In Some Water Bodies of #Bavaria, a Ban on Bathing Has Been Introduced Due to the #Multiplication of #Cyanobacteria

Due to anomalous heat, an official ban on bathing has been introduced on a number of lakes in Bavaria. A mass multiplication of toxic cyanobacteria has been recorded on #Altmühlsee, #Ebertshausener See, and #Ebenhausener Weiher. to do?

Working out how photosynthesis evolved.

"The most recently identified Gloeobacteria species, Anthocerotibacter panamensis, harvests light using a different set of proteins than modern cyanobacteria — but converts sunlight into chemical energy within protein complexes that vary only slightly from those in other Gloeobacteria. These traits add new color to the long, strange evolutionary story of photosynthesis."

An Early Step on the Long, Strange Road to Photosynthesis | Quanta Magazine

An ancient lineage of cyanobacteria is helping biologists uncover an early evolutionary stage of the mind-boggling process that turns light into life.

One of the earliest great extinctions in Earth's history may have been caused not by an asteroid or a volcano but by oxygen itself, when tiny photosynthetic microbes slowly filled the air with a gas that was poison to much of the anaerobic life that ruled the planet long before us

Around 2.4 billion years ago, the air over Earth began to change. Microbes in the oceans, the cyanobacteria, had been running a chemical reaction that split water and released oxygen as waste. For a long time that oxygen was mopped up almost as fast as it was made. Then the sinks filled, and it began […]

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.

Surprising Green Ice on Lake #Lipno: #Cyanobacteria Bloom in Mid-Winter https://www.bc.cas.cz/en/news/news-detail/7816-surprising-green-ice-on-lake-lipno-cyanobacteria-bloom-in-mid-winter/

"An unusual natural phenomenon appeared on Lake Lipno in #SouthBohemia, #Czechia, at the end of 2025. Large amounts of cyanobacteria in the water caused the ice to turn green... After refreezing, a particularly distinctive feature was the formation of so-called cyanobacterial eyes - areas of clear ice above dark cyanobacterial aggregates caused by differences in the absorption of solar radiation."
