Stem Cell Assay Market Predicted to Accelerate the Growth by 2017-2025 Dagoretti News - Dagoretti News

Team builds the 1st living robots – EarthSky

Scientists from the University of Vermont (UVM) and Tufts University in Massachusetts said on January 13, 2020, that theyve now assembled living cells into entirely new life-forms. They call them living robots, or xenobots for the frog species from whose cells the little robots sprang. The scientists describe them as tiny blobs, submillimeter in size (a millimeter is about 1/25th of an inch, so these little blobs are smaller than that). The blobs contain between 500 and 1,000 cells. They can heal themselves after being cut. The blobs have been able to scoot across a petri dish, self-organize, and even transport minute payloads. Maybe, eventually, theyll be able to carry a medicine to a specific place inside a human body, scrape plaque from arteries, search out radioactive contamination, or gather plastic pollution in Earths oceans.

And, yes, the scientists do acknowledge possible ethical issues. More about that below.

Joshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research, said in a statement:

These are novel living machines. Theyre neither a traditional robot nor a known species of animal. Its a new class of artifact: a living, programmable organism

You look at the cells weve been building our xenobots with, and, genomically, theyre frogs. Its 100% frog DNA but these are not frogs. Then you ask, well, what else are these cells capable of building?

The results of the new research were published January 13 in the Proceedings of the National Academy of Sciences.

In their published paper, these scientists wrote:

Most technologies are made from steel, concrete, chemicals, and plastics, which degrade over time and can produce harmful ecological and health side effects. It would thus be useful to build technologies using self-renewing and biocompatible materials, of which the ideal candidates are living systems themselves. Thus, we here present a method that designs completely biological machines from the ground up: computers automatically design new machines in simulation, and the best designs are then built by combining together different biological tissues. This suggests others may use this approach to design a variety of living machines to safely deliver drugs inside the human body, help with environmental remediation, or further broaden our understanding of the diverse forms and functions life may adopt.

The new creatures were designed on a supercomputer at UVM, and then assembled and tested by biologists at Tufts University. The scientists statement described their process this way:

With months of processing time on the Deep Green supercomputer cluster at UVMs Vermont Advanced Computing Core, the team including lead author and doctoral student Sam Kriegman of UVM [@Kriegmerica on Twitter] used an evolutionary algorithm to create thousands of candidate designs for the new life-forms. Attempting to achieve a task assigned by the scientists like locomotion in one direction the computer would, over and over, reassemble a few hundred simulated cells into myriad forms and body shapes. As the programs ran driven by basic rules about the biophysics of what single frog skin and cardiac cells can do the more successful simulated organisms were kept and refined, while failed designs were tossed out. After a hundred independent runs of the algorithm, the most promising designs were selected for testing.

Then the team at Tufts, led by Michael Levin and with key work by microsurgeon Douglas Blackiston transferred the in-silico designs into life. First they gathered stem cells, harvested from embryos of African frogs, the species Xenopus laevis [African clawed frogs; hence the name xenobots.]

These were separated into single cells and left to incubate. Then, using tiny forceps and an even tinier electrode, the cells were cut and joined under a microscope into a close approximation of the designs specified by the computer.

Assembled into body forms never seen in nature, the cells began to work together. The skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion as guided by the computers design, and aided by spontaneous self-organizing patterns allowing the robots to move on their own.

These reconfigurable organisms were shown to be able move in a coherent fashion and explore their watery environment for days or weeks, powered by embryonic energy stores. Turned over, however, they failed, like beetles flipped on their backs.

Later tests showed that groups of xenobots would move around in circles, pushing pellets into a central location spontaneously and collectively. Others were built with a hole through the center to reduce drag. In simulated versions of these, the scientists were able to repurpose this hole as a pouch to successfully carry an object.

Wow yes?

The scientists said they see this work as part of a bigger picture. And they acknowledged that some may fear the implications of rapid technological change and complex biological manipulations. Levin commented:

That fear is not unreasonable. When we start to mess around with complex systems that we dont understand, were going to get unintended consequences.

However, he said:

If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules.

He said much of science is focused on:

controlling the low-level rules. We also need to understand the high-level rules.

I think its an absolute necessity for society going forward to get a better handle on systems where the outcome is very complex. A first step towards doing that is to explore: how do living systems decide what an overall behavior should be and how do we manipulate the pieces to get the behaviors we want?

In other words, he said:

this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences.

Bongard added:

Theres all of this innate creativity in life. We want to understand that more deeply and how we can direct and push it toward new forms.

Bottom line: Scientists said in early January 2020 that theyve created the first living robots, or xenobots, assembled from the cells of frogs. Their creators promise advances from drug delivery to toxic waste clean-up.

SCIENCE

Newswise A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need.

Now a team of scientists has repurposed living cells--scraped from frog embryos--and assembled them into entirely new life-forms. These millimeter-wide "xenobots" can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient)--and heal themselves after being cut.

"These are novel living machines," saysJoshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

The new creatures were designed on a supercomputer at UVM--and then assembled and tested by biologists at Tufts University. "We can imagine many useful applications of these living robots that other machines can't do," says co-leader Michael Levin who directs theCenter for Regenerative and Developmental Biologyat Tufts, "like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque."

