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.
Rajat and Doron Cohen at Ben‑Gurion University applied a semiclassical tomographic method to link the many‑body spectrum of Bose‑Hubbard condensates with underlying classical phase‑space structures. Their analysis shows that chaotic dynamics only emerge when more than three lattice sites are interconnected, and that stability relies on sizable islands of regular motion that grow with the boson count. As the system approaches the Gross‑Pitaevskii mean‑field limit, chaotic fluctuations diminish, revealing a pathway from quantum chaos to ordered behavior. The work combines Bogoliubov local analysis with global phase‑space inspection to map ergodicity and localisation far from equilibrium.
Chinese researchers aboard the China Space Station have completed the first in‑orbit quantum test of the Weak Equivalence Principle using a dual‑species rubidium atom interferometer.
