Plants and microbes could turn contaminated soil cleanup into resource recovery
A new review proposes treating phytoremediation biomass as a resource for energy, fertilisers, and metals rather than waste.

Browning, not warming, pushes shallow boreal lakes toward bacterial dominance
A controlled pond experiment in northern Sweden shows that increasing dissolved organic carbon, rather than a two-degree warming, reshapes nutrient stoichiometry and shifts microbial production toward heterotrophy in shallow brown waters.

Glowing sugars show how microbes eat the ocean's carbon
A group of chemists, microbiologists, and ecologists has developed a molecular probe (a molecule designed to detect e.g. proteins or DNA inside an organism) that glows when a sugar is broken down. Writing in the journal JACS, the researchers describe how…

Effect of dissolved organic carbon on the transport and attachment behaviors of Cryptosporidium parvum oocysts and carboxylate-modified microspheres advected through temperate humic and tropical volcanic agricultural soil
Transport of Cryptosporidium parvum oocysts and microspheres in two disparate (a clay- and Fe-rich, volcanic and a temperate, humic) agricultural soils were studied in the presence and absence of 100 mg L–1 of sodium dodecyl benzene sulfonate (SDBS), and Suwannee River Humic…

Coccolithophores: Tiny Ocean Algae Could Become Carbon Capture Powerhouses
Italian researchers screened coccolithophore strains under enriched nutrient and carbon conditions, finding that one Chrysotila roscoffensis strain achieved the highest dry weight and CO2 absorption, while Gephyrocapsa huxleyi preferentially boosted calcification—paving the way for algae-based carbon capture and

Mangrove sediments harbour microbes that degrade organic pollutants
Mangrove roots along the estuary of the Mandovi river in Goa have microbes that break down persistent organic pollutants sediments. Credit: Subhra Priyadarshini Along the banks of Goa’s Mandovi estuary, the roots of mangroves shelter aquatic life and trap sediments.

Tiny River Microbes Leave a Measurable Mark on Carbon Dioxide in Taiwan’s Rugged Mountains
A new study of Taiwan's tectonically active Beinan River reveals that planktonic microbial metabolism measurably contributes to carbon dioxide fluxes, with heterotrophic respiration exceeding carbon fixation and microbial communities shifting seasonally between chemosynthetic and photosynthetic dominance.

What Is Aquatic Methane? A Twenty-Year Answer
A while ago, someone asked me if pond methane was real or just a joke (and a business venture). I still don’t know if he meant it seriously. I answered him as if the question was sincere, because it’s a…
