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.
The Genetics of Society

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

To understand how memories are formed and maintained, neuroscientists travel far beyond the cell body in search of answers.
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
Recent Trials for Fragile X Syndrome Offer Hope

Courtesy National Science Foundation Headlines on the morning of December 14, 2000, trumpeted the end of a presidential election that promised to go on forever. But if California Institute of Technology molecular biologist Elliot Meyerowitz had his way, the front page would have read differently: "Plant Genome Sequenced" at the top, then, lower down, "Election Decided - See Page 2." In a tour de force that capped a year of genome blockbusters, European, Japanese, and American scientists complet

Genetic Parasites and a Whole Lot More

With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
We Must Try To Bridge The Gap Between Biological And Chemical Sciences
Arthur Kornberg | Jul 24, 1988 | 8 min read
Chemical language has great asthetic beauty and links the physical sciences to the biological sciences. Unfortunately, the full use of this language to understand life processes is hindered by a gulf that separates chemistry from biology. This gulf is not nearly as wide as that between the humanities and and sciences, on which C.P. Snow focused attention. Yet, chemistry and biology are two distinctive cultures and the rift between them Is serious, generally unappreciated, and counterproductive.
