The very rare animals that reproduce asexually — only about one in 1,000 of all living vertebrate species — are thought to be at an evolutionary disadvantage compared with their sexually reproduced counterparts. But that theory doesn’t hold true regarding the Amazon molly, an all-female fish species that has thrived for millennia in the fresh […]
The current influenza outbreak – the worst across the United States in nearly a decade – is worrisome but still far less dire than a pandemic flu, which could kill millions. Such pandemics are exceedingly difficult to predict, but new research at Washington University School of Medicine in St. Louis offers details about flu viruses […]
A new anti-cancer strategy wields light as a precision weapon. Unlike traditional light therapy — which is limited to the skin and areas accessible with an endoscope — this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School of Medicine in St. Louis. […]
Respiratory infections peak during the winter months, and most people recover within a few weeks. But for those with a rare genetic lung disease, the sniffling, coughing and congestion never end. The tiny hairlike structures called cilia that normally sweep mucus through the airways don’t work properly in people with what’s known as primary ciliary […]
More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain’s ability to repair damaged neurons and […]

Radiation therapy often is used to treat cancer patients. Now, doctors at Washington University School of Medicine in St. Louis have shown that radiation therapy — aimed directly at the heart — can be used to treat patients with a life-threatening heart rhythm. They treated five patients who had irregular heart rhythms, called ventricular tachycardia, […]
Research led by Washington University School of Medicine in St. Louis has prompted the World Health Organization (WHO) to issue new treatment guidelines aimed at accelerating global elimination of lymphatic filariasis – a devastating tropical disease. An estimated 70 million people worldwide are infected with lymphatic filariasis, a parasitic disease spread by mosquitoes. The disease […]
Diabetes is known to increase a person’s risk of kidney disease. Now, a new study from Washington University School of Medicine in St. Louis suggests that the converse also is true: Kidney dysfunction increases the risk of diabetes. Further, the researchers deduced that a likely culprit of the two-way relationship between kidney disease and diabetes […]
Patients who go to the emergency room (ER) with chest pain often receive unnecessary tests to evaluate whether they are having a heart attack, a practice that provides no clinical benefit and adds hundreds of dollars in health-care costs, according to a new study from researchers at Washington University School of Medicine in St. Louis. […]

Sebastian Nasamu, an MD/PhD student at Washington University School of Medicine in St. Louis, battled successive bouts of malaria as a child growing up in Ghana. He survived – but decided long ago to commit himself to eradicating the disease. The possibility that his work could lead to a treatment is the reason he goes […]
In 1978, during the infancy of the AIDS epidemic, reports about isolated cases of gay men suffering from a rare lung infection and an aggressive cancer began trickling in to the Centers for Disease Control and Prevention (CDC). That same year, Rupa Patel was born in the Midwest to immigrants from rural Indian villages. While her parents […]
“This is the beginning of a new era of cancer therapy,” said Washington University oncologist Armin Ghobadi, MD, an assistant professor of medicine, who treats patients at Siteman. “With CAR-T cell therapy, we can take patients’ own cells and turn them into a powerful weapon to attack cancer. It’s a highly personalized, innovative therapy and one […]
An estimated 120 million people worldwide are infected with lymphatic filariasis, a parasitic, mosquito-borne disease that can cause major swelling and deformity of the legs, a condition known as elephantiasis. Health-care workers rely on leg measurements to assess the severity of the condition. However, measuring legs that are severely swollen often proves cumbersome and impractical. […]
Outdoor air pollution has long been linked to major health conditions such as heart disease, stroke, cancer, asthma and chronic obstructive pulmonary disease. A new study now adds kidney disease to the list, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System. […]
Warfarin is a blood thinner that is commonly prescribed to patients to prevent life-threatening blood clots. Despite its longtime use, warfarin remains tricky to dose because a person’s genetic makeup influences how the drug is processed in the body. Too much warfarin can cause internal bleeding; too little warfarin fails to prevent blood clots. Now, […]
There’s good fat and bad fat in our bodies. The good fat helps burn calories, while the bad fat hoards calories, contributing to weight gain and obesity. Now, new research at Washington University School of Medicine in St. Louis has identified a way to convert bad, white fat into good, brown fat, at least in […]
Breast cancer that spreads often infiltrates bone, causing fractures and intense pain. In such cases, chemotherapy is ineffective because the environment of the bone protects the tumor, even as the drug has toxic side effects elsewhere in the body. Now, scientists at Washington University School of Medicine in St. Louis have developed a nanoparticle that […]
Brazil and other areas hardest hit by the Zika virus – which can cause babies to be born with abnormally small heads – are also home to dengue virus, which is spread by the same mosquito species.
A new study of children living in inner-city areas and at high risk of developing asthma suggests that exposure to certain pet and pest allergens in infancy lowers the risk of developing asthma by age 7. The research also provides evidence that the type of bacteria hitching a ride on the allergen particles is an […]
Researchers at Washington University School of Medicine in St. Louis are recruiting volunteers for a national study that is exploring whether strategies to improve cardiovascular health also reduce the risk of dementia in those at risk for Alzheimer’s disease.
The roots of chronic itching have long remained a mystery. Meanwhile, those with the condition suffer from an unrelenting and sometimes debilitating urge to scratch.
