Huntington disease (HD) is an inherited and progressive neurological disorder which is currently fatal. Dr James E. Goldman and Dr Osama Al-Dalahmah, both at Columbia University, USA, are utilising new techniques in molecular biology to better understand the brain pathology associated with HD. Their vision is to develop therapeutics that can slow the progression of the disease, and ultimately, treat and even prevent it.

Antimicrobial resistance (or AMR for short) is a pressing global health challenge that poses significant risks, particularly in low- and middle-income countries. The extensive research conducted by Saffiatou Darboe of the London School of Hygiene and Tropical Medicine, The Gambia, and her colleagues, has been pivotal in understanding and addressing this issue within The Gambia and other regions in sub-Saharan Africa. This episode delves into four comprehensive studies conducted by Darboe and colleagues, shedding light on the impact of AMR, the importance of antibiograms, and specific outbreaks of resistant pathogens.

As cannabis prohibition begins to unravel across the world, cannabis use has become more common and normalised. Researchers are assessing the impact of this on vulnerable populations, such as pregnant women. Strikingly, cannabis is among the most commonly used substances during pregnancy, raising serious concerns about its effects on unborn children and the long-term consequences this could have. Prof. Miranda Reed of Auburn University, and colleagues, have assessed how cannabis exposure in the womb can affect brain development and cognitive abilities, such as memory.
