Scientists at La Jolla Institute for Immunology (LJI) have discovered that the influenza vaccine FluMist can stimulate immunity in the upper airways of adults. This is the first time researchers have tracked how immune cells in the upper airways respond to an intranasal vaccine (given via a spray in the nose). The new study gives scientists a guide for measuring the effectiveness of new intranasal vaccines against RSV, COVID-19, and other respiratory diseases.

For decades, research has linked coffee consumption to longer life and lower risk of chronic disease — but exactly how those benefits occur has remained unclear.

Now, new research from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) suggests that compounds in coffee may work, in part, by activating a receptor in the body known as NR4A1 — a protein increasingly recognized for its role in aging, stress response and disease.

Nerve fibers within melanomas can slow the growth of these tumors, according to a study led by Weill Cornell Medicine investigators. The findings help clarify the emerging field of cancer neuroscience and may inform future therapeutic strategies.
