Prime Minister Mark Carney said Tuesday that trade talks with the United States can resume only when Washington “starts being serious” and stops posting memes and insults. Speaking to reporters in Ottawa after Monday’s federal byelections, Carney said there is still room for a deal that is “mutually beneficial” and “respects Canadian sovereignty.” “When the…
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…

The search for intelligent life beyond Earth is a real scientific program. Radio surveys and related work at places such as the Green Bank Telescope, the Allen Telescope Array, Parkes, and Breakthrough Listen look for signals that do not look natural: narrow radio tones, pulsed beacons, and other technosignatures. This article asks one question. What…
Things in Canada still cost more than they did a few years ago. They are just not going up as fast. In July 2026, the average price of everyday stuff was 3.0 percent higher than in July 2025. In June, it was 2.8 percent higher. That comes from Statistics Canada. That 3 percent is the…
Rescue teams in Nepal continued searching on Tuesday for hundreds of workers believed to be trapped in hydropower tunnels after catastrophic flash floods struck the Nepal-China border region last week. Nepal’s National Disaster Risk Reduction and Management Authority reported 1,003 recovered bodies as of 1 p.m Tuesday. Later reports citing police and other official updates…
