Buenos dias!! Greetings from Spain.

Today we can highlight a very interesting article of gut–brain modulation of a monkey model of human depression, MELODY a new trial to improve the future microbiome of the offspring of mothers with Crohn’s disease, or how It’s the fertilization the main agent in rhizosphere composition.

I hope you enjoy reading this as much as I did making it!
Stay safe, Jose

Good moring y’all!

Today’s digest is relatively short, but rather diverse- from the potential characteristics of scientific tweets readers, through cancer microbiome and horses fecal transplants, as well as endophytes microbiomes in different biomes and plants. Also, if you’re still unfaimilar with the ‘Talking about Biotech’ podcast (by Kevin Folta), I highly recommend to add it to your list. The latest episode talks, of course, about the Corona outbreak, and if you’ll go a bit earlier you will find plenty interesring and insightful episodes.

And lastly- pls stay safe! in Israel, as in other parts of the world, conferences are being cancelled, group meetings are rescheduled and we were highly encouraged to work from home (go bioinformatics!). Remember- there is not a single experiment that is more important than your and your love ones health.

Good morning/afternoon all microbiome lovers!

Coming back from 4th Thunen Sumposium on Soil Metagenomics (11-13.12, Germany), the first section of today’s digest will highlight some work emphasized during the conference. Pay special attention to Amy Willis work (UoW) dealing with amplification bias in 16S analyses, among else. You are more than welcome to check the conference and the bioinformatic workshops schedule, as you’ll find interesting, inspiring and useful studies and tools that are relevant even if you’re not working on soil-associated habitats.

Have a great day!

Soil Metagenomics insights

Rigorous Statistical Methods for Rigorous Microbiome Science, Amy Willis, mSystems. I highly recommended to be familiar with the Willis lab works and tools, for all of us working with amplicon-sequencing and metagenomics. Amy was kind enough to upload her conference materials to github, using this link.

Additionally, They just started a bio-statistics blog, so check this as well.

Consistent and correctable bias in metagenomic sequencing experiments, Michael R. McLaren, bioRxiv

Understanding and interpreting community sequencing measurements of the vaginal microbiome, HL Berman, BJOG

These two papers are from Benjamin Callahan group (NCSW). Even though he wasn’t at the conference, his work (et al.) were mentioned several times by other speakers, so I decided to emphasize these two papers.

The MG-RAST API explorer: an on-ramp for RESTful query composition, Tobias Paczian, BMC Bioinformatics. Folker Meyer, one of the developers of MG-RAST and its head, was actually at the conference with a great talk about both MG-RAST and the importance of pipelines and common workflow language in computational biology. Check this link and the MG-RAST API explorer, making it so much simpler to search, filter and efficiently use MG-RAST.

TerrestrialMetagenomeDB: a public repository of curated and standardized metadata for terrestrial metagenomes, Felipe B Correa, bioRxiv. An amazing tool for searching and filtering soil-associated metagenomes in different databases, plus simple codes for downloading. Take a look at more papers from the de-Rocha group.

Good morning everyone!

This post is written from lovely NYC, quite a distance from my hometown in Israel. If you’re working on microbial ecology in the city and care for a cup of coffee (on me!) and a rather interesting chat about science, entreprenurship and agriculture- please contact me via barakdror@outlook.com or just find me on Linkedin.

Today post will feature highly recommended podcast, a great antimicrobial resistance review paper, Cocaine effect on gut microbiota, some cool bioinformatics tools papers, fascinating animal microbiome studies and more.

Resources and Podcast

I’m a huge fan of the This Week in Microbiology podcast. On their 201 episode the team hosted Prof. Mark Martin (U of Puget Sound) with some great list of papers for 1st year undergrads- but it is a great opportunity to read about general concepts and direction in micrboiology. I truely enjoed both the episode and the recommended papers.
