Scientists find X-rays can cause reversible resistance changes

In a new study, researchers at Argonne looked at how a material’s electrical resistance changes when it is irradiated with high-energy X-rays.

The world’s first protein characterization research facility directly attached to a light source will open in the near future at the Advanced Photon Source. The Advanced Protein Characterization Facility will use state-of-the-art robotics for gene cloning, protein expression, protein purification and protein crystallization. Click to enlarge.
Advanced Photon Source to remain leader in protein structure research for years

No X-ray facility in the world has supported more protein structure research and characterized more proteins than the Advanced Photon Source. Soon this 2/3-mile in circumference X-ray instrument will get a boost in efficiency that likely will translate into a big boon for the discovery of new pharmaceuticals, the control of genetic disorders and other diseases and advance the biotech industry.

Deep underground, microbes have to breathe iron and sulfur to get energy. Argonne scientists announced they have found what appears to be a missing step in the iron-sulfur cycle in underground aquifers. It turns out that sulfur (white-yellow power, on top) may be far more essential than previously thought in helping microbes harvest energy from iron minerals (from top to bottom: yellow goethite, red hematite, orange lepidocrocite) and produce sulfur-iron minerals, like mackinawite (black). Understanding these cycles is important for carbon sequestration and for predicting the fate of ground pollution. Click to enlarge. Photo by Mark Lopez/Argonne National Laboratory.
Study in 'Science' finds missing piece of biogeochemical puzzle in aquifers

A study published today in Science magazine by researchers from Argonne may dramatically shift our understanding of the complex dance of microbes and minerals that takes place in aquifers deep underground. This dance affects groundwater quality, the fate of contaminants in the ground and the emerging science of carbon sequestration.

Argonne researcher John Hummel will head the newly announced Center for Integrated Resiliency Analyses, or CIRA, a research center intended to enhance resiliency for major disruptive events such as climate change and natural disasters.
Argonne announces new Center for Integrated Resiliency Analyses

Argonne announced that it is forming a new research center to enhance resiliency for major disruptive events, such as natural disasters and climate change, called the Center for Integrated Resiliency Analyses (CIRA).

Ice core driller Tanner Kuhl works with the blue ice drill on Taylor Glacier in Antarctica. Argonne scientists used a newly developed technique called krypton-81 dating to determine that this ice was 120,000 years old—and the method could be used to date ice up to a million years old.

Scientists successfully use krypton to accurately date ancient Antarctic ice

A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating—a new technique that may allow them to locate and date ice that is more than a million years old.

Scientists gain new insight into mysterious electronic phenomenon

Thanks to a new Argonne study, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors. The riddle involves a phenomenon called the “pseudogap,” a region of energy levels in which relatively few electrons are allowed to exist.
