How Orthoflaviviruses Hijack Mitochondria to Survive in Mosquitoes

by

According to a recent review published in the journal npj Viruses, researchers have discovered that mosquito-borne orthoflaviviruses drive distinct cellular damage in human hosts while establishing lifelong, non-lethal infections in mosquito vectors. This divergence stems from how these viruses manipulate host mitochondrial dynamics, offering new avenues for targeted antiviral strategies against pathogens like dengue, Zika, … Read more

H5N1 Bird Flu Infections Remain Rare Among Exposed Workers

by

Human infections with highly pathogenic avian influenza A(H5N1) remain rare and mild among exposed poultry workers, according to a cohort study published in the journal Eurosurveillance. Researchers investigating outbreak sites in England between April 2023 and March 2025 found that fewer than 1% of monitored individuals met criteria for infection, even as rising animal spillover … Read more

Ancient Evolution Linked to Severe COVID-19 Risk

by

According to a study published in BMC Biology, researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University have discovered that modern human immune responses bear genetic marks of ancient battles with infectious diseases, while also identifying rare variants linked to severe COVID-19. The findings bridge human evolution and infectious disease. … Read more

Ebola Outbreak Spreads Faster Than Record Worst Year

by

The Ebola outbreak in Congo has killed over 1,000 people, reaching that grim milestone nearly three times faster than the 2014-2016 epidemic, according to data released by Congo’s Ministry of Health. Congo Health Ministry Data Tracks Record-Breaking Viral Spread Data from Congo’s Ministry of Health shows that the current outbreak, declared on May 15, recorded … Read more

Non-Endocytic Transmembrane Delivery for Precision Medicine

by

Non-endocytic transmembrane delivery strategies are emerging to bypass canonical cellular uptake routes, directly addressing the low endosomal escape efficiency that has long hindered the clinical translation of therapeutic biomacromolecules like mRNA and gene-editing tools. According to a review published in Biomedical Analysis, these advanced platforms offer a direct path to the cytosol, potentially reshaping the … Read more

Survey Reveals Widespread Confusion Over Pregnancy Vaccine Guidelines

by

Most U.S. adults remain uncertain about which vaccines are recommended during pregnancy, according to a July 2026 survey by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania. While awareness of seasonal flu shots is highest, fewer than one-third of Americans correctly identify the CDC’s recommendations for Tdap, RSV, or hepatitis B vaccines, … Read more

Key Immune Response Linked to Severe COVID-19 Susceptibility

by

New research published in the journal Cell reveals that severe COVID-19 cases are often linked to a pre-existing immune defect where the body produces autoantibodies that neutralize type I interferons. According to findings from an international team of scientists, these autoantibodies are the result of a mature B-cell response that disables the body’s primary antiviral … Read more
