    The Tepe Telegrams ^ | 7/18/2018 | Gobekli Tepe Research Staff
    Archaeological survey methods have changed significantly over the last years. One innovation which has dramatically changed the way field archaeologists work are ground-based physical sensing techniques (for a short introduction into this technology and its application see, e.g. here [external link]). This technology provides us with images of possible archaeological features beneath the surface without even taking a shovel to hand. In 2003, a geophysical survey was undertaken at Göbekli Tepe with the help of GGH -- Solutions in Geoscience GmbH. In a first step, large parts of the tell were subjected to extensive magnetic prospection, and later selected areas...

    The severely elongated head of a preserved skeleton found in Peru's Atacama Desert in 2003 is so unusual that it initially prompted people to suggest that the diminutive body was that of an extraterrestrial. Since then, DNA testing confirmed that the remains — which measure about 6 inches (15 centimeters) long — belonged to a human fetus that researchers named Ata. But the scientists who conducted that investigation and published their findings in March have recently come under fire for their methods. ...Their investigation, which did not include any Chilean researchers, may have sidestepped protocols that typically monitor the ethics...

    New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.” “Octonions are to physics what the Sirens were to Ulysses,” Decades on, no particles beyond those of the Standard Model have been found. Meanwhile, the strange beauty of the octonions has continued to attract the occasional independent-minded researcher, including Furey, the Canadian grad student who visited Günaydin four years ago. Looking like an interplanetary traveler, with choppy silver bangs that taper to a point between piercing blue eyes, Furey scrawled esoteric symbols on a blackboard, trying to explain to Günaydin that...

    The European Southern Observatory (ESO) and ESA (European space agency) teamed up to produce a packed Asteroid Day webcast. There were interviews with ESA and ESO scientists. Updates from Europe’s asteroid hunters and some of the most recent asteroid science results, including the blockbuster news on Oumuamua, the first-ever interplanetary visitor. The programme also included an interview with ESA astronaut Luca Parmitano on the challenges of future human missions to asteroids, as well as a surprise segment that answered the age-old question: What really killed off the dinosaurs? More than 1M asteroids have the potential to impact Earth and through...
  • T. Rex couldn't stick out its tongue

    T. rex may have been a highly successful predator, but it would have been terrible at licking stamps, lollipops or popsicles, thanks to a tongue that was likely fixed to the bottom of its mouth. A new study calls into question artists’ renditions of T. rex and other dinosaurs that show them with their tongues protruding from gaping jaws — a pose that is commonly seen in modern lizards. But even though lizards are tops at tongue waving, dinosaurs probably couldn't stick out their tongues, researchers recently discovered. Soft tissue is rarely preserved in the fossil record, so scientists turned...

    Researchers have unearthed a new armored dinosaur in Utah, a new species of ankylosaur, known as Akainacephalus johnsoni. The catch? It lived on the lost continent known as Laramidia. A. johnsoni, a member of the ankylosaurid family, lived 76 million years ago in what is now southern Utah, but was once a land mass known as Laramidia, an island continent that split North America in two. Eventually, the sea shrank and the two parts combined to form what is now known as North America. ..." Measuring between 13 and 16 feet in length and 3.5 feet tall, Akainacephalus jonhnsoni is...
  • Mystery black sarcophagus opened in Egypt

    Two weeks ago, archaeologists in Egypt found a massive black granite sarcophagus in Alexandria, untouched for 2,000 years - and fleet-footed rumour quickly got to work. Could it contain the remains of ancient Greek leader Alexander the Great, or (less appealingly) a deadly curse? According to experts who have now unsealed it, it's a no to both. Instead, it revealed three skeletons and red-brown sewage water, which gave off an unbearable stench.Egypt's Ministry of Antiquities had appointed a committee of archaeologists to open the relic, which was unearthed at a construction site. According to Egyptian news outlet El-Watan, they initially...

