To this end, we propose and solve a simple phenomenological model of CRISPR-based adaptive immunity in microbes. We show that in coexisting phage and bacteria populations, immune diversity in both ...

The authors provide compelling evidence connecting proteostasis with gene duplication during experimental evolution in a model system. This paper is likely to be of interest to researchers studying ...

Bacterial evolution is the process of heritable change in populations of bacteria over multiple generations. It occurs through mechanisms including natural selection and genetic drift, and can ...

Damaged but Not Defeated: Bacteria Use Nano-Spearguns to Retaliate Against Attacks Mar. 5, 2025 — Some bacteria deploy tiny spearguns to retaliate against rival attacks. Researchers mimicked ...

Bacterial 'jumping genes' can target and control chromosome ends Date: March 6, 2025 Source: Cornell University Summary: Transposons, or 'jumping genes' -- DNA segments that can move from one part ...

A recent study by Chinese scientists has revealed the intricate molecular machinery driving energy exchange within ...

Bacteria navigate tradeoffs between phage resistance and interbacterial competition. This study reveals that while LPS ...

Conjugation is a form of horizontal gene transfer that allows the exchange of genetic material between two organisms or cells ...

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance. Cornell ...

Point mutations are often thought of as the raw material of evolution; these small changes ... us insights into the evolutionary pressures on bacterial pathogens.

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University ...
