Scientists are finding that on a molecular level organisms often function like social institutions. Some employ a military-like chain of command while in others important decisions are made by genetic middle managers. The more complex the organism, the less autocratic and more democratic the biological networks appear to be. In most cases, interactions between middle managers are more critical than actions from the “boss.”
YALE (US)—Similar to the way things work in social hierarchies, some molecular organisms give orders and some carry them out. Continue…

Candid camera at the nanoscale
“This is engineering at the ultimate atomistic limit,” says V. Ara Apkarian, who is leading a team attempting to record the first time-lapse images of single molecules. “There’s no question the tools that enable the observation and manipulation of one molecule at a time will be the pillars on which the field of nanotechnology will be built.”

Nanoalerts from healthy cells signal cancer
Vadim Backman, the study’s senior author, says nanoscale changes in both cancer cells and normal cells far away from the tumor site “are general phenomena in carcinogenesis and occur early in the process.”
