Hybrid Animals Are Not Nature’s Misfits
Ashley Yeager | May 1, 2021 | 8 min read
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.

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

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
Surpassing the Law of Averages

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

Recently the arena of human genome sequencing has seen a lot of heat generated by the entry of both commercial entrepreneurs and public consortia. Celera, a company formed by highly skilled and competent commercial organizations (TIGR and Perkin-Elm
