  After the second World War, in the Soviet Union, a lot of music was banned, especially from the US and UK, but Russian as well. People still wanted to hear those songs though, so bootleggers figured out a way to use the various recording machines that were brought back from Germany as trophies.  They couldn't get their hands on vinyl, so they turned to used x-ray plates. And it came to be known as Bone Music. Here  they have an old recording of Bill Haley & His Comets, as well as some others if you click around. ***** In prehistoric times, tribes used bones to make music as well.  The Aztecs used an instrument called omichicahuaztli , in some cases carved from humerus bones, but often femurs. These would be scraped by smaller bones to produce sounds, a form of idiophone.

 Do you....believe? UFO researcher Jaime Maussan sure does, but others are more skeptical. A forensic doctor with the Mexican navy claims, after X-ray and CT scans, that it is a complete organic being - with eggs inside. But a NASA scientist is asking why the data is not being made available for examination by the public. It should also be noted that Maussan presented an "alien" in 2015 as well, which turned out to be the remains of a human child who had undergone cranial deformation.  In 2018, he found what was determined to be a dog mummy, though the head had been carved with the snout and teeth removed. From an anthropological standpoint, that's worth wondering about. Especially because another article reveals that early humans would return to burial caves to manipulate human remains.  They found evidence of a skull cup in southern Spain, as well as other bones modified into tools. "Such cultural elements may vary, but the proximity of and interaction with the phy...

  This is Mia, a bearded vulture who was found without a foot. They're the largest flying bird, and as scavengers, landing is an important process which needs two good feet to maneuver successfully. So the Department of Plastic, Reconstructive, and Aesthetic Surgery MedUni in Vienna, Austria worked to create a prosthetic using osseointegration. Called a "Plug and Play" limb, the prosthesis is connected directly to the bone, and has been used to replace a human hand as well. "Osseoperception provides direct intuitive feedback, thereby allowing natural use of the extremity for walking and feeding," says Dr. Oskar Aszmann of MedUni.  The surgery was a success.  Mia attempted to walk after just three weeks, with full weight bearing at six weeks. "Today the bearded vulture can once again land and walk using both feet, making it the first 'bionic bird.'"  For bidirectional communication, a titanium plate is implanted in the bones and the nerves are w...

Scientists Sebastien Enault and Camille Auclair like to piece skeletons together, and they do an awesome job. "As trained scientists with a concern for precision and a keen eye for aesthetics, we focus on anatomical accuracy and take into consideration animal behavior and movement to produce visually stunning displays of vertebrate anatomy." Their most recent work is the cartilaginous skeleton of the shortfin mako shark. The duo claim preparation of these fishes is their specialty, and they have developed their own technique for preservation of these delicate structures. An undulate ray. Northern wobbegong shark. Blue shark. And a bony vertebrate: Mahi-Mahi Kraniata IFLScience

Art Class - Venus of the Paleolithic

Image
Carved from mammoth ivory in the Upper Paleolithic period, Venus of Brassempouy is considered the earliest known representation of a human face. It was found in Brassempouy, France in 1894, inside the Pope's Cave (Grotte du Pape).  It is believed to have been made with a burin, or cold chisel, from the Gravettian culture. The people from the Upper Paleolithic period made numerous Venus figurines of the body, such as Venus of Hohle Fels, which is the oldest piece found to date.  Also made from mammoth ivory, it was found in Hohle Fels cave in Germany.   Venus of Hohle Fels belongs to the Aurignacion culture, which preceded the Gravettian.  These people are associated with the earliest presence of Cro-Magnon in Europe.  Other pieces of art have been interpreted as early evidence of religion as well as the oldest instrument ever found - the bone flute.