The results of the new research were published January 13 in theProceedings of the National Academy of Sciences.

BESPOKE LIVING SYSTEMS

People have been manipulating organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years--copying the body forms of known animals.

But this research, for the first time ever, "designs completely biological machines from the ground up," the team writes in their new study.

With months of processing time on the Deep Green supercomputer cluster at UVM'sVermont Advanced Computing Core, the team--including lead author and doctoral student Sam Kriegman--used an evolutionary algorithm to create thousands of candidate designs for the new life-forms. Attempting to achieve a task assigned by the scientists--like locomotion in one direction--the computer would, over and over, reassemble a few hundred simulated cells into myriad forms and body shapes. As the programs ran--driven by basic rules about the biophysics of what single frog skin and cardiac cells can do--the more successful simulated organisms were kept and refined, while failed designs were tossed out. After a hundred independent runs of the algorithm, the most promising designs were selected for testing.

Then the team at Tufts, led by Levin and with key work by microsurgeon Douglas Blackiston--transferred the in silico designs into life. First they gathered stem cells, harvested from the embryos of African frogs, the speciesXenopus laevis. (Hence the name "xenobots.") These were separated into single cells and left to incubate. Then, using tiny forceps and an even tinier electrode, the cells were cut and joined under a microscope into a close approximation of the designs specified by the computer.

Assembled into body forms never seen in nature, the cells began to work together. The skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion as guided by the computer's design, and aided by spontaneous self-organizing patterns--allowing the robots to move on their own.

These reconfigurable organisms were shown to be able move in a coherent fashion--and explore their watery environment for days or weeks, powered by embryonic energy stores. Turned over, however, they failed, like beetles flipped on their backs.

Later tests showed that groups of xenobots would move around in circles, pushing pellets into a central location--spontaneously and collectively. Others were built with a hole through the center to reduce drag. In simulated versions of these, the scientists were able to repurpose this hole as a pouch to successfully carry an object. "It's a step toward using computer-designed organisms for intelligent drug delivery," says Bongard, a professor in UVM'sDepartment of Computer ScienceandComplex Systems Center.

LIVING TECHNOLOGIES

Many technologies are made of steel, concrete or plastic. That can make them strong or flexible. But they also can create ecological and human health problems, like the growing scourge of plastic pollution in the oceans and the toxicity of many synthetic materials and electronics. "The downside of living tissue is that it's weak and it degrades," say Bongard. "That's why we use steel. But organisms have 4.5 billion years of practice at regenerating themselves and going on for decades." And when they stop working--death--they usually fall apart harmlessly. "These xenobots are fully biodegradable," say Bongard, "when they're done with their job after seven days, they're just dead skin cells."

Your laptop is a powerful technology. But try cutting it in half. Doesn't work so well. In the new experiments, the scientists cut the xenobots and watched what happened. "We sliced the robot almost in half and it stitches itself back up and keeps going," says Bongard. "And this is something you can't do with typical machines."

CRACKING THE CODE

Both Levin and Bongard say the potential of what they've been learning about how cells communicate and connect extends deep into both computational science and our understanding of life. "The big question in biology is to understand the algorithms that determine form and function," says Levin. "The genome encodes proteins, but transformative applications await our discovery of how that hardware enables cells to cooperate toward making functional anatomies under very different conditions."

To make an organism develop and function, there is a lot of information sharing and cooperation--organic computation--going on in and between cells all the time, not just within neurons. These emergent and geometric properties are shaped by bioelectric, biochemical, and biomechanical processes, "that run on DNA-specified hardware," Levin says, "and these processes are reconfigurable, enabling novel living forms."

The scientists see the work presented in their newPNASstudy--"A scalable pipeline for designing reconfigurable organisms,"--as one step in applying insights about this bioelectric code to both biology and computer science. "What actually determines the anatomy towards which cells cooperate?" Levin asks. "You look at the cells we've been building our xenobots with, and, genomically, they're frogs. It's 100% frog DNA--but these are not frogs. Then you ask, well, what else are these cells capable of building?"

"As we've shown, these frog cells can be coaxed to make interesting living forms that are completely different from what their default anatomy would be," says Levin. He and the other scientists in the UVM and Tufts team--with support from DARPA's Lifelong Learning Machines program and the National Science Foundation-- believe that building the xenobots is a small step toward cracking what he calls the "morphogenetic code," providing a deeper view of the overall way organisms are organized--and how they compute and store information based on their histories and environment.

FUTURE SHOCKS

Many people worry about the implications of rapid technological change and complex biological manipulations. "That fear is not unreasonable," Levin says. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences." A lot of complex systems, like an ant colony, begin with a simple unit--an ant--from which it would be impossible to predict the shape of their colony or how they can build bridges over water with their interlinked bodies.

"If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules," says Levin. Much of science is focused on "controlling the low-level rules. We also need to understand the high-level rules," he says. "If you wanted an anthill with two chimneys instead of one, how do you modify the ants? We'd have no idea."

