<p>Fritzi Buhtz: .mnbnlj</p> <hr /> <div>'''Project: Meet Marimo - ongoing Project''' <br /> <br /> In this experiment, we get to know Marimo. Through '''microscopic observation''', you can see that Marimos '''perform photosynthesis'''—they release tiny oxygen bubbles. Look closely—maybe you can spot them! <br /> <br /> At the '''smallest magnification''' under the microscope, you can observe individual structures of '''Aegagropila linnaei''': '''Algal filament cells''': Small, chain-like structures that form the dense network of the Marimo. '''Chloroplasts''': Tiny green organelles that capture light for photosynthesis—this is where oxygen is produced '''Oxygen bubbles''': Small, clear spheres attached to the algae filaments—visible proof of active photosynthesis. '''Bacteria or microorganisms''': Sometimes, you may see tiny life forms that live in '''symbiosis''' with the Marimo.<br /> <br /> Watch carefully—how do the bubbles change when you shine light on the Marimo?<br /> <br /> Short Discription: [[File:Marimo.jpg|thumb|659x659px]]Marimo balls are round green algae found in cool lakes in Japan, Iceland, Estonia, and Scotland, especially in Lake Akan, Japan. Their name comes from the Japanese words mari (ball) and mo (algae). They grow slowly, only 5 mm per year, and can reach 30 cm in size. <br /> <br /> Their soft, velvety texture and ability to roll with water currents help them thrive in low light and cold temperatures.      Marimos are symbols of luck and harmony in Japan, celebrated at the Marimo Festival. Beyond culture, they are natural water purifiers, absorbing pollutants and releasing oxygen. Scientists study them as biosensors to monitor water quality and as potential living machines for movement-based technology.                                                                                                                        <br /> <br /> Ecosystem Role &amp; Movement, Marimos help their environment by: <br /> <br /> Producing oxygen through photosynthesis, benefiting fish and aquatic plants.                              <br /> <br /> Filtering water, removing pollutants, and maintaining balance. Providing shelter for tiny organisms. They float when oxygen bubbles form and sink when photosynthesis stops or water is stirred.  Pollution and tourism threaten Marimo populations. Conservation efforts in Lake Akan work to protect their habitats and ensure their survival.<br /> [[File:48a0369748be0a6ee374a79390663e07.jpg|thumb]]<br /> [[File:Th.jpg|thumb|303x303px]]<br /> [[File:LX8TZIjA.jpg|thumb|579x579px]]<br /> Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors.<br /> <br /> [[File:Marimo microscope.jpg|thumb|687x687px]]<br /> [[File:6FFCCWTw.jpg|thumb]][[File:Photo 2025-02-25 23-51-45.jpg|thumb]]<br /> <br /> <br /> <br /> <br /> <br /> <br /> === Biography of Marimo Balls: The Fascinating World of Living Algae Spheres ===<br /> Birthplace and Origin:<br /> <br /> Marimo balls, also known as Cladophora balls, originate from clear, cool lakes in regions such as Japan, Iceland, Estonia, and Scotland. They are particularly famous in Japan, where they are found in Lake Akan on the island of Hokkaido. The name &quot;Marimo&quot; combines the Japanese words mari (ball) and mo (algae).<br /> <br /> Lifestyle and Characteristics:<br /> <br /> Marimo balls are composed of filaments of the green algae Aegagropila linnaei. The species Aegagropila linnaei belongs to the green algae family, which evolved over 1 billion years ago. Green algae were among the earliest photosynthetic organisms on Earth, contributing to the planet's oxygenation and forming the basis for plant evolution.             Their spherical structure is formed through a combination of gentle water currents and their ability to self-shape. They grow slowly, often only 5 millimeters per year, and can reach impressive sizes of up to 30 centimeters. Marimos have a vibrant green color and a soft, velvety surface.<br /> <br /> These algae are true survivors, capable of thriving in various water conditions thanks to their adaptation to low temperatures and limited light. They are also light-sensitive and roll in response to sunlight to ensure even exposure, a fascinating example of plant-like movement.<br /> <br /> Symbolism and Cultural Significance:<br /> <br /> In Japan, Marimo balls are considered good luck charms and symbols of purity, harmony, and connection to nature. An annual Marimo Festival is held at Lake Akan to celebrate these algae as a national treasure. They are also popular as low-maintenance pets in aquariums. The belief that Marimos can &quot;preserve love and wishes&quot; makes them a meaningful gift.<br /> <br /> Scientific Importance:<br /> <br /> Beyond their cultural role, Marimo balls have drawn attention in scientific research. Their unique structure and sensitivity to environmental conditions make them natural indicators of water quality. Researchers are exploring their potential as biosensors to monitor changes in pH levels, oxygen content, or pollutants. They also show promise as living machines, potentially being integrated into technologies for oscillators or actuators.