Researchers studying Scotia Sanctuary in south-eastern Australia found that 8 years after reintroduced mammals were given access to areas, the communities of insects emerging from the soil had changed. The mammals, including greater…

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…

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,…

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

The 77-year-old, widely known as the ‘Snake Doctor,’ discovered the ‘Mangshan pit viper’ and…

Ella Zhang and Gillian Leung, students at Havergal College in Canada, created ‘ToothTint’ as a school project that uses a natural pigment to change colour in response to conditions inside the mouth. The idea…

PC: California’s La Brea Tar Pits & Museum A small Ice Age toad hidden in the collections of California’s La Brea Tar Pits has emerged as a new species to science, giving researchers another way to read the environmental history of ancient Los Angeles. ‘Spea labreae’, the extinct spadefoot toad, was identified when Dr Alberto…

This behaviour has often been described as elephants visiting a “grave” or mourning their dead. But scientists say the reality is more complicated. An elephant herd comes across the remains of another elephant. Instead of simply walking past, some animals slow down, approach the bones, touch them with their trunks and sniff them. In some…

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…
