Hi Bluesky microbiology/limnology/hydrology/field folks!
Has anyone used this style of cordless drill peristaltic pump for sample collection or field filtration?
The design checks a lot of our boxes (replaceable tubing, decent suction height, compact batteries), but doesn't seem widely available.

It was wonderful to attend the Polar and Alpine Microbiology Conference in Copenhagen last week and discuss my aerobiology project from Summit Station, Greenland. Thank you @alexanesio.bsky.social for organizing #PAM2026

Happy #AntarcticaDay! Today marks 65 years of the Antarctic Treaty. Here are a few of my favorite photos from my time in the south.

I took biochem in 2001, and for nearly 20 years read amino acid sequences daily… and I never knew Dayhoff named them or even the logic behind things like Q until last Friday (h/t Mike Janech). Also, this is another big Dayhoff moment for me. She was incredible!

I just received this cool piece of Greenlandic history. Rasmussen and Freuchen minted these coins in 1910 as a currency for their Thule Trading Station at Cape York #Arctic #Greenland

Had a wonderful time helping teach a 3-day Environmental Genomics and SeqCode workshop at Shandong University, followed by a weekend of hearing great talks at the Chinese Association of Microbial Ecology meeting in Qingdao, China.

Another polar deployment in the books! A busy and memorable season filled with interesting projects, beautiful fogbows, and a great crew. #Arctic #Greenland #SummitStation

Field work in my final week at Summit Station, #Greenland ended with an unsettling surprise yesterday. Unbeknownst to me, a #polarbear was approaching from directly downwind while I was sampling snow south of station. 1/3
