"Upon wetting, M. vaginatus begins migrating toward the surface within minutes, moving within the tunnels. This enables cyanobacteria to secure soil particles and thrive in arid environments."

"Despite resembling a lichen's vegetative tissue, their sample had an unexpected feature: it was made of interwoven cyanobacterial filaments that enclosed fungal hyphae. Both partners turned out to be previously undescribed species, different from those found in #lichens"

There is a giant, vibrantly blue, 9 meter tall, 20 tonne interactive #sculpture celebrating stromatolites (fossil cyanobacteria) in Cornwall, England. The Eden Project houses this fantastic piece of art by Azusa Murakami and Alexander Groves called "infinity blue" made of local clay to celebrate how #cyanobacteria transformed the Earth's early atmosphere by forming oxygen through photosynthesis (represented as huge vapour rings). #art #science

#ClimateCatastrophe
#ExtinctionLevelEvent

Yes, the only other species known to me to have ever been so stupid as to have destroyed their whole biosphere on a global level, are #cyanobacteria in the #GreatOxidationEvent in the #Paleoproterozoic Era.

2.4 billion years and #humanity collectively has an #IQ of these ancient bacteria.

Maybe, it deserves to become extinct?

Cheers!

Bacteria Battled for Iron in Earth’s Early Oceans

Inhibition of phototrophic iron oxidation by nitric oxide in ferruginous environments nature.com/articles/s41561-024

"#cyanobacteria started to colonize shallow waters, exhaling oxygen and pushing #photoferrotrophs offshore... Nitrate-reducing #bacteria may have increased the pressure by producing nitric oxide. As photoferrotrophs were stifled, nitrate reducers could have flourished and continued forming banded iron formations"

Every year, in latitudes far enough north or south, a huge swath of life on Earth senses that winter is coming.

Leaves fall from trees, sparrows fly to the tropics, raccoons grow thick winter coats, and we unpack our sweaters from storage.

Now scientists have shown that this ability to anticipate shorter days and colder temperatures is very fundamental to #life.

Even short-lived, single-celled organisms, #cyanobacteria, can sense day length and get ready for winter.

A Crew Was Searching For Shipwrecks In Lake Michigan—But They Found Something Completely Different

“ • A survey of Lake Michigan located at least 40 large craters on the lakebed.
• Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with marine life.
• Researchers expect to investigate further, seeing how these craters formed and if they’re really sinkholes…"

A sonar image of a few of the sinkholes found at the bottom of Lake Michigan. Earlier this month, scientists with the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory confirmed that circular depressions discovered in 2022 were in fact sinkholes. More than 40 have been found roughly 14 miles southeast of Sheboygan in the Wisconsin Shipwreck Coast National Marine Sanctuary.

Purple-hued cyanobacterial mats cover much of the bottom of Lake Huron's Middle Island sinkhole. Discovered in 2010, Lake Huron's sinkholes have been a hotbed for research ever since. The finger-like forms are caused by gases bubbling up underneath the mat.
Researchers from the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory prepare to deploy a remotely operated vehicle to explore the newly discovered sinkholes in the Wisconsin Shipwreck Coast National Marine Sanctuary. More than 40 sinkholes were discovered 14 miles southeast of Sheboygan in the sanctuary.
