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 discovered that clemastine fumarate activates lipophagy in oligodendrocyte progenitor cells (OPCs), clearing lipid droplets that impede differentiation. In vitro, the drug enhanced OPC maturation and removed myelin debris, while in a cuprizone‑induced mouse model it restored myelin integrity and reduced lipid accumulation. Molecular analysis showed up‑regulation of autophagy genes BECN1 and decreased p62 expression, linking lipid clearance to remyelination. The work reveals a novel metabolic mechanism for an existing antihistamine, suggesting repurposing potential for multiple sclerosis therapy.
Researchers have created a Janus‑type nanofiber film that couples chiral quasi‑2D perovskite nanosheets with achiral perovskite nanocrystals or dye molecules via efficient energy transfer. This architecture raises the photoluminescence quantum yield of the achiral component by four times and pushes...
The new Functional Variance Hypothesis (FVH) argues that non‑reproductive helpers act primarily as stochastic buffers against rare, high‑lethality environmental crises rather than as growth enhancers. Using a nonlinear persistence model, the authors derive a unique stable optimal helper ratio that...

Researchers fed BALB/c mice diets containing 1 %, 2.5 %, 5 %, or 10 % fructo‑oligosaccharides (FOS) before and during house‑dust‑mite sensitisation. While overall eosinophil recruitment to the lungs was unchanged, FOS dose‑dependently lowered lung Th2 cell frequencies and reduced key type 2 cytokines such...
A new review in Frontiers in Nutrition (published March 24 2026) synthesizes interdisciplinary research on intestinal mucosal barrier injury, integrating perspectives from Traditional Chinese Medicine, nutrition, environmental science, psychology, genetics and food science.
