Introducing two free-access websites for research networking and outreach to be launched this week: Nature Reports Climate Change and Nature Reports Stem Cells. Aimed at researchers and at anyone else who is interested, both provide an editorial perspective of their fields through a combination of original journalism and commissioned comment, alongside archived material from other Nature publications. Both sites also facilitate community interactions through blogs: Climate Feedback and The Niche. These sites will develop further by way of community interactions and applications in the coming months. The original content of both is freely accessible.
