This human footprints found in Tabuk is 85,000-year-old

Tokyo: Human footprints dating back to about 85,000 years have been discovered on the banks of an ancient lake in the Nefud Desert in Tabuk region, Prince Sultan bin Salman, president of the Saudi Commission for Tourism and National Heritage (SCTH), announced in Tokyo on Thursday. This amazing and rare discovery points to a new understanding of how our species came out of Africa en route to colonizing the world. Prince Sultan’s announcement came on the sidelines of his visit on Thursday to the exhibition entitled “Trade routes in the Arabian Peninsula – the magnificent antiquities of the Kingdom of Saudi Arabia throughout the ages.” The exhibition, organized by the SCTH in the Japanese National Museum in Tokyo, is scheduled to end on Sunday. A joint Saudi international team discovered traces of several adults who were scattered on a muddy land in an old lake — each heading to a different destination — in the northwest of Saudi Arabia, Prince Sultan said, according to a Saudi Press Agency (SPA) report on Friday. The research team included the Saudi Geological Survey, the SCTH, King Saud University, the Max Planck Foundation for Human History, Oxford University, Cambridge University, Australia National, and the University of New South Wales in Australia. Prince Sultan said the age of the footprints coincides...

3-D Printed Food with Custom Taste and Texture: Could It Change How We Eat?

Credit: Jin-Kyu Rhee, Ewha Womans University Researchers have 3-D printed food with customized texture and body absorption characteristics.  Imagine a home appliance that, at the push of a button, turns powdered ingredients into food that meets the individual nutrition requirements of each household member. Although it may seem like something from science fiction, new research aimed at using 3-D printing to create customized food could one day make this a reality. A: Food materials are pulverized under ultra-low temperature close to -100 degrees Celsius. B: Micro-sized food materials are reconstructed into a porous film-shaped material by jetting bonding an agent under optimized water content and heat conditions. The process to build film-type materials is repeated layer by layer to form to a three-dimensional food block. C: The exterior of foods and internal microstructure of a food block with specific porosity is designed to give texture with controlled human body absorption while eating and ingesting. Jin-Kyu Rhee, associate professor at Ewha Womans University in South Korea, discussed his new research and the potential of 3-D printing technology for food production at the American Society for Biochemistry and Molecular Biology annual meeting during the 2018 Experimental Biology meeting to be held April...
