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.
Researchers introduced FAST‑CRISPR, a lipid‑silica hybrid nanoparticle that fuses directly with cell membranes to deliver CRISPR/Cas9 ribonucleoproteins. By combining a 1:1 weight ratio of cationic DOTAP and ionizable DODMA lipids with large‑pore silica cores, the platform achieves high RNP loading and rapid cytosolic release. In mouse xenograft models, FAST‑CRISPR induced targeted DNA breaks, triggered cancer‑cell apoptosis, and markedly reduced tumor growth without observable systemic toxicity. The study positions this non‑viral system as a scalable alternative for therapeutic genome editing.
Researchers have converted common red brick into a Fe2P‑based cocatalyst sheet that serves as a scaffold for semiconductor particles, creating monolithic photocatalysts for solar water splitting.
