NEW YORK (AP) — Horses whinny to find new friends, greet old ones and celebrate happy moments like feeding time. How exactly horses produce that distinctive sound — also called a neigh — has long eluded scientists. The whinny is an unusual combination of both high and low pitched sounds, like a cross between a
For about six months, NASA’s Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the Red Planet
Saturn’s largest moon, Titan, is one of the solar system’s oddities. Now, researchers have unlocked key insights about this mysterious moon, including how it came to be. The answer may also shed light on the origin of Saturn’s beautiful rings. Shrouded in a thick haze, Titan is about half the size of Earth and even
Each morning begins with the same sound – birds singing before sunrise. A new study on zebra finches explains this behavior with remarkable clarity. The researchers found that early singing isn’t random joy, but a rebound from silence. During the night, darkness suppresses the birds’ urge to sing. When the first light appears, that urge
an international collaboration of cosmologists has reached a new level of precision in measuring the Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various measurement techniques, refining them to produce a unified and highly accurate value.
It’s a tail as old as time. Scientists may have discovered the world’s oldest butthole after unearthing the nearly 300-million-year-old impression of a reptile’s backend in Germany, per an upcoming study in the journal Current Biology. “Such soft-tissue structures are extremely rare in the fossil record – and the further back we look in Earth’s
In the rugged hills of western Iran, an ancient discovery is challenging everything we thought we knew about early human societies. What was once considered a minor site has now revealed a fascinating glimpse into the complex administrative systems of prehistoric times. At Tapeh Tyalineh, archaeologists uncovered thousands of seal impressions, figurines, and tokens that

Humans have changed a lot over the past few hundred millennia. We evolved from ancient apes, which are believed to have in turn evolved from sea creatures that existed in the distant, distant past, and Homo sapiens have only existed for a paltry 300,000 years. Some animals, however, have remained almost exactly the same for
