Why scratching makes you itch more

Turns out your mom was right: scratching an itch only makes it worse. New research from scientists at the Center for the Study of Itch at Washington University School of Medicine in St. Louis reveals that scratching causes the brain to release serotonin, which intensifies the itch sensation.

Genome sequenced of enterovirus D68 circulating in St. Louis

Researchers led by Gregory A. Storch, MD, at Washington University School of Medicine in St. Louis, have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children’s Hospital. Nationwide, the virus has spread rapidly in recent months and caused severe respiratory illness in young children, with some patients requiring hospitalization.

Human skin cells reprogrammed directly into brain cells

School of Medicine scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntington’s disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types.
