A hidden link between amino acid metabolism and peripheral neuropathy in diabetes

Épisode 53

vendredi 16 juin 2023 • Durée 39:38

Peripheral neuropathy afflicts millions of diabetes patients around the world, causing sensations from tingling to pain to complete numbness. For our season finale, we discussed peripheral neuropathy with bioengineer Christian Metallo, whose recent research has uncovered how insulin-regulated metabolism of lipids and amino acids contributes to peripheral neuropathy. Dr. Metallo spoke with us about the inspiration for this research and explained his team’s key findings about the links between insulin, the amino acids serine and glycine, and peripheral neuropathy in diabetes patients.

The AI model that’s building novel proteins

Épisode 52

mercredi 24 mai 2023 • Durée 27:58

Proteins, with their unique structures, have evolved over billions of years to perform a host of different functions essential to the processes that keep us alive. Using the same principles as artificial intelligence chatbots, scientists at Salesforce developed an AI language model called ProGen. Using large protein databases, ProGen was trained on the biological syntax of amino acid sequences, allowing it to design functional 3D protein structures. These proteins have useful properties that may be leveraged in healthcare and biosciences. In this episode, we talk with Dr. Nikhil Naik, Director of AI Research at Salesforce, leading the team of scientists behind ProGen. We discuss the inspiration for ProGen, the implications of AI-generated proteins, and the future of protein engineering in light of ever-evolving biotechnologies. Music credits: “Summer Lofi” and “Summer Winds” by Rukudzo.

At-home healthcare: monitoring Parkinson’s disease with radio waves

Épisode 43

mercredi 16 novembre 2022 • Durée 38:51

The prevalence of Parkinson’s disease has grown more than 50% in recent years, and early onset diagnosis is increasing at an even faster rate. Due to its slow, subtle progression and variable response to medications, this condition can be difficult for clinicians to manage. The work of Dr. Dina Katabi, Director of the MIT Center for Wireless Networks and Mobile Computing, may change that. Her team has shown that discrete, radio wave emitting devices in the home can be used to track patient movement and health parameters like sleep quality. In this episode, Dr. Katabi explains how this work will make healthcare more precise and accessible than ever before. Music Credits: “Land of the midnight sun” and “I hope you hear this” by Rukudzo.

The chronic disease caused by a common virus

Épisode 42

mercredi 1 juin 2022 • Durée 36:04

Over 2.8 million people worldwide live with multiple sclerosis (MS), a disease in which the body’s immune system attacks the protective myelin coating around nerves in the brain and spinal cord. People with MS can experience pain, fatigue, memory problems, vision loss, and other debilitating symptoms. MS is relatively rare, but new research has found a causal link between Epstein-Barr Virus, one of the most common human viruses, and MS. In this episode, we talk to Dr. Alberto Ascherio, a Professor of Epidemiology at Harvard School of Public Health, about the 20-year longitudinal databank that reveals Epstein-Barr Virus as a causal factor in MS.

A telescope to look into life, before life

Épisode 41

mercredi 11 mai 2022 • Durée 35:16

Imagine having a telescope that could allow you to see whether a syndrome will manifest in the future. Imagine being able to use it to cure diseases before they can even occur. For Dr. Thomas McElrath, MD-PhD in the Division of Maternal-Fetal Medicine at the Brigham & Women’s Hospital, this telescope exists and is called LIFECODES. The LIFECODES Biobank is an extensive biobank of samples collected for over 14 years with data on over 6,000 pregnancies. It is used to look at biomarkers associated with pregnancy complications and the effects of environmental exposures on pregnancy outcomes. In this episode, we have interviewed Dr. McElrath to talk about his recent work published in Nature. He has leveraged these data to shed light on normal pregnancy progression to uncover new biomarkers that can be used to diagnose syndromes months before clinical presentation.

