In keeping with its tradition of breaking new ground in scientific publishing, Science was a pioneer in moving journal content online, beginning the shift in 1995 with the start of Science Online, of our online science jobs site, Science Careers, and of our career development site for young scientists, Next Wave (which has now been merged with the Careers site). Since then, our Web family has grown in scope:

• The flagship Science Magazine site provides the full text of the journal’s news stories, research reports, and commentary articles in a searchable database, enhanced by additional information, links, multimedia, and user services, as well as a database of scientific-product information.
• The Science Express area of the site posts selected original, peer-reviewed hot research weeks ahead of its print publication date, thereby making the work available to the scientific community within a matter of days after manuscript acceptance.
• The Science Now online daily news service brings brief breaking news stories from the award-winning reporting staff of Science to your computer desktop every business day.
• Science’s Signal Transduction Knowledge Environment (STEK)offers original review articles, protocols, teaching resources, and other resources on cellular signal transduction — the study of how cells communicate through chemical signals, an interdisciplinary field with implications in biological areas ranging from embryo development to cancer research. A unique feature of STKE is its Connections Maps, which graphically depict the chemical pathways of cell signaling.
• The Science of Aging Knowledge Environment(SAGE KE) is a centralized bank of information about the aging process for aging-field researchers, featuring news, reviews, commentary, a gene database, and other tools. (An external sister Web site to SAGE KE, SAGE Crossroads , offers resources on the ethical, political, economic and societal ramifications of present and future research on aging, for laypeople, policymakers, and the media.)
• Finally, the Science sites include the world’s best destination for information on science jobs, funding, and career-building: ScienceCareers.org. Extensively redesigned and rebuilt in the fall of 2005, ScienceCareers.org now combines the best of Science’s Next Wave, our pioneering career information site for young scientists; GrantsNet, our biomedical funding search network; and Science Careers, our long-standing job-hunting and networking headquarters with job listings, résumé postings, a searchable meetings-and-events database, and more.
