Good afternoon all!

Today’s digest is a bit on the lighter side, nevertheless, there are some great papers to sink your teeth into.

Those with an interest in tropical diseases will want to read an investigation into the three-way relationship between humans, their microbiotas and the protozoan cause of Chagas disease.

History buffs, and fans of the epic novel ‘Romance of the Three Kingdoms’ may be interested by an analysis of the soil microbiome of the Jinsha relic, which is found at the site of the former Chinese Shu state capital.

For those more philosophically inclined, there is an interesting discussion on the impact of human space activity on the search for extra-terrestrial life. So that’s ancient history and space-age wizardry all covered in today’s rather modest digest. What more could you want?!

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!
