Early on, a lot of energy went into digitizing texts and creating online repositories like the Walt Whitman Archive. But second-generation projects are focusing on the interpretive possibilities offered by those digital resources. That has opened up lines of critical inquiry difficult to imagine in the predigital era.

Mahzarin R. Banaji , a Harvard prof, created a Web site to advance her scholarly research on prejudice. More than three million people so far have visited Project Implicit, which has expanded to offer a buffet of interactive tests — Banaji calls them "implicit association tests" — that claim to reveal people's hidden biases, attitudes, and beliefs. She says her research indicates that children as young as 3 have strong racial biases. Here you will have the opportunity to assess your conscious and unconscious preferences for over 90 different topics ranging from pets to political issues, ethnic groups to sports teams, and entertainers to styles of music. At the same time, you will be assisting psychological research on thoughts and feelings. Sessions require 10-15 minutes to complete. Each time you begin a session you will be randomly assigned to a topic. Try one or do them all! At the end of the session, you will get some information about the study and a summary of your results.

A Web site that tracks outbreaks of infectious diseases worldwide is sometimes proving faster than the Centers for Disease Control or the World Health Organization at detecting outbreaks, according to an article last week from Discovery News. The Web site called HealthMap was developed by Harvard Medical School employees John Brownstein, an assistant professor of pediatrics, and Clark Friefeld, a software developer. Mr. Brownstein says the Web site took off after Google.org, the technology company’s philanthropic arm, pumped money into the project nine months ago. HealthMap trolls through large amounts of data on the Internet to pinpoint the locations of diseases. The developers are planning to include detailed information on HealthMap about each outbreak.

A tool for creating digital sticky notes to highlight parts of web sites. Use to annotate things for yourself, or share your highlights with others.

The nanoHUB is a rich, web-based resource for research, education and collaboration in nanotechnology. The nanoHUB hosts over 1000 resources which will help you learn about nanotechnology, including Online Presentations, Courses, Learning Modules, Podcasts, Animations, Teaching Materials, and more. Most importantly, the nanoHUB offers simulation tools which you can access from your web browser, so you can not only learn about but also simulate nanotechnology devices. The nanoHUB also provides collaboration environment via Workspaces, Online meetings and User groups. Resources come from over 500 contributors in the nanoscience community, and are used by thousands of users from over 170 countries around the world.

HUBzero allows you to create dynamic web sites that connect a community in scientific research and educational activities. HUBzero sites combine powerful Web 2.0 concepts with a middleware that provides instant access to interactive simulation tools. These tools are not just Java applets, but real research codes that can access TeraGrid, the Open Science Grid, and other national Grid computing resources for extra cycles. HUBzero was created by researchers at Purdue University in conjunction with the NSF-sponsored Network for Computational Nanotechnology. The technology was originally developed to support nanoHUB.org, a national resource for nanotechnology simulation. It has since been extended to create science gateways for other scientific domains.
