Engineers at the University of California San Diego have developed a spray-on polymer coating to help plants resist bacterial infections and survive drought, which could strengthen global food security. Bacterial infections are a growing threat to agriculture, causing major crop losses worldwide. Rising temperatures are allowing pathogens to expand into new regions, increasing crop exposure to infections. Researchers developed an antibacterial coating that can be sprayed directly onto plant leaves to combat this challenge, offering a promising solution to enhance crop resilience and food production in the face of climate change.

Environmental News Network – When Spending Less Delivers More Climate-Friendly Nutrition
A global study from Tufts University published in Nature Food found that eating healthy can save money and produce fewer greenhouse gas emissions compared to current food choices. The study identified locally available foods that meet nutritional needs with low emissions and costs, challenging the belief that climate-friendly eating is expensive. Lead researcher William A. Masters emphasized the importance of considering both cost and emissions when making food choices, highlighting that cheaper food options generally have lower emissions within each food group. This research provides valuable insights for climate solutions experts looking to promote sustainable and affordable food choices.
