DRI scientists Joe McConnell and Nathan Chellman co-authored a new study that examines a 6,000-year-old forest preserved in a Rocky Mountain ice patch. The research, which was led by the USGS and Montana State University, used the fossil wood to develop tree-ring based temperature estimates of the mid-Holocene period. The study can provide insight into the future elevational movement of forests under climate change, the scientists say.
The summer 2024 data collection effort provides community members, legislators, and scientists with detailed maps of the region’s urban heat island. The campaign took place on August 10th, a clear and hot day for our region. The measurements and maps produced from the campaign reveal a great deal of variability across the nearly 200 square miles of our study area and between the early morning, mid-afternoon, and early evening time periods of the study.
Lead exposure is responsible for a range of human health impacts, with even relatively low levels impacting the cognitive development of children. DRI scientists have previously used atmospheric pollution records preserved in Arctic ice cores to identify periods of lead pollution throughout the Roman Empire, and now new research expands on this finding to identify how this pollution may have affected the European population.
DRI scientists Joe McConnell and Nathan Chellman are co-authors on a new study that sheds light on a historical mystery that has plagued historians and scientists alike for nearly two centuries. Using Arctic ice core records, the team identified the volcano responsible for an enormous eruption in 1831 that caused global cooling of around 1°C, leading to crop failures and famines around the world.
Researchers from DRI and UNR teamed up for this new study, published October in Environmental Science & Technology. Using sociodemographic data from the U.S. Census Bureau and public health and air pollution information from the EPA between 2011 and 2019, the study identified higher estimated cancer risk tied to air toxics in urban communities, those with lower incomes, and those with higher proportions of racial minorities.
Patrick Hurbain, Ph.D., is an environmental epidemiologist working with Judy Chow, John Watson, and Xiaoliang Wang in the Environmental Analysis Facility. In the following interview, Hurbain discusses how his childhood in Stead influenced his career trajectory, his new study published in Environmental Science & Technology, and his hopes for bringing the chili cook-off back to DRI.
Tyler Doane, Ph.D., started in May 2024 as Assistant Research Professor in the Division of Hydrologic Sciences. He works remotely from Cleveland, Ohio, where his wife teaches bioethics at Case Western Reserve University’s medical school. Doane is a geomorphologist who received his Ph.D. at Vanderbilt University before completing a postdoctoral position at Indiana University, Bloomington. In the this Behind the Science interview, Doane talks about his interest in applying math to describe scientific phenomena, his interest in embracing noise and chaos to understand Earth systems, and his favorite method for coming up with new research questions.
DRI scientists are recruiting fifteen Fallon residents with private wells to participate in a water quality study. All fifteen study participants will receive free water quality results, and a subset of the well owners will receive water filtration systems. The research will be used to identify the spatial extent and potential sources of contaminants such as pesticides, microplastics, and flame retardants and quantify the efficacy of treatment systems to reduce concentrations in drinking water.
DRI’s annual awards and recognition ceremonies were held at our Reno and Las Vegas campuses in early October to honor scientists and staff members for their achievements. Along with the below awardees, several faculty and staff were recognized for their long-term service to the institute. DRI prides itself on fostering a fulfilling workplace that builds internal community and inspires scientific discovery.
Monica Gehrig joined DRI in summer 2023. She works with the STEM Education Program to bring science education to Nevada schools and builds partnerships with organizations like the Atomic Museum and the Southern Nevada Water Authority. Born and raised in Louisiana, she is now based at DRI’s Las Vegas campus. In this interview, Gehrig shares her passion for science education and why she considers it central to understanding the world, her circuitous path to DRI, and her many hobbies outside of work.
