The scientific experiments were led by Leibniz Institute of Animal and Wildlife (Leibniz-IZW) and chaired by Professor Richard A. Holland (Bangor University, UK) and Dr. Gunārs P ē tersons (Latvia University of Life Sciences and Technology). It shows that now the cornea of ​​the eye is the site of an important sense in bat migration. A bat’s directional sense is its eyes. If the cornea is anesthetized, the otherwise reliable sense of orientation will be disturbed while the ability to detect light remains unaffected. The paper was published in the scientific journal Communications Biology. In the bats of one experimental group, the scientists locally anesthetized the cornea with a drop of oxybuprocaine. This surfactant is widely used in ophthalmology, where it is used to temporarily desensitize the cornea when the human or animal eye is over-irritated. However, an effect on orientation has not been noted before. In another experimental group of bats, the team anesthetized the cornea of ​​one eye. Individuals in the control group were not given anesthesia, but were instead given isotonic saline as eye drops. All animals in this scientific experiment were captured in a migratory corridor on the Baltic coast and released individually in the open field 11 km from the place of capture. First, the scientists used bat detectors to ensure that no other bats were in the field at the time of releasing the test animals. The direction of movement of the released bats was observed without knowing how the bats were treated experimentally. Dr. Oliver Lindecke, first author of the paper, explains: “The control group and the anesthetized group with unilateral corneas clearly oriented to the expected south, while the bats with corneas were anesthetized. both sides fly in random directions.” He added: “This clear difference in behavior suggests that corneal anesthesia has disrupted the sense of direction, but orientation seems to still work well with one eye. The corneal treatment wore off after a short time, and the bats were able to continue their journey south after the trial.” To rule out the possibility that an irritated cornea also affects visual sensation and that the scientists could therefore draw erroneous conclusions, they performed an additional test. Again, they examined whether the bats’ response to light changed after anesthetizing the corneas on one or both sides. “We know from previous research that bats prefer a illuminated exit when leaving a simple Y-shaped maze,” explains PD Dr Christian Voigt, head of the Leibniz-IZW Department of Evolutionary Ecology . “In our experiment, animals that were anesthetized either unilaterally or bilaterally also showed this preference; we can therefore rule out that light vision has been altered after corneal treatment. The ability to see light will of course also affect long-distance navigation. ” For instance, many vertebrates such as bats, dolphins, whales, fish and turtles can safely navigate in the dark, whether it’s under the open night sky, when it’s cloudy at night or in caves and tunnels as well as in the depths of the ocean. For decades, scientists have searched for a sense or a sensory organ that enables animals to perform navigational and orientation tasks that seemed unimaginable to humans. Magnetic sensation, so far only demonstrated in certain mammalian species. Experiments show that iron oxide particles in cells can act as “microcompass needles”, as is the case with some species of bacteria. The team’s experiments on Lindecke and Voigt provide for the first time reliable data for determining sensory orientation in migratory, free-migrating mammals. Exactly what a bat’s cornea looks like, how it works, and whether it is a long-sought magnetic sense need to be pointed out in future scientific investigations.

The bat’s sense of direction are the eyes. Mammals see with the eyes, hear with the ears, and smell with the nose. But which senses or organs allow them to direct their migration, sometimes beyond their feeding area and thus require extensive orientation? Scientific experiments led by the Leibniz Institute for Animal and Wildlife Research (Leibniz-IZW) led by Professor Richard A. Holland (Bangor University, UK) and Dr. Gunārs P ē tersons (Latvian University of Life Sciences and Technology). It shows that the cornea of ​​the eye is now an important sensory site for bat migration. If the cornea is anesthetized, another sense of reliable direction is disturbed while its ability to detect light remains unaffected. The article was published in the scientific journal Communications Biology. In the bats of an experimental group, the scientists localized the cornea with a drop of oxybuprocaine. This surface anesthetic is widely used in ophthalmology, where it is used to temporarily desensitize the cornea when the human or animal eye is overly irritated. However, the influence on the orientation has not been noted before. In another group of experimental bats, the team anesthetized the cornea of ​​one eye. Individuals in the control group received no anesthesia, but instead received an isotonic saline solution as eye drops.

