In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.

The DNA in the cell nuclei of higher organisms is tightly coiled around protein complexes called nucleosomes, which repress gene expression. Researchers in Germany have now developed a model that ...

In both physics and chemistry, the mesoscopic scale refers to the length scale on which the properties of a material or phenomenon can be studied, without entering into a discussion about the behavior ...
