President Donald Trump has touted his new United States-Mexico-Canada Agreement as a way to boost the American economy. It may not, however, have any impact on one of his other campaign promises: reducing prescription costs for U.S. consumers, says a drug pricing expert at Washington University in St. Louis.

A new study in mice from the School of Medicine shows that viruses that target the nervous system can kill neurons in the gut that coordinate the process of moving waste along. Such viruses may be involved in causing people’s digestive woes.

Analyzing data from more than 400,000 people, researchers at the School of Medicine have found that consuming one to two drinks four or more times per week — an amount deemed healthy by current guidelines — increases the risk of premature death by 20 percent.

Michael Kinch’s new book, “Between Hope and Fear: A History of Vaccines and Human Immunity,” tells the story of the people behind vaccines and how the human body fights infection.

An MRI scan often generates an ocean of data, most of which is never used. When overlooked data is analyzed using a new technique developed at the School of Medicine, they surprisingly reveal how many and which brain cells are present – and show where cells have been lost through injury or disease. The findings could lead to new treatments for a variety of brain diseases.

The School of Medicine is joining a national research network aimed at diagnosing rare, previously undescribed diseases in patients whose conditions present as medical mysteries. The Undiagnosed Diseases Network is funded by the NIH and made up of 12 clinical sites and several research centers across the country.

Researchers at the School of Medicine have found that the same mutation that gives tuberculosis bacteria drug resistance also elicits a weaker immune response. The findings are published in Nature Microbiology.

The question of what constitutes “naturalness” — and consumers’ attitudes about it — lies at the heart of Washington University in St. Louis research from lead author Sydney Scott, assistant professor of marketing in the Olin Business School.

The signs of stress, anxiety or depression in a student may be easy to spot. The hard part is knowing what to do next. Kognito At-Risk for Faculty & Staff, an online simulation tool, will help Washington University in St. Louis faculty and staff lead effective discussions with struggling students.

A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells, according to new research at the School of Medicine.
