Forum Rules (Everyone Must Read!!!)

1] What you CAN NOT post.

You agree, through your use of this service, that you will not use this forum to post any material which is:
- abusive
- vulgar
- hateful
- harassing
- personal attacks
- obscene

You also may not:
- post images that are too large (max is 500*500px)
- post any copyrighted material unless the copyright is owned by you or cited properly.
- post in UPPER CASE, which is considered yelling
- post messages which insult the Armenians, Armenian culture, traditions, etc
- post racist or other intentionally insensitive material that insults or attacks another culture (including Turks)

The Ankap thread is excluded from the strict rules because that place is more relaxed and you can vent and engage in light insults and humor. Notice it's not a blank ticket, but just a place to vent. If you go into the Ankap thread, you enter at your own risk of being clowned on.
What you PROBABLY SHOULD NOT post...
Do not post information that you will regret putting out in public. This site comes up on Google, is cached, and all of that, so be aware of that as you post. Do not ask the staff to go through and delete things that you regret making available on the web for all to see because we will not do it. Think before you post!


2] Use descriptive subject lines & research your post. This means use the SEARCH.

This reduces the chances of double-posting and it also makes it easier for people to see what they do/don't want to read. Using the search function will identify existing threads on the topic so we do not have multiple threads on the same topic.

3] Keep the focus.

Each forum has a focus on a certain topic. Questions outside the scope of a certain forum will either be moved to the appropriate forum, closed, or simply be deleted. Please post your topic in the most appropriate forum. Users that keep doing this will be warned, then banned.

4] Behave as you would in a public location.

This forum is no different than a public place. Behave yourself and act like a decent human being (i.e. be respectful). If you're unable to do so, you're not welcome here and will be made to leave.

5] Respect the authority of moderators/admins.

Public discussions of moderator/admin actions are not allowed on the forum. It is also prohibited to protest moderator actions in titles, avatars, and signatures. If you don't like something that a moderator did, PM or email the moderator and try your best to resolve the problem or difference in private.

6] Promotion of sites or products is not permitted.

Advertisements are not allowed in this venue. No blatant advertising or solicitations of or for business is prohibited.
This includes, but not limited to, personal resumes and links to products or
services with which the poster is affiliated, whether or not a fee is charged
for the product or service. Spamming, in which a user posts the same message repeatedly, is also prohibited.

7] We retain the right to remove any posts and/or Members for any reason, without prior notice.


- PLEASE READ -

Members are welcome to read posts and though we encourage your active participation in the forum, it is not required. If you do participate by posting, however, we expect that on the whole you contribute something to the forum. This means that the bulk of your posts should not be in "fun" threads (e.g. Ankap, Keep & Kill, This or That, etc.). Further, while occasionally it is appropriate to simply voice your agreement or approval, not all of your posts should be of this variety: "LOL Member213!" "I agree."
If it is evident that a member is simply posting for the sake of posting, they will be removed.


8] These Rules & Guidelines may be amended at any time. (last update September 17, 2009)

If you believe an individual is repeatedly breaking the rules, please report to admin/moderator.

  • Bats Recognize Individual Voices

    Bats hunt in groups in the dark using a form of sonar called echolocation to find snatch bugs out of the air.


    Scientists have not known how bats recognize their buddies, in order to stay together, and also avoid creating interference between their echolocation calls. The screech of a bat is louder than a rock concert. A study last year found that bats actually shut their traps for microseconds so they can hear the leader and take direction.


    Now researchers say greater mouse-eared bats can recognize individual bat voices.


    The researchers first tested the ability of four greater mouse-eared bats to distinguish between the echolocation calls of other bats. After observing that the bats learned to discriminate the voices of other bats, the scientists programmed a computer model that reproduces the recognition behaviour of the bats. Analysis of the model suggests that the signals contain information specific to each individual.

      I saw that article too: http://www.livescience.com/animals/0...at-voices.html

      Live Science is a great resource.
      I was taught how to think.

        Why is it that these science articles are dumbed down? Why aren't terms like frequencies used instead of voice?

        "The screech of a bat is louder than a rock concert."

        How about some comparison in decibel levels?

        This article is crap.....

          It's not the article... They're writing for the layperson and the reporters aren't so great anyways. If it sounds interesting, look up the actual article based on the information (researchers names, journal it's being published in, etc).

            Here, I found it. It's the peer-reviewed publication by the researchers.

              I know Siggie, but this crap they publish in the media is where people get their knowledge.... somebody who isn't knowledgeable in the subject matter shouldn't be reporting about it.

              "Scientists have not known how bats recognize their buddies"? lol

              or

                Or the education system as a whole can benefit from improving science literacy.

                  KanadaHye. I think this article has been edited by PepsiAddict, that's why.

                    Bats are amazing in the way on how they skillfully fly so fast maintaining such tight formations while pulling breakneck G manuevers............all the time not missing a beat on socializing with their wingman, using strictly Radar!
