Genome Spotlight: Tubifer cardinalfish (Siphamia tubifer)
Christie Wilcox, PhD | Apr 28, 2022 | 3 min read
These tiny reef fish harbor luminous bacteria, and the chromosome-level assembly of the species’ genome may facilitate the duo’s use as a vertebrate model for symbiosis.

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. 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
"Big Cross" Lands Sticklebacks in the Spotlight
David Secko | Nov 7, 2004 | 5 min read
Marine threespine sticklebacks haven't morphologically changed in an estimated 10 million years, but their freshwater offshoots show no signs of slowing down. These 5-cm-long, freshwater fish have undergone a recent evolutionary change, variably losing their calcified body armor and retractable pelvic and dorsal spines. Remarkably, isolated marine and freshwater sticklebacks can be hybridized in the laboratory, a fact that is allowing researchers to analyze the genetics behind their natural dive
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

Interdisciplinary Study Of Nonhuman Primates Gains Ground
Steve Bunk | May 10, 1998 | 8 min read
Date: May 11, 1998 Author: Steve Bunk Do apes have feelings? Do they recognize and understand emotions? Behavioral and biomedical scientists are beginning to put aside old differences concerning such questions and combine their efforts to shed new light on what nonhuman primates may reveal about human evolution. A national leader in this emerging interdisciplinary approach is the Yerkes Regional Primate Research Center at Emory University in Atlanta. In September of 1977, the university establ

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b
