Ancient metagenomics reveals subglacial microbiomes driven by oxygen availability www.biorxiv.org/content/10.6... #jcampubs

The Ice is Alive: Uncovering the Vanishing World of Glacial Microbes Glaciers are flush with microbial life. But, as climate change speeds glacial melting, scientists rush to establish microbial biobanks to preserve them.

Lovely to feature alongside the brilliant Birgit Sattler & Tom Battin in this story about life in Earth's dying ice.

MAG placement in the phylogenetic tree. Different colours indicate the phylum-level classifications of the clusters. MAG taxonomic annotation at the class level is shown in bold, with the number of associated MAGs indicated in brackets. The taxonomic classification at the family level and the number of MAGs ascribed to each family (in brackets) is reported below the corresponding class. *Not phylum level.

In 1916 the BMJ published an article about the work done by James Shearer, an American physician working in the British Army as a sergeant (because he had no British qualification). He had described a "delineator" which was better than x rays for portraying gunshot wounds. This caused a sensation and a lot of interest — but on investigation the work was found to have been invented. The BMJ published a retraction, but Shearer was tried by court martial and sentenced to death by firing squad.

Next time an institution tells you how seriously it takes research misconduct, ask them if it's *this* seriously. www.bmj.com/content/297/...

Far too optimistic take on this. Be realistic - being a Nobel-level scientist is the best chance of having three whole weeks away from work email, and this sets a precedent that even then, someone will not heed your tripnote.

Just signed up to peer review an application for one of the largest science funders in the world.

Asked to confirm I was at least 13 years old. Might explain a lot about the grant review process if it's secretly dominated by teenagers.

Sad views from southern #Svalbard 30.8.25 - melt has reached high up the mountains. From Hornsund to Amundsenisen barely any snow left… how should glaciers build mass like this? Svalbard is heating fast. Only steep mountain walls seem to help accumulate a bit and catch blown snow 📸from✈️

Ah, but you do so much more and get to work with amazing gadgetry that pings data back from inside ice sheets and stuff.
