Research Help

Libraries have many resources for looking up topics of medical research, but you can also find good articles by looking online. Here are some examples to get you started.

Government sponsored websites (which usually end in .gov) provide links to research articles, statistics, information about government policies, spending priorities, and laws. Here are some examples:

  • British Medical Research Council News and Publications: Gives recent publications, news, and podcasts of research supported by the British government.
  • Indian Council of Medical Research: Publications and reports of Indian scientists. Includes some interesting information about traffic incidents and health issues.
  • National Science Foundation: U.S. Government agency which oversees the sciences and research. Find links to other U.S. agencies with information on agriculture, health and human services, the center for disease control, environmental services, Smithsonian museums, and space.

      Great idea mahnoor. My husband is a plant researcher, so I should certainly add those sorts of topics and I do have some on my other lists. We just went to see the new Food Evolution movie last night.

      If you get a chance to see it, I'd suggest that you go. Here are a couple of topics inspired by the movie: How did the GMO controversy get started? What can be done about the banana wilt which is causing the banana crops to be destroyed? How important was the Green Revolution? Do plants have feelings? Can the world be fed by organic crops alone?

      Thanks Donna--I find topics by looking at recent science research. There are so many new discoveries being made all the time! In fact, since all of my topics are taken from recent articles and research, that makes it easier for students to find sources if they need to use them in the paper. I probably need to add that in the article.
