Cosmetics is as old as the history of human being. It has been present in human life since the times of the most ancient civilizations. Perfumery is one of the oldest branches of cosmetics. Valerian perfumes found from the Pharaohs’ pyramids, had maintained their aroma. Coriander, Mace oil, cardamom, cinnamon, and juniper were also the favorite materials used for perfumery in ancient Egyptian c...

UNLABELLED We present Serial SimCoal, a program that models population genetic data from multiple time points, as with ancient DNA data. An extension of SIMCOAL, it also allows simultaneous modeling of complex demographic histories, and migration between multiple populations. Further, we incorporate a statistical package to calculate relevant summary statistics, which, for the first time allows...

Also known as... ancient DNA. The New Shorter Oxford Dictionary offers the precise explanation of ‘ancient’ as ‘belonging or pertaining to the period before the fall of the Western Roman Empire in AD 476.’ DNA can be recovered from fossils much older than 1500 years, but the inevitable time-dependent decay of the DNA structure due to oxidation and hydrolysis makes retrieval increasingly difficu...

Recombinations are known to disrupt bifurcating tree structure of gene genealogies. Although recently occurred recombinations are easily detectable by using conventional methods, recombinations may have occurred at any time. We devised a new method for detecting ancient recombinations through phylogenetic network analysis, and detected five ancient recombinations in gibbon ABO blood group genes...

the concept of logos is seen figuratively before christianity in ancient greek philosophy and judaism (old testament and some works of filon of alexandria). in ancient greek philosophy, logos is counted as the first principle, at least up to the middle platonism period, and more importantly, until the platonism period; that is to say, as it will be pointed out, logos was the first principle wit...

In fact, this assumption is incorrect and, whilst the Ancient Greek astronomers made huge contributions to astronomy, their knowledge was built upon the solid foundations laid by other great cultures. The Mesopotamian [1] and Zoroastrian astronomers and astrologers, in the Fertile Crescent and the empty deserts of Persia, made many sophisticated observations and devised complex theories to desc...

Introduction: Our present knowledge of water on Mars is biased toward the ancient sulfate-and phyl-losilicate-bearing sedimentary record – the product of liquid water's larger role in concert with vigorous sedimentary processes [1]. But the unfamiliar chemistry and mineralogy uncovered by the Phoenix Lander reflect physical and chemical processes of a different climate – one that has resulted f...

Cities are so common today that we cannot imagine a world without them. In fact, more than half of the world’s population lives in cities, and that number is expected to increase to two-thirds in the next century. For most of our history, however, there were no cities. Understandably, scholars want to know why, how, and when urban life began. Was the emergence of the city just a matter of nucle...
