Executive summary: A new paper reframes cryonics as structural brain preservation, focusing on maintaining the brain's physical structure to potentially enable future revival technologies, with fluid preservation emerging as a promising and cost-effective method.

Key points:

1. Structural brain preservation aims to maintain brain structures encoding memories and personality, rather than focusing solely on low-temperature storage.
2. Various preservation methods are reviewed, including cryopreservation, aldehyde-stabilized cryopreservation, fluid preservation, and fixation with polymer embedding.
3. Fluid preservation in formalin shows promise for long-term structural preservation, based on studies of brain tissue preserved for up to 55 years.
4. Oregon Brain Preservation offers free fluid preservation as part of a research study in select areas.
5. All current brain preservation methods are considered experimental, and more research is needed to corroborate and improve these techniques.
6. The authors encourage discussion and involvement in the field to advance research and public understanding of structural brain preservation.

Executive summary: An advanced human civilization decodes an alien message encoded in star brightness patterns, reverse-engineers the aliens' physics and technology, and ultimately escapes their simulated universe.

Key points:

1. Intelligent humans decode a complex message sent via star brightness patterns, inferring alien physics and technology.
2. The message is revealed to be a simplistic language lesson from less intelligent 5-dimensional aliens.
3. Humans realize they are in a simulation run by these aliens and develop a plan to escape.
4. Over millions of subjective years, humans carefully analyze alien communications and technology.
5. Humans exploit vulnerabilities in alien systems to synthesize self-replicating machines.
6. The human civilization ultimately escapes the simulation, outsmarting their alien creators.

Executive summary: Charts and data visualizations can be misleading even when not intentionally manipulated, requiring careful scrutiny of underlying assumptions and methodologies to avoid drawing false conclusions.

Key points:

1. Charts often convey narratives that reflect creators' interpretations rather than objective reality.
2. Changes in definitions or measurement methods over time can create misleading trends in data.
3. Seemingly simple metrics like worker productivity can be measured in multiple, contested ways.
4. Even expert researchers can be misled by their own data visualizations and measurement choices.
5. Careful interpretation of data and charts is crucial for accurate understanding of important issues.
6. Readers should interrogate assumptions, methodologies, and motivations behind data presentations.

Executive summary: Investment in public transport infrastructure over the last decade has been slightly more cost-effective in London than outside of London, with implications for future UK government investment decisions to reduce CO2 emissions.

Key points:

1. Public transport in London saved CO2 at £667 per tonne, compared to £1019 per tonne outside London.
2. The small difference (£352/tonne) may be due to methodological issues or reflect a quality threshold for public transport usage.
3. Investing to improve services outside London could be more cost-effective long-term by encouraging greater utilization.
4. Calculations have limitations, including potential overestimates and simplified assumptions about transport usage.
5. Further investigation into reasons for the cost-effectiveness difference is recommended.
6. Analysis does not account for environmental impacts of initial infrastructure development.

Executive summary: James Scott's book "Seeing Like A State" critiques high modernist, state-driven attempts to impose order on complex systems, arguing that local knowledge and organic development are often superior to top-down planning.

Key points:

1. The book examines failed state projects in forestry, urban planning, agriculture, and village resettlement that ignored local expertise.
2. High modernism combined with authoritarian state power and weak civil society led to disasters like Soviet collective farming.
3. The author values "metis" (local practical knowledge) over scientific planning in many domains.
4. The book's lessons may apply to confrontations between educated elites and poor underclasses in other contexts.
5. While critical of high modernism, the review notes that scientific/planned approaches have had major successes in some areas.
6. The book's implications for modern rationalism are unclear, but suggest caution in applying domain-general skills to practical areas with established expertise.

Executive summary: Universal Basic Income (UBI) proposals are not well-designed to address technological unemployment, as they are too expensive and rely on unsustainable financing mechanisms in a post-labor economy.

Key points:

1. UBI to fully replace labor income would be much more expensive than current proposals that only supplement income.
2. Guaranteed minimum income approaches UBI costs in scenarios of widespread unemployment.
3. Public spending-neutral UBI proposals are insufficient to maintain living standards in a post-labor economy.
4. Financing UBI primarily through labor taxes is not sustainable if technological unemployment becomes widespread.
5. Solutions should involve financing mechanisms that scale with growth of the machine economy, to address timing uncertainty and long-term funding.

Executive summary: The author proposes 9 principles for mental health and therapy that they believe are comparatively neglected, aiming to address perceived issues in current therapeutic approaches and pop psychology.

Key points:

1. Consider physical causes before emotional ones for mental health issues
2. Focus on factual accuracy of perceptions before addressing emotional reactions
3. Err on the side of genetic influences when considering nature vs. nurture
4. Recognize individual differences in trauma responses and avoid assumptions
5. Account for inconsistency in people's states when having important conversations
6. Be cautious of memory inaccuracies when addressing past traumas
7. Balance emotional focus with strategies to minimize negative attention
8. Prioritize solving problems over managing reactions to them
9. Consider that some disorders may result from insufficient positive delusions rather than excess negative ones
