Most butterflies survive for only a few weeks after reaching adulthood. But scientists have now identified a group of tropical butterflies that can live for almost a year while showing little sign of physical decline, a discovery that could help researchers better understand how healthy ageing evolves in nature.

In 1999, China launched their ambitious tree-planting campaign to combat desertification and to restore degraded landscapes. This initiative is widely regarded as one of the world's largest ecological restoration efforts, with billions of trees planted across China's arid regions to increase vegetation cover and reduce soil erosion.

When New Zealand imported stoats from Britain in the late 1800s, the goal seemed simple: to control the sharp increase in the rabbit population that was devastating sheep pastures. However, despite the true intentions, scientists now regard the move as one of New Zealand's biggest ecological blunders, as the introduction of the predator helped drive the native birds into extinction rather than helping with the rabbit problem.

Trees introduced outside their native habitats often struggle to adapt, but a few go on to reshape entire landscapes. One of those species is the black locust tree, which is an originally North American tree that has become one of the key resources of Hungary.

A strain of epizootic haemorrhagic disease virus, first detected in Spain in autumn 2022, is causing serious disease in red deer. Scientists have found new evidence that the virus can damage the brain, lungs, and kidneys of infected animals.