<br /> <br /> Challenges and Conservation:<br /> <br /> Despite their resilience, Marimo balls are threatened by human activities such as pollution and tourism. The habitats of many natural populations have diminished. Conservation programs, such as those at Lake Akan, aim to preserve their environment and promote the natural reproduction of these algae.<br /> <br /> <br /> <br /> &lt;u&gt;Relationship with Water Ecosystems&lt;/u&gt;<br /> <br /> Marimo balls thrive in freshwater lakes, where their survival depends on the dynamic balance of light, temperature, nutrients, and water movement. <br /> <br /> In return, they contribute to the ecosystem by:<br /> <br /> - Providing Oxygen: Through photosynthesis, Marimos release oxygen into the water, supporting aquatic life. This benefits other organisms like fish and smaller aquatic plants.<br /> <br /> - Filtering the Environment: They absorb nutrients and pollutants from the water, helping maintain a cleaner, more balanced ecosystem.<br /> <br /> <br /> [[File:Pap-ihoA.jpg|thumb|[[File:Ohne Titel.mov|thumb|0x0px]]|353x353px]]&lt;u&gt;Interaction with Watercurrents&lt;/u&gt;<br /> <br /> Water currents play a crucial role in shaping Marimo balls into their distinctive spherical form. This interaction benefits the algae by:<br /> <br /> - Ensuring even light exposure for photosynthesis.<br /> <br /> - Preventing sediment accumulation on their surface, which would block light and hinder growth. In turn, the algae ball adapts to the currents, rolling and growing symmetrically, demonstrating a cooperative relationship with its physical environment.<br /> <br /> <br /> <br /> &lt;u&gt;Microhabitat Provider&lt;/u&gt;<br /> <br /> The dense structure of Marimo balls can serve as a mini-ecosystem for microorganisms and small aquatic creatures:<br /> <br /> - Tiny organisms like plankton and microorganisms can shelter within the Marimo ball's filament network.<br /> <br /> - This mutualistic relationship allows the algae to recycle nutrients from the waste or activities of these inhabitants.<br /> <br /> Marimo balls perform photosynthesis when exposed to light, producing oxygen that accumulates in tiny bubbles on their surface.<br /> <br /> - Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy.<br /> <br /> - Sinking: In darkness (e.g., at night), photosynthesis stops, the oxygen diffuses into the water, and the Marimo ball becomes heavier, causing it to sink.<br /> <br /> - Movement supports sinking: If the water is stirred (e.g., by waves or pumps), it can help release trapped oxygen bubbles, causing the Marimo to sink again.<br /> <br /> [[File:Photo 2025-02-25 23-50-27.jpg|thumb|543x543px]]<br /> <br /> &lt;u&gt;Marimo Balls: A Natural and Ecological Alternative to Synthetic Sensors&lt;/u&gt;<br /> <br /> Researchers have leveraged these properties to explore the potential of Marimo balls as small, living sensors. They investigated three possible applications:<br /> <br /> - Oscillators: Marimo balls could create regular, rhythmic movements similar to a pendulum by influencing their growth or movement patterns.<br /> <br /> - Biosensors: They could monitor environmental changes, such as water quality, based on their behavior and growth.<br /> <br /> - Actuators: Marimo balls could perform actions in response to signals, such as changing position or activating small devices.<br /> <br /> In comparison, synthetic chemical sensors are based on artificial materials and technologies that detect specific chemicals or changes in the chemical environment. They consist of a sensing material that reacts with the target chemical, a transducer that converts this reaction into an electronic signal, and a processing unit that displays the results. <br /> <br /> There are various types of such sensors, including gas sensors, which detect gases like oxygen or methane; ion sensors, which measure specific ions in liquids; and optical sensors, which detect changes in light caused by chemical reactions. A subset of these sensors are biosensors, which combine synthetic components with biological elements.<br /> <br /> Synthetic chemical sensors offer high sensitivity, fast and accurate measurements, and are often compact and easy to integrate. However, they are often expensive, have a limited lifespan, and sometimes use non-biodegradable materials. In contrast, living biosensors like Marimo balls utilize biological reactions as their mechanism and provide a more environmentally friendly and sustainable alternative for many applications. This research demonstrates how Marimo balls could offer an innovative way to monitor ecosystems while preserving the environment.[[File:Meet Marimo- The Guardians of Lake Akan.wav|thumb|Audio Story- MEET MARIMO]][[File:Photo 2025-02-26 00-06-56.jpg|thumb|561x561px]]- They grow naturally, requiring no complex manufacturing.<br /> <br /> - They act as ecological filters, absorbing impurities and contributing to water health. <br /> <br /> In the exibithion the project included an interactive, sensory exploration of Marimo balls.

