"Monkey wrench" molecule jams tuberculosis protein

Scientists at Argonne National Laboratory were part of a recent discovery of a new molecule that attacks tuberculosis-causing bacteria by cutting off its production of a chemical necessary for its survival.

New prototypes for superconducting undulators show promise for more powerful, versatile X-ray beams

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Argonne National Laboratory have collaborated to design, build and test two devices that utilize different superconducting materials and could make X-ray lasers more powerful, versatile, compact and durable.

Inside an engine is a harsh place: the intense heat and pressure cause the parts to wear away and break down. But this new coating, which rebuilds itself as soon as it begins to break down, could protect engine parts (and more) for much longer.
9 cool science & tech stories from Argonne in 2016

As 2016 draws to a close, we’re looking back at just a few of the many cool stories that came out of research conducted by Argonne scientists and engineers this year. These discoveries are just a tiny sample of how Argonne researchers help address energy challenges, boost the economy through new discoveries and technologies, and expand scientific knowledge.

Building project managers and scientific leads confer at the site of a new clean room under construction at Argonne National Laboratory. When completed, the lab will enable scientists and engineers to build extremely sensitive detectors — such as those capable of detecting light from the early days of the universe.

Building a room clean enough to make sensors to find light from the birth of the universe

Work is underway at Argonne on an expansion of its “clean room.” The new lab will be specially suited for building parts for ultra-sensitive detectors — such as those to carry out improved X-ray research, or for the South Pole Telescope to search for light from the early days of the universe.

High schoolers study ancient pottery at Advanced Photon Source

The experimental facilities of a typical high school physics classroom don’t usually include a synchrotron. But Natalie Ferguson and more than 60 of her schoolmates not only got to see the Advanced Photon Source: they used it to do research.

Researchers from the University of Guelph have visited the Advanced Photon Source at Argonne National Laboratory for the past three years to use the facility’s bright X-rays to study the structure of edible fats, present in foods like oils, milk fat, cheese and much more. In this photo, Braulio Macias Rodriguez, a University of Guelph graduate student, left, and Fernanda Peyronel, research associate, examine a sample of anhydrous milk fat at beamline 9ID-D, the ultra-small-angle scattering facility.
Tasty fat: X-rays finding the blueprint of why fat is yummy

Over three years, a University of Guelph team has brought increasingly complex samples of edible fat to the Advanced Photon Source for research. They are using data from the facility to characterize the nanoscale structure of different kinds of edible fats and applying the data to a model that predicts the effect of processes like heating and mixing on fat structure.