    In the flow of this 3.8 billion-year-old river of life it is death, not life, that drives evolution. Death is that which sculpts the flow of life. In the marketplace of business it is failure, not success, that shapes, sculpts and hones that which survives. Whether it is an inability to survive in ever-changing physical conditions or an inability to convince enough people to purchase your goods or services at the price you require, demise of the entity controls and shapes what remains. Death and failure are the invisible hands that ensure these systems remain somewhat in balance. They put...
  • Using your body to control a drone is more effective than a joystick

    If you've ever been chastised for throwing your entire body around during gaming (because physically leaning into track corners definitely helps somehow), here's a bit of science-backed vindication. Researchers in Switzerland have discovered that using your torso to control a drone is far more effective than using a joystick. The team from EPFL monitored the body movements and muscular activity of 17 people, each with 19 markers placed all over their upper bodies. The participants then followed the actions of a virtual drone through simulated landscapes, via virtual reality goggles. By observing motion patterns, the scientists found that only four...

    On his first foreign trip since taking office nearly three months ago, NASA Administrator Jim Bridenstine traveled to Israel last week to meet with the country's prime minister and other officials. Bridenstine's two-day visit to Israel, not announced by the agency until after he arrived in the country, highlighted NASA's good relationship, but only modest cooperation, with Israel's space agency and industry. He separately met with his direct counterpart, Israel Space Agency Director Avi Blasberger, and signed a "joint agreement" on cooperation. That one-page agreement "reaffirmed their strong mutual interest in strengthening cooperation" but did not specify any new initiatives for the...

    One of the experiments astronauts are tending to on the International Space Station could electrify space exploration. The experiment centers on a batch of microbes called Shewanella oneidensis MR-1, which arrived at the station in early July. Here on Earth, Shewanella has an unusual skill: It can produce electricity. The experiment is the first step to determining whether the microbes can do so in space as well — and whether humans can harness that ability to make space exploration easier. The bacterium belongs to a group called exoelectrogens, which can create electricity all by themselves, as NASA explains in a...

    With dynamic growth and access to capital seen as primary factors for jumping three places, the US has regained its status as being on the cutting edge of competitiveness in a ranking by the IMD think tank. A competitive ranking of 63 advanced economies published on Wednesday showed the United States improving three positions to return to the top spot, overtaking Hong Kong, Singapore and the Netherlands, and leaving Switzerland behind.As the top five most competitive countries in the world remained the same — changing only in their order — the American economy's comeback was mainly driven by economic performance,...

    The National Guard in Hawaii is warning of new, immediate dangers to people living near the Kilauea volcano some two-and-a-half months after the eruption started. At the same time lava flow is changing the outline of the island itself and creating hundreds of acres of new land where the ocean used to be. The island has grown by nearly 700 acres, the equivalent of more than 500 football fields, reports CBS News' Carter Evans.

    The U.K. Ministry of Defense has unveiled new plans for a new stealth fighter jet called Tempest at the biennial Farnborough Airshow. The announcement coincides with the release of a new Combat Air Strategy, which focuses heavily on sustaining and expanding the United Kingdom’s domestic defense industrial base and international cooperation in that sector, but there are already questions about the project’s viability given the country’s increasingly uncertain political and economic future. Underscoring the emphasis on engagement with the private sector, U.K. Defense Secretary Gavin Williamson offered details about Tempest and the country’s new aerial warfare strategy in front...

    Bloodstains found on the shroud of Turin burial cloth, believed by many to have once wrapped the body of Jesus Christ, are likely fake, according to new research reported in the Journal of Forensic Sciences. In June 2017, researchers at the Institute of Crystallography found traces of blood on the 14-foot-long relic, with initial analysis of the particles discovering "a scenario of great suffering, whose victim was wrapped up in the funeral cloth." The nanoparticles uncovered were found to not be typical of the blood of a healthy person. The Journal of Forensic Sciences report on July 10 revealed that...