<p>Fritzi Buhtz: zgfkhg</p> <hr /> <div>Project: Meet Marimo <br /> <br /> In this experiment, we get to know Marimo. Through '''microscopic observation''', you can see that Marimos '''perform photosynthesis'''—they release tiny oxygen bubbles. Look closely—maybe you can spot them! <br /> <br /> At the '''smallest magnification''' under the microscope, you can observe individual structures of '''Aegagropila linnaei''': '''Algal filament cells''': Small, chain-like structures that form the dense network of the Marimo. '''Chloroplasts''': Tiny green organelles that capture light for photosynthesis—this is where oxygen is produced '''Oxygen bubbles''': Small, clear spheres attached to the algae filaments—visible proof of active photosynthesis. '''Bacteria or microorganisms''': Sometimes, you may see tiny life forms that live in '''symbiosis''' with the Marimo.<br /> <br /> Watch carefully—how do the bubbles change when you shine light on the Marimo?<br /> <br /> Short Discription: [[File:Marimo.jpg|thumb|659x659px]]Marimo balls are round green algae found in cool lakes in Japan, Iceland, Estonia, and Scotland, especially in Lake Akan, Japan. Their name comes from the Japanese words mari (ball) and mo (algae). They grow slowly, only 5 mm per year, and can reach 30 cm in size. <br /> <br /> Their soft, velvety texture and ability to roll with water currents help them thrive in low light and cold temperatures.      Marimos are symbols of luck and harmony in Japan, celebrated at the Marimo Festival. Beyond culture, they are natural water purifiers, absorbing pollutants and releasing oxygen. Scientists study them as biosensors to monitor water quality and as potential living machines for movement-based technology.                                                                                                                        <br /> <br /> Ecosystem Role &amp; Movement, Marimos help their environment by: <br /> <br /> Producing oxygen through photosynthesis, benefiting fish and aquatic plants.                              <br /> <br /> Filtering water, removing pollutants, and maintaining balance. Providing shelter for tiny organisms. They float when oxygen bubbles form and sink when photosynthesis stops or water is stirred.  Pollution and tourism threaten Marimo populations. Conservation efforts in Lake Akan work to protect their habitats and ensure their survival.<br /> [[File:48a0369748be0a6ee374a79390663e07.jpg|thumb]]<br /> [[File:Th.jpg|thumb|303x303px]]<br /> [[File:LX8TZIjA.jpg|thumb|579x579px]]<br /> [[File:Pap-ihoA.jpg|thumb|[[File:Ohne Titel.mov|thumb|0x0px]]|353x353px]]<br /> Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors.<br /> <br /> [[File:Marimo microscope.jpg|thumb|687x687px]]<br /> [[File:6FFCCWTw.jpg|thumb]][[File:Photo 2025-02-25 23-51-45.jpg|thumb]]<br /> <br /> <br /> <br /> <br /> <br /> <br /> === Biography of Marimo Balls: The Fascinating World of Living Algae Spheres ===<br /> Birthplace and Origin:<br /> <br /> Marimo balls, also known as Cladophora balls, originate from clear, cool lakes in regions such as Japan, Iceland, Estonia, and Scotland. They are particularly famous in Japan, where they are found in Lake Akan on the island of Hokkaido. The name &quot;Marimo&quot; combines the Japanese words mari (ball) and mo (algae).<br /> <br /> Lifestyle and Characteristics:<br /> <br /> Marimo balls are composed of filaments of the green algae Aegagropila linnaei. The species Aegagropila linnaei belongs to the green algae family, which evolved over 1 billion years ago. Green algae were among the earliest photosynthetic organisms on Earth, contributing to the planet's oxygenation and forming the basis for plant evolution.             Their spherical structure is formed through a combination of gentle water currents and their ability to self-shape. They grow slowly, often only 5 millimeters per year, and can reach impressive sizes of up to 30 centimeters. Marimos have a vibrant green color and a soft, velvety surface.<br /> <br /> These algae are true survivors, capable of thriving in various water conditions thanks to their adaptation to low temperatures and limited light. They are also light-sensitive and roll in response to sunlight to ensure even exposure, a fascinating example of plant-like movement.<br /> <br /> Symbolism and Cultural Significance:<br /> <br /> In Japan, Marimo balls are considered good luck charms and symbols of purity, harmony, and connection to nature. An annual Marimo Festival is held at Lake Akan to celebrate these algae as a national treasure. They are also popular as low-maintenance pets in aquariums. The belief that Marimos can &quot;preserve love and wishes&quot; makes them a meaningful gift.<br /> <br /> Scientific Importance:<br /> <br /> Beyond their cultural role, Marimo balls have drawn attention in scientific research. Their unique structure and sensitivity to environmental conditions make them natural indicators of water quality. Researchers are exploring their potential as biosensors to monitor changes in pH levels, oxygen content, or pollutants. They also show promise as living machines, potentially being integrated into technologies for oscillators or actuators.<br /> <br /> Challenges and Conservation:<br /> <br /> Despite their resilience, Marimo balls are threatened by human activities such as pollution and tourism. The habitats of many natural populations have diminished. Conservation programs, such as those at Lake Akan, aim to preserve their environment and promote the natural reproduction of these algae.<br /> <br /> <br /> <br /> &lt;u&gt;Relationship with Water Ecosystems&lt;/u&gt;<br /> <br /> Marimo balls thrive in freshwater lakes, where their survival depends on the dynamic balance of light, temperature, nutrients, and water movement. <br /> <br /> In return, they contribute to the ecosystem by:<br /> <br /> - Providing Oxygen: Through photosynthesis, Marimos release oxygen into the water, supporting aquatic life. This benefits other organisms like fish and smaller aquatic plants.