Yale scientists analogize the Linux call graph with the E. coli gene regulatory network in an open access PNAS article. Carl Zimmer explores the implications of network design versus evolution, suggesting that a more modular architecture in bacteria leads to a rugged (i.e. robust) system that does not "crash" like a computer.
Targeting the Good Cell: The Milwaukee Journal Sentinel covers the latest stem cell advances, built around a gripping 2008 series (1, 2, 3) about the competitive race to reprogram mature cells into functionally embryonic stem cells. [more inside]
The crowded, complex environment inside living cells makes understanding spatial relationships difficult for biologists. Now, 3D animation software Maya is being used not just for illustration, but to see how our intuition holds up. [more inside]
