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.

Bottle Drip Irrigation | I prefer to have the bottle standing right-way-up as I think it looks nicer and it keeps debris out of the bottle thus keeping the holes from blocking. The materials: * 2 litre plastic soft-drink bottle or water bottle * Sharp small screwdriver, pointed hole-maker or drill This can be used in container gardening, raised bed gardens and open vegetable gardens. Using your pocket knife, make 2 small slits in the bottom of your bottle. Dig a hole next to your tomato plant. This will slowly deep-water your tomato plants and most other vegetable plants. You can learn more about this on another website. Only two very small holes are needed at the lowest place on the bottle. I prefer to leave the lids off. Place bamboo stakes next to each bottle. Here I am making another hole slightly higher up the bottle. However, if I remove the lid, water will come out this hole as well as the holes in the base. You can make larger holes, and partly fill the bottle with coarse-sand or soil to slow the flow.

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.
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

All RHS adult courses Penn study shows why sleep is needed to form memories PHILADELPHIA – If you ever argued with your mother when she told you to get some sleep after studying for an exam instead of pulling an all-nighter, you owe her an apology, because it turns out she's right. And now, scientists are beginning to understand why. In research published this week in Neuron, Marcos Frank, PhD, Assistant Professor of Neuroscience, at the University of Pennsylvania School of Medicine, postdoctoral researcher Sara Aton, PhD, and colleagues describe for the first time how cellular changes in the sleeping brain promote the formation of memories. "This is the first real direct insight into how the brain, on a cellular level, changes the strength of its connections during sleep," Frank says. The findings, says Frank, reveal that the brain during sleep is fundamentally different from the brain during wakefulness. "We find that the biochemical changes are simply not happening in the neurons of animals that are awake," Frank says. A molecular explanation is emerging.
