Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest
Global Change Biology Communications, Volume 1, Issue 3, September 2026.Using a 20‐year eddy covariance record from a temperate deciduous forest, we show that net carbon uptake declined over two decades. Both the trend and interannual variability in net carbon exchange were respiration driven, with warming winters and increasing late‐summer diffuse light driving the trend in respiration.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Noûs, Volume 60, Issue 3, Page 511-535, September 2026.Abstract The present paper presents a new (formal) theory of presence according to which, roughly, to be present at a place is to have a delegate located at that place. One crucial feature of the theory is that something can be present at a place without thereby being located there.

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.Wet transfer of an atomically flat azo‐functionalized 2D covalent organic framework film onto monolayer MoS2 enables clean van der Waals heterostructure devices with reversible photoswitching and multilevel nonvolatile memory. ABSTRACT Two‐dimensional π‐conjugated covalent organic frameworks (2D π‐COFs) combine in‐plane π‐delocalization with periodic ...

Renaissance Studies, Volume 40, Issue 4, Page 635-689, September 2026.Abstract Pedro de Ayala served as a diplomat for King Ferdinand II of Aragon and Queen Isabella I of Castile at the courts of Henry VII, King of England, and James IV, King of Scots. In July 1498, he wrote a letter, partly in cipher, to report to his king and queen on such matters as Spain's interests in international diplomacy; the characters and ...

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement
Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract This study demonstrates the high‐resolution profiling of cloud microphysics in a laboratory chamber using Time‐Correlated Single Photon Counting (TCSPC) LiDAR. We present a novel retrieval method to derive vertical extinction (σ) $(\sigma )$ profiles, constrained by in situ measurements, to diagnose responses to dry‐air entrainment.
