An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place — to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world. …

To navigate the world, we all shimmy like these electric fish Read More »

Scrape, cluck, lay eggs — that’s it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental conditions — a finding that points beyond the experiment with roosters and could …

The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo’s underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only …

Noctilionoid bat species evolved wildly different faces as they adapted to exploit diverse food sources — including insects, fruit, nectar, blood and fish. New research shows that those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position. ​Noctilionoid bat species evolved wildly different faces as they adapted to exploit diverse …

Scientists at NCAR have identified two entirely different modes of hurricane rapid intensification. The findings may lead to better understanding and prediction of these dangerous events. ​Scientists at NCAR have identified two entirely different modes of hurricane rapid intensification.
