Making Sense of Science features interviews with leading medical and scientific experts about the latest developments in health innovation and the big ethical and social questions they raise. The podcast is hosted by science journalist Matt Fuchs

Today’s podcast guest is Rosalind Picard, a researcher, inventor named on over 100 patents, entrepreneur, author, professor and engineer. When it comes to the science related to endowing computer software with emotional intelligence, she wrote the book. It’s published by MIT Press and called Affective Computing.

Dr. Picard is founder and director of the MIT Media Lab’s Affective Computing Research Group. Her research and engineering contributions have been recognized internationally, for example she received  the 2022 International Lombardy Prize for Computer Science Research, considered by many to be the Nobel prize in computer science.

Through her research and companies, Dr. Picard has developed wearable sensors, algorithms and systems for sensing, recognizing and responding to information about human emotion. Her products are focused on using fitness trackers to advance clinical quality treatments for a range of conditions.

Meanwhile, in just the past few years, numerous fitness tracking companies have released products with their own stress sensors and systems. You may have heard about Fitbit’s Stress Management Score, or Whoop’s Stress Monitor – these features and apps measure things like your heart rhythm and a certain type of invisible sweat to identify stress. They’re designed to raise your awareness about forms of stress like anxieties and anger, and suggest strategies like meditation to relax in real time when stress occurs.

But how well do these off-the-shelf gadgets work? There’s no one more knowledgeable and experienced than Rosalind Picard to explain the science behind these stress features, what they do exactly, how they might be able to help us, and their current shortcomings.

Dr. Picard is a member of the National Academy of Engineering and a Fellow of the National Academy of Inventors, and a popular speaker who’s given over a hundred invited keynote talks and a TED talk with over 2 million views. She holds a Bachelors in Electrical Engineering from Georgia Tech, and Masters and Doctorate degrees in Electrical Engineering and Computer Science from MIT. She lives in Newton, Massachusetts with her husband, where they’ve raised three sons.

In our conversation, we discuss stress scores on fitness trackers to improve well-being. She carefully describes the difference between commercial products that might help people become more mindful of their health and products that are FDA approved and really capable of advancing the science. We also discuss several fascinating findings and concepts discovered in Dr. Picard’s lab including the multiple arousal theory, a phenomenon you’ll want to hear about. And we talk about the complexity of stress, one reason it’s so tough to measure. For example, many forms of stress are actually good for us. Can fitness trackers tell the difference between stress that’s healthy and unhealthy?

On today’s episode of Making Sense of Science, I’m honored to be joined by Dr. Paul Song, a physician, oncologist, progressive activist and biotech chief medical officer. Through his company, NKGen Biotech, Dr. Song is leveraging the power of patients’ own immune systems by supercharging the body’s natural killer cells to make new treatments for Alzheimer’s and cancer. 

Whereas other treatments for Alzheimer’s focus directly on reducing the build-up of proteins in the brain such as amyloid and tau in patients will mild cognitive impairment, NKGen is seeking to help patients that much of the rest of the medical community has written off as hopeless cases, those with late stage Alzheimer’s. And in small studies, NKGen has shown remarkable results, even improvement in the symptoms of people with these very progressed forms of Alzheimer’s, above and beyond slowing down the disease.

In the realm of cancer, Dr. Song is similarly setting his sights on another group of patients for whom treatment options are few and far between: people with solid tumors. Whereas some gradual progress has been made in treating blood cancers such as certain leukemias in past few decades, solid tumors have been even more of a challenge. But Dr. Song’s approach of using natural killer cells to treat solid tumors is promising. You may have heard of CAR-T, which uses genetic engineering to introduce cells into the body that have a particular function to help treat a disease. NKGen focuses on other means to enhance the 40 plus receptors of natural killer cells, making them more receptive and sensitive to picking out cancer cells. 

