Noise-induced hearing loss affects about 40 million adults in the United States ages 20-69. This type of hearing loss is caused by exposure to loud sounds, either from a sudden loud noise like a firework or from repeated exposure to loud sounds over time, like a lawn mower. It can be prevented by wearing hearing protection, but for people in certain industries, earplugs can make work more challenging. That’s why an interdisciplinary team of researchers at the University of Minnesota Duluth (UMD) are working to find the best earplugs for musicians and referees.Learn more about research at UMD: https://research.d.umn.edu/

- 0:52What happens when you drop a steel wedge filled with dry ice into a lake?Researchers at the University of Minnesota Duluth (UMD) and the U.S. Geological Survey (USGS) are studying lake sediment to reconstruct long-term climate and flood histories in the region. Using a technique called freeze coring, they extract intact layers of mud, called varves, from the bottom of lakes. These varves form annually and preserve chemical and physical clues about rainfall and weather conditions dating back hundreds to thousands of years. This method enables scientists to analyze extreme precipitation trends far beyond modern data limits. The findings could improve flood modeling and guide infrastructure decisions.Read more about this impactful research: https://news.d.umn.edu/articles/flood-history
