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…
The night sky has inspired people for thousands of years, but scientists now say it could look very different in the future. The researchers at the European Southern Observatory (ESO) warn that ambitious plans to launch huge numbers of satellites into Earth’s orbit could make the night sky much brighter than it is today.While many…
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…
Scientists are checking if an underwater curtain is what will keep an Antarctic glacier from slowly melting due to warm water. The proposal is to install an underwater curtain about 80 kilometres long and up to 150 metres high in front of the Thwaites Glacier in West Antarctica. Between January and March 2026, an expedition…
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…
For thousands of years, humans have relied on the movement of the Sun to understand the passage of time. But one ancient habit may have quietly shaped something people see every day: the direction in which clock hands move. The familiar clockwise motion of modern clocks was not decided by engineering rules or scientific necessity….
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…
As heatwaves become more frequent and intense, cities around the world are searching for ways to stay cooler without relying solely on energy-intensive air conditioning. Medellín, Colombia, has emerged as one of the world’s most celebrated examples of nature-based urban cooling. Through its Green Corridors programme, the city planted around 880,000 trees and more than…
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…
Coastal flooding that was once considered unusual is becoming a more familiar part of life in many parts of the world, and rising sea levels appear to be a major reason why. A new international study suggests that the gradual increase in ocean height has fundamentally changed how often exceptionally high sea levels occur, making…
