Scientific publisher Nature Publishing Group has launched two new networking sites for scientists and the scientific information community. In the last two years Nature has trail blazed into networking to compliment its publishing activities.

Nature Network is a free online space that offers those in science a place to discover scientists working in the same fields, tag content, share information with communities and point other researchers towards their blogs and homepages.

Nature is launching two localised sites, Nature Network London and Nature Network Boston for the said cities.
