumors. A team led by… Continue Reading

A group of McMaster researchers who routinely work with bacteriophages — viruses that eat bacteria — had a pleasant and potentially very important surprise while preparing slides to view under a powerful microscope. After treating samples of what are informally called phages so they could be… Continue Reading

People with opioid use disorder in British Columbia who received methadone had a 37-40 per cent lower rate of treatment discontinuation compared with those who received buprenorphine/naloxone. The new research, published this week in the Journal of the American Medical Association, evaluated the… Continue Reading

Healthy lifestyle behaviors, such as good nutrition, smoking cessation and being physically active, along with routine health screenings and managing risk factors for cardiovascular disease and stroke with medication, can help prevent individuals from having a first stroke.

Scientists from the University of Leicester have discovered that tuberculosis disrupts glucose metabolism in the body. The findings, which have now been published in PLoS Pathogens complement the understanding that diabetes worsens the symptoms of tuberculosis. Importantly, they now say,… Continue Reading

New research from King’s College London has revealed a connection between ancient viral DNA embedded in the human genome and the genetic risk for two major diseases that affect the central nervous system. The study, conducted by researchers from King’s College London and Northwell Health,… Continue Reading

All animals possess some capacity for repairing and replacing the lining of their intestines, a process called intestinal regeneration. In mammals, including humans, this constant but relatively minor turnover of cells helps the intestine keep up with the daily requirements of eating. It is… Continue Reading

Myasthenia gravis (MG) is a chronic autoimmune disorder in which antibodies block communication between nerves and muscle, resulting in weakness of the skeletal muscles. It can cause double vision, difficulty swallowing, and, occasionally, serious breathing difficulties, among other symptoms…. Continue Reading

A 3D atlas of developing mice brains using advanced imaging and microscopy techniques has been created by a team of researchers at Penn State College of Medicine and collaborators from five different institutes. This new atlas provides a more dynamic, 360-degree picture of the whole mammalian… Continue Reading
