How can victims of cystic fibrosis and other degenerative lung diseases be treated and even reverse? Stem cells may hold the key to a new world of treatments. Press play to learn:
Barry Stripp, Ph.D. and professor of medicine and director of the lung stem cell program at Cedars-Sinai Board of Governors Regenerative Medicine Institute, and John Mahoney, Ph.D., and head of the stem cell biology team at the Cystic Fibrosis Foundation Therapeutics Lab, join the podcast to share their work with lung regeneration and cystic fibrosis treatment.
Cystic fibrosis, while not inherently destroying the lung, it disrupts bodily systems that allow the lung to function correctly. Due to mucus buildup after not allowing lungs to be appropriately hydrated, asphyxiation is one of the most common causes of death among CF sufferers.
Since the repercussions and long-term maintenance requirements for lung transplants, they are not a viable solution for long periods. Due to this, the hope is to apply stem cell techniques and gene correction to aid in lung tissue regeneration.

Christopher Logan is an avid health and nutrition reader who is continuously searching for the next best thing in the wide world of physical culture and herbalism. He is the co-founder and CEO of Lost Empire Herbs, an online store that offers herbal medicine for men's health and herbal supplements for athletic performance. Logan has an interesting perspective on the history of snake oil in the United States and its impact on pharmaceuticals, supplements, and herbs.

Christopher Logan discusses the philosophy of scientism as it relates to health and sickness. The United States is one of the most technologically advanced countries on the planet. In contrast, it has one of the worst birth outcomes. The long-term effects of the use of pesticides on crops grown in the United States serves as a reminder that less technology is better in terms of a healthy population.
Less technology and living a more natural lifestyle appears to have a healthier impact on society. Supplements and herbs are not considered medicine in spite of the fact that they reduce or eliminate deficiencies in the human body. On the other hand, the FDA conducts intensive studies on proposed drugs and approves them even though they do not necessarily work as intended.

Luke Burgis is an entrepreneur by experience who worked on Wall Street for a short time before moving to California to jump into the startup world in Silicon Valley. He established four companies and experienced many successes and failures while in California. From the outside, Burgis appeared to have everything. However, he felt he was on a never-ending journey to find "something" while not really understanding what that something was.
Click on play to learn:
As a successful entrepreneur, Burgis struggled with wanting one thing one day and wanting something else the next day. Dealing with conflicting wants on an ongoing basis led to Burgis stepping back to revaluate his life. As an avid reader, he studied various theories of want and the self and found a connection with René Girard's ideas on the concept of mimetic desires and what drives them.
His research led him to spending three years in Italy in the quest to identify the driving forces of his life. As a student of psychology, classical philosophy, and theology, he learned to create distance to examine his true desires and distinguish the origins of his aspirations. Burgis learned how to identify various systems of desire and realized that people move in and out of those systems as their life changes over time. He wrote a book, Wanting: The Power of Mimetic Desire in Everyday Life that explores why we want what we want.
This profound book shows readers how mimetic desire is present in their relationships. One of the chapters focuses on the rise of scapegoating and resulting violence that demonstrates how understanding the power of mimetic desire psychology can keep us from becoming involved in the negative behaviours of blaming others.

How can CRISPR technology be viewed in perspective past regular lab use? By examining the bacteria left after genetic editing, the potential for new research emerges. Press play to learn:
Chase Beisel, a Group Leader (W2) at Helmholtz Institute for RNA-based Infection Research in Würzburg (Germany), discusses his research using CRISPR bacteria beyond their typical scope of work.
While CRISPR is commonly used and known for manipulating DNA strings, there is actually a fascinating byproduct left behind. Using the bacteria responsible for the editing during the process, they are still viable for use after editing and can be seen as an extensive natural immune system.
By watching and studying how mRNA functions within the system, there may be possibilities for new technology. By recruiting mRNA and turning them into guide RNA, the nature of how this change occurs can be uncovered and applied to other areas of study.

Jianghong Min is a graduate student with the Department of Genetics at Harvard Medical School who is currently involved in genomics studies of the heritability of CRISPR-based gene drive cassettes to control specific functionalities in non-human species and their impact on genetic diseases. He is working on these projects at MIT with the Sculpting Evolution Group and Kevin Esvelt, Assistant Professor.
Listen to the podcast to discover:
Min is working on a study involving the genetic editing of heritable genes using gene drive cassettes in a non-human genus. The study is in the exploration phase at this time. Of particular interest is the evolution of a gene drive system once it is released into the wild. How much genetic information can be included in the gene drive cassettes? How much control of the heritability of the gene drives do scientists have once the are released into the wild?
Min is especially interested in discovering unintended consequences. Could these heritable changes spread into other nearby species? He believes in the precautionary principle that scientists should not intervene until all of the negative effects are known and should identify the greater impact of genetically modifying these organisms.

