Actinium-225 is a radioactive isotope that emits four powerful alpha particles as it decays through a short-lived chain of elements before reaching stable bismuth. Because alpha radiation is highly energetic but travels only a tiny distance, scientists can harness it in targeted alpha therapy to precisely destroy cancer cells while minimizing damage to healthy tissue.
New research from ORNL, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about controlling heat flow in solid materials.
Researchers at ORNL provided the first comprehensive analysis of the specific costs of power outages to local customers across the nation. The study, incorporated in ORNL’s TASTI-GRID application, helps governments and utilities make decisions about grid modernization to reduce serious risks to public health and safety.
ORNL is vital to a robust domestic isotope R&D and production ecosystem in the U.S. and is able to provide more than 300 isotopes that are used by researchers, pharmaceutical companies, and others. For almost 80 years, ORNL has produced medical isotopes to help diagnose and treat a variety of diseases and conditions, from heart disease to cancer.
Researchers at ORNL used computer models to study whether abandoned coal mines could be turned into underground systems that store energy by pumping water.
Six nature walks at the Oak Ridge Reservation have been scheduled for the 2026 season. The ORNL-organized walks, which are open to the public, will take place at locations across the reservation.
ORNL named Budhendra “Budhu” Bhaduri its first Chief Data Officer, effective February 1. The newly established role unifies ORNL’s enterprise data strategy to accelerate mission impact across open science, energy innovation, national security and laboratory operations.
ORNL is announcing the creation of the Institute for Next-Generation Data Centers, a new national institute dedicated to advancing the design, operation and integration of artificial intelligence data centers into the United States’ energy system.
Nina Gottschling is a Wigner Fellow at ORNL whose research focuses on uncertainty quantification, inverse problems, and photonic quantum computing, with an emphasis on mathematical accuracy bounds for AI and scientific computing. She bridges rigorous mathematics, simulation and experiment to advance computational and quantum technologies.
Carrie Eckert is working toward a future in which engineered microbes and plants are the workhorses of ultra-efficient biofactories, turning biomass into high-value products. As co-chief science officer for DOE's Center for Bioenergy Innovation at ORNL, she is stewarding a team of scientists across the country who are making that vision a reality.
