The Egg Crisis: How Bird Flu and Political Decisions Are Affecting Your Breakfast

Eggs, once a reliable and affordable staple in American kitchens, have become a luxury item as bird flu ravages poultry farms across the nation. This crisis extends beyond just breakfast tables, affecting restaurants, supply chains, and even politics, with rising prices adding to consumer frustrations about inflation.

Original article



The Soaring Cost of Eggs

The price surge has been dramatic. In certain areas, like Wisconsin, a carton of pasture-raised eggs can cost up to $10. Perhaps most striking is the comparison to gasoline—typically the benchmark for consumer price complaints—with eggs now costing $1.74 more per dozen than a gallon of gas. This unprecedented reversal has left many Americans reexamining their grocery budgets and food choices.

The impact reaches far beyond home kitchens. Major restaurant chains including Denny's and Waffle House have been forced to revise their menus in response to egg shortages and price increases. Meanwhile, grocery stores have implemented purchase limits on egg cartons to prevent hoarding and ensure more equitable distribution among consumers.

Bird Flu: The Culprit Behind the Crisis

The primary driver of this egg shortage is highly pathogenic avian influenza (HPAI), which has necessitated the culling of egg-laying hens across the country. Farmers have had to destroy infected flocks to prevent further spread of the disease, significantly reducing the nation's egg production capacity.

Beyond the immediate economic impact, there's growing public health concern. Nearly half of Americans worry about the possibility of bird flu mutating to cause human outbreaks. This anxiety is well-founded, as zoonotic diseases (those that jump from animals to humans) have been responsible for several major pandemics throughout history.

Political Implications and Response

The egg crisis presents a significant challenge for the Trump administration, which has only been in office for six weeks. While the bird flu outbreak predates his presidency, the administration's response has come under scrutiny. According to reports, mass government layoffs included an unspecified number of professionals working on the bird flu response—personnel who officials are now scrambling to rehire.

These layoffs, reportedly overseen by Elon Musk as part of broader government cuts, have been criticized as displaying "bureaucratic incompetence." Only about one-third of Americans express satisfaction with President Trump's handling of prices, suggesting political vulnerability on economic issues.

Leadership Questions

Further complicating matters is the appointment of Kyle Diamantas, described as a 37-year-old Miami attorney and hunting companion of Donald Trump Jr., as the acting deputy commissioner for human foods at the Food and Drug Administration. In this role, Diamantas is responsible for overseeing safety for 80% of the nation's food supply, including managing threats like avian influenza.

Critics question whether his experience qualifies him to address complex food safety challenges, particularly during a crisis of this magnitude. His LinkedIn profile has been described as "a study in brevity," raising concerns about his relevant expertise.

The Broader Impact

The egg shortage illustrates how disruptions in one sector can ripple throughout society. Beyond breakfast, eggs are crucial ingredients in countless recipes, condiments, and processed foods. The scarcity affects everything from aioli for french fries to Caesar dressing and Chick-fil-A sauce.

The situation has even led to unusual law enforcement activities, with border patrol agents confiscating smuggled eggs as price differences create incentives for black market trade.

Looking Forward

As the bird flu situation continues to evolve, Americans face continued uncertainty about egg prices and availability. The administration's ability to effectively address both the agricultural crisis and its economic fallout may significantly influence public perception of its competence in managing domestic affairs.

For consumers, adaptation remains the immediate response—whether through finding egg alternatives, adjusting recipes, or simply paying premium prices for this once-affordable protein source that has become, decidedly, no longer cheaper by the dozen.

Unraveling Change: How Small Sustainability Efforts Can Transform the Textile Industry

So far, there aren’t many studies that connect small, specific projects with large-scale global systems or examine how different levels and processes interact. This paper uses a leverage points framework to explore how systems can be transformed. It looks at four sustainability efforts in the textile industry and examines how they fit into a larger network of connected systems. It also considers how these connections influence the ability of these efforts to create real change.

Building for a Hotter Future: Smart Design Solutions to Cut Building Energy Use, Particularly in the Global South

Buildings in hot climate zones face unique challenges in reducing energy use and CO₂ emissions, especially as urbanization and population growth drive new construction. This study examines how different design choices and technologies can help make buildings more energy-efficient while keeping them comfortable in high temperatures. Using computer simulations, the researchers tested five building types—ranging from homes to offices—across five hot climate regions. They explored a mix of passive design strategies (like better windows, reflective roofs, and solar shading), active cooling systems, and renewable energy options to see which solutions had the greatest impact.

The results show that simple changes, such as improving windows and adding shading, can significantly reduce cooling needs. More advanced systems, like hybrid ventilation and decentralized cooling units, further improve efficiency, while solar energy solutions help offset electricity use. The study also found that climate change will increase cooling demand in the future, making energy-efficient design even more critical. Notably, residential buildings had the greatest potential for achieving low-carbon or even zero-carbon status, while offices and hotels posed greater challenges due to their higher energy use.

