Researchers have developed a novel mathematical model that treats biological tissue as a fluid composed of elongated, aligned particles to explain how surrounding cellular forces influence the speed and shape of wound closure. The model demonstrates that the structural orientation of cells around a wound actively dictates healing dynamics.

Physicist Proposes Dark Matter Is Made of Black Holes That Survived Dead Universes

Dark matter could be made of "relic" black holes that survived the collapse of previous universes, a new model proposes.

Well that takes a load of my mind - I'm glad we got to the bottom of this!

Researchers @ University of Pennsylvania have confirmed that gravity's strength weakens with distance almost exactly as predicted by the equations developed by Newton and later incorporated into Einstein's theory of general relativity. https://phys.org/news/2026-04-gravity-newton-einstein-cosmic-scales.html #Gravity #Newton #Einstein #GeneralRelativity #TheoreticalPhysics #Physics #Astrophysics #Universe #Galaxies #UniversityofPennsylvania

"The Blob" is a pioneering experimental setup in which a perfect, stationary ball of turbulence is generated at the center of a water tank by firing synchronized water jets. This configuration isolates the chaotic swirling of fluids from boundary interactions, allowing scientists to study turbulence in its purest, undisturbed form.

New preprint submitted to Classical and Quantum Gravity:

GR is time-symmetric. That symmetry is the root of singularities, information loss, and the arrow of time.

We propose the opposite: irreversibility is fundamental.

Main result: gravitational collapse halts before any trapped surface forms. C_max < 1. No quantum gravity needed.

Entropic I‑Field Theory: Fundamental Irreversibility and the Resolution of Singularities, Information Loss, and the Arrow of Time

General relativity is time-symmetric. This symmetry is the root of its three deepest puzzles: singularities, information loss, and the arrow of time. All existing approaches treat irreversibility as emergent — a statistical mirage atop a reversible microreality. We propose the opposite.   Irreversibility is fundamental. It is encoded in a classical scalar field $I$ — the I-field — that couples universally to gravity and matter. Its dynamics are governed by an Euler-Lagrange-Rayleigh action, where a dissipation term $\gamma u^\mu \nabla_\mu I$ breaks time-reversal symmetry at the level of the field equation. The modified Einstein equations introduce a dimensionless stabilization index $\eta$ that quantifies I-field backreaction.  The consequences are direct:  -   Gravitational collapse halts at a finite critical density $\rho_c$, before a trapped surface can form. The maximal compactness satisfies $\mathcal{C}_{\max} < 1$.  -   No event horizon ever appears — information remains causally accessible throughout the evolution.  -   The arrow of time emerges from the field dynamics, not from boundary conditions or statistical postulates.  Three foundational problems are thus resolved within a single classical framework, from first principles, without invoking quantum gravity.

Thermodynamic Topology of 4D Charged AdS Black Holes with $F^{αβ}F^{γλ}R_{αγβλ}$ Coupling

We investigate the thermodynamic phase transitions of a four-dimensional charged anti-de Sitter black hole endowed with a non-minimal coupling of the form $F^{αβ}F^{γλ}R_{αγβλ}$. Using perturbative methods, we derive a consistent black hole solution and analyze its thermodynamics through both conventional equilibrium techniques and a topological defect classification approach. The system displays van der Waals-like critical behavior, with a swallow-tail structure in the free energy and distinct phase branches. The topological analysis independently confirms the existence of critical points and classifies the system within the universal topological scheme for black hole thermodynamics.
