Episode 152 centers on a lively conversation between Kevin and Dr. Kate Oland Galligan as they trace her path from a curious undergrad to a passionate fascia educator and clinician. The duo challenges old perceptions of fascia, recounting stories from early lab experiences where fascia was simply “ripped out,” and contrasting them with new insights on its dynamic, interconnected nature. They reveal how subtle fascial restrictions can cause significant clinical symptoms—linking pelvic imbalances to jaw pain—and explore the emerging field of mind-body connections in fascial therapy. 0:00:00 | Introduction 0:00:55 | Introducing Kate Introducing Fascia 0:17:06 | Fascia Mini Lesson * 0:20:00 | Rip That Fascia Out! 0:37:14 | Get Ready for Annual Debriefing 0:39:00 | The Hip Bone is Connected to the Jaw Bone 1:03:08 | We're on Substack! * 1:06:13 | Mind-Body Connections 1:21:45 | Staying Connected * Breaks ★ If you cannot see or activate the audio player, go to: theAPprofessor.org/podcast-episode-152.html

In Asia, bamboo has been used as a construction material for thousands of years. Prized for its availability, strength, and flexibility, it has over a thousand uses—including scaffolding during the construction of high rises in Hong Kong. So why has it been slow to be adopted by the global construction industry? It's a sustainability advocate's dream: it sequesters carbon; provides wildlife habitats; supplies biofuel. Some species mature in just five years and can auto-regenerate after harvesting. But how does it stack up against concrete, steel, and timber? With the right ingredients, engineered bamboo shows major promise as a regenerative building material of the future. Brock University's Dr. Amir Mofidi is an expert in bio-based composites and he's developing cold-hardy, construction-ready strains that can handle North American climates.Join the Building Good community today:https://www.buildinggood.caLinkedIn

In this podcast episode, MRS Bulletin's Sophia Chen interviews Michael Dickey of North Carolina State University about the discovery and mechanical properties of glassy gels. Dicky credits his postdoc Meixiang Wang who, while studying ionic liquids, created the first glassy gel. Dicky's group found that the mechanical properties of their glassy gel include shape memory, self-healing, and adhesion. While other materials may demonstrate comparable toughness and stretchiness, the glassy gel offers an advantage because of its simple curing process. This work was published in a recent issue of Nature.

Abstract: Extracellular matrix (ECM) deposition after central nervous system (CNS) injury leads to inhibitory scarring in mammals, whereas it facilitates axon regeneration in the zebrafish. However, the molecular basis of these different fates is not understood. Here, we identify small leucine-rich proteoglycans (SLRPs) as a causal factor in regeneration failure. We demonstrate that the SLRPs Chondroadherin, Fibromodulin, Lumican, and Prolargin are enriched in human, but not zebrafish, CNS lesions. Targeting SLRPs to the zebrafish injury ECM inhibits axon regeneration and functional recovery. Mechanistically, we find that SLRPs confer structural and mechanical properties to the lesion environment that are adverse to axon growth. Our study reveals SLRPs as previously unknown inhibitory ECM factors in the human CNS that impair axon regeneration by modifying tissue mechanics and structure.