To turn these insights into action, the study highlights the need for stronger policies and building codes, particularly in the Global South, where energy-efficient design is less widely implemented. The findings provide a roadmap for decision-makers to develop strategies that balance affordability with sustainability. By combining modern technology with lessons from traditional architecture, buildings in hot climates can become more efficient, reducing emissions while improving comfort and resilience in a warming world.

Discovering the Secret Life of Solids: Catching Materials Evolution in Real Time

Metal halide perovskites are remarkable materials with the ability to convert sunlight into electricity, emit colorful light, and detect radiation. However, making them typically requires harmful solvents, and the process of their formation has remained largely invisible to scientists. To address this, researchers combined an old technique—mechanochemistry, which involves grinding solids to trigger chemical reactions—with modern optical spectroscopy. By replacing traditional milling jars with transparent quartz and using a Time-Lapsed In Situ (TLIS) spectrometer, they created a system that allows scientists to observe perovskite formation in real-time, capturing every millisecond of change. This new tool acts like a high-speed camera for materials, revealing how disordered solid precursors evolve into structured, functional crystals.

Figure 1: The TLIS Spectrometer and Its Applications, see description below.


Using the TLIS spectrometer, the team made several key discoveries. They observed how a promising solar cell material, formamidinium lead triiodide (FAPbI₃), quickly degrades from a stable black phase to an ineffective yellow phase, but adding methylammonium (MA⁺) helped slow this process significantly. In another case, a lead-free perovskite unexpectedly "self-healed" over the weekend, improving its ability to emit light due to the slow migration of chloride ions within the solid. They also enhanced tin-based perovskites, which are more environmentally friendly than lead-based ones but degrade quickly, by creating a protective chloride shell. This breakthrough not only improves stability but also opens new possibilities for biomedical imaging. The ability to observe materials evolving in real time allows scientists to develop and optimize new materials much faster, reducing research time from months to days while eliminating the need for hazardous solvents. This work paves the way for more sustainable, efficient material discovery across industries like solar energy, electronics, and even food science.

What is (and isn’t) Endemic Innovation?

Endemic Innovation (EI) is a way of creating solutions that are deeply connected to a specific region’s unique resources, traditions, and knowledge. Unlike traditional innovation, which focuses on making things scalable for a global market, EI starts locally—using what already exists in a place to solve problems in a sustainable and effective way. For example, Portugal’s Amorim Cork company uses the country’s natural cork forests and traditional harvesting techniques to produce high-tech materials for industries like aerospace. Similarly, Iceland’s ON Power turns volcanic heat into clean energy, while New Zealand’s Comvita builds on Māori knowledge to produce medical-grade Manuka honey. True EI must meet five key criteria: it must rely on endemic (unique and non-replicable) resources or knowledge, be sustainable, be deeply connected to local communities, combine local and global technologies, and have the potential for global impact.


However, not every local project counts as EI. Simply being a grassroots initiative or having local value doesn’t make something an example of EI unless it meets the strict criteria. For instance, Israel’s Netafim developed drip irrigation to solve water scarcity in the Negev Desert, but its technology was designed to be adapted worldwide. Similarly, Chile’s Spora transforms fungi from its native forests into sustainable fashion, combining ancient knowledge with cutting-edge biotechnology. The core idea of EI is not just preserving tradition but evolving it—blending old knowledge with modern advancements to create sustainable, high-impact solutions. As climate change and global challenges increase, EI offers a new way forward, proving that the best solutions often come from the unique strengths of a place rather than one-size-fits-all approaches.

Asteroid Bennu’s Secrets: Clues to Life’s Building Blocks in Space

NASA’s OSIRIS-REx mission collected samples from asteroid Bennu and found important building blocks of life. Scientists discovered:

  • 14 of the 20 amino acids that make up proteins in living things.
  • All five pieces of DNA and RNA.
  • Lots of ammonia and other important chemicals for life.
  • Special salts that suggest Bennu’s parent asteroid once had liquid water.
This special scan of a tiny grain from Bennu’s surface shows where salty deposits sit on top of clay. The colors represent different elements: phosphorus (green), calcium (red), iron (yellow), and magnesium (blue). A very thin line of magnesium sodium phosphate (the green spot in the center) formed when water evaporated. This phosphate might have helped create some of the important organic molecules found in the sample.


These findings don’t mean life existed on Bennu, but they do show that the early solar system had the right ingredients for life to form elsewhere.

One surprising discovery was that Bennu’s amino acids twist in both directions, unlike on Earth, where they mostly twist one way. This challenges earlier ideas about how life might have started here.

