Researchers Find Previously Unknown Links between Microbial Bile Acids and the Risk of Colon Cancer

Microbes living in our guts help us digest food by reshaping the bile acids that our livers produce for breaking down fats. It turns out that two of these microbially-modified bile acids may affect our risk—in opposite directions—for developing colon cancer.

The link between these bile acids and colon cancer risk was recently uncovered as University of Wisconsin–Madison scientists sought to better understand the relationship between gut microbes and our bodies.

In many ways, that relationship revolves around a specific protein called the farnesoid X receptor, or FXR, which helps maintain a healthy gut through its intimate relationship with bile acids...

In a world grappling with a multitude of health threats—ranging from fast-spreading viruses to chronic diseases and drug-resistant bacteria—the need for quick, reliable, and easy-to-use home diagnostic tests has never been greater. Imagine a future where these tests can be done anywhere, by anyone, using a device as small and portable as your smartwatch. To do that, you need microchips capable of detecting miniscule concentrations of viruses or bacteria in the air.

Now, new research shows it’s possible to develop and buil...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems Understanding at the Helmholtz-Zentrum Dresden-Rossendorf, Sandia National Laboratories (U.S.) and the French Alternative Energies and Atomic Energy Commission has introduced a simulation method that promises new insights into the Earth’s core.

The method, presented in the Proceedings of the National Academy of Sciences, simulates not only the behavior of atoms, but also the magnetic properties of materials...

Breakthrough in Zinc-based Rechargeable Batteries: A safer, sustainable alternative

Case Western Reserve University researcher advances zinc-sulfur battery technology. Rechargeable lithium-ion batteries power everything from electric vehicles to wearable devices. But new research from Case Western Reserve University suggests that a more sustainable and cost-effective alternative may lie in zinc-based batteries.

In a study published recently in Angewandte Chemie, researchers announced a significant step toward creating high-performance, low-cost zinc-sulfur batteries.

“This research marks a major step forward in the development of safer and more sustainable energy storage solutions,” said Chase Cao, a principal investigator and assistant professor of mechanical and aerospace engineering at Case School of Engineering...
