First Look shows undergraduate students from underrepresented groups what it’s like to be part of Argonne’s world-class community, while preparing them to join as interns.

In an AI-based exploration of 160 billion organic molecules, Argonne National Laboratory scientists identified about 40 liquid hydrogen carriers that could one day fuel cars, trucks, buses, trains and ships and generate energy for consumers.

In the culmination of a decade’s worth of effort, the DES collaboration of scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.

Argonne researchers have invented a cathode material that replaces lithium with sodium ions and would be significantly cheaper. Sodium is far more naturally abundant and easily mined than lithium and is thus an attractive option for electric vehicles.

Argonne National Laboratory’s Theta supercomputer will be retired at the end of 2023, ending a productive run of enabling scientific breakthroughs in areas ranging from materials discovery to supernova simulations.
