Using a new imaging agent that binds to tau protein and makes it visible in positron emission tomography (PET) scans, scientists at Washington University School of Medicine in St. Louis have shown that measures of tau are better markers of the cognitive decline characteristic of Alzheimer’s than measures of amyloid beta seen in PET scans.

Antibiotic-resistant bacteria most often are associated with hospitals and other health-care settings, but a new study from the School of Medicine indicates that chicken coops and sewage treatment plants also are hot spots of antibiotic resistance.

Two mouse models of Zika virus infection in pregnancy have been developed by a team of researchers at Washington University School of Medicine in St. Louis. The models provide a basis to develop vaccines and treatments, and to study the biology of Zika virus infection in pregnancy.

Signaling a potential new approach to treating diabetes, researchers at Washington University School of Medicine in St. Louis and Harvard University have produced insulin-secreting cells from stem cells derived from patients with type 1 diabetes.

Researchers at Washington University School of Medicine in St. Louis have found that some neurons in the orbitofrontal cortex assign value to options in everyday decision-making. The area’s neurons then can re-map to make different decisions when circumstances change.

Extended use of drugs to treat heartburn, ulcers and acid reflux may lead to serious kidney damage, including kidney failure, according to a study by researchers at Washington University School of Medicine in St. Louis and Veterans Affairs St. Louis Health Care System.

Consuming a high-fructose diet during pregnancy may cause defects in the placenta and restrict fetal growth, potentially increasing a baby’s risk for metabolic health problems later in life, according to research in mice and people by a team at Washington University School of Medicine in St. Louis.

A study led by Washington University School of Medicine in St. Louis describes a newborn screening test that identifies infants with Niemann-Pick type C, an often fatal condition in which cholesterol builds up and eventually destroys brain cells. Early detection may save lives and improve prospects for managing the disease.

When pre-med students head to China to attend classes at Fudan University and shadow doctors at different medical clinics, they gain a new perspective on medicine.

Feeding premature babies mostly breast milk during the first month of life appears to spur more robust brain growth, compared with babies given little or no breast milk, finds researchers from Washington University School of Medicine in St. Louis.
