A team of researchers working at Germany's Technische Universität Braunschweig has succeeded in using a previously known DNA origami construction technique to build a nanoantenna with a docking site. First published in the ...
Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...
