NewsInactive H5N1 influenza virus in pasteurized milk poses minimal health risks
Proteins and genetic material from H5N1 influenza viruses have been found in pasteurized milk in the United States, but a study shows those inactive viral pieces represent little to no health risk. H5N1-contaminated milk that was pasteurized did not significantly affect the immune system.

NewsNew mechanisms for bacterial motility and DNA transfer between bacteria decoded
Scientists have discovered a new family of signaling proteins, widespread in the bacterial kingdom and contributing to regulating bacterial motility and DNA uptake mechanisms.

NewsGlobal Virus Network launches multi-country mpox diagnostic evaluation to close global preparedness gaps
The Global Virus Network has initiated one of the first coordinated, multi-country evaluations of rapid point-of-care mpox diagnostics, a critical step to prevent resurgence and ensure the world is better prepared for future epidemics.

NewsNew study supports gene-tailored radiation doses to treat HPV+ throat cancer
Genetic testing can identify patients with HPV-positive throat cancer who may benefit from lower radiation doses, according to a new study that builds on a growing body of evidence that radiation treatment can be personalized using tumor genomics.

NewsDespite increase in U.S. cases, worry about West Nile virus remains low
Despite this season’s growing number of cases, relatively few Americans worry about becoming infected by West Nile or by dengue fever, another mosquito-borne illness, according to a survey of nearly 1,700 U.S. adults.

NewsMeta-analysis: COVID-19 vaccination during pregnancy is safe and beneficial for mother and infant
Vaccination is associated with better neonatal outcomes without added maternal risk, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition.

NewsMilk matters: How donor human milk storage affects preemie gut health
A study reveals that shorter storage durations of donor human milk are linked to reduced gastrointestinal complicatoins in premature infants, including necrotizing enterocolitis. These findings suggest that minimizing milk storage time may help to preserve protective properties crucial for preterm gut health.

NewsIn pregnant mice with severe flu, harmful molecules can breach fetal barriers
A new study shows, for the first time, that severe flu infection in pregnant mice leads to a breakdown in placental and brain barriers, leading to the accumulation of potentially harmful molecules in the fetal brain. Fibrinogen can pass into developing fetal brains.

NewsHeadspace invaders: How mosquito-borne viruses breach the brain’s defenses
Using a stem cell-based model of the human blood-brain barrier, researchers compared two closely related Sindbis virus strains — one brain-invading and one not — and found that small changes in viral surface proteins called glycoproteins dictate whether the virus can cross.

NewsKey to the riddle of sleep may be linked to bacteria
New research suggests a new paradigm in understanding sleep, demonstrating that a substance in the mesh-like walls of bacteria, known as peptidoglycan, is naturally present in the brains of mice and closely aligned with the sleep cycle.

NewsTrojan horse: Amoebae as carriers for human Norovirus and Adenovirus
A new study reveals that common waterborne amoebae can ingest and protect human viruses, extending their environmental persistence. Human norovirus and human adenovirus can enter and persist within FLA.

NewsStudy models how human behavior, lockdowns and restrictions shaped COVID’s spread
Researchers employed computer modeling and large datasets to better understand how COVID-19 was transmitted in one community in South Africa during the course of the worldwide pandemic.

NewsNew study finds dried blood spot test reliably detects congenital CMV at birth
New research confirms that testing for congenital cytomegalovirus (cCMV) at birth using the routinely collected dried blood spot (DBS) is a reliable and effective method to identify newborns at risk for long-term developmental challenges.

NewsStudy reveals how tick-borne encephalitis virus enters cells
The protein on human cells that tick-borne encephalitis virus (TBEV) uses for infection has now been identified—a major step toward understanding how TBEV causes neurological disease and for developing antiviral drugs.