Dr. Song is the grandson of the late Sang Don Kim, who was the first popularly elected Mayor of Seoul, South Korea. Dr. Song serves as the co-chair for a Campaign for a Healthy California. In 2013, he was named and served as the very first visiting fellow on healthcare policy in the California Department of Insurance. In addition, Dr. Song serves on the executive board of Physicians for a National Health Program California, People for the American Way, Progressive Democrats of America, Healthcare NOW, The Eisner Pediatric and Women's Center, and the Asian Pacific American Institute for Congressional Studies. Dr. Song graduated with honors from the University of Chicago, received his M.D. from George Washington University and completed his residency in radiation oncology at the University of Chicago. He sees Medicaid and uninsured patients at Dignity California Hospital.

With Dr. Song’s leadership, NKGen’s work on natural killer cells represents cutting-edge science that’s resulting in key findings about two of humanity’s most intractable diseases – contributing important pieces of the puzzle for treating them.

A new competition by the XPRIZE Foundation is offering $101 million to researchers if they discover therapies that allow seniors to perform like when they were 10 to 20 years younger. 

For today’s episode, I talked with Dr. Peter Diamandis, XPRIZE’s founder and executive chairman. Under Peter’s leadership, XPRIZE has launched 27 previous competitions with over $300 million in prize purses. 

The lastest contest aims to enhance healthspan, or the period of life when older people can play with their grandkids without any restriction, disability or disease. The biggest prize for this competition, called XPRIZE Healthspan, is $81 million for improvements that restore cognition, muscle and immunity by two decades. Sponsors include Hevolution Foundation, a nonprofit, and Chip Wilson, the founder of Lululemon and the nonprofit SOLVE FSHD.

In our conversation, Peter explains why exponential technologies make the current era the most exciting time in human history. We discuss the best mental outlook for becoming truly innovative; how to overcome the negativity bias in ourselves and in mainstream media; how Peter has shifted his own mindset to become more positive; his personal recommendations for healthy lifestyle; the future of education; and the importance of democratizing tech and innovation, among many other topics.

In addition to Peter’s role with XPRIZE, he's the Executive Founder of Singularity University. In 2014, Fortune named him one of the “World’s 50 Greatest Leaders.” He has started over 25 companies in health-tech, space, venture capital and education. Peter is the author of multiple New York Times bestselling books, linked below, and holds degrees in molecular genetics and aerospace engineering from MIT, as well as an M.D. from Harvard University.

A promising development in science in recent years has been the advance of technologies that take something natural and use technology to optimize it. This episode features a fascinating example: using tech to optimize psychedelic mushrooms.

These mushrooms have been used for religious, spiritual and medicinal purposes for thousands of years but only in the past several decades have scientists brought psychedelics into the lab to enhance them and maximize their therapeutic value.

Today’s podcast guest, Doug Drysdale, is doing important work to lead this effort. Drysdale is the CEO of a company called Cybin that has figured out how to make psilocybin more potent, so it can be administered in smaller doses without side effects.

Cybin isn’t Drysdale’s first go around at this. He has over 30 years of experience in the healthcare sector. During this time he’s raised around $4 billion of both public and private capital, and has been named Ernst and Young Entrepreneur of the Year. Before Cybin, he was the founding CEO of a pharmaceutical company called Alvogen, leading it from inception to around $500 million in revenues, across 35 countries. Drysdale has also been the head of mergers and acquisitions at Actavis Group, leading 15 corporate acquisitions across three continents.

In this episode, Drysdale walks us through the promising research of his current company, Cybin, and the different therapies he’s developing for anxiety and depression based not just on psilocybin but another psychedelic compound found in plants called DMT. He explains how they seem to have such powerful effects on the brain, as well as the potential for psychedelics to eventually support other use cases, including helping us strive toward higher levels of well-being. He goes on to discuss his views on mindfulness and lifestyle factors - such as optimal nutrition - that could help bring out the best in psychedelics.

You’ve probably heard about intermittent fasting, where you don’t eat for about 16 hours each day and limit the window where you’re taking in food to the remaining 8 hours.

