by Clio Morata de Jong and Nico Morales — In the realm of natural mind control, few phenomena are as gripping – literally – as the death grip of the parasitic fungus in the genus Ophiocordyceps. This fungus doesn't just kill its carpenter ant hosts; it transforms them into instruments of fungal propagation. Read more →
CRISPR-Based Metabarcoding
Noteworthy — Microbes are abundant and very diverse. But acknowledging their significance in our biosphere has taken time and relied on curiosity, hard work, and the development of technologies to access, identify, and study microbial communities. Read more →
Lost & Found #6
by Christoph — In this episode, again three bookmarks that came to my attention while cleaning up our account on 𝕏 (formerly Twitter) and that are not at all out of date. Give them a brief look and judge for yourself. Here is Lost & Found #6. Read more →
Pseudouridine Stabilizes tRNA
Noteworthy — The modified nucleoside pseudouridine has many reasons to be considered a star among post-transcriptional RNA modifications. It was the first to be identified, in 1960. Incorporating it into mRNA vaccines was a big reason for their success. And it also shows up in numerous antibiotics. Now there's more. Read more →
Evolution of Ant-Fungus Farming
by Mechas — Agriculture has triggered enormous changes in human society. But it is not unique to humans. Read more →
Living Construction Materials
Noteworthy — The production of cement – used as a binder in concrete – has a high carbon footprint, accounting for 5%–8% of anthropogenic CO2 emissions. The search for alternative materials with reduced impact on global warming has come up with some interesting options. Read more →
Cultivating the Ancestors (4|4)
by Christoph — Having one or two 'Asgard' archaea under the microscope – after having cultivated them with great effort and even more patience – and looking them in the face is exciting, but a bit unsatisfying if they are cousins. Are they mavericks or rather typical for "Lokis"? Here are the portraits of two more distant relatives, both also cousins: Margulisarchaeum peptidophila HC1 and Flexarchaeum multiprotrusionis SC1.

Of Aerobes and Anaerobes
Noteworthy — When first introduced to microbes, we quickly learn to divide them into aerobes and anaerobes. Then we qualify those titles with modifiers to yield such classes as facultative anaerobes, obligate aerobes and strict anaerobes. Read more →
Cultivating the Ancestors (3|4)
by Christoph — There was joy, even excitement among archaeologists when the first images of Promethearchaeum syntrophicum MK‑D1 made the rounds. This sense of joy deepend still when images of its cousin Lokiarchaeon ossiferum Loki-B35 were added a little later. The ancestors suddenly got their own faces, literally, and were no longer only vaguely recognizable from genome sequences! Read more →
Promising New Antimicrobials
Noteworthy — Amid the turmoil and uncertainty of our times, one fact is undeniable: microbes continue to evolve. Read more →
