Yes, we CAM! First evidence of CAM photosynthesis in a carnivorous plant

Plant Biology, Volume 28, Issue 1, Page 272-281, January 2026.
Evidence for weak, facultative CAM is reported for the first time in a carnivorous plant, i.e., in Mexican representatives of Pinguicula (Lentibulariaceae). Abstract Crassulacean acid metabolism (CAM) is a photosynthetic adaptation enabling higher CO2 concentration close to Rubisco and increased water use efficiency.

A radiative neutrino mass model with leptoquarks under non-holomorphic modular A 4 symmetry

Journal of High Energy Physics
We investigate a radiative seesaw model with two leptoquarks under non-holomorphic modular A 4 symmetry. The leptons and quarks belong to non-trivial representations of the modular A 4 and the structures of their mass matrices are restricted.

Continuous‐Wave (CW) Photo‐CIDNP NMR Spectroscopy: A Tutorial

Magnetic Resonance in Chemistry, Volume 63, Issue 12, Page 1020-1034, December 2025.
ABSTRACT Photo‐chemically induced dynamic nuclear polarisation (photo‐CIDNP) is a nuclear spin‐selective magnetic resonance phenomenon that has traditionally been used to mechanistically study chemical reactions involving the (transient) formation of radical molecular species, extract EPR observables of short‐lived radicals, probe biomolecular ...

Implementation and Evaluation of Emission‐Driven Land‐Atmosphere Coupled Simulation in E3SMv2.1

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract Emissions‐driven (prognostic CO2) simulations are essential for representing two‐way carbon‐climate feedback in Earth System Models. We present an emissions‐driven land–atmosphere coupled biogeochemistry (BGC) configuration (BGCLNDATM_progCO2) in version 2.1 of the Energy Exascale Earth System Model (E3SMv2.1).

Probing new physics with charge asymmetries in 2 same-sign leptons plus jets final states at the LHC

Journal of High Energy Physics
We study the impact of new physics models in the charge asymmetry defined for LHC final states consisting of two same-sign leptons (2SSl, with l = e, μ) plus jets (N jets ≥ 2), with a center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV, where the main SM ...

When and Where Do Waterbirds Need Water? A General Approach for Inferring Candidate Restoration Areas From Spatio‐Temporal Variation in Surface Water Availability

Diversity and Distributions, Volume 31, Issue 12, December 2025.
ABSTRACT Aim Globally, about 850 bird species depend on surface water habitats either year‐round or during migration. However, large‐scale analyses examining how different groups of waterbirds are associated with surface water across various regions and during different seasons are lacking.

Meson mixing bounds on Z ′ mass in the alignment limit: establishing the phenomenological viability of the 331 model

Journal of High Energy Physics
We perform a systematic study of flavor-changing neutral currents (FCNCs) in the 331 model with right-handed neutrinos (331RHNs), analyzing constraints on the Z ′ boson mass from K-, D-, B d -, and B s -meson oscillations.

Undecay

Journal of High Energy Physics
Unstable particles decay sooner or later, so they are not described by asymptotic one-particle states and they should not be included as independent states in unitarity relations such as the optical theorem.

Barr-Zee diagrams at a high-energy muon collider

Journal of High Energy Physics
The sensitivity of electron EDM experiments has been increasing at a rapid pace, and could yield indications of new physics in the coming decade. An intriguing possibility is that an EDM signal could be generated by new, electroweak-charged particles at ...

In search of an invisible Z′

Journal of High Energy Physics
We consider extending the Standard Model by an anomaly-free and possibly flavour non-universal U(1) X gauge symmetry, whose breaking gives a Z′ boson that does not affect electroweak precision observables at tree-level or via 1-loop renormalisation group
