NewsNovel antibody platform tackles viral mutations
Scientists have developed an innovative antibody platform aimed at tackling one of the greatest challenges in treating rapidly evolving viruses like SARS-CoV-2: their ability to mutate and evade existing vaccines and therapies.

NewsMajor antimicrobial power boost as phages form into surprising flower shapes
Researchers treated bacteria-eating viruses so they could be viewed alive under an electron microscope and coaxed them to join together into flower-like shapes - discovering that this made them 100 times more efficient.

NewsResearchers to deploy fungus to combat devilishly invasive tree-of-heaven
Researchers are examining if a natural fungus that kills the highly invasive tree-of-heaven could be spread to other trees-of-heaven by the spotted lanternfly, in turn reducing populations of this pest insect as well.

NewsLoss of ‘nitrogen fixers’ threatens biodiversity and ecosystems
A new study reveals that increased nitrogen deposition from human activity is reducing the diversity and evolutionary distinctiveness of nitrogen-fixing plants, leading to simplified plant communities with fewer species of nitrogen fixers.

NewsIdentifying the genes that viruses ‘steal’ from ocean microbes
The microbes that cycle nutrients in the ocean don’t do the work on their own – the viruses that infect them also influence the process.

NewsSoil’s secret language: Researchers decode plant-to-fungi communication
Researchers have cracked the code of plant-to-fungi communication, using baker’s yeast to reveal that the plant hormone strigolactone (SL) activates fungal genes and proteins associated with phosphate metabolism, a system that is key to growth.
