This week's breakfast journal club was led by @kajsaroslund.bsky.social, where the relevant topic of fairness on peer review was discussed.

The lunch time meeting before the DNRF annual visit was busy, with an introduction from Jonathan Donhauser on his project on developing a #model for #microbial #VOC emissions, followed by practise talks by @nasmillelarkemejia.bsky.social and Ida Friis, which were a success on the day of the visit!

This week we had the pleasure of hosting the @dg.dk annual visit to @voltcenter.bsky.social. As always, it was time to reflect on the success of the past year, and what a joy it was to relive all the highlights through @riikkarinnan.bsky.social's presentation!

A formal self-introduction for a less formal audience. After being with us for a while, we finally got to "formally" hear from visiting postdoc Junyu Dong about his previous work in China, and a bit of his project with #VOCs here at @voltcenter.bsky.social 😄

New publication on Biology and Fertility of Soils led by Dr. Zhiyang Zhang. Title: Herbivore dung inputs mainly drive copiotrophic bacterial contributions to soil nutrient pool turnover in alpine grasslands doi.org/10.1007/s003...

Last weekend, VOLT joined the #Fungi Festival🍄🍄‍🟫. Visitors got to hear a talk on hidden #fungaldiversity in #caves, and explored a collaborative booth. Here they could peek at fungal cultures under a microscope🔬, watch a short film highlighting the research, and learn about cave fungi and #VOCs.

Looking for something fun and interesting to do in the #weekend in #copenhagen? Come to the #fungi #festival and listen to @voltcenter.bsky.social's @kajsaroslund.bsky.social's talk together with @kbodawatta.bsky.social on cave microbes and explore unique-looking fungi @ our stall! shorturl.at/22mEG

We just received a "postcard" from #Barcelona! @voltcenter.bsky.social's postdoc Cecilia Costas Selas and PhD student Eve Galen are attending the #SAME18 #aquatic #microbes #conference. Enjoy the sunshine and the talks, posters and discussions!

Pitched at #FallingWallsLab last week 🌍✨ Didn’t win, but left inspired, with new connections, and excited to keep sharing the hidden world of microbes. Next step: #ArcticBear_game 🎲 — a board game to show how microbes help protect our planet. #uArctic_project

📸 Last chance! The deadline to enter the 2025 Photo Competition is TOMORROW! 👉https://dg.dk/en/dnrf-photo-competition-2025/

Really enjoyed the annual @voltcenter.bsky.social retreat with great colleagues - two days of science, creativity, and connection. Great energy to carry into the rest of the academic year!

Every year on week 37 @voltcenter.bsky.social goes away for two days of science, fun, inspiration and team building. Here are some of the many highlights in thread:

Sometimes science is field work, sometimes it is lab work, computer work, discussions, presentations... and sometimes it is executing plan B and driving a highly sensitive and sophisticated scientific instrument across four countries and over 1500 kilometers! www.ionicon.com/blog/2025/a-...

Our summer fieldwork has started to take shape in the lab! ⛰️🔬 Today’s lunch meeting featured talks on ongoing projects and experiments surrounding #moss and #isoprene, and discussions on the next steps ahead.

It apPEARs more exPEARiments are needed. The PEARameters are imPEARcise, and it is imPEARative to PEARform PEAR-wise comPEARisons.

❗Job altert!❗ @voltcenter.bsky.social is #hiring a #LabManager /Lab specialist. Are you familiar with PTR-TOF-MS and GC-MS? You'll coordinate lab&field activities, QC&calibration, solve problems, assist with tech installations, and provide tech support to researchers employment.ku.dk/all-vacancie...

📣New paper📣 We measured #VOC & #CO2 fluxes from 3 ponds in a peatland forest using floating chambers. Understanding of freshwater ecosystems as VOC sources is poor, so this work led by Y. Qin, published in #ASLO_LO provides important new data. doi.org/10.1002/lno.... @dg.dk @voltcenter.bsky.social

Net #emission of #atmospheric volatile organic compounds ( #VOCs) from #ponds in a #peatland #forest by @voltcenter.bsky.social's former MSc student Yinghuan Qin is out now! doi.org/10.1002/lno....

Monday mornings are for breakfast journal clubs. 😋🤓 At @voltcenter.bsky.social we started the week with a discussion on #microbial #ecological strategies, led by postdoc Jonathan Donhauser.

#DHLrace day! The @voltcenter.bsky.social team is ready and in high spirits. Bring on those 25k per team! 🏃‍♀️🏃💨💪

Clean-up day at BIO!🧹 VOLT members came together to organize and clean our shared spaces 💻🔬🧪. With teamwork, enthusiasm (and cake!), we now have refreshed workspaces to support our projects.

Today we welcomed Professor Sándor Gonda from the University of Debrecen, for a guest talk on plant-microbe interactions at the plant metabolome level in horseradish. He shared interesting insights on a species that most of us had never studied before! 🌱

We are now (mostly) all done with holiday and field work, and we kick off being back in the office with a breakfast journal club hosted by postdoc Mehrshad Foroughan on new insights in #climate #science. How is your lab coming back into the swing of things?

Another late night in the lab… and between sampling points I made this inspired by my #Sphagnum #moss floating in my vials #uArctic_project #scienceart #midnightart @voltcenter.bsky.social

This is my first time using a #PTR-TOF to track isoprene consumption over time… huge thanks to @voltcenter.bsky.social! 🤓 In the previous image, the black peaks represent #12C isoprene and the red ones show #13C isoprene. Concentrations are around 5–10 ppmv. 🏔️ spectra using 95% labelled 13C-isoprene

Meet Mehrshad, a PostDoc at VOLT researching #VOC exchanges between the #ocean and the #atmosphere 🌊☁️. Using high-frequency measurements from a remote field site, he focuses on understanding how various physical and biological factors affect these exchanges.
