NewsClimate change is redrawing the malaria map in Africa, study finds
A study quantifying climate change’s historical and future impact in sub-Saharan Africa’s children finds that climate change has slightly increased malaria overall. Rising temperatures could increase the malaria risk in southern and East Africa while reducing it where it is most rampant today.

NewsResearch study investigates how maternal viral infections shape lifelong immune health in offspring
A $2.4 million grant will support research that aims to uncover how viral infections during pregnancy reprogram the developing immune system of the fetus, influencing susceptibility to infectious diseases throughout life.

NewsBiofilm clue opens route to anti-infection treatments of the future
A multidisciplinary study has uncovered a critical component in the formation of biofilms, the complex structures used by bacteria to colonise surfaces. The research may have implications for future infection treatments, including for people with cystic fibrosis.

NewsThe hepatitis E virus cannot infect mice - and here’s why
It has long been known that the hepatitis E virus cannot establish an infection in mice, but the reasons were unknown. Scientists have therefore systematically examined the replication cycle of the virus in liver cell cultures of mice.

NewsResearchers propose PIEM concept to reshape microbiome research
A new review introduces a new concept—Persistent Intracellular Extraintestinal Microbes (PIEMs)—that extends microbiome research from body surfaces into internal tissues.

NewsNIH grants $2.8M to develop tools for study of mosquito-microbe interactions
Researchers will use the funding to develop new tools to investigate the genetics underpinning the relationships between mosquitoes and various microbes.

NewsDeadly superbug CR-hvKP: new framework says ‘watch virulence, not just resistance genes’
Carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP) represents one of the most alarming evolutionary developments in modern infectious diseases—a “superbug” that combines high-level antibiotic resistance with enhanced virulence.

NewsLorMe: a unified framework for standardized microbiome analysis
An open-source R framework is designed to provide a unified approach for standardized microbiome analysis. The analytical platform enables the transition from raw microbiome data processing to publication-ready visualization through a streamlined workflow.

NewsNew antimicrobials could help tackle deadly drug-resistant infections
Scientists have developed a promising new way to create safer and more effective treatments for life-threatening fungal infections. Using genome mining, they identified bacterial species capable of producing new, undiscovered antifungals.

NewsElephant vaccine shows first signs of protection against deadly virus
Scientists have published the first peer-reviewed evidence that an experimental mRNA vaccine may help protect young Asian elephants from elephant endotheliotropic herpesvirus, one of the deadliest diseases facing the species.

NewsTire microplastics may accelerate the spread of antibiotic resistance in cities
A new perspective article suggests that tire microplastics could create environmental hotspots that help antibiotic resistance genes persist, move between bacteria, and spread through cities.

NewsYour gut can get jet lag too
Researchers say post-travel symptoms such as fatigue, sleep disturbances, low energy levels, and digestive issues may be caused by more than just classic jet lag. Evidence suggests that time zone changes also affect the trillions of bacteria living in our intestines.

NewsTissue-resident immune cells defend human lungs from viral, bacterial, and fungal infections
A study shows that human lung tissue serves as a “reservoir” for a large number of tissue-resident memory T cells.. These cells stand ready to combat a surprising range of viruses, bacteria, and even deadly fungal pathogens.

NewsStudy shows targeted school closures can improve pandemic response
New research shows that school closures during a pandemic outbreak are most effective when they are carefully targeted. The study demonstrates that the right strategy depends on which age groups are driving transmission at different stages of an outbreak.

NewsNew discoveries on genes involved in lysine biosynthesis and fungal virulence in Cryptococcus neoformans
A new study suggests that disrupting the lysine biosynthesis pathway represents a promising avenue for drug development against Cryptococcus neoformans, a fatal fungal meningitis pathogen.

NewsNanotube connections between social amoebae
Scientists studying the social amoeba Dictyostelium discoideum found that, in addition to signaling molecules drifting from cell to cell freely or inside membrane vesicles, the amoebae also create tunneling nanotubes that physically connect the membranes of cells.

NewsRemdesivir for COVID-19 linked to better outcomes for adult kidney transplant recipients
Adults with kidney transplants who were treated for COVID-19 with the antiviral remdesivir within a week of diagnosis were less likely than kidney transplant recipients who did not receive the antiviral to experience cardiovascular or kidney problems up to a year later.

NewsNew blood test for tuberculosis could reduce the spread of this top global infectious-disease killer
A new study found that a simple blood test could accurately identify tuberculosis (TB) — a leading cause of death worldwide — among patients with varying degrees of exposure to the disease.

NewsDespite progress towards eliminating hepatitis in Europe, gaps in prevention measures keep 2030 targets out of reach
Viral hepatitis remains a significant public health challenge across Europe but childhood vaccination against hepatitis B and provision of harm reduction services show results.

NewsCaterpillar that attacks soybeans and cotton harbors fungi that can degrade polystyrene
A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton, and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as Styrofoam.
