When you join a newsgroup, you can find out what other people think about a new technology  or a specific scientific study. You can also receive information about other Internet sites dealing with science. You may make comments, ask questions, and receive answers about any scientific issue.  Newsgroups can also help you contact people who may be able to help you deal with a scientific problem that you're unable to solve. And if you've managed to solve a problem - use the newsgroups as a way to help others!
