Soccer heading does most damage to brain area critical for cognition, brain imaging study finds
A brain imaging technique developed by Columbia researchers has identified areas in the brain's cerebral cortex—just behind the forehead—that are most damaged by the repetitive impacts from heading a soccer ball. Their study also found that the damage leads to cognitive deficits seen in soccer players who head the ball frequently.

Cognition releases SWE-1.5, a new coding model in Windsurf, saying it partnered with Cerebras to serve SWE-1.5 at speeds up to 13x faster than Claude Sonnet 4.5 (Cognition)

Cognition | Introducing SWE-1.5: Our Fast Agent Model
Today we’re releasing SWE-1.5, the latest in our family of models optimized for software engineering. It is a frontier-size model with hundreds of billions of parameters that achieves near-SOTA coding performance. It also sets a new standard for speed: we partnered with Cerebras to serve it at up to 950 tok/s – 6x faster than Haiku 4.5 and 13x faster than Sonnet 4.5. SWE-1.5 is now available in Windsurf!

I can foresee website hosting plans being split into "browser only" (requiring proof-of-work/proof-of-cognition cookies) and "open" (to bots, including archives and search engine indexers).
The AI scrapers (and, to some extent, many more unauthorised pen-testers) have made dynamic websites far more expensive to run over the last year or two.

Epistemological Fault Lines Between Human and Artificial Intelligence
Large language models (LLMs) are widely described as artificial intelligence, yet their epistemic profile diverges sharply from human cognition. Here we show that the apparent alignment between human and machine outputs conceals a deeper structural mismatch in how judgments are produced. Tracing the historical shift from symbolic AI and information filtering systems to large-scale generative transformers, we argue that LLMs are not epistemic agents but stochastic pattern-completion systems, for…

There’s other reasons as well, but at its core it doesn’t even _try_ to model intelligence or cognition

Natural brain opioids help us 'see the bigger picture' after rewards
Feeling good doesn't just lift our mood—it also helps us stay flexible and resilient. A new study by an international team of neuroscientists shows that natural brain opioids released after rewards play a key role in broadening attention, offering fresh insights into stress, cognition, and well-being.

Structured Cognition for Behavioral Intelligence in Large Language Model Agents: Preliminary Study
Large language models have advanced natural language understanding and generation, yet their use as autonomous agents raises architectural challenges for multi-step tasks. Existing frameworks often intertwine inference, memory, and control in a single prompt, which can reduce coherence and predictability. The Structured Cognitive Loop (SCL) is introduced as an alternative architecture that separates these functions. In SCL, the language model is dedicated to inference, memory is maintained exte…

Spin quantum computing, spin quantum cognition
Over two decades ago, Bruce Kane proposed that spin-half phosphorus nuclei embedded in a spin-zero silicon substrate could serve as a viable platform for spin-based quantum computing. These nuclear spins exhibit remarkably long coherence times, making them ideal candidates for qubits. Despite this advantage, practical realisation of spin quantum computing remains a challenge. More recently, physicist Matthew Fisher proposed a hypothesis linking nuclear spin dynamics, specifically those of phosp…

Brain health could be improved with high-fat, low-carb diet, study finds
There may be a way to protect brain energy to preserve cognition—and the secret could lie on your plate. Think fish and seafood, meat, non-starchy vegetables, berries, nuts, seeds, eggs and even high-fat dairy products.
