NewsHow bats tolerate viruses: study sheds light on one of nature’s biggest immune mysteries
Researchers have found that the world’s largest family of bats has two distinct copies of the genes that produce antibodies, the specialized proteins that help the immune system recognize and fight infections. Every other known mammal has only one such set.

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.

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.

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.

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.

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.

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.

NewsStudy reveals dengue virus can infect immune cells meant to fight disease
Researchers have discovered that dengue virus can infect and replicate inside memory B cells, immune cells traditionally understood to help protect the body from infection. It’s a previously unrecognized way the virus may evade immune defenses.
-
NewsNew drug could contribute to stopping measles outbreaks
A new oral antiviral drug candidate administered either before or after direct contact or airborne exposure to canine distemper virus, which causes measles-like disease in ferrets, blocks transmission of the virus and reduces clinical symptoms.
-
NewsThe Great Barrier Reef has a microbiome too
A study documents over 800,000 microbial genomes, identifying over 500 new bacterial species and over 300,000 distinct viruses in the waters of the Great Barrier Reef.

NewsHow the encephalomyocarditis virus hijacks host protein machinery
Researchers have used cryo-electron microscopy (cryo-EM) to decode how the encephalomyocarditis virus (EMCV) IRES hijacks the host’s protein synthesis machinery.
-
NewsIs the licensed Zaire ebolavirus vaccine suitable to combat the current Bundibugyo ebolavirus outbreak?
Researchers provide evidence of possible cross-protection through an already licensed Zaire ebolavirus vaccine.

NewsNew open-access database maps pathogens and antibiotic resistance risks in coastal waters
A new global database brings together information on disease-causing microorganisms, antibiotic resistance genes, and virulence factors in coastal waters, offering a practical tool for assessing biological risks in estuaries and other nearshore environments.
-
NewsScientists map how the flu virus rewires the human cell from the inside
Researchers have gained new insights into how the influenza A virus reprograms cellular machinery by tracking molecular interactions directly inside infected cells.
-
NewsCOVID-19 vaccines remain effective despite helminth-induced immune modulation
In a preclinical study, researchers have found that mRNA- and protein-based SARS-CoV-2 vaccines effectively protected Schistosoma-infected mice against the virus, despite the mice’s distinct immune response profiles.

NewsNew Piem concept proposed: Reshaping human microbiome research and opening a new chapter in precision medicine
Researchers systematically proposed the novel concept of “Persistent Intracellular Extraintestinal Microbes” (PIEM). This expands the scope of microbiome research from external surfaces to the body’s interior.

NewsHow is climate change affecting waterborne diseases?
Researchers find bacteria, viruses and parasites respond differently to climate change, highlighting the need for pathogen-specific public health strategies.
