WTF Is This Weird Web-Tower Thing? We Asked Around. No One Knows | Science So far, no one knows what’s crafting these enigmatic structures. Update, 1 p.m.: We’ve added comments from several more experts, below. Something in the Peruvian Amazon is making weird, intricate structures that resemble white picket fences surrounding an Isengard-like spire. No one has any idea who the mysterious craftsbug (fungus? spider?) The first of the fence-and-spire structures, spotted June 7. Troy Alexander, a graduate student at Georgia Tech, spotted the first of these structures on June 7. “All of them were on the small island used to view the parrot clay lick at Tambopata Research Center,” Alexander said. We noticed the weirdness last Thursday, when Phil Torres, a biologist who also works at Tambopata, posted a link on Twitter. But it turns out that even scientists who study such things haven’t a clue. “I have no idea what made it, or even what it is,” said William Eberhard, an entomologist with the Smithsonian Tropical Research Institute. *Here are a few more:
REACCIONES QUÍMICAS INORGANICAS Es la parte de la química que se ocupa del cálculo de las cantidades de sustancia que intervienen en una reacción química. Definición Proceso en el que cambia la naturaleza de una o varias sustancias (reactivos), transformándose en otras nuevas(productos). Esto supone un reordenamiento de los átomos, mediante la ruptura de unos enlaces y la formación de otrosnuevos.Una reacción química se representa mediante una ecuación química: En el primer miembro aparecen las fórmulas de lassustancias que reaccionan (reactivos), y en el segundo miembro aparecen las fórmulas de las sustancias que se forman(productos), separados por una flecha, si la reacción es irreversible o por dos (una para cada sentido), si la reacción esreversible. Además de las fórmulas de las sustancias, deben aparecer los denominados coeficientes estequiométricos, loscuales nos indican la proporción (moles) de las sustancias que intervienen en la reacción (ajuste). a) 2Na + Cl 2NaCl (irreversible)b) H O (reversible)c) 2H (g) + O

Wonderful Portraits Of Different Owl Species By Brad Wilson Photographer Brad Wilson captures incredible portraits of different owl species from the World Bird Sanctuary in St. Louis and The Wildlife Center near Española, New Mexico… Great Horned Owl Barn Owl Western Screech-Owl Eastern Screech-Owl Spectacled Owl Eurasian Eagle-Owl Mexican Spotted Owl Flammulated Owl Long-Eared Owl Photos © Brad Wilson | via mymodernmet | Audubon Tipos de Reacciones y Ecuaciones Químicas Las reacciones químicas, son proceso, en los que, algunas sustancias, se recombinan con otras, para formar, sustancias nuevas; es decir, diferentes a las que tenía al principio. Estas reacciones, se representan, a través de las ecuaciones químicas. Veamos un ejemplo, para explicarlo: se tiene el hidrógeno molecular, más, el oxígeno molecular, que reaccionan, para formar agua. En estas ecuaciones, del lado izquierdo, se anotan los reactivos, que son las sustancias que se recombinan, y del lado derecho, los productos, que son las sustancias nuevas (H2+O----˃ H2O). En química, el “+” significa “reacciona”, y la flecha, significa “produce”. Los principales tipos, de reacciones químicas son: *Reactivos de adición: Aquellos que tienen, dos o más reactivos, que se combinan para formar un producto, generalmente más complejo, que los reactivos anteriores. *Óxido-reducción: Los elementos, cambian su número de oxidación, y de esa forma, pierden o ganan electrones.
An Atlas of Cyberspaces This is an atlas of maps and graphic representations of the geographies of the new electronic territories of the Internet, the World-Wide Web and other emerging Cyberspaces. These maps of Cyberspaces - cybermaps - help us visualise and comprehend the new digital landscapes beyond our computer screen, in the wires of the global communications networks and vast online information resources. The cybermaps, like maps of the real-world, help us navigate the new information landscapes, as well being objects of aesthetic interest. They have been created by 'cyber-explorers' of many different disciplines, and from all corners of the world. Some of the maps you will see in the Atlas of Cyberspaces will appear familiar, using the cartographic conventions of real-world maps, however, many of the maps are much more abstract representations of electronic spaces, using new metrics and grids.

AMKK（東 信、花樹研究所） » HOUSE VISION 2013 TOKYO EXHIBITION：TOTO・YKK AP AMKK（東 信、花樹研究所） HOUSE VISION 2013 TOKYO EXHIBITION TOTO・YKK AP × 成瀬友梨・猪熊純「極上の間」 DATE：2013年3月２日(土)～24日(日) TIME : 11:00～20:00 (最終入場受付19:30） PLACE：臨海副都心J区（東京都江東区青海2丁目1） masaru emoto In all of these experiments, distilled water for hospital usage produced by the same company was used. Since it is distilled twice, it can be said that it is pure water. The result was that we always observed beautiful crystals after giving good words, playing good music, and showing, playing, or offering pure prayer to water. On the other hand, we observed disfigured crystals in the opposite situation. Moreover, we never observed identical crystals. I published these results as photograph collections: “Messages from Water 1” (1999), “Messages from Water 2” (2002), “Messages from Water 3” (2004), and “Messages from Water 4” (2008). This world is filled with wonders and mysteries that get more incomprehensible if we try to think of a reason. Thus, except for some of truly basic things, no one disagrees that there are still so many unknowns. Combination of non-resonating vibration can result in destructive energy, and nothing can be created out of it.
Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life.
