Hawaii: In 1955, Hawaii released a cannibal snail to control another invasive snail, but the predator instead helped push the islands’ rare native tree snails toward extinction

Still, the outlook for Hawaii’s snails is uncertain, symbolizing a new era in the conservation of endangered species. In 1955, wildlife officials in Hawaii released a meat-eating “cannibal” snail to control an invasive pest. But the plan went terribly wrong. Instead of eating the pest, the predator turned on the islands’ rare native tree snails,…

A silent coral reef came back to life after scientists played recordings of healthy reefs underwater |

The decline of coral reefs is often described through bleaching events, rising sea temperatures and fading marine life. Less attention is paid to something that disappears at the same time: sound. A healthy reef is rarely quiet. Snapping shrimp, feeding fish and countless other marine animals create a constant underwater backdrop that helps young fish…

Feral cats erased 11 native species from this Australian island. Scientists are bringing back two truffle-eating marsupials to rebuild it |

Two threatened marsupials are being reintroduced to the Shark Bay World Heritage area in order to advance species conservation and ecosystem restoration. A new study from Edith Cowan University (ECU) confirmed that the presence of fungal food resources is important for supporting this effort.The study published in the journal Ecosystems and led by Edith Cowan…

AI can become more biased than humans while choosing who gets hired; study finds |

Artificial intelligence is increasingly being trusted to help employers screen CVs, rank candidates and even conduct early-stage interviews. The promise is simple: AI can process thousands of applications quickly, reduce administrative workloads and, in theory, make hiring decisions more objective than humans. According to a recent review by MIT Technology, based on the 2024 study…

Alaska’s crystal-clear rivers are turning vivid orange: Metal pollution is creating ‘rusting’ waterways, threatening wildlife, habitats and drinking water |

Image Credit: Josh Koch/USGS In the heart of Alaska’s wilderness, a transformation is happening because of which the scientists and local communities are deeply concerned. The once-fresh, crystal-clear rivers of the Brooks Range in northern Alaska are rapidly turning into a vivid, rusty orange colour. This transformation, visible even from space, is not the result…

AI cracks a mystery from 1939 that mathematicians couldn’t solve for decades; the answer was hidden in 216 characters |

For decades, solving the world’s hardest mathematical problems has been considered a uniquely human pursuit, requiring imagination, persistence and the ability to explore ideas beyond established methods. Artificial intelligence, meanwhile, has largely been viewed as a tool for computation and analysis. A Harvard mathematician’s collaboration with an experimental AI model has gained widespread interest after…
