Penna, whose groundbreaking study was published in Nature Physics, has made some radical discoveries about how cells move. Researchers, including Nuno Araújo at the University of Lisbon, have discovered universal patterns that would have profound implications on robotics, artificial intelligence, and video game development. The study, titled "Evidence of universal conformal invariance in living biological matter," was a collaborative effort involving the Department of Physics and the Center for Theoretical and Computational Physics at the Faculty of Sciences of the University of Lisbon, as well as academics from institutions in Denmark, Switzerland, and the United Kingdom.
Nuno Araújo is a professor and researcher at the Department of Physics at the University of Lisbon. He was an inspiration for this important study. Additionally, he shared that the research focused on developing cell models and found a shared rhythm behind their migratory behavior. This major advancement provides truly compelling opportunities for interdisciplinary and transformative work between physics and biology. This finding demonstrates that living biological matter has a universal scale invariance. This knowledge might improve how robots navigate and ultimately help improve the development of artificial intelligence systems.
A Universal Pattern in Cell Movement
The research demonstrated that cell models behave in similar, predictable patterns. This indicates that they exhibit similar movement dynamics regardless of the biological system, whether it be microbe, fish, or human. This finding goes against the conventional wisdom in biology, where we like to think of each system as being special.
"While in physics we systematically find the same patterns in different systems, in biology, there is always a tendency to think that each system is unique," said Nuno Araújo.
To illustrate this idea, Araújo relied on the visual analogy of broccoli to define the difference. Inside broccoli He lovingly explained to them how broccoli resembled a tree. As you can see, even without its branches, it still has that tree-like structure. This analogy illustrates the idea of scale invariance—a major feature of the study’s results.
"A broccoli has the shape of a tree, but if we cut off each branch, it also looks like a tree. If I showed you a picture of each piece and asked which one was the largest, you wouldn't be able to tell. That is scale invariance, and that's what we discovered here. All these systems share the same scale invariance," he clarified.
Implications for Robotics and Artificial Intelligence
The consequences of this finding reach well beyond pure physics or biology. By revealing these universal properties of how cells move Araújo hopes to push the field a leap forward. This expertise stands to transform technology industries nationwide, from robotics to artificial intelligence. Researchers might apply these principles to develop pruned algorithms that lead a robot to its destination more effectively. They can create better portrayals of reality within video games.
The study offers a guide for applying physics methodologies to examine biological systems, and the reverse. Such an interdisciplinary approach will only create new insights and innovations for the advancement of both fields.
"This opens doors for us to use physics techniques to study biological systems, but also for biological systems to be used to study physical phenomena," stated Araújo.
Collaborative Research Across Borders
The research team included specialists from four different universities around Europe, which emphasizes the significance of international collaboration in scientific progress. Bringing their distinct expertise to the study, physicists and biologists worked together closely. Together, they sought to understand intricate biological patterns and behaviors by using the fundamental truths of physics.
Nuno Araújo's involvement highlights the University of Lisbon's active role in pioneering research that bridges multiple scientific disciplines. The partners include institutions located in Denmark, Switzerland, and the United Kingdom. This golden Age of Innovation and Discovery is testimony to the global nature of scientific inquiry and Innovation.
This comparative study brings together concepts and theories of physics and biology. It’s an example of how truly interdisciplinary, fundamental research can yield groundbreaking insights that feed directly back into very diverse applied technologies.
