NewsHow green algae count cell divisions reveals key step needed for multicellular life
Scientists have made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.

NewsRecreation of ancient seawater reveals which nutrients shaped the evolution of early life
Scientists know very little about conditions in the ocean when life first evolved, but new research published in Nature Geoscience has revealed how geological processes controlled which nutrients were available to fuel their development. All life uses nutrients such as zinc and copper to form proteins. The ...

NewsLongstanding mystery of phosphite solved with help of sewage plant
Biologists have discovered a phosphorus-based bacterial metabolism that is both new and ancient, thanks to a calculation from the 1980s, a sewage plant, a new bacterial organism, and a remnant from around 2.5 billion years ago.

News Bacteria-virus arms race provides rare window into rapid and complex evolution
Researchers documenting rapid evolutionary processes in simple laboratory flasks show that intricate ecological networks emerge from simple beginnings that feature repeating patterns of evolutionary development.

NewsNew model shows bacterial chase-and-evade activities can form higher pattern
A new model demonstrates that chasing interactions can induce dynamical patterns in the organization of bacterial species.

NewsAntiviral drug linked to SARS-CoV-2 mutations
Researchers have uncovered a link between an antiviral drug for COVID-19 infections called molnupiravir and a pattern of mutations in the SARS-CoV-2 virus.

NewsAlgae provide clues about 600 million years of plant evolution
Research team led by Göttingen University investigates 10 billion RNA snippets to identify ’hub genes’.

NewsSome hosts have an ‘evolutionary addiction’ to their microbiome
Microbes might not actually be helping their hosts; instead, microbe-free hosts might malfunction because they have evolved an addiction to their microbes, says one evolutionary ecologist.

NewsShell-building strategies could be key in climate models
A scientist investigating how single-celled organisms discovered how to build a ‘shell’ around their single cell says it could help predict how the calcium balance in the oceans will change under the influence of the changing climate.

NewsHost-to-host microbe transmission impacts bacterial evolution in the gut
A new study uncovers a significant role for bacterial transmission across hosts in shaping the adaptive evolution of new strains that colonize gut microbiomes.

NewsScientists reveal how microalgae cope with environmental challenges
A study has shed new light on the intricate relationship between competition, evolution, and ecological communities in microalgae.

NewsMulticellular life on Earth ‘didn’t arise as described in textbooks’
Oxygen didn’t catalyze the swift blossoming of Earth’s first multicellular organisms, a new study says, defying a 70-year-old assumption about what caused an explosion of oceanic fauna hundreds of millions of years ago.

NewsArtificial cells show that ‘life finds a way’
Scientists studying a synthetically constructed minimal cell that has been stripped of all but its essential genes have found it can evolve just as fast as a normal cell.

NewsComplex life descended from common Asgardian ancestor
Researchers analyzing the genomes of hundreds of different archaea have discovered that eukaryotes trace their roots to a common Asgard archaean ancestor.

NewsMapping evolution of E. coli virulence factor offers refined drug target
Researchers have presented evidence that targeting the K1 capsule can be used as the basis of treatment, paving the way to prevent serious E. coli infections.

NewsAncestral mitoviruses discovered in mycorrhizal fungi
A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.
-
NewsProchlorococcus ancestors rafted out to sea on chitin particles
Scientists propose that ancestors of Prochlorococcus hitched a ride on passing exoskeleton particles, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.

NewsBacteria evolve antibiotic resistance quickly by rejigging pumps
Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research from the Quadram Institute and University of East Anglia.

NewsAfrican rhinos have retroviruses not found in their cousins
New research reveals that the genomes of African rhinos contain dozens of gammaretroviruses that are absent from the genomes of Asian rhino species, such as the Sumatran and Javan rhino, and the African black rhino has two related groups, one missing from the white rhinos.
