Bumblebee waggle dance doubters disarmed
Stumble It!Bees really do point to new foodsources by dancing
The waggle dance is a famous example of the power of one-many broadcast communications in one of natures most successful teams – honeybees!
Physorg.com in an article, Bees equipped with radar solve waggle dance controversy, reports on a paper published in Nature on May 12th 2005 which provides new data that resolves a long-standing scientific controversy.
In the 1960s, Nobel Prize winning zoologist, Karl von Frisch, proposed that honeybees use dance (the "waggle dance") as a coded message to guide other bees to new food sources.
However, some scientists did not accept von Frisch’s theory.
In the new research using harmonic radar, scientists have now tracked the flight of bees that had attended a "waggle dance" and found that they flew straight to the vicinity of the feeding site, as predicted by von Frisch.
The tracks allowed the scientists to determine how accurately bees translate the dance code into successful navigation, and showed that they correct for wind drift even when en route to destinations they have never visited before.
So those clever little honeybees have turned out to be even smarter than we thought!

The short message phenomenon challenged
We are bombarded with the idea its good to talk and its good to text. But is texting and other forms of mobile phone interaction a useful form of communication? Or is it even a form of communication at all or something totally different? In a mini-book "Heidegger, Habermas and the mobile phone" the author invokes some key thinkers of the twentieth century to offer an essential alternative to the new doctrine of 'm-communication': Martin Heidegger, who saw humanity as ‘the entity which talks’ and Jürgen Habermas, current-day advocate of authentic communication.
