Electron microscopy for cellular transcription :
Not saying that microscopy pictures are always the most instructive, but I was pleasantly surprised to see that the American Society for Cell Biology has a nice collection of images and videos available free for us online (and thankfully with decent descriptions/pointers).

I’ve been reading a bit more on biological networks lately (specifically those within the cell). There are a lot of interesting open questions and results that draw from molecular biology, network theory, and statistical physics. A few reviews stand out:
A recent book on the application of complex networks tools to biological systems and vice versa has caught my eye: Analysis of Biological Networks by Bjorn Junker and Falk Schreiber. It seems to cover “middle ground” and contextual information very relevant for someone interested in the connection.
Update: this book is alright, but I feel later posts point to better papers.
