“… [U]rban floods are not merely hydraulic events; they also transport sewage, pathogens, and other contaminants across streets and communities, leading to significant public health risks…
How do we quantify microbial contamination in near real time during a flood event, when emergency conditions make field sampling unsafe, sparse, or even impossible?...
[The authors] explored whether Earth observation data, combined with machine learning, could bridge this critical monitoring gap. By combining Landsat-derived water surface temperature, machine learning, a coupled MIKE+ Flood–ECO Lab hydrodynamic–ecological model, and Quantitative Microbial Risk Assessment (QMRA), [they] estimated microbial concentrations (𝘌. 𝘤𝘰𝘭𝘪), simulated their fate and transport during floods, and quantified the associated human health risks.
The takeaway: predicting flood risk isn't just about where the water goes; it's about what it's carrying and who it puts in harm's way. Earth observation and machine learning can help close that gap when it matters most, during the emergency, not weeks after…”

The #microbial #diversity of #dynamic #ecosystems can today be assessed using more efficient methods. M. F. Peña-Valencia et al. (2026) identified potential #polyethyleneterephthalate (#PET)-degrading #enzymes from #mangrove #soil using #AI, #3D #structuralanalysis and #metagenomics. Some of these enzymes could be assigned to the bacterial genus #Microbulbifer.

In biology/geology "#marinesnow" refers to the #organicdebris of organisms from higher #waterlevels. The #carboncycle thus transfers #CO2 to the #seabed, thus binding the #greenhousegas.
B. Borer et al. (2026) found that #microbial components of this "snow" induce #calciumcarbonate #dissolution in higher waters, reducing their #settlingvelocity and requiring consideration in future #climatemodels.

"#Agricultural runoff provides perfect nutrients for #methanogen growth.
#Fertilizer and animal waste washing into ocean systems creates nutrient-rich zones where these methanogens thrive like never before. #Nitrogen and #phosphorus pollution from farmland creates ideal conditions for explosive #microbial growth in #coastal waters and #DeepOcean areas. These agricultural inputs essentially act as fertilizer for #methane-producing microbes, creating a connection between #IndustrialFarming and atmospheric #GreenhouseGas levels that scientists never fully appreciated.
"Coastal regions near major agricultural areas show the highest concentrations of these supercharged methanogens, with some areas recording methane production levels ten times higher than baseline measurements. The problem compounds itself because areas with intensive farming also tend to have the strongest ocean currents, meaning these fertilized methanogen populations get distributed globally. Every season’s #AgriculturalRunoff creates new opportunities for these microbes to establish thriving colonies in previously stable ocean environments."

"Marine scientists drilling into abyssal ocean floor sediments discovered thriving colonies of this new #methanogen species at depths previously thought to be biologically inactive. These extreme environments, characterized by crushing pressure and complete darkness, harbor #microbial communities that have evolved unique metabolic pathways. According to research published in #NatureGeoscience, these #DeepSea methanogens can survive in conditions that would kill most known life forms.
"The discovery challenges everything scientists thought they knew about where life can exist in Earth’s oceans. These microbes don’t just survive in the deep ocean trenches, they’re actually flourishing and producing methane at industrial scales. Their metabolic processes operate entirely differently from surface-dwelling organisms, using chemical energy sources that most life forms can’t even process."

Much like humans, #microbial organisms can be fickle in their productivity. One moment they’re cranking out useful chemicals in vast #fermentation tanks, metabolizing feed to make products from pharmaceuticals and supplements to biodegradable plastics or fuels, and the next, they inexplicably go on strike.

#Newswire: Swiss start-up Yeastup AG has opened a 1,700 m² industrial food production facility in Lyss, canton of Bern. The plant can process up to 40 hectolitres of spent brewer’s yeast per hour to produce functional food ingredients, including yeast protein and beta-glucan dietary fibre. The yeast protein functions as an emulsifier and egg substitute in food applications.

Complex #life began to develop earlier, and over a longer span of time, than previously believed.
Nee findings indicate that complex organisms evolved long before there were substantial levels of #oxygen in the #atmosphere, something which had previously been considered a prerequisite to the #evolution of complex life.
The #earth is approximately 4.5 billion years old, with the first #microbial life forms appearing over 4 billion years ago.
These organisms consisted of two groups – #bacteria and the distinct but related #archaea, collectively known as #prokaryotes.
Prokaryotes were the only form of life on earth for hundreds of millions of years, until more complex eukaryotic cells including organisms such as #algae, #fungi, #plants and #animals evolved.
Previous ideas on how and when early prokaryotes transformed into complex #eukaryotes has largely been in the realm of speculation. Estimates have spanned a billion years, as no intermediate forms exist and definitive fossil evidence has been lacking.
By collecting evidence from multiple #gene families in multiple biological systems and focusing on the features which distinguish eukaryotes from prokaryotes, researchers were able to begin to piece together the developmental pathway for complex life.
They obtained evidence that the transition began almost 2.9 billion years ago – almost a billion years earlier than by some other estimates – suggesting that the nucleus and other internal structures appear to have evolved significantly before #mitochondria.
The process of cumulative complexification seems to have taken place over a much longer time period than previously thought.
