Last month's total #Arctic sea ice volume averaged the 3rd lowest on record for the month of August. This was about 72% below 1979 levels and 54% below the 1979-2024 August average. More at zacklabe.com/arctic-sea-i.... Data from PIOMAS. 🥼❄️🌊

Did you know tiny algae can "skate" within Arctic sea ice? ⛸️ Our new study in @pnas.org reveals the secret life of ice diatoms: they are actively gliding to navigate the ice! This adds a new dimension to the sea ice ecosystem, revealing an active, dynamic ecological niche. @prakashlab.bsky.social

A must-read for policy makers!

👋Hey ice fans! We’re looking for a post-doctoral fellow to join our glaciology team! 👇 Call: candidate.hr-manager.net/ApplicationI... Deadline: 30 Sep 2025

New season. New styles. Buy more. Buy cheap. Move on. Throw away. The impact of ‘fast fashion’ is polluting land, rivers, seas and the air we breathe. Consider the environmental footprint before purchasing. By making mindful choices, we can help #BeatPollution: www.unep.org/beatpollution/

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

New palaeo-PhD opportunity! Will you be the one to figure out the anatomy and function of fossil jawless fish? Come join the team! Application Deadline August 22nd, funding for UK student only (sorry) www.findaphd.com/phds/project...

We proudly present the brand new GEUS sedimentary ancient DNA lab! We just finished setting up the lab after days of scrubbing, sweat, and teamwork! Huge shoutout to Clara S. Adsersen for bravely diving in and making it all happen — couldn’t have done it without you! 🧬💪✨ #LabLife #aDNA

New paper alert! We have just published an open acces paper in Climate of the Past, that has dated lacustrine permafrost sediments from northeast Siberia to the last interglacial using luminescence dating. doi.org/10.5194/cp-2...

Detailed investigations of permafrost deposits in Arctic Siberia suggest a much warmer Last Interglacial than today for that region: new Study out by Schirrmeister and a larger international team of colleagues: doi.org/10.5194/cp-2...

As only Julian Aguon can tell, a story as beautifully told as it is devastating and inspiring. About how “Vanuatu, a South Pacific island nation on the frontlines of the climate crisis, is fighting for climate justice at the world’s highest court.” www.rollingstone.com/politics/pol...

Today, our postdoc Jérémy Courtin presented the first results of our #DFF project FunCap at the #sedaDNA Society Meeting. Great lightning talk on how hybridization capture can be used to uncover how Arctic marine biodiversity responded to past climate changes. 🦠🐙🧪🔬🧬

Whales, Greenland, and some really old mud. My first PhD chapter now published in @natcomms.nature.com reveals 12,000 years of marine mammal history around Northern Greenland through DNA hidden in marine mud. Check it out: rdcu.be/emdYS #sedaDNA #Greenland #Arctic #whales #seals

[PODCAST] A US biotech company made headlines last month revealing photos of genetically modified “dire wolves,” a species that hasn’t existed for more than 10,000 years. This hasn’t stopped some observers from asserting to the public that “de-extinction” is real. But it’s not, says our guest.

This would be a great opportunity for a foundation/university to step in, open source these products, and maybe even make them better and more useful.

We need to work towards standards with respect to DNA #metabarcoding. Not strict ones. Minimum standards plus QA/QC. We just must make sure that we measure what’s around in a comparable way. Often but not always the case. Interested to join a special session?
