This theory suggests that reality is not fully fixed in advance but becomes progressively defined through observation and interaction with gravitational potentials: Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
* The author proposes that dark matter and dark energy are not physical substances, but rather effective phenomena arising from quantum corrections to gravity.
* Using the Wigner–Moyal equation, the study suggests that higher-order quantum terms act as additional forces depending on the observer's resolution of phase space.
* The research interprets "dark matter" as these quantum-corrected forces appearing in high-curvature environments like galaxies.
* The model accounts for "dark energy" by suggesting that reduced gravitational potential at cosmic distances causes a transition toward classical dynamics, mimicking accelerated expansion.
* This framework aims to explain relativistic effects and galactic rotation curves without invoking new particles or mathematical singularities.

This editorial discusses how genomic studies are being used to understand the origins of language in humans. Researchers are attempting to pinpoint the earliest divergence in modern human populations, specifically between the Khoisan people of southern Africa and the rest, to establish a lower bound for when linguistic capacity developed – at least 135,000 years ago. The article highlights the difficulty in reconstructing very old languages, pointing out that many early languages are "known unknowables," lost to time. It acknowledges the distinction between linguistic capacity and fully formed language, suggesting the former may have predated the latter.
Researchers have identified a neural network associated with adaptive mentalization – the ability to adjust how we infer others’ intentions and beliefs based on their behavior. Using computational modeling and fMRI, they found activity and connectivity within brain regions (including the temporoparietal junction) tracked participants’ ability to update beliefs about opponents' strategic sophistication in a game setting. This neural signature could potentially be used to assess mentalization capabilities in both healthy individuals and those with brain disorders.
An introduction to semantic model-driven AI, exploring how SHACL (Shape Constraint Language) can improve the reliability of LLM responses by providing structure and constraints to data.
Quantum Darwinism: Zurek argue that certain quantum states ("pointer states") are better at creating multiple, identical copies of themselves in the environment through entanglement. This "survival of the fittest" information is what we perceive as classical reality. The environment essentially "selects" these states, leading to a shared, objective reality.
A physicist explores the simulation hypothesis – the idea that our reality could be a computer simulation – and its implications, drawing on philosophy, technology, and scientific observations.
This article explores the Boltzmann brain hypothesis, the time-asymmetry of memory, and the second law of thermodynamics, formalizing their relationships within a time-symmetric, time-translation invariant Markov process framework. It disentangles these concepts to avoid circular reasoning and offers a novel formal approach to their investigation.
An exploration of SHACL 1.2 UI and its potential for creating forms and views, drawing parallels to the earlier XForms technology. The article discusses the benefits of declarative UI generation, dynamic properties, and security features.
The article explores SHACL 1.2 UI as a powerful, declarative approach to building forms and views for RDF data, drawing parallels to the earlier (and ultimately unsuccessful) XForms standard. The author argues that SHACL 1.2 UI offers benefits like consistent data presentation, automated form generation, dynamic property computation, and enhanced security, potentially revolutionizing how we interact with data on the web. While current tooling is limited, existing DASH-compatible tools can be adapted, and the author envisions a future where data itself dictates its presentation, reducing the need for costly and inconsistent manual form creation.

A new paper by SFI Professor David Wolpert introduces a mathematically precise framework for the simulation hypothesis, challenging several long-standing claims and opening up new questions about simulated universes.
An exploration of the role of an ontologist, covering skills, tasks, differences from taxonomists, training resources, and the future of the field.