But there’s another type of fasting, called fasting-mimicking diet, with studies pointing to important benefits for health and longevity. For today’s episode, I chatted with Dr. Valter Longo, a biogerontologist at the University of Southern California about all kinds of fasting, and particularly the fasting-mimicking diet, and strategies for making these approaches especially beneficial while minimizing really bad hunger as much as possible.

If you’ve ever spent more than a few minutes looking into fasting, you’ve almost certainly come upon the name Valter Longo. Dr. Longo is the author of the bestselling book, The Longevity Diet, and he is the best known researcher of how to do a fasting-mimicking diet, as well as researching the benefits.

A quick primer is helpful background for listening to this episode: with intermittent fasting, your body might begin to switch up its fuel type. Your body’s usually running on carbs you get from food, which gets turned into glucose, but without food, your liver starts making something called ketones, which are these molecules that are more efficient than glucose and good for the body in various other ways.

But in addition to intermittent fasting, there’s an alternative that could offer more benefits to your health and boost your longevity. This is the fasting-mimicking diet, the one researched by Dr. Longo, where you go for several days eating only the types of food that, in a way, keep themselves secret from your body. So at the level of your cells, the body still thinks that it’s fasting. This is the best of both worlds – you’re not completely starving because you do get to have some food, and you’re getting some of the amazing benefits that come with letting a fast run longer than you’d have with intermittent fasting.

This episode really explores the science of fasting. Dr. Longo talks about his extensive research on why this might be one of the best things you can do for health. He’s the director of the Longevity Institute in USC’s Leonard Davis School of Gerontology, and the director of the Longevity and Cancer program at the IFOM Institute of Molecular Oncology in Milan. In addition, Dr. Longo is the founder and president of the Create Cures Foundation in L.A., which focuses on nutrition for the prevention and treatment of major chronic illnesses. He authored the bestelling book, The Longevity Diet. v2 In 2016, he received the Glenn Award for Research on Aging, which was based on the discovery of both genes and dietary interventions able to regulate aging and prevent diseases, among many other awards. Dr. Longo received his PhD in biochemistry from UCLA and completed his postdoc in the neurobiology of aging and Alzheimer’s at USC.

In recent years, researchers of Alzheimer’s have made progress in figuring out the complex factors that lead to the disease. Yet, the root cause, or causes, of Alzheimer’s are still pretty much a mystery.

In fact, many people get Alzheimer’s even though they lack the gene variant we know can play a role in the disease. This is a critical knowledge gap for research to address because the vast majority of Alzheimer’s patients don’t have this gene variant.

A new study provides key insights into what’s causing the disease. The research, published in Nature Communications, points to a breakdown over time in the brain’s system for clearing waste, an issue that seems to happen in some people as they get older.

I asked Michael Glickman, a biologist at Technion University in Israel, who helped lead this research, to tell me about his approach to studying how this breakdown occurs in the brain, and how he tested a treatment that has potential to fix the problem at its earliest stages.

Tom Oxley is building what he calls a “natural highway into the brain” that lets people use their minds to control their phones and their computers. The device, called the Stentrode, could improve the lives of hundreds of thousands of people living with spinal cord paralysis, ALS and other neuro degenerative diseases.

Leaps.org talked with Dr. Oxley for today’s podcast. A fascinating thing about the Stentrode is that it works very differently from other “brain computer interfaces” you may be familiar with, like Elon Musk’s Neuralink. Surgeons implant the some BCIs directly into a person’s brain, but the Stentrode is much less invasive. Dr. Oxley’s company Synchron opts for an ingenious “natural” approach, using stents in blood vessels to access the brain, with some major advantages for a handful of people who’ve already started using the Stentrode. 

The audio improves about 10 minutes in. There was a minor headset issue early on but everything is audible throughout. 