Scientists are keeping most of the samples safe for future study, hoping to learn even more about how life’s building blocks spread through space.

Moral Motivation and Social Influence in Decision-Making: A Theoretical Framework

This study introduces a theoretical model of decision-making that considers both moral values and social influence when people make choices. The key idea is that individuals must balance their personal interests with their sense of moral duty. The model assumes that moral motivation is not always strong on its own—it can be shaped by the actions of others. Specifically, moral obligation is made up of two parts: one that comes from within a person and another that is influenced by society. This framework helps explain common patterns seen in past research and offers a new way to understand economic behavior.

Refining Savage’s Representation Theorem: Axiomatic Comparisons and Historical Insights

Savage’s theorem is based on seven rules for making logical choices. This study clears up some confusion in past research about how different versions of these rules relate to each other. By doing this, it helps explain the current form of the theorem. The study also looks at how the theorem has changed over time and its historical development.

Some Notes on Savage’s Representation Theorem

On Savage's Representation Theorem

Savage’s Representation Theorem is a key result in decision theory that explains how rational choices can be modeled mathematically. It shows that if a person follows certain logical rules (axioms) when making decisions under uncertainty, then their choices can be represented as if they are maximizing expected utility—meaning they behave as if they are assigning probabilities to uncertain events and choosing the option that gives them the highest expected value.

Key Ideas of Savage’s Theorem:

  1. Rational Decision-Making: The theorem is built on seven axioms of rational choice, which describe how a person should behave if they are making consistent and reasonable decisions.
  2. Subjective Probability: Unlike traditional probability theory (where probabilities are given), Savage’s model allows people to form their own subjective probabilities based on their beliefs about uncertain events.
  3. Expected Utility: If a person follows these rational choice axioms, their decision-making can be explained by expected utility theory, meaning they act as if they are choosing the option with the highest weighted average payoff based on their beliefs.

Why is it Important?

  • It provides a foundation for modern decision theory and behavioral economics.
  • It explains how people can make choices in situations where probabilities are not given in advance (e.g., betting on the weather or investing in stocks).
  • It bridges probability theory and utility theory, shaping economic models of risk and uncertainty.

In simple terms, Savage’s theorem shows that if someone follows certain logical principles while making decisions, they can be seen as choosing based on their own beliefs about uncertainty and maximizing their expected benefits.

Chronological Choice and Preference Discovery: A Framework for Decision-Making Over Time

This study introduces a framework for analyzing decision-making when choices are made in a specific chronological order. It compares this approach to the traditional choice theory, which does not consider the timing of decisions, and examines other models that build on this standard framework. The study then applies this framework to explore different ways individuals discover their preferences. Using simple revealed preference tests, it identifies various models based on two key factors: (1) the prior beliefs individuals have about their options and (2) whether they make decisions step by step or consider future choices when making current decisions. The findings offer new ways to test how individuals learn and refine their preferences, distinguishing between those who focus only on the present and those who plan for the future.

Polarization, Hostility, and Spillover Effects in Conflict Dynamics

This study develops a simple conflict model with two players to examine how polarization and hostility evolve over time. It explores the effects of these factors on conflict intensity, possible outcomes, and the existence of stable equilibria. The findings indicate that without external influences (spillovers), the effort exerted in conflict depends on the ratio of effort productivity to initial polarization. However, when negative spillovers impact the conflict, stable equilibria may not exist. When spillovers influence outcomes, they can lead to multiple possible equilibria, including increased polarization and hostility. The analysis further examines how various factors—such as effort productivity, initial polarization, and the growth rates of polarization and hostility—affect conflict intensity and equilibrium outcomes. The results highlight the critical role of hostility, a factor often overlooked in conflict models. Finally, the study confirms that these findings remain valid even when only partial spillover effects are considered.

Fair Rewards in Crowdfunding: Balancing Contribution and Timing

The authors look at how to fairly reward people who contribute to a crowdfunded project. They create a model that isn’t based on strategy and introduce a new rule for rewards: a person’s reward depends on both how much money they give and when they give it. Using a method often used in sharing resources, they define this reward rule based on two simple fairness principles. The final rewards match a well-known idea from game theory called the Shapley value, which helps divide rewards fairly. Their rule also sends a clear message: if two people give the same amount, the one who donates earlier gets a bigger reward.

Quotes for February 6

Good morning, everyone! Well, good morning for me—it might be the middle of the night for some of you.

Today is February 6, 2025. It’s been a crazy week at work, and I haven’t been getting much sleep, but I’m hoping that changes soon.

This morning, I came across a bunch of quotes on my Reedwise feed. Since I forgot to check it yesterday (blame the hectic week!), I now have two days’ worth of quotes to share. I should probably write something more thoughtful today, but honestly, the lack of sleep isn’t helping my creativity.

Hope you’re all doing well!
