People around the world celebrate Halloween on October 31, a holiday that has deep roots in the history of ancient cultures, originating from the Celtic Samhain festival. On this day, people would light fires and dress up in costumes to ward off evil spirits. As time evolved, Halloween became a symbol of terrifying creatures, such as witches and eerie animals like owls, bats, and snakes. In this article, we present the views of nine scientists who shed light on unconventional animals and plants that have inspired them, and what they wish the world knew about their favorite creatures. We will discuss common misconceptions surrounding these beings and how studying them can contribute to correcting the misunderstandings that surround them, opening new horizons for understanding biodiversity and the beauty of nature.
The Origins of Halloween and Its Current Status
Halloween is celebrated on October 31 each year, and its origin dates back to the ancient Samhain festival celebrated by the Celts. People at that time would light fires and don costumes as a means of warding off evil spirits. Over the years, this tradition evolved to include modern symbols like witches and ghosts, as well as animals often seen as eerie like crows, bats, owls, and snakes. These symbols embody the sense of fright and mystery that accompanies the Halloween celebration, allowing individuals to express hidden feelings or terrifying experiences in a safe environment.
In modern times, Halloween has become a social occasion celebrated in many countries, not just in the United States. Homes are adorned with lights and interactive decorations, and children wear frightening costumes in trick-or-treating rituals. Candy is distributed, and parties are held, making this holiday an emotional social gathering that goes beyond merely reviving ancient practices. Halloween allows individuals to enjoy an atmosphere of fun and absurdity, reflecting the human pursuit of experiencing strong emotions, whether they be fright or joy.
The Role of Crows in Scientific Research and Debunking Misconceptions
Based on recent research, crows have an unjust reputation, being considered undesirable birds associated with death and doom. However, research by Ivo Jacobs from Lund University in Sweden shows that these birds possess complex cognitive abilities similar to those found in primates. Although their brains are small, they demonstrate analytical capabilities such as problem-solving and the use of tools, debunking the notion that intelligence is confined to certain species.
Jacobs describes how crows compete to engage in research, viewing it as an entertaining process that enhances their intellectual abilities. He also reveals that many common misconceptions about crows are inaccurate. For example, it is believed they are attracted to shiny objects, but research has shown they prefer dull, round shapes. This reflects the depth of their behavior and interaction with their environment, calling for a reevaluation of the traditional stereotype surrounding them.
The Benefits of Bats from a Virology Perspective
Bats are an intriguing subject in the study of viruses, as they are a source of various infectious diseases. Linfa Wang from Duke University in Singapore is working to understand how bats resist dangerous viruses such as the Hendra virus and coronavirus. By studying the immune genome of these creatures, Wang aims to develop human treatments inspired by the immune properties of bats.
There is a prevailing tendency among people to blame bats for the outbreak of epidemics, but Wang clarifies that bats have coexisted with these viruses for thousands of years. A deep understanding of ecological balance and the impacts of human activities such as habitat destruction and wildlife trade is required. Wang’s efforts to engage the scientific community in educating about the positive role of bats can help change negative perceptions towards them.

Biology and Animal Models in Technological Research
The studies of biophysicist David Ho offer new dimensions for understanding movement and creative design. Ho demonstrates how animal languages, such as the tongues of cats or the shape of wombat feces, can inspire new designs for robots and complex materials. This requires studying the interactions of these animals in their natural environments and researching the materials used and how to apply them in modern technology.
The significance of these studies lies in how they provide solutions for improving the performance of robots in the face of changing and challenging environments. Although people may think that having a comprehensive knowledge of animal behavior is easy, the natural precedents and the complexity of movement suggest that there is much to learn. Learning about how animals move and succeed in their environments can lead to designing robots with greater flexibility and efficiency.
Utilizing Plants as Solutions to Environmental Problems
The study by Muyon Kao on cacti points to the innovations required in the field of water collection. Kao illustrates how the advanced mechanisms of plants, such as cactus spines, can help in gathering water from the environment, which is crucial for arid locations.
A device has been designed to collect fog that works like cactus spines to gather water from fog in dry environments. Kao’s work shows how environmental solutions can be inspired by nature, where biological developments reflect efficient systems that inspire technological advancement. It is important to research how to design these systems for application in various uninhabitable environments.
Reevaluating the Role of Wolves in the Ecosystem
Research by Dries Kwieb is reassessing the traditional understanding of wolves as dangerous creatures. With the increase of wolf populations in populated European areas, Kwieb shows that incidents of attacks on humans have not increased, indicating that wolves are not necessarily a threat. The importance of these studies lies in the role of wolves in maintaining the balance of the ecosystem by controlling prey populations, contributing to forest regeneration and biodiversity preservation.
Research in environments like the Białowieża Forest in Poland shows how wolves indirectly affect other plants and animals. By understanding these dynamics, wildlife management strategies can be developed more pluralistically and the importance of all living organisms in ecosystems can be understood.
Protecting Endangered Plant Diversity in Indonesia
Indonesia is home to a large number of endangered plants that require special attention from experts. Among these plants, the ghost orchid, scientifically known as Didymoplexis pallens, tops the priority list. This orchid is characterized by its faint and captivating appearance, as it grows in dense forest environments and completely lacks leaves and chlorophyll. These plants rely on their relationships with mycorrhizal fungi to obtain the necessary nutrients for survival. In recent years, its environment has seen a significant decline in bamboo litter, which is an important source of organic materials. This has directly led to the deterioration of ghost orchid populations, necessitating urgent measures for its preservation. Preserving these endangered species requires a deep understanding of their ecological role, as they are indicators of environmental status in their areas, relying on specific conditions like soil quality, moisture, and light amount. Fieldwork with students is part of initiatives aimed at building a community that cares about protecting plants by understanding their broader role in biodiversity conservation.
Natural Tricks of Plants in Attracting Pollinators
Unique plants, such as the corpse flower (Amorphophallus titanum), embody natural creativity in the plant world. This plant tends to attract pollinators by using bright colors and strong odors that resemble the scents emitted during human and animal diseases. This adaptation is intriguing as it indicates how these species have evolved to attract the right insects. In research, scientific teams aim to study the molecules associated with metabolism during human diseases to understand how this plant evolved to mimic odors. Recently, some researchers have pointed to the possibility of using this knowledge to develop new tools for diagnosing diseases based on smells. Collaboration between plant scientists, entomologists, and ecologists becomes essential, as it enriches the mutual understanding of how different species interact with each other and the effects on the ecosystem.
