The time I was least afraid of dying: I was 28-29. I was very recently divorced. I grew up in a religion that instilled a deep belief that family was everything, and failure in that domain was failure as a human, more or less. I'd resigned myself to the divorce after 6 years of marriage. I saw things in my future that were predictable and insubstantial. I realized during that time--a year or two--that I didn't really mind the thought that I might die.

I was not suicidal. I didn't want to die; in fact, I very much wanted to stay alive. At the same time, the thought that I might die wasn't weird or scary or unnerving. To be fair, I also still firmly believed in a relatively pleasant afterlife at that time.

I didn't take big risks. Didn't drive unsafely (any more than usual), didn't do daredevil stuff. I just didn't mind the thought of dying. I think about that, sometimes. If I ever get back to that zen-about-dying state again, it won't be for the same reasons, which had a big dose of religion in them.

How Do Periodical Cicadas Know When To Emerge?

"How do 17-year cicadas, which live underground as nymphs, track the passage of time so they all emerge synchronously as adults?"

In my new YouTube #video, I tell the #hypothetical story of a #Histiostomatidae #mite that lived its #lifehistory in the #dung heap of the #dinosaur #Edmontosaurus #annectens during the Late #Cretaceous. It developed #fungivorously within the dung and, when conditions deteriorated, was #transported by #flies to a new habitat (phoresis). All images and footage created with #AI assistance, except photos of free-living mites.

Why do songbirds sing in autumn?

Many songbirds sing in the autumn. If these birds aren’t breeding in the autumn, then why are they singing?

I ran across this picture of the most important person in my life and keep feeling all the feelings over it. We were 18, and she was helping me out with a class project, glamming herself up in a way that she didn't ordinarily do then to pose for this picture (the purpose of which I've forgotten).

All I can see is: we were so young, and she is so beautiful. And still is, an awful lot of years later.

Pink Flamingos Reveal Their Secret To Aging | study out of Tour du Valat, published by Proceedings of the National Academy of Sciences

"Migration has critical impacts on life trajectories by shaping mortality and reproductive outcomes. These findings are important for our knowledge on the biology of aging."

Today, on the 80th anniversary of WW2 Victory in Europe Day, I want to honor the memory of my grandfather, Alfred Christian Schram, who survived the horrors of Nazi-occupied Belgium as a teenager.

#30DayChartChallenge Día 16: Negative Relationship FOUND! 📉🐍🐦🐢🐟

¡Lo conseguimos! Tras ajustar por masa corporal, la relación entre Tasa Metabólica Específica (W/kg) y Longevidad Máxima (años) en ~530 especies animales (AnAge DB, outliers quitados) SÍ es negativa (Pearson ρ ≈ -0.42, p < 2.2e-16). #RelationshipsWeek #Animals

El gráfico log-log muestra la tendencia: mayor intensidad metabólica por kilo se asocia con vidas más cortas. ¡Apoya la idea del "ritmo de vida"! 🔥➡️⏳ Colores por Clase Taxonómica.

Un recordatorio de la importancia de normalizar variables y limpiar datos para ver la señal correcta. ¡Ciencia en acción!

#30DayChartChallenge Día 14: Kinship! 🌿 Hoy toca visualizar "parentescos" animales, pero basados en ¡similitud de rasgos! #RelationshipsWeek #Animals

Este dendrograma horizontal es el resultado de un clustering jerárquico (hclust Ward.D2) sobre ~170 especies, usando su Masa Corporal y Longevidad Máxima (log-transformadas y escaladas). ¡Muestra quién se agrupa con quién según su estrategia de vida!

Las ramas unen las especies más similares. La longitud horizontal hasta la unión indica cuán diferentes son. Se ven grandes grupos que separan, por ejemplo, animales muy grandes/longevos de otros más pequeños/rápidos. Es una forma de ver la estructura oculta en los datos de rasgos.

(Solo se muestra 1/3 de las etiquetas para no saturar!)

#30DayChartChallenge Día 13: Clusters Animales! 🐾 Explorando la relación Masa Corporal vs Longevidad Máxima. #RelationshipsWeek

Usando un dataset de Kaggle (+170 especies, ¡gracias S. Banerjee!) y tras una divertida limpieza de datos con rangos/unidades mixtas 😅, este scatter plot log-log revela patrones.

Coloreamos por Dieta: 🥩Carnívoro(verde) 🌿Herbívoro(ocre) ❓Omnívoro(azul).
Se ve la tendencia general (más grande = más longevo), pero los clústeres por dieta sugieren distintas **estrategias de historia de vida**. ¿Cómo gestionan su energía y longevidad según lo que comen? 🤔

¡Una visualización para explorar la alometría y la diversidad ecológica!

Long-distance migration can be dangerous. A life history model by Ronald C. Ydenberg predicts differences in over-summering between similar sandpiper species because the mortality posed by predators differs between flyways.