In our conversation, Dr. Oxley talks about what it means to have a “Bluetooth brain,” the critical role played by AI in the present and future of BCIs, how BCIs compare to voice command technology, regulatory frameworks for revolutionary technologies, specific people with paralysis who’ve been able to regain some of their independence thanks to the Stentrode, what it means to be a neurointerventionist, how to scale BCIs so that more people can use them, the risks of BCIs malfunctioning, organic implants, and how BCIs help us understand the brain, among other topics. 

Dr. Oxley received his PhD in neuro engineering from the University of Melbourne in Australia. He is the founding CEO of Synchron and an associate professor and head of the vascular bionics laboratory at the University of Melbourne. He’s also a clinical instructor in the Deepartment of Neurosurgery at Mount Sinai Hospital. He’s completed more than 1,600 endovascular neurosurgical procedures on patients, including those with aneurysms and strokes, and has authored over 100 peer reviewed articles. 

Dr. Oxley’s work opens up game-changing opportunities for many patients, and his views on the present and future of BCIs are must listening for anyone who cares about health and technology.

In today’s podcast episode, Leaps.org Deputy Editor Lina Zeldovich speaks about the health and ecological benefits of farming crickets for human consumption with Bicky Nguyen, who joins Lina from Vietnam. Bicky and her business partner Nam Dang operate an insect farm named CricketOne. Motivated by the idea of sustainable and healthy protein production, they started their unconventional endeavor a few years ago, despite numerous naysayers who didn’t believe that humans would ever consider munching on bugs.  

Yet, making creepy crawlers part of our diet offers many health and planetary advantages. Food production needs to match the rise in global population, estimated to reach 10 billion by 2050. One challenge is that some of our current practices are inefficient, polluting and wasteful. According to nonprofit EarthSave.org, it takes 2,500 gallons of water, 12 pounds of grain, 35 pounds of topsoil and the energy equivalent of one gallon of gasoline to produce one pound of feedlot beef, although exact statistics vary between sources. 

Meanwhile, insects are easy to grow, high on protein and low on fat. When roasted with salt, they make crunchy snacks. When chopped up, they transform into delicious pâtes, says Bicky, who invents her own cricket recipes and serves them at industry and public events. Maybe that’s why some research predicts that edible insects market may grow to almost $10 billion by 2030. Tune in for a delectable chat on this alternative and sustainable protein.

In today’s podcast episode, I talk with Nir Barzilai, a geroscientist, which means he studies the biology of aging. Barzilai directs the Institute for Aging Research at the Albert Einstein College of Medicine.

My first question for Dr. Barzilai was: why do we age? And do we have to age? His answers were encouraging. We can’t live forever, but there are a few things we can do to age later, as he argues in the book.

He explained that centenarians differ from the rest of us because they have unique gene mutations that help them stay healthy longer. For most of us, the words “gene mutations” spell trouble—we associate these words with cancer or neurodegenerative diseases, but apparently not all mutations are bad. 

Centenarians may have essentially won the genetic lottery, but that doesn’t mean the rest of us are predestined to have a specific lifespan and health span—the amount of time spend living productively and enjoyably. “Aging is a mother of all diseases,” Dr. Barzilai told me. And as a disease, it can be targeted by therapeutics. Dr. Barzilai’s team is already running clinical trials on such therapeutics—and the results are promising.

More about Dr. Barzilai: He is scientific director of AFAR, American Federation for Aging Research. He is also the author of Age Later.  As part of his work, Barzilai studies families of centenarians and their genetics to learn how the rest of us can learn and benefit from their super-aging. He also organizing a clinical trial that is testing a specific drug that may slow aging.

In today’s podcast episode, I talk with Renee Wegrzyn,  appointed by President Biden as the first director of a federal agency created last year called the Advanced Research Projects Agency for Health, or ARPA-H. It’s inspired by DARPA, the agency that develops innovations for the Defense department and has been credited with hatching world changing technologies such as ARPANET, which became the internet.

