Hydrogravimetry Enables Quantification of Alpine Groundwater Dynamics

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Groundwater plays a critical role in the functioning of alpine hydrological systems, and its importance is expected to increase under climate change. However, quantification of groundwater processes in these systems remains highly uncertain. Terrestrial time‐lapse gravimetry (TLG) is a geophysical and geodetic technique whose measured variable

Mycoponics: Controlled Bioproduction Utilizing Biophysical, Solid‐State, Liquid Nutrient Delivery

Biotechnology Journal, Volume 21, Issue 2, February 2026.
Graphical Abstract and Lay Summary Mycoponic biotechnology, inspired by hydroponics—is enabled by antimicrobial ceramics as “substrate,” using a complete mycoponic media for continuous bioproduction of mycelial and mushroom products. Applications include food, mycoleather, and mycopharmaceuticals, representing 18% of the global market.

Loop Quantum Gravity Vacuum with Nondegenerate Geometry

Symmetry, Integrability and Geometry: Methods and Applications, 2012
In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry.

Sine-dilaton gravity vs double-scaled SYK: exploring one-loop quantum corrections

Journal of High Energy Physics
We provide non-trivial checks of the recently proposed duality between double-scaled SYK and a 2d dilaton gravity model with sine potential, studying the path integral at one-loop level.

Newtonian gravity in loop quantum gravity

, 2010
We apply a recent argument of Verlinde to loop quantum gravity, to conclude that Newton's law of gravity emerges in an appropriate limit and setting. This is possible because the relationship between area and entropy is realized in loop quantum gravity when boundaries are imposed on a quantum spacetime.

Traversable wormholes from Loop Quantum Gravity

Journal of Cosmology and Astroparticle Physics
Abstract This study introduces and investigates Lorentzian traversable wormhole solutions rooted in Loop Quantum Gravity (LQG). The static and spherically symmetric solutions to be examined stem from the energy density sourcing self-dual regular black holes discovered by L.

Quantum General Invariance and Loop Gravity

Foundations of Physics, 2001
A quantum physical projector is proposed for generally covariant theories which are derivable from a Lagrangian. The projector is the quantum analogue of the integral over the generators of finite one-parameter subgroups of the gauge symmetry transformations which are connected to the identity.

Massive particles tunneling from quantum Oppenheimer-Snyder black holes and black hole entropy

Physics Letters B
In this paper, we investigate the tunneling process of massive scalar particles from a quantum Oppenheimer-Snyder black hole using the tunneling approach proposed by Parikh and Wilczek.