<br /> <br /> - Filtering the Environment: They absorb nutrients and pollutants from the water, helping maintain a cleaner, more balanced ecosystem.<br /> <br /> <br /> <br /> &lt;u&gt;Interaction with Watercurrents&lt;/u&gt;<br /> <br /> Water currents play a crucial role in shaping Marimo balls into their distinctive spherical form. This interaction benefits the algae by:<br /> <br /> - Ensuring even light exposure for photosynthesis.<br /> <br /> - Preventing sediment accumulation on their surface, which would block light and hinder growth. In turn, the algae ball adapts to the currents, rolling and growing symmetrically, demonstrating a cooperative relationship with its physical environment.<br /> <br /> <br /> <br /> &lt;u&gt;Microhabitat Provider&lt;/u&gt;<br /> <br /> The dense structure of Marimo balls can serve as a mini-ecosystem for microorganisms and small aquatic creatures:<br /> <br /> - Tiny organisms like plankton and microorganisms can shelter within the Marimo ball's filament network.<br /> <br /> - This mutualistic relationship allows the algae to recycle nutrients from the waste or activities of these inhabitants.<br /> <br /> Marimo balls perform photosynthesis when exposed to light, producing oxygen that accumulates in tiny bubbles on their surface.<br /> <br /> - Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy.<br /> <br /> - Sinking: In darkness (e.g., at night), photosynthesis stops, the oxygen diffuses into the water, and the Marimo ball becomes heavier, causing it to sink.<br /> <br /> - Movement supports sinking: If the water is stirred (e.g., by waves or pumps), it can help release trapped oxygen bubbles, causing the Marimo to sink again.<br /> <br /> [[File:Photo 2025-02-25 23-50-27.jpg|thumb|543x543px]]<br /> <br /> &lt;u&gt;Marimo Balls: A Natural and Ecological Alternative to Synthetic Sensors&lt;/u&gt;<br /> <br /> Researchers have leveraged these properties to explore the potential of Marimo balls as small, living sensors. They investigated three possible applications:<br /> <br /> - Oscillators: Marimo balls could create regular, rhythmic movements similar to a pendulum by influencing their growth or movement patterns.<br /> <br /> - Biosensors: They could monitor environmental changes, such as water quality, based on their behavior and growth.<br /> <br /> - Actuators: Marimo balls could perform actions in response to signals, such as changing position or activating small devices.<br /> <br /> In comparison, synthetic chemical sensors are based on artificial materials and technologies that detect specific chemicals or changes in the chemical environment. They consist of a sensing material that reacts with the target chemical, a transducer that converts this reaction into an electronic signal, and a processing unit that displays the results. <br /> <br /> There are various types of such sensors, including gas sensors, which detect gases like oxygen or methane; ion sensors, which measure specific ions in liquids; and optical sensors, which detect changes in light caused by chemical reactions. A subset of these sensors are biosensors, which combine synthetic components with biological elements.<br /> <br /> <br /> <br /> Synthetic chemical sensors offer high sensitivity, fast and accurate measurements, and are often compact and easy to integrate. However, they are often expensive, have a limited lifespan, and sometimes use non-biodegradable materials. In contrast, living biosensors like Marimo balls utilize biological reactions as their mechanism and provide a more environmentally friendly and sustainable alternative for many applications. This research demonstrates how Marimo balls could offer an innovative way to monitor ecosystems while preserving the environment.[[File:Meet Marimo- The Guardians of Lake Akan.wav|thumb|Audio Story- MEET MARIMO]][[File:Photo 2025-02-26 00-06-56.jpg|thumb|561x561px]]- They grow naturally, requiring no complex manufacturing.<br /> <br /> - They act as ecological filters, absorbing impurities and contributing to water health. <br /> <br /> In the exibithion the project included an interactive, sensory exploration of Marimo balls.

<p>Fritzi Buhtz: hgfjgf</p> <hr /> <div>Project: Meet Marimo <br /> <br /> In this experiment, we get to know Marimo. Through '''microscopic observation''', you can see that Marimos '''perform photosynthesis'''—they release tiny oxygen bubbles. Look closely—maybe you can spot them! <br /> <br /> At the '''smallest magnification''' under the microscope, you can observe individual structures of '''Aegagropila linnaei''': '''Algal filament cells''': Small, chain-like structures that form the dense network of the Marimo. '''Chloroplasts''': Tiny green organelles that capture light for photosynthesis—this is where oxygen is produced '''Oxygen bubbles''': Small, clear spheres attached to the algae filaments—visible proof of active photosynthesis. '''Bacteria or microorganisms''': Sometimes, you may see tiny life forms that live in '''symbiosis''' with the Marimo.<br /> <br /> Watch carefully—how do the bubbles change when you shine light on the Marimo?<br /> <br /> Short Discription: [[File:Marimo.jpg|thumb|659x659px]]Marimo balls are round green algae found in cool lakes in Japan, Iceland, Estonia, and Scotland, especially in Lake Akan, Japan. Their name comes from the Japanese words mari (ball) and mo (algae). They grow slowly, only 5 mm per year, and can reach 30 cm in size. <br /> <br /> Their soft, velvety texture and ability to roll with water currents help them thrive in low light and cold temperatures.      Marimos are symbols of luck and harmony in Japan, celebrated at the Marimo Festival. Beyond culture, they are natural water purifiers, absorbing pollutants and releasing oxygen. Scientists study them as biosensors to monitor water quality and as potential living machines for movement-based technology.                                                                                                                        <br /> <br /> Ecosystem Role &amp; Movement, Marimos help their environment by: <br /> <br /> Producing oxygen through photosynthesis, benefiting fish and aquatic plants.                              <br /> <br /> Filtering water, removing pollutants, and maintaining balance. Providing shelter for tiny organisms. They float when oxygen bubbles form and sink when photosynthesis stops or water is stirred.  Pollution and tourism threaten Marimo populations. Conservation efforts in Lake Akan work to protect their habitats and ensure their survival.<br /> [[File:48a0369748be0a6ee374a79390663e07.jpg|thumb]]<br /> [[File:Th.jpg|thumb|303x303px]]<br /> [[File:LX8TZIjA.jpg|thumb|579x579px]]<br /> [[File:Pap-ihoA.jpg|thumb|[[File:Ohne Titel.mov|thumb|0x0px]]]]<br /> Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors.<br /> <br /> [[File:Marimo microscope.jpg|thumb|687x687px]]<br /> [[File:6FFCCWTw.jpg|thumb]][[File:Photo 2025-02-25 23-51-45.jpg|thumb]]<br /> <br /> <br /> <br /> <br /> <br /> <br /> === Biography of Marimo Balls: The Fascinating World of Living Algae Spheres ===<br /> Birthplace and Origin:<br /> <br /> Marimo balls, also known as Cladophora balls, originate from clear, cool lakes in regions such as Japan, Iceland, Estonia, and Scotland. They are particularly famous in Japan, where they are found in Lake Akan on the island of Hokkaido. The name &quot;Marimo&quot; combines the Japanese words mari (ball) and mo (algae).<br /> <br /> Lifestyle and Characteristics:<br /> <br /> Marimo balls are composed of filaments of the green algae Aegagropila linnaei. The species Aegagropila linnaei belongs to the green algae family, which evolved over 1 billion years ago. Green algae were among the earliest photosynthetic organisms on Earth, contributing to the planet's oxygenation and forming the basis for plant evolution.             Their spherical structure is formed through a combination of gentle water currents and their ability to self-shape. They grow slowly, often only 5 millimeters per year, and can reach impressive sizes of up to 30 centimeters. Marimos have a vibrant green color and a soft, velvety surface.<br /> <br /> These algae are true survivors, capable of thriving in various water conditions thanks to their adaptation to low temperatures and limited light. They are also light-sensitive and roll in response to sunlight to ensure even exposure, a fascinating example of plant-like movement.<br /> <br /> Symbolism and Cultural Significance:<br /> <br /> In Japan, Marimo balls are considered good luck charms and symbols of purity, harmony, and connection to nature. An annual Marimo Festival is held at Lake Akan to celebrate these algae as a national treasure. They are also popular as low-maintenance pets in aquariums. The belief that Marimos can &quot;preserve love and wishes&quot; makes them a meaningful gift.<br /> <br /> Scientific Importance:<br /> <br /> Beyond their cultural role, Marimo balls have drawn attention in scientific research. Their unique structure and sensitivity to environmental conditions make them natural indicators of water quality. Researchers are exploring their potential as biosensors to monitor changes in pH levels, oxygen content, or pollutants. They also show promise as living machines, potentially being integrated into technologies for oscillators or actuators.<br /> <br /> Challenges and Conservation:<br /> <br /> Despite their resilience, Marimo balls are threatened by human activities such as pollution and tourism. The habitats of many natural populations have diminished. Conservation programs, such as those at Lake Akan, aim to preserve their environment and promote the natural reproduction of these algae.<br /> <br /> <br /> <br /> &lt;u&gt;Relationship with Water Ecosystems&lt;/u&gt;<br /> <br /> Marimo balls thrive in freshwater lakes, where their survival depends on the dynamic balance of light, temperature, nutrients, and water movement. In return, they contribute to the ecosystem by:<br /> <br /> - Providing Oxygen: Through photosynthesis, Marimos release oxygen into the water, supporting aquatic life. This benefits other organisms like fish and smaller aquatic plants.<br /> <br /> - Filtering the Environment: They absorb nutrients and pollutants from the water, helping maintain a cleaner, more balanced ecosystem.<br /> <br /> <br /> <br /> &lt;u&gt;Interaction with Watercurrents&lt;/u&gt;<br /> <br /> Water currents play a crucial role in shaping Marimo balls into their distinctive spherical form. This interaction benefits the algae by:<br /> <br /> - Ensuring even light exposure for photosynthesis.<br /> <br /> - Preventing sediment accumulation on their surface, which would block light and hinder growth. In turn, the algae ball adapts to the currents, rolling and growing symmetrically, demonstrating a cooperative relationship with its physical environment.<br /> <br /> <br /> <br /> &lt;u&gt;Microhabitat Provider&lt;/u&gt;<br /> <br /> The dense structure of Marimo balls can serve as a mini-ecosystem for microorganisms and small aquatic creatures:<br /> <br /> - Tiny organisms like plankton and microorganisms can shelter within the Marimo ball's filament network.<br /> <br /> - This mutualistic relationship allows the algae to recycle nutrients from the waste or activities of these inhabitants.<br /> <br /> Marimo balls perform photosynthesis when exposed to light, producing oxygen that accumulates in tiny bubbles on their surface.<br /> <br /> - Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy.<br /> <br /> - Sinking: In darkness (e.g., at night), photosynthesis stops, the oxygen diffuses into the water, and the Marimo ball becomes heavier, causing it to sink.<br /> <br /> - Movement supports sinking: If the water is stirred (e.g., by waves or pumps), it can help release trapped oxygen bubbles, causing the Marimo to sink again.<br /> <br /> [[File:Photo 2025-02-25 23-50-27.jpg|thumb|543x543px]]<br /> <br /> &lt;u&gt;Marimo Balls: A Natural and Ecological Alternative to Synthetic Sensors&lt;/u&gt;<br /> <br /> Researchers have leveraged these properties to explore the potential of Marimo balls as small, living sensors.

