Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

open access: yesAndrology, Volume 14, Issue 2, Page 496-515, February 2026.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

Narrative Self‐Transcendence: Decreased Regret and Increased Acceptance Over Late Midlife

open access: yesJournal of Personality, Volume 94, Issue 1, Page 137-150, February 2026.
ABSTRACT Introduction Self‐transcendence—connectedness within and beyond the self—is a complex phenomenon theorized to increase with age, but evidence is mixed. This longitudinal study is the first to investigate changes in self‐transcendence across late midlife using life story narratives.

The CNGS neutrino beam

open access: yesNuclear Physics B - Proceedings Supplements, 2007
The CNGS (CERN Neutrinos to Gran Sasso) project aims to produce a muon neutrino beam for the investigation of the oscillations of neutrinos. The beam is directed from CERN SPS accelerator to the Gran Sasso National Laboratory (LNGS) of the INFN in Italy, 730 km from CERN, where the OPERA experiment is designed to search for the appearance of tau ...
