Biology is breaking out of the lab and clinic—and into our daily lives. Our new ability to engineer biology is transforming not just science, research, and healthcare, but how we produce our food, the materials we use, how we manufacture, and much, much more. From the latest scientific advances to the biggest trends, this show explores all the ways biology is today where the computing revolution was 50 years ago: on the precipice of revolutionizing our world in ways we are only just beginning to appreciate. Through conversations with scientists, builders, entrepreneurs, and leaders, host Lauren Richardson (along with the team at Andreessen Horowitz), examines how bio is going to fundamentally transform our future.

In short, bio is eating the world.

Anthony Atala, MD (the G. Link Professor and Director of the Wake Forest Institute for Regenerative Medicine, and the W. Boyce Professor and Chair of Urology), joins host Lauren Richardson (@lr_bio) to discuss the results and implications of the article "A tissue-engineered uterus supports live births in rabbits" by Renata S. Magalhaes, J. Koudy Williams, Kyung W. Yoo, James J. Yoo & Anthony Atala, published in Nature Biotechnology.In the introduction, we also discuss the new article "Ex utero mouse embryogenesis from pre-gastrulation to late organogenesis" by Alejandro Aguilera-Castrejon, Bernardo Oldak, Tom Shani, Nadir Ghanem, Chen Itzkovich, Sharon Slomovich, Shadi Tarazi, Jonathan Bayerl, Valeriya Chugaeva, Muneef Ayyash, Shahd Ashouokhi, Daoud Sheban, Nir Livnat, Lior Lasman, Sergey Viukov, Mirie Zerbib, Yoseph Addadi, Yoach Rais, Saifeng Cheng, Yonatan Stelzer, Hadas Keren-Shaul, Raanan Shlomo, Rada Massarwa, Noa Novershtern, Itay Maza & Jacob H. Hanna, published in Nature.
In this conversation, Stanford Professor Euan Ashley—geneticist, cardiologist, author of the new book, The Genome Odyssey, and first co-chair of the Undiagnosed Diseases Network—talks with Bio Eats World host Hanne Winarsky about one of the first places that genomic sequencing began to dramatically impact patients’ lives, and those of their families around them: in rare disease. Rare disease is by definition, well, rare. But collectively, it’s surprisingly common: 1 in 15. In this episode, we talk about how rare disease became the clear first use case for genome or exome-scale sequencing, and how sequencing—and other new technologies, and the new information they give us—is changing how rare disease gets diagnosed. Ashley tells the stories of how the Undiagnosed Disease Network solved some of the most perplexing medical mysteries with cutting edge tools and technologies; and the lessons learned from the world of rare disease that we can use to impact our knowledge and our treatment of those with common disease.
Leslie Vosshall, Ph.D, Professor at Rockefeller University and Howard Hughes Medical Institute (@leslievosshall) joins host Lauren Richardson (@lr_bio) to discuss the results and implications of two recent articles from her lab. First, "Sensory Discrimination of Blood and Floral Nectar by Aedes aegypti Mosquitoes" by Veronica Jove, Zhongyan Gong, Felix J.H. Hol, Zhilei Zhao, Trevor R. Sorrells, Thomas S. Carroll, Manu Prakash, Carolyn S. McBride, and Leslie B. Vosshall, published in Neuron. Second, "Fruitless mutant male mosquitoes gain attraction to human odor" by Nipun S Basrur, Maria Elena De Obaldia, Takeshi Morita, Margaret Herre, Ricarda K von Heynitz, Yael N Tsitohay, and Leslie B Vosshall, published in eLife.
In this episode, we talk with Jeff Hawkins—an entrepreneur and scientist, known for inventing some of the earliest handheld computers, the Palm and the Treo, who then turned his career to neuroscience and founded the Redwood Center for Theoretical Neuroscience in 2002 and Numenta in 2005—about a new theory about how the cells in our brain work to create intelligence. What exactly is happening in the neocortex as our brains process and interpret information and sensory input—like sight, smell, touch, or language, or math—to create a perception of and to navigate through the world around us?  a16z General Partner Vijay Pande and I talk to Jeff about the basic principles in this new idea of the brain’s learning methodology for creating not just human intelligence, but animal intelligence, artificial intelligence, even alien intelligence, which he lays out in his newly just released book, A Thousand Brains: A New Theory of Intelligence. The conversation covers how the neocortex builds models of the world around us, and what this could mean for how we design the next generation of truly intelligent machines. This episode goes all the way from tiny neurons and how they speak to each other to what’s happening in optical illusions to the future of humanity and beyond.
Aaron Phillips, CEP, MSc, PhD (Medicine), Assistant Professor at the University of Calgary, joins host Lauren Richardson to discuss the results and implications of the article "Neuroprosthetic baroreflex controls haemodynamics after spinal cord injury" by Jordan W.

