Glucagon plays a key role in regulating blood glucose levels. Here, Liu et al. show that

activation of α-cell Gs signaling promotes the release of glucagon from pancreatic islets and ensures the synthesis of sufficient amounts of glucagon.

Permafrost soils can be substantial sources of nitrous oxide (N₂O) to the atmosphere, but no data exist on the N₂O footprints of permafrost rivers. Here, the authors show that alpine permafrost rivers are unexpectedly small sources of atmospheric N₂O at present.

Therapeutic options for non-small cell lung cancer patients with brain metastases are limited. Here the authors design B7-H3 targeting CAR-T cells engineered to express the chemokine receptor CCR2b, and show improved accumulation in the brain and enhanced anti-tumor activity in preclinical models of lung cancer brain metastases.
