Horizontal Gene Transfer Happens More Often Than Anyone Thought
Christie Wilcox, PhD | Jul 5, 2022 | 10+ min read
DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

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.

Genetic Parasites and a Whole Lot More
Barry Palevitz | Oct 15, 2000 | 10+ min read
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
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
Opinion: Constrain Speculation to Protect the Integrity of Science
Mike Klymkowsky | Jun 18, 2018 | 4 min read
What we can know about biology before the last universal common ancestor is limited—and we should be circumspect in filling in the gaps.

Some Cancers Become Contagious
Katarina Zimmer | Apr 1, 2019 | 10+ min read
So far, six animal species are known to carry transmissible, “parasitic” forms of cancer, but researchers are still mystified as to how cancer can become infectious.
