In the study, published in the Journal of Experimental Medicine, the researchers showed […]

Researchers at Michigan Medicine have discovered yet another functional autoantibody in COVID-19 patients that contributes to the disease’s development and the “firestorm” of blood clots and inflammation it induces. A growing body of studies suggests COVID-19 emulates many aspects of systemic autoimmune disorders, including the release of a flurry of […]

Children and young people whose mothers had a BMI greater than 30 during early pregnancy are at an increased risk of fatty liver disease. This is shown in a register-based study from Karolinska Institutet and Harvard University published in the journal Journal of Hepatology. As obesity rates increase also in […]

A Tufts scientist is testing senolytics to counter senescent cells that promote afflictions like arthritis and Parkinson's disease. It’s not the fountain of youth, but a fast-emerging class of drugs could bring us closer to achieving the age-old quest for longer life, better health, and greater vitality. The drugs, called […]

Diagnostic nanoparticles could be used to monitor tumor recurrence after treatment or to perform routine cancer screenings. Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can […]

In the first year of the Covid-19 pandemic, deprived areas suffered more excess deaths than affluent areas, with a disproportionate impact on their younger age groups according to the early draft of a new study. In addition to the deaths from COVID-19, longstanding socioeconomic and geographical health inequalities for a […]

Bacteria’s role in gut health has received a lot of attention in recent years.
