We just preprinted a huge meta-meta-analysis examining the effects of exercise on cognition, memory, and executive function
In short
- 2239 effect sizes
- extreme between-study heterogeneity
- extensive publication bias
- some subgroup/exercise-specific effects

Erasing the history of the insurrection is not going to end well. You can't have a country that allows elected leaders to cover up crimes in the open without consequences. That's a broken country. People have to face ramifications for trying to coup or it's not a real country. This will happen again

![3 Project Iceberg: Sandbox for the Human-AI Workforce
Project Iceberg simulates the emerging human-AI workforce. It models how 151 million American
workers and emerging AI capabilities interact, allowing states to explore policy scenarios and
assess potential workforce exposure patterns before committing billions to infrastructure and
training programs. Built on MIT’s Large Population Models [10] and powered by Oak Ridge
National Laboratory’s Frontier supercomputer [13], Iceberg turns trillions of workforce data
points into scenario-planning capability.
Iceberg represents both sides of the emerging labor market: what human workers currently
do, and what AI systems are becoming capable of doing. By mapping these onto a shared skill
taxonomy, it simulates how work evolves under different assumptions about policy intervention,
adoption behavior, and technology readiness. The process unfolds in three steps (Fig 2):
Step 1 - Human Workforce Mapping: We construct a digital representation of the
workforce: 151 million workers across 923 occupations in 3,000 counties, covering more than
32,000 distinct skills [20, 36]. Each worker is modeled as an agent with attributes such as skills,
tasks, and location. This enables analysis of reskilling potential and occupational similarity,
which is essential for designing pathways when skills and tasks shift.
Step 2 – AI Workforce Mapping: We catalog over 13,000 AI tools - including copilots
and workflow automation systems - using the same skill taxonomy. This allows direct comparison
between human and AI capabilities. The alignment reveals where AI augments human work
(e.g. automating hospital paperwork so nurses can spend more time with patients) and where it
transforms tasks entirely (e.g. accelerating code generation requires engineers to shift towards
oversight, testing, and integration skills).
Step 3 - Human–AI Simulation: We combine these two populations in](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:7syfakzcriq44mwbdbc7jwvn/bafkreiehm4kwsdeeassiwwx2irb76eorxatra4z5sgt4ip23rdsugmpuya@jpeg)

Thankfully, she and many other women testified against him and something was finally done. This is her take on his case:
