Several years of work with several great collaborators, that combined computational biology, molecular microbiology, biochemistry, structural biology and mycology assay culminated in today's publication on discovery of novel bacterial toxins:

Systematic discovery of antibacterial and antifungal bacterial toxins - Nature Microbiology
Genome sequence mining and computational analyses lead to the discovery and functional characterization of conserved bacterial toxins with activity against bacteria and fungi.

Are you looking for a reason for optimism in 2026?

Once a year or so flashfloods carry rain water to the Judea desert, below sea level. If you're lucky enough, as my kids and I were yesterday, you can watch them 'live streaming'.

Pretty cool!
Interkingdom sensing of fungal tyrosol promotes Yersinia pseudotuberculosis antifungal T6SS activity in the murine gut. The effector acts as a chitinase.
Tyrosol acts as a quorum sensing molecule in species like Candida albicans,

Interkingdom sensing of fungal tyrosol promotes bacterial antifungal T6SS activity in the murine gut - Nature Microbiology
Yersinia pseudotuberculosis senses fungal tyrosol signalling through EnvZ–OmpR which triggers T6SS activation and antifungal effector release to reduce fungal competitors in the mouse gut.

Me to the students in the seminar course:
divide a multi-panel figures to several simple slides (a paper and a talk are not the same), use only large fonts also for people in the back (axes included), clear titles.

Me in conferences: I wish I could recruit professors to attend my undergrad seminar

@soreklab.bsky.social Sorek lab does it again! Such a cool signal to specifically detect the event of genome degradation by a phage
Bacteria sense virus-induced genome degradation via methylated mononucleotides
Phages often degrade the genome of their bacterial host to individual nucleotides and use these nucleotides to build their own genome. In this study, we describe a bacterial defense system that direct...

@sheilaroitman.bsky.social from Detlef Weigel's lab @plantevolution.bsky.social presents a cool and innovative talk on the uncharacterized members of the plant microbiome: phages!!
So many bacterial 16S studies but very few people study the plant phagome

Thanks Akos.
It would be great if other labs will follow up on this to decipher why plant microbiota are depleted from mobile genetic elements and defense aystem.
Do plants protect the microbes from MGEs?
OK, that was not finishing yet, Asaf now switches to insect connected microbes and the yellow pigmented Chryseobacterium isolate and in vivo virulence of the strain (in hemolymph)

= new model to study (insect) virulence of plant microbiota

@finkel-lab.bsky.social and I went on a beautiful morning run in hilly Antequera (south Spain).

Too much cerveza and jamon iberico made us heavy.

We are interested in proteins, we do some AI, and I still could not understand what this paper is about based on the abstract.
