Engineering the Microbiome: CRISPR Leads the Way
Mariella Bodemeier Loayza Careaga, PhD | Mar 15, 2024 | 10+ min read
Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.
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
Stem cells for brain cancer

FEATUREThe Ecology of Tumors Stem cells for brain cancer BY PETER B. DIRKSNeural stem cell biology took off in 1992 when Brent Reynolds and Samuel Weiss, working at the University of Calgary, discovered that culturing mammalian brain cells in serum-free conditions (in EGF and bFGF), yielded clonally derived colonies of undifferentiated neural cells (neurospheres). This culture system demonstrated that cells within these colonies showed cardinal pr
Immune cell memory tracked
Victoria Stern | Oct 25, 2009 | 3 min read
A type of antibody long thought to have a minor role in immune system memory may actually be a key player, new findings suggest. Researchers tracked the antibody's function by imaging the immune system's B cells in the act of responding to a pathogen and developing into memory B cells, which can recognize an infectious agent years after first encountering it, they report in a study published online yesterday (October 25) in Nature Immunology.

Leukemia and Cancer Stem Cells
Irving Weissman and Michael Clarke | Apr 1, 2006 | 4 min read
FEATUREThe Ecology of Tumors Leukemia and Cancer Stem Cells BY IRVING WEISSMAN AND MICHAEL CLARKECancers and normal tissue stem cells have much in common: Both have self-renewal capacity, and both develop into differentiated progeny. But do true cancer stem cells exist? We believe that they do and that this realization will have a major impact on the understanding and treatment of cancers. Putative cancer stem cells can be recognized by three attr
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.
