Four studies identify alternative origins for cells of the developing lymphatic system, challenging the long-standing view that they all come from veins.

How to troubleshoot sample preparation for cryo-electron microscopy, an up-and-coming structural biology technique.

From a rapid molecular test for COVID-19 to tools that can characterize the antibodies produced in the plasma of patients recovering from the disease, this year’s winners reflect the research community’s shared focus in a challenging year.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.

Reagents That Distinguish Th1 and Th2 cells Courtesy of R&D SystemsSchematic representation of cytokines influencing the development of antigen-activated naive CD4+ T cells into Th1 and Th2 cells. Editor's note: Although individual techniques are associated with specific researchers in this article, it should be noted that these investigators commonly use several different techniques to analyze T lymphocyte populations. The human body is constantly under siege. It must defend itself fr

"Lots of companies come out with media or reagents for this or that, and make a big splash, but they're all basically derivatives of traditional products," says Hayden Coon, a former National Institutes of Health re-searcher who is the founder of Human Cell Therapies Inc. of Chebeague Island, Maine.
