A cross section of a mouse liver lobule under a fluorescence microscope. The middle layer reveals an abundance of messenger RNA molecules (white dots) for the gene encoding hepcidin, the iron-regulating hormone

Tracking gene expression patterns for 20,000 genes in 1,500 cells revealed a mosaic of activities 

gene editing in single cells

A new combined method may finally give scientists a tool fine enough to probe life’s most nuanced processes

A “one-stop,” computer-design “shop” for stabilizing problematic proteins

Stress-coping molecule Urocortin-3 (green) and its receptor, CRFR2 (red),

Weizmann Institute scientists show how a molecule in the mouse’s brain regulates social behavior

Bones of mice at different ages, imaged with three-dimensional computer tomography. A core element at the center of the bone (highlighted in different colors) enabled the scientists to align different bones for comparison

How do bones retain their proportions as they grow? 

Gene expression of schizophrenia-related genes. 1,028 genes with very similar expression profiles are shown, one to a row, and 480 samples are arrayed in the columns. Red-to-blue shows the strength of the gene's expression level, red being stronger

New research reveals a cluster of genetic “typos” that may increase the risk of schizophrenia

Algorithm-generated comparisons among the genomes of cells from 450 tissue samples: The analysis revealed a striking similarity (red colors, upper right rectangle) in tRNA signatures among cancerous cells and healthy dividing cells, as well as a degree of similarity among the non-dividing cells (red colors, lower left rectangle), whereas no such similarity (blue) was found when dividing cells were compared with non-dividing ones
