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 at McGill University have developed a technique using severed mosquito proboscises as ultra-fine nozzles for 3D printing, enabling the creation of structures as thin as 20 micrometres. This innovation, dubbed 3D necroprinting, addresses the limitations of commercial nozzles and could aid in producing replacement tissues and organs. The approach draws inspiration from nature to achieve affordable, precise bioprinting.
