About this episode
There are over 3,600 established cell lines from 150 different species that can be used for scientific and medical research. In two recent studies, Dr Ruth MacKinnon and her team from St Vincent’s Hospital in Melbourne used multiple molecular methods to investigate changes in the way the genes are organised in two types of these cells. They demonstrated the importance of using multiple complementary methods and found that these cells can continue to evolve in the laboratory. They also uncovered evidence of a previously unreported process called ‘centromere capture’ which may be involved in the evolution of cancer cells.

Dr. Serena Kuang | Inside the Kidney’s ‘Countercurrent’ Mystery: A New Model for Teaching and Studying Water Balance
Our kidneys filter blood to remove waste and can regulate water balance. We’ve all experienced that when we’re thirsty urine becomes concentrated, signalling us to drink more water. When we drink excess water, we urinate more frequently, and the urine is diluted. The kidneys’ ability to concentrate or dilute urine according to our body’s need relies on countercurrent multiplication (or CCM), a complex process that generates a salt concentration gradient in the kidney. However, CCM is challenging to teach and understand. Dr. Serena Kuang, a researcher and educator at Oakland University William Beaumont School of Medicine, has developed a more understandable CCM model and clears up errors in existing explanations making CCM easier to understand and teach.
Dr Neil Cunnigham | The Heart of the Matter: How Simulation Reflects Clinical Stress in Critical Care Training
In the high-stakes world of critical care, medical professionals are frequently called upon to perform life-saving procedures under intense pressure. Among these, airway intubation stands out as one of the most critical and technically demanding tasks. This procedure, which involves inserting a tube into a patient’s airway to ensure that they can breathe, is often performed in emergency situations where seconds count. The ability to intubate swiftly and accurately can mean the difference between life and death. However, this task is also fraught with stress, particularly for trainees who are still developing their skills. To better understand how these trainees cope with the stress of intubation, Dr Neil Cunningham of the University of Melbourne and colleagues conducted a groundbreaking study comparing physiological stress responses in simulated and clinical environments. Their findings offer valuable insights into the effectiveness of simulation-based training, which has become a cornerstone of medical education.
Dr. Ivy Razmus | Reducing Pressure Injuries in Hospitalized Children and Babies
The development of pressure injuries in hospital patients is a regular occurrence, and certain areas of the body are more susceptible. Although there is abundant research on pressure injuries in adult patients, studies relating to infant and child patients are lacking. Dr. Ivy Razmus at the University of Detroit Mercy has conducted extensive research on the prevention of pressure injuries in patients under the age of 12 years. She highlights the crucial role of advanced practice nurses in managing this widespread problem.
Pulque: The Ancient Drink That Could Shape the Future of Health
Pulque, an ancient Mexican beverage, is making waves in the scientific community—not just as a cultural relic, but as a potential health-boosting powerhouse. A team of researchers, including Prof. Rogelio Valadez-Blanco, Dr. Yesica Ruiz-Ramírez, and Prof. Paula Guadarrama-Mendoza, from Universidad Tecnológica de La Mixteca, has been investigating the hidden potential of the bacteria found in this traditional drink. Their findings suggest that pulque’s naturally occurring lactic acid bacteria could play a key role in promoting gut health and even combating harmful pathogens that cause foodborne illnesses.
