NewsWhat makes hantaviruses jump from rodents to humans?
Why do some hantaviruses jump from rodents to humans while others remain largely confined to wildlife? A new study will combine viral genetics, climate data and wildlife ecology to uncover the conditions that drive spillover and help identify where future outbreaks are most likely to emerge.

NewsWeather and poultry litter shape E. coli survival in onion fields
How long can E.coli survive in the soil beneath an onion crop? A two-year field study suggests the answer depends not only on the type of poultry-based fertiliser used, but also on weather conditions such as humidity, rain, temperature and wind. The findings could help growers and regulators better assess food safety risks as extreme weather becomes more common.

NewsWealth and health aren’t the only indicators of national happiness – there are also cats. And their parasites!
National happiness is influenced by complex relationships beyond basic economic factors, according to a study that finds that cats and their parasites are strongly correlated with both positive and negative happiness scores worldwide.

NewsResearchers warn eye infections can cause preventable vision loss
Rising rates of infectious eye diseases are increasing the risk of preventable sight loss, with researchers warning that delayed diagnosis can have lasting consequences. New reviews highlight the importance of recognising symptoms such as blurred vision, floaters and sudden visual changes early, when treatment is most effective.

NewsAnti-cancer molecules show promise in the fight against malaria
Molecules known for their anti-cancer activity have proven effective in combating Plasmodium falciparum, the parasite that causes malaria. Researchers also investigated how differences in the structure of these molecules affect their impact on the parasites.

NewsThe Andes were supposed to stop this cacao killer - they didn’t
Black pod disease destroys up to a quarter of the world’s cacao every year. A study provides the first comprehensive portrait of Phytophthora palmivora’s genetic structure in Colombia. Researchers genotyped and virulence-tested 73 isolates gathered from 48 locations across the country’s three main cacao-growing regions.

NewsA shorter, better-tolerated treatment for chagas disease is possible
A 30-day course of benznidazole taken once a day could offer people with chronic Trypanosoma cruzi infection a safer and more practical option than the current standard treatment, taken twice a day for 60 days.

NewsFirst-of-its-kind preventative phage therapy provides promising results
The mammalian gut microbiome is teeming with a delicate balance of bacteria and the phages that keep them in check. What if the phages in the gut could prepare for an orally ingested pathogen and strike it down as it enters the gut, negating the need for a battle?

OpinionHow Puerto Rico’s first microbiome research center can reshape global science collaboration
AMI’s Global Ambassador for the Americas, Dr. Filipa Godoy-Vitorino, Chair of the Department of Microbiology at the University of Puerto Rico, reveals why she is spearheading the planned Puerto Rico Center for Microbiome Sciences (PR-CMS)—the first of its kind in the region.

NewsThe body doesn’t just absorb a plant-based diet—it adapts to one, new review finds
A new review of plant-based diets concludes that the body actively adapts to sustained dietary change, absorbing iron more efficiently, synthesizing more of its own creatine and carnosine, using protein more economically, and remodeling gut bacteria to better ferment fiber.

NewsHow the Chagas disease parasite ‘activates’ its form capable of infecting mammals
A new study helps determine how Trypanosoma cruzi manipulates its own RNA to alter protein production and invade the host, which could lead to new therapeutic approaches against Chagas disease.

NewsSoil bacteria protect wheat from pathogenic fungus
New research shows that, when inoculated into the soil, bacterial species can alter the soil microbiome and protected plants from a fungus that causes root rot.

NewsTolkien-inspired coral among the stars: New species discovered on Costa Rica’s deep-sea seamounts
Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification.

OpinionWhose culture is it? Rethinking the study of traditional fermented food microbiomes
When microbiologists study traditional fermented foods, are we simply documenting natural biodiversity, or are we also accessing a form of cultural heritage, asks Tara Spencer-Drakes, PhD.

NewsNew vaccine strategy protects against chikungunya and could become a platform for combating other diseases
Researchers created a genetically modified version of the Chikungunya virus that replicates only once, yet still trains the immune system to defend itself without causing disease.

NewsAmazonian ‘zombie’ fungus harbors a hidden stage inside forest mosses, new study reveals
Researchers have found evidence that the “zombie-ant” fungus, globally known for controlling ant behavior and forcing infected ants to bite onto plants before dying, also lives hidden inside mosses in the Amazon rainforest.

NewsStudy detects, for the first time in Brazil, bacteria that cause a serious disease in farmed fish
Columnaris disease pathogens, which were previously only found in Asia and the United States, were identified in samples from São Paulo, Minas Gerais, and Paraná. This finding underscores the need for epidemiological surveillance and new vaccines.
