NewsScientist developing probiotics to combat bovine respiratory disease
A new research project aims to develop probiotics derived from healthy cattle to prevent bovine respiratory disease, which is estimated to be responsible for about 70 to 80 percent of feedlot illnesses, and between 40 and 50 percent of all feedlot deaths in the US.

NewsMigrating birds have stowaway passengers: invasive ticks could spread novel diseases around the world
Ticks have always travelled on migrating birds — but the rising temperatures of the climate crisis mean they may now survive at their destination, and so could the pathogens they carry.

NewsClimate change responsible for 19% of today’s rising dengue burden - but Wolbachia offers hope
Climate change is having a massive global impact on dengue transmission, accounting for 19% of the current dengue burden, with a potential to spark an additional 40%-60% spike by 2050 — and by as much as 150%-200% in some areas.

NewsWashington coast avian flu outbreak devastated Caspian terns, jumped to seals
An epidemiological study found that 56% of a large breeding colony of Caspian terns died from a 2023 outbreak of highly pathogenic avian influenza at Rat Island in Washington state. Since then, no birds have successfully bred on the island.
