Researchers crack the smile, describing three types by muscle movementThe smile may be the most common and flexible expression, used to reveal some emotions, cover others and manage social interactions that have kept communities secure and organized for millennia. But how do we tell one kind of smile from another?Social influences can override aggression in male mice, study showsA cluster of nerve cells in the male mouse's brain have been identified that, when activated, triggers territorial rage in a variety of situations. Activating the same cluster has no such effect on female mice.Lab-created mini-brains reveal how growing organ maintains neuronal balanceScientists can now explore in a laboratory dish how the human brain develops by creating organoids -- distinct, three-dimensional regions of the brain. Scientists coaxed early stage stem cells to create and fuse two types of organoids from different brain regions to show how the developing brain maintains proper balance of excitatory and inhibitory neurons.Scientists block evolution's molecular nerve pruning in rodentsResearchers investigating why some people suffer from motor disabilities report they may have dialed back evolution's clock a few ticks by blocking molecular pruning of sophisticated brain-to-limb nerve connections in maturing mice.Long-sought mechanism of metastasis is discovered in pancreatic cancerAn important discovery establishes a cause of metastasis in pancreatic cancer. Using organoids grown from patient tissues and transplanted in mouse models of the illness, the team pinpoints an epigenetic re-programming of gene enhancers that returns cancerous cells to a more primitive developmental state, dating back to the formation of the pancreas, in which cells multiply rapidly and are not yet anchored in tissue.Longstanding biological mystery of DNA organization now solvedStretched out, the DNA from all the cells in our body would reach Pluto. So how does each tiny cell pack a two-meter length of DNA into its nucleus, which is just one-thousandth of a millimeter across? The answer to this daunting biological riddle is central to understanding how the three-dimensional organization of DNA in the nucleus influences our biology, from how our genome orchestrates our cellular activity to how genes are passed from parents to children.Sticky when wet: Strong adhesive for wound healingA super-strong 'tough adhesive' has been created that is non-toxic and binds to biological tissues with a strength comparable to the body's own resilient cartilage, even when they're wet. Inspired by the glue produced by a slug, the double-layered hydrogel material demonstrates both high adhesion strength and strain dissipation, making it useful in a variety of medical applications.A new picture emerges on the origins of photosynthesis in a sun-loving bacteriaBiologists have gained important new insights by resolving with near-atomic clarity, the very first core membrane protein structure in the simplest known photosynthetic bacterium, called Heliobacterium modesticaldum (Helios was the Greek sun god). By solving the heart of photosynthesis in this sun-loving, soil-dwelling bacterium, the research team has gained a fundamental new understanding of the early evolution of photosynthesis, and how this vital process differs between plants systems.

ChromEMT: Visualizing 3D chromatin structure and compaction in interphase and mitotic cells
The chromatin structure of DNA determines genome compaction and activity in the nucleus. On the basis of in vitro structures and electron microscopy (EM) studies, the hierarchical model is that 11-nanometer DNA-nucleosome polymers fold into 30- and subsequently into 120- and 300- to 700-nanometer fibers and mitotic chromosomes. To visualize chromatin in situ, we identified a fluorescent dye that stains DNA with an osmiophilic polymer and selectively enhances its contrast in EM. Using ChromEMT (ChromEM tomography), we reveal the ultrastructure and three-dimensional (3D) organization of individual chromatin polymers, megabase domains, and mitotic chromosomes. We show that chromatin is a disordered 5- to 24-nanometer-diameter curvilinear ch...
