NewsStudy tracks Atlantic Meridional Overturning Circulation using benthic foraminifera
Scientists investigated how the weakening of Atlantic Meridional Overturning Circulation is connected to the ventilation of the shallow ocean. Using benthic foraminifera, the team was able to reconstruct changes in the oxygen content of the oxygen-minimum zone over 27,000 years.

NewsStudy uncovers the hidden emerging pathogen behind Aspergillosis cases in Japan
Scientists have discovered the ancestral evolutionary links of Aspergillus latus strains through in-depth genome sequencing analyses.

NewsOmicron strain BA.2.86 emergence ‘defies natural explanation’
A researcher investigating the origin of the BA.2.86 lineage found that sporadic cases were identified in multiple, geographically distant locations around the world during its initial appearance in the summer of 2023.

NewsDual lifestyle plant fungus turns ally, protecting cereal crops against harmful Fusarium infections
A plant-friendly fungus that colonises cereal crops can protect the plants against harmful fungal infestations, a new study reveals.
-
NewsSimple rules govern soil microbiome responses to environmental change
New research shows that a deceptively simple mathematical model can describe how the soil responds to environmental change. Using just two variables, the model shows that changes in pH levels consistently result in three distinct metabolic states of the community.

NewsSwiss genome of the 1918 influenza virus reconstructed
Researchers have decoded the genome of the virus responsible for the 1918–1920 influenza pandemic in Switzerland, revealing that it had already developed key adaptations to humans at the outset of the deadliest influenza pandemic in history.

NewsPrairie dogs carry genes linked to surviving plague
A study of the genetic basis of plague immunity in prairie dogs has broad implications for conservation. By comparing whole-genome sequences, the authors identified genetic variants associated with survivorship.
-
NewsLarge-scale DNA study maps 37,000 years of disease history
A new study maps infectious diseases across millennia and offers new insight into how human-animal interactions permanently transformed our health landscape.
-
NewsHow plants build the microbiome they need to survive in a tough environment
New research points to the idea that under some conditions plants can “curate” their microbiomes—selecting good microbes and suppressing harmful ones—to adapt to their environments.

NewsEstrela brings microbial research to Texas A&M AgriLife Department of Nutrition
Sylvie Estrela, Ph.D., has joined the Texas A&M College of Agriculture and Life Sciences Department of Nutrition as an assistant professor. Estrela’s research focuses on microbial interactions, specifically, the way nutrients can impact bacterial communities.

NewsWith AI, researchers find increasing immune evasion in H5N1
A new analysis suggests that the H5N1 avian influenza virus is evolving clever strategies. Using artificial intelligence tools, researchers analyzed thousands of viral proteins and found that their bonds to protective antibodies have weakened over time.
-
NewsScientists strive to place tens of thousands of previously unknown fungi in the evolution tree
Scientists have received a grant to systematise and describe members of the 95% majority of previously unclassified microscopic fungi, and other eukaryotic organisms not yet included in the current tree of life system.

NewsEvolutionary model for antibiotic resistance reveals dose timing critical to care
The study that uses a “fitness seascape” to incorporate a patient’s dosage schedule into models that predict whether an infection will develop antibiotic resistance has found that inconsistent timing and missing early doses can lead to treatment failure.

NewsScientists report well-preserved fossil blue-stain fungus from the Jurassic
A research team has found well-preserved fossil fungal hyphae preserved within a Jurassic petrified wood from northeastern China, dating back 160 million years.

NewsResearchers uncover genetic keys to the increasing threat of H9N2 avian influenza
A new study has uncovered significant genetic and antigenic diversity among H9N2 avian influenza viruses (AIVs) circulating in poultry across China, highlighting the growing public health risk posed by H9N2 AIVs.

NewsStudy resolves diatom tree of life - and could offer clues to Earth’s puzzle
A new study finds that diatoms evolved slowly for the first 100 million years of their existence. Then, 170 million years ago, they reached an inflection point characterized by a burst of rapid speciation orders of magnitude faster than anything that had preceded it.

NewsRock record reveals oxygenation of ocean may have happened earlier than we thought
Researchers uncover evidence that oxygenation in the ocean—crucial for life as we know it—may have occurred earlier than previously thought, offering new insights into the evolution of our planet.

NewsHow the plague bacillus became less virulent, prolonging the duration of two major pandemics
Scientists have discovered that the evolution of a gene in the bacterium that causes bubonic plague, Yersinia pestis, may have prolonged the duration of two major pandemics. Modifying the copy number of a specific virulence gene increases the length of infection.

NewsAncient remains reveal how a pathogen began to use lice – not ticks – to infect humans
Researchers have analysed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.

NewsYeast reveals how species adapt to a warmer climate
Researchers harnessed the power of experimental evolution with the microbial model system yeast (Saccharomyces spp.) to measure the evolutionary potential of populations to adapt to future warming, in real time and across the entire species tree.
