✨️🌌 I crafted this talisman myself back in 2006, the year I learned about my ADHD. Even before the diagnosis, I knew I was different. Due to my strong interest in nature, I had noticed parallels between myself and animals even before my diagnosis.

🐯 This is not a bad thing — indigenous cultures often seek their strength and abilities through a spiritual connection with animals. In fact, there is growing evidence suggesting that ADHD might have evolutionary roots, linked to traits that were advantageous in hunter-gatherer societies.

💀 This evolutionary mismatch hypothesis suggests that modern environmental factors, such as a sedentary lifestyle, mean that certain individuals are no longer optimally adapted, which may contribute to the difficulties we recognize as ADHD. Although this is still a hypothesis, I believe that in biology, nothing makes sense except in the light of evolution.

🤠 I have always felt a strong urge to explore nature, and there has never been anything more interesting to me than discovering. This intrinsic drive aligns well with behaviors observed in hunter-gatherer societies, where this knowledge is essential for survival. Animals, too, learn about their environment in similar ways.

🧬 I know that I inherited this passion for nature from my mother’s side, while my father is the one in whom I clearly see ADHD symptoms and behavior. My maternal grandfather also showed some ADHD characteristics.

🛖 When I consider that my closest circle of friends consists mostly of people with ADHD, it can be assumed that we have a similar interaction style, which probably also plays a role in our choice of partner.

🧫 Perhaps I am simply a unique combination of various prehistoric traits that complement each other.

🌱 Thus, it is understandable that I feel a strong connection to nature. This talisman represents value creation. The forked branch symbolizes creation, and the amber in between symbolizes value. Just as the branch splits and takes on a new shape, the amber was formed over time from resin.

Seeing in the Dark and the Green: How Eyes and Leaves Share a Lighty Secret

The world of biology reveals surprising connections, and the human eye and a seemingly ordinary leaf share a fascinating one. Both organs rely on sophisticated light-sensing mechanisms to function effectively in their environments, despite their vastly different purposes.

Within the human eye, the retina houses two crucial photoreceptor cell types: rods and cones. Rods, responsible for low-light vision, utilize rhodopsin, a specialized protein, to capture even the faintest light signals. Cones, responsible for color vision, rely on various forms of iodopsin to differentiate colors in bright light conditions. Both rhodopsin and iodopsin function by undergoing a shape change upon encountering light, triggering a biochemical cascade that ultimately translates light energy into electrical signals the brain interprets as vision.

Plants exhibit a similar strategy. Nestled within their leaves lies phytochrome, a remarkable molecule that, like its counterparts in the eye, acts as a light receptor. Phytochrome exists in several states depending on the specific wavelengths of light it absorbs. By sensing variations in light intensity and spectrum, phytochrome provides the plant with vital information about its surrounding environment. This information plays a critical role in processes like photosynthesis, where plants utilize sunlight as an energy source, and regulates growth patterns based on light availability.

In both the eye and the plant, the photosensors function together with chromophores: retinal in the eye and phytochromobilin in the plant.

This unexpected parallel between the human eye and the leaf underscores a fundamental principle in biology – the ability to detect light is a powerful evolutionary advantage. By harnessing the power of light, both humans and plants gain the ability to navigate their environments, grow, and thrive.

Last night, I discovered this early instar nymph of the cockroach Planuncus tingitanus s.l..🔦 It's a species complex which still needs much research. 🔬
Originally from the Mediterranean, they have spread rapidly in Europe in recent decades. In Germany, they were first found in Mainz in 2007. That's about 50 kilometers away from Oberursel. They live on shrubs near human settlements🌳🏘🏡 but only accidentally get into houses and only live outside.

Last night I photographed this small leafhopper (Jassargus sp.). Looking for tiny animals is fun, but in the darkness even more!
