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…
Nikola Tesla (Image: Wikipedia) Being copied usually provokes anger. A line widely credited to Nikola Tesla suggests a different reaction entirely. “I don’t care that they stole my idea,” it goes. “I care that they don’t have any of their own.” Rather than focusing on the theft itself, the line shifts attention toward something Tesla…
Scientists have uncovered plastic pollution in one of Earth’s most isolated environments, challenging the long-held belief that the deep ocean remains largely untouched by human activity. Analysing animals living more than 2,000 metres beneath the sea, researchers discovered that 92% contained microplastics, offering some of the clearest evidence yet that plastic waste has reached even…
In 2003, scientists began closely examining how an old hunting technique called fladry could be transformed into a modern, non-lethal tool for reducing conflicts between wolves and livestock. Originally used in parts of Eastern Europe and Russia to guide wolves toward traps, lines of hanging flags were later tested as a way to keep wolves…
Cockroaches have a reputation problem. Most people picture them scurrying across a kitchen floor, but that image only applies to a tiny fraction of the group. Earth is home to thousands of cockroach species, and the overwhelming majority live far away from human homes, spread across forests and other natural habitats where they quietly go…
