Not my design 🙂 The only version of these I've seen marketed is the Buerkle Vampire, but it's limited to 5 m depth. I've previously used hand crank Ace/Jack Rabbit peristaltic pumps for deep mid-lake sampling, but unfortunately they've been discontinued. I'm interested in any alternatives!
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
The pre-filled, screwtop Zymo Shield Lysis/Collection Tubes can be convenient and come w or w/o beads (#R1103 'Microbe' has 0.1 & 0.5 mm). FWIW regarding extraction, Zymo said Shield has greater lytic properties than Zymo Lysis Solution, and that Shield deactivates lysozyme but not Proteinase K.
We are hiring! If you're interested in exploring the #biogeography of #prokaryotes using #genomics and #metagenomics, are interested in biology and geographic information systems, and are passionate about #OpenScience, this is for you! New PhD and PostDoc positions in my lab at Aalborg University
Very excited to share our new paper! #microsky #mevosky #microbiomesky 🧬🖥️
This was the second documented polar bear at Summit. There's a NatGeo article about the 2018 incident. EGRIP also had a bear in 2016, and mother/cub tracks nearby in 2024. In emailing with @aederocher.bsky.social about the bear's behavior, he said overland movements are actually pretty common
Aurora Roth and others have drafted a community letter affirming US researcher support for Greenland's self-governance and autonomy. Please consider reading and signing the letter (please use personal email if vulnerable to retaliation!) docs.google.com/forms/d/e/1F...
Has anyone called them histcones? 😀
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
Polar bear sightings far inland on the GrIS are rare. Thankfully (and amazingly) the bear showed little interest while passing through camp and carried on upwind over the horizon. Everyone is safe, wind direction has been consistent, and we're maintaining a 24-hour watch. 3/3
I discovered this just minutes after finishing when I made an unplanned stop at an elevated atmospheric monitoring station.
My head's always on a swivel here, but I have a new appreciation for how difficult it is to spot a bear even in clear conditions. 2/3
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

Looking forward to a week of cross-disciplinary lectures at the #RED24 astrobiology course in Le Teich, France
Happy #InternationalPolarBearDay!
Thrilled to have had the opportunity to present my poster at #PAM2022 @GFZ_Potsdam and to meet so many great people working on really exciting projects
A great day for a ski at the summit of the Greenland ice sheet. 72°35'N, 3210 m