"I think it's an absolute necessity for society going forward to get a better handle on systems where the outcome is very complex," Levin says. "A first step towards doing that is to explore: how do living systems decide what an overall behavior should be and how do we manipulate the pieces to get the behaviors we want?"

In other words, "this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences," Levin says--whether in the rapid arrival of self-driving cars, changing gene drives to wipe out whole lineages of viruses, or the many other complex and autonomous systems that will increasingly shape the human experience.

"There's all of this innate creativity in life," says UVM's Josh Bongard. "We want to understand that more deeply--and how we can direct and push it toward new forms."

The ‘xenobot’ is the worlds newest robot and it’s made from living animal cells – The Loop

Forget gleaming metal droids -- the robots of the future may have more in common with the average amphibian than with R2D2.

A team of scientists have found a way to not just program a living organism, but to build brand new life-forms from scratch using cells, creating what researchers are calling xenobots.

Tiny in size, but vast in potential, these millimetre-sized bots could potentially be programmed to help in medical procedures, ocean cleanup and investigating dangerous compounds, among other things.

"They're neither a traditional robot nor a known species of animal, said researcher Joshua Bongard in a news release. It's a new class of artifact: a living, programmable organism."

In the introduction for the research published in Proceedings of the National Academy of Sciences (PNAS) on Monday, researchers point out that the traditional building blocks weve used for robots and tech -- steel, plastic, chemicals, etc. -- all degrade over time and can produce harmful ecological and health side-effects.

After realizing that the best self-renewing and biocompatible materials would be living systems themselves, researchers decided to create a method that designs completely biological machines from the ground up.

The bots are made out of stem cells taken from frog embryos -- specifically, an African clawed frog called xenopus laevis, which supplied the inspiration for the name xenobot. To design the xenobots, the possible configurations of different cells were first modeled on a supercomputer at the University of Vermont.

The designs then went to Tufts University, where the embryonic cells were collected and separated to develop into more specialized cells. Then, like sculptors (if sculptors used microsurgery forceps and electrodes), biologists manually shaped the cells into clumps that matched the computer designs.

Different structures were sketched out by the computer in accordance with the scientists goal for each xenobot.

For example, one xenobot was designed to be able to move purposely in a specific direction. To achieve this, researchers put cardiac cells on the bottom of the xenobot. These cells naturally contract and expand on their own, meaning that they could serve as the xenobots engine, or legs, and help move the rest of the organism, which was built out of more static skin cells.

In order to test if the living robots were truly moving the way they were designed to, and not just randomly, researchers performed a test that has stumped many a living creature.

They flipped the robot on its back. And just like a capsized turtle, it could no longer move.

When researchers created further designs for the bots, they found that they could design them to push microscopic objects, and even carry objects through a pouch.

"It's a step toward using computer-designed organisms for intelligent drug delivery," says Bongard.

The possible uses for these tiny robots are numerous, researchers say.

In biomedical settings, one could envision such biobots (made from the patients own cells) removing plaque from artery walls, identifying cancer, or settling down to differentiate or control events in locations of disease, the research paper suggests.

A robot made out of metal or steel generally has to be repaired by human hands if it sustains damage. One major benefit that researchers found of creating these robots out of living cells was how they reacted to physical damage.

A video taken by the researchers showed that when one of their organisms was cut almost in half by metal tweezers, the two sides of the wound simply stitched itself back together.

These living robots, researchers realized, could repair themselves automatically, something you cant do with typical machines, Bongard said.

Because they are living cells, they are also naturally biodegradable, Bongard pointed out. Once theyve fulfilled their purpose, theyre just dead skin cells, making them even more optimal for usage in medical or environmental research.

Although scientists have been increasingly manipulating genetics and biology, this is the first time that a programmable organism has been created from scratch, researchers say.

This new research takes scientists a step closer to answering just how different cells work together to execute all of the complex processes that occur every day in animals and humans.

"The big question in biology is to understand the algorithms that determine form and function," said co-leader Michael Levin in the press release. He directs the Center for Regenerative and Developmental Biology at Tufts.

"What actually determines the anatomy towards which cells co-operate? he asked. You look at the cells we've been building our xenobots with, and, genomically, they're frogs. It's 100 per cent frog DNA -- but these are not frogs. Then you ask, well, what else are these cells capable of building? As we've shown, these frog cells can be coaxed to make interesting living forms that are completely different from what their default anatomy would be.

Of course, a biological organism created and programmed by humans which is capable of healing itself might sound a little alarming. After all, one of the sponsors of the research is the Defense Advanced Research Projects Agency, which is affiliated with the U.S. military.

Researchers acknowledged in the press release that the implications around such technological and biological advancements can be worrying at times.

That fear is not unreasonable, Levin said. However, he believes that in order to move forward with science, we should not hold back from complex questions. This study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences.

"I think it's an absolute necessity for society going forward to get a better handle on systems where the outcome is very complex," Levin says. "A first step towards doing that is to explore: how do living systems decide what an overall behavior should be and how do we manipulate the pieces to get the behaviors we want?"
