TBE cases in Sweden have tripled over ten years despite rising vaccinations. Åke Lundkvist, professor of virology at Uppsala University, suspects the virus may have changed, reducing vaccine effectiveness. Researchers are now analyzing 12,000 ticks to investigate.

Researchers at Caltech have discovered how viruses infect bacteria by disabling a key protein called MurJ, essential for cell wall construction. This mechanism, revealed through high-resolution imaging, suggests a new approach to combating antibiotic-resistant superbugs. The findings highlight convergent evolution in unrelated viruses blocking MurJ similarly.

Scientists at the University of Queensland have captured the first near‑atomic, high‑resolution 3D images of the yellow fever virus, detailing how the surface of the long‑used vaccine strain differs from virulent, disease‑causing strains. The work sheds light on how the virus is recognised by the immune system and could support improved vaccines for yellow fever and related mosquito‑borne diseases.

Researchers at the University of British Columbia have discovered that viral infections in honey bee queens reduce their pheromone production, triggering workers to replace them through a process called supersedure. This finding explains many queen failures faced by beekeepers and suggests synthetic pheromones as a solution to stabilize hives. The study highlights the role of viruses, often spread by varroa mites, in disrupting colony health.
