From http://www.healthmap.org/about.php: 

HealthMap brings together disparate data sources to achieve a unified and comprehensive view of the current global state of infectious diseases and their effect on human and animal health. This freely available Web site integrates outbreak data of varying reliability, ranging from news sources (such as Google News) to curated personal accounts (such as ProMED) to validated official alerts (such as World Health Organization). Through an automated text processing system, the data is aggregated by disease and displayed by location for user-friendly access to the original alert. HealthMap provides a jumping-off point for real-time information on emerging infectious diseases and has particular interest for public health officials and international travelers.

There's a good article about it on Webware. 

David Rothman publishes a good medical librarianship web site/blog.

Nature Network is the online meeting place for you and fellow scientists to gather, talk and find out about the latest scientific news and events. Science is an international endeavor and deserves a global stage for discussion. Scientists can also benefit from interactions at the local level. That's why you'll see an increasing number of local city hubs on Nature Network, starting with Boston and London.

What you can do on Nature NetworkNature Network is completely free. Here's what you can do on it:

• Create your own personal profile page and describe yourself and your research.
• Set up a group for your lab, department or institution. Or you can form a topic-based group, such as an RNAi, climate change, or nanotechnology group.
• Join other groups and have discussions with group members.
• Build your own online network of likeminded people.
• Become a blogger and give us your take on what's going on in your field or in the broader world of science; post comments on other people's blogs.
• On the city pages, search and browse our comprehensive listing of all upcoming seminars and conferences. We aim to list everything from niche meetings to screenings of science-based films and plays. You can even post your own events.

• Browse local jobs listings.

Note that the "EBM Librarian," developed by a team including the Biomedical Libraries' own Karen Odato, is "recommended." Nice!