Time will tell if ARPA-H will lead to similar achievements in the realm of health. That’s what President Biden and Congress expect in return for funding ARPA-H at 2.5 billion dollars over three years. 

How will the agency figure out which projects to take on, especially with so many patient advocates for different diseases demanding moonshot funding for rapid progress. 

I talked with Dr. Wegrzyn about the opportunities and challenges, what lessons ARPA-H is borrowing from Operation Warp Speed, how she decided on the first ARPA-H project which was just announced recently, why a separate agency was needed instead of trying to reform HHS and the National Institutes of Health to be better at innovation, and how ARPA-H will make progress on disease prevention in addition to treatments for cancer, Alzheimer’s and diabetes, among many other health priorities.

Dr. Wegrzyn’s resume is filled with experience for her important role. She was a program manager at DARPA where she focused on applying gene editing and synthetic biology to the goal of improving biosecurity. For her work there, she was given the Superior Public Service Medal and, just in case that wasn’t enough ARPA experience, she also worked at another ARPA that leads advanced projects in intelligence, called I-ARPA. Before that, she was in charge of technical teams in the private sector working on gene therapies and disease diagnostics, among other areas. She has been a vice president of business development at Gingko Bioworks and headed innovation at Concentric by Gingko. Her training and education includes a PhD and undergraduate degree in applied biology from the Georgia Institute of Technology and she did her postdoc as an Alexander von Humboldt Fellow in Heidelberg, Germany.

As Dr. Wegrzyn told me, she’s “in the hot seat” - the pressure is on for ARPA-H especially after the need and potential for health innovation was spot lit by the pandemic and the unprecedented speed of vaccine development. We'll soon find out if ARPA-H can produce something in health that’s equivalent to DARPA’s creation of the internet.

This episode is about a health metric you may not have heard of before: heart rate variability, or HRV. This refers to the small changes in the length of time between each of your heart beats.

Scientists have known about and studied HRV for a long time. In recent years, though, new monitors have come to market that can measure HRV accurately whenever you want.

Five months ago, I got interested in HRV as a more scientific approach to finding the lifestyle changes that work best for me as an individual. It's at the convergence of some important trends in health right now, such as health tech, precision health and the holistic approach in systems biology, which recognizes how interactions among different parts of the body are key to health.

But HRV is just one of many numbers worth paying attention to. For this episode of Making Sense of Science, I spoke with psychologist Dr. Leah Lagos; Dr. Jessilyn Dunn, assistant professor in biomedical engineering at Duke; and Jason Moore, the CEO of Spren and an app called Elite HRV. We talked about what HRV is, research on its benefits, how to measure it, whether it can be used to make improvements in health, and what researchers still need to learn about HRV.

*Talk to your doctor before trying anything discussed in this episode related to HRV and lifestyle changes to raise it.

What causes aging? In a paper published last month, Dr. David Sinclair, Professor in the Department of Genetics at Harvard Medical School, reports that he and his co-authors have found the answer. Harnessing this knowledge, Dr. Sinclair was able to reverse this process, making mice younger, according to the study published in the journal Cell.

I talked with Dr. Sinclair about his new study for the latest episode of Making Sense of Science. He said that turning back the clock on mouse age through what’s called epigenetic reprogramming – and understanding why animals get older in the first place – are key steps toward finding therapies for healthier aging in humans. We also talked about questions that have been raised about the research by Dr. Charles Brenner, Department Chair at City of Hope National Medical Center, and Dr. James Timmons, Senior Fellow at Queens Mary University.

Each afternoon, kids walk through my neighborhood, on their way home from school, and almost all of them are walking alone, staring down at their phones. It's a troubling site. This daily parade of the zombie children just can’t bode well for the future.

That’s one reason I felt like Gaia Bernstein’s new book was talking directly to me. A law professor at Seton Hall, Gaia makes a strong argument that people are so addicted to tech at this point, we need some big, system level changes to social media platforms and other addictive technologies, instead of just blaming the individual and expecting them to fix these issues.

