We got power back as I was about to go on a dry ice run! Raised to -65 °C in 3 hours.

My building just lost power. Our -80C are not on backup (not my choice). Anyone know how long a freezer can maintain temperature if it isn't opened?

We have one in my laboratory. It's a recent acquisition, so we're still figuring it out, but happy to help.

Revitalizing actinobacteria research: an urgent response to the antimicrobial resistance crisis - Natural Products and Bioprospecting Abstract The crisis of antimicrobial resistance (AMR) is escalating while the antibiotic pipeline remains stagnant. Our bibliometric analysis of eight decades of literature reveals a critical imbalanc...

Research into filamentous actinomycetes, the antibiotic producers, is in steep decline. Loads of natural products chemistry research worldwide but not much aimed at understanding their biology and ecology. The latter is key to unlocking their specialised metabolism

Agreed. Printing PP is a pain, but so worth it for lab stuff. There are also services you can upload an STL to and get a print that might be easier for one off pieces.

Would you mind sharing a reference or sequence? Would love to look into this more.

Colleague I've talked to says they specifically have the problem using sacB in plasmids with R6K origins. Anyone else experience this?

Does anyone have experience with counter-selectable markers for Gram-negative bacteria besides sacB? It's been working poorly in our hands.

Rothia similimucilaginosa sp. nov., isolated from the human nasal cavity Four strains of a Gram-stain-positive, coccoid, catalase-positive, non-motile bacterium were recovered from nasal lavage samples collected from children in Wisconsin during the Spring of 2008. These s...

My lab has published our first paper! We previously showed that Rothia are associated with healthy nasal microbiomes and inhibit the pathobiont Moraxella catarrhalis. We now describe the novel species Rothia similimucilaginosa. Check it out here: www.microbiologyresearch.org/content/jour...

I’m excited to share the first paper from my lab that was led largely by undergraduate students at University of Wisconsin and Washington College! #secmet #natprod

Semester ended with two manuscripts accepted after over a year each in review! Happy Holidays all!

Ooof. No thank you!

Yeah. Standard LB. This is looking possible likely based on some preliminary tests we've done.

Thanks! Yeah. Agreed. Both are worth testing. Might be time to dump the competent cells.

We have been dealing with high background using erythromycin selection for multiple E. coli strains in my lab. We've tried multiple vendors and lots, but the problem persists. Has anyone else had this problem before? Any ideas?

#NewPI life

In biology, I keep thinking of the bacterial strains, yeast strains, plasmids, mouse lines, worm mutants etc etc etc that will be lost to science FOREVER because the freezers and animal facilities won't be maintained

Generations of work will be lost in essentially an instant

Functional Metagenomic Selections for Phage Defense

My lab’s first preprint!

We used functional metagenomics to identify phage defenses in human and soil microbiomes. We scaled these selections while maintaining accuracy, enabling us to examine 9 habitats for defense elements against 7 phages.

NSF downsizes summer research program for undergraduates Many participants are from groups underrepresented in science

"downsizes" is a weak way of saying "forced to cancel dozens of programs, which jeopardizes future STEM careers of talented undergrads" @science.org www.science.org/content/arti...

Some of my first year grad students in my class are asking for books to read that will get them thinking about what questions to ask and how to know what they should ask. I have a couple of recs but wondering if anyone can help. What inspired you??
