This Superbacteria can Withstand Enough Radiation to Kill a Person - Universe Today

universetoday.com/170266/this-

Universe Today · This Superbacteria can Withstand Enough Radiation to Kill a PersonNature is filled with examples of extreme life (aka. extremophiles), which are so-called because they can withstand extreme conditions. These include organisms that can survive in extremely dry conditions, extreme temperatures, acidity, pressure, and even the vacuum of space. The study of these organisms not only helps scientists learn more about the kinds of environments … Continue reading "This Superbacteria can Withstand Enough Radiation to Kill a Person"

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.

Extreme environments are coded into the #genomes of the organisms that live there theconversation.com/extreme-en

Environment and #taxonomy shape the genomic signature of #prokaryotic extremophiles nature.com/articles/s41598-023

"The expectation was that all the clusters would be along taxonomic lines: #bacteria grouped with bacteria, and #archaea grouped with archaea. To our great surprise, this was not always the case... The only obvious commonality was that they were heat-loving #extremophiles."

New Protists Described in 2023 isep-protists.com/post/new-pro

From termite symbionts with rotating heads to amoeboid cactus-dwellers, from cannibalistic ex-algae to ciliates thriving in saturated brine, 2023 brought us numerous new discoveries of weird and wonderful microbial eukaryotes. Let's explore some of the most interesting finds in this end of year recapitulation (by yours truly).

As children we thought it was an alien invasion. The "things" could somehow move around. We often found it on the patio. Here they marched from the fields onto the path.😉
Indeed, #Nostoc or star jelly / spit of moon is a fascinating colony-building #cyanobacteria capable of #photosynthesis. Nostoc is a master of survival, symbiotic with #plants, #fungi, and other #bacteria. It can help moss to survive on bare rocks.

After long or heavy rainfalls you can find weird gelatinous pieces on paths. They are dark green, sometimes nearly black with humidity and get brown if they dry. They remind algae. The movement is made by the rain.
Photo 4: Zoom on the alien, which is a glibbery, dark green colony of cyanobacteria. The Zoom shows how moss begins to live on a path which is normally to dry for it. The common name of cyanobacteria was blue-green algae. They are one of the oldest living beings on Earth. For them, Homo sapiens must be the alien.
Foto 3: Approaching such a green thing shows gelatinous structures looking like a lichen.
Photo 2: one of these "things" shows that the dark blotch is indeed something with a structure, a colony!

#Genomic insights into the mystery of #MouseMummies on the summits of #Atacama #volcanoes cell.com/current-biology/fullt

"#Scientists had expected life at the summits to be limited to #microbes... Instead a new analysis suggests that #mice found living on the peaks aren’t outliers but representatives of a fairly persistent population."

Extreme habitats: #Microbial life in Old Faithful Geyser phys.org/news/2023-10-extreme- #microbes #extremophiles #bacteria

An active #microbiome in #OldFaithful geyser: Lisa Keller et al. academic.oup.com/pnasnexus/art

"T. ruber is the most abundant #bacterium residing in Old Faithful, making up over 60% of the microbial population. As a #chemoautotroph, it makes its own energy, not only for its own sustenance, but also to the benefit of the rest of the microbial community."

Asbestos has long been the retroactive bane of building constructors and environmental engineers alike, due to contamination and spread.

Now, University of Pennsylvania scientists have found that extremophiles such as D. palaeochoriense are able to break down the iron in asbestos through anaerobic respiration and reduce its toxicity massively.

Learn about different kinds of #microbes and #extremophiles, as well as some of the relatively recent interplanetary discoveries that help make #panspermia—a concept that suggests life may have been seeded between our local #planets or throughout the #universe through #meteorite impacts, #interstellar dust, or other #space debris—a credible hypothesis.
