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.

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.

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.

Prehistoric Cave-art. Prehistoric Cave Art: Prehistoric cave-art is important as it serves as some of the best means of showing the interaction between our primitive ancestors and the world as they perceived it. The Image (right) is the most basic self portrait (From Pech Merle, c. 25,000 BP). Through it we can see the first steps of our awakenings as a species. There are certain characteristics of cave-art that allow us to begin to form an impression of the people behind the drawings, often found at the depths of long, deep tunnel systems in small secretive caverns.

Crystals Properties: Although not a crystal, abalone shell has been used for centuries in jewelry and carvings. Nicknamed the sea ears, the Abalone's flattened, oval shape with iridescent interior was used by the Native Northwest American Indians as a natural vessel for cleansing, offerings and prayers. Embracing the colors of the ocean, the shell displays iridescent colors in its blues, greens, purples and yellows. Feng Shui: Use in the Center area for grounding, balance, good health, spirituality and a sense of peace. History: Abalone are actually small to very large edible sea snails. Agate: Properties: Composed of microscopic crystals of Quartz laid down in colorful bands or ribbons. Folk Remedies: Agate is a fertility stone used for centuries. Feng Shui: Agate is used primarily anywhere to help bring change. Crystal Cleansing: method 1 - 2 and method 5 - 8 History: Agate is (SiO2) quartz with the addition of Al, Ca, Fe, Mn.

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.

The Science Gap - Watch Jorge's TEDx Talk: Discovery of oldest human DNA in Spanish cave sheds light on evolution | Science Researchers have read strands of ancient DNA teased from the thigh bone of an early human who died 400,000 years ago in what is now northern Spain. The genetic material was pieced together from a clutch of cells found in bone fragments – the oldest human remains ever to yield their genetic code. The work deepens understanding of the genetics of human evolution by about 200,000 years, raising hopes that researchers can build a clearer picture of the earliest branches of the human family tree by studying the genetic make-up of fossilised remains dug up elsewhere. "This is proof of principle that it can be done," said Matthias Meyer at the Max Planck Institute for Evolutionary Anthropology in Leipzig. The thigh bone was among the remains of at least 28 early human ancestors found at the bottom of a vertical shaft in a cave complex in the Atapuerca mountains in northern Spain. The age of the bone fragments meant the cells and their DNA were badly degraded.

Minerals and Gems More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple molecules or individual elements arranged in repeating chains, sheets, or three-dimensional arrays. Minerals are typically formed when molten rock, or magma, cools, or by separating out of mineral-rich water, such as that in underground caverns. In general, mineral particles are small, having formed within confined areas such as lava flows or between grains of sediments. Rocks themselves are made of clusters or mixtures of minerals, and minerals and rocks affect landform development and form natural resources such as gold, tin, iron, marble, and granite. Silicates—including quartz, mica, olivine, and precious minerals such as emeralds—are the most common class of minerals, as well as the major components of most rocks. Gemstones
