Researchers have created a material that manufactures the proteins responsible for cell movement, without needing intact living cells. By embedding cell-free gene expression into a thin sheet of protein filaments, they were able to make the material wrinkle, rise into blister-like shapes and break into bundles that flow around one another.

A quick squeeze helps CRISPR turn skin cells into neurons more efficiently
Human cells hold about two meters (6.6 feet) of DNA, folded and compacted to fit inside a nucleus. That packing is essential for life, but it creates a problem for scientists. Some of the genes that control a cell's identity are buried so deep in tightly packed DNA that gene-targ
