Cytotoxic Dihydroagarofuran Sesquiterpenoids Isolated From the Roots of Tripterygium wilfordii
Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.Ten undescribed dihydro‐β‐agarofuran derivatives were isolated from the roots of Tripterygium wilfordii. Their structures, including absolute configurations were elucidated by NMR, CD exciton chirality, ECD calculation, and single‐crystal x‐ray diffraction.

Triterpenes with α‐Glucosidase Inhibitory Activity from Euphorbia antiquorum
Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.Four new euphane triterpenes (1–3 and 5), comprising three mutarotational pairs (1–3), were isolated from E. antiquorum and structurally characterized via HR‐ESIMS, NMR and ECD. Assays for α‐glucosidase inhibitory activity showed that compound 5 exhibited the highest activity (IC5₀ = 13.60 µM) and was identified as a mixed‐type inhibitor. ABSTRACT Four

Experimental aspects of the quantum tomography of tau lepton pairs at a Higgs factory collider
European Physical Journal C: Particles and FieldsQuantum tomography of tau lepton pairs produced at a Higgs factory collider will enable measurements of their spin correlations arising from quantum entanglement. Such measurements rely on the ability to measure the components of and correlations between

Polarization Measurement of Gamma-Ray Bursts with Fermi-GBM: The Case of GRB 180720B
The Astrophysical JournalTo achieve confident nonzero polarization measurements for gamma-ray bursts (GRBs) we need sensitive polarimeters and bright GRBs. Here we report on the polarimetric analysis of the bright GRB 180720B using the Fermi Gamma-ray Burst Monitor (GBM).
