by Lauren Hinkel, Massachusetts Institute of Technology Credit: Pixabay/CC0 Public Domain Neurodegenerative diseases—like amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease), Alzheimer’s, and Parkinson’s—are complicated, chronic ailments that can present with a variety of symptoms, worsen at different rates, and have many underlying genetic and environmental causes, some of which are unknown. ALS, in particular,...
INSTITUTE FOR BASIC SCIENCE IMAGE: CELLS WERE IRRADIATED WITH UV AND THE COLOCALIZATION OF XPA WITH UV DAMAGE SITES WAS VISUALIZED BY FLUORESCENCE MICROSCOPY. DNA DAMAGE IS HIGHLIGHTED BY RED ARROWS AND CO-LOCALIZATION OF XPA WITH UV DNA IS INDICATED BY YELLOW ARROWS. IN XPA-RPA32 MUTANT CELLS (M32-4), REDUCED XPA RECRUITMENT TO DNA DAMAGE WAS...
UNIVERSITY OF CALIFORNIA – SANTA CRUZ IMAGE: IN A STUDY OF EPIGENETIC INHERITANCE, RESEARCHERS CREATED EMBRYOS OF THE WORM C. ELEGANS THAT INHERITED EGG CHROMOSOMES PROPERLY PACKAGED WITH THE EPIGENETIC MARK H3K27ME3 AND SPERM CHROMOSOMES LACKING THE MARK. THE ONE-CELL EMBRYO ON THE LEFT INHERITED THE PINK CHROMOSOMES FROM THE EGG AND THE GREEN CHROMOSOMES...

by Technical University Munich Gut motility determines flows. (a) The gut is a muscular tube, whose motility patterns induce flows that affect the abundance of nutrients and bacteria. Abundances, in turn, feed back on motility. (b) Mathematical notation. (c) and (d) In vitro spatiotemporal map of the contraction amplitude observed for the small intestine of mice,...
