A sonar station that counts salmon traveling up the Yukon River in Alaska malfunctioned this year, resulting in a smaller allowed catch, officials say. Russ Holder, federal fisheries manager for the Yukon, said the king salmon season looked like one of the poorest we've ever had, the Anchorage Daily News reported. In hindsight, it doesn't look as poor as those numbers indicated to us, he said. Because of the lower catch, enough fish got as far as the Canadian section of the river to fulfill a...

A team of researchers from the University of Alcalá de Henares (UAH) has shown scientifically that human beings can develop echolocation, the system of acoustic signals used by dolphins and bats to explore their surroundings. Producing certain kinds of tongue clicks helps people to identify objects around them without needing to see them, something which would be especially useful for the blind."In certain circumstances, we humans could rival bats in our echolocation or biosonar...

German scientists have discovered bats can use echolocation in identifying characteristics of other individual bats' voices to recognize each other. Researchers from the University of Tuebingen and the University of Applied Sciences in Konstanz said they first tested the ability of four greater mouse-eared bats to distinguish between the echolocation calls of other bats. After observing the bats learned to discriminate the voices of other bats, then they programmed a computer model that...

A new study shows that bats use sound for more than direction. Scientists from the University of Tuebingen, Germany and the University of Applied Sciences in Konstanz, Germany have found that bats have the ability to recognize each other using sound. The researchers began their study by testing how well four greater mouse-eared bats could distinguish between echolocation and the calls of other individual bats. They noted that the bats accurately identified the calls of other bats....
