The website "WTF Happened In 1971?" presents a collection of graphs depicting various socio-economic indicators in the United States, primarily spanning from the post-World War II era to the present day. The overarching implication of the website is that a significant inflection point occurred around 1971, after which several key metrics seemingly diverged from their previously established trends. This divergence often manifests as a decoupling between productivity and compensation, a stagnation or decline in real wages, and a dramatic increase in metrics related to cost of living, such as housing prices and healthcare expenses.
The website does not explicitly propose a singular causative theory for this shift. Instead, it presents a compelling visual argument for the existence of a turning point in American economic history, inviting viewers to draw their own conclusions. The graphs showcase a variety of indicators, including, but not limited to:
Productivity and real hourly wages: These graphs illustrate a strong correlation between productivity and wages prior to 1971, with both rising in tandem. Post-1971, however, productivity continues to climb while real wages stagnate, creating a widening gap. This suggests that the benefits of increased productivity were no longer being equitably distributed to workers.
Housing prices and housing affordability: The website depicts a sharp escalation in housing costs relative to income after 1971. This is visualized through metrics like the house price-to-income ratio and the number of years of median income required to purchase a median-priced house. This indicates a growing difficulty for the average American to afford housing.
Healthcare costs: Similar to housing, the cost of healthcare exhibits a dramatic increase after 1971, becoming a progressively larger burden on household budgets.
Debt levels (both household and national): The website presents graphs showcasing a substantial rise in debt levels, particularly after 1971. This includes metrics like household debt as a percentage of disposable income and the national debt as a percentage of GDP, suggesting a growing reliance on borrowing to maintain living standards.
College costs and college tuition as a percentage of median income: The cost of higher education undergoes a significant increase post-1971, making college less accessible for many.
Income inequality: The website visually represents the growing disparity in income distribution, with the share of wealth held by the top 1% increasing significantly after 1971, further exacerbating the economic challenges faced by the majority of the population.
In essence, "WTF Happened In 1971?" visually argues that a fundamental change occurred in the American economy around that year, marked by decoupling of productivity and wages, exploding costs of essential goods and services like housing and healthcare, and a widening gap between the wealthy and the rest of the population. The website refrains from explicitly attributing this shift to any specific cause, leaving the interpretation and analysis to the observer.
This groundbreaking study, titled "Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep," elucidates the intricate interplay between the neurotransmitter norepinephrine, the rhythmic fluctuations of blood vessels known as vasomotion, and the brain's waste clearance system, the glymphatic system, during sleep. The research meticulously investigates the mechanisms by which sleep facilitates the removal of metabolic byproducts from the brain, a critical process for maintaining neurological health. Employing advanced two-photon imaging in live mice, the researchers directly visualized and quantified cerebrospinal fluid (CSF) flow within the glymphatic system under varying conditions. Their findings reveal a strong correlation between norepinephrine levels and the efficacy of glymphatic clearance. Specifically, they observed that during sleep, when norepinephrine levels are naturally reduced, slow vasomotion is amplified. This slow, rhythmic dilation and constriction of blood vessels, particularly in the arterioles, appears to act as a pumping mechanism, optimizing the influx of CSF into the brain parenchyma and thereby enhancing the clearance of waste products, including potentially neurotoxic proteins like amyloid-β. Conversely, during wakefulness, characterized by elevated norepinephrine levels, slow vasomotion is suppressed, resulting in diminished glymphatic flow and consequently reduced waste clearance. Furthermore, the researchers elegantly demonstrated the causal link between norepinephrine and glymphatic function through pharmacological manipulations. By artificially increasing norepinephrine levels during sleep, they successfully inhibited slow vasomotion and impaired glymphatic clearance. Conversely, by blocking the actions of norepinephrine, they were able to augment slow vasomotion and enhance glymphatic flow even during wakeful states. These findings underscore the critical role of norepinephrine in regulating glymphatic clearance and provide compelling evidence for the importance of sleep in maintaining brain health by facilitating the efficient removal of metabolic waste products. The study sheds new light on the complex physiological processes underlying sleep and its restorative functions, suggesting potential therapeutic avenues for neurological disorders associated with impaired glymphatic clearance, such as Alzheimer's disease. This detailed understanding of the norepinephrine-vasomotion-glymphatic axis may pave the way for novel interventions aimed at bolstering the brain's natural waste removal system and mitigating the accumulation of harmful substances.
The Hacker News post titled "Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep," linking to a Cell journal article, has generated several comments discussing the research and its implications.

However, they also cautioned about the potential downsides of relying heavily on third-party code, specifically the risks associated with unknown vulnerabilities or breaking changes in dependencies.
A few commenters delved into technical aspects. One user discussed the nature of transitive dependencies, where a single direct dependency can pull in many others, leading to a large overall count. They also pointed out that some Rust crates are quite small and focused, potentially inflating the dependency count compared to languages with larger, more monolithic standard libraries.
Another technical point raised was the difference between a direct dependency and a transitive dependency, highlighting how build tools like Cargo handle this distinction. This led to a brief comparison with other languages' package management systems.
The implications of dependency management in different programming language ecosystems was another recurrent theme. Some commenters with experience in Go and Java chimed in, offering comparisons of typical dependency counts in those languages for similar projects.
Finally, a few users questioned the overall design and architecture choices made in the project, speculating whether the reliance on so many crates was genuinely necessary or if a simpler approach was possible. This discussion hinted at the broader question of balancing code reuse with self-sufficiency in software projects. However, this remained more speculative as the commenters did not have full access to the project's codebase beyond what was described in the article.
In a momentous decision with significant implications for the comestible landscape of the United States, the Food and Drug Administration (FDA) is poised to institute a prohibition on the utilization of Red Dye No. 3, a synthetic color additive commonly employed in a plethora of processed food products. This regulatory action, anticipated to ripple through the food industry, stems from long-standing concerns regarding the potential carcinogenic properties of the aforementioned dye, specifically its purported link to thyroid tumors in animal studies. This move represents a culmination of decades of scrutiny and advocacy surrounding the safety of Red Dye No. 3, with previous attempts to restrict its use facing resistance from industry stakeholders.
The impending ban, which will affect a wide array of consumer goods, including but not limited to breakfast cereals, candies, baked goods, and beverages, represents a substantial victory for consumer safety advocates who have long championed stricter regulations on food additives. While manufacturers have historically defended the use of Red Dye No. 3, citing its efficacy in enhancing the visual appeal of their products and its compliance with existing regulatory thresholds, the FDA’s decision underscores a shift towards prioritizing public health concerns over aesthetic considerations.
The agency’s determination to ban Red Dye No. 3 arises from a renewed evaluation of scientific evidence, which, according to the FDA, indicates a demonstrable link between the consumption of the dye and the development of thyroid cancer in laboratory animals. Although the precise mechanisms by which the dye induces carcinogenesis remain under investigation, the FDA has determined that the existing data warrant precautionary measures to mitigate potential risks to human health. This decision signifies a more proactive approach to food safety regulation, reflecting a growing awareness of the potential long-term health consequences of exposure to even seemingly innocuous food additives.
The forthcoming ban on Red Dye No. 3 will necessitate reformulations across a broad spectrum of food products, requiring manufacturers to identify and implement alternative coloring agents that meet both regulatory standards and consumer expectations. This transition period may present challenges for the food industry, but ultimately aims to foster a safer and more transparent food supply for the American public. The FDA's decision marks a significant milestone in the ongoing dialogue surrounding food safety and underscores the importance of rigorous scientific evaluation in safeguarding public health.
