Heavy rainfall can cause rivers and drainage systems to overflow or dams to break, leading to flood events that bring damage to property and road systems as well potential loss of human life. One such event in 2008 cost $10 billion in damages for the entire state of Iowa. After the flood, the Iowa Flood…

A team led by the Department of Energy’s Oak Ridge National Laboratory has used sophisticated neutron scattering techniques to detect an elusive quantum state known as the Higgs amplitude mode in a two-dimensional material. The Higgs amplitude mode is a condensed matter cousin of the Higgs boson, the storied quantum particle theorized in the 1960s…

Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way for quantum calculations far beyond the limits of the ones and zeros of a computer’s binary code. A research team led by the Department of Energy’s Oak Ridge National…

Under a collaborative partnership between the National Aeronautics and Space Administration and the Department of Energy, a new automated measurement system developed at DOE’s Oak Ridge National Laboratory will ensure quality production of plutonium-238 while reducing handling by workers. NASA has funded ORNL and other national laboratories to develop a process that will restore U.S.…

Barely wider than a strand of human DNA, magnetic nanoparticles — such as those made from iron and platinum atoms — are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capacity and density, but understanding how magnetism works at the level of individual atoms…

 Scientists at the Department of Energy’s Oak Ridge National Laboratory have found a simple, reliable process to capture carbon dioxide directly from ambient air, offering a new option for carbon capture and storage strategies to combat global warming. Initially, the ORNL team was studying methods to remove environmental contaminants such as sulfate, chromate or phosphate…

Neutron scattering studies of a rare earth metal oxide have identified fundamental pieces to the quantum spin liquid puzzle, revealing a better understanding of how and why the magnetic moments within these materials exhibit exotic behaviors such as failing to freeze into an ordered arrangement even near absolute zero temperatures. In a paper published in Nature…

Supercomputer simulations at the Department of Energy’s Oak Ridge National Laboratory have played a key role in discovering a new class of drug candidates that hold promise to combat antibiotic resistance. In a study led by the University of Oklahoma with ORNL, the University of Tennessee and Saint Louis University, lab experiments were combined with…

Despite steady progress in detection and treatment in recent decades, cancer remains the second leading cause of death in the United States, cutting short the lives of approximately 500,000 people each year. To better understand and combat this disease, medical researchers rely on cancer registry programs–a national network of organizations that systematically collect demographic and…

A microbial partnership thriving in an acidic hot spring in Yellowstone National Park has surrendered some of its lifestyle secrets to researchers at the Department of Energy’s Oak Ridge National Laboratory. Mircea Podar of ORNL’s Biosciences Division led a team that isolated the archaeonNanopusillus acidilobi, cultured these tiny microbes – just 100 to 300 billionths…

When physicists Georg Bednorz and K. Alex Muller discovered the first high-temperature superconductors in 1986, it didn’t take much imagination to envision the potential technological benefits of harnessing such materials. High-temperature superconductors are materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (-196 degrees Celsius). Though their operating temperature may…

A new study published in Nature Climate Change indicates soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands. An international team led by Northern Arizona University scientists analyzed the results of 25 experiments from multiple research groups including the Department of Energy’s Oak Ridge National…
