Global winds could explain record rains, tornadoes

A study proposes a common root for record-breaking rainfall and historic tornado outbreaks in the US. Researchers link these events to a rare coupling between polar and subtropical jet streams originating in the western Pacific. This phenomenon, known as a 'superjet,' can carry twice as much energy as typical jet streams.

Infectious fungus, thought to be asexual, isn't

New research reveals that Candida tropicalis can mate sexually, contrary to its long-held reputation as an asexual organism. This discovery may allow the species to evolve faster and develop increased virulence or drug resistance.

Healthy piglets? Not with sulfonamides!

Researchers have discovered that toltrazuril can effectively control coccidiosis in piglets, whereas sulfonamides fail to provide sufficient protection. Toltrazuril treatment has been shown to significantly improve health outcomes and reduce diarrhoea in pigs.
