Pensar con y a partir del operón

Revista Colombiana de Filosofía de la Ciencia
Este artículo sostiene que el operón lac propuesto por François Jacob y Jacques Monod en 1961 superó los campos de la cinética enzimática y la genética bacteriana en los que se estableció originalmente porque impulsó una metodología de análisis, el ...

Roles of Alp and Prt Regulons in the Response of Pseudomonas aeruginosa to UV‐C Light

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Our results show that LexA‐regulated genes are the first to be induced after DNA damage, while autolysis functions controlled by the Alp system are the last. Death by UV is mediated primarily by Alp or Prt systems, depending on the Pseudomonas aeruginosa subline. ABSTRACT UV light is a well‐studied environmental DNA damaging agent.

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging

Aging Cell, Volume 25, Issue 2, February 2026.
This study analyzed gut microbiota in older adults with and without Frailty Syndrome by 16S rRNA gene sequencing and metagenomics. Frailty was associated with altered microbial composition, metabolic functions, and increased antimicrobial resistance, whereas non‐frail individuals showed healthier profiles.

Flavin Biosynthesis Enhances Extracellular Electron Transfer in Bioengineered Escherichia coli

Advanced Science, Volume 13, Issue 2, 9 January 2026.
Microbial electronics are promising for energy, sensing, environmental, and synthesis applications. E. coli are engineered with extracellular electron transfer (EET) pathways from a microbe that naturally produces current to enable bioelectronics based on E. coli.
