Four time points out of 6 completed in our first experiment (chalk stream) and it's all going well. Next stop is deployment of the biofilm frames in our clay stream to develop biofilms for experiment 2 in 3 weeks time. Great help from @sydneyenns.bsky.social from our @ukri.org QUANTUM team. 🧪
PI setting up for 48 h sampling at our chalk stream site. Dr Charlotte Briddon transferring our biofilm frames to our clay stream site to start incubation. Each frame holds 45 glass slides, and we need c. 450 for each experiment. @jameslmcdonald.bsky.social from ERC REFRESH and @sydneyenns.bsky.social from NERC QUANTUM deploying the frames in a sunny part of the stream.

Fun with Dicty and predation-resistant biofilms and better curriculum materials with @teralevin.bsky.social !
The EvolvingSTEM program partners with teachers to develop authentic research experiments that improve students’ understanding of evolution and microbiology and connects these topics to issues in medicine. In one of these experiments, students investigate how biofilm adaptations protect Pseudomonas fluorescens from being consumed by a common soil predator. This experiment allows students to study an important mechanism bacteria use to protect themselves from predation in natural environments and models how bacteria can evade phagocytic immune cells such as macrophages. The Catalyst Award will support a partnership between members of the Cooper, Levin, and Quigley labs. This collaboration will allow us to (1) improve curricular materials by making stronger connections between the students’ classroom experiments and their biomedical relevance, (2) implement the updated materials in Pittsburgh area middle and high schools, and (3) assess their impact on student occupational identity development using a mixed-methods design that collects quantitative and qualitative data.

And that's the final @erc.europa.eu @ercrefresh.bsky.social stream isotope experiment of our 2025 field season complete. With many thanks to @bristoluni.bsky.social PhD students Matt McCormack and Boyi Li for their help with eDNA sampling and completing site decommissioning before the rain arrived 🧪

Matt and Boyi transferring heated mesocosms to the bank for eDNA and eRNA extraction, led by Martin Genner Leave no trace! Site returned to its original state after decommissioning. With many thanks to Bannau Brycheiniog National Park Authority for permission to work on the land.

Follow the team @ercrefresh.bsky.social as we investigate controls on rates & pathways of DOM uptake into stream foodwebs. This week we ran the first of 3 experiments exploring if environmental character, warming or velocity affect uptake this week. Chalk stream first, then clay stream, then peat! 🧪
Meet the team! Drs Charlotte Briddon and @jameslmcdonald.bsky.social, working on setting up the motors to drive the paddles in our warming (bubble wrap jackets, elevated higher in the water column) and warming plus high (double the rpm) flow velocity experiment. Further along, Dr @acastrocastellon.bsky.social from our @ukri.org NERC QUANTUM programme is setting up the jars for our ambient temperature with stirring experiment in this classic chalk stream. The catchment comprises calcium carbonate rich chalk, flows to the river are dominated by groundwater and deeper throughflow, and the stream ecosystem supports Ranunculus spp. (water crowfoot), Callitriche spp. (starwort) and Rorippa nasturtium-aquaticum (watercress) along with a native brown trout population. How will biotic response rates to isotope dosing of 13C15N labelled compounds in this alkaline, and gin-clear stream contrast with those in a more turbid clay stream (experiment 2) and dystrophic peatland stream (experiment 3). We look forward to finding out! Each jar contains biofilms cultivated in the stream prior to each experiment, and mosses (Fontinalis antipyretica) which are ubiquitous in UK rivers and streams. Their lack of rooting structure makes them ideal for these isotope dosing experiments. Later on in the programme we will introduce benthic chambers and endemic higher plants, but these 6L mesocosms are too small to accommodate them. The final set up, the evening before the first sampling at time point 0. We then sample at 1.5 h, 6 h, 24 h, 48 h, 96 h (at which point we introduce snails to graze off the biofilms and bryophytes) and 192 h. So many moving parts to go wrong, and each jar 9x 3 replicates) receives a different dual-labelled DOM compound at 1% enrichment of N over background. These are not enrichment nor depletion experiments (those come later in this 5 year ERC Advanced Grant programme, awarded to @penny.johnes.bsky.social ) and funded via @ukri.org under the Horizon Guarantee. The PI @penny.johnes.bsky.social having rather too good a time. Science is always fun, but also often quite challenging when we are conducting experiments under environmental conditions. It's always a relief when the kit is in and working and the design is correct!

Shading experiment shows that diatom-based periphyton communities in streams have greater nutritional quality with a higher proportion of PUFAs. Thus, shading associated with riparian plantings may enhance high-quality carbon transfer to consumers in higher trophic levels through bottom-up effects
Nutritional Quality of Basal Resource in Stream Food Webs Increased with Light Reduction—Implications for Riparian Revegetation - Microbial Ecology
Biofilms are considered a basal resource with high nutritional quality in stream food webs, as periphytic algae are abundant of polyunsaturated fatty acids (PUFAs). PUFAs are essential for growth and ...

This plastic disappears in the deep sea—and microbes make it happen
Researchers have demonstrated a new eco-friendly plastic that decomposes in deep ocean conditions. In a deep-sea experiment, the microbially synthesized poly(d-lactate-co-3-hydroxybutyrate) (LAHB) biodegraded, while conventional plastics such as a representative bio-based polylactide (PLA) persisted. Submerged 855 meters (~2,800 feet) underwater, LAHB films lost over 80% of their m*** after 13 months as microbial biofilms actively broke down the material. This real-world test establishes LAHB as a safer biodegradable plastic, supporting global efforts to reduce marine plastic waste. Despite the growing popularity of bio-based plastics, plastic pollution remains one of the world's most pressing environmental issues.
