African fish called mormyrids communicate using pulses of electricity. New research from biologists at Washington University in St. Louis shows that a time-shifted signal in the brain helps the fish to ignore their own pulse. This skill has co-evolved with large and rapid changes in these signals across species.
Researchers at Washington University School of Medicine in St. Louis have created a COVID-19 vaccine candidate from a replicating virus. This experimental vaccine has proven effective at preventing pneumonia in mice.

A major U.S. study reveals large gaps between urban and rural patients in quality of care received after a stroke and rates of survival. In more rural areas, the ability of hospitals to deliver advanced stroke care is lower and mortality rates substantially higher, the research shows. The analysis, involving nearly 800,000 patients, was led by researchers at Washington University School of Medicine in St. Louis.
The U.S. Supreme Court’s decision June 18 that the Trump Administration cannot shut down the Deferred Action for Childhood Arrival (DACA) program will allow more than 700,000 “Dreamers” to worry a bit less and continue focusing on their jobs, education and futures, said an immigration law expert at Washington University in St.
Engineers at the McKelvey School of Engineering at Washington University in St. Louis have developed high-power, direct borohydride fuel cells that operate at double the voltage of conventional hydrogen fuel cells.
combination of IV and oral antibiotics can effectively treat invasive infections in people who inject illicit drugs, according to a study from Washington University School of Medicine in St. Louis. The findings mean that patients who do not wish to stay in the hospital for weeks of IV antibiotic treatment can leave and complete taking their prescribed antibiotics at home.
For the sake of research on brain and mobility, Nico Dosenbach, MD, PhD, an assistant professor of neurology at Washington University School of Medicine in St. Louis, wore a cast on his right dominant arm despite not having an injury. He then underwent hours of MRI scans while wearing the cast, and for two weeks before and after. The MRI scans found previously undetected brain pulses. The researchers also found that disuse of an arm causes the affected brain region to disconnect from the rest of the brain’s motor system within two days. However, spontaneous pulses maintain activity in the disused circuits until the region becomes active again when mobility is regained.
This paper — from the group that previously examined Martian dust storms — shifts focus to the electrochemical processes resulting from dust storms that may power the movement of chlorine, which is ongoing on Mars today.

When it fires, a neuron consumes significantly more energy than an equivalent computer operation. And yet, a network of coupled neurons can continuously learn, sense and perform complex tasks at energy levels that are currently unattainable for even state-of-the-art processors.What does a neuron do to save energy that a contemporary computer processing unit doesn’t?Computer modelling by researchers at Washington University in St.
Researchers at Washington University in St. Louis and the National Institutes of Health (NIH) have found that genes that confer the power to destroy tetracycline antibiotics are widespread in bacteria. But the researchers have also created a chemical compound that shields tetracyclines from destruction, restoring the antibiotics lethality. The findings indicate an emerging threat to one of the most widely used classes of antibiotics — but also a promising way to protect against that threat.
As a plant grows, it moves cellular material through transporter (motor) proteins along a highway system of microtubule tracks, moving cargo from its version of manufacturing sites to the cell wall construction zone. The Dixit lab found motor proteins necessary for track stability.
