Preimplantation genetic testing for aneuploidies does not improve live birth rates in couples undergoing intracytoplasmic ...

Almost 80 years ago, in 1944, Avery, MacLeod, and McCarty performed the seminal experiment to determine that DNA was the “transforming principle.” Since that time, the development of methods that ...

New research shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut. Bacteria evolve rapidly in the human ...

Gene transfer agents (GTAs) are unique, phage‐like particles produced by various Alphaproteobacteria that mediate the horizontal transfer of genetic material. Unlike conventional bacteriophages, GTAs ...

Bacteria evolve rapidly in the human gut by sharing genetic elements with each other. Bacteriodales is a prolific order of gut bacteria that trade hundreds of genetic elements. Little is known, ...

Bacteria do not sexually reproduce, but that does not stop them from exchanging genetic information as it evolves and adapts. During conjugal transfer, a bacterium can connect to another bacterium to ...

Researchers now have a better understanding of the mechanism underlying how certain bacteria can transfer genetic material across taxonomic kingdoms, including to fungi and protists. Their work could ...
