About this episode

Climate change and environmental degradation are increasingly threatening our ability to feed a burgeoning human population. Switching to agricultural practices that support beneficial soil microbes, and thus healthy soils, may help farmers achieve the yields required for continued food security. Dr Zachary Senwo from the College of Agriculture, Life and Natural Sciences at Alabama A&M University has spent over two decades exploring how agricultural management practices impact soil health. In an extensive new project, his team is investigating soil nitrogen cycling and the role of microbes in soil health.

Dr. Jon Reinders | A genetic breakthrough for farming: editing corn inside the plant, not the lab

Corn is a cornerstone of modern agricultural food production, particularly in North America. Humans have selectively bred such crops over generations to create better yields, improved appearance and flavor and enhanced disease resistance. However, what if we could skip these arduous rounds of selective breeding and improve a crop’s stability and reliability regardless? Deep within the genetic blueprint of every maize kernel, scientists are aiming to achieve just this. In a recent groundbreaking study, Dr. Jon Reinders of Corteva Agriscience and his colleagues have unveiled a powerful new way to create genetically improved corn, not in a lab dish, but inside the plant itself. This new method is faster, cleaner, safer, and could transform how we grow our most essential crops.

Professor Jeremy Maurer | Building a seismic timeline of the Nippes earthquake

Sitting directly over a complex network of fault lines, Haiti is one of the most earthquake-prone nations on Earth. In 2021, the Nippes earthquake became the latest to devastate the country, and today, researchers are still piecing together the timeline of seismic events which unfolded during the earthquake. Through their research, Professor Jeremy Maurer and colleagues at Missouri University of Science and Technology have described how the Nippes earthquake originated, shifted, and ruptured a major fault line, triggering numerous ‘afterslip’ events in the following days.

Prof. Nelson Gekara | The Guardians of the Gut: A New Frontier in the Defence Against Viruses

Our gut contains a sleepless army, creating a hostile environment for pathogens, and helping to fortify our body’s immune defences. It may surprise you to learn that this army isn’t even human in nature, but is bacterial. The trillions of bacteria that naturally live in our gut, known as the gut microbiota, form an important component of our overall immunity against infectious disease. While bacteria can also cause disease, beneficial bacteria naturally colonise available spaces in our body, such as the gut, and play a key role in our immunity and physiology. Research conducted by Prof. Nelson Gekara of Stockholm University in Sweden and colleagues has revealed that these microscopic organisms play a crucial role in protecting us from viral infections, even in organs that are unconnected to the gut. Their study, published in the journal Immunity, uncovers a fascinating link between the gut microbiota and our body’s ability to fight viruses, offering new insights into immune function and the unintended consequences of antibiotic use.

Prof. Diana Jaalouk | Editing DNA and Degrading Proteins: The Tools to Achieve Precision Oncology

Cancer is a daunting healthcare challenge, and is still affecting millions worldwide, despite the enormous research resources that have been directed at finding effective treatments over the past decades. Many anti-cancer treatments remain poorly specific for the tumours they are intended to treat, and often suffer from modest efficacy and serious off-target effects. Part of the problem is the inherent variability between many tumours and their resulting unpredictable responses to standard chemotherapy. However, the latest advancements in precision oncology may be the start of a new paradigm, potentially providing targeted therapeutic payloads that can successfully address the specific and unique issues underlying a given patient’s cancer. Researchers such as Prof. Diana Jaalouk and her colleagues at the American University of Beirut in Lebanon are pioneering innovative tools that are changing the way we understand and treat this complex disease. Two remarkable recent technologies, CRISPR-Cas9 and PROteolysis TArgeting Chimeras (or PROTACs for short), are at the forefront of this precision revolution. While distinct in their approach, these tools share a common goal: targeting cancer with precision and minimizing harm to healthy cells. Together, they are set to reshape the therapeutic landscape.
