NewsLifestyle, diet, and clinical factors shape the gut microbiome in cancer patients
Lifestyle factors, such as physical activity and dietary modifications can beneficially modulate the gut microbiome of cancer patients - however their effects are often shaped by non-modifiable variables.

NewsTibet’s thawing lakes accelerate greenhouse gas release
Lakes on the Tibetan Plateau are undergoing a dramatic transformation; once stable carbon sinks, they are rapidly becoming significant sources of greenhouse gases due to climate warming.

NewsStick-on gel offers new way to treat and monitor plants
Scientists have developed an adhesive gel that can be loaded with substances, such as small molecule drugs or nanoparticles, and applied directly onto a plant to deliver those materials into its tissues. In tests, a gel loaded with antibiotics cleared a bacterial infection in a plant within about 48 hours.

NewsTick threats in the context of climate change: One Health response strategies in the Middle East and North Africa region
A new study examines the multifaceted dimensions of tick-borne disease management in the MENA region through the lens of the One Health approach. The research synthesizes insights from a symposium that brought together experts to assess current threats and identify pathways forward.

NewsBeyond outbreaks: zoonotic disease prevention at the human–animal interface in China
A study synthesizes evidence on 93 zoonotic diseases currently monitored by China’s public health, agricultural, and forestry sectors, and argues that meaningful risk reduction will require shifting from reactive outbreak response toward earlier prevention at the human–animal–environment interface.

NewsHemp waste biocomposites offer a lower-carbon alternative for packaging and agricultural films
A new study explores how hemp hurd can be converted into microfiber-based biocomposites for packaging films and agricultural mulch films, and shows anaerobic digestion delivers the best environmental outcome for hemp hurd-based bioplastic systems.

NewsKnowledge gaps expose vulnerable populations to tick-borne disease risks in northern China
While awareness of tick biology is relatively high in Northeast China and Inner Mongolia, a new study reveals alarming gaps in public knowledge about preventing tick-borne diseases—with rural residents and high-risk groups paradoxically showing the lowest protective awareness.

NewsScientists pinpoint the changes that happen when gut bacteria invade the bloodstream
Researchers have pinpointed genotypic and phenotypic changes that take place when colonising bacteria in a patient’s gut invade and infect the bloodstream. The team aimed to determine what changes occur within bacteria in a patient’s gut that enable them to become invasive bloodstream pathogens.

CareersFrom microbial processes to biofilm control: our interview with LAM deputy editor Marciane Magnani
We catch up with food microbiologist Professor Marciane Magnani of the Federal University of Paraíba in Brazil who has just been appointed as a Deputy Editor of Letters in Applied Microbiology.

NewsScientists uncover how pathogens switch on their virulence
A research team has uncovered how a key protein switches on the machinery that enables Leptospira pathogens to survive and cause disease. The findings provide new insights into how pathogens regulate their virulence and may open new avenues for therapeutic interventions.

NewsNew study suggests reduced newborn hepatitis B vaccination coverage may increase infant infections
Researchers found that lower vaccination coverage among infants born to unscreened mothers was associated with a substantial increase in HBV infections.

NewsWhere people get their news influences their beliefs about vaccines
People who follow “new right” media outlets are more than twice as likely to be vaccine-hesitant compared to those who never engage with those outlets, a new study finds. Hesitant adults were more likely to rely on non-authoritative sources for health information.

NewsGlobal Virus Network statement on H5N1 vaccine developments
The new vaccine momentum reflects the growing urgency of avian influenza (H5N1) threat and reinforces the need for coordinated global preparedness.

NewsResearchers discover new mosquito-specific viruses
A new study looked at mosquitoes’ immune response to discover many more insect viruses. Researchers hope to someday use the mosquitoes’ own immune system to battle some of the most pervasive and antagonistic human viruses.
-
NewsNew cellular target prevents hepatitis E infection
To replicate, a virus must first enter a host cell. In a recent study, the researchers specifically investigated host cell processes required for successful HEV infection. In doing so, they identified the enzyme PIKfyve as a crucial factor for viral entry.

NewsImmune cells in the nose slow influenza virus
Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may help protect against more severe illness, according to a study that may help guide the development of better influenza vaccines.

NewsAssociation of changes in portal insulin with immunometabolism during and after hepatitis C virus infection
A new study aims to investigate the relationship between insulin, the gut-liver axis, and immunometabolic changes in patients with hepatitis C virus. Lower portal insulin during HCVi is associated with changes consistent with altered pancreatic insulin secretion and decreased hepatic insulin extraction.

NewsSeparating signal from noise: How African biostatisticians are reshaping the fight against malaria
Biostatistics is unlocking smarter malaria solutions, linking parasite diversity, vaccines, and human behaviour to drive more effective prevention and protection.

NewsThe brain–gut health initiative: A pioneering effort in psychiatric research
Researchers analyze brain imaging data, microbiome profiles, and clinical assessments to identify biomarkers for precision mental healthcare. The Brain–Gut Health Initiative is an ongoing long-term clinical study designed to investigate how interactions between the brain and gut microbiome contribute to psychiatric disorders.

NewsScientists highlight the cost of delaying childhood vaccination
Delaying hepatitis B vaccination after birth increases infections among newborns and decreases their survival rates and quality of life. A new study found that the longer the delay, the higher the cost in human life and health care.
