Saturday, May 24, 2008 In Time and the Technosphere, Jose Arguelles presents a groundbreaking study that distinguishes the natural time of the cosmos from the artificial mechanistic time under which we currently live. Arguelles defines the actual nature of time as the frequency of synchronization. Applying this Law of Time to an understanding of the entire system of life on Earth, he shows that in order to not destroy Earth's ability to sustain life, we must change our definition of time and adopt a natural harmonic calendar based on the 13-moon 28-day cycle. Until the creation of the Gregorian calendar and the 60-minute hour, most of humanity lived by the 28-day cycle of natural time. The adoption of artificial time has subjected us to a 12:60 time frequency that governs the entire global industrialized civilization-the technosphere. With the collapse of the Twin Towers on September 11, a fissure was created in this artificial technosphere, opening up the nosphere (Earth's mental envelope). End Excerpt.

Huge Underwater Pyramid Discovered Near Portugal – The Navy is Investigating Portuguese news reported the discovery of a very large under water pyramid first discovered by Diocleciano Silva between the islands of São Miguel and Terceira in the Azores of Portugal. According to claims, the structure is said to be perfectly squared and oriented by the cardinal points. Current estimates obtained using GPS digital technology put the height at 60 meters with a base of 8000 square meters. The Portuguese Hydrographic Institute of the Navy currently has the job of analyzing the data to determine whether or not the structure is man-made. “The pyramid is perfectly shaped and apparently oriented by the cardinal points,” Silva told Diário Insular, the local newspaper. The pyramid was found in an area of the mid-Atlantic that has been underwater for about 20,000 years. While the Portuguese Navy still hasn’t determined the origins, many might question why this hasn’t been first reported on sooner than late 2012. Right: The actual pyramid, as scanned with high-tech device
What Is a Wind Farm? | Wonderopolis What do you think of when you hear the word “farm”? Animals? Vegetables? Tractors? Wind farms are areas where many large wind turbines have been grouped together to “harvest” the power of the wind. A large wind farm can contain hundreds of wind turbines spread out over hundreds of miles. Did you realize that wind energy is actually another form of solar energy? Wind farms are built in areas known to be especially windy on a regular basis. If it’s easier, you can think of a wind turbine as the opposite of a fan. If you’re wondering why scientists looked to the wind as an energy source, there are plenty of good reasons. On the negative side, wind farms can cost a lot of money to set up. Over time, scientists believe new technologies, such as using batteries to store wind power for peak demand times, will make wind power even more popular.

Study confirms that Neanderthals and humans got it on The genetic similarities between certain human populations and Neanderthals are striking. Indeed, many researchers think the Europeans and Asians inherited between 1 and 4 percent of their DNA from Neanderthals, yet scientists have struggled to demonstrate with a high degree of certainty that these genetic similarities are the result of interbreeding between these two species. Now, a pair of European scientists say that they have confirmed the human-Neanderthal reproduction hypothesis using statistical modeling — and these results, the researchers add, should go a long way to change the way we think of other human-like species. In the past, genetic similarities between Neanderthals and humans have been associated with two possible scenarios. "A model that involves interbreeding is much more likely." "We did a bunch of math to compute the likelihood of two different scenarios," says Laurent Frantz, study co-author and evolutionary biologist at Wageningen University in the Netherlands.
Plate Tectonics - Crust, Lithosphere, Mantle Topics Plate Tectonics Crust Lithosphere Mantle Density Buoyancy Earth Science Description Explore how plates move on the surface of the earth. Sample Learning Goals Describe the differences between oceanic and continental crust, including their respective properties of density, composition, temperature and thickness.Predict how changes in composition and temperature change crust density and buoyancy.Draw a time series for different types of plate boundaries and their motions, indicating the related surface features.Deduce the type of plate boundary given images or descriptions of surface features.Explain which types of plate boundaries create crust, and which destroy crust Version 1.02 DNA Analysis of Paracas Elongated Skulls Released: Unknown To Any Human, Primate, or Animal Paracas is located in the Pisco Province in the Inca Region on the Southern coast of Peru. Home of the ground breaking discovery in 1928 by Julio Tello of a massive graveyard containing tombs filled with the remains of individuals with elongated skulls, now known as the famous Paracas Skulls. They are approximately 3000 years old, and initial DNA analysis of them has revealed that they may not have come from humans, but from a completely new species, according to Paracas Museum assistant director, researcher and author Brien Foerster. Here is the apparent quote from the geneticist who did the testing “Whatever the sample labeled 3A has came from – it had mtDNA with mutations unknown in any human, primate or animal known so far. It’s always been thought that the skulls were a result of cranial deformation, where the head is bound or flattened to achieve the shape. “As I have said, deformation can alter shape, but not the volume of bone material, and certainly not twice as much.

Her bad luck is science’s good fortune. The story of her discovery begins in 2007, when a team of Mexican divers led by Alberto Nava made a startling find: an immense submerged cavern they named Hoyo Negro, the “black hole.” At the bottom of the abyss their lights revealed a bed of prehistoric bones, including at least one nearly complete human skeleton. Nava reported the discovery to Mexico’s National Institute of Anthropology and History, which brought together an international team of archaeologists and other researchers to investigate the cave and its contents. Together these remnants may help explain an enduring mystery about the peopling of the Americas: If Native Americans are descendants of Asian trailblazers who migrated into the Americas toward the end of the last ice age, why don’t they look like their ancient ancestors?
