Plants exhibit surprising survival mechanisms: The Venus fly trap counts seconds to ensure a meal, while the mimosa wilts to move away from threats, showcasing plants' natural intelligence and adaptability
Plants, such as the Venus fly trap and the mimosa, exhibit surprising sensitivity and intelligence in their survival mechanisms. The Venus fly trap, for instance, takes its time to open and close its traps, only doing so when it detects the presence of flies. It counts the number of seconds between successive touching of its hairs to ensure a meal is present before closing. The mimosa plant, on the other hand, reacts to touch by wilting, using water to move away from potential threats. Both plants employ these responses to enhance their chances of survival. The Venus fly trap's behavior can be seen as a computation, demonstrating a level of complexity and intelligence. Plants may not have the same capabilities as artificial intelligence, but their natural intelligence and adaptability continue to amaze scientists.

From dogs checking other doors to find the best way through, to plants reaching towards the light, to the smallest creatures executing amazing feats, every living thing exhibits some form of intelligence. This was emphasized by Greg Gage, a professor at the University of Michigan and co-founder of Backyard Brains. Even cells and things that come from cells are intelligent. Natural intelligence, or the study of how living organisms process information and respond to their environment, is inspiring computer scientists in designing the next generation of artificial intelligence. Creatures like African dung beetles, Sahara Desert ants, and honeybees have unique ways of navigating and solving problems, and understanding these natural processes can lead to innovative technological solutions. For instance, Francis Chance, a computational neuroscientist, researches how natural intelligence can help develop new security technology, such as missile defense systems learning from dragonflies' hunting techniques. So, the next time you observe a seemingly simple action in nature, remember that every living thing is an intelligent being in its own right.
Studying Dragonfly's Brain for Efficient AI: Researchers aim to build efficient AI by studying dragonflies' quick calculations to intercept prey, using computer models and experiments to identify responsible neurons and functions, potentially leading to low-power technology.
Researchers are studying the dragonfly's brain to understand how it makes quick calculations to intercept prey, with the goal of building efficient AI. Dragonflies perform coordinate transformations to adjust their flight path based on what they see, and their fast reaction time means they can only process information through a small neural circuit. Researchers are using computer models and experiments with living dragonflies to identify the neurons responsible for these calculations and understand their specific functions. The ultimate goal is to build computer chips that mimic the way the brain computes, potentially leading to more efficient technology like drones and navigation devices with extremely low power requirements.

The future of technology could hold devices that require minimal charging due to advancements in understanding how neurons use energy. This could lead to significant energy savings and a reduced carbon footprint. Neurons, like those in dragonflies, provide examples of intelligent solutions that operate efficiently with low power. In the realm of national defense, this could mean more efficient use of computer power for security missions. Our bodies also exhibit natural intelligence, and our immune systems, which use cytokines to fight off infections, can cause symptoms that are often mistakenly attributed to the virus or bacteria itself. Understanding these connections between our physical and mental health can provide new insights into the nature of intelligence and the potential for more efficient technology.
The immune system's impact on mood and social behavior: Our immune system influences mood and social behavior through cytokines, making us feel withdrawn when sick but motivating us to seek comfort and care in relationships
Our immune system plays a significant role in influencing our mood and social behavior through the production of cytokines. When we're sick, our bodies may send signals to our brains to make us feel depressed, withdrawn, and uninterested in socializing to conserve energy and allow our immune systems to function effectively. However, research also suggests that inflammation might motivate us to seek comfort and care from close relationships. This intricate relationship between our immune system and brain highlights the complexity of being human, as we possess the ability to override our immune system's signals with our prefrontal cortex. Ultimately, understanding this connection between inflammation and social behavior can provide valuable insights into human health and well-being.
Impact of Inflammation on Mood and Behavior: Inflammation, caused by various factors, can negatively impact mood and behavior, emphasizing the importance of addressing underlying causes for overall well-being.
