Metabolic Processes Preserved as Biosignatures in Iron-Oxidizing Microorganisms: Implications for Biosignature Detection on Mars [PDF]
Iron-oxidizing bacteria occupy a distinct environmental niche. These chemolithoautotrophic organisms require very little oxygen (when neutrophilic) or outcompete oxygen for access to Fe(II) (when acidophilic).

Adaptive Significance of Nickel Hyperaccumulation by Plants
Ecological Research, Volume 41, Issue 2, March 2026.Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...

Environmental Microbiology, Volume 28, Issue 3, March 2026.Using a combination of deletion mutants' construction, phenotyping of these mutants and complementary biochemical analyses, we established that the environmental Shewanella sp. ANA‐3 is using both the tetrathionate reductase Ttr and the polysulfide reductase Psr to respire tetrathionate.

Design, Synthesis, and Evaluation of Bis‐Chalcones and Bis‐Flavones as Selective COX‐2 Inhibitors
Chemical Biology &Drug Design, Volume 107, Issue 3, March 2026.Novel bis‐chalcones were successfully synthesized and demonstrated COX‐2 selective inhibition and the ability to inhibit PGE2 production in whole human blood. Notably, a monomeric chalcone with a similar substitution pattern exhibited even greater activity, providing valuable insights to guide the future design and optimization of flavonoid‐based COX‐2

Epidemiology of progressive intellectual and neurological deterioration in UK children
Developmental Medicine &Child Neurology, Volume 68, Issue 3, Page 418-428, March 2026.This study of PIND in UK children was carried out via the British Paediatric Surveillance Unit from 1997 to 2024. It identified six cases of vCJD. 2367 children had other diagnoses explain their deterioration. There were 259 other diseases in the diagnosed group.

Anaemic Streams: Iron and Essential Trace Metals Frequently Limit Primary Producer Biomass
Ecology Letters, Volume 29, Issue 3, March 2026.Nutrient enrichment experiments in 41 streams across the eastern United States demonstrate that trace metals can limit the growth of primary producers. Trace metals are frequently co‐limiting with macronutrients and the availability of N and P in streams and watersheds are predictive of Fe and Zn limitation status.

The FEBS Journal, Volume 293, Issue 6, Page 1754-1770, March 2026.The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

The FEBS Journal, Volume 293, Issue 6, Page 1624-1642, March 2026.Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

New Phytologist, Volume 249, Issue 5, Page 2452-2466, March 2026.Summary Plants orchestrate their developmental processes and responses to environmental stimuli through a sophisticated network of small signaling molecules, termed phytohormones. Among these, auxins are recognized for their role in promoting plant growth.
