Some Viruses Use an Alternative Genetic Alphabet
Abby Olena | Apr 29, 2021
In a trio of studies, researchers follow up on a 40-year-old finding that certain bacteriophages replace adenine with so-called diaminopurine, perhaps to avoid host degradation.
Q&A: Natural History Museums’ Role in Pandemic Surveillance
Max Kozlov | Jan 21, 2021

Giant Viruses Can Integrate into the Genomes of Their Hosts
Amanda Heidt | Nov 19, 2020
Rather than introducing small chunks of DNA as other viruses do, some giant viruses can contribute more than 1 million base pairs to a host’s genome, broadening the ways in which viruses may shape eukaryote evolution.
Cells’ Response to SARS-CoV-2 Different from Flu, RSV
Abby Olena | Mar 31, 2020
The host transcriptional signature elicited by the coronavirus appears to be less robust and lacks the induction of key antiviral genes.

Animal Mind Control
Jef Akst | Jan 1, 2012
Examples of parasites that manipulate the behavior of their hosts are not hard to come by, but scientists have only recently begun to understand how they induce such dramatic changes.
