NewsExpanding uses for bioengineered bacterial spores
Fused to the outer layer of bacterial spores, things like enzymes, biosensors, and drugs are easily stored under even extreme conditions.
-
NewsFrog protein could become first antidote to deadly red tide toxin
Red tide algal blooms produce one of the most potent neurotoxins known: saxitoxin, or STX. Researchers have found that a protein called saxiphilin can neutralize saxitoxin in mice, preventing and even reversing otherwise lethal poisoning.
-
NewsHow is climate change affecting waterborne diseases?
Researchers find bacteria, viruses and parasites respond differently to climate change, highlighting the need for pathogen-specific public health strategies.
-
NewsResearchers to tackle overlooked tropical disease
Two researchers are teaming up to build foundational knowledge concerning leishmaniasis, a common, but neglected protozoan parasitic disease. The project combines research into the cell biology of membrane repair with parasitology knowledge.

NewsNovel antifungal drug shows promise in some patients with Valley Fever
A study found that olorofim, a first-in-class orotomide antifungal agent, showed efficacy in patients with disseminated coccidioidomycosis (DCM), a rare complication of Valley Fever where the fungus spreads from the lungs to other parts of the body.
-
NewsAntivaccine legislation is rising rapidly in US states, driven primarily by GOP push
A new study revealed that Republican lawmakers were responsible for 86 per cent of antivaccine bills introduced across state legislatures after the onset of the COVID-19 pandemic, raising concerns about public health.
-
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.
-
NewsHow an influx of salt may affect microbial ecosystems
Scientists find that as sea levels rise and saltwater seeps into freshwater, stressed aquatic populations may retain overall growth even as diversity declines.
-
NewsCyanobacterial toxins can be inhaled
Research on Southwest Florida cyanobacterial blooms shows that the toxins they produce are aerosolized, potentially being inhaled by people far from contaminated water bodies.
-
NewsHuman activities compromise coral health and resilience
Researchers discovered that 25 contaminants from agricultural, industrial, and pharmaceutical sources accumulated in the soft tissues of coral around Maui, Hawai‘i.

NewsNovel pathway suggests gut microbiome could be harnessed to lower blood pressure
The gut microbiome could potentially be harnessed to help lower blood pressure, according to a new study that identifies a previously unknown gut microbiota-bile acid signaling pathway targeting hypertension.
-
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.
-
NewsScientists find hidden individuality in viral infections
An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.
-
NewsScientists receive DOW funding for fungal biotechnology research
Scientists have been awarded funding to develop new tools permitting high-throughput analysis of fungal genes. The grant focuses on species of Candida, which can contaminate and sometimes cause operational issues in DOW systems like aircraft fuel systems, vehicles, and electronics.
-
NewsAt-home, lab-quality HIV tests awarded $1.3 million for development
A new two-year, $1.3 million award will help researchers advance a proof-of-concept work toward commercialization of at-home HIV tests sensitive enough for early diagnosis comparable to—or exceeding—lab standards.
-
NewsResearch team receives $10 million NIH grant to study how animals fight infection
Researchers have built a collection of living cells from over 100 animal species to explore innate immune diversity. They have received a 5-year, $10 million grant to utilize this ‘cellular zoo’ to determine how diverse animals recognize and fight virus infections.
-
NewsResearchers link gut microbe to cancer-fighting immune response
A new study is the first to show metabolites produced by certain bacteria in the gut can positively impact the body’s immune response to cancer.
-
NewsEmerging tick-borne virus raises concern
A study shows how a family of tick-borne viruses known as orthonairoviruses can evade immune defenses, offering important insights into emerging infectious disease threats and the potential pandemic risk posed by these viruses.
-
NewsThe family tree of viruses just grew – and it paves the way for a new approach to agricultural research
Researchers have discovered that a group of viruses known to infect an agriculturally important plant pathogen has remained genetically stable for an astonishing four decades. The work also led to the classification and naming of the group of phages.

NewsSix years of drought reshape soil microbiomes in tallgrass prairie, study finds
A new study tracking soil microbial communities across six years of experimental drought in a tallgrass prairie finds that prolonged water stress diminishes biodiversity, pushing communities toward less predictable, harder-to-reverse configurations.
