From Electroculture to Plasma Agriculture: Historical Evolution and Modern Applications
A new review article published in Compte-Rendus Mécanique traces the history of using electricity in agriculture from Abbé Bertholon's 18th-century experiments to contemporary cold-plasma technologies. The paper argues that Bertholon's intuition of a 'vivifying electricity' — channeled through devices like the electro-végétomètre — foreshadowed modern plasma agriculture despite lacking rigorous methodology. The review matters because it frames plasma agriculture, which encompasses seed treatment, plant growth stimulation, and food decontamination, as a scientifically grounded evolution of a centuries-old idea with implications for sustainable farming.
A review paper by Thierry Dufour, published in Compte-Rendus Mécanique de l'Académie des Sciences (Volume 354, 2026), charts the three-century arc of electricity's role in agriculture, beginning with Enlightenment-era observations and culminating in 21st-century cold-plasma science. The paper highlights Abbé Bertholon's pioneering 18th-century work, in which he attempted to harness atmospheric electricity to stimulate crop growth using an instrument called the electro-végétomètre, acknowledging that these experiments lacked quantitative dosimetry or rigorous controls. The review then traces how advances in galvanism, electrochemistry, and gaseous discharge physics during the 19th and 20th centuries collectively built the scientific foundation for modern plasma technologies. In the contemporary era, plasma agriculture is described as an interdisciplinary field combining electrical, chemical, radiative, thermal, and fluid-mechanical effects, with applications ranging from seed priming and soil treatment to the decontamination of agri-food products. The authors ultimately argue that plasma agriculture can transform what was once an intuitive Enlightenment concept into a reproducible experimental framework capable of contributing to sustainable agriculture and food safety.
What's missing
The review is a historical and conceptual synthesis rather than an original experimental study, so it does not report new empirical data on plasma agriculture efficacy. Key open questions include the scalability and cost-effectiveness of cold-plasma technologies for real-world agricultural deployment, long-term ecological effects of plasma-treated soil and water, and the degree of regulatory acceptance across different jurisdictions.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
