Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Structure and Activity of Class II Lanthipeptides From a Thermophilic Bacterium

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Heterologous coexpression of the lanthipeptide synthetase TlaM from the thermophilic bacterium Thermoactinomyces sp. DSM 45891, with the precursor peptides TlaA1 and TlaA2 in Escherichia coli, resulted in the introduction of four thioether rings in both peptides.

Relational dynamics and Page-Wootters formalism in group field theory [PDF]

Quantum
Group field theory posits that spacetime is emergent and is hence defined without any background notion of space or time; dynamical questions are formulated in relational terms, in particular using (scalar) matter degrees of freedom as time.

Feasibility of upright carbon ion radiotherapy for prostate cancer: Dosimetric comparison between supine and upright postures

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Carbon ion radiotherapy (CIRT) in the upright posture is a treatment technique which delivers carbon ion beams from a fixed direction to patients who sit or stand on a rotating chair. Although various potential advantages of the upright positioning have been discussed, feasibility of upright CIRT for prostate cancer has not been ...

Decoherence of quantum superpositions in near-extremal Reissner-Nordström black holes with quantum gravity corrections

Journal of High Energy Physics
We study the quantum gravity corrected decoherence of quantum superpositions in the near-extremal Reissner-Nordström black holes. By employing the effective field theory approach, we model the black hole as a quantum system coupled to an external source ...

The Space of Connections as the Arena for (Quantum) Gravity

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We review some properties of the space of connections as the natural arena for canonical (quantum) gravity, and compare to the case of the superspace of 3-metrics.

Description of the rate‐limiting hydrogen tunneling mechanism for plant 9‐ and 13‐lipoxygenases

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Soybean lipoxygenase (GmLOX1), a plant 13‐LOX, has long been considered a model protein for non‐trivial, quantum hydrogen tunneling in enzyme catalysis. Hydrogen tunneling mechanisms have also been confirmed for LOXs across mammalian, fungal, and bacterial kingdoms.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Quantum-Wave Equation and Heisenberg Inequalities of Covariant Quantum Gravity

Entropy, 2017
Key aspects of the manifestly-covariant theory of quantum gravity (Cremaschini and Tessarotto 2015–2017) are investigated. These refer, first, to the establishment of the four-scalar, manifestly-covariant evolution quantum wave equation, denoted as ...
