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.
A pair of landmark studies has identified the originators of the Indo-European family of languages in current-day Russia about 6,500 years ago, the Caucasus Lower Volga people.
>“We can see there was a small group of villages 5,700 to 5,300 years ago with just a couple thousand breeding individuals,” Reich said. “And then there was a demographic explosion, with these people going everywhere.”

The Langlands programme has inspired and befuddled mathematicians for more than 50 years. A major advance has now opened up new worlds for them to explore.
The article details the recent proof of the geometric Langlands conjecture, a significant advancement in mathematics that validates a decades-old program aiming for a "grand unified theory" of the field. Led by Dennis Gaitsgory and Sam Raskin, the proof—spanning five papers and nearly 1,000 pages—is expected to open new avenues of research and potentially bridge connections between mathematics and theoretical physics, particularly in understanding symmetries in quantum field theory. While not a complete solution to the broader Langlands program, it provides strong evidence for its underlying principles and offers new tools for tackling complex mathematical problems.
