Bats And Whales Share Echolocation Success Story
2013-10-30 04:37:49

[ Watch the Video: Echolocation Frequencies Similar In Bats And Whales ] April Flowers for redOrbit.com - Your Universe Online What could a 50 ton whale and a one gram bat have in common? They share a success story - both have developed the ability to use echolocation, a type of biological sonar, for hunting. A new study from Aarhus University and the University of Southern Denmark reveals that the biosonar of toothed whales and bats share surprisingly many similarities - even though...

New Electric Fish
2013-09-25 12:54:23

Lee Rannals for redOrbit.com - Your Universe Online A new species of electric fish has been discovered in the murky waters of the upper Mazaruni River in South America. Scientists reported in the journal Zoological Scripta that they discovered a species that they've dubbed Akawaio penak in the remote regions in northern Guyana during an expedition. The team analyzed tissue samples collected during the trip, and found that the fish represents not only a new species but also a new genus....

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...

The larger the moth, the better hearing senses it needs if it wants to avoid its worst enemy, the bat. A large moth is easier to detect for a bat, and therefore evolution has forced large moths to develop larger and more sensitive ears. But the improved hearing comes at a price, says sound researcher Annemarie Surlykke from University of Southern Denmark. Bats orient themselves through echolocation, and they find their prey by emitting calls and then process the echoes reflected back to...

Chirp Of A Rare Bushcricket Is As Loud As A Power Saw
2013-07-23 14:56:24

AlphaGalileo Foundation A recently rediscovered species of bushcricket uses elastic energy and wing movement to reach high ultrasonic frequencies involving sound levels of about 110dB -- comparable to that of a power saw. The reason for a bushcricket species' unusually loud and ultra-high frequency calling song has been detailed in a new paper. Ben Chivers, who is studying animal behavior at the University of Lincoln, UK, co-authored the paper which illustrates the process in which...

Moths Jam Bat Echolocation Systems
2013-07-05 09:04:09

Brett Smith for redOrbit.com - Your Universe Online For years, the military has used radio signals to jam an enemy's radar and a new study in the journal Biology Letters suggests hawk moths use the same technique to evade predation by bats. According to the study's authors from the University of Florida, hawk moths emit sonic pulses from their genitals in response to the high-frequency echolocation that bats produce to locate prey. "This is just the first step toward understanding a...

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...

Weakly electric fish spend their lives bathed in their own internally generated mild electric field, interpreting perturbations in the field as objects pass through and when communicating with members of their own species through high frequency electric 'chirps'. Rüdiger Krahe, from McGill University, Canada, says, 'These fish are very cryptic and hard for us to understand because we don't have this electric sense'. Electric fish actively produce their weak electric fields;...

High-Pitched Echolocation Helps Harbor Porpoises Avoid Killer Whales
2013-06-12 14:17:20

Lee Rannals for redOrbit.com — Your Universe Online Researchers from the University of Southern Denmark (SDU) have determined why harbour porpoises are doing so well in coastal and busy waters. The team wrote in the journal Frontiers in Physiology that these animals are able to thrive through the Northern Hemisphere due to their sophisticated echolocation abilities. Coastal waters like the ones harbor porpoises live in can be challenging for whales due to the risk of beaching and...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
