PubMed Commons: Catalyzing Scientist-To-Scientist Interactions

Posted on by

LogoToday’s scientists find it tough to keep up with all of the latest journal articles, innovative methods, and interesting projects of colleagues in their fields. That’s understandable, because there are tens of thousands of journals, hundreds of conferences in major fields, dozens of emerging technologies, and huge geographic distances separating researchers who may share common interests. But science is increasingly a team sport—and it’s important to provide scientists with as many avenues as possible through which to interact, including commenting on each other’s work.

To encourage such exchanges, NIH’s National Center for Biotechnology Information (NCBI) recently developed PubMed Commons, a resource that gives researchers the opportunity to engage in online discussions about scientific publications 24/7. Specifically, this service allows scientists with at least one publication to comment on any paper in PubMed—the world’s largest searchable database of biomedical literature, with more than 3 million full-text articles and 24 million citations.

HeLa Cells: A New Chapter in An Enduring Story

One of the first things a biomedical researcher learns is that it’s very hard to grow most human cells in the lab for an extended period. In fact, once removed from the human body, most cells will either die immediately or reproduce only a limited number of times. That’s why it was so significant in 1951 that this barrier was overcome for the first time, using cancer cells taken from a 31 year old African American woman named Henrietta Lacks.
