by Menzies School of Health Research Squamous epithelial cell biofilms observed in bronchoalveolar lavage from children with protracted bacterial bronchitis or bronchiectasis. Representative maximum intensity projections of bronchoalveolar lavage stained with BacLight (A–B), fluorescent in situ hybridisation (FISH) probes (C–D), or haematoxylin and eosin (E–F). In BacLight images, DNA within intact (live) bacteria is stained...

By Rich Haridy February 01, 2022 New research homes in on a mechanism that could explain how brain iron levels increase with age Researchers at Northwestern Medicine have uncovered a mechanism they say contributes to the age-related accumulation of iron in the brain, a process some argue is a cause of cognitive decline. The study...
by Technical University Munich Dr. Monica Yabal, research group leader at the Institute of Molecular Immunology (front), and her team have discovered how inflammatory bowel disease leads to a chain reaction that upsets the gut microbiome. Credit: Astrid Eckert / TUM Chronic inflammatory bowel disease (IBD) is becoming increasingly widespread. Until now, however, the underlying...

In the new model, the striatum shows RNA and protein toxicities originated from the pure CAG repeats, which lead to neuronal damage. Credit: UCLA Health/Yang Lab Researchers at...
by Johns Hopkins University School of Medicine Unexpected heterogeneity of ribosomal RNA genes in human populations revealed by genome studies suggests potential variation in protein translation by the ribosomes. Credit: Wenjun Fan, Ph.D. A genome study undertaken by Johns Hopkins Kimmel Cancer Center researchers to look for variants in a gene considered a fundamental building...
“For the probationers that experienced serious mental illnesses, over two-thirds of them had experienced a significant number of traumatic events,” says Ashley Givens, an assistant professor in the University of Missouri School of Social Work, who interviewed 207 probationers with current mental illnesses about their trauma and analyzed how it was affecting them. In their study,...