<p>Fritzi Buhtz: </p> <hr /> <div>Project: Meet Marimo <br /> <br /> In this experiment, we get to know Marimo. Through '''microscopic observation''', you can see that Marimos '''perform photosynthesis'''—they release tiny oxygen bubbles. Look closely—maybe you can spot them! <br /> <br /> At the '''smallest magnification''' under the microscope, you can observe individual structures of '''Aegagropila linnaei''': '''Algal filament cells''': Small, chain-like structures that form the dense network of the Marimo. '''Chloroplasts''': Tiny green organelles that capture light for photosynthesis—this is where oxygen is produced '''Oxygen bubbles''': Small, clear spheres attached to the algae filaments—visible proof of active photosynthesis. '''Bacteria or microorganisms''': Sometimes, you may see tiny life forms that live in '''symbiosis''' with the Marimo.<br /> <br /> Watch carefully—how do the bubbles change when you shine light on the Marimo?<br /> <br /> Short Discription: [[File:Marimo.jpg|thumb|659x659px]]Marimo balls are round green algae found in cool lakes in Japan, Iceland, Estonia, and Scotland, especially in Lake Akan, Japan. Their name comes from the Japanese words mari (ball) and mo (algae). They grow slowly, only 5 mm per year, and can reach 30 cm in size. <br /> <br /> Their soft, velvety texture and ability to roll with water currents help them thrive in low light and cold temperatures.      Marimos are symbols of luck and harmony in Japan, celebrated at the Marimo Festival. Beyond culture, they are natural water purifiers, absorbing pollutants and releasing oxygen. Scientists study them as biosensors to monitor water quality and as potential living machines for movement-based technology.                                                                                                                        <br /> <br /> Ecosystem Role &amp; Movement, Marimos help their environment by: <br /> <br /> Producing oxygen through photosynthesis, benefiting fish and aquatic plants.                              <br /> <br /> Filtering water, removing pollutants, and maintaining balance. Providing shelter for tiny organisms. They float when oxygen bubbles form and sink when photosynthesis stops or water is stirred.  Pollution and tourism threaten Marimo populations. Conservation efforts in Lake Akan work to protect their habitats and ensure their survival.<br /> [[File:48a0369748be0a6ee374a79390663e07.jpg|thumb]]<br /> [[File:Th.jpg|thumb|303x303px]]<br /> [[File:LX8TZIjA.jpg|thumb|579x579px]]<br /> [[File:Pap-ihoA.jpg|thumb]]<br /> [[File:WhatsApp Video 2025-02-25 at 14.47.58.mp4|thumb]]<br /> Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors.<br /> <br /> [[File:Marimo microscope.jpg|thumb|687x687px]]<br /> [[File:6FFCCWTw.jpg|thumb]][[File:Photo 2025-02-25 23-51-45.jpg|thumb]]<br /> <br /> <br /> <br /> <br /> <br /> <br /> === Biography of Marimo Balls: The Fascinating World of Living Algae Spheres ===<br /> Birthplace and Origin:<br /> <br /> Marimo balls, also known as Cladophora balls, originate from clear, cool lakes in regions such as Japan, Iceland, Estonia, and Scotland. They are particularly famous in Japan, where they are found in Lake Akan on the island of Hokkaido. The name &quot;Marimo&quot; combines the Japanese words mari (ball) and mo (algae).<br /> <br /> Lifestyle and Characteristics:<br /> <br /> Marimo balls are composed of filaments of the green algae Aegagropila linnaei. The species Aegagropila linnaei belongs to the green algae family, which evolved over 1 billion years ago. Green algae were among the earliest photosynthetic organisms on Earth, contributing to the planet's oxygenation and forming the basis for plant evolution.             Their spherical structure is formed through a combination of gentle water currents and their ability to self-shape. They grow slowly, often only 5 millimeters per year, and can reach impressive sizes of up to 30 centimeters. Marimos have a vibrant green color and a soft, velvety surface.<br /> <br /> These algae are true survivors, capable of thriving in various water conditions thanks to their adaptation to low temperatures and limited light. They are also light-sensitive and roll in response to sunlight to ensure even exposure, a fascinating example of plant-like movement.<br /> <br /> Symbolism and Cultural Significance:<br /> <br /> In Japan, Marimo balls are considered good luck charms and symbols of purity, harmony, and connection to nature. An annual Marimo Festival is held at Lake Akan to celebrate these algae as a national treasure. They are also popular as low-maintenance pets in aquariums. The belief that Marimos can &quot;preserve love and wishes&quot; makes them a meaningful gift.<br /> <br /> Scientific Importance:<br /> <br /> Beyond their cultural role, Marimo balls have drawn attention in scientific research. Their unique structure and sensitivity to environmental conditions make them natural indicators of water quality. Researchers are exploring their potential as biosensors to monitor changes in pH levels, oxygen content, or pollutants. They also show promise as living machines, potentially being integrated into technologies for oscillators or actuators.<br /> <br /> Challenges and Conservation:<br /> <br /> Despite their resilience, Marimo balls are threatened by human activities such as pollution and tourism. The habitats of many natural populations have diminished. Conservation programs, such as those at Lake Akan, aim to preserve their environment and promote the natural reproduction of these algae.<br /> <br /> <br /> <br /> &lt;u&gt;Relationship with Water Ecosystems&lt;/u&gt;<br /> <br /> Marimo balls thrive in freshwater lakes, where their survival depends on the dynamic balance of light, temperature, nutrients, and water movement. In return, they contribute to the ecosystem by:<br /> <br /> - Providing Oxygen: Through photosynthesis, Marimos release oxygen into the water, supporting aquatic life. This benefits other organisms like fish and smaller aquatic plants.