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.

Investigating Molecular Motors Step by Step
Jeffrey Perkel | Mar 14, 2004 | 10+ min read
Thom Graves MediaThe audience, several hundred biophysicists strong, was not expecting a James Brown impersonation. But there he was: Physiologist Yale Goldman, keynote speaker on motility at the Biophysical Society's annual meeting, doing his "asymmetric hand-over-hand motility dance with a limp" to tinny strains of "Papa's Got a Brand New Bag." And while Goldman, who eschewed Brown's trademark, over-the-top couture for understated, Ivy League-issue khakis and blue blazer, won't star on MTV any

Molecules, cells, or vertebrates—when individuals move and act as a single unit, surprisingly complex behaviors arise that hint at the origins of multicellularity.

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
Life With Selfish Genes: The Evolution Of Richard Dawkins
Bernard Dixon | Nov 27, 1988 | 9 min read
On the other hand, Dawkins’ forays into the popularization of evolutionary processes also made the zoologist the target of creationists and even a few biologists. In particular, his critics argue that if the gene is indeed “selfish”—that is, more important than the individual or the group in determining patterns of evolution—then what happens to such cherished driving forces as “the good of the species”? In addition, Dawkins’s insistence on the
