The Advances section of Scientific American's December issue helps parents find educational toys for the holidays, pushes cooking into the future, remembers Steve Jobs, takes a look at faster-than-light neutrinos, investigates turtle yawning and more. For those interested in learning more about the developments described in this section, a list of selected further reading follows.
A Circuit in Every Cell
In their paper in Science, researchers at the California Institute of Technology describe how to construct biochemical circuits from scratch. They also described a DNA-based circuit that could play a simple memory game in the journal Nature. A follow up paper from researchers at MIT described a cell that can distinguish cancer cells from non-cancer cells.
Vitamins, Minerals and MicroRNA
Researcher Chen-Yu Zhang and her team at Nanjing University published a paper in the journal Cell Research in September on how micro-RNA can be transferred from our foods to our cells.
