NewsMetabolites produced in the intestine play a central role in controlling obesity and diabetes
A study has identified a group of metabolites that travel from the intestine to the liver and then to the heart, where they are pumped throughout the body. These metabolites play an important role in controlling metabolic pathways in the liver and insulin sensitivity.

NewsAcid rain may be training soil bacteria to become more deadly
Acid rain from fossil fuel pollution may be quietly training soil bacteria to become longer-lived, more transmissible, and more deadly, according to a new study that tracks how a notorious foodborne pathogen rapidly evolved under simulated acid deposition.

NewsCuring hepatitis C can rebalance immunity in Indonesians living with HIV
A new study provides the first longitudinal immunological data on HIV/HCV-coinfected individuals in Southeast Asia, underscoring the importance of early hepatitis C treatment to prevent long-term immune and liver complications.

NewsParkinson’s drug offers basis for new hospital bacterium anti-infectives
Researchers have discovered a promising starting point for the development of new active substances against the hospital germ Pseudomonas aeruginosa.

NewsResearchers warn: Climate change could expand habitats for malaria mosquitoes
A new study shows that future climate change could create more favourable conditions for malaria mosquitoes, exposing millions of people across large parts of Africa to more dangerous mosquito bites.

NewsResearch into zoonotic disease risks requires a One Health approach
A new evidence brief, based on a study by the Juno Evidence Alliance conducted in collaboration with CABI’s One Health Hub, has highlighted that a One Health approach is needed in research into zoonotic disease risks around the world.

NewsMichigan cherry farmers find a surprising food safety ally: falcons
By shooing cherry-pecking birds away, kestrels also keep them from contaminating crops with their droppings, a new study shows. Kestrels were associated with a 3-fold reduction in droppings spotted on branches.

NewsExpanding seasonal immunization access could minimize off-season RSV epidemics
Researchers found differences in how respiratory syncytial virus spreads among children in rural versus urban communities and concluded that year-round immunizations would minimize risks of large seasonal outbreaks.

NewsIsland-wide field surveys illuminate land-sea connections in Mo‘orea
A multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and rainfall can be an important mediator for connections between land and lagoon waters.

NewsEarthquakes shake up Yellowstone’s subterranean ecosystems
Researchers chronicled the ecological changes in subsurface microbial communities that took place after a swarm of small earthquakes rattled the Yellowstone Plateau Volcanic Field in 2021.

NewsFestive cheer: Soaked raisins ferment to turn water into wine
Scientists have discovered that soaking sun-dried raisins in water is a successful method of creating wine. It was thought that ancient wine production relied on the natural fermentation process of storing crushed grapes in jars, but Saccharomyces cerevisiae rarely colonizes grape skins.

NewsHospital infections associated with higher risk of dementia
A large-scale meta-analysis shows that adults hospitalized with infections have a significantly higher risk of developing dementia. Among the types of infections studied, sepsis carried the highest risk, followed by pneumonia, urinary tract infections, and skin or soft tissue infections.

NewsIs malaria messaging working? African biostatisticians have the data
New analysis shows malaria messaging works. Using advanced causal methods, researchers found that exposure to prevention messages increases insecticide-treated net use among women and children in Uganda, offering rare causal evidence to guide policy.

NewsStaphylococci compete with other bacteria for biotin in the nasal cavity
A recently published study reveals that competition plays a major role in the nutrient-poor habitat of the human nose. There’s an active contest between S. aureus and nasal commensals for the vitamin biotin, which affects the fitness of S. aureus.

NewsExperimental mRNA therapy shows potential to combat antibiotic-resistant infections
Researchers have reported early success with a novel mRNA-based therapy designed to combat antibiotic-resistant bacteria. In preclinical studies, the therapy slowed bacterial growth, strengthened immune cell activity, and reduced lung tissue damage in models of multidrug-resistant pneumonia.

NewsOceanographers present new conceptual framework to answer age-old question: What happens to carbon as it sinks through the ocean?
New research spanning multiple ocean regions has found upper ocean ecosystem conditions, such as nutrient availability and microbial interactions, play a major role in shaping the composition of carbon-rich particles sinking into the deep ocean.

NewsPesticides and other common chemical pollutants are toxic to our ‘good’ gut bacteria
A large-scale laboratory screening of human-made chemicals has identified 168 chemicals that are toxic to bacteria found in the healthy human gut. These chemicals stifle the growth of gut bacteria thought to be vital for health.

NewsNew study reveals how a common antibiotic disrupts nitrogen cycling and boosts greenhouse gas emissions in estuaries
Antibiotics may have far reaching impacts on wetland chemistry, according to a new study that identifies the bacteria responsible for breaking down the antibiotic sulfamethoxazole and links this process to increased emissions of nitrous oxide, a potent greenhouse gas.
-
NewsMalaria parasites move on right-handed helices
After penetrating the skin, the malaria parasite moves with helical trajectories, almost always turning toward the right. Researchers demonstrated that the pathogen uses these right-handed helices to control its motion as it transitions from one tissue compartment to another.

NewsPrebiotic in diet linked to less impulsivity in gambling rats with traumatic brain injury
Using a prebiotic to influence bacterial activity in the gut after a traumatic brain injury may help reduce impulsive behavior, one of the common symptoms to follow a moderate blow to the head, a new study in rats suggests.