After a short time the corneal treatment ended, the bats were able to resume their journey south after the test. ” To rule out the possibility that an irritated cornea also affects visual sensations and so scientists could have come to the wrong conclusion, they performed an additional test.

Light visibility will of course affect long-distance navigation as well. ” For example, many vertebrate species such as bats, dolphins, whales, fish and turtles can navigate safely in the dark, whether it is under the open night sky, when it is cloudy at night. or in caves and tunnels as well as in the depths of the ocean.

Super speed skateboard Appeared quite often in cartoons and theaters, however, in the comic book version, Conan rarely uses this treasure. Uncle Agasa created Conan’s super fast skateboard to help him chase down criminals. Designed to look like a normal skateboard, but the super powerful engine is built in so it can reach the speed of a race car in an emergency. The weak point of the skateboard is that it depends on solar energy, making it difficult to use at night. However, this disadvantage was overcome in the movie “The last wizard of the century” (1999) with improvements that can store energy for later use. Bubble Belts The use of the belt made by Professor Agasa is the ability to create a ball with the touch of a button, through which Conan can chase and control criminals. Many culprits were knocked down by the lightning kick from the detective without realizing what happened. Each cast only allows Conan 10 seconds to kick, so he must quickly catch the opportunity. Currently, the belt is designed with 3 options including ordinary ball, giant giant ball and fireworks ball, after a few seconds it will explode to create beautiful fireworks. Shoes increase strength According to Professor Agasa, the shoes use electricity and magnetic fields to stimulate Conan’s foot muscles allowing him to kick objects with tremendous force. This item is often combined with Conan with the ball to create lightning shots that can defeat heavy opponents. Before being equipped with a ball belt, Conan used these super powerful shoes to shoot into everything from buckets, helmets, baseball to cans. The shoes with shiny belts have made Conan a good pair of jewels, many times helped the kid detective group and friends out of danger. Anesthesia clock Disguised as a normal school watch, Conan’s watch actually hides a needle laced with anesthetic that can be shot at the person who needs to be lulled. The “victim” is mainly a zinc-bearded detective Mori, however there are times when Conan does not aim properly, so he shoots someone by mistake. After that, Conan will fake the voice of the sleeping person to solve the case, because normally, no one believes in a kid detective. Some of the other uses that he discovered during the use of anesthesia watches must be mentioned as neutralizing criminals, preventing others from committing crimes or protecting himself. Even Gin had been shot by Conan, but he responded by shooting himself in the hand to reduce the anesthetic effect of the drug. Eyeglasses The lens has been upgraded by Professor Agasa so Conan and Haibara can zoom in on distant targets and enhance visibility even in the dark. The glasses are used by Conan quite flexibly, sometimes tracking the super thief Kid, sometimes checking objects in the distance, other times looking for victims in the midst of a snowstorm. Depending on the comic or cartoon that Conan uses the left or right glasses, it is likely that Professor Agasa has upgraded both the glasses to make them easier to use. Crime tracking glasses Radar integrated in the glasses helps to locate the enemy’s coordinates within a radius of 20km. Those who are using the detective badge can also be tracked by these damn glasses. To activate the radar on the glass, the user can press a small button on the left-hand side. The glasses in some episodes also have a micro microphone that helps Conan hear secret conversations. Child detective badge Outwardly looking like an ordinary kid’s badge, the badges actually help Conan and the rest of the Detective Boys communicate from a distance, acting as a walkie-talkie. The badges also emit signaling that can be identified using crime tracking glasses. The tracking radar screen on the eyeglasses displays the child badges as dots. In the 18th film, these badges are upgraded by Professor Agasa so that the Child Detective Team can communicate at a long distance. Clock flashlight In addition to the anesthetic gun design, Conan’s wristwatch also incorporates a high-intensity flashlight capable of illuminating large areas in the dark. This helps the detective guy discover a suspicious clue without fear of ignoring anything. The collar changes the voice Professor Agasa designed this bracelet for Suichi Akai when he disguised as Subaru Okiya. Being disguised as someone else is not enough, Suichi knows that he also needs to change his voice so that the person facing him will not be suspicious. The necklace is cleverly designed to be hidden behind the shirt collar./.
