Researchers map structure of key chromatin-remodeling complex

Northwestern University researchers have mapped a group of proteins that play a critical role in both gene expression and repairing damaged DNA. By understanding this protein complex, called SWI/SNF, researchers hope to better ...

Condensins mutually interact to fold DNA into a zigzag structure

DNA in a cell is comparable to tangled spaghetti strands on a plate. To be able to divide DNA neatly between the two daughter cells during cell division, the cell organises this tangle into tightly packed chromosomes. A protein ...

How cells get moving

Archaea, bacteria and eukaryotes are what biologists call the three domains of life. Of these three, archaea form an important link within the evolutionary theory. They are the direct ancestors of eukaryotes, but resemble ...

Methods in belowground botany

Plant root systems play a crucial role in ecosystems, radically impacting everything from nutrient cycling to species composition. Despite their importance, scientists are just beginning to develop the tools to understand ...

Gold for iron nanocubes

One of the major challenges in nanotechnology is the precise control of shape, size and elemental composition of every single nanoparticle. Physical methods are able to produce homogeneous nanoparticles free of surface contamination. ...
