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.

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.

In recent years, many researchers have been investigating the associations between wage, education, and productivity, to gather valuable insight that could guide business decision-making. Professor Qiao Wang at Capital University of Economics and Business in Beijing has recently carried out a study specifically exploring the possibility that the motivation and productivity of business managers could be affected by their levels of education.

Weaning is an important time in the pig lifecycle, and changes in diet and environment can lead to unbalanced gut microbiota and pathogen colonisation. Prof. Luciana Rossi, Dr. Matteo Dell’Anno from the University of Milan, and Dr. Maria Luisa Callegari from Catholic University of Sacred Heart, have been investigating the impact on gut bacteria of adding natural compounds known as tannins to piglet food. Importantly, they found that tannins do affect the gut bacteria; with increases seen in bacteria associated with improved growth and gut health, and in particular, those that produce butyrate – a substance with proven health benefits.
