Greetings from Wiltshire, England!

Today’s digest brings a little bit of everything. We’ve been cataloguing the latest COVID-19 publications during this pandemic, and today I’m please to bring you a paper combining both COVID-19 and microbiome research!

Elsewhere, there are plenty of environmental microbiome publications, including a great paper on the challenges of studying microbiology in space, an analysis of how aerosols spread COVID-19 and other infectious agents in dental practices, and plenty of articles on various aspects of soil microbiomes.

I hope everyone’s coping well during these times. On a personal level, I’m delighted to be returning to the lab this week to resume my PhD research into gut microbiomes and cancer. I’m glad to be back, but worried about how my pipetting skills have suffered during my time off!

Stay safe, and happy reading!

Hi everyone! This is my first contribution to the daily digest, and I’ll follow others’ lead by starting with the latest preprints concerning Covid-19. Away from the ongoing pandemic, some of the highlights include a look at how commensal gut microbes interact with pathogens, and an insight into deep sea oceanic crust microbiomes.

It seems to be a relatively quiet day today, so I’ve included an article from the University of Bristol which looks at how nanoscopic pillars on the surface of some insect wings protect them against bacteria. Perhaps only loosely a microbiome paper, but it’s worth a read for its electron microscopy alone!

COVID-19

Structure of the SARS-CoV-2 spike receptor-binding domain bound to the ACE2 receptor – Lan et al. – Nature

Preprint: Atazanavir inhibits SARS-CoV-2 replication and pro-inflammatory cytokine production – Fintelman-Rodrigues et al.

Good morning everyone! (and apologies for the delay, a technical issue regarding the system time difference between Israel and US Pacific time :)).

Due to yesterday extremely rich digest, today’s post will be short- but diverse! Spreading from gut microbiome in infants and beetles, to the effect of microbial communities on sweet wine quality. As a bonus for the upcoming weekend, at the end of the post you’ll find a link to an article listing 10 recommended biotech podcasts.

Happy holidays for all!
