A snapshot of silicene (shown in yellow), a 2-D material made up of silicon atoms, as it grows on iridium substrate (shown in red). The image was taken from a molecular dynamics simulation, which Argonne researchers used to predict the growth and evolution of silicene.

The flat and the curious

Argonne researchers have simulated the growth of the 2-D material silicene. Their work, published in Nanoscale, delivers new and useful insights on the material’s properties and behavior and offers a predictive model for other researchers studying 2-D materials.

A 3-D rendering shows simulated solar convection realized at different rotation rates. Regions of upflow and downflow are rendered in red and blue, respectively. As rotational influence increases from left (non-rotating) to right (rapidly rotating), convective patterns become increasingly more organized and elongated. Understanding the sun's location along this spectrum represents a major step toward understanding how it sustains a magnetic field.

The inner secrets of planets and stars

An INCITE research team, led by Jonathan Aurnou of UCLA, is using Mira to develop advanced models to study magnetic field generation on Earth, Jupiter and the sun at an unprecedented level of detail.

Field of meteorologists’ dreams

With more than 200 instruments, the Southern Great Plains (SGP) atmospheric observatory is the world’s largest and most extensive climate research facility. This year, the site celebrates 25 years of operations, helping scientists gain vital insights into the Earth’s cloud, aerosol and atmospheric processes.

Argonne scientists have determined the molecular structure of this protein complex — an insight that could lead to new biomedical strategies for overcoming pathogenic bacteria that cause infectious diseases. This representation shows the neutralized complex of the CdiA toxin (purple and beige) with the CdiI immunity protein (orange and pink) and the elongation factor EF-Tu (grey and green).

Hacking the bacterial social network

U.S. Department of Energy (DOE) scientists have determined the molecular structures of a highly specialized set of proteins that are used by a strain of E. coli bacteria to communicate and defend their turf.

The Argonne-led <em>Multiscale Coupled Urban Systems</em> project aims to help city planners better examine complex systems, understand the relationships between them and predict how changes will affect them. The ultimate goal is to help officials identify the best solutions to benefit urban communities. (Image by Argonne National Laboratory.)
Exascale and the city

The Argonne-led Multiscale Coupled Urban Systems project will create a computational framework for urban developers and planners to evaluate integrated models of city systems and processes. With this framework, city planners can better examine complex systems, understand the relationships between them and predict how changes will affect them. It can ultimately help officials identify the best solutions to benefit urban communities.

Several of the college students who spent the summer researching at Argonne were from the University of Chicago. They focused on projects related to nuclear energy, ranging from the nuts and bolts of a reactor to education and non-proliferation. (Image by Argonne National Laboratory.)
Demystifying nuclear energy

As part of Argonne’s summer internship program, four college students focused on nuclear energy projects for the laboratory, ranging from the nuts and bolts of a reactor to education and non-proliferation.

Recently, 70 scientists — graduate students, computational scientists, and postdoctoral and early-career researchers — attended the fifth annual Argonne Training Program on Extreme-Scale Computing (ATPESC) in St. Charles, Illinois. Over two weeks, they learned how to seize opportunities offered by the world’s fastest supercomputers. (Image by Argonne National Laboratory.)
Leaning into the supercomputing learning curve

Scientists need to learn how to take advantage of exascale computing. This is the mission of the Argonne Training Program on Extreme-Scale Computing (ATPESC), which held its annual two-week training workshops over the summer.

In high school, Tavis Reed earned an ACT-SO gold medal for devising a technique, now patent pending, that efficiently produces ethanol. Reed has explored a wide range of research fields, from microbes to batteries, via Argonne’s Student Research Participation Program. (Image by Argonne National Laboratory.)
Stairway to science

The ACT-SO program launches high school student on path to Argonne’s student research program, a provisional patent and the pursuit of degree at Washington University in St. Louis.

Argonne and the University of Chicago partnered to help these Chicago high school students study different kinds of alternative energy. (Image by Argonne National Laboratory.)
After-school energy rush

The U.S. Department of Energy’s (DOE) Argonne National Laboratory partnered with the University of Chicago to sponsor “All About Energy,” a six-week program that gives Chicago public high school students an up-close look at careers in science, technology, engineering and mathematics (STEM) and a chance to learn what it means to be a scientist.

This shows the HACC cosmology simulation, which combines high spatial and temporal resolution in a large cosmological volume. The high temporal resolution tracks the evolution of structures in great detail and correlates formation histories to the environments in which the structures form.

Cartography of the cosmos

There are hundreds of billions of stars in our own Milky Way galaxy, interspersed with all manner of matter, from the dark to the sublime. This is the universe that Argonne researcher Salman Habib is trying to reconstruct, structure by structure, combining telescope surveys with next-generation data analysis and simulation techniques currently being primed for exascale computing.
