Ants Share Pathogens for Immunity
Sabrina Richards | Apr 3, 2012 | 4 min read
A new study shows that grooming by ants promotes colony-wide resistance to fungal infections by transferring small amounts of pathogen to nestmates.

According to Protocol
Barbara Cunningham | Apr 15, 2001 | 8 min read
Nearly all scientists involved in basic biomedical research are familiar with the "Red Book" (Current Protocols in Molecular Biology)1 and Molecular Cloning: A Laboratory Manual.2 These well-known, time-tested books are still considered "bibles" in research laboratories, containing a wide range of basic techniques used by most life scientists. However, as scientific studies and experimental designs become more intricate and specialized, so do the techniques involved. As a result, detailed, "spec
Surpassing the Law of Averages

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Microcolumns Collapse in Alzheimer's Brain Tangles and plaques are hallmarks of the Alzheimer's brain. Thanks to a technique borrowed from statistical physics, researchers from Boston University, the University of Minnesota, and Bar-Ilan University in Israel have quantified another sign: microcolumns of 11 neurons that are noticeably diminished in the Alzheimer's brain, and less so in the related condition Lewy body dementia. Using brains from a brain bank, the researchers probed a part of the
