The VC Bubble Bursts: A Looming Winter?

2025-08-28

An analysis based on SEC Form D filings reveals an impending VC bubble burst. By tracking the number of Form Ds containing phrases like "Fund I", "Fund II", etc., the author shows that VC fund raising peaked in Q3 2022 before sharply declining. This is linked to the surge in VC funds during low-interest rate periods and the rise of "SPV-as-a-service" companies. The author predicts a significant decrease in available VC funding, driven by the typical 10-year lifespan of funds and a 2-4 year deployment period, now passing its peak. This coincides with the AI investment boom, leading to inflated valuations. The author concludes that future funding will drastically decrease, valuations will fall, many companies will struggle, and the AI hype cycle will cool.

Lithium Deficiency Could Be a Key Driver of Alzheimer's, Study Suggests

Lithium Deficiency Could Be a Key Driver of Alzheimer's, Study Suggests

A new study reveals that individuals with Alzheimer's disease exhibit lower brain lithium levels. Experiments with mice showed that supplementing lithium reversed cognitive decline in animals with Alzheimer's-like symptoms. Analysis of brain tissue from 285 deceased individuals revealed a 36% lower lithium concentration in the prefrontal cortex of Alzheimer's patients compared to those without cognitive impairment. Interestingly, amyloid plaques in Alzheimer's brains contained significantly higher lithium levels than plaque-free regions. Further research using lithium-deficient mice demonstrated impaired memory, increased brain inflammation, and reduced amyloid plaque clearance. However, treatment with low-dose lithium, particularly lithium orotate, improved memory and reduced plaque buildup in these mice. While promising, clinical trials are necessary to validate the safety and efficacy of low-dose lithium orotate as a potential Alzheimer's treatment.

Microplastics Found in Human Brains: A Spoonful of Worry

A groundbreaking study published in Nature Medicine reveals alarming levels of microplastics and nanoplastics in human brains—up to seven grams, roughly the weight of a teaspoon. The concentration increased by about 50% between 2016 and 2024, with higher levels found in individuals with dementia. While a causal link to dementia isn't established, the sheer presence of these particles deep within the brain is concerning. Researchers hypothesize that microplastics may travel to the brain via the bloodstream, binding to fats. This discovery underscores the urgent need for reducing microplastic exposure and further research into the long-term health impacts.

Refuting Fukuyama: Life Extension Isn't the Apocalypse

This article refutes Francis Fukuyama's arguments against life extension. Fukuyama claims it's physiologically impossible and would lead to societal sclerosis. The author counters that we're already extending healthspans through interventions like statins and GLP-1s. Furthermore, brain plasticity allows for cognitive function well into old age. The author argues that the benefits of longer lifespans—increased innovation and lower healthcare costs—far outweigh the potential risks. Life extension is a design problem, not a philosophical roadblock.

Kiwi's Giant Egg: A Mystery Solved?

The flightless kiwi bird lays an egg that can weigh up to a quarter of its body mass, a phenomenon long attributed to a legacy from larger ancestors. However, new DNA analysis challenges this theory, suggesting the kiwi's giant egg is an adaptation developed as it evolved from a smaller flying bird. The oversized egg allows kiwi chicks to be more precocial, increasing their survival rate in an environment with few ground predators but numerous aerial ones. This research reshapes our understanding of kiwi evolution and avian evolutionary processes.

US Trade Deficit: A Tale of Saving and Investment

US Trade Deficit: A Tale of Saving and Investment

The persistent US trade deficit isn't simply due to insufficient exports; it's fundamentally linked to a macroeconomic imbalance. The article uses national accounting to demonstrate the equivalence between the trade deficit and the gap between domestic saving and investment spending. Analyzing household, business, and government savings, it shows how their interplay affects the overall saving rate. The author argues that while trade policies like free trade agreements or industrial policy can influence trade composition, they won't solve the deficit unless they also address the saving-investment gap. Closing this gap, however, presents a significant challenge.

Samuel Pepys' Diary: A Timeless Bestseller

2025-06-11

Samuel Pepys' diary was first published in June 1825 and became an instant success. Newspapers featured reviews quoting memorable passages, such as his descriptions of the Great Fire of London, his new wig, and his first cup of tea. Subsequent editions followed, and by the end of the 19th century, it was celebrated as a classic of British history and literature. Today, Pepys is a star of museum exhibits and historical novels, and excerpts from his diary are used to introduce students to the Restoration period and even to history itself; six-year-olds in England, following the National Curriculum, can recount how Pepys buried his expensive cheese to save it from the fire.

US Anti-Piracy Symposium Pushes for Site Blocking

2025-01-29

A recent USPTO anti-piracy symposium highlighted the need for site blocking in the US. Experts discussed the evolution of piracy into a sophisticated, multi-level industry offering "piracy as a service." The brazen behavior of some pirates, openly advertising and even trademarking their services, further emphasizes the urgency. While site blocking is effective in over 50 countries, the US lags behind, partly due to the 2012 SOPA failure. The symposium advocated for a dynamic US site-blocking system, learning from international examples to avoid overblocking and swiftly target new pirate domains.

Don't Argue with Toddlers (or Their Adult Equivalents)

This article argues that many apparent arguments are not genuine exchanges of ideas, but rather displays of power, attention-seeking behaviors, or playful sparring. True arguments aim for insight and a conclusion. The author suggests that a willingness to change one's own mind is crucial; if you're not changing your perspective, you're likely not engaging in a real argument. Instead of trying to win, focus on asking open-ended questions like, "What information might change your mind?" The piece concludes that deeply held beliefs tied to identity are often resistant to change through argument.

Mathematical Modeling Reveals Just How Bad the Dreidel Game Is

Last year, the author used the PRISM probabilistic modeling language to model the traditional holiday game Dreidel, proving its lack of fun. This year, he refined the model to simulate the entire game until its conclusion. The new model corrects the previous flaw of only simulating the elimination of the first player and improves the calculation logic for betting and player elimination. Through model simulation, the author found that, on average, a four-player game takes 760 spins to end, and the longest can even exceed 6 hours. This fully proves that the Dreidel game is long, tedious, and frustrating.
