Soldiers spend a lot of time wearing body armor. The added weight takes a toll on their shoulders and back, contributing to one of the most common injuries reported by U.S. Army soldiers: back overuse. Vanderbilt researchers have developed a two-pound wearable device that redistributes 90 percent of that weight to the wearer’s hips while standing, walking and sitting—and lets soldiers retain their full agility and freedom of movement. Associate Professor Karl Zelik, senior research engineer Chad Ice and Ph.D. graduate Paul Slaughter published the study. Read More

While using an ice pack to ease pain is nothing new, a Vanderbilt team has taken the concept high-tech. Associate Professor Leon Bellan leads the group that has developed a cold-triggered “depot”—an implantable device that releases medication from within the body on demand. This shows promise on two fronts: Patients can release the medication simply by putting an ice pack over the implant, and locally effective NSAID drugs can be used instead of more addictive opioids.

A new PBS Kids series created to help children better understand the impact of weather and climate took instructional cues from Jeremi London, associate provost for academic opportunity and associate professor of mechanical engineering, who played a role in the show’s development. Read More

Vanderbilt supports new faculty every step of the way—by connecting them with senior faculty who serve as mentors, observe their classes and provide valuable feedback, and proofread their grant proposals to make them stronger. These professors who joined Vanderbilt in the past few years shed light on how the university has helped them succeed.  Read More

Gastroesophageal reflux disease, or GERD, plagues millions of people. Vanderbilt researchers led by Assistant Professor Xiaoguang Dong have developed a soft robotic valve that can seal off the lower esophagus from the stomach, keeping gastric acid where it belongs. Then when the patient eats or drinks, the valve, which is implanted in concert with a stent, can be opened with a wearable external magnet. “This platform holds promise not only for treating GERD, but also for managing other sphincter-related disorders,” said co-author and Assistant Professor Yuxiao Zhou.

Political propaganda and artificial intelligence–driven misinformation are infiltrating social media accounts, and Americans need to do something about it. That’s the warning revealed in research from two Vanderbilt professors and discussed on this special episode of the Quantum Potential podcast. Read More

Much of the human brain is still a mystery, largely because it’s pretty difficult to see what’s going on in there. Assistant Professor Daniel Gonzales and the team in his lab are working to make that easier. They’re using experimental platforms that record brain activity with unprecedented precision on all levels. It works on everything from whole-brain networks to individual synapses—tiny gaps between brain cells that are one-tenth the width of a human hair. “We can … really detail pictures of brain activity during learning,” Gonzales said. “And then we can apply that to study diseases that degrade learning.” Read More

Road closures are a pain—and sometimes they’re not even supposed to be happening. A project by senior research scientist Ayan Mukhopadhyay is working to develop a system—SENTRY—that uses AI to help city inspectors find and address unauthorized road closures in Nashville. “The system has the potential to save millions in unpaid permit fees, reduce external inspection costs and minimize disruptions for residents, commuters and local businesses,” Mukhopadhyay said. His research is supported by a $697,000 grant that's part of NSF's CIVIC Innovation Challenge. Read More

Josh Caldwell, professor of mechanical engineering and Director of the Interdisciplinary Materials Science graduate program at Vanderbilt University, and Alex Paarmann of the Fritz Haber Institute, led an international collaborative research project that successfully demonstrated the confinement of terahertz light to nanoscale dimensions using a new type of layered material. This could lead to improvements in opto-electronic devices such as infrared emitters used in remote controls and night vision and terahertz optics desired for physical security and environmental sensing.
