Until recently, the color variations observed in the petals of Saintpaulia were attributed to periclinal chimera or the influence of genetically distinct cell layers. Now, a new study by researchers from Japan has identified a single gene called SiMYB2 that regulates petal colors in Saintpaulia by producing two distinct mRNA transcripts. This study lays the foundation for future horticulture-related research and can aid the deliberate breeding of patterned flowers.
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.
A new study introduces a machine learning tool that combines satellite imagery and weather data to monitor chickpea crop health. The system accurately estimates Leaf Area Index (LAI) and Leaf Water Potential (LWP) across commercial fields, helping farmers make smarter irrigation decisions and improve yields. This research marks the first large-scale application of such technology in chickpea farming.
University of Utah geoscientist Gabriel Bowen’s analyzed of carbon and oxygen isotopes of sediments recovered from the bed Utah’s Great Salt Lake. His findings document profound human-driven environmental changes arising from agriculture and rail causeway.
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.
