NewsNipah virus hijacks host protein NSUN2 to fuel replication
Researchers have decoded a critical survival strategy of the deadly Nipah virus (NiV), identifying a key host protein hijacked by the pathogen and translating this discovery into a promising new treatment approach.

NewsMillions-of-years-old insect symbioses are surprisingly fragile
An introduced bacterium displaces the sawtoothed grain beetle’s symbiotic partner, leading to the complete collapse of a previously stable symbiosis within a few generations.

NewsOregano, rosemary and ‘time’: Long-term swine study shows natural-compound benefits
In a rare long-term public study that compared the effects of phytochemicals from rosemary and oregano with antibiotic growth promoters, animal scientists found that the natural agents given to weaned pigs supported favorable gut health and growth performance later in their lives.

NewsScientists solve 40-year-old biological mystery behind sleeping sickness
Scientists have cracked a 40-year-old biological cold case by revealing how the parasite that causes sleeping sickness stays one step ahead of the human immune system.

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.

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.

NewsResearchers reveal m6A epigenetic modification controls arbovirus infection and transmission between vertebrates and mosquitoes
Researchers reveal that N6-methyladenosine (m6A) epigenetic modifications in mosquito-borne flaviviruses (MBFs) enhance viral propagation in vertebrates and thus increase transmission from vertebrates to mosquitoes.

NewsDiet determines the bacteria present in microbial gardens cultivated by ants
Researchers studying leafcutter ants have demonstrated how bacteria in the colonies respond to different diets provided by ants to the fungi they cultivate. The study paves the way for a better understanding of how colonies function and may lead to the discovery of new molecules for biotechnological use.

NewsBird flu risk to Danish cattle – new tool can warn farmers before infection spreads
Researchers have developed a tool that can predict where and when the risk of infection is highest. The tool is based on infection data from the U.S. outbreaks and adapted to a Danish context.

NewsTurning agricultural waste into smarter livestock nutrition tools - and an alternative to antibiotics
A new study has found that biochar made from agricultural waste such as chestnut shells and vine prunings could help deliver beneficial compounds more effectively in animal feed, offering a promising alternative to antibiotics in livestock production.

NewsClimate change is fueling disease outbreaks
Researchers analyzed the connection between a cyclone in Peru and a massive outbreak of dengue fever, a mosquito-borne viral disease that can cause fever, rash, and life-threatening symptoms like hemorrhage and shock. Their findings reveal that warmer, wetter weather linked to climate change is making disease epidemics more likely.

NewsWhat factors influence likelihood and severity of Ebola outbreaks?
Two new papers looked at factors that contribute to how Ebola outbreaks begin and how severe they become. This Q&A looks at how the results could inform public health interventions to prevent pathogen emergence or slow the spread of Ebola and other infectious diseases.

NewsTicks carrying more than one pathogen are on the rise in US Northeast
Tick-borne diseases are on the rise in the northeastern US, with many ticks carrying more than one pathogen. Most commonly found together were Borrelia burgdorferi and Babesia microti. Co-infection with these two pathogens was more frequent than expected, approaching 11% by the end of the study.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

NewsArtificial feeding platform transforms study of ticks and their diseases
The world’s first lab-based tick feeding system for bush ticks has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces the need for animal experiments in tick studies, facilitating more ethical, reproducible research.

NewsNew study reveals how hygienic honey bees show unique advantages in fighting infectious pathogens in adult bees
For the first time, research shows that a key social trait in honey bees is linked to measurable physiological advantages that can improve colony survival. The study uncovers how hygienic honey bee colonies mount stronger individual immune defenses against Nosema ceranae.

NewsPig farm ammonia pollution may indirectly accelerate climate warming, new study finds
A new study shows that ammonia released from intensive livestock farms can significantly increase nearby soil emissions of nitrous oxide, a powerful greenhouse gas that contributes to climate change and ozone depletion.

NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsBig and small dogs both impact indoor air quality - just differently
An initial study reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.

NewsImaging technique is step towards needed treatments for hantaviruses in new molecular ma
Researchers have produced a detailed blueprint, the highest resolution yet, for a protein complex the Andes virus uses to infect host cells. The new detailed structural information enabled the researchers to produce a vaccine candidate that caused mice to produce neutralizing antibodies against the Andes virus.