Sea Turtle Medicine

Sea Turtle Medicine


Sea turtles occupy a very special biological niche in our world. And we still know relatively little about these creatures, one of the very few marine reptiles on the face of the planet. But as population growth and activity on coasts has exploded, so have our encounters with sea turtles... including, unfortunately, those that cause injury and disease. So what advances in technology and healthcare are helping us treat these incredible, 150 million year old animals—and what are we learning about them as a result? Max Polyak, Director of Rehabilitation at Loggerhead Marine Life Center in Juno Beach, Florida, shares with Bio Eats World host Hanne Winarsky the new advances in science and technology that are helping us treat sea turtles when they get sick or injured—and the new understanding about their biology, their behavior, and how they interact with the world around them those advances are leading to. The conversation covers everything from treating boat injuries with sea turtle-specific prosthetics; to using cutting edge human therapeutics on these animals in new ways; to the unique immune systems of these 2,000 pound leatherbacks (immune systems that have dealt with dinosaurs! meteor strikes! ice ages! and more); to how the microbiome of the sea turtle may answer one of the most intriguing mysteries about how these turtles behave; to ultimately, what sea turtle health can teach us about how we are all linked—and about the health of the entire ocean.
a16z general Vineeta Agarwala, MD Ph.D, and deal partners Judy Savitskaya, Ph.D and Justin Larkin, MD join host Lauren Richardson, Ph.D to discuss the results and implications of the article "Reconstitution of the oocyte transcriptional network with transcription factors" by Nobuhiko Hamazaki, Hirohisa Kyogoku, Hiromitsu Araki, Fumihito Miura, Chisako Horikawa, Norio Hamada, So Shimamoto, Orie Hikabe, Kinichi Nakashima, Tomoya S. Kitajima, Takashi Ito, Harry G. Leitch and Katsuhiko Hayashi, published in Nature.
In this episode of Bio Eats World, we talk to Dr. Jennifer Doudna—winner of the 2020 Nobel Prize for the co-discovery (with Emmanuelle Charpentier) of CRISPR-Cas9—about the art and science of biology. Huge breakthroughs such as Doudna's—which began with the identification of CRISPR in bacteria and was then built into a highly adaptable genome editing platform—are now fueling the evolution of the field. Fundamental knowledge that has largely come from curiosity-driven science has converged with enabling technologies, allowing scientists and biologists in particular to do things that even a couple of years ago, we would have found unimaginable. And biology has begun to shift from an artisanal process, to an industrial one—shifting from qualitative, descriptive science, to quantitative, predictive, high-throughput, science with increasing automation.  In this conversation, a16z General Partner Vijay Pande and Doudna talk about what happens as CRISPR and other tools to engineer and interrogate biology mature. What does the future of biology look like? Can discovery itself be engineered and industrialized—and how do we recognize the moment that becomes possible? Doudna talks about the arc of her career and work through this lens, from basic research to applied; what can be built tomorrow on today’s discoveries; and what at the end of the day may never be engineerable.
Tom  Ellis (@ProfTomEllis), Professor of Synthetic Genome Engineering at Imperial College London, joins host Lauren Richardson (@lr_bio) and a16z bio deal team partner Judy Savitskaya (@heyjudka) to discuss the results and implications of the article "Living materials with programmable functionalities grown from engineered microbial co-cultures" by  Charlie Gilbert, Tzu-Chieh Tang, Wolfgang Ott, Brandon A. Dorr, William M. Shaw, George L. Sun, Timothy K. Lu & Tom Ellis, published in Nature Materials. 
The way we pay for healthcare in the US has long been by fee-for-service: per doctor visit, per test, per surgery, per hospital stay. But that system has led to rapidly escalating volumes of services and cost to the system—without actually improving outcomes. What if we shifted everything towards paying for value—and outcomes—instead? In this episode, Todd Park, co-founder and executive chairman of Devoted Health, and formerly Chief Technology Officer and technology advisor for President Barack Obama; a16z General Partner Vijay Pande; and Bio Eats World host Hanne Winarsky—talk all about the megatrend of value-based care, and how it is redefining healthcare itself. Why is now the moment for this massive shift? How do we implement it? What does it mean for doctors and patients, insurers and policymakers? What is tech’s role in making it possible, and what's the business model and incentive for creating value?
In this episode, we share an episode of the brand new a16z Live podcast feed called “It’s Time to Heal”—a live conversation on audio/drop in chat app Clubhouse every Monday at 5pm PT, covering the latest trends and future of bio and healthcare with special guests and entrepreneurs, hosted by a16z bio partners Vineeta Agarwala, Jorge Conde, Vijay Pande, and Julie Yoo. Last week, a16z Bio General Partners and a16z cofounder Marc Andreessen talked with guest Nihkil Krishnan, comedian and author known for his Out-of-Pocket Substack newsletter and Slack community for healthcare builders, award winning children’s book, If You Give a Mouse Metformin, and past endeavors at TrialSpark and as healthcare analyst CB Insights. The conversation is all about the things that make you go “hmmm” in healthcare—the stuff we're all thinking but don't talk about, the places where exciting and surprising things are happening, and the places where you have to wonder why it works that way.
Seemay Chou (@seemaychou), Assistant Professor at the University of California, San Francisco, joins host Lauren Richardson (@lr_bio) to discuss the results and implications of the article “Ticks Resist Skin Commensals with Immune Factor of Bacterial Origin”, by Beth M. Hayes, Atanas D. Radkov, Fauna Yarza, Sebastian Flores, Jungyun Kim, Ziyi Zhao, Katrina W. Lexa, Liron Marnin, Jacob Biboy, Victoria Bowcut, Waldemar Vollmer, Joao H.F. Pedra, and Seemay Chou, published in Cell.
