There are many science magazines that will allow you to remain in touch with the developments. I suggest you regularly try Google News and seeing the latest updates there. You will get all the information and the latest developments from all the sites possible. This means even if you miss something from a certain place, you can always have access from other sites.
If you want to know about astronomy, official site of NASA will do. You can look for other scientifc news in headlines in Google or MSN or Yahoo, etc. It is better to search it.
