Coming into 2026 I wanted to make a concerted effort to eat less dairy. Coming into Lent, I was curious to learn more about how religion has influenced one of my favorite vegan-friendly cuisines: Italian. Not all heavily Catholic countries lend themselves to plant-based diets, so I’m kicking off a Lenten exploration of culinary adaptations to religious limitations (and religious adaptations to culinary limitations).
Circadian rhythm can be disrupted by seasonal changes and travel across time zones. I often have trouble sleeping on a plane when my body thinks it’s the middle of the day, but several new technologies incorporated into the Boeing 787 Dreamliner help with those transitions. It was cool to see my body respond to subtle clues from the plane’s lighting and windows.
Just about one century ago, airships were rising to prominence as the luxury option for long-haul travel. Today, some companies are touting airships as a climate-friendly alternative to airplanes. We may be set to see a renaissance for this slower, more intentional means of travel, but we also need to consider unseen and upstream costs that can still contribute significantly to its carbon footprint.
Is it possible to reduce our resource consumption without abandoning a certain quality of life? The 2000 Watt Society thinks so. I first encountered this group in a near-term climate fiction novel following the lives of people trying to avoid the worst of climate change impacts. A recent trip to Switzerland showed me it can be done better than we’re doing it back home.
Giving up animal products entirely may not be a feasible option for many of us, but more people are eating less meat and cheese – and really making it count when they do. While I may never be a full vegan, it is important to me that I try to match my behaviors to my values, and that means eating less cheese more often.
For years I’ve incorrectly believed that sheep cheese has a lower carbon footprint than cow cheese because sheep emit far less methane than cows. They also produce far less milk, which balances the scales. In reality, cheese has an extremely high carbon footprint, higher than some meats. For that reason, it seemed like time to reevaluate whether my actions are still aligned with my values.
We use AI for countless tasks in our daily lives, but different activities have different carbon footprints. Analyzing and creating content uses a lot more energy than a simple internet search, and we’re relying on AI for more of that over time. That isn’t good for our brains or the environment, especially since we’re building more fossil fuel-powered data centers to meet growing demand.
Our search results shape how we view the world, and (with nearly 90% market share) Google shapes our search results. Data privacy has been a major criticism of Google for years, but the objectivity and accuracy of the results should be a concern too. With AI-generated overviews to take the place of doing our own research, we’re more susceptible than ever to groupthink.
The extra energy required for Artificial Intelligence to process pleasantries, such as “please” and “thank you,” apparently costs tens of millions of dollars, to say nothing of the environmental impact of generating that energy. Whether the query results are improved or the AI will deign to spare kind humans in the upcoming revolution, it seems there are some arguments in favor of being polite.
Physics, cooking, energy efficiency, and public health: so many of my passions are the ingredients of this blog post about our new induction cooktop. Magnetic induction cooking equipment has recently been getting cheaper, more accessible, and more popular, but it has long been safer, cleaner, and more energy efficient than the conventional alternatives, such as gas flames and electric coils.
