What can happen if you don't get enough? What is enough? TPR's Bonnie Petrie talks about her own March madness with a Boston University doctor who has been studying this chemical — that isn't actually a vitamin — for decades.

Exercise can improve function and slow disease progression in people with Parkinson's disease, but why? A UT Health San Antonio researcher is studying patients who exercise and play virtual reality games to see if she can figure out the answer.

A study of two groups of 70-year-olds found that branched-chain amino acids combined with exercise improve physical function and quality of life. Exercise alone did not.

Congenital heart disease can often be detected at the mid-pregnancy ultrasound, which dramatically improves outcomes. But too many people don’t get adequate prenatal care.

From COVID-19 research to Parkinson's disease therapies, these statistical experts turn numbers into answers, helping doctors make evidence-based decisions that improve patient care.

Many medications ease the constellation of symptoms that define Parkinson's disease, but the only treatment that slows the progression of the neurological movement disorder can't be purchased at a pharmacy. It's high-intensity, cardiovascular exercise, like boxing, and it's changing lives.

The answer to why some people develop obesity, diabetes, and other metabolic disorders, and why some people respond so well to medicines like Ozempic, might lie in those signals. UT Health San Antonio endocrinologist Dr. Marzieh Salehi is studying that communication in patients with spinal cord injury.

Jannine Cody, PhD, founded and leads the Chromosome 18 Clinical Research Center, which has revolutionized the understanding of and care for disorders caused by alterations in chromosome 18 in humans.

Health and Human Services Secretary Robert Kennedy Jr. has ordered a dramatic reduction in the number of vaccines recommended by the Centers for Disease Control.
