Thank you, it was really fun! =)

I had a lot of fun helping to organize VOLT's annual retreat. Great science, fun workshops and interesting talks. I'm so happy my escape rooms worked so well! And karaoke was insane!

Thank you, @voltcenter.bsky.social! It was really amazing! 🧪

Using #cyanobacteria in #architecture to build structures that produce oxygen and sequester carbon in urban environments? That's an amazing concept!

There indeed is a lot of papers on microbial defense/anti-defense systems coming out that were run under conditions that are so foreign that they leave you wondering if that's really how they work.

We do need to test these systems more! 🧪🦠🔬

Our new paper on archaeal anti-CRISPRs is out in
@Nature (@SpringerNature)! 🔗 rdcu.be/eh1Ma
Using a native virus–host model (SIRV2–S. islandicus), we show that overexpression in foreign hosts can lead to false positives.

Very interesting review estimating that cyanobacteria were already prepared for aerobic metabolism before oxygenating the global atmosphere!

A geological timescale for bacterial evolution and oxygen adaptation

Microbial life has dominated Earth’s history but left a sparse fossil record, greatly hindering our understanding of evolution in deep time. However, bacterial metabolism has left signatures in the ge...

Wow, so now we're "deforesting to save the climate"? And they have the nerve to call it "Liberty Avenue"? This is unbelievable.

And they're still increasing their emissions. This is absolutely insane. 🧪

Wow, they found fungal hyphae inside the sheaths of nitrogen-fixing cyanobacteria! Usually with these types of symbiosis it's the other way around, with bacteria growing inside their host. This is supercool!🧪

Fun fact: they're green because they steal the chloroplasts of the algae they eat. The chloroplasts become their symbionts and do photosynthesis for them in exchange for some essential nutrients. That process is called "kleptoplasty".

Peatland #conservation and #restoration are essential for the health and stability of our planet. Protecting vital ecosystems like this must become a higher priority.

Danillo O. Alvarenga @danilloalvarenga.bsky.social · Jan 26

They fight #ClimateChange by sequestering #carbon, regulate water flow and provide habitats for unique species. But peatlands are under threat from drainage, land-use changes and rising temperatures.

Danillo O. Alvarenga @danilloalvarenga.bsky.social · Jan 26

#Peatlands are among the most important ecosystems on Earth. They cover only ~3% of the planet, but they store more carbon than all the world’s forests combined.

#Cyanobacteria are blue-green #bacteria, but this video was captured using a fluorescence #microscope. That makes their chlorophyll shine with this red glow, making it easier to find them inside the #moss #leaves.

Danillo O. Alvarenga @danilloalvarenga.bsky.social · Jan 26

So what we have here is nitrogen-fixing #cyanobacteria in symbiosis with a #peat #moss. These bacteria live inside liquid-filled dead cells (called hyalocytes) in the leaves of the moss. They can move around inside the cells by following the water flow.
