The American Heart Association recognizes 9 Kids Heart Challenge and American Heart Challenge schools, educators and students for building healthier communities

Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviours in mice, even when natural rewards such as food or social contact are available. The study has been published in the journal Science Advances and may contribute to increased knowledge about obsessive-compulsive disorder and addiction.

Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune “attack” cells in the pancreatic lymph nodes that appear earlier in the disease could offer the first real chance to detect – and even stop- T1D, according to new research from the Perelman School of Medicine at the University of Pennsylvania detailed in Science Immunology.

New research, led by LJI scientists, offers a potential way to boost tissue-resident memory T cell numbers to better fight disease.

An Emory University study, published Friday by Science Advances, provides the first evidence that exposure to higher temperatures during pregnancy is linked to specific molecular changes in mothers that are also associated with preterm birth.