Gaia’s book is called Unwired: Gaining Control Over Addictive Technologies. It’s fascinating and I had a chance to talk with her about it for today’s podcast. At its heart, our conversation is really about how and whether we can maintain control over our thoughts and actions, even when some powerful forces are pushing in the other direction.

We discuss the idea that, in certain situations, maybe it's not reasonable to expect that we’ll be able to enjoy personal freedom and autonomy. We also talk about how to be a good parent when it sometimes seems like our kids prefer to be raised by their iPads; so-called educational video games that actually don’t have anything to do with education; the root causes of tech addictions for people of all ages; and what kinds of changes we should be supporting.

Gaia is Seton’s Hall’s Technology, Privacy and Policy Professor of Law, as well as Co-Director of the Institute for Privacy Protection, and Co-Director of the Gibbons Institute of Law Science and Technology. She’s the founding director of the Institute for Privacy Protection. She created and spearheaded the Institute’s nationally recognized Outreach Program, which educated parents and students about technology overuse and privacy.

Professor Bernstein's scholarship has been published in leading law reviews including the law reviews of Vanderbilt, Boston College, Boston University, and U.C. Davis. Her work has been selected to the Stanford-Yale Junior Faculty Forum and received extensive media coverage. Gaia joined Seton Hall's faculty in 2004. Before that, she was a fellow at the Engelberg Center of Innovation Law & Policy and at the Information Law Institute of the New York University School of Law. She holds a J.S.D. from the New York University School of Law, an LL.M. from Harvard Law School, and a J.D. from Boston University.

Gaia’s work on this topic is groundbreaking I hope you’ll listen to the conversation and then consider pre-ordering her new book. It comes out on March 28.

Last Thursday, scientists at Columbia University published a new study finding that cutting down on calories could lead to longer lives. In the phase 2 trial, 220 healthy people without obesity dropped their calories significantly, and a test of their biological age showed that their rate of aging slowed by 2 to 3 percent in over a couple of years. Small though that may seem, it amounts to a decline of about 10 percent in the risk of death as people get older, according to the researchers' estimate. That's basically the same as quitting smoking.

Previous research has shown that restricting calories results in longer lives for mice, worms and flies. This research is unique because it applies those findings to people. It was published in Nature Aging.

But what did the researchers actually show? Does the new paper point to anything people should be doing to have longer, healthier lives? Spoiler alert: Maybe, but first, you'd want to consult a medical expert about it.

I had the chance to chat with someone with inside knowledge of the research -- Dr. Evan Hadley, director of the National Institute of Aging's Division of Geriatrics and Clinical Gerontology, which funded the study. Dr. Hadley describes how the research participants went about reducing their calories, as well as the risks and benefits involved. He also explains the "aging clocks" used to measure the benefits.

What makes for a good life? Such a simple question, yet we don't have great answers. Most of us try to figure it out as we go along, and many end up feeling like they never got to the bottom of it.

Shouldn't something so important be approached with more scientific rigor? In 1938, Harvard researchers began a study to fill this gap. Since then, they’ve followed hundreds of people over the course of their lives, hoping to identify which factors are key to long-term satisfaction.

Eighty-five years later, the Harvard Study of Adult Development is still going. And today, its directors, the psychiatrists Bob Waldinger and Marc Shulz, have published a book that pulls together the study’s most important findings. It’s called The Good Life: Lessons from the World’s Longest Scientific Study of Happiness.

In this podcast episode, I talked with Dr. Waldinger about life lessons that we can mine from the Harvard study and his new book.

Dr. Waldinger is Clinical Professor of Psychiatry at Harvard Medical School, in addition to being Director of the Harvard Study of Adult Development. He got his M.D. from Harvard Medical School and has published numerous scientific papers he’s a practicing psychiatrist and psychoanalyst, he teaches Harvard medical students, and since that is clearly not enough to keep him busy, he’s also a Zen priest.

