University of Cambridge researchers have developed ultra-thin, flexible ‘artificial leaves’ that generate clean fuel from sunlight and water. The organs take inspiration from the process by which plants convert sunlight into food: photosynthesis. Because they are independent devices that are light enough to float, they can be used to generate a sustainable alternative to gasoline on a large scale without taking up space on the ground. According to a university press release, this is the first time that clean fuels have been generated on water and the technology can be…

The birds no longer sing, and the herbs no longer grow. The fish no longer swim in rivers that have turned a murky brown. The animals do not roam, and the cows are sometimes found dead. The people in this northern Myanmar forest have lost a way of life that goes back generations. But if they complain, they, too, face the threat of death. This forest is the source of several key metallic elements known as rare earths, often called the vitamins of the modern world. Rare earths now reach…

WASHINGTON — From replicating the process that fuels the sun to harnessing the scorching temperatures beneath our feet, scientists, companies, and venture capitalists are betting on high-tech ways to power the planet without emitting greenhouse gases. These “moon launch” technologies are likely to be a topic of discussion when delegates meet at the UN climate talks in Scotland, which begin on Sunday, to find out how to speed up the shift away from fossil fuels. While traditional clean energy sources such as solar and wind are expected to play a…
