Today npj Antimicrobials and Resistance has received its first impact factor. Now, we all know that impact factors don't tell the whole story and aren't a standalone mark of quality. That said, we are hugely proud of the success of the journal so far....

Excited to share the first paper from the Kowalski Lab out in mSphere! My superstar technician Sylvia helped write this review while we were getting the lab set up. We discuss how the skin microbiota generates bioactive lipids in the skin environment. Take a look: journals.asm.org/doi/10.1128/...

Skin serves the essential function of protecting internal tissues. Through multiple layers of tightly packed cells held together by proteins and lipids, stabilizing connective tissue, and a deep layer...

What if bacteria were using wax esters to shape skin microbiomes? Staphylococcal lipases convert skin antimicrobial fatty acids into harmless wax esters. This publication is the very first first-author paper for my first PhD student, my first time acting as last author, and our first ISME paper.

Extracellular wax ester biosynthesis by staphylococcal lipases detoxifies skin fatty acids and shapes interspecies competition

Abstract. To maintain its barrier function, human skin requires lipids, including cholesterol, ceramides, free fatty acids, and wax esters. In contrast to

What would happen if Darwin, Russell Wallace and Koch walked into a bar? We present our new way to study mycobacteria, employing a macroevolution framework (species not strains). Possibilities are endless!! Thanks to Fernanda Subtil for pushing this. elifesciences.org/articles/101...

A macroevolution-inspired approach to reveal novel antibiotic resistance mechanisms

Using macroevolution, species not strains, uncovered important diversity in how mycobacteria respond to and resist antibiotics, revealing novel resistance determinants.

We found maternal helminth infection can promote antiviral immunity in offspring 🤱🪱 www.cell.com/cell-host-mi... Don’t worry, we are not suggesting we reinfect everyone with worms! Instead, we identified a microbiota-derived metabolite, Indole-3-propionic acid, that enhances antiviral immunity!

Maternal helminths rewire the microbiota to promote offspring antiviral immunity

Fernandes et al. show that maternal helminths, long-standing mammalian partners, confer antiviral immunity to offspring via the microbiota-derived metabolite indole-3-propionic acid (IPA). This work r...

This is a long shot, but is anyone willing and able to review a micropublication (i.e., short and sweet) about how senescent-associated β-galactosidase accumulation influences the lifespan of a particular species (a fish, if it matters)? We can't find a reviewer and we've tried so hard. 🧪
