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.

Outsmarting Influenza's Rapid Evolution
Philip Hunter | Jun 29, 2003 | 7 min read
Twice yearly, World Health Organization health officials meet to strategize against influenza, a malady that kills at least 250,000 people each year. In a chess match of sorts, they work to predict their opponent's next move, in this case by modifying vaccines to compensate for changes in the critical viral antigen hemagglutinin, which triggers the host's long-term immune memory. It takes several months to manufacture and distribute flu vaccines in sufficient quantities to inoculate vulnerabl

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
A Pioneer Presses Search For 'Other Side of Biology'
Gerald Edelman | Nov 13, 1988 | 4 min read
When I was a high school student, I came across Erwin Schrödingers What Is Life?. I still remember my exultant reaction—a combination of adolescent pride in feeling able to understand ideas considered beyond a young person’s means, and a genuine intellectual thrill engendered by the problems that Schrödinger addressed. Upon rereading the book, it appears to me that its major value was to provoke interest in a central problem of biology. Schrödinger’s question

Could Dad’s Mitochondrial DNA Benefit Hybrids?
Alejandra Manjarrez, PhD | Jan 20, 2022 | 7 min read
Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.
