Scientists say a strengthening super El Nino is loading the atmosphere with heat and may delay the peak impact until 2027. That lag, combined with greenhouse-driven warming, could intensify extreme weather and push global temperatures to a new record.

Bats rely on echolocation to move through the dark and hunt insects. They send out high-pitched sound waves that bounce off nearby objects and return as echoes which helps them judge where things are.

Birds may sound different depending, but scientists have now found that many of their songs are built from the same basic set of sound patterns. A new global study has identified eight recurring motifs that appear in the songs of thousands of bird species.

For years, scientists have believed one major reason insects are almost absent from the ocean is simple physics: their air-filled bodies would collapse under deep-water pressure. But a tiny insect larva living in Africa's Lake Malawi is challenging that idea in a surprising way.

For centuries, humans have searched for ways to extend life, first through medicine that prevented early deaths and later through research aimed at slowing the biological processes associated with aging. But even if scientists eventually found a way to stop many age-related problems, the body might still face limits built into its own cells.

Sperm whales may be among the largest predators in the ocean, but even these enormous hunters face a surprisingly simple problem when they rest: staying underwater. According to a study published in Current Biology, researchers have now found that the whales appear to release bubbles as they sleep, reducing their buoyancy just enough to remain suspended beneath the surface instead of drifting upwards.

Across the globe, there are approximately 200,000 to 275,000 glaciers that hold 69% of the world's fresh water. They are found in every continent except Australia and are in heavy concentrations in the Arctic, Alaska, and Antarctica along with high mountain ranges like the Himalayas and Andes.

A spray-based treatment may help avocado farmers reduce climate-related crop losses, according to new research from Israel. There is, however, an important caveat.

Governments have a crucial 30 to 50 year window to plan for rising sea levels using dependable computer models, before Antarctic ice melt becomes far harder to predict.

Every year, thousands of Olive Ridley sea turtles appear along Odisha's shoreline after spending much of their lives travelling across the Indian Ocean. Their arrival is so regular that it has long raised the same question: do they return to the same stretch of coast after disappearing for decades, scientists have been trying to answer that mystery for years.
