A Weizmann team find new RNA switches for antibiotic resistance

Activity of a glucose-manufacturing gene in mouse liver tissue, viewed under a fluorescence microscope. A high concentration of mRNA (red dots) reveals that this activity is highest near a blood vessel (PP) that bathes the tissue in oxygen-rich blood, essential for glucose manufacture

Fits and spurts of gene expression help the liver cope with change

Stem cell colony with cells in the process of differentiation; from the lab of Dr. Jacob Hanna

Before anything else, a stem cell must first put the brakes on its “stem-cell” program

RiboSNitches: these RNA segments in the mother and father have slightly different sequences, but very different folding patterns

Folds in the RNA strands called RiboSNitches may affect protein function
