Salk Institute scientists analyzed almost 200 cannabis genomes to create the most comprehensive, high-quality, detailed genetic atlas of the plant to date. The atlas reveals unprecedented diversity and complexity within the species, sets the stage for advances in cannabis-based agriculture, medicine, and industry, and builds on a 10,000-year long relationship between humans and cannabis, showing that cannabis can be as important as other crops like corn or wheat.

A virus responsible for damaging cotton crops across the southern United States has been lurking in U.S. fields for nearly 20 years – undetected. According to new research, cotton leafroll dwarf virus (CLRDV), long believed to be a recent arrival, was infecting plants in cotton-growing states as early as 2006.

UH scientists helped pioneer a new way to breed climate-resilient crops faster by combining plant genebank data with climate and DNA analysis. The method, tested on sorghum, could speed up global efforts to secure food supplies in a changing climate.

In a review in The Philosophical Transactions of the Royal Society B, Stephen Long, a professor of crop sciences and of plant biology at the University of Illinois Urbana-Champaign, describes research efforts to “future-proof” the crops that are essential to feeding a hungry world in a changing climate. Long, who has spent decades studying the process of photosynthesis and finding ways to improve it, provides an overview of key scientific findings that offer a ray of hope.

New archaeological findings along a little-known medieval wall in eastern Mongolia reveal that frontier life was more complex than previously believed. Excavations show evidence of permanent habitation, agriculture, and cultural exchange, suggesting that these walls were not solely defensive structures but part of a broader system of regional control and interaction during the Jin dynasty.

Forest-based agroforestry can restore forests, promote livelihoods, and combat climate change, but emerging agroforestry initiatives focusing only on tree planting is leading to missed opportunities to support  beneficial outcomes of forest management, a Yale-led team of scientists found.
