This coming June, the NIH Office of Medical Applications of Research is holding a three-day course entitled "Medicine in the Media: The Challenge of Reporting on Medical Research." The agenda is here. Amazingly, course registration is free, and meals and lodging are provided - all you have to do is get yourself to Bethesda, Maryland.
What's the catch? Well, the application process is competitive; only 50 spots are available, and in recent years, only 1/3 to 1/2 of applicants have gotten in. So if you're a science journalist whose "primary target audience is the general public" - and yes, that includes bloggers - get started on the application here, before the inevitable holiday craziness makes you forget all about it. The deadline is January 30. Good luck!
