Metagenomic estimation of absolute bacterial biomass in the mammalian gut through host-derived read normalization | mSystems In this study, we asked whether normalization by host reads alone was sufficient to estimate absolute bacterial biomass directly from stool metagenomic data, without the need for synthetic spike-ins, ...

You can get an accurate estimate of total bacterial biomass from stool metagenomes by simply normalizing by host read count, without needing any additional measurements.

Excellent work by UW Master's student Gechlang Tang in @asm.org #mSystems Journal.

Hei kaikki! Minä ja pieni joukko tutkijaystäviä olemme lähdössä elokuussa Turun saaristoon etsimään harvinaisia bakteereita saarten maaperästä. Tutkimusmatkamme on kumivenettä vailla.

Olisiko kellään lainata/vuokrata kumivenettä elokuun ensimmäiseksi viikoksi tutkimusmatkallemme?

Our latest study in collab w/ the Groningen Microbiome Hub team is OUT!

We identified 484 microbial-strain-level associations with 241 host phenotypes, encompassing human anthropometric factors, biochemical measurements, diseases, and lifestyle. And more!

We are organising a art-science symposium on Memory in Complex Systems in a few weeks in Tampere, Finland! The event is free and open to everyobody! Welcome!

Yle näki lopulliset kriteerit vanhojen metsien suojeluun – kova kritiikki ei näytä kääntäneen hallituksen päätä Hallitus ei ole muuttanut ikää ja kuolleen puun määrää koskevia rajoja, joiden perusteella vanhat metsät valikoidaan suojeluun.

Hallituksen kriteerit luonnontilaisista ja vanhoista metsistä eivät hidasta luontokatoa suomalaisissa metsissä. Suojelupäätösten tulee perustua tieteeseen. Näin lausuimme vanhojen metsien kriteereistä viime kesänä. Hallitus pitää aiemmat kriteerit kritiikistä huolimatta. yle.fi/a/74-20148157

Home - Finnish Natural Heritage Foundation Through the Finnish Natural Heritage Foundation, every friend of nature can personally be part of the work for the conservation of old-growth forests.

Here's a great idea for a gift to self or others:

Through Finnish natural heritage foundation, you can buy old-growth boreal forest of pristine bog land to protection. It's a no-nonsense charity that uses 100% of donations in buying land back to nature

Gut microbiome strain-sharing within isolated village social networks - Nature An investigation into the relationship between network structure and gut microbiome composition among people living in 18 isolated Honduras villages reveals that strain-sharing can be mediated by...

This is my absolute favorite piece of recent research and I'm hyped to see it out!

So amazing to see how human microbiomes live within the ecological landscape structured by a social network of one single village! Ecosystems nested within social sytsems