His book is a must-read if you’re looking for scientific evidence on how to design your life for more satisfaction so someday in the future you can look back on it without regret, and this episode was an amazing conversation in which Dr. Waldinger breaks down many of the cliches about the good life… making his advice real and tangible. We also get into what he calls “side-by-side” relationships, personality traits for the good life, and the downsides of being too strict about work-life balance.

Meet Charles Brenner, the Longevity Skeptic. Brenner, a leading biochemist at City of Hope National Medical Center in L.A., has been attending the largest longevity conferences with one main purpose: to point out that some of the other speakers are full of it.

Brenner is "throwing cold water" on several scientists in the field of aging, accusing them of hyping various fountains of youth, despite limited evidence for these therapies.

In this podcast episode, Brenner sat down with Leaps.org to discuss his groundbreaking work on metabolism and his efforts to counter what he considers to be bad science.

In addition to bringing his candor to conferences, Brenner is applying it in academic journals, publishing a paper in September, "A Science-Based Review of the World's Best-Selling Book on Aging," in which he pans the author of this bestseller, David Sinclair, a Harvard biologist, for talking up the potential for humans to live far past 100. These aspirations may sound nice, but they're not backed by science, Brenner says. He's had high-profile debates online with Sinclair and Aubrey de Grey, a prominent biomedical gerontologist.

Meanwhile, in his own lab work, Brenner is credited with identifying a vitamin precursor called NR that seems to enable repair of cellular damage that happens as we get older - a major discovery that he's helped turn into a supplement, commercialized with a company called ChromaDex.

Whether it's possible to extend human lifespan is a pressing question as investments in longevity startups are projected to increase from $40 billion to $600 billion over the next three years. 

Brenner is an intriguing figure in these debates. Although he’s been introduced in public appearances as a longevity skeptic, he calls himself an optimist.

On today’s podcast episode, I had a chance to speak with Shai Efrati, a physician and professor in the schools of medicine and neuroscience at Tel Aviv University. Efrati also directs the Sagol Center for Hyperbaric Medicine and Research, and our conversation in this episode focuses on the potential health benefits of hyperbaric oxygen therapy.

Efrati's studies point to a connection between the use of hyperbaric chambers and improvements for a range of health problems such as Long Covid, strokes and traumatic brain injuries. Plus, Efrati has an early line of research suggesting that hyperbaric oxygen therapy could help protect against cognitive decline in healthy people and perhaps even slow down the overall aging process.

We talk about what’s going in on the body during hyperbaric oxygen therapy that could possibly lead to transformative benefits for patients, some of whom had searched for treatments previously and come up empty. We also discuss exactly where Efrati is with this line of inquiry, both what his studies have shown and the great deal of additional research that’s needed before the healthcare system can and should fully embrace hyperbaric oxygen therapy.

Efrati and I talk about why you can’t just go on Amazon and buy something that says hyperbaric – the only way it can have a positive effect is if you access the real version of the chamber and use it correctly under the supervision of a knowledgeable physician.

I also ask Efrati what we know about the short- and long-term risks for those who follow the research-based protocol on a regular basis. And what about accessibility to people without a lot of extra cash to spend on their health? Efrati is already rolling out this therapy at a small number of specialized clinics in places like the Villages retirement community in Florida.

My guest today for the Making Sense of Science podcast is Camila dos Santos, associate professor at Cold Spring Harbor Lab, who is a leading researcher of the inner lives of human mammary glands, more commonly known as breasts. These organs are unlike any other because throughout life they undergo numerous changes, first in puberty, then during pregnancies and lactation periods, and finally at the end of the cycle, when babies are weaned. A complex interplay of hormones governs these processes, in some cases increasing the risk of breast cancer and sometimes lowering it. Witnessing the molecular mechanics behind these processes in humans is not possible, so instead Dos Santos studies organoids—the clumps of breast cells donated by patients who undergo breast reduction surgeries or biopsies.

