Moving our clocks ahead one hour to shift into daylight saving time (which occurs at 2 a.m. Sunday) disrupts the body’s biological clock, affecting sleep patterns and how we function, according to a UT Southwestern Medical Center neuroscientist who researches circadian rhythms.

It’s almost that dreaded time of year, when spring and summer allergies can make life miserable for many.

Cell membrane protrusions called blebs that typically signify the end of life for healthy cells do the opposite for melanoma cells, activating processes in these cells that help them to survive and spread, a UT Southwestern study suggests.

How estrogen receptor-positive (ER+) breast cancer responds to hormone therapy may hold keys to understanding how it will respond to radiation therapy, and an experimental drug that increases the effectiveness of hormone therapy also overcomes radiation resistance in breast cancer, a study by UT Southwestern Medical Center researchers shows.

Researchers at UT Southwestern Medical Center have discovered how healthy bacteria can escape the intestine, travel to lymph nodes and cancerous tumors elsewhere in the body, and boost the effectiveness of certain immunotherapy drugs.

A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn’t receive this treatment, UT Southwestern researchers report in a new study.

High-Resolution Pharyngeal Manometry: A New Tool for Dysphagia Assessment, Biofeedback, and Progress Monitoring Melanie Turner Tice, M.S., CCC-SLP April 16, 2026 When modified barium swallow studies and fiber-optic endoscopic evaluations of swallowing are unrevealing, high-resolution pharyngeal manom…

Young adolescents face different challenges in pregnancy compared with their older teenage peers and adults that are sometimes exacerbated by high rates of obesity, a new study by UT Southwestern researchers suggests.

Automated external defibrillators (AEDs) are underutilized during cardiac arrest episodes despite laws in some states requiring their availability in high-risk areas such as athletic facilities, researchers at UT Southwestern Medical Center found. The devices can save lives by shocking the heart back into normal rhythm.
