The Human Journey: Migration Routes When humans first ventured out of Africa some 60,000 years ago, they left genetic footprints still visible today. By mapping the appearance and frequency of genetic markers in modern peoples, we create a picture of when and where ancient humans moved around the world. These great migrations eventually led the descendants of a small group of Africans to occupy even the farthest reaches of the Earth. Our species is an African one: Africa is where we first evolved, and where we have spent the majority of our time on Earth. The earliest fossils of recognizably modern Homo sapiens appear in the fossil record at Omo Kibish in Ethiopia, around 200,000 years ago. Although earlier fossils may be found over the coming years, this is our best understanding of when and approximately where we originated.
Solar Roads Could Power An Entire Country A small US-based company called Solar Roadways are developing a solar road surface that, if installed nationwide, has the potential to produce more renewable energy than the entire country uses. In fact, they’ve actually already developed a working prototype that’s been installed in a parking lot, and they’re now crowdsourcing funds in order to tweak the design and move towards production. Solar Roadways, which was started by Scott and Julie Brusaw in 2006, designed and developed hexagonal glass solar panels studded with LED lights that could be installed on a variety of surfaces such as roads, pavements and playgrounds. Kirlian Energy Fields Radiation Fields - Energy Fields - Reflected Zones The human energy field is thought to contain information that relates to all the activity going on within and around the person. The human aura or light body is invisible because our eyes only respond to a band of wavelengths called the visible spectrum and as the aura lies outside of this most people are unable to see it with the naked eye. However throughout history many seers and sensitive’s have claimed to see this aura surrounding people.

The Spice That Prevents Fluoride From Destroying Your Brain Fluoride is found everywhere today, from antibiotics to drinking water, no stick pans to toothpaste, making exposure inevitable. All the more reason why new research proving this common spice can prevent fluoride damage is so promising! Fluoride’s neurotoxicity has been the subject of academic debate for decades, and now a matter of increasingly impassioned controversy among the general public, as well. From ‘conspiracy theories’ about it being first used in drinking water in Russian and Nazi concentration camps to chemically lobotomize captives, to its now well-known IQ lowering properties, to its ability to enhance the calcification of the pineal gland – the traditional ‘seat of the soul’ – many around the world, and increasingly in the heavily fluoridated regions of the United States, are starting to organize at the local and statewide level to oust this ubiquitous toxicant from municipal drinking water. The study concluded, Discussion
New Physics Formula Links Quantum Mechanics And Pure Math The notorious number Pi has succeeded in becoming even more prevalent in science. Researchers from the University of Rochester discovered that a formula which approximates the energy levels of a hydrogen atom is the same as the one developed 360 years ago by English mathematician John Wallis to find the value of Pi. The pair of physicists realized that when the variational method was employed to calculate the energy levels of the hydrogen atoms, the formula could be simplified into the Wallis Product, the one used for Pi. The variational method is used to approximate the lower energy states of atoms, when the electrons are close to the nucleus. It is not usually used on the hydrogen atom, as hydrogen is simple enough so scientists can compute the energy levels precisely. Energy levels give an indication of how tightly bound the electron is to an atom; the larger the energy level, the easier it is for the electron to break free.
The Origin of Humans Is Surprisingly Complicated HUMAN FAMILY TREE used to be a scraggly thing. With relatively few fossils to work from, scientists' best guess was that they could all be assigned to just two lineages, one of which went extinct and the other of which ultimately gave rise to us. Discoveries made over the past few decades have revealed a far more luxuriant tree, however—one abounding with branches and twigs that eventually petered out. Data Storage in Crystal Quartz will change Everything! You know how much I LOVE talking about new technology, right? Well, this is one that is going to blow your mind, make an excellent case for the Crystal Movement, and also mop the floor with “limited data storage” forever! There’s a new kind of storage device which many tech companies have been diving into in secret for the past few years, which Hitachi recently came out with a technology they are developing which is essentially a sheet of Quartz Glass, which could potentially save data up to 300 Million Years! If you didn’t know anything about storage devices that we currently have, but anything from records, CD’s, USB sticks, magnetic tape, none of these can even lay a finger on this new, very impressive technology. "The prototype is made of a square of quartz two centimeters wide and two millimeters thick.
Scientists Create Solid Light On a late summer afternoon it can seem like sunlight has turned to honey, but could liquid—or even solid—light be more than a piece of poetry? Princeton University electrical engineers say not only is it possible, they’ve already made it happen. In Physical Review X, the researchers reveal that they have locked individual photons together so that they become like a solid object. This Breathtaking Video Reveals How Humanity Took Over The World The Black Death. The Second World War. The Industrial Revolution. Scientists Just Created Crystals That Make Breathing Underwater A Possibility Danish scientists are a step closer to significantly helping people who suffer from respiratory ailments, thanks to a revolutionary new absorption crystal. Working out of the University of Southern Denmark, the group has uncovered crystalline materials which are capable of pulling oxygen out of both air and water, a discovery which could eventually mark the end of the need to carry around cumbersome oxygen tanks. The revolutionary crystalline material can bind and store oxygen in high concentrations, then control its release time depending on what the user needs. This new discovery could even benefit deep sea divers, giving them superhero-like abilities to stay submerged for extended periods of time without an air tank.
