Elk are social ungulates, so close contact such as nuzzling may reflect affiliation, grooming, recognition, or another context-dependent interaction. A single trail-camera clip can show an intriguing behavior, but it cannot establish the animals' relationship, emotions, location, or a general rule about elk.
China is testing AI weather-forecasting systems as extreme weather raises the need for faster, more capable predictions. These models learn patterns from historical data, while traditional numerical systems simulate atmospheric physics, giving each approach distinct strengths and limitations.
Jackie became a widely followed wild bald eagle through the Friends of Big Bear Valley webcam, and reports of her death highlight both public connection to wildlife and the broader conservation story of her species.
How people in France can choose legitimate solar-eclipse viewers, check the applicable safety standard, recognize counterfeit risks, and watch the Sun without relying on ordinary sunglasses or cameras.
Understanding how earthquakes occur, the science behind seismic activity, and their impact on human societies and the environment.
A plain-English explainer on solar eclipses, what actually happens when the Moon blocks the Sun, why total eclipses are so rare at any given spot, and how to safely watch one.
An exploration of meteorology and climate patterns that drive our daily weather and long-term climate systems, including forecasting techniques and atmospheric processes.
Rare earth minerals power everything from electric cars to fighter jets, and China dominates their supply. A new American investment in an Australian mine is part of a high-stakes race to break that monopoly.
A plain-English explainer on the radical study suggesting life on Earth may have originated from non-living matter twice, what the evidence is, and why it matters for the search for life elsewhere.
How a few seconds of warning before strong shaking arrives can save lives, why P-waves beat S-waves, and how Japan, Mexico, and the US run the world's earthquake early warning networks.
An explainer on NASA's plan to keep Voyager 2 operating into its 49th year — how a 1970s probe is kept alive, what powers it, and why an ageing spacecraft keeps teaching us.
An explainer on Movile Cave, the Romanian ecosystem sealed from the outside world for 5.5 million years, how its strange life gets energy without sunlight, and why isolated worlds matter.
Why the Perseids light up August skies every year, what comet Swift-Tuttle has to do with them, and how to actually watch a meteor shower for the best chance of seeing shooting stars.
An explainer on what happens when a SpaceX rocket stage crashes into the Moon — why it makes a crater, what the impact reveals, and the small but real problem of space junk beyond Earth orbit.
An explainer on scandium — the obscure rare metal driving a Pentagon-backed Australian mining push — covering what it is, why aerospace and defence want it, and why Australia's deposits suddenly matter to U.S. supply chains.
An explainer on the World Meteorological Organization — what the WMO is, how it coordinates global weather and climate data, why its names trend during major weather events, and how it differs from national weather services.
A straightforward explainer on neurons — what axons, dendrites, and synapses do, how action potentials fire, and why these cells are the foundation of thought and movement.
Vaccines train your immune system to recognize pathogens without making you sick. An accessible look at mRNA, viral vectors, and the adaptive immune response.
Indonesia sits on the Pacific Ring of Fire, home to 130 active volcanoes. How the archipelago's geology shapes its culture, economy, and constant negotiation with disaster.
Germany is preparing for a near-total lunar eclipse on August 28, 2026. How lunar eclipses work, why the moon turns red, and what makes this one the most spectacular of the decade.