​Show notes:

2:52 In response to hormones that arise during puberty, the breast cells grow and become more specialized, preparing the tissue for making milk.

7:53 How do breast cells know when to produce milk? It’s all governed by chemical messaging in the body. When the baby is born, the brain will release the hormone called oxytocin, which will make the breast cells contract and release the milk.

12:40 Breast resident immune cells are including T-cells and B-cells, but because they live inside the breast tissue their functions differ from the immune cells in other parts of the body,

17:00 With organoids—dimensional clumps of cells that are cultured in a dish—it is possible to visualize and study how these cells produce milk.

21:50 Women who are pregnant later in life are more likely to require medical intervention to breastfeed. Scientists are trying to understand the fundamental reasons why it happens.

26:10 Breast cancer has many risks factors. Generic mutations play a big role. All of us have the BRCA genes, but it is the alternation in the DNA sequence of the BRCA gene that can increase the predisposition to breast cancer. Aging and menopause are the risk factors for breast cancer, and so are pregnancies.

29:22 Women that are pregnant before the age of 20 to 25, have a decreased risk of breast cancer. And the hypothesis here is that during pregnancy breast cells more specialized, as specialized cells, they have a limited lifespan. It's more likely that they die before they turn into cancer.

33:08 Organoids are giving scientists an opportunity to practice personalized medicine. Scientists can test drugs on organoids taken from a patient to identify the most efficient treatment protocol.

If you’re like me, you may have a case of email apnea, where you stop taking restful breaths when you open a work email. Or maybe you’re in the habit of shining blue light into your eyes long after sunset through your phone. Many of us are doing all kinds of things throughout the day that put us in a constant state of fight or flight arousal, with long-term impacts on health, productivity and happiness.

My guest for today’s episode is Sara Mednick, author of The Power of the Downstate, a book about the art and science of rest and relaxation – why it’s so important, the best ways to go about getting more of it, and the time of day when our bodies are biologically suited to get the most benefits from it. As a cognitive neuroscientist at the University of California, Irvine, Mednick has a great scientific background on this topic. Read her bio here.

Over the last few decades, perhaps no one has impacted healthy lifestyles more than Deepak Chopra. While some of his recommendations are criticized, Chopra has helped bring meditation, yoga and other practices for well-being into the mainstream, in ways that benefit the health of vast numbers of people every day.

His work has led many people, including some scientists and doctors, to accept new ways of thinking about alternative medicine, the power of mind over body, and the malleability of the aging process. 

It's been said that Chopra’s impact is such that our culture no longer recognizes him as a human being but as a pervasive symbol of new-agey personal health and spiritual growth. Last week, I had a chance to confirm that Chopra is, in fact, a human being – and deserving of his icon status – when I talked with him for the podcast. Showing no signs of slowing down at age 76, he described his prolific work, including two popular books in the past year and a range of technologies he’s developing, including his meditation app, meditation pods for the workplace, and a chatbot for mental health called Piwi.

Take a listen and get inspired to do some meditation and deep thinking on the future of health. As Chopra told me, “If you don’t have time to meditate once per day, you probably need to meditate twice per day.”

Highlights:

2:10: Chopra talks about meditation broadly and meditation pods, including the ones made by OpenSeed for meditation in the workplace.
6:10: The drawbacks of quick fixes like drugs for mental health.
10:30: The benefits of group meditation versus individual meditation.
14:35: What is a "metahuman" and how to become one.
19:40: The difference between the conditioned mind and the mind that's infinitely creative.
22:48: How Chopra's views of free will differ from the views of many neuroscientists.
28:04: Thinking Fast and Slow, and the role of intuition.
31:20: Athletic and creative geniuses.
32:43: The nature of fundamental truth.
34:00: Meditation for kids.
37:12: Never alone.Love and how AI chatbots can support mental health.
42:30: Extending lifespan, gene editing and lifestyle.
46:05: Chopra's mentor in living a long good life (and my mentor).
47:45: The power of yoga.
