    Scientists: Astronauts Could Build Moon Base Using Human Urine Need a resilient lunar building material? Urine luck. VICTOR TANGERMANN5 HOURS AGO In cooperation with the European Space Agency (ESA), a team of European researchers have conducted a… strange experiment. They mixed urea — the main compound found in mammalian urine — with materials, including Moon rocks, to test if we could one day use astronaut pee to build a lunar base. The urea itself acted as a “plasticizer” — stuff that allows us to shape other harder materials into different forms. In their unusual experiment, the team used an analog...

    The team used a 3D sand–hydrogel scaffold that they inoculated with Synechococcus sp. PCC 7002 (Synechococcus) — a photosynthetic cyanobacterium that converts CO2 to sugars during photosynthesis. Cyanobacteria are well known to survive extreme environmental conditions, including high and low temperature, salinity, and humidity, making them ideal candidates for living materials. These new materials are also capable of being regenerated from one parent “brick” using temperature and humidity switches. This corresponds to cycles of incubation at 37 °C, followed by low-temperature storage, where the gelatin matrix solidifies and encapsulates the bacteria. Splitting one brick in half and extending its shape...

    This video continues our study of ancient construction techniques. It presents the argument that the base casing stones of the most familiar pyramids may have been molded by some technology which used geopolymers (stone slurry?) This is similar to the speculation that the Incan stone walls were constructed using a similar process.

    A video on a hypothesis that the Inca stone walls in Peru were actually constructed by using a stone slurry packed into containers and hardened by fire/ This is a follow up to the previous thread about technology needed to cut precision stonework for the Egyptian pyramids and monuments. It hypothesizes a new theory of building neolithic stoneworks with techniques that are still used today, albeit in much smaller adobe structures.

    Over a month ago his left lung collapsed completely, and about a week ago his kidneys failed. His heart rate is now slowing down as well. Dad made it very clear to us from the beginning, upon receiving his diagnosis, that he did not want to live a life on life support. Although it's truly impossible to know for sure what recovery could look like, it is very clear that he would not have the quality of life he would want, nor the quality of life we would want for him. It was because of the virtually limitless support and...
  • Giza Pyramid mystery chamber may hold Pharaoh’s 'meteorite throne'

    A huge void discovered inside the Great Pyramid of Giza in Egypt late last year may hold an iron throne carved from meteorites, according to new analysis of ancient religious texts. Giulio Magli, Director of the Department of Mathematics and Professor of Archaeoastronomy at the Politecnico di Milano, studied the Pyramid Texts, religious writings carved into pyramid walls around 2400 BC. Based on his studies, Magli proposes that it’s possible the throne of Pharaoh Khufu – or ‘Cheops’ – lies inside the chamber. ================================================================================================================================ “Of course it would not be melted iron but meteoritic iron, that is, fallen from the...

    The device enters rooms and chambers through a 3.5 centimetre hole drilled through a wall by researchers outside. It is made up of two robots, a tubular machine equipped with a high definition camera and a probe that explores the structure via a small, inflatable blimp. After the first robot has taken a series of reconnaissance images, the drone is pushed through the drilled hole before inflating itself within the chamber. Packed with an array of sensors and cameras, the remote-controlled device collects data and takes photos or video without causing damage to the fragile building. After it has completed...

    Zahi Hawass, who heads the ScanPyramids science committee overseeing the project, said there was no new "discovery". He said he had met other scientists from ScanPyramids who "showed us their conclusions, and we informed them this is not a discovery," he told AFP. "The pyramid is full of voids and that does not mean there is a secret chamber or a new discovery," he said. In a statement on Friday, the head of the government's antiquities council Mustafa Waziri also criticised the announcement. "The project has to proceed in a scientific way that follows the steps of scientific research and...

    Starting November, the pyramids of Giza will be subject to a non-invasive survey in an attempt to unravel their secrets four millennia after their construction. “Several theories have been brought forward during the past century to understand the method that the ancient Egyptians used to construct the pyramids but all are still scientific hypotheses,” Minister of Antiquities Mamdouh Eldamaty told Ahram Online. Eldamaty continued, saying that the ScanPyramids project is a new means to learn how the pyramids were built and understand the reason behind the pyramid-shaped design. The scans will also detect the existence of any hidden chambers, corridors,...

