Non-Invasive Method to Estimate the Age of Fish
Scientists have developed a non-invasive method to estimate the age of fish using their DNA, specifically by tracking methylation patterns in age-related genes. This allows researchers to predict how fish populations will grow and aids in conservation efforts. Methuselah, an Australian lungfish residing in the California Academy of Sciences, was estimated to be around 92 years old, making her the oldest living aquarium fish. The epigenetic clock created by scientists provided insight into the potential lifespan of fish and their ability to adapt to changing environments.
The Challenge of Communicating with Aliens
The complexity of language presents a challenge in communicating with extraterrestrial civilizations. Language experts hypothesize that mathematical-based communication, rather than complex linguistic patterns, may be more universal and better suited for interstellar communication. Scientists have sent various messages into space using math and binary code, hoping for potential extraterrestrial contacts. However, the vast distances and time delays make communication with aliens a complex and uncertain endeavor. To better prepare for potential extraterrestrial communication, some linguists suggest studying animal communication and developing a deeper understanding of non-human languages.
Creating Robots from the Living Dead
Researchers have explored the concept of necrobotics, which involves using dead organisms to create robots. By studying a dead spider's hydraulic pressure system, mechanical engineers were able to create robotic claws that mimic a spider's gripping mechanism. This method of using dead spiders allows for soft robotics, which could have applications in medical surgery or search and rescue operations. Similar experiments have used taxidermy birds to create drones and muscle tissue from a dead mouse to power small robots. While the field of necrobotics is relatively new, it poses interesting possibilities for technological advancements.
Estimating the Age of Methuselah the Fish
Methuselah, an Australian lungfish at the California Academy of Sciences, has an estimated age of around 92 to 101 years old. Scientists developed a non-invasive method to estimate the age of fish using DNA analysis, specifically tracking methylation patterns in age-related genes. This method allows researchers to predict population growth and aid in conservation efforts without harming the fish. Methuselah, known as a living fossil, has outlived 231 other fish that arrived with her in 1938. Her longevity and uniqueness make her an iconic figure in the world of aquarium fish.
