Study suggests private NICU rooms may influence preemies’ development

Premature babies often spend their first months of life in neonatal intensive care units (NICUs) — environments that, in recent years, have seen transformations, with hospitals adding private rooms to NICUs in place of open wards. But research at the School of Medicine adds new information to the discussion over what is the optimal setting for infants in the NICU. Shown is the study’s first author, Bobbi Pineda, PhD, in the NICU at St. Louis Children’s Hospital.

Genetic errors identified in 12 major cancer types

By analyzing the DNA in more than 3,000 tumors, scientists led by Li Ding, PhD, at The Genome Institute have identified 127 repeatedly mutated genes that likely drive the growth of a range of cancers in the body. The discovery sets the stage for devising new diagnostic tools and more personalized cancer treatments.

Scientists unravel mechanisms in chronic itching

New research at the School of Medicine shows that chronic itching, which can occur in many medical conditions, is different from the urge to scratch a mosquito bite. Chronic itching appears to incorporate more than just the nerve cells that normally transmit itch signals. In the image shown, researchers identified elevated signaling (in red) in nerve cells involved in both itch and in pain.
