Mafia Wars
Jef Akst | May 31, 2010 | 10+ min read
An increasing amount of data is showing that the cellular battle between pathogens and hosts needs much more than a simple military metaphor to describe it—think undercover infiltration, front organizations, and forced suicide.
Flow Cytometry: It's Not Just For Immunologists Anymore
James Kling | Jun 22, 1997 | 9 min read
A low-profile child of the '60s, flow cytometry didn't capture the imagination of most researchers until the early 1980s. The decade saw the birth of the AIDS epidemic, and as attention focused on HIV, researchers needed a method to accurately and reproducibly characterize immune cells. Flow cytometry was suddenly thrust into the spotlight.

Taking The Measure Of The Message
Laura De Francesco | Nov 22, 1998 | 9 min read
Date: November 23, 1998Product Comparison Getting a measure of even a single RNA species has never been easy. Every few years, a new technique comes along--Northerns, ribonuclease protection assays, RT-PCR--that makes the task only incrementally easier. But a quantum leap in technology took place just a few years ago with the introduction of cDNA arrays, and suddenly not just one but hundreds to thousands of target nucleic acids can be analyzed simultaneously and precisely. Since then, array te