On the traces of our African past

Épisode 40

mercredi 20 avril 2022 • Durée 40:30

We do not often think about our past as a species. What are the changes that made us like we are now? When, where, and why did these changes happen? Can we go back in history and find the answers to these questions? Archaeologists reconstruct human behavior in the past, mainly using things that people left behind, or this is what they used to do. In recent years, the possibility to study ancient DNA has revolutionized our way of looking at the past. Ancient DNA allows us to explore human diversity in different places and times and understand what factors shaped it, revealing mysteries about our history. We have interviewed Mary E. Prendergast, Assistant Professor of Anthropology at Rice University and a leader of one of the largest-scale studies of ancient DNA in Africa. Listen to this episode to find out how Dr. Prendergast and her team could use ancient DNA from individuals who lived between 18,000-400 years ago to explore how people interacted as far back as the last 80,000-50,000 years. Music by Doug Maxwell, “A good day on the African Planes” and Joel Cummings, “Robots and Aliens”.

Alzheimer’s Disease from the Inside Out

Épisode 39

mercredi 30 mars 2022 • Durée 51:08

Alzheimer’s disease affects millions of people and their families. Scientists have made extraordinary progress characterizing the pathology of Alzheimer’s and working to find effective treatments. As scientists continue to unlock more and more about the disease and how to combat it, how can we address the challenges currently facing doctors, patients, and caregivers? In this 360 Perspective episode, we talk about the history of Alzheimer’s, the stigma surrounding it, disparities in healthcare, and the impacts on caregivers. We interviewed Drs. Carl Hill, Stephanie Kalb, Jason Karlawish, Gad Marshall, and Stephen Salloway to discuss these issues.

The buddy system behind puberty

Épisode 38

mercredi 9 mars 2022 • Durée 28:59

Puberty may seem like a chaotic phase of life, but the process is precisely controlled by a series of timed signals beginning in the brain. Before we are born, a set of neurons secreting GnRH (gonadotropin-releasing hormone) migrate to the brain and set up the hub that will control reproductive processes. During this time, these neurons recruit newborn astrocytes, and they stick together throughout life. In this episode, we speak with Dr. Vincent Prévot, Director of the Development and Plasticity of the Neuroendocrine Brain Team of INSERM, to discuss his research on the neuroendocrine regulators of reproduction. Dr Prévot tells us about how the GnRH neurons actively recruit astrocytes, and how this process can be interrupted. Listen to hear more about the processes that lead to puberty, environmental factors that affect the natural timing of puberty, and why it is important for puberty to happen at the “right time.” Additional music provided by Aaron Troutman.

A vaccine to stop the most invisible of all viruses

Épisode 37

mercredi 16 février 2022 • Durée 35:15

The disease that would ultimately become known AIDS was first diagnosed in June 1981. At that time, researchers had not yet determined what caused it, and by the time most patients presented with symptoms, they had only months to live. After four decades of effort by the global research community, the development of promising experimental HIV vaccines has now finally come true. We have interviewed Dr. Paolo Lusso, Chief of the Viral Pathogenesis Section at the National Institute of Allergy and Infectious Diseases, to discuss his research in developing and testing promising HIV vaccines. In this episode, Dr. Lusso explains why it took so long to develop a vaccine with the potential to defeat this “master of disguise and transformation”, words he uses to refer to HIV. Listen to this episode to learn more about the immune system, the process of developing a vaccine, and the challenges scientists had to face to stop the most invisible of all viruses. “I miss you (reimagined)”, music composition administered by Rukudzo © 2022 Rukudzo Kanyemba.

The Gambling Rules of Cell Behavior

Épisode 36

mercredi 26 janvier 2022 • Durée 40:48

“Every gambler knows that the secret to survivin' is knowin' what to throw away and knowin' what to keep...”. Have you ever listened to “The Gambler” by Kenny Rogers? He knew how to play the game right, and it turns out that so does our body! Dr. Phil Jones, a Professor of Cancer Development at the University of Cambridge UK, works on uncovering the dynamics of cell behavior. He found that human cells play a dice game, balancing the odds between production and shedding. This game protects the genomes of our cells, throwing out most of the damage we accumulate during our lives. However, mutations can change the game's rules and increase the odds in favor of dividing cells, potentially leading to cancer. Acquiring mutations is easier than we think: ultraviolet light in sunshine or tobacco-derived chemicals can cause extensive mutations in our body. Despite this, our tissue can surprisingly continue to look and function normally. Listen to this episode to learn how normal tissues restrain the expansion of mutant clones, so very few of them progress to form tumors. Phew!
