New maps of mouse brains reveal patterns of myelin formation

Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to construct new maps of mouse brains showing a precise location of more than 10 million cells called oligodendrocytes.

Study reveals what drives PFAS exposure in firefighters and how risks may be reduced

A large U.S. firefighter cohort study identified personal, occupational, and department-level predictors of serum PFAS concentrations, highlighting both modifiable exposures and persistent background sources. Some protective practices, blood or plasma donation, and drinking water sources were associated with differences in specific PFAS analytes, although causal relationships require further longitudinal study.

Neural circuits in flies provide insights into human eating

Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things at certain times, and sweets at other times? The answers, according to new neuroscience research at the University of Delaware, may lie in a tiny brain in an organism you might not expect.
