Nepal’s mid-hills are places where farming has long meant working with the landscape rather than against it. Terraces cut into steep slopes turn difficult ground into fields for maize, millet, rice and other crops, with generations of farmers maintaining the walls and soil that make cultivation possible. But the balance between people, farmland and wildlife…

He climbed inside a huge ceramic…
In 1980, conservationists began an ambitious ecological restoration programme on Santa Cruz Island, off the coast of Southern California. The main goal was to remove tens of thousands of feral sheep whose uncontrolled grazing was damaging native plants and threatening wildlife habitats. Over the next seven years, organised eradication efforts dramatically changed the island’s landscape….

The finding emerged from research into methane pyrolysis, a process that splits methane into hydrogen and solid carbon instead of producing CO2…
Restoring damaged land can look straightforward on paper: plant trees, repair soils and wait for vegetation to return. On the ground, the work is less predictable. Young plants have to survive drought, poor soils, fire, grazing and the other pressures that caused landscapes to deteriorate in the first place.Mexico’s National Forestry Commission, known as CONAFOR,…
Max Planck, the German physicist whose work helped lay the foundation for quantum theory, believed that science was ultimately a search for deeper and more fundamental truths. His reflections on scientific discovery reveal how strongly he valued the pursuit of universal principles rather than simply solving individual problems. In his Scientific Autobiography, Planck wrote about…
Four concrete barriers blocked the way for salmon that once swam freely between the Pacific Ocean and the high desert reaches of Oregon and California for more than a hundred years. The dams were removed in 2024 as part of one of the largest dam removal projects in U.S. history, letting the river flow freely…

This is a fusion plasma, the same kind of matter that powers the Sun, and it is notoriously difficult to control.In a recent…
