Scientists solve the mystery of a brain “switch” that can trigger weight loss in opposite ways
Activating the GIP receptor in the brainstem reduced appetite in mice, while blocking it in the hypothalamus enhanced fullness signals through different mechanisms. The finding explains why distinct obesity drugs targeting the same receptor produce similar weight loss results and suggests combining GIP treatments with GLP-1 drugs could strengthen effects.

Bacteriophages, tiny viruses that infect bacteria, could help treat antibiotic-resistant infections. Scientists are using artificial intelligence to understand how these viruses function at a molecular level.
How healthier farm animals can cut greenhouse gas emissions
Improved animal health on farms reduces wasted resources from miscarriages and other reproductive losses, lowering greenhouse gas emissions from feed production and land use. Healthier dairy cows prevent resource losses including feed already grown, water consumed, and emissions released during pregnancies that do not result in milk production or viable offspring.
Topical clove oil for canine sarcoptic mange promises faster, plant-based treatment
Topical clove oil treats canine sarcoptic mange, a mite-caused skin condition that can progress to bleeding sores and death if untreated. The plant-based treatment offers an alternative to conventional therapies for this contagious, zoonotic condition caused by Sarcoptes scabiei microscopic mites.
