@theDANlab Blurry photo at least means we had a good time!

#plant people! Help! Does anyone know why my #cacao plant used to make solid dark green leaves, but now it's making pale leaves with only green in the veins? Is this #chlorosis (& what do I do)??

Completely dried out B. subtilis biofilm - look at all those folds! @theDANlab #biofilm #sciart #microbiology

I'm definitely biased, but don't we all wanna... Save the 🌍?!

Paper is out! Some nifty stuff happening with the relaxosome in the gonococcal T4SS: https://t.co/7sDMc16LVK

Thrilled to share that my PhD work @UWMadisonMDTP on the influence of environmental factors on the #Ngonorrhoeae #T4SS is published at I&I! Couldn't ask for a greater group with @Sacculus097 @AbigailCShockey @Pepperell_Lab and others @UWMadisonMMI! https://t.co/qm6OoKwM4b

It's #STDWeek with the CDC @CDCSTD! Can you imagine if we embraced #STI testing and communication the same way we've been managing our COVID testing?!

[Melanie Callaghan @MelsCells]

My lab started a Youtube channel! We're starting by demo-ing our protocols for extracting metabolites from bacteria and then concentrating those samples - we use these to get a snapshot of the metabolite profile happening in cells!

A type 11 secretion system! ELEVEN!!

[Melanie Callaghan @MelsCells]

@DearBacteria Sorry yes I should have included that, M9 with 4g/L glucose, I want them to ferment. I thought they might just be glucose limited, but increasing [glucose] did not increase my terminal ODs

[Melanie Callaghan @MelsCells]

#Sciencetwitter! Can someone talk to me about anaerobic E. coli growth?? I've got cultures reaching low terminal OD and I'm on the hunt for ideas

Our pre-print is out! The bacterial agent of #gonorrhea upregulates expression of its #DNA secreting #T4SS in conditions of infection - active urethral infections, biofilms, and metal conditions mimicking the host cell phagosome! @Sacculus097 @Pepperell_Lab @UWMadisonMMI

9am and my coworker is already trying to take a snack break

[Melanie Callaghan @MelsCells]

So what does it mean when @UWMadison ghosts you on your covid test result??
