Mars Plant Growth from Cyanobacteria-Based Fertilizer You’re the Lead Botanist on the third human mission to Mars whose primary job involves growing food for the crew throughout the long mission. While you’re very familiar with the infamous “poop potatoes” from the 2025 film The Martian, the greatest minds in science had since devised a more efficient, and less messy, method for growing food on Mars: cyanobacteria.

25.707,-67.763 Salar de Antofalla is a salt flat in the Andes of Catamarca Province in the Argentine Northwest. The salt flat contains systems of oncoids that grow in the interface between proper salt flat and an adjacent wetlands. The geology surrounding the southern part of Salar de Antofalla is made up of continental sedimentary rock that deposited from Late Eocene to Early Pleistocene times. (Closest article: Salar de Antofalla, ~1.98 miles; found via undefined-mile search) Verify on Wikipedia: Salar de Antofalla Plant a tree by exploring more

I LOVE expanding my etymological prowess!

Do you know what an #oncoid or #oncolite is? I had no idea they existed!!

So cool.

Как находка в пещере в Нью-Мексико поменяла наши представления о том, на каких планетах возможна жизнь - BBC News Русская служба Ученые, исследующие пещеры Карлсбад в Нью-Мексико, обнаружили микроорганизмы, которые осуществляют фотосинтез в полной темноте с помощью света, близкого к инфракрасному диапазону. Это означает, что планеты, где возможна жизнь, можно искать у более холодных звезд, которых во Вселенной гораздо больше.

These drinkwater bottles with the bottom taken out, are partially perforated. These perforarions are covered with a 50 Micron mesh fabric to avoid anoxic conditions as much as possible and keep algae out. They will be held in place by a pvc tube on the lake bed. Every two weeks the collection jars must be replaced by new ones. We expect to see buoyant Microcystis or Dolichospermum colonies in the collection jars in due time....or not.

This study shows O2-producing #cyanobacteria likely prospered in silica- and iron-rich ancient oceans prior to the emergence of free O2. Silica and day-night light cycles helped the #microbes to overcome toxicity effects caused by oxygen radicals.

This is the ditch #scum I'm talking about. 2nd photo is made 8 hours later. The differences are minute. Some patches have connected. These #Oscillatoria glide around forming mats on the bottom of ditches and start to float when they produce oxygen bubbles trapped within the patch.

Big cilliate and a smaller one

Oscillatoria is a filamentous cyanobacteria that glides (motile) It forms dark floating scum

Scooping scum out of a ditch is fun! It looks like a sewer has discharged and fecal matter floats, but it's not. It's mostly #cyanobacteria and full of life. The big #ciliate has ingested #Oscillatoria #microscope
