The document describes various types of network topologies including linear, mutual, telephone tree, and military squad networks. It discusses key network concepts like degree of separation and hubs. Degree refers to how connected a node is, and separation refers to the distance between nodes. Hubs are highly connected nodes that help connect other nodes. The document also discusses social networks and how examining hubs can help understand how diseases spread through networks.

Nodes with the largest numbers of links were actin (33 interactions), PtdIns(4,5)P2 (20), SLC9A3R2 (12), CALM (9), RDX (8) and Ca2+ (8). ERM proteins28, and binding was indeed stronger to threonine-to-aspartate mutation that mimics the acti phorylation (Fig. 5b and Supplementary Fig. 8).

With Bird Flu, 'Right Now, Anything Is Possible' April 19, 2013 5:36 AM by RICHARD KNOX Listen to the Story Morning Edition 4 min 22 sec ChinaFotoPress/Getty Images i An international dream team of flu experts assembled in China today. Underscoring the urgency that public health agencies feel about the emergence of a new kind of bird flu, the team is headed by Dr. Keiji Fukuda, the World Health Organization's top influenza scientist. Before he left Geneva, Fukuda explained the wide-open nature of