There's been a lot of talk (including on this show!) about the many kinds of innovations and technologies changing healthcare delivery for clinicians and patients. But what's happening behind the scenes in healthcare: in billing, in administration, and infrastructure? In this episode, we’re talking about the mountains of work (and paperwork) in the healthcare system, from reimbursement claims to patient registration to call centers scheduling appointments and much more—the enormous cost of inefficiency and waste in these areas adds to the healthcare system, and what kind of tech can help to improve it. Former Senator Bill Frist—a surgeon, Senate Majority Leader from 2003 to 2007, co-founder of Aspire Health, host of healthcare podcast A Second Opinion, and board member for many healthcare systems and companies; Malinka Walaliyadde, CEO and co-founder of Alpha Health, a tech company that automates healthcare revenue cycle management; and a16z General Partner Julie Yoo join Bio Eats World host Hanne Winarsky to discuss how innovation happens in healthcare's administrative "back office". The conversation covers what that waste currently costs us on a national and personal level; how (and what) new technologies like artificial intelligence and machine learning can automate to help cut cost out of the system; and how ultimately, we can allow innovate in these areas to allow the humans to do the really important work.
Andrew Read, Ph.D is the director of Huck Institutes of the Life Sciences, the Evan Pugh Professor of Biology and Entomology, and the Eberly Professor of Biotechnology at Pennsylvania State University. He joins host Lauren Richardson to discuss the results and implications of the article "An adjunctive therapy administered with an antibiotic prevents enrichment of antibiotic-resistant clones of a colonizing opportunistic pathogen"  by Valerie J Morley, Clare L Kinnear , Derek G Sim, Samantha N Olson , Lindsey M Jackson, Elsa Hansen, Grace A Usher, Scott A Showalter, Manjunath P Pai, Robert J Woods, and Andrew F Read, published in eLife.
What the heck is "junk DNA"? In this episode, a16z General Partner Jorge Conde and Bio Eats World host Hanne Winarsky talk to Professor Rick Young, Professor of Biology and head of the Young Lab at MIT—all about "junk" DNA, or non-coding DNA. Which, it turns out—spoiler alert—isn’t junk at all. Much of this so-called junk DNA actually encodes RNA—which we now know has all sorts of incredibly important roles in the cell, many of which were previously thought of as only the domain of proteins. This conversation is all about what we know about what that non-coding genome actually does: how RNA works to regulate all kinds of different gene expression, cell types, and functions; how this has dramatically changed our understanding of how disease arises; and most importantly, what this means we can now do—programming cells, tuning functions up or down, or on or off. What we once thought of as "junk" is now giving us a powerful new tool in intervening in and treating disease—bringing in a whole new category of therapies.
On this episode, a16z general partner Jorge Conde (@JorgeCondeBio) and bio deal team partner Andy Tran (@andy23tran) join host Lauren Richardson (@lr_bio) to discuss the results and implications of the article "Senolytic CAR T cells reverse senescence-associated pathologies" by Corina Amor, Judith Feucht, Josef Leibold, Yu-Jui Ho, Changyu Zhu, Direna Alonso-Curbelo, Jorge Mansilla-Soto, Jacob A. Boyer, Xiang Li, Theodoros Giavridis, Amanda Kulick, Shauna Houlihan, Ellinor Peerschke, Scott L. Friedman, Vladimir Ponomarev, Alessandra Piersigilli, Michel Sadelain & Scott W. Lowe, published in Nature.The introduction also references the article "Senolysis by glutaminolysis inhibition ameliorates various age-associated disorders" by Yoshikazu Johmura, Takehiro Yamanaka, Satotaka Omori, Teh-Wei Wang, Yuki Sugiura, Masaki Matsumoto, Narumi Suzuki, Soichiro Kumamoto, Kiyoshi Yamaguchi, Seira Hatakeyama, Tomoyo Takami, Rui Yamaguchi, Eigo Shimizu, Kazutaka Ikeda, Nobuyuki Okahashi, Ryuta Mikawa, Makoto Suematsu, Makoto Arita, Masataka Sugimoto, Keiichi I. Nakayama, Yoichi Furukawa, Seiya Imoto, Makoto Nakanishi
What are the fundamental principles that govern the physical world around us, and how did we get to them? In this episode, Bio Eats World hosts Hanne Winarsky and Lauren Richardson talk to Nobel prize-winning physicist Frank Wilczek about the essential principles of modern physics that have built our understanding of the world. Wilczek (who won the Nobel in 2004 for the discovery of asymptotic freedom in the theory of the strong interaction) dives into not just the principles of physics themselves—around space, time, fields, energy, and the laws that govern them—but the key intellectual driver that brought us to them, which he calls "radical conservatism", or the idea of pushing every theory to its limit. In this wide-ranging, philosophical conversation, Wilczek tells the stories of how certain key theories moved from ideas to principles, from cosmology to complementarity; how the complexity of biology arises from the simplicity of physics; what lead to the discovery of dark matter and axions; whether time can be reversed; what the future of the universe might look like; but most of all, how we as humans attempt to understand the beautiful, complicated world around us.
David Olson, Ph.D, Assistant Professor at the University of California, Davis, joins host Lauren Richardson to discuss the results and implications of the article "A non-hallucinogenic psychedelic analogue with therapeutic potential" by Lindsay P. Cameron, Robert J. Tombari, Ju Lu, Alexander J. Pell, Zefan Q. Hurley, Yann Ehinger, Maxemiliano V. Vargas, Matthew N. McCarroll, Jack C. Taylor, Douglas Myers-Turnbull, Taohui Liu, Bianca Yaghoobi, Lauren J. Laskowski, Emilie I. Anderson, Guoliang Zhang, Jayashri Viswanathan, Brandon M. Brown, Michelle Tjia, Lee E. Dunlap2, Zachary T.

