About this episode
Dietary antioxidants, such as vitamin C, are known to reduce the negative effects of toxins in mammals by preventing cellular damage caused by reactive oxygen species. However, it is not known whether these antioxidants have a similar protective effect in insects. A team led by Dr Barry Pittendrigh at Purdue University have investigated the adaptive responses of fruit flies to insecticide exposure in the presence of vitamin C. Their work has exciting implications for reducing the threat of insecticide resistance in insect pests.

Energy is vital for life. It allows important functions to occur in living systems, from the molecular level to the scale of the whole organism. Dr Helen Greenwood Hansma, from the University of California in Santa Barbara, believes that the types of energy used in living cells can provide clues to help us understand the origins of life. In her recent research, she explores how mechanical energy could have driven the processes that gave rise to early life in the absence of chemical energy.
Herman and Chomsky’s propaganda model is among the most renowned academic contributions to the study of journalism. Although it offers valuable insight into news content and how the media industry operates, it mostly ignores an important step in the production of news: what happens in the newsroom. Dr Tabe Bergman, an Assistant Professor at Xi’an Jiaotong-Liverpool University and Deputy Head of the University’s Media and Communication department, recently assessed practices in the newsroom, with the aim to supplement the propaganda model.
Dr Samantha Dolan – Investigating Facilitators and Barriers to Electronic Immunisation Registry Implementation in Tanzania and Zambia
Digital health interventions have the potential to revolutionalise the management of health information. Despite reduced costs and increased accessibility of technology across the world, the implementation of digital health technologies in low- and middle-income countries has been less than optimal. Dr Samantha Dolan at PATH and the University of Washington and her colleagues investigated the perceived facilitators and barriers to electronic immunisation registry implementation in Tanzania and Zambia, and provide important recommendations for future practice.
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.
