High‑altitude hypoxia curbs blood‑sugar spikes in mice
A mouse study found that low‑oxygen (hypoxic) conditions cause red blood cells to absorb far more glucose and convert it into a molecule that eases oxygen release, acting as a glucose sink. Mice exposed to 8% oxygen showed markedly smaller blood‑sugar spikes after glucose injections, and the effect persisted after they returned to normal air.
A newly examined Edmontosaurus skull from Montana displays unmistakable Tyrannosaurus rex bite marks. A broken tooth tip lodged in the snout and multiple serrated impressions pinpoint an adult T. rex with a one‑meter skull as the attacker. CT scans reveal the bite was delivered face‑to‑face, likely killing the herbivore before the tyrannosaur stripped flesh, especially from muscle‑rich skull regions. This rare fossil provides concrete evidence that T. rex both hunted and consumed large duck‑billed dinosaurs.
Researchers evaluated an intranasal bovine coronavirus/rotavirus vaccine in a commercial Alberta cow‑cattle operation to determine its effect on pre‑weaning respiratory disease. In a randomized trial of 887 calves, the vaccinated group required treatment for bovine respiratory disease (BRD) in 16 %...