"Nature, over millions of years, developed the immune system in vertebrate animals," says Martin Steegmaier. And one of those developments is the antibody—a large protein that detects and neutralizes threats to the body, like viruses and bacteria.
Learn how one company is using this to tackle cancer, and discover:
Steegmaier is head of research at MorphoSys AG, a company that's focused on antibody discovery and development, with an aim to become a leader in hematology-oncology and autoimmune disease treatment.
He discusses the benefits and observed effects of antibody-based treatment for various cancers, and the key differences between the use of antibodies (large molecules) and small molecules in the treatment of cancer. He also explains the function of the most notable antibody treatments on the MorphoSys drug discovery platform, one of which was launched last July for the treatment of an aggressive type of cancer called diffuse large B-cell lymphoma.

Dr. Ana Soto is a Professor of Immunology at Tufts University who by training is a physician with a deep interest in science. She began working in labs while attending the university and eventually discovered an interest in how estrogens and hormones control the proliferation of cells in the breast, uterus, etc. Dr. Soto is currently conducting research on a new theory of cell proliferation and carcinogenesis at The Ana Soto – Carlos Sonenshein Lab at Tufts University.
Click on play to learn:
Dr. Soto and Schonnenschein have been focusing their research on the origins of carcinogenesis known as the Tissue Organization Field Theory (TOFT). While their studies involve the biomechanics of morphogenesis, SMT theorizes that mutations are central to the development of cancer. The TOFT theory suggests that the mutations are an epiphenomenon.
According to Dr. Soto, all cells will proliferate and produce tissue architecture that is normal. When cancer is introduced by some mechanism, there is an alteration in the organization of cells and a tumor may begin to grow. One of the goals of their research is to identify the mechanism that results in the alteration of the organization of cells and the subsequent development of cancer tissues. Several influences may be at play in this situation: biochemical factors and their receptors; biochemical communication; the proliferation of mechanical forces, bioelectricity, and the formation of an extracelluar matrix.

One of the most profound questions in life is how did cells first materialize on Earth? Joana C. Xavier, Ph.D. is a scientist at University College London, bioengineer, and author who has focused her life's work on finding possible answers to that question. She has an interest in systems biology, specifically the origin, evolution, and diversity of prokaryotic cells, minimal cells and chassis cells. Examples of Dr. Xavier's work in computational biology include the analyses of the evolution of genes, species, and communities. She is also involved in large scale and integrative studies of metabolism.
Press play to learn more about:
Dr. Xavier has a keen interest in the origin and evolution of life and believes that hydrothermal vents may have been the site where the first cells appeared. The ocean floor is well protected from the ultraviolet light produced by the sun. Natural chimneys form around the hydrothermal vents that release heated fluids necessary for cell development and they create a dynamic environment that would be favourable for life to evolve.
Because the focus of Dr. Xavier's research is on the possibility of the origins of life deep in the ocean, collecting samples to conduct research is extremely limited and expensive. As a computational biologist, she uses massive amounts of specific types of data collected by other scientists and researchers to conduct big data analysis to test her theories.
The Earth is believed to be 4.5 billion years old which adds to the complexity of finding the origin of the first cell. Dr. Xavier believes there must be some type of necessity at the origin of the first cells that is governed by laws we do not yet understand. While it is difficult to determine exactly when life first emerged on the planet, some believe that it took place shortly after the Earth was formed. Identifying which genes are the oldest is challenging and the search continues to establish the last universal common ancestor (LUCA) which may lead to answers to the question of how cells materialized on Earth.

How can the water you drink contribute to the formation or treatment of cancer? Deuterium present in the water may play a significant role. Press play to learn:
Functional medicine doctor Petra Davelaar joins the podcast to discuss her research on deuterated water and how it may be a critical factor in health and cancer.
Deuterium present in water and the food around us is often overlooked but plays a significant role in maintaining health and staving off potentially severe diseases. The lower the deuterium present in what is put into the body, the better it is.
Despite the evidence that deuterium plays such a significant role in many different processes within the body, the medical industry continues to overlook the benefits of manipulating the levels within the body. However, drinking deuterium-depleted water and honing one's diet may be effective strategies to combat certain diseases.
