Scarabaeus Satyrus
''Scarabaeus satyrus'' is one of the Old World dung beetle species. These beetles roll a ball of dung for some distance from where it was deposited, and bury it, excavating an underground chamber to house it. An egg is then laid in the ball, the growing larva feeding on the dung, pupating, and eventually emerging as an adult. Navigation In a study by Marie Dacke published in the journal ''Current Biology'', it is reported that researchers have found that beetles of this species use the bright glow from the Milky Way to navigate during night-time operations. Vertebrates such as humans, birds and seals are known to navigate in this way, but this could be the first insect found to do the same. Previous experiments showed that these beetles are able to steer by light from the Sun, the Moon, and polarised light emanating from these light sources. It was their ability to stay on course on clear moonless nights that puzzled researchers. Beetles were taken into the Johannesburg Planetar ...

Edward Julius Detmold05
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned.

Old World
The "Old World" is a term for Afro-Eurasia that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and they have a p ...

Marie Dacke
Marie Ann-Charlotte Dacke is a professor of Sensory Biology, at the ''Lund Vision Group'' in Lund University, Lund, Sweden. Her research focuses on nocturnal and diurnal compass systems, using the dung beetle as a model organism. Dacke is a Wallenberg Scholar as of 2025. In 2022 she was elected a fellow of the Royal Swedish Academy of Sciences. Dacke has a keen interest for the education of the general public and among other things act as a panel member of the Swedish TV show ''Studio Natur''. In 2013 she received an Ig Nobel Prize for her work on the navigation system of dung beetles. Since 2018, she is also an honorary professor at the University of the Witwatersrand in Johannesburg, South Africa. Early life and career Dacke went to high school in Landskrona. After graduating from high school she attended Lund University where she studied biology. Here, she completed her Ph.D. on ''Celestial Orientation in Dim Light'' in 2003, under the supervision of Professor Dan-Eric Nils ...

Milky Way
The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term ''Milky Way'' is a translation of the Latin ', from the Greek ('), meaning "milky circle". From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of , but only about 1,000 light years thick at the spiral arms (more at the bulg ...

Johannesburg Planetarium
The Johannesburg Planetarium seen from Yale Road The Johannesburg Planetarium is a planetarium owned by the University of the Witwatersrand, located on the University's East Campus in Braamfontein, Johannesburg. It was the first full-sized planetarium in Africa, and the second in the southern hemisphere. History The idea of setting up a planetarium in Johannesburg was first discussed in 1956 when the Festival Committee — which had been instituted to organise the celebrations of Johannesburg's seventieth anniversary — decided to raise the funds necessary to buy and house a Zeiss planetarium to be set up for the celebrations. As there was too little time to obtain a new instrument, it was decided to buy an existing planetarium projector from Europe. After lengthy negotiations, the Festival Committee was successful in persuading the Parliament of Hamburg to sell their planetarium's projector which had been in use there since 1930. The Hamburg Parliament, however, imposed as its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
