AI Thread Summary
Echolocation is a biological sonar used by certain animals, such as bats and some insects, to navigate and locate prey in their environment. It involves emitting sound waves and interpreting the echoes that bounce back, allowing these creatures to determine distance, direction, and even azimuth. Bats are particularly adept at using echolocation to hunt in darkness, while some insects, like crickets, utilize sound for mating purposes. The discussion also touches on human directional hearing, which, while not echolocation, demonstrates the ability to locate sounds based on their direction. Overall, echolocation is a complex process that extends beyond mere distance measurement to include spatial awareness and orientation.

Is there a specific question? Otherwise a google search would be more useful.
 


Or to narrow it down quickly, try www.wikipedia.org

.
 


You can do both. A google search on en.wikipedia.org

There is more to echolocation than just determining distance. There is also horizontal direction and azimuth. Bats can accurately locate prey in the dark. Some insects can accurately locate prey (or mates) by determining direction of sound. Female crickets chirp so male crickets can find them using a clever directional hearing system.

So can humans. Close your eyes and have someone pick someplace in the room to stand after your eyes are close and talk to you; you'll be able to find them based on direction of sound. Of course that's not echolocation, but just directional hearing.

The term echolocation is pretty self-explanatory in terms of a definition, though.
 

Thread 'New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours'

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
