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
New NSF Structure Reflects Broad Agency Reorientation
Scott Huler | Mar 15, 1992 | 6 min read
Date: March 16, 1992 Revamping of the biology directorate and creation of a social sciences unit aims to accommodate new trends in life sciences When Cora Bagley Marrett assumes full duties in May as the first assistant director of the new social, behavioral, and economic sciences division (SBE) of the National Science Foundation, she will give social scientists something for which they have long lobbied: their own voice in high-level NSF decisions. NSF announced the new directorate last Oc
Scientific Community Recognizing Link Between Ecology And Health
Karen Young Kreeger | Mar 3, 1996 | 9 min read
SENSE OF PROPORTION: "more needs to be done relative to the scale of the problem," remarks Stanford ecologist Gretchen Daily. The worldwide spate of emerging and reemerging infectious diseases in the first half of this decade has prompted a growing recognition of the connection between global climate change and human health. Individual researchers from such disparate disciplines as epidemiology and public health, ecology, virology, climatology, nutrition, and biomedicine have directly addresse
Many Disciplines Focusing On Fungus
Myrna Watanabe | Apr 17, 1994 | 5 min read
Although the field traditionally has branched into the study of fungi species that cause disease, mycologists say their field now encompasses molecular biology, ecology, chemical-extraction techniques, and other specialties and skills not usual for the traditional mycologist. The research emanating from laboratories studying fungi is diverse, including investigations of biological control of pest plants, production of new strains of

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.
