Bats Bolster Brain Hypothesis, Maybe Technology, Too

Brown University Decades of research on how bats use echolocation to keep a focus on their targets not only lends support to a long debated neuroscience hypothesis about vision but also could lead to smarter sonar and radar technologies....

Greater mouse-eared bat
2014-07-24 05:09:35

Rayshell Clapper for redOrbit.com - Your Universe Online The manner in which bats use echolocation has long been of interest to scientists, but new research shows that bats use more than echolocation to get around. In fact, the Natural Environment Research Council (NERC) recently announced a new discovery about the greater mouse-eared bat and how it navigates. The greater mouse-eared bat uses “polarization patterns in the sky to navigate…The bats use the way the Sun's light is...

Ripple Effect Used By Bats When Hunting Frogs During Mating Season
2014-01-24 12:56:12

Brett Smith for redOrbit.com - Your Universe Online As male túngara frogs call from their puddles to attract females, they create ripples that spread across the water. According to researchers at the Smithsonian Tropical Research Institute (STRI) in Panama, these ripples are used by other male frogs to assess their competition – and also by bats looking for their next meal. If it sees a bat flying overhead, a male túngara will stop calling – yet ripples continue moving for several...

Bats Rely On Vision To Navigate, Echolocation To Catch Insects: Study
2013-12-13 07:34:50

April Flowers for redOrbit.com - Your Universe Online\ Bats rule the night skies, using the power of echolocation, or reflected sound. More than 1,000 species of echolocating bats exist, compared to just 80 species of nocturnal non-echolocating birds. It seems that normal vision works in tandem with echolocation to give bats an evolutionary edge, however, no one knows exactly how. A new study, led by Arjan Boonman and Yossi Yovel of Tel Aviv University's Department of Zoology, suggests...

Nectar Bat Uses Stealthy Moves To Catch Its Evening Dinner
2013-12-12 15:39:25

Lee Rannals for redOrbit.com - Your Universe Online New research shows the Pallas long-tongued bat is a very stealthy predator when it comes to catching insects. Previously, scientists believed the nectar-feeding bat ate insects in passing, but the latest research shows it targets its moving prey with stealthy precision. The team proved for the first time that the Pallas long-tongued bat uses a stealthier form of echolocation. Echolocation is a physical trait that involves the...

Bats And Dolphins Have Genetic Similarities
2013-09-05 04:58:11

[ Watch the Video: Genetic Similarities In Echolocation Discovered In Bats And Dolphins ] redOrbit Staff & Wire Reports - Your Universe Online Convergent evolution – the evolution of similar traits in drastically different types of creatures – is widespread not just at the physical level but also at the genetic level, according to new research published in this week’s edition of the journal Nature. As part of their study, scientists from Queen Mary University of London...

Echolocation - With Practice, Anyone Can Learn It
2013-08-30 04:23:17

redOrbit Staff & Wire Reports - Your Universe Online Humans can learn to use echolocation to navigate and to find objects, according to new research appearing in the latest edition of the biology journal Proceedings of the Royal Society B. Professor Lutz Wiegrebe of the Ludwig-Maximilians-Universitaet (LMU) Department of Neurobiology and colleagues have now shown how people can acquire the capacity for echolocation, though they emphasize doing so takes a considerable amount of time...

Moths Use Hearing Differently When Picking Up Mating Calls
2013-07-08 14:30:46

Brett Smith for redOrbit.com - Your Universe Online A joint team of Japanese and Danish researchers has found various moth species taking Salt-n-Pepa's suggestion to the next level -- talking about sex in a variety of ways. Lepidopterists have thought for years that moths use their sense of hearing to avoid predation from bats. However, the new study, which was published in Scientific Reports, revealed that their tiny ears are also used to detect the mating whispers of other moths....

UK Team Uses Echolocation To Produce Highly Detailed Bat Maps
2013-07-03 12:42:13

Brett Smith for redOrbit.com - Your Universe Online Using over 15,000 recordings of echolocation sounds gathered from across the UK countryside, researchers from the University of Leeds have rendered the most detailed, large-scale maps of bat distribution in northern England. According to the researchers, the bat maps are especially significant because the animals represent about 25 percent of all of the UK's native mammal species and can be a canary-in-the-coal-mine, ecologically...

Echoes And Algorithm 3D Map Of Room
2013-06-19 08:35:25

redOrbit Staff & Wire Reports - Your Universe Online Researchers have developed a new algorithm that makes it possible to map the shape and dimensions of a room using just a few microphones and a snap of the fingers. Developed at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland, the algorithm models a room using echoes produced from sound, similar to the way in which bats and dolphins emit sounds in order to navigate. This...

Blind People Can Learn To Use Their Inner Bat
2013-05-21 05:51:25

April Flowers for redOrbit.com - Your Universe Online Researchers have known for a long time that blind and visually impaired people rely on other senses. A new study led by the University of Southampton, however, now shows that they have the potential to use echolocation, similar to that of bats and dolphins, to determine the location of an object. The researchers examined how hearing, particularly the hearing of echoes, could help blind people with spatial awareness and navigation....


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
