Testing shows people generate more respiratory aerosols during endurance exercise than resistance exercise

A team of biology researchers from Universität der Bundeswehr, Technische Universität München and the University of Cassino and Southern Lazio, has found that people exhale more aerosols when engaging in endurance exercise than they do when engaging in resistance exercise. The study is published in the Proceedings of the National Academy of Sciences.

Nerve–immune cell interactions in the lungs may drive the development of allergic asthma

Allergic asthma—which is characterized by wheezing and breathing difficulties triggered by inhaled allergens such as pollen, mold, and pet dander—is the most common chronic disease among children, and it can persist into adulthood. New research led by investigators at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), reveals how the relationship between nerves and immune cells in the lungs can contribute to the development of this condition.

Study: Risk of cancer remains high for women over 50 with genetic BRCA1 or BRCA2 mutation

Although genetic mutations in BRCA1 or BRCA2 are associated with a younger onset of breast and ovarian cancer, women with these genetic mutations continue to face a high risk of cancer incidence after age 50, even if they have not been previously diagnosed with cancer. This is according to a new study led by Kelly Metcalfe, a professor at the Lawrence S. Bloomberg Faculty of Nursing.
