Denisova Cave and the Mystery of the mtDNA Phylogenetic Tree « Rokus Blog Nobody expected a great surprise. Genetic testing of the little finger of an early hominin child found in the Siberian Denisova Cave, Kostenki, in the middle of archeological remains pertaining to Upper Paleolithic culture, would almost for sure confirm DNA similar to ours. There was a slim change that the pinky belonged to a Neanderthal from the neighborhood that got lost, but everything pointed at a an unequivocal member of the advanced group of hominins responsible for introducing symbolic art all over the world, the so-called anatomically modern humans (AMH). The collection of personal adornments and artifacts suggestive of symbolic behavior from the Early Upper Paleolithic deposits of Denisova Cave, Altai, is one of the earliest and the most representative of the Upper Paleolithic assemblages from Northern and Central Asia. Humans spend more time gathering around the campfire to celebrate their victory on Nature, only to challenge evolution in an entirely new way. Dr.

Drift Seeds and Drift Fruits Imagine yourself floating helplessly on the open sea, thousands of miles from land, your destination at the mercy of the wind and currents. Perhaps eventually you may drift ashore on the coral sand beaches of a remote tropical island or distant continent. This is precisely what happens to countless thousands of tropical drift seeds and fruits, a remarkable flotilla of flowering plants that travel the oceans of the world. Seeds provide the vital genetic link and primary dispersal agent between successive generations of plants. The tropical islands of Indonesia, Polynesia and the Caribbean probably have the greatest variety of drift seeds. Charles Darwin & Ocean Dispersal Of Seeds Plant dispersal by ocean currents has fascinated many famous explorers, including Charles Darwin and Thor Heyerdahl. During his famous voyage around the world on the H.M.S. After he returned to England, Darwin conducted flotation experiments with cultivated plants. The Hawaiian Silver Sword Nickernuts The Coconut
Nanotechnology Basics Home > Introduction > Nanotechnology Basics Nanotechnology Basics Last Updated: Friday, 14-Jun-2013 09:28:04 PDT What is Nanotechnology? Answers differ depending on who you ask, and their background. Coined as "nano-technology" in a 1974 paper by Norio Taniguchi at the University of Tokyo, and encompassing a multitude of rapidly emerging technologies, based upon the scaling down of existing technologies to the next level of precision and miniaturization. Foresight Nanotech Institute Founder K. In the future, "nanotechnology" will likely include building machines and mechanisms with nanoscale dimensions, referred to these days as Molecular Nanotechnology (MNT). Click image for larger version. This image was written using Dip-Pen Nanolithography, and imaged using lateral force microscopy mode of an atomic force microscope. It uses a basic unit of measure called a "nanometer" (abbreviated nm). There are one billion nm's to a meter. One thousandth of that is a millimeter.
The Shirt As with all these designs, try to start with a relatively clean, crisp bill. It will make it much easier. All folds should be sharply creased. It helps to go over the fold with a fingernail on a flat, hard surface. Start by folding the bill precisely in half lengthwise. Fold the bill one quarter of the way in from each side lengthwise. Turn the bill over. Turn the bill over again. Fold a little less than one third of the bill lengthwise from the opposite end as shown. Now you will fold inward in the same direction, tucking the previous fold under the "collar" created in step 4. Gently unfold the previous two folds, keeping the creases. (This step is hard to describe, but it is actually fairly easy.) (This is a close-up of what the fold should look like when complete.) (This is what it should look like after both sides are complete.) When you re-tuck the fold you've been working on back under the collar, you're done!
Flowers in Ultra-Violet The compilation of species will continue to be updated at irregular intervals. All species listed here have been documented, and links are added whenever I can find spare time for updating. These images are made for illustrative purposes, not as artistic statements per se. However, there are lots of food for thought in the convoluted ways Nature expresses itself, so for once the artist can step backand let the subjects speak for themselves. "Das Ding an Sich" to paraphrase Kant, or Eigenvalue of Nature. If you are unfamiliar with the botany, just select any species indicated as having a "strong" response to learn how this looks. However, not all species have the typical bull's-eye UV pattern, which may be confined to symmetrical flowers. The UV range of the spectrum has no predefined colours, so we are free to assign any colour we like. UV fluorescence may be a common trait to most flowers, but might be of temporary occurrence for parts of the flower.
