A team led by UT Southwestern researchers has identified how SARS-CoV-2, the virus that causes COVID-19, builds a structure called the RNA cap that's critical for successful viral replication.

In humans, a fertilized egg is no guarantee of reproductive success. Most embryos stop developing and perish within days of fertilization, usually because they have an abnormal number of chromosomes. Now, researchers at Columbia University Vagelos College of Physicians and Surgeons have found that most of these mistakes are due to spontaneous errors in DNA replication in the earliest phase of cell division.

Even before carbohydrates reach the bloodstream, the very sight and smell of a meal trigger the release of insulin.

As they grow, solid tumors surround themselves with a thick, hard-to-penetrate wall of molecular defenses. Getting drugs past that barricade is notoriously difficult.

Dental professionals require access to each patient's complete electronic health record – including laboratory test results and current prescriptions – so they can provide the best care possible; care that is safe for the patient, promotes preventive management and improves dental treatment outcomes.

Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances.

UT Southwestern researchers have discovered a molecular pathway that allows cells to sense when their lipid supplies become depleted, prompting a flurry of activity that prevents starvation.

Women who were pregnant during the recent Omicron surge were diagnosed with COVID-19 at a much higher rate than during previous phases of the pandemic, but were less likely to develop severe illness, a study by UT Southwestern and Parkland Health scientists found.

A team led by UTSW researchers has identified a molecule produced by male parasitic worms called schistosomes that prompts sexual maturity in females of these species.

Babies and toddlers who need a tracheostomy – a tube surgically inserted into their windpipe to help relieve breathing problems – are at a high risk of accumulating fluid behind their eardrum when on a ventilator.
