In a National Geographic story about whether food dyes make ADHD worse, Joel Nigg, Ph.D., says more research is needed. “Artificial dyes have been studied in humans only as groups of dyes together, so we don’t actually know if any one dye is particularly problematic,” he says.

In a story about the COVID-19 virus circulating this winter, Dawn Nolt, M.D., tells HuffPost that common COVID symptoms this year are familiar, including cough and shortness of breath. She says, “I think the one thing we’re not seeing is ... that loss of smell or taste that people often talked about early in the pandemic.”

New research led by Luiz Bertassoni, Ph.D., uncovers how specialized cells surrounding small blood vessels contribute to blood vessel dysfunction in chronic diseases such as cancer, diabetes and fibrosis. He says, “Our findings represent a paradigm shift, showing how perivascular cells, instead, act as important sentinels. They detect changes in tissues and coordinating vascular responses. This opens the door to entirely new treatment strategies.”

In coverage of Portland Opportunities Industrialization Center's new grant funding to expand violence prevention efforts, OHSU is mentioned as a key partner in research and intervention programs, such as Healing Hurt People.

New research reveals the complex orchestration of neurons in the brain that turns raw noise — the compression of airwaves and pressure on the inner ear — into the ability to, for instance, understand speech, enjoy music and discern train whistles from car horns. Laurence Trussell, Ph.D., says, “Our ability to understand the meaning of sounds depends on the ability of the brain to represent whether the sound is high- or low-pitched, loud or soft, near or far. All of that requires very specialized neurocircuitry and highly specialized types of neurons in the brain."

In stories about the severity of this flu season, Dawn Nolt, M.D., notes that there has been a rapid rise in flu cases locally and nationally, and gives advice on how to stay healthy. Among other things, she says, “After you recover from flu, there are a lot of other respiratory germs out there, so really wash your hands meticulously.”