    Archaeologists have uncovered a mysterious enclosure hidden deep inside the Great Pyramid of Giza, the oldest of the seven wonders of the ancient world. The massive cavity stretches for at least 30 metres and lies above the grand gallery, an impressive ascending corridor that connects the Queen’s chamber to the King’s in the heart of the historic monument. It is the first major structure found in the pyramid since the 19th century. It is unclear whether the void is a chamber or a corridor, or whether it played any more than a structural role in the pyramid’s construction – such...

    The ancient Egyptians who built the pyramids may have been able to move massive stone blocks across the desert by wetting the sand in front of a contraption built to pull the heavy objects, according to a new study. Physicists at the University of Amsterdam investigated the forces needed to pull weighty objects on a giant sled over desert sand, and discovered that dampening the sand in front of the primitive device reduces friction on the sled, making it easier to operate. The findings help answer one of the most enduring historical mysteries: how the Egyptians were able to accomplish...

    After decades of research, American archaeologist Mark Lehner has some answers about the mysteries of the Egyptian colossus When Mark Lehner was a teenager in the late 1960s, his parents introduced him to the writings of the famed clairvoyant Edgar Cayce. During one of his trances, Cayce, who died in 1945, saw that refugees from the lost city of Atlantis buried their secrets in a hall of records under the Sphinx and that the hall would be discovered before the end of the 20th century. In 1971, Lehner, a bored sophomore at the University of North Dakota, wasnÂ’t planning to...
  • This 4,500-Year-Old Ramp Contraption May Have Been Used to Build Egypt's Great Pyramid

    Archaeologists have long wondered exactly how the ancient Egyptians constructed the world's biggest pyramid, the Great Pyramid. Now, they may have discovered the system used to haul massive stone blocks into place some 4,500 years ago. They discovered the remains of this system at the site of Hatnub, an ancient quarry in the Eastern Desert of Egypt. The contraption would have been used to transport heavy alabaster stones up a steep ramp, according to the archaeologists working at the site, from the Institut français d'archéologie orientale (French Institute for Oriental Archaeology)in Cairo and from the University of Liverpool in England....

His research into volcanic ash that formed sedimentary rocks in Italy and California helps scientists better understand the ways ancient societies, including the Romans, used rocks to create mortar and concrete that, in some cases, was actually more durable than the modern varieties. Over hundreds of years, Romans experimented with different volcanic ash layers to perfect the building materials which would...

    U-M researchers make bendable concrete click image to see video ANN ARBOR, Mich.&#8212;A new type of fiber-reinforced bendable concrete will be used for the first time in Michigan this summer&#8212;and University of Michigan scientists hope that their new material will find widespread use across the country. The new concrete looks like regular concrete, but is 500 times more resistant to cracking and 40 percent lighter in weight. Tiny fibers that comprise about 2 percent of the mixture's volume partly account for its performance. Also, the materials in the concrete itself are designed for maximum flexibility. Because of its long...

    Where can you go to see a cool example of nanotechnology? Well, just about everywhere. A new study reveals that plain old concrete, the most common human-made material on the planet, owes its properties to its nanoscale structure. Down the road, this new understanding could lead to novel forms of concrete that require less energy and CO2 to generate and might allow researchers to engineer its properties much as they have done with advanced steel alloys. Concrete isn't what comes to mind when most people think of nanomaterials. It's the oldest engineered construction material and was first used by the...

    Experimental concrete that patches up cracks by itself is to undergo outdoor testing. The concrete contains limestone-producing bacteria, which are activated by corrosive rainwater working its way into the structure. The new material could potentially increase the service life of the concrete - with considerable cost savings as a result. The work is taking place at Delft Technical University, the Netherlands. It is the brainchild of microbiologist Henk Jonkers and concrete technologist Eric Schlangen. If all goes well, Dr Jonkers says they could start the process of commercialising the system in 2-3 years.
