Australian researchers report that a rabies virus protein changes shape and binds RNA to access liquid-like cellular compartments, offering a unifying explanation for how the virus exerts broad control with few genes. The work, published October 29, 2025, in Nature Communications, could inform future antivirals and vaccines, the team says.
Researchers in Bangladesh have identified a bat-borne virus, Pteropine orthoreovirus, in five patients initially suspected of Nipah virus infection. All patients had recently consumed raw date palm sap, a known transmission route for bat-related diseases. The discovery highlights the need for broader surveillance of emerging zoonotic threats.

Scientists have discovered that the body's rapid response in nasal cells largely determines whether a rhinovirus infection leads to a mild cold or more severe symptoms. Using lab-grown human nasal tissue, researchers showed how interferons coordinate defenses to contain the virus early. The findings, published January 19 in Cell Press Blue, emphasize the role of host responses over viral traits alone.
