Despite efforts to pivot toward renewable sources of energy, oil remains the backbone of modern society. It provides fuels for heat and transportation, and chemicals for everything from plastics to pharmaceuticals. But all these uses require separating crude oil into its various components. That separation process—which traditionally relies on heat—takes a tremendous amount of energy and accounts for roughly 1% of global greenhouse gas emissions each year. Hosted on Acast.

Researchers from the Marine Ecology Group in UCC in Ireland collected feathers from Manx shearwaters, a seabird species thought to be at risk from oil pollution. The researchers examined the feathers to see how quickly water would pass through after exposure to increasing concentrations of oil. Feathers were also assessed under high-powered microscopes to examine structural changes after contamination. Hosted on Acast. See acast.com/privacy for more information....

On quiet nights across large swaths of the African bush, you may hear a series of whooping calls in the distance. This unique sound is the long-distance vocalisation used by spotted hyenas ( Crocuta crocuta ) to communicate with each other. For hyenas, it’s advantageous to know who is calling before deciding to respond. They don’t treat every member of their group the same – and the caller could even be an intruder in their territory.

Climate change has already increased global temperatures, greatly increasing extremes. This will continue unless greenhouse gas emissions are reduced to “net-zero”. The 1.5°C target of the Paris Agreement requires emissions reductions of around 50% in the next 10 years . Hosted on Acast. See acast.com/privacy for more information.

More than half of federal funding for “climate-smart” agriculture in the US goes to farming practices that are unlikely to reduce greenhouse gas emissions – and in some cases, would even increase them, according to a new report by the non-profit Environmental Working Group (EWG).

Agricultural producers face dual challenges of increasing output for a growing world population while reducing negative effects on the environment. Digital technologies and artificial intelligence can facilitate sustainable production, but farmers must weigh opportunities and risks when deciding whether to embrace such tools. Hosted on Acast.

Agriculture involves a difficult balance between food production and environmental impact. For example, fertilisers can help to achieve good crop yields, but over-using them produces greenhouse gas emissions and pollution . Hosted on Acast. See acast.com/privacy for more information.
Crop micronutrients refer to essential elements that plants require in small quantities for proper growth, development, and overall health. While plants need these nutrients in smaller amounts compared to macronutrients like nitrogen, phosphorus, and potassium, they are nonetheless critical for various physiological processes.
