Neutron experiments can take days to complete, requiring researchers to work long shifts to monitor progress and make necessary adjustments. But thanks to advances in artificial intelligence and machine learning, experiments can now be done remotely and in half the time.

After a highly lauded research campaign that successfully redesigned a hepatitis C drug into one of the leading drug treatments for COVID-19, scientists at ORNL are now turning their drug design approach toward cancer.

For more than half a century, the 1,000-foot-diameter spherical reflector dish at the Arecibo Observatory in Puerto Rico was the largest radio telescope in the world. Completed in 1963, the dish was built in a natural sinkhole, with the telescope’s feed antenna suspended 500 feet above the dish on a 1.8-million-pound steel platform. Three concrete towers and more than 4 miles of steel cables supported the platform.
![Upgrades to the particle accelerator enabling the record 1.7-megawatt beam power at the Spallation Neutron Source included adding 28 high-power radio-frequency klystrons (red tubes) to provide higher power for the accelerator.

The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory set a world record when its particle accelerator beam operating power reached 1.7 megawatts, substantially improving on the facility’s original design capability.

Creating energy the way the sun and stars do — through nuclear fusion — is one of the grand challenges facing science and technology. What’s easy for the sun and its billions of relatives turns out to be particularly difficult on Earth.

Ken Herwig's scientific drive crystallized in his youth when he solved a tough algebra word problem in his head while tossing newspapers from his bicycle. He said the joy he felt in that moment as a teenager fueled his determination to conquer mathematical mysteries. And he did.

When opportunity meets talent, great things happen. The laser comb developed at ORNL serves as such an example.
![ORNL seismic researcher Chengping Chai placed seismic sensors on the ground at various distances from an ORNL nuclear reactor to learn whether they could detect its operating state.

Like most scientists, Chengping Chai is not content with the surface of things: He wants to probe beyond to learn what’s really going on. But in his case, he is literally building a map of the world beneath, using seismic and acoustic data that reveal when and where the earth moves.
