DRI Internships Offer TMCC Students Insight Into Science Careers 

This summer, DRI brought eighteen students from Truckee Meadows Community College (TMCC) to our Reno campus for a paid, immersive research experience. Over the course of the ten week program, students worked under the mentorship of DRI faculty members to learn about the process of using scientific research to solve real-world problems. This unique internship program welcomes all students, not only those pursuing majors in science.

DRI Launches Collaborative New Project Investigating PFAS and Microplastics for Department of Defense 

DRI’s Monica Arienzo, Director of the Microplastics and Environmental Chemistry Laboratory, was recently awarded $250,000 by the Department of Defense to investigate laundering and textile degradation as a possible source of PFAS and microplastic pollution. The one-year grant will fund laboratory studies and analysis led by Arienzo, with DRI’s Daniel Saftner and Yeongkwon Son contributing to the work. Matt Reeves of Western Michigan University is partnering with the DRI scientists for the project.

Hidden Life Beneath Antarctic Ice: Microbial Diversity and Survival Strategies Revealed in Mercer Subglacial Lake 

Hundreds of lakes exist beneath the Antarctic ice sheet, and very few have ever been explored by scientists. Now, an international research team has published their findings from an ambitious effort to drill over 1,000 meters into the ice to sample the life hidden in one known as Mercer Subglacial Lake. The project, referred to as the Subglacial Antarctic Lake Scientific Access (SALSA) project, was documented in detail for the film The Lake at the Bottom of the World.

Meet Erik Henzl

Erik Henzl is a Staff Research Scientist and environmental economist who joined DRI in January 2025. Based at DRI’s Reno campus, he is currently focused on estimating the water and energy required to support Nevada’s rapidly expanding data centers now and into the future. In the following interview, he shares his passion for learning as a vocation and how his research will help Nevada navigate its growing role in the digital world.

DRI Contributes to Study Using AI in Wastewater Surveillance for Detection of Emerging Virus Pathogens 

DRI Microbiologist Duane Moser co-authored a new study which introduces an AI-driven approach for the rapid detection and characterization of emerging variants during wastewater surveillance. The research builds on his earlier work helping to establish wastewater monitoring as a cost-effective tool for tracking pathogens during the COVID-19 pandemic.

Scientists Find the First Ice Core From the European Alps That Dates Back to the Last Ice Age

The new study, published in the June issue of PNAS Nexus, examines a 40-meter long ice core from Mont Blanc’s Dôme du Goûter. Using radiocarbon dating techniques, the research team found that the glacier provides an intact record of aerosols and climate dating back at least 12,000 years. Aerosols are small droplets and particles in the air such as desert dust, sea salts, sulfur from volcanic eruptions, soot from forest fires, as well as pollutants and other emissions from human activities.

A New, Detailed Analysis of the Benefits and Trade-offs of Urban Street Trees in Las Vegas

Earth is hotter than it has been in 125,000 years, scientists say, and Las Vegas continues to break temperature records. Planting and preserving the city’s street trees is one method that brings many benefits, from the cool air of their shade to their ability to store carbon. Now, a new study takes a deeper look at just how much trees can offer Sin City, as well as the water tradeoffs inherent in growing trees in a desert.

Desert Lichen Offers New Evidence for the Possibility of Life on Other Planets

The question of whether Earth is alone in harboring life has captivated humanity for millennia. In recent years, scientists have turned to Earth-like planets in other solar systems that may show the most promise, but many revolve around stars that emit much stronger solar radiation than our own. Now, a new study offers evidence that life as we know it may be able to thrive on those Earth-like exoplanets.
