Scientists Discover The Oldest, Largest Body Of Water In Existence--In Space Scientists have found the biggest and oldest reservoir of water ever--so large and so old, it’s almost impossible to describe. The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush. Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water--20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth--Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over--20,000 times over. The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together. The new cloud of water is enough to supply 28 galaxies with water.
L'Homme qui prenait sa femme pour un chapeau Un article de Wikipédia, l'encyclopédie libre. L'Homme qui prenait sa femme pour un chapeau (titre original : The Man Who Mistook His Wife for a Hat) est un livre publié en 1985 par Oliver Sacks, neurologue d'origine anglaise. Il s'agit plus précisément d'un recueil dans lequel l'auteur décrit les affections « les plus bizarres » qu'il a rencontrées. Le titre provient du cas d'un homme qui savait reconnaître les objets composés de formes géométriques simples, tel un chapeau, mais pas les visages, dont le sien et celui de sa femme. Résumé[modifier | modifier le code] Ce livre n'est pas un livre de médecine qui nécessite des connaissances en neurologie pour être apprécié. Parmi les essais, citons ceux portant sur : Jimmie G. a perdu la capacité de former sa mémoire à court terme à cause du syndrome de Korsakoff.

Feinmann: "Levantaron el programa porque son unos inútiles" En medio de la polémica por la nueva amenaza del Gobierno al grupo Clarín, el periodista Eduardo Feinmann aseguró ayer que las autoridades de C5N, propiedad del empresario kirchnerista Cristóbal López, decidieron levantar Sala de situación , su habitual programa de los lunes en esa señal, para poner un documental sobre "Los enigmas del cerebro". Ayer por la tarde, el periodista condujo el ciclo El diario , que se emite por esa señal, contó los motivos de la suspensión del programa y apuntó contra los gerentes de noticias, Marcelo Salomone y Patricio Malagrino. "No me voy a callar. No lo levantaron por [Guillermo, secretario de Comercio Interior] Moreno ni por la despachante de aduana. Lo levantaron porque son unos desprolijos y unos inútiles", señaló Feinmann, al tiempo que aclaró que Cristóbal López no estuvo involucrado en la decisión. La gerencia de C5N aseguró que el levantamiento del programa Sala de Situación "se debió a estrictas razones artísticas y de programación" del canal.
Here are 10,000 reasons to be excited about deep-space exploration They'll ask why we continue to strive to see further and deeper into space than ever before, without knowing what we'll find. They'll ask why we insist upon exploring a solar system that, by their account, has no immediate bearing on our lives. And they'll ask why, in light of recent budgetary crises, space agencies the world over deserve funding to seek out answers to the mysteries of a Universe that we will never fully understand. Strawmen are made of straw. The first two questions are asked by ignoramuses. To use an analogy, I love travel. But even if we all can agree on the value of travel, is it still not grossly irresponsible to pay for your vacation to Europe or your study-abroad in India when you can't pay your rent, utilities or student loans without a credit card? I loved Hubble, and I'm sure I'll equally love the Webb telescope. But let's not kid ourselves by pretending that we are not in a place today that forces us to make budgetary priorities.
Scientists select new species for top 10 list; issue SOS The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists - scientists responsible for species exploration and classification - today announce the top 10 new species described in 2009. On the list are a minnow with fangs, golden orb spider and carnivorous sponge. The top 10 new species also include a deep-sea worm that when threatened releases green luminescent "bombs," a sea slug that eats insects, a flat-faced frogfish with an unusual psychedelic pattern, and a two-inch mushroom that was the subject of a "Bluff the Listener" segment on the National Public Radio quiz show "Wait, Wait Don't Tell Me." Rounding out the top 10 list are a banded knifefish, a charismatic plant that produces insect-trapping pitchers the size of an American football, and an edible yam that uncharacteristically sports multiple lobes instead of just one. Issuing an SOS The winners are ... It's about diversity Commemorating May 23 birth of Linnaeus
(+99) SeaOrbiter, el buque vertical de investigación será constr ¿Buque? ¿Barco? ¿Submarino? No es ninguno en particular, pero es todos a la vez. Eso es el SeaOrbiter, una especie de combinación entre un barco vertical y un submarino. Durante 12 años, el SeaOrbiter ha sido un vehículo conceptual, pero ahora, en pleno 2012, parece que la tecnología podrá traerlo a la vida. En cualquier caso, la función que ejercerá el buque es la de un centro de investigación de la vida marina y por supuesto de los océanos. El SeaOrbiter entero ha sido diseñado para usar energía solar, energía eólica y energía mareomotriz, aunque también contará con algunos depósitos de biocombustible a bordo. Por cierto, la construcción del barco comenzará en octubre y costará $43 millones de dólares.
Motion Mountain - The Free Physics Textbook for Download Sleep is More Important than Food - Tony Schwartz by Tony Schwartz | 10:37 AM March 3, 2011 Let’s cut to the chase. Say you decide to go on a fast, and so you effectively starve yourself for a week. At the end of seven days, how would you be feeling? You’d probably be hungry, perhaps a little weak, and almost certainly somewhat thinner. Now let’s say you deprive yourself of sleep for a week. Here’s what former Israeli Prime Minister Menachem Begin had to say in his memoir White Nights about the experience of being deprived of sleep in a KGB prison: “In the head of the interrogated prisoner a haze begins to form. So why is sleep one of the first things we’re willing to sacrifice as the demands in our lives keep rising? Many of the effects we suffer are invisible. So how much sleep do you need? When I ask people in my talks how many had fewer than 7 hours of sleep several nights during the past week, the vast majority raise their hands. Great performers are an exception. Go to bed earlier — and at a set time.

Sin embargo, algunas búsquedas que son más específicas Google no tiene la capacidad prefiere no enfocarse en eso y deja el trabajo a otros buscadores que son geniales para hacerlo. A continuación te dejo : 1 Existen ya muchos sitios para buscar empleo y bolsas de trabajo en internet que puede hacer cansada la búsqueda independiente en cada uno de ellos. 2 Un problema sobre los servicios para compartir archivos como mediafire y megaupload es que no tienen un buscador que te ayude a encontrar el archivo que necesitas… Pues este problema terminó. 3 Un buscador de personas muy interesante que seguro si le dedicas un tiempo te encuentras por todos lados. 4 Twitter es la red con más información en tiempo real y para muchos es la mejor fuente de información (mejor que los medios tradicionales). 5 Dentro de los servicios para compartir video tenemos a Youtube, pero no es el único. buscadores alternativos

Interested in learning more about any of these events? 13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it’s a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design. Photo by Cristian Bortes Aidan Dwyer took a hike through the trees last winter and took notice of patterns in the mangle of branches. To see why they branch this way he built a small solar array using the Fibonacci formula, stepping cells at specific intervals and heights. His results did turn out to be incorrect though.