<br /> <br /> - Filtering the Environment: They absorb nutrients and pollutants from the water, helping maintain a cleaner, more balanced ecosystem.<br /> <br /> <br /> <br /> &lt;u&gt;Interaction with Watercurrents&lt;/u&gt;<br /> <br /> Water currents play a crucial role in shaping Marimo balls into their distinctive spherical form. This interaction benefits the algae by:<br /> <br /> - Ensuring even light exposure for photosynthesis.<br /> <br /> - Preventing sediment accumulation on their surface, which would block light and hinder growth. In turn, the algae ball adapts to the currents, rolling and growing symmetrically, demonstrating a cooperative relationship with its physical environment.<br /> <br /> <br /> <br /> &lt;u&gt;Microhabitat Provider&lt;/u&gt;<br /> <br /> The dense structure of Marimo balls can serve as a mini-ecosystem for microorganisms and small aquatic creatures:<br /> <br /> - Tiny organisms like plankton and microorganisms can shelter within the Marimo ball's filament network.<br /> <br /> - This mutualistic relationship allows the algae to recycle nutrients from the waste or activities of these inhabitants.<br /> <br /> Marimo balls perform photosynthesis when exposed to light, producing oxygen that accumulates in tiny bubbles on their surface.<br /> <br /> - Rising: When enough oxygen bubbles form, the Marimo ball becomes lighter and rises because the bubbles increase buoyancy.<br /> <br /> - Sinking: In darkness (e.g., at night), photosynthesis stops, the oxygen diffuses into the water, and the Marimo ball becomes heavier, causing it to sink.<br /> <br /> - Movement supports sinking: If the water is stirred (e.g., by waves or pumps), it can help release trapped oxygen bubbles, causing the Marimo to sink again.<br /> <br /> [[File:Photo 2025-02-25 23-50-27.jpg|thumb|543x543px]]<br /> <br /> &lt;u&gt;Marimo Balls: A Natural and Ecological Alternative to Synthetic Sensors&lt;/u&gt;<br /> <br /> Researchers have leveraged these properties to explore the potential of Marimo balls as small, living sensors. They investigated three possible applications:<br /> <br /> - Oscillators: Marimo balls could create regular, rhythmic movements similar to a pendulum by influencing their growth or movement patterns.<br /> <br /> - Biosensors: They could monitor environmental changes, such as water quality, based on their behavior and growth.<br /> <br /> - Actuators: Marimo balls could perform actions in response to signals, such as changing position or activating small devices.<br /> <br /> <br /> <br /> <br /> <br /> In comparison, synthetic chemical sensors are based on artificial materials and technologies that detect specific chemicals or changes in the chemical environment. They consist of a sensing material that reacts with the target chemical, a transducer that converts this reaction into an electronic signal, and a processing unit that displays the results. There are various types of such sensors, including gas sensors, which detect gases like oxygen or methane; ion sensors, which measure specific ions in liquids; and optical sensors, which detect changes in light caused by chemical reactions. A subset of these sensors are biosensors, which combine synthetic components with biological elements.<br /> <br /> Synthetic chemical sensors offer high sensitivity, fast and accurate measurements, and are often compact and easy to integrate.

Scientists study them as biosensors to monitor water quality and as potential living machines for movement-based technology.                                                                                                                        <br /> <br /> Ecosystem Role &amp; Movement, Marimos help their environment by:            Producing oxygen through photosynthesis, benefiting fish and aquatic plants.                              <br /> <br /> Filtering water, removing pollutants, and maintaining balance. Providing shelter for tiny organisms. They float when oxygen bubbles form and sink when photosynthesis stops or water is stirred.  Pollution and tourism threaten Marimo populations. Conservation efforts in Lake Akan work to protect their habitats and ensure their survival.<br /> [[File:48a0369748be0a6ee374a79390663e07.jpg|thumb]]<br /> [[File:Th.jpg|thumb]]<br /> [[File:LX8TZIjA.jpg|thumb]]<br /> [[File:B3Bq9N5w.jpg|thumb]]<br /> [[File:Pap-ihoA.jpg|thumb]]<br /> [[File:Marimo.jpg|none|thumb]]<br /> [[File:WhatsApp Video 2025-02-25 at 14.47.58.mp4|thumb]]<br /> Researchers explore Marimos as eco-friendly sensors that detect environmental changes and perform mechanical actions, making them a sustainable alternative to synthetic sensors.[[File:Fomes Fomentarius Hyphen documentation.pdf|thumb|Fomes Fomentarius Hyphen documentation.pdf |0x0px]]<br /> [[File:Marimo microscope.jpg|thumb]]<br /> [[File:Th (9).jpg|thumb]]<br /> [[File:6FFCCWTw.jpg|thumb]]</div>

