New Deep Learning Techniques Lead to Materials Imaging Breakthrough

Supercomputers help researchers study the causes and effects—usually in that order—of complex phenomena. However, scientists occasionally need to deduce the origins of scientific phenomena based on observable results. These so-called inverse problems are notoriously difficult to solve, especially when the amount of data that must be analyzed outgrows traditional machine-learning…

Supercomputing for Swift Protein Modeling

Uncovering the molecular structures of proteins can help scientists elucidate biological functions of proteins and search for drug candidates for diseases. To better understand proteins, scientists can use imaging techniques to probe their molecular structures. However, many imaging techniques fall short of capturing details at the atomic level. That’s why…

Closing In on Fusion

The same process that fuels stars could one day be used to generate massive amounts of power here on Earth. Nuclear fusion—in which atomic nuclei fuse to form heavier nuclei and release energy in the process—promises to be a long-term, sustainable, and safe form of energy. But scientists are still trying to fine-tune the process of…
