The water cycle, also called the hydrologic cycle, is the continuous movement of water on, above, and below the surface of Earth. The total amount of water on Earth changes very little on human timescales. What changes is its form and location. Water exists as liquid in oceans, rivers, lakes, and soil; as solid ice…
Jealousy arrives like a verdict. In the moment it feels certain: someone is taking what is yours, or is about to. Science treats it more narrowly. Jealousy is a reaction to a perceived threat that a third person will take or change a relationship you already have. That is why psychologists separate it from envy….

Your body produces some antioxidants on its own, while others come from foods such as fruits, vegetables, whole grains, nuts and seeds. But antioxidants are often misunderstood. They are sometimes described as substances that simply “fight” aging or…
A mini-split that suddenly blows cooler air, goes quiet outside, or sends up a cloud of “smoke” in January is usually doing its job. In heating mode the outdoor coil is the cold part of the system. It pulls heat from outdoor air. When that coil is colder than freezing and the air is damp,…

With its towering T-shaped pillars carved with strange and powerful symbols, the site challenges everything we thought we knew about the origins of civilization. Only a fraction has been uncovered.

Almost everything people “know” about Jesus arrives through worship, not through a file in an archive. That is not a slight. It is the first fact a historian has to live with. The man at the centre of Christianity left no letters that survived in his name. No Roman court transcript of his trial has…
Large language models can answer questions, write articles, generate code and analyze information in seconds. But behind that convenience is a physical infrastructure that consumes electricity, requires cooling and depends on enormous data centers. That has created a growing question around artificial intelligence: How much does using AI actually cost the environment? The answer is…
