A multi-institutional study led by the University of California, Davis, finds that living in urban areas with a higher percentage of visible trees is associated with a 4% decrease in cardiovascular disease. By comparison, living in urban areas with a higher percentage of grass was associated with a 6% increase in cardiovascular disease. Likewise, a higher rate of other types of green space, like bushes or shrubs, was associated with a 3% increase in cardiovascular disease. The new research was published in Environmental Epidemiology.
Rye pollen slows tumor growth in animal models of cancer. Chemists determined the 3D structure of the bioactive molecules in rye pollen. With new blueprint, researchers could develop strategies for cancer treatment.
New Orleans, LA, (January 21, 2026) - A research team led by Dr. Rinku Majumder from LSU Health New Orleans has published a groundbreaking study in the prestigious Journal of Clinical Investigation showing how obesity and estrogen-based medications (including hormonal therapies and oral contraceptives) act together to dramatically increase the thrombotic risk in premenopausal women.
A new medical large language model (LLM) achieved over 91 percent accuracy in identifying female participants diagnosed with major depressive disorder after analyzing a short WhatsApp audio recording where participants described their week, according to a study published January 21, 2026 in the open-access journal PLOS Mental Health by Victor H. O. Otani, from Santa Casa de São Paulo School of Medical Sciences and Infinity Doctors Inc., Brazil, and colleagues.
Nitric oxide is a therapeutic gas that researchers at Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system, helped establish as a life-saving therapy for hundreds of thousands of newborns with congenital heart disease. Nearly 30 years later, investigators from the same laboratory at Mass General Brigham report that high-dose inhaled nitric oxide (iNO) demonstrates potential antimicrobial activity in preclinical models and is safe and feasible in early human studies, supporting further clinical investigation. The findings are published in Science Translational Medicine.
