Children &Society, EarlyView.ABSTRACT This article interrogates the politics of othering embedded in the taken‐for‐granted association of childhood, play, joy, and happiness. It explores how these notions are historically inscribed as forms of otherness tied to the affective normativity of joy.

The Structure of Vertebrate Antigen Receptor Repertoires: An Evolutionary Perspective
Immunological Reviews, Volume 341, Issue 1, August 2026.ABSTRACT In vertebrate adaptive immune systems, somatically diversified antigen receptors assume a central role in self/nonself discrimination. Attesting to the presence of a unique but unknown selective environment at early stages of vertebrate evolution, this facility emerged twice, in the ancestors of jawless and jawed vertebrates.

Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen
Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes
Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Countdown: Timespaces of Deadlines and Displacement
Population, Space and Place, Volume 32, Issue 5, July 2026.ABSTRACT This article examines how politically structured deadlines and their accompanying countdowns generate dynamics of displacement by shaping anticipations of violence and prompting accelerated migration. Drawing on ethnographic research on Burundi's 2015 third‐term crisis and The Gambia's 2017 electoral impasse, we show how constitutional ...

La «crise» sans fin de la modernité: naissance et avatars d’un thème chez Reinhart Koselleck
Revista de Historiografía, 2020 La question de la «crise» a occupé Reinhart Koselleck sa vie durant. A partir de sa thèse de doctorat, Kritik und Krise (1954), elle a très tôt déterminé sa perception du monde moderne – des guerres civiles confessionnelles du XVIe siècle jusqu’au long ...

Methanol Metabolism in the Cytochrome and Menaquinone‐Containing Acetogen Moorella thermoacetica
Environmental Microbiology, Volume 28, Issue 7, July 2026.The thermophilic acetogenic bacterium Moorella thermoacetica is a promising platform organism to convert C1 compounds to valuable products. Gaseous C1 substrates are technically difficult to use for fermentation in an industrial scale, but methanol, which can be produced chemically from carbon dioxide, is a suitable alternative.

Tempo e crise na teoria da modernidade de Reinhart Koselleck
História da Historiografia, 2011 Este artigo explora dois aspectos constitutivos da “teoria da modernidade” proposta pelo historiador alemão Reinhart Koselleck. O primeiro corresponde à sua interpretação da emergência da noção de “tempo histórico”; e o segundo, a seu argumento acerca da

The Russian Review, Volume 85, Issue 3, Page 348-362, July 2026.Abstract This article brings together theories of history and filmic realism to analyze the representation of the provinces in Nataliia Meshchaninova’s The Hope Factory (Kombinat “Nadezhda,” 2014) and Andrei Zviagintsev’s Leviathan (Leviafan, 2014). It argues that these two films share a typically realist attitude of respect toward the profilmic in ...

Teoría y práctica conceptual: vida de los conceptos, vida de la lengua
Isegoría, 2007 En este artículo se analiza el planteamiento de Reinhart Koselleck en torno a la Begriffsgeschichte desde el punto de vista de la productividad de la historia, el tiempo y la productividad propia de la dialéctica de los conceptos.
