Scientists at ORNL have confirmed that bacteria-killing viruses called bacteriophages deploy a sneaky tactic when targeting their hosts: They use a standard genetic code when invading bacteria, then switch to an alternate code at later stages of

Joanna Tannous has found the perfect organism to study to satisfy her deeply curious nature, her skills in biochemistry and genetics, and a drive to create solutions for a better world. The organism is a poorly understood life form that greatly influences its environment and is unique enough to deserve its own biological kingdom: fungi.

Hydrologist Jesús “Chucho” Gomez-Velez is in the right place at the right time with the right tools and colleagues to explain how the smallest processes within river corridors can have a tremendous impact on large-scale ecosystems.

David McCollum, a senior scientist at the ORNL and lead for the lab’s contributions to the Net Zero World Initiative, was one of more than 35,000 attendees in Egypt at the November 2022 Sharm El-Sheikh United Nations Framework Convention on Climate Change, or UNFCCC, Conference of the Parties, also known as COP27.

The interaction of elemental iron with the vast stores of carbon locked away in Arctic soils is key to how greenhouse gases are emitted during thawing and should be included in models used to predict Earth’s climate.

The U.S. Departments of Energy and Defense teamed up to create a series of weld filler materials that could dramatically improve high-strength steel repair in vehicles, bridges and pipelines.

More than 300,000 students, teachers, and families across the country have been engaged in learning about what bioenergy can do to reduce carbon emissions and provide good jobs through a collaborative approach to science outreach adopted by the Center for Bioenergy Innovation (CBI) at Oak Ridge National Laboratory.
