Asymmetric reduction of internal alkenes catalyzed by nickel carbene and Heck coupling reactions

Researchers develop a nickel carbene catalyzed asymmetric reduction of internal alkenes, achieving highly regioselective and enantioselective functionalization of inner alkenes. The method uses sterically hindered and tunably flexible NHC ligands, suppressing side reactions and achieving precise stereocontrol.

Tropical mountain forests: Canopy and understory show sharply different biodiversity patterns across elevation

Researchers found that tree-layer α-diversity peaks at mid-elevation zones, while understory α-diversity shows a bimodal trend with two diversity peaks at 400-600m and 1000-1200m. Community composition differs among low-, mid- and high-elevation zones, driven by species turnover across elevational zones.

The framing of nature changes how kids respond to environmental education

A randomized trial in 21 Japanese elementary schools found that students respond more strongly to environmental education when nature is framed around its human benefits rather than its intrinsic value. This approach increased students' short-term interest in the environment. In contrast, students who received an ecocentric framing sho...
