NewsNew DNA analysis approach could transform understanding of disease evolution
By adapting techniques originally used to study ancient DNA from archaeological specimens, researchers were able to recover genetic information from nearly century-old medical samples.

NewsAdvanced imaging reveals new fungus species in 407-million-year-old plant fossil from Scotland
Researchers have identified a new species of ancient symbiotic fungus preserved within a 407-million-year-old plant fossil from Scotland. The discovery provides unprecedented three-dimensional insight into one of the earliest known plant–fungus partnerships.

NewsHow life first got moving: nature’s motor from billions of years ago
Research has cast light on the evolutionary origins of one of nature’s first motors, which developed 3.5 billion to 4 billion years ago to propel bacteria. Scientists have created the most comprehensive picture yet of the evolution of bacterial stators.

NewsScientists uncover global patterns and drivers of orchid mycorrhizal interactions
A global meta-analysis of orchid-fungal associations leads to a general conclusion: an orchid’s fungal community is driven more strongly by its ecophysiology and biogeography than by its phylogeny.

NewsNew study shows invasive Group A Streptococcus outcomes shaped by treatment strategies, not species lineage
Researchers highlight the role of early clindamycin prescription in improving the recovery rate of patients with invasive Group A Streptococcus infections in a study that examined the evolving epidemiology of such infections.

NewsEvolving antibiotic resistance under pressure may lead to personalized treatment
A new study demonstrates the use of an experimental evolution approach to map genetic mutations in Acinetobacter baumannii treated with one of two uncommon antibiotics.

NewsERC Synergy Grant awarded to physicist Michael Lässig and virologist Florian Klein
Researchers have been awarded a Synergy Grant by the European Research Council (ERC) for the project CoEvolve, which investigates the co-evolution of viruses and the immune system.
-
NewsUrban fungi are showing signs of thermal adaptation
A new study finds that common fungal species may be adapting to higher temperatures in warmer sites within cities compared to cooler sites in the same city. The findings could signify that urban fungi could one day evolve into disease-causing pathogens.

NewsAncient viral DNA shapes modern human placentas
Researchers have uncovered how ancient viral DNA controls a gene linked to placenta development and pre-eclampsia, a life-threatening pregnancy disorder. The research could help identify pre-eclampsia risk much earlier.

NewsNew study reveals not all bats carry equal viral risk
A groundbreaking study sheds new light on the relationship between bats and dangerous viruses, showing that contrary to widespread assumptions, not all bats carry viruses with high epidemic potential, only specific groups of species.

NewsHow algae help corals bounce back after bleaching
A $1.1 million project will uncover how reefs regain life-giving algae after suffering from heat stress. The three-year project will use advanced imaging and living experimental systems to learn what’s happening on a cellular level when algae return to bleached reefs.

NewsLichens and drones reveal dinosaur bones
Scientists have found that certain lichen species preferentially colonise exposed dinosaur bones, creating distinctive spectral signatures that can be detected from 30 metres above ground using drones.

NewsUnprecedented decline in marine viruses in the western Mediterranean linked to climate change revealed
Researchers have described a sustained and unprecedented decrease in the abundance of marine viruses in the northwestern Mediterranean over the last two decades. The findingis based on the longest-known time series data on marine viruses to date.

NewsResearchers to investigate moisture-driven Antarctic ice sheet growth during past warm climates
Investigating how increased moisture transport to Antarctica, and under what temperatures and sea ice conditions moisture transport occurs, is required to understand the mechanisms that can lead to increased ice accumulation.

NewsNew study explores ‘legacy effects’ of soil microbes on plants across Kansas
A new study analyzes soils sampled across the state of Kansas to determine the importance of “legacy effects” — or how soils from a specific location are influenced by microbes that have evolved in response to the specific climate at that site for many years.

NewsDNA from Napoleon’s 1812 army identifies the pathogens likely responsible for the army’s demise during their retreat from Russia
Microbial paleogenomicists extracted DNA from the teeth of soldiers from Napoleon’s ill-fated invasion of the Russian Empire and found no trace of typhus. Instead, they identified two pathogens known to cause enteric fever and relapsing fever.

NewsProtection against winter vomiting bug spread with arrival of agriculture
Norovirus clears up after a couple of days, but the protection it provides is short-lived, meaning that the same person can fall repeatedly sick in a short space of time. But some people cannot succumb to the virus, thanks to a particular gene variant whose historical spread has now been traced.

NewsStudy uncovers origins of urban human-biting mosquito, shedding light on uptick in West Nile virus spillover from birds to humans
The research disproves the theory that the mosquito evolved in the London underground by dating the mosquito’s origin back over 1,000 years and identifies the genetic links between bird-biting and human-biting mosquitoes, key to West Nile transmission.

NewsFungi paved the way for life on land hundreds of millions of years earlier than previously thought
After reviewing the evolutionary timeline of fungi, scientists have determined that their origin dates back to between 900 million and 1.4 billion years ago. This means that fungi had already been living on Earth hundreds of millions of years before plants took root on our planet.

NewsDoes floral scent affect insect visitors and bacterial strains on flowers?
A new study reveals that high floral scent chemodiversity is associated with increased pollinator richness but reduced bacterial richness on flowers. The findings led the scientists to propose the ’Filthy Pollinator Hypothesis’.
