NewsWhen it comes to brain health, is microbiome science missing much of the world?
For more than two decades, scientists have uncovered remarkable links between the trillions of microbes living in our gut and the health of our brains. What if much of this science is based on studying only a narrow slice of global diversity?

NewsData may reveal the hidden communication of pathogenic fungi
Researchers creating the first comprehensive fungal EV atlas will investigate vesicles produced by fungi belonging to the Candida, Aspergillus and Cryptococcus genera, while also working to standardise the methods used for their isolation and analysis.

NewsConnection between forests and rivers strengthens amphibians’ microbiome and protects them against a lethal fungus
A study indicates that a frog’s resistance to a fungus that has decimated hundreds of amphibian species worldwide is due not only to its genes, but also to the beneficial bacteria living on its skin and to the organization of its surrounding landscape.

NewsBiomaterial made from jackfruit latex is a promising treatment for periodontitis
Researchers have developed a biomaterial containing jackfruit latex, pomegranate peel extract, and simvastatin that shows promising efficacy in treating periodontitis. This chronic inflammatory disease of infectious origin leads to the progressive destruction of the tissues supporting the teeth, resulting in bone resorption and loss of attachment.

FeaturesBottling the extremes: culturing the hidden microbiomes of caves and deserts
Imagine an environment so extreme that most life cannot survive: a pitch-dark cave deep beneath the mountains of Northern Spain, or a hyper-arid desert in Chile where rainfall is virtually non-existent. These are not lifeless wastelands. Beneath cave walls and within the dusty top layer of desert soils, thriving communities of cyanobacteria, green algae, and fungi quietly engineer their ecosystems: fixing carbon, weathering rock, and cycling nutrients in conditions that would defeat most organisms on Earth.
