Melting ice shelves are changing the ocean’s chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change models.
High technology is being deployed to uncover long-forgotten irrigation systems and other features concealed in landscapes that farmers developed hundreds of years ago to nurture their land.
An air quality study has for the first time detected nano-sized particles of air pollution in children’s urine. With a diameter of just 100 nanometers - a thousandth of the width of a human hair - these ultrafine particles are the smallest particles found in air pollution and have been linked to heart disease and respiratory conditions in previous studies.
Mining isn’t the only way to extract valuable metals. Soon, they could increasingly be recovered from waste, reducing the need for new raw materials and helping Europe’s transition to a low-carbon economy.
Sharing best practice farming techniques with farmers from different cultures and traditions could help increase the quality of our soils – a vital step in ensuring that we can grow enough food for people in the coming decades.
Bottom trawling, where fishing boats drag a heavy net along the seafloor, can devastate marine habitats and cause fish stocks to plummet, but scientists have developed new eco-friendly techniques to support the sustainability of an industry employing tens of thousands of people.
New observations may provide alternative explanations for dark energy.
The technology could work with existing infrastructures, says Prof. Lee Cronin
We need to double-check the evidence on dark energy, as it may not exist at all, says Prof. Subir Sarkar.
