NewsHigh resolution techniques reveal clues to early microbes in 3.5 billion-year-old biomass
A research team has found new clues about the formation and composition of the 3.5bn year old rocks of Pilbara Craton, which contain traces of the microorganisms that lived at that time.

NewsInteractions between flu subtypes predict epidemic severity more than virus evolution
An analysis of influenza virus evolution over 22 years of flu seasons reveals the major drivers of disease transmission and epidemic severity.

News‘Pink berries’ reveal how bacteria survive a viral epidemic
Like humans struggling to get through the COVID-19 pandemic, bacterial cells need social distancing to thwart viruses. But in some situations, such as inside elevators or within the candy-colored bacterial structures known as “pink berries,” staying apart just isn’t feasible. Source: Lizzy Wilbanks “Pink berry” bacterial structures. These ...

NewsScientists uncover protein that evolved with infection machinery in toxoplasmosis
Researchers have identified a protein that evolved concurrently with the emergence of cellular compartments crucial for the multiplication of the toxoplasmosis pathogen.

NewsAncient retroviruses played a key role in the evolution of vertebrate brains
Researchers have reported that ancient viruses may be to thank for myelin - and, by extension, our large, complex brains.

NewsResearchers probe ancient partnership between moss and fungi - and endobacteria
Researchers tracking the subtle but distinct ways a moss interacted with its fungal neighbors found that these interactions came to depend on a unique addition to the cast — endobacteria within the fungi.

NewsMicrofluidic environments alter microbe behaviors, opening potential for engineering social evolution
Microbes are social beings. Much like humans, they communicate and cooperate with each other to solve problems bigger than themselves. In a microbial community, there will even be free riders, and others that police them. So, what if researchers could influence their social evolution to promote certain ...

NewsNew pieces discovered in the puzzle of first life on Earth
Researchers have found evidence dating to around 3.42 billion years ago of an unprecedentedly diverse carbon cycle involving various microorganisms.

NewsVirus that infected the first animals now essential for development of the human embryo
All animals have evolved thanks to the fact that certain viruses infected primitive organisms hundreds of millions of years ago. Researchers now describe the role played by these viruses in a process that is absolutely vital for our development.

NewsComplex green organisms emerged a billion years ago
Using modern gene sequencing data, researchers investigating the evolutionary history of morphological complexity in streptophytes have pinpointed the emergence of multicellularity to almost a billion years ago.

NewsCooler conditions spur bacterial prey species to become the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.

NewsShallow soda lakes show promise as cradles of life on Earth
A new study reports that a shallow “soda lake” in western Canada shows promise for matching the requirements for the emergence of life.

NewsMicrobes reveal Mesolithic tooth decay and gum disease
Members of a hunter-gatherer group that lived in south-western Scandinavia during the Mesolithic era — approximately 10,000 years ago — may have been affected by tooth decay and gum disease, according to a new microbial study.

NewsMicrofossils shed light on the long fossil record of euglenoids
Scientists have shed new light on a group of ‘problematic’ microfossils that have remained a mystery for nearly a century.

NewsStudy uncovers potential origins of life in ancient hot springs
Scientists have found that by mixing hydrogen, bicarbonate, and iron-rich magnetite under conditions mimicking relatively mild hydrothermal vent results in the formation of a spectrum of organic molecules.

NewsEven the oldest eukaryote fossils show dazzling diversity and complexity
Researchers reveal that eukaryotic organisms had already evolved into a diverse array of forms even 1.64 billion years ago.

NewsPhages pay heavy price for environmental intel - but it’s worth it
Phages, the viruses that infect bacteria, will pay a high growth-rate cost to access environmental information that can help them choose which lifecycle to pursue, according to a study. Source: L. F. Lee; J. A. Boezi Bacteriophage gh-1 for Pseudomonas putida. Yigal Meir and colleagues at Ben-Gurion ...

NewsOldest thylakoids in fossil cyanobacteria uncover evolution of photosynthesis
Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered.
