Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and ...
Are slimes smart?
This followed previous research from Dussutour and her colleagues, who discovered that blobs of slime mold could learn and remember substances that they didn't like, and communicate that information to other blobs of slime mold once they fused.
Do slime moulds have a brain?
Without a brain or nervous system they exhibit the executive wherewithal of an 8-month-old human baby — they're just amazing. Research published in Proceedings of the National Academy of Sciences in February 2021 investigates how one giant-bodied single-celled slime mold makes decisions.
Does slime mold have memory?
Simple one-celled organisms 'recall' the location of food using internal tubes made of a gel-like material. Even slime moulds have 'brains': a series of tubes that expand and contract to provide a memory of where food is located.
Does mold have a brain?
Slime Mold Doesn't Have a Brain, But It Can 'Remember' Where to Find Food. It may be a single-celled organism, but the slime mould Physarum polycephalum has some pretty fascinating tricks up its pretty yellow sleeves.

They are slime molds —yellow, oozing, amoeba-like organisms found on decaying logs and other moist areas. They have no brains. They have no neurons. Each consists of just a single, giant cell.
Is slime mold alien?
Slime molds are a remarkable lineage of amoebas that live in soil. While they spend part of their life as ordinary single-celled creatures, they sometimes grow into truly alien forms. Some species gather by the thousands to form multicellular bodies that can crawl.
How do slime mold communicate?
The form of communication used during the phase of aggregation in the cellular slime moulds represents a particularly amenable system for study. When these organisms run short of nutrients, some of the cells of the amoebal population emit rhythmic pulses of cyclic adenosine monophosphate.
Does mold have a nervous system?
How a single cell slime mold makes smart decisions without a central nervous system. Summary: Researchers have identified how the slime mold Physarum polycephalum saves memories -- although it has no nervous system. Having a memory of past events enables us to take smarter decisions about the future.
Do slime molds have nervous systems?
Like all slime molds, Physarum polycephalum has no brain or nervous system—yet it somehow “remembers” food sites for future reference.
How do slime molds solve mazes?
In the first part of the experiment, pieces of slime mould Physarum polycephalum were placed throughout the 3x3cm maze. To grow, the slime mould throws out tube-like structures called pseudopodia, and it soon filled the entire maze. The maze had four routes through, to get from one exit to the other.

What is the ability of slime molds to solve complex problems?
The striking abilities of the slime mold to solve complex problems, such as finding the shortest path through a maze, earned it the attribute "intelligent." It intrigued the research community and kindled questions about decision making on the most basic levels of life.
Is slime mold an animal?
Dec. 21, 2016 — It isn't an animal, a plant, or a fungus. The slime mold (Physarum polycephalum) is a strange, creeping, bloblike organism made up of one giant cell. Though it has no brain, it can learn from ... FROM AROUND THE WEB.
What are slime molds?
They are slime molds: gelatinous amoebae that have little to do with the kinds of fungal mold that ruin sourdough and pumpernickel. Biologists currently classify slime molds as protists, a taxonomic group reserved for "everything we don't really understand," says Chris Reid of the University of Sydney.
How do slime molds survive?
Slime molds survive best on a diet comprising two thirds protein and one third carbohydrates. Audrey Dussutour of the University of Paul Sabatier in France placed slime molds in the center of a clock face of 11 different pieces of food, each with a unique ratio of proteins and carbohydrates.
How did slime molds help the world?
When researchers placed oat flakes or other bits of food in the same positions as big cities and urban areas, slime molds first engulfed the entirety of the edible maps. Within a matter of days, however, the protists thinned themselves away, leaving behind interconnected branches of slime that linked the pieces of food in almost exactly the same way that man-made roads and rail lines connect major hubs in Tokyo, Europe and Canada.
How many slime molds did Reid use?
Ultimately, 23 of 24 slime molds reached the goal. But when Reid coated the rest of the petri dish in extracellular slime before introducing the slime molds, only eight of 24 found the food. All that preexisting slime confused the slime molds, preventing them from marking different areas as explored or unexplored. Reid thinks that a polycephalum in a labyrinth is similarly dependent on its slime, using it to first map the entire maze and then to remember which corridors are dead-ends.
How does slime mold navigate its environment?
As polycephalum moves through a maze or crawls along the forest floor , it leaves behind a trail of translucent slime. Reid and his teammates noticed that a foraging slime mold avoids sticky areas where it has already traveled. This extracellular slime, Reid reasoned, is a kind of externalized spatial memory that reminds polycephalum to explore somewhere new.
Why did Reid and his colleagues place slime molds in a petri dish behind a U-shaped barrier
To test this idea, Reid and his colleagues placed slime molds in a petri dish behind a U-shaped barrier that blocked a direct route to a piece of food. Because the barrier was made of dry acetate, the slime molds could not stick to it and climb over it; instead, they had to follow the contours of the U toward the food.
Where did Toshiyuki Nakagaki grow slime?
In the early 2000s Toshiyuki Nakagaki, then at Hokkaido University in Japan, and his colleagues chopped up a single polycephalum and scattered the pieces throughout a plastic maze. The smidgens of slime mold began to grow and find one another, burgeoning to fill the entire labyrinth.
What is the role of slime mold?
Like other slime molds found in nature, it fills an important ecological role, aiding in the decay of organic matter to recycle it into the food web.
Can a protist solve the traveling salesman problem?
Yet another team of researchers found that the protist could efficiently solve the traveling salesman problem , an exponentially complex mathematical task that programmers routinely use to test algorithms.
Is slime mold a problem?
In terms of overall biology, slime mold is extremely simple. And by that very fact, it's changing how we understand problem-solving. Just like other organisms, it needs food, it needs to navigate its environment, and it needs a safe place to grow and reproduce.
Can slime mold remember food?
This followed previous research from Dussutour and her colleagues, who discovered that blobs of slime mold could learn and remember substances that they didn't like, and communicate that information to other blobs of slime mold once they fused.
What is slime mold?
February 24, 2021. Slime molds, which are not actually fungi but cousins of single-celled amoebas, are goopy organisms that can find their way through a maze and remember the location of food —all without the benefit of a brain or nervous system.
Does slime mold expand?
Given their observations, the researchers think that when the slime mold detects food it releases some chemical that softens the walls of nearby tubes, allowing them to expand . However, Alim tells Live Science that their results give no clues as to what chemical this might be, adding that this will be the subject of future studies.
What is slime mold?
Slime molds are famous for their ability to form efficient networks between food sources that some say mimic road networks between cities.
