Noteworthy — Fungi are wonderfully diverse and versatile microorganisms. And it is perhaps this versatility that makes them so adept at forming symbiotic relationships with other organisms. Mycorrhizae or endophytic fungi, for example, inhabit plant tissues where they reside within or between plant cells. Read more →
Our Built Environment Microbiomes
by Mechas — There is no doubt that our understanding of microbiomes – those microbial communities in practically any environment – has increased in recent years. Research now covers almost any conceivable niches, from cow rumen or the human gut, to numerous human-made ecosystems. Read more →
Making a Living in the Nucleus
Noteworthy — When it comes to intracellular pathogens, we usually think of those that remain inside a membrane-enclosed vacuole and those that escape into the cytoplasm. Much rarer are cases of parasite that make a living inside the nucleus. Read more →
Lost & Found #5
by Christoph — When you leave 𝕏, it means that among the “bookmarks” you take with you, you will also come across some that contain images or videos that are mainly nice to look at and even entertaining. As in 'Lost & Found #4', two such are included today in 'Lost & Found #5'. Read more →
A Fungus that Reduces Methane Emissions
Noteworthy — We face unprecedented rising global temperatures, a crisis driven largely by the burning of fossil fuels. But other sectors, like the livestock industry, also contribute by producing large amounts of greenhouse gases. Read more →
Wait, What? extracurricular DNA (eDNA)
by Christoph — Among biologists, DNA is a household term, the acronym for desoxyribonucleic acid, which hardly anyone pronounces in full. But can you find your way around the zoo of prefixes that are in use and in most cases are not separated from 'DNA' by a hyphen, as for example in Z-DNA? cccDNA, rcDNA (ocDNA), mtDNA, ecDNA, cDNA, bDNA, gDNA (chrDNA), kDNA, xDNA, rDNA, tDNA, ssDNA,… and eDNA.

Deep-Sea Viruses Wreak Havoc
Noteworthy — Absorbed in our daily activities and concerns, personal, local or global, we remain largely unaware of how life unfolds on this planet. Viruses, and especially those in our vast oceans, play a major life-defining role. Read more →
Watching the flagellar motor at work
by Lucas Le Nagard — Swimming E. coli typically cover a distance equivalent to the radius of a human hair each second. It might not seem very impressive… But for a 2 µm bacterium, it corresponds to 10 body lengths per second! Much better than the swimming speed of our best athletes, which barely exceeds one body length per second. So, how does E. coli achieve this? Read more →
Bacterium Linked to Depression
Noteworthy — The human microbiome – the collection of microbes associated with our bodies – is variable, adapts to its host, but, most importantly, is increasingly recognized as important for our health and physiology. The sheer number and diversity of microbes, not to mention their interactions and activities, makes the study of the microbiome complex. How, then, can we understand what these microbes are doing?

Lost & Found #4
by Christoph — When you leave 𝕏 (formerly Twitter), it means that among the “bookmarks” you take with you, you will also come across some that contain images or videos that are mainly nice to look at and even entertaining. Two of these – no, none of the infamous cat pictures – are included today, in 'Lost & Found #4'. Read more →
