•Science's Next Wave: http://nextwave.sciencemag.org/

It's not only cells of the immune system that are faced with decisions, and for those decisions relating to career choice, Science's Next Wave web site could be a good place to start. This career-development resource, which is updated weekly, aims to enable you to find out about the range of options that are open to you at various stages of your career, including research and non-research jobs, whether in academia, industry or elsewhere. Articles provide expert advice from individuals who have followed particular career paths, as well as the latest news from the science job market.

The site is helpfully organized so that recent articles can be found through the country homepages, which bring together news from each region (although homepages for some countries are not available), or through special-focus portals. These portals include the 'Career Development Center', which contains news and feature articles, and a search facility, which allows visitors to search for jobs in academic research or for grants, as well as 'The Grant Doctor', where questions about grants and fellowships are answered. The 'Postdoc Network' includes articles covering many issues that are of importance to postdocs, as well as career-development news, and it is a place where postdocs can raise concerns about their career needs or find the answers to their questions.

Next Wave's Career Resources Library is a useful archive of previously published articles divided into sections, including those specifically for graduate students and for individuals who are interested in career transitions or science policy.