Super Nice

It is interesting that this guy thinks aliens we encounter will be a product of darwian evolution at a time when we are giving animals and plants traits that we desire. We made super smart mice so we could watch them in a maze. They escaped into the wild. I think when we meet the aliens we will have tricked out our own genomes.

theese doctor treat pain patients like lab rats. somehow doctors have a higher claim over ones life and well being than the patient himself. if you really listen to this guy you will see the arrogance of themselves. its not the doctors job to determine if one is lying or tell them they are not in pain in their opinion. if a person has a desired treatment and it improves their life who the f**k do thesr people think they are to deny them the pursuit of happiness. whos gonna hold a higher regard for your own well being... yourself? or someone else? common sense has left the building on almost every aspect of life. the opiod bullshit isnt the factual reporting from the paitents but the arrogant opinion of the "experts". people are not animals! having to get permission for medication id a form of slavery. we have this false belief that slavery is gone when in fact it has expanded. slavery... The condition in which one person is owned as property by another and is under the owner's control, especially in involuntary servitude . My heathcare is not under my control, people forced off opiods when they dont want it is not voluntary. a child has to get a parent permission to do things. People are so busy trying to manage the lives of people they dont even dont even know when they cant even manage their own. misery loves company if a person takes opiods to improve their life, who the hell is anyone to tell them otherwise. It no different than telling a disbetic he cant have insulin even though it will improve his life. So under the ruse, since a few people abuse opiods we should deny others who dont the right to work and enjoy their familys. People who need opiods and are denied them suffer the same ill effects of person who is an addict. Addicts generally lose their ability to work and lose their family. People in chronic pain who are denied opiods generally lose their job and family and for many their life. suicide is rampant among people in constsnt pain, espesilly the non cancer patient as the cancer patient has the hope of death, something to look forward to "at least this will be over soon". The person who is in chronic pain who are not dying asks the question "do i got to live the rest of my life like this?" this is a very dire sitiation where hoplessness engulfs their life! cars kill people, people abuse cars and drive recklessly but prosperity and convienience is more important than the people they kill, same for opiods they create more prosperity than not. weve had knowlage at our fingertips and still we just take what spews from some "specialist" mouth who is speaking in their own self interest as the word of god than actually seeking the truth. Being the smartest man on earth doent give them authourity to run the lives of others We are now a world population of children who never grow up. unlike the rest of the world ill be in charge of my own life!