Sophia Chen of MRS Bulletin interviews Zhenan Bao of Stanford University about her research team’s development of a biomimetic soft electronic skin (e-skin) composed of an array of capacitors capable of effectively measuring and discriminating shear force in real time. Read the abstract in Science Robotics. CHEN: Zhenan Bao is a professor at Stanford University whose research team developed this robot. She says the key design of the robot is a network of force sensors on its fingertip that tell the robot when to retract. BAO: Without sensor feedback, the robot would not know how much it can press on an object before it should stop. CHEN: They’ve also shown that the robot can respond to feedback to place a ping-pong ball into an arrangement of different round holes. She says that this type of tactile robot could be useful in all sorts of situations.BAO: Any robot that will need to have the ability to manipulate objects and being in contact with objects will need this type of sensing feedback.CHEN: Basically, it works because they’ve invented a stretchable electronic skin covered in sensors that can sense force from multiple directions. It can sense forces perpendicular to the skin, or normal force, as well as forces parallel to the skin, known as shear force. And both forces are necessary for grabbing, holding, and placing objects. Try it. Grab a coin or something between your fingers—you’ll notice how you need to apply pressure to hold it, but also sense shear force to keep it from sliding. Previously, electronic skins couldn’t sense shear force very effectively. The sensors were fragile and they also could only be placed sparsely on the robot. But Bao has figured out a way for the robot to sense the shear force, and she’s placed those sensors at high density on the skin. The more sensors crammed onto a surface, the better you can control the robot’s sense of touch. Bao says some of the tactile properties of the electronic skin are comparable to the sensitivity of human skin. For example, if the skin experiences a shear pressure increase of 1 pascal, the electronic signal output of the skin will triple in size. 1 Pascal is about the pressure of a dollar bill resting on a table. BAO: We are able to use fingertips to feel the most delicate texture and structures on the surface. CHEN: In fact, to create this electronic skin, she’s borrowed a design element from human skin itself, a structure called the spinosum, which lies between the epidermis and dermis. They’re these little hill-like structures for sensing the direction a force is coming from.BAO: If you add this hill-like structure, then depending on whether the force comes from left side or right side, because this dome or hill will be pressed from an angle, then only mechanoreceptor that’s on the opposite side of the direction of the force will be pressed and activated. This gives us a sense of direction of the shear force. CHEN: The hill structures are pretty small—a fraction of a millimeter in size—and she can pack them densely onto the electronic skin. But if you zoom in even further, you can see the other key structural design on their electronic skin. Bao’s group has fabricated tiny pyramids, tens of microns wide at the base. BAO: After a force is applied, these pyramids allow the elastic material to bounce back to its original shape once the force is removed.CHEN: And in the future, Bao wants to borrow even more design elements from human physiology. She wants the sensors to pre-process some of the signal, like neurons do. BAO: This neural-like signal processing lets humans gather a large amount of information and train our brain to learn the patterns of information with very little consumption of energy.

Imagine being able to transform an insulating material into an electrical conductor just by touching it with a magnet. Materials chemist Dr Andrew Goodwin is using the concepts of order and disorder to design new materials with amazing functionality that could transform our future in ways limited only by our imagination.

Andrew Cairns and Ines Collings, DPhil students in the Goodwin Group, explain how they make single crystals in the lab and study their unusual properties. By showing how to break the rules governing 'normal' materials, this research could lead to the design of brand new and useful substances in future.

This talk discusses the movement of cells at different depth levels within cartilage. In addition, a study designed to determine how cartilage responds to shear stress is outlined.

The main purpose of this study is to understand influences of bulk structure of materials on strength behavior as well as water storage and transfer in order to assess durability and weathering. Therefore, a selection of different methods are applied and compared to optimize the understanding of material structure and physico-mechanical behavior. Optical microscopy (Digital Image Analysis) and scanning electron microscopy as well as water vapor permeability, biaxial flexural strength and ultrasonic velocity are measured on different natural materials: sandstones with clayey, silicious or calcareous binder, oolithic and micritic magnesian limestones and a thermally aged Proconnesian marble. Microstructurales and macrostructurales properties of these materials are studied before and after artificial weathering (freeze-thaw cycles). First, and in order to validate the efficiency of the digital image analysis to characterize porosity and structure, traditional porosity measurements as water ad- and absorption and mercury porosimetry are crosschecked with the result obtained from digital image analysis. Limits of each methods are also defined. Then, validations of non-destructive and semi-destructive methods are also pursued to evaluate their potential value to replace and complement standardized methods. By analysis of linear correlations, some essential mechanisms should be underlined, which may connect the macrostructure to the microstructure of the material. A systematic method of analysis should clearly appear and emphasize the role of the structure (grain size, grain contact and pore shape) on physical and mechanical behavior. The main parameters leading to weathering should then be identified and models of correlations drawn. Correlations between the various physico-mechanical properties could ameliorate the possibilities to assess durability and weathering in the natural environment.
