The 'Second Shift' Is Not Why Women Avoid News
Women are more likely than men to avoid political and economic news, but the reasons for this behaviour are linked less to structural inequality or family-related stress than to personal attitudes and the emotional perception of news content. This conclusion was reached by HSE researchers after analysing data from a large-scale survey of more than 10,000 residents across 61 regions of Russia. The study findings have been published in Woman in Russian Society.

Heterocycle-fused cyclopentadienyl metal complexes: Heterocene synthesis, structure and catalytic applications

Coordination Chemistry Reviews. 2021. Vol. 426. P. 213515.
Nifant'ev E., Ivchenko P., Vinogradov A.

Metallocenes of the group 4 metals have attracted great attention as precursors of single-site catalysts forthe production of advanced polyolefins. The annelation of a cyclopentadienyl ring with a heterocyclicfragment fundamentally changes the electronic and structural characteristics ofg5-coordinated ligandsand provides new dimensions for the design of novel and effective catalysts. Heterocycle-fused half-sandwich and sandwich metal complexes, called heterocenes, have been extensively studied since theearly 2000s. This review describes the different synthetic strategies employed in the preparation ofheterocycle-fusedg1-g5andg5-g5ansa-ligand precursors, and further, discusses the synthesis, molec-ular structure, and catalytic applications of heterocenes.

Cu(I) acetylide clusters decorated with pyridylphosphine ligands: structural diversity, cuprophilic interactions and phosphorescence properties
Baranov A., Bagryanskaya I., Novikov A. et al., Inorganic Chemistry Communications 2026 Vol. 189 Article 116670
The reaction of copper(I) phenylacetylide [PhC ≡ CCu]n with the 2-pyridylphosphines (tBu2PyP and Ph2PyP) offers a straightforward route to structurally diverse clusters. With tBu2PyP, a trinuclear cluster [Cu3(C ≡ CPh)3(tBu2PyP)3] featuring a Cu3 triangular was isolated. Surprisingly, the reaction of [PhC ≡ CCu]n with Ph2PyP yields two isomeric clusters [Cu4(C ≡ CPh)4(Ph2PyP)4] with tetrahedral or zigzag-arranged Cu4 cores. Upon prolonged storage in acetonitrile, the tetrahedral Cu4 cluster converts to ...

Dipolar [3+2] Cycloaddition of Nitrones to 3-Aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones
Khramtsova E. E., A. S. Novikov, Dmitriev M. V., Russian Journal of Organic Chemistry 2026 Vol. 62 Article 12
The dipolar [3+2]-cycloaddition reactions of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones with diarylnitrones lead to the formation of benzo[b]isoxazolo[5',4':2,3]pyrrolo[1,2-d][1,4]thiazines. The reac- tion proceeds stereoselectively to form exclusively the (2aS*,3R*,5aS*) diastereomers. Density functional theory computations for the model reaction showed that the (2aS*,3R*,5aS*) diastereomers are both kinetically and thermodynamically preferred over the alternative (2aS*,3S*,5aS*) diastereomers. At room temperature in solution, the ...

Theory of capillary-induced self-coacervation in zwitterionic polymer solutions
Nikolai N. Kalikin, Petr E. Brandyshev, Yury A. Budkov, Journal of Chemical Physics 2026 Vol. 164 No. 15 Article 154904
This study presents a mean-field theory for zwitterionic polymer solutions confined within attractive slit-like nanopores. Building upon our prior model for self-coacervation [Budkov et al., Soft Matter 19, 3281–3289 (2023)], we demonstrate that strong electrostatic dipole–dipole correlations between monomeric units, coupled with attraction to pore walls, can induce capillary-driven liquid–liquid phase separation inside the pore—a ...
