A new paper from a team of Cornell University researchers shows that the highly pathogenic avian influenza H5N1 virus causes severe mastitis and decreased milk production in dairy cows, a drop-off that may extend beyond the clinical outbreak period.

The Global Virus Network (GVN), a coalition of leading human and animal virologists from 80+ Centers of Excellence and Affiliates in more than 40 countries, is sounding the alarm over a sharp resurgence of measles cases in the United States and globally. This resurgence, fueled by falling vaccination rates, threatens to erode decades of public health progress.

Developed by researchers at Oregon Health & Science University’s Knight Cancer Institute, the tool, dubbed OmicsTweezer, uses advanced machine learning techniques to analyze biological data at a scale large enough to estimate the composition of cell types in a sample of tissue that may be taken from a biopsy. This process allows scientists to map the cellular makeup of tumors and surrounding tissues — an area known as the tumor microenvironment.

The American Heart Association announces the appointment of two leading health and science leaders, Jennifer Ashton, M.D., M.S. and Joseph Woo, M.D., FAHA, to its volunteer Board of Directors, effective July 1, 2025.
