Horizontal Gene Transfer Happens More Often Than Anyone Thought
Christie Wilcox | Jul 5, 2022
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 | Mar 3, 2022
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.

Alu Leap May Explain Why Apes Don’t Have Tails
Annie Melchor | Sep 23, 2021
A transposable element that jumped into the TBXT gene, which is linked to tail morphology, appears to be to blame for our missing appendage.
Male Flies’ Y Chromosome May Contribute to Earlier Deaths
Jef Akst | Jul 13, 2020
As male Drosophila grow old, selfish genetic elements that are abundant on the Y chromosome become more active, which appears to reduce longevity.
