Weathering Hantavirus: Ecological Monitoring Provides Predictive Model
Steve Bunk | Jul 4, 1999 | 7 min read
Photo: Steve Bunk Dave Tinnin, field research associate in the University of New Mexico's biology department, takes blood samples and measurements of rodents caught on the research station grounds. At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

(A-E) represent cells containing HAT-tagged proteins stained with the DNA dye, DAPI, and a monoclonal antibody against hemagluttinin, α-HA. At right the images are merged. (F-J) indicates cells carrying V5 tagged proteins. The bar equals 2 μm.Aliens sifting through the remains of a lost human civilization might puzzle over the function of a ladle.

Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
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

Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
An Ocean of Viruses
Joshua S. Weitz and Steven W. Wilhelm | Jul 1, 2013 | 10+ min read
Viruses abound in the world’s oceans, yet researchers are only beginning to understand how they affect life and chemistry from the water’s surface to the sea floor.

Could Dad’s Mitochondrial DNA Benefit Hybrids?
Alejandra Manjarrez, PhD | Jan 20, 2022 | 7 min read
Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.
