Acerca de Big Science Small Pod

A compact guide to how your body works, powered by the world-class scientists of Virginia Tech’s Fralin Biomedical Research Institute. The Fralin Biomedical Research Institute at VTC is one of the nation’s fastest-growing academic biomedical research enterprises and a destination for world-class researchers. The institute’s scientists focus on diseases that are the leading causes of death and suffering in the United States, including brain disorders, heart disease, and cancer.

Can Fat Fight Diabetes?

Conventional wisdom tells us that, to be healthy, we should exercise and limit fatty foods. Exercise helps us lose weight, build muscle, strengthens our hearts and boosts how we take in and use oxygen for energy — one of the strongest predictors of health and longevity. But people with high blood sugar often don’t enjoy those benefits from exercise, especially the ability to use oxygen efficiently. For them, a new study [https://news.vt.edu/articles/2026/02/research_fralinbiomed_lessardketo.html?utm_campaign=fy26global&utm_source=bssp&utm_content=discoveries&utm_medium=podcast&utm_program=fbri] suggests the answer could be eating not less fat, but more. Exercise medicine scientist Sarah Lessard [https://fbri.vtc.vt.edu/people-directory/primary-faculty/lessard.html] explains her new study that examines how the keto diet might help people with diabetes and high blood sugar in the latest episode of Big Science Small Pod. “What we're really finding from this study and from our other studies is that diet and exercise aren't simply working in isolation,” she said. “There are a lot of combined effects. And so we can get the most benefits from exercise if we eat a healthy diet at the same time.”

What Makes Seizures Start?

Not all cases of epilepsy are the same. Some people suffer a few seizures, begin taking one of 30 or more epilepsy medications available, and live a typical life. But for about a half million U.S. children with treatment-resistant disease, it’s far worse. Their seizures keep coming, making them more likely to die young. They’re at greater risk for learning problems, social and emotional difficulties, and social isolation. Many of these epilepsies are caused by genetic mutations. Matthew Weston [https://fbri.vtc.vt.edu/people-directory/primary-faculty/weston.html], a neuroscientist at Virginia Tech's Fralin Biomedical Research Institute [https://fbri.vtc.vt.edu/], leads a team working to identify them. In the latest episode of Big Science Small Pod, Weston explains what happens in the brain during seizures and how his lab is researching their genetic roots to help develop new treatments for children. “My goal,” Weston said, “is to understand this in a way that has an … effect on patient care, focused on making these kids’ lives better.”

What Do You Do When Your Body Is Its Own Enemy?

Lining the vessels that carry blood and oxygen to your brain, there’s a protective filter than keeps bad stuff from getting out of the bloodstream and into the brain where it can do harm. It’s called the blood-brain barrier. But this feature becomes a problem when doctors need to get chemotherapy to a brain tumor. That protective barrier then stands between cancer and drugs that could treat it. Physician-scientist Cheng-Chia “Fred” Wu [https://fbri.vtc.vt.edu/people-directory/primary-faculty/wu.html] of the Fralin Biomedical Research Institute [https://fbri.vtc.vt.edu/] is investigating how to use sound to temporarily open that barrier to allow cancer drugs to reach brain tumors, like those caused by the highly lethal childhood cancer he treats, diffuse midline glioma. “As a radiation doctor, I point beams to fight cancer. That's what we do. Point and shoot,” Wu said. “Ultrasound is very similar to radiation in many ways … and so when I first learned about it, I just felt that this was a technology that can really be transformative.”

How Does a Brain Even Happen?

The cerebellum hasn’t gotten much love from brain scientists historically, but neurobiologists today are discovering how it works to control motor functions, and how problems in that brain region cause movement disorders. Research by ⁠Meike van der Heijden [https://fbri.vtc.vt.edu/people-directory/primary-faculty/vanderheijden.html]⁠, neurobiologist and assistant professor at the ⁠Fralin Biomedical Research Institute at VTC [https://fbri.vtc.vt.edu/]⁠, has found that disorders like dystonia and tremors are connected to changes in how nerve cells in the cerebellum communicate. Van der Heijden says the key to understanding what goes wrong in the cerebellum might lie in understanding normal development in children. “If we understand what is the timeline of that normal development,” she asked, “can we kind of use that to back engineer treatments … in adulthood.”

What If Sound Could Heal?

Sound has been harnessed for uses from medical imaging to SONAR. Now, scientists are exploring how ultrasound can be focused and used to treat conditions as varied as chronic pain, addiction, and cancer. Wynn Legon [https://fbri.vtc.vt.edu/people-directory/primary-faculty/legon.html] explains the evolution of focused ultrasound and how his lab is contributing to the growing list of whats the technology can benefit our health. Wynn Legon is an assistant professor at the Fralin Biomedical Research Institute at VTC [https://fbri.vtc.vt.edu/] in Roanoke. His lab studies the use of low-intensity focused ultrasound (LIFU). LIFU is an emerging form of noninvasive neuromodulation that uses mechanical energy to affect neuronal activity. The technology combines high spatial resolution with deep focal lengths providing unprecedented non-invasive access to the human brain. The enormous potential of low-intensity focused ultrasound stems from the ability to focus it through the intact skull to a millimeter-sized focal spot virtually anywhere in the brain. This makes it a powerful alternative to both invasive neurosurgical procedures and other non-invasive brain stimulation techniques.
