NewsNew biobank decodes survival secrets of extreme acid mine drainage microbes
Over 97 percent of microorganisms in acid mine drainage have never been cultured, leaving their metabolism and adaptation strategies locked as “microbial dark matter.” Now, a new culturomics‑driven resource called the Microbial Biobank of AMD (mbAMD) changes that.

NewsPathogens survive conditions on extraterrestrial locations
Microorganisms from our planet could survive on celestial bodies where water is present, such as Mars, reveals a study focusing on simulated space conditions. Our immune system reacts less effectively to pathogens that have undergone such a simulated space journey.

NewsOrganized microbial ‘workforces’ keep Earth’s underground biosphere running
By studying life deep inside a former gold mine, scientists uncovered evidence that Earth’s hidden biosphere operates less like a random collection of microbes and more like an organized workforce. From site to site, the ecosystems were incredibly different from one another but largely stable through time.

NewsÖtzi and his microbiome: a 5,300-year-old relationship
Researchers have obtained a detailed picture of the microbial community associated with the Iceman mummy Ötzi. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts.

NewsExtreme adaptation helps Dead Sea single-celled organisms to swim
Researchers have described in detail a structural adaptation supporting one of the Dead Sea’s few hardy inhabitants — a single-celled archaea called Haloarcula marismortui (H. marismortui). They characterized the proteins that form the archaeal filament, a long tail-like structure essential for movement.

FeaturesBottling the extremes: culturing the hidden microbiomes of caves and deserts
Imagine an environment so extreme that most life cannot survive: a pitch-dark cave deep beneath the mountains of Northern Spain, or a hyper-arid desert in Chile where rainfall is virtually non-existent. These are not lifeless wastelands. Beneath cave walls and within the dusty top layer of desert soils, thriving communities of cyanobacteria, green algae, and fungi quietly engineer their ecosystems: fixing carbon, weathering rock, and cycling nutrients in conditions that would defeat most organisms on Earth.

NewsResearchers investigate soil microbes from around the world for new antibacterial drugs
A team of researchers is looking to nature to find microbes that can be used to create new antibiotics to treat the growing threat of drug-resistant bacteria. They will screen soil microbes from around the world to hunt for sources of new antibacterial drugs.

NewsLAMECS 2026 set to bring the next generation of microbiologists to Manchester
The future of applied microbiology takes centre stage in Manchester next month as the Letters in Applied Microbiology Early Career Scientist Research Symposium (LAMECS) returns for its fifteenth year.

NewsStudy uncovers new kind of cold sensor
Investigators studying a bacterial protein have identified a new mechanism of sensing cold temperatures. The finding points to the possibility that this same type of mechanism exists in other organisms, including humans, and may have relevance for disorders involving faulty temperature regulation.

NewsSelf‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Researchers who previously identified a highly unusual RNA virus in a high-temperature hot spring ecosystem searched for distinct types of self-replicating RNAs in a similar extreme environment, and a novel circular RNA replicon was identified within the microbial community inhabiting the hot spring.

NewsViruses found in Antarctic air, including some new to science
It may seem stark and lifeless, but the air around the remote sub-Antarctic island of South Georgia contains viruses, including some that are new to science. Using metagenomics, researchers discovered that South Georgia harbours a diverse and dynamic airborne viral community.

NewsSalty soils slow biochar aging but limit beneficial microbes, study finds
A new study reveals that increasing soil salinity can significantly slow the aging of biochar, a widely used soil amendment, while also suppressing the microbial communities that help drive its environmental benefits.

NewsLife forms can planet hop on asteroid debris – and survive
The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact, a study shows. It means microorganisms can survive more extreme conditions than previously thought, including launch across space after major impacts.

NewsDynamic duo of bacteria could change Mars dust into versatile building material for first human colonists
Scientists are investigating a bacterial co-culture mixed with Martian regolith as a potential feedstock for 3D printing on Mars. At the intersection of astrobiology, geochemistry, material science, construction engineering, and robotics, this synergistic system could revolutionize the potential for construction on the Red Planet.

NewsHeatproof microbes reveal molecular secrets of nature’s hottest recycling system
This study reveals how thermophilic bacterial communities withstand temperatures of up to 87°C by remodeling their molecular machinery. Scientists uncovered a heat-defense network centered on heat shock proteins that refold damaged enzymes and preserve protein structure.

NewsFats provide clues to life at its limits in the deep sea
Extreme conditions on the ocean floor include high pressures and salinities, as well as extreme pH values and a limited supply of nutrients. A team of researchers has now been able to detect microbial life in two newly discovered mud volcanoes with very high pH values.

NewsMicrobes at Red Sea vents show how life and geology shape each other
A new study led by King Abdullah University of Science and Technology (KAUST; Saudi Arabia) Professor Alexandre Rosado has revealed an unusual microbial world in the Hatiba Mons hydrothermal vent fields of the central Red Sea, a site first discovered by one of his co-authors and colleagues, Assistant Professor Froukje ...

NewsYeast proteins reveal the secrets of drought resistance
A new study in Cell Systems helps explain how organisms can come back from desiccation (the removal of water or moisture) while others fail by looking at the cell’s proteins. In the first survey of its kind, a team of researchers profiled thousands of proteins at once for their ability to survive dehydration and rehydration.