How can we turn these processes into an immersive experience, to what extent can our concepts and technologies do justice to the plant world?<br /> <br /> In the agricultural industry, the combination of plant breeding and cybernetics is aimed at optimizing crops. Machine learning and robotics are used to achieve higher yields, disease resistance and climate adaptation.<br /> <br /> In the seminar ‘The Plant Plant’, we invite you to put aside any productivity factors and hand over control to the plants. With the help of DIY sensors and microcontrollers, we attempt to measure interactions between plants and their environment and transform the collected real-time data into a dynamic spatial atmosphere. We draw inspiration from cybernetic control systems and provoke various types of feedback between plants, the environment and humans. In the process, we take a critical look at upcoming relationships and effects. Our aim is to collectively develop a speculative sensing space - a human-scale environment whose atmospheric parameters such as light, temperature and air circulation are regulated by our ‘green control center’.<br /> <br /> This is a hands-on seminar. It includes three workshops in which we grow plants under different conditions, learn the basics of DIY electronics / sensor technologies and program control systems with Arduino / ESP32 microcontrollers, motor-driven devices and light sources. Furthermore, we discuss corresponding examples of artistic research in the context of media art.<br /> <br /> Requirements for participation: Interest in exploring plant environments, enthusiasm for tinkering and experimenting with DIY electronics, commitment to group work and passion for creating speculative spaces of experience. No prior knowledge is necessary, participants need their own computer / laptop. <br /> <br /> Please send your registration by Sunday (20 October) via e-mail, subject ‘The Plant Plant’, with a short letter of motivation (3-4 sentences) to christian.doeller@uni-weimar.de.<br /> <br /> <br /> &lt;u&gt;Participants:&lt;/u&gt;<br /> *[[Hanna Bremerich, Fiene Freist]]<br /> *[[Krittaporn Mahaweerarat]]<br /> *[[Annika Müller und Lilli Endres]]<br /> *[[Dania González Sanabria]]<br /> *[[Dyah Setyaningsih]]<br /> *[[Meng-Yun Tsai]]<br /> *[[Arın Aydın]]<br /> *Juyoun Oh<br /> *[[Fritzi Buhtz]]<br /> <br /> <br /> Exhibition @ Winterwerkschau 2025<br /> <br /> &lt;gallery&gt;<br /> File:Hanna Bremerich - Fiene Freist - 2.jpg<br /> File:Hanna Bremerich - Fiene Freist.jpg<br /> File:Hanna Bremerich - Fiene Freist - 1.jpg<br /> File:Dyah Setyaningsih.jpg<br /> File:Dyah Setyaningsih - 1.jpg<br /> File:The plant plant - 2.jpg<br /> File:Fritzi Buhtz -1.jpg<br /> File:Fritzi Buhtz - 2.jpg<br /> File:Fritzi Buhtz.jpg<br /> File:The plant plant - 1.jpg<br /> File:Juyoun Oh.jpg<br /> File:Arın Aydın.jpg<br /> File:The plant plant.jpg<br /> File:Meng-Yun Tsai.jpg<br /> File:Meng-Yun Tsai - 1.jpg<br /> File:Annika Müller - Lilli Enders.jpg<br /> File:Dania González.jpg<br /> File:Dania González - 2.jpg<br /> File:Dania González - 3.jpg<br /> File:Dania González - 1.jpg<br /> File:Krittaporn Mahaweerarat.jpg<br /> File:Krittaporn Mahaweerarat - 2.jpg<br /> File:Krittaporn Mahaweerarat - 1.jpg<br /> &lt;/gallery&gt;<br /> <br /> <br /> <br /> &lt;u&gt;Schedule:&lt;/u&gt;<br /> <br /> '''October 24, 13:30, M5 Room 204''' <br /> <br /> * first meeting<br /> <br /> '''October 31 - free'''<br /> <br /> '''November 1 - November 2, 10:00 - 16:00''' <br /> <br /> * Two-day workshop @ DIY Electronics Lab (B15, basement) / DIY Biolab (M5, Room 201)<br /> <br /> '''November 7, 13:30 - 17:00, DIY Electronics Lab''' <br /> <br /> * discuss workshop results<br /> *form working groups<br /> *first brainstorm in groups<br /> *networking &amp; data exchange<br /> '''November 14, 13:30 - 17:00, DIY Electronics Lab''' <br /> *presentation of artworks / context<br /> *presentation of ideas, feedback<br /> '''November 21, 13:30 - 17:00, DIY Electronics Lab'''<br /> *Progress of ideas / concepts<br /> *starting hands-on sessions: independent work and 1:1 consultations<br /> '''November 28, 13:30 - 17:00, DIY Electronics Lab'''<br /> *hands-on session: independent work and 1:1 consultations<br /> *please note: no class next week<br /> *&gt; time for progress and preparations for midterm presentation<br /> '''December 5, independent work (no official class)'''<br /> <br /> '''December 12, 13:30 - 17:00, DIY Electronics Lab'''<br /> *Midterm Presentations<br /> *hands-on session: independent work and 1:1 consultations<br /> '''December 19, 13:30 - 17:00, DIY Electronics Lab'''<br /> *hands-on session: independent work and 1:1 consultations<br /> *preparations Christmas break: to do / to get until first class in January 9?<br /> <br /> '''Christmas break'''<br /> <br /> '''January 9, 13:30 - 17:00, DIY Electronics Lab'''<br /> *check-in session: progress?<br /> *Winterwerkschau Application<br /> *hands-on session: independent work and 1:1 consultations<br /> '''January 16, 13:30 - 17:00, DIY Electronics Lab'''<br /> *hands-on session: independent work and 1:1 consultations<br /> *Brainstorm Winterwerkschau<br /> '''January 23, 13:30 - 17:00, DIY Electronics Lab'''<br /> *hands-on session: independent work and 1:1 consultations<br /> *Winterwerkschau – concept for space<br /> '''January 30, 13:30 - 17:00, DIY Electronics Lab'''<br /> *hands-on session: independent work and 1:1 consultations<br /> *get ready for Winterwerkschau<br /> '''February 2 – final: Winterwerkschau'''<br /> <br /> <br /> <br /> &lt;u&gt;Topics:&lt;/u&gt; <br /> *Growth of plants under different conditions<br /> *Hermetospheres / bottle gardens<br /> *DIY Electronics: Basic Sensors<br /> *DIY Electronics: Basic Actuators<br /> *DIY Electronics: Microcontrollers (Arduino / ESP) and cybernetic control systems<br /> *The basics of cybernetics, recursion, feedback<br /> *Immersive &quot;sensing spaces&quot;<br /> <br /> <br /> <br /> &lt;u&gt;Technology:&lt;/u&gt;<br /> *[https://github.com/diyElectronicsLab/ThePlantPlant The Plant Plant - GitHub Repo]<br /> <br /> <br /> &lt;u&gt;Artists:&lt;/u&gt;<br /> *Philippe Parreno<br /> *Ursula Damm<br /> *Marco Barotti<br /> *Cornelia Sollfrank<br /> *Katja Tillbörger<br /> *Robertina Šebjanič<br /> *Agnes Meyer-Brandis<br /> *Hicham Berrada<br /> *Ingo Vetter, Annette Weisser<br /> *Mel Chin<br /> *Maria Thereza Alves<br /> *...<br /> <br /> <br /> &lt;u&gt;Literature:&lt;/u&gt; <br /> *Donella Meadows''':''' ''Thinking in Systems.
