Next-generation sequencing has identified scores of new microorganisms, but getting even abundant bacterial species to grow in the lab has proven challenging.

SARS-CoV-2 infection triggers structural changes in the host cell’s DNA, which provide a molecular explanation for long COVID, a new study suggests. 

Scientists continue to ring alarm bells about the risks associated with the continued misuse of antimicrobials and advocate for innovative treatments, improved surveillance, and greater public health education.

Everyone knows that the first genome sequencing projects took years of work and represent the combined product of tens of thousands of individual fragments.

The scientific community said goodbye to Sydney Brenner, Paul Greengard, Patricia Bath, and a number of other leading researchers this year.

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.

A device dubbed the “mother machine” enables real-time observation of mutagenesis in single bacterial cells.  

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

Viruses, Diseases Author: Karen Young Kreeger Sidebar: Professional Resources for Viral Disease Researchers In the mid- to late 1980s, numerous correlations were discovered between viruses and various types of cancers. For example, Epstein-Barr virus was associated with nasopharyngeal carcinoma and B-cell lymphoma, hepatitis B virus with liver cancer, and human papillomavirus with cervical cancer. Now, a decade later, basic and clinical scientists are finding out that viruses may also play a r

Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--
