There are several ways that you can keep up with newly published articles and tables of contents for new issues:
All of our databases--including Web of Science, SciFinder, Reaxys, PubMed, and Compendex + Inspec--allow you to save searches and get alerts when new records matching your searches are added to those databases. All offer email alerting options, and most offer RSS feeds.
To set up alerts, you'll need to create a user account for that database. Since SciFinder-n requires a user registration, you can set up their "keep me posted" alerts once you login and begin searching.If you want to keep up with the latest news on your topic, a good starting place would be Google News. You may also want to try Nexis Uni, which indexes newspapers and trade publications, or Academic Search Complete, where you can filter results to see magazine, newspaper, and trade publications.
Below are good places to start if you want to browse recent news topics for something of interest. There is also science and technology coverage in the more general news sources like CNN, BBC, The New York Times, The Guardian, NPR, and more. Most of these stories are tied to one or more recently published scholarly, peer-reviewed journal articles.
