The process of selecting and blending genes to create artificial networks — synthetic biology — holds promise for many applications. But developing artificial networks takes time and is often frustrating. A research team has found a way to speed up the construction process by assembling a library of 20 versions of two gene promoters and a simple synthesis technique to create component libraries for synthetic library. This accessible method using combinatorial libraries removes the “tweaking” of gene network engineering.

Researchers have developed a way to release heat trapped inside billions of tiny semiconductor electronic circuits and channel it into the substrate, which is larger and can be more easily cooled. Their method exploits the electron scattering that occurs in non-suspended carbon nanotube transistors. This scattering causes a wave, or surface polariton, which is particularly strong in the near field zone above the substrate.
