The Physicians Committee for Responsible Medicine, a nonprofit national medical ethics group, applauds Colorado State University for its decision to shutter a nutrition study for which the university had approved the killing of 17,766 animals. The study, funded by the U.S. Department of Agriculture and the university, claimed to investigate the effect of legumes on the human gut microbiome. Public records reveal the primary investigator had to date used 1,587 mice.

Much previous work in the social sciences has involved researchers – often but not always from the Global North – collecting data from rural communities in the Global South on a wide range of topics from public health to education, agriculture and climate change. Such ‘helicopter’ research is not good practice as it often involves an asymmetry of power and knowledge that invariably disadvantages local communities. So how can research be made more equitable? This is the topic of an analysis undertaken by Jasper Knight from the Wits School of Geography, Archaeology and Environmental Studies, who is also chair of the University’s Non-Medical Ethics Committee, in a new research study published in the International Journal of Qualitative Methods.

A research team found that chlorogenic acid (CGA) improved ovarian function, restored hormonal balance, reduced oxidative stress, and partially normalized disrupted gut microbiota in a mouse model mimicking age-related ovarian decline.
