Had a blast sharing the wonders of #cyanobacteria #phage & #MicrobialCentrism on #MattersMicrobial podcast Also chatted about things like 3D printing, iron, photosynthesis, life in weird places, band names... so much! Thanks again @markowenmartin #MicrobeTV @ClarkUniversity

It's Thursday, so a new episode of #MattersMicrobial! This time, Nathan Ahlgren joins the #QualityQuorum to discuss marine cyanobacteria, oxygen, and the viruses that interact with them. #MicrobeTV @univpugetsound @ASMicrobiology Please share! youtu.be/vAfIUEwv6Xk?si=qYBa…

Great news!!! 🎉 Happy to announce that I'll be joining the University of Prince Edward Island's Biology Department as new Environmental Microbiologist and tenure-track Assistant Professor in May 2025! My students and I will be working on marine phytoplankton and diazotrophs🦠

Excitement is building for the 12th iteration of the Aquatic Virus Workshop to be held at the fantastic Oceanologic Observatory in Banyuls-sur-Mer, France during 5-9 May 2025. We have a great lineup of speakers, and a nascent website: avw12.sciencesconf.org/?lang…

Today our lab finally read the fascinating nitroplast paper. So cool! And the SXT images are amazing. We are wondering what are the pink structure in Fig. 2B and movies? Centrosome or something similar?@kendraturk @Jonathan_Zehr science.org/doi/full/10.1126…

“While this may feel like an ending, it really is just the beginning. It’s the beginning of a great adventure — the rest of your life — one that only you can define and shape,” Gary Labovich ’81, chair of Clark's Board of Trustees, told the Class of 2024. bit.ly/4awp60y

Such an honor to present @VirusesImmunity as an honorary PhD recipient at @ClarkUniversity commencement today. So impressed by her work on so many fronts. Immunology. Long COVID. Vaccine development. Representation in STEM.

Looking for postdoc in #marine #microbiology #virology? We have many avenues for phage-host research: single-cell methods, 100s of #cyano & #phage isolates, bioinf analysis of monthly & weekly time-series. Happy to sponsor application for Simons Postdoc simonsfoundation.org/grant/s…

Boston, population 675k, has 18 city-run pools. Worcester, population 206k, has...one. (via @MASSterList)
Take a swim in summer 2024: Boston pools will be open Last summer, Boston residents couldn't access 10 of 18 city-run public pools due to “facility issues” — issues that officials say will be mostly resolved this summer thanks to about $34M that’s been budgeted over the next few years for pool renovations and repairs, reports the Herald’s Lance Reynolds. — Boston Herald (from Massterlist)

The world’s largest proteins? These mega-molecules turn bacteria into predators

Nature - A candidate for the largest known protein might help killer aquatic bacteria to devour other microbes — but it’s not easy to study the behemoths, or prove they’re even real.

Seeing buzz about PNAS article on the problems of using PCA w/ time series and spatial data, mostly in neurobiology. Wondering how this impacts microbial datasets. @PatSchloss or others want to chime in? pnas.org/doi/10.1073/pnas.23… Phantom oscillations in principal component analysis

My 1st take: don't use PCA in the 1st place on microbial, 16S rRNA data. Use PCoA, nMDS instead (e.g. see this tutorial youtube.com/watch?v=G5Qckqq5… @patschloss) But I'm sure there are microbial community papers out there using PCA... Anyone else want to add? I'm no expert here...

Finally some better bike infrastructure in Worcester! FYI, evidence shows that adding bike lanes in most cases boost business and employment sciencedaily.com/releases/20… and they improve safety for bikers and cars drivers alike sciencedaily.com/releases/20…

Bike lanes provide positive economic impact

Despite longstanding popular belief, bicycle lanes can actually improve business. At worst, the negative impact on sales and employment is minimal, according to a new study. Researchers studied 14...

Excited to show off the lab's first cyanophage plaques from Angell and (Duklida, not pictured), two UG researchers. This is on their first go of it! We have been relying on Marcie Marston for phage isolation in our collaboration, but it was high time to do it our selves.
