Postprandial Glucagon Action in the Human Brain
Diabetes, Obesity and Metabolism, Volume 28, Issue 7, Page 5926-5938, July 2026.ABSTRACT Aims Elevated fasting glucagon is linked to hyperglycemia, but postprandial glucagon effects are less understood. Recent evidence suggests metabolic benefits of rising glucagon after oral glucose intake, potentially impacting brain‐mediated whole‐body metabolism.

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingAnalyzing hyperspectral images (HSIs) using supervised classification is challenging, primarily because of the higher spectral dimensions and the presence of rich and complex spatial information. This article proposes a strategy for pixel vector ordering

Nanophotonics, Volume 15, Issue 12, 25 June 2026.A hybrid metasurface composed of Ge dielectric pillars and a VO₂ grating is proposed, which enables functional switching between symmetric and asymmetric polarization conversion in transmission. By continuously tuning the conductivity of VO2, the structure achieves multiple dynamic controls of asymmetric transmission, circular dichroism, and ...
