AI Data Centers Could Drive 73-723 TWh of Additional European Energy Demand by 2050, Study Finds
A new arXiv preprint using a spatially explicit optimisation model finds that AI-driven data centre growth could add 73–723 TWh of electricity demand in Europe by 2050 and cause cumulative CO2 overshoots of 67–181 MtCO2 between 2030 and 2050. The research modelled 21 AI growth scenarios and found that after 2030, siting decisions will be driven more by firm power availability and grid flexibility than by clean energy abundance alone. The findings suggest Europe's 2050 net-zero target remains achievable but that near-term emissions risks in the 2030s could undermine the EU's carbon-neutral trajectory without targeted policy intervention.
Researchers from University College London have published a preprint on arXiv modelling the power system implications of hyperscale AI data centre expansion across Europe under 21 distinct growth scenarios. Their spatially explicit optimisation model projects that AI infrastructure could require between 70 GW and 226 GW of additional generation capacity by 2050, depending on growth trajectories and efficiency improvements. In moderate scenarios, data centres would demand roughly 200 additional hours of firm generation annually, raising the levelised cost of electricity by approximately 35 EUR/MWh in major AI hubs. The study identifies a critical intermediate risk window: even if 2050 net-zero goals are technically achievable, cumulative emissions between 2030 and 2050 could overshoot by 67–181 MtCO2, threatening compliance with interim climate commitments. Data centre workload dynamics are shown to significantly influence energy dispatch patterns and system flexibility, while efficiency gains could substantially reduce both peak demand and required capacity additions. The authors conclude that European energy and digital policy must adapt proactively to the pace of AI infrastructure growth to avoid locking in carbon-intensive outcomes during the transition period.

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.
