NewsClimate change may produce ‘fast-food’ phytoplankton
Scientists report that as sea surface temperatures rise over the next century, phytoplankton in polar regions will adapt to be less rich in proteins, heavier in carbohydrates, and lower in nutrients overall.

NewsGlobal Virus Network launches expanded “Global Guardians for Pandemic Preparedness” program for Florida high school students
The Global Virus Network (GVN) announced the launch of its expanded Global Guardians for Pandemic Preparedness initiative, with applications now open for high school students across the state of Florida.

NewsThe tumor microbiota: A new frontier in cancer biology
A new study synthesizes evidence from different types of tumors, particularly those characterized by low microbial biomass, where conclusions require particularly rigorous validation. By outlining a roadmap of experimental and analytical standards, this work provides the basis for more robust research.

NewsScientists develop therapeutic, nasally delivered DNA vaccine for tuberculosis
Research shows the vaccine — in combination with drug therapy — accelerated a relapse-free TB cure in mice, improved activity of a drug-resistant TB regimen and stimulated immune responses in nonhuman primates.

NewsUnexpected potential bacterial symbiosis found in fungus that causes angular leaf spot
Scientists have uncovered an unexpected microbial relationship that could help explain differences in the severity of a major disease affecting common beans. The discovery sheds light on how the pathogen evolves and may point to new strategies.

NewsMissing gut bacteria may prevent some people with celiac disease from fully benefiting from high-fiber supplements or diets
Many people with celiac disease are advised to eat more fibre to support digestion and manage symptoms, either through diet or prescribed fibre supplements. New research shows that the benefits of that fibre may depend on whether the right bacteria are present in the gut to break it down.

NewsGetting a glimpse of viral dances in the dark in the Sargasso Sea
In a new study of viral abundance over a short time frame in the Sargasso Sea, researchers found that almost all viruses with cyclical changes in abundance were most active at night – a somewhat surprising find.

NewsResearch cracks genetic code of growing bacterial threat
Scientists have discovered that a fast‑rising strep bacterium comes in more forms than expected, including ones that may lead to life-threatening infections. Streptococcus dysgalactiae subspecies equisimilis (SDSE) was originally considered rare and was believed to mostly infect people who already had other health issues.

NewsStopping algae blooms with bacteria-busting buoys
Algae blooms make a pond’s surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. So, a team reporting in ACS ES&T Water has designed a “set it and forget it” system for distributing algaecide using ...

NewsCopper-loaded starch nanoparticles can target bacteria in microbial communities
Researchers have developed copper-loaded starch nanoparticles that can be broken down by specific bacteria to release antibacterial copper molecules. They hope that these nanoparticles can be used to target biofilms, which account for 50-70% of healthcare-associated infections.

NewsNew vaccine strategy could help extend immunity against evolving viruses
Researchers have identified a possible way to make longer lasting vaccines for respiratory viruses like influenza and the coronavirus that causes COVID-19.

NewsVitamin D linked to immune response to gut microbiome in inflammatory bowel disease
Vitamin D supplementation may help shape how the immune system responds to gut bacteria in people with inflammatory bowel disease (IBD), according to a new study.

NewsWhen algae stop growing, bacteria start swarming
A new study describes how a recently identified species of marine bacteria targets diatoms based on growth phase and nutrient availability.

NewsStudy reveals how a live bacterial therapy reshapes the vaginal microbiome and identifies predictors of treatment success
A new study provides the most detailed picture yet of how a promising bacterial therapy works to prevent recurrent bacterial vaginosis (BV) and why it works better for some women than others.

NewsScientists studying bird flu in the air to protect people and agricultural operations
New research will investigate how nonthermal plasmas can render aerosols containing the virus that causes bird flu incapable of infecting humans and livestock. The approach exposes air to strong electric fields, temporarily creating free electrical charges that damage viruses.

NewsAging lung cells could be why COVID and flu are so dangerous to the elderly
Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers.

NewsFiber in whole wheat foods protects against gut inflammation in mice, study finds
Enriching the diet with wheat fiber protects mice against intestinal inflammation, according to a study. The finding helps explain why incidence of inflammatory bowel disease (IBD) has increased, and suggests eating whole wheat foods may reduce one’s risk of developing it.

NewsScientists identify new Fusarium species behind wheat disease outbreak in Ethiopia
New research provides new insights into the severe 2022 outbreak of Fusarium head blight in Ethiopia and identifies emerging fungal pathogens that could have broader implications for global wheat production.

NewsRNA-guided CRISPR system activates gene expression
In back-to-back studies, researchers report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing systems that merely find and cut DNA.

NewsFirst Chagas disease conference on US soil highlights a turning point in national awareness
For the first time, a conference dedicated to Chagas disease research will be held on U.S. soil, marking a significant and symbolic moment for researchers, clinicians and public health leaders working to boost awareness of the disease in this country.
