Pain is meant to be a defense mechanism. It creates a strong sensation to get us to respond to a stimulus and prevent ourselves from further harm. But, sometimes injuries, nerve damage, or infections can cause long-lasting, severe bouts of pain that can make daily life unbearable.

What if there was a way to simply turn off pain receptors? UNC School of Medicine researchers Bryan L. Roth, MD, Ph.D., the Michael Hooker Distinguished Professor of Pharmacology, and Grégory Scherrer, PharmD, Ph.D., associate professor of cell biology and physiology and the UNC Neuroscience Center, have just proven that it is possible.

Using a tool designed by Roth in the early 2000s, the labs have created a new system that reduces acute and tissu...

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...
