Last year I wrote about two brothers who are developing a better epi-pen -- one that's smaller and easier to carry, has a retractable needle, and has clearer label instructions. Eric and Evan Edwards both have life-threatening allergies and they started work on their device when they were still in college. Now they have a patent on their invention in partnership with Virginia Commonwealth University, where Eric is on leave from the medical school. The story can be found here in the Spring 2010 Dean's Discovery Report.
