We isolated Japanese encephalitis virus (JEV) from brain samples of 2 seals with lethal encephalitis at Weihai Aquarium, Weihai, China, in 2017. We confirmed our findings by immunohistochemical staining and electron microscopy. Phylogenetic analysis showed this virus was genotype I. Our findings suggest that JEV might disseminate though infected zoo animals.

Record-breaking temperatures are nothing new for Norwegian glaciers. If temperatures become warmer, more glaciers may disappear.

According to the Canadian Association of Professional Apiculturists, the most frequently cited causes of bee mortality were weather, starvation, poor queens and weak colonies in the fall.
