 Urban areas generate an immense quantity of organic waste daily—ranging from leftover food and yard trimmings to animal manure from zoos. Traditionally, this waste ends up in landfills, where its decomposition releases methane, a greenhouse gas significantly contributing to climate change. However, a new study highlights a more sustainable solution: transforming urban waste into fertilizer for urban farming. Researchers from the University of California, Davis, and the University of Wisconsin-Madison have demonstrated how organic waste can improve soil health and potentially enhance the quality of urban-grown crops. Organic Waste and the Urban Challenge Organic waste makes up a substantial portion of municipal waste streams in major cities. Items like discarded food, plant debris, and manure are rich in nutrients vital for plant growth, such as nitrogen and carbon. Instead of viewing this waste as a disposal problem, cities can see it as a valuable resource. Properly processed o...

 In a groundbreaking study, scientists from Stanford University have made a pivotal discovery that helps explain long-standing mysteries about Antarctica’s massive ice sheets. This new finding could transform our understanding of how the ice sheet behaves under the stress of climate change, providing critical insight into future sea level rise. For decades, researchers have puzzled over discrepancies in models predicting the flow of Antarctic ice. While surface observations suggested certain regions should move faster due to their slope and gravity, they remained surprisingly stable. Scientists speculated there was a missing factor that had not yet been accounted for. Now, Stanford’s team believes they’ve found the answer. Their research focuses on the presence of a hidden geological feature beneath the ice: a layer of ancient, porous rock that acts as a kind of sponge, trapping water at the base of the ice sheet. This subsurface water regulation helps stabilize the ice sheet by ...
