#Cyanobacteria fix carbon and secrete polysaccharides, the slime they move around on. These are degraded by a row of other bacteria which live of the sugars. The heterotrophs exchange vitamines to reduce individual costs of production.

IT'S OUT!!! Digitally, on Amazon, at least. More platforms and the paperback coming this month.

Blamed for a toxin poisoning the air, Joe is leaving the Bay Area with his 18-month-old daughter. He's trapped in Oakland. Most of the city wants him dead.

🧑‍🔬✨ Meet the Speakers of Soapbox Science Brussels 2025! ✨🧑‍🔬

🔊 Say hi to the brilliant Nora Colson, PhD researcher at Hasselt University — working at the crossroads of #spacescience and #sustainability.

🛰️ Nora’s research explores an unexpected partnership: diamonds and #cyanobacteria! Her mission? Finding innovative ways to produce #hydrogen fuel for space missions, paving the way for a greener future beyond Earth.

📅 Catch her live on June 28th, 2PM, at Carrefour de l’Europe / Europakruispunt.

"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

#Lichens are symbionts. There is a #fungal component (most are about 90 percent fungus) and a photosynthetic component (#algae or #cyanobacteria). Whether lichens can survive on #Mars 🔴 depends on the species. https://arstechnica.com/science/2025/04/lichens-can-survive-almost-anything-and-some-might-survive-mars

Lake Hood outside Ashburton has been closed due to cyanobacteria. It's a man-made lake in a development offering luxury lakefront properties. While it's surrounded by one of the most intensively farmed areas of New Zealand, the story doesn't mention farmers.

So far two people have been poisoned by toxic algae so the district council has made the decision to close the lake entirely.

A geological timescale for bacterial #evolution and oxygen adaptation https://www.science.org/doi/10.1126/science.ADP1853

"the earliest aerobic transition occurred in an ancestor of photosynthetic #cyanobacteria, indicating that the ability to utilize trace amounts of oxygen may have allowed the development of genes central to oxygenic #photosynthesis."

Autotrophs are organisms which use pigments for photosynthesis by absorbing light at specific wavelengths. The dominant chlorophyll-a absorbs #light in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why #algae is green. Phycocyanin, an accessory #pigment in #cyanobacteria, absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.
