we are all human

Thanks to another blog I've been working on , I was introduced to the art of Samira Said , the great Morrocan-Egyptian artist. Those of a sharp memory may remember Said from to her participance in the 1980 Eurovision songs contest , the only one in which an African state took place. Morocco joined the Eurovision family for the first (and so far only) time, and some believe that they were only brought in to replace Israel , who declined to participate that year.  Participation in the Eurovision is not determined by geography, but by memebership in the European Broadcasting Area , as defined by the International Telecommunication Union . A quick glance at the countries that have participated in the Eurovision, or considered to do so , clarifies the difference between geo-political borders and tele-political borders in one way, and clarifies the artificial nature of borders in general, in another, deeper way... As the song states - We are all human. 

We are not the only ones to look at the sky

Until recently, we knew that only Humans, Birds and Seals use the starry night for navigation.  A new research teaches that Dung Beatles also share this use of the starry night sky.  The Verge reported this discovery, and explained how it was reached -   "Researchers made this discovery after examining the different ways in which the beetles push their balls of dung. Under normal conditions, the insects store their dung balls in a secure location by moving it along a straight path. As the study notes, the beetles were able to replicate this behavior under moonlit nights and on dark nights when only the Milky Way was visible, but struggled to navigate under more overcast conditions. In planetarium tests, they performed equally well under a fully starlit sky and one showing only the Milky Way. When researchers strapped visors to their heads to block out the sky entirely, they were completely disoriented." Image of the night sky of the Milky Way , our Galax
