🦠#Microbes are in a constant battle for survival! Researchers from @LeibnizHKI @unijena @microverse_exc @unibayreuth discovered how the plant pathogen Pseudomonas syringae uses a chemical radar to detect and eliminate predatory #amoebae .The #bacteria produce harmless molecules that the amoebae modify, revealing their presence. P. syringae detects this and produces toxic substances to eliminate the predator. This mechanism could inspire new drugs and pest control strategies! 💊 @dfg_public #EFRE

Pink snow tints the edges of Antarctica english.elpais.com/science-tec

"The #algae that covers Mount Reina Sofía in patches is Sanguina nivaloides, a species first described in 2019. The meaning of its scientific name in Latin is eloquent: blood in the snow. Each creature has a single cell, about 20 thousandths of a millimeter in size, with a molecule inside that gives it its characteristic red color: #astaxanthin... the same pigment that produces the color of salmon"

Ancient marine organism's dual-layer structure reveals both past and present ocean environments phys.org/news/2025-02-ancient-

A cosmopolitan calcifying benthic #foraminifera in agglutinated disguise as a geochemical recorder of coastal environments pnas.org/doi/10.1073/pnas.2413

"This species has a remarkable hidden feature—an inner shell made of calcium carbonate beneath its outer layer of gathered particles... [this] made them an excellent recorder of environmental conditions."

Yo dawg, there are #microbes living in your #nuclear #reactor.

MDPIDirect Meta-Analyses Reveal Unexpected Microbial Life in the Highly Radioactive Water of an Operating Nuclear Reactor CoreThe pools of nuclear reactor facilities constitute harsh environments for life, bathed with ionizing radiation, filled with demineralized water and containing toxic radioactive elements. The very few studies published to date have explored water pools used to store spent nuclear fuels. Due to access restrictions and strong handling constraints related to the high radioactivity level, nothing is presently known about life in water pools that directly cool nuclear cores. In this work, we investigated the microbial communities in the cooling pool of the French Osiris nuclear reactor using direct meta-omics approaches, namely, DNA metabarcoding and proteotyping based on 16S ribosomal RNA gene sequencing and on peptide analysis, respectively. We identified 25 genera in the highly radioactive core water supply during operation with radionuclide activity higher than 3 × 109 Bq/m3. The prevailing genera Variovorax and Sphingomonas at operation were supplanted by Methylobacterium, Asanoa, and Streptomyces during shutdown. Variovorax might use dihydrogen produced by water radiolysis as an energy source.

SpringerLinkLiming enhances the abundance and stability of nitrogen-cycling microbes: the buffering effect of long-term lime application - Biology and Fertility of SoilsLime application (liming) has historically been used to ameliorate soil acidity in grasslands. Liming effectively improves soil pH, plant productivity, and soil physicochemical properties, but the long-term impact of acidity control by liming on key microbial nitrogen (N)-cycling genes in semi-natural grasslands is unknown. We investigated the effect of 65 years of liming on N-cycling processes in the limed and control plots of the Ossekampen long-term grassland experiment in the Netherlands. These plots have not received any other fertilizers for 65 years. Soil sampling and nitrous oxide (N2O) emission measurements were conducted three times in spring and four times in summer, and quantitative real-time PCR was performed to determine the absolute abundances of N-cycling genes, including ammonia-oxidation (amoA-AOB, amoA-AOA, amoA-comammox), denitrification (nirS, nirK, nosZ), nitrate ammonification (nrfA), and N-fixation (nifH) genes. Long-term liming increased the absolute abundances of nitrifiers, denitrifiers, and nitrate ammonifiers. Soil N2O emissions did not differ significantly between liming and control treatments. Additionally, liming had a buffering effect that maintained the population of N-cycling microbes against seasonal variations in abundance. Our results indicate that improving soil acidity through liming potentially facilitates microbial N-cycling processes without increasing N2O emissions.

A global comparison of surface and subsurface microbiomes reveals large-scale biodiversity gradients, and a marine-terrestrial divide science.org/doi/10.1126/sciadv

"In an ambitious 8-year census, a team has found an astonishing diversity of #microbes living beneath our planet's surface, deeper than anything we've discovered prior... it has turned up lifeforms as deep as 491m below the ocean floor, and even further below land: 4,375m deep"

Mapping #Antarctica's hidden ice-free lands: A blueprint for conservation phys.org/news/2025-01-antarcti paper: nature.com/articles/s41597-025

"The ice-free lands are home to uniquely adapted flora including micro-forests of #lichens, #moss, and two flowering plants, Antarctic hairgrass and pearlwort. They also sustain a variety of #mites, #springtails, #tardigrades, #nematodes, #algae, and #microbes. #Seabirds have established breeding colonies in these areas too."

How tiny algae shaped the #evolution of giant clams phys.org/news/2025-01-tiny-alg nature.com/articles/s42003-024

"T. maxima have evolved more genes for sensors to distinguish friendly #algae from harmful #bacteria, #viruses... it has tuned down some of its immune genes in a way that likely helps the #animals tolerate #microbes... As a result of the weakened #ImmuneSystem, its genome contains a large number of #TransposableElements left behind by viruses. These aspects highlight the tradeoffs of #symbiosis"
