This Scientist In England Has Just Revealed He's Solved An 875 Year Old Mystery

A retired professor thinks he has found the location of King Arthur's Camelot. Back in 2016 a rather strange breakthrough was made, one that would take us into the past. A retired professor, Peter Field, is an Arthurian literature expert who used to teach at Bangor University in Wales. For this research of his, however, he has expanded into geography as well as his usual historical and literary expertise. Field believes he has tracked down the legendary castle of Camelot. I am sure we have all heard of the King Arthur legends and, of course, tied to a king is his castle. Camelot is the castle where King Arthur held court over 1400 years ago, though, as is the case with legends, we are unsure if he ever existed at all, never mind his castle. Nonetheless, let us presume that Camelot is indeed a real castle. Well, Professor Field believes he has pinpointed the site where it once stood. The site of an ancient Roman fort called Camelodenum in Slack West Yorkshire, England. In 500 AD, the believed time of King Arthur, this would have been a logical site, as the king is believed by some to have been a military expert defending Britain rather than having genuine royal blood. Field described his discovery as quite by chance, going on to elaborate that he was simply looking at maps when the image began to make more sense. He commented, I believe I may have solved a 1400 year old mystery. While his suggestions are yet to face scientific scrutiny under peer review, this is a promising hypothesis to say the least. Some evidence that could support Field's theory is that Camelodenum, as a word, could have evolved, linguistically speaking, into the word Camelot. As we use language over time, it adapts, adjusts and becomes more efficient for speakers. It is entirely plausible Camelot is derived from the word Camelodenum. Slack might seem like an odd choice of location for a castle to protect against invaders, seemingly because placed in the middle of nowhere, though it could also make for an ideal spot to quickly disperse British troops to any coast or direction. To confirm this theory, we need some sort of archaeological proof. But how do you find proof of a man we are not sure even existed? Some have suggested that the King Arthur, with a round table and wizard pal Merlin, is actually an amalgamation of a number of British rulers, immortalised together in one big story. Others believe he exists but had his stories exaggerated, and others think he is an entertaining legend, but nothing more. Future research can only bring more answers, though for now we will be left with a few more ideas to answer our questions in the future. The oldest known human footprints in North America discovered at National Park. Up until this next discovery, archaeologists believed that humans first appeared in North America 11,000 to 13,000 years ago, basing this judgement on stone spears found scattered throughout the continent. However, they have now uncovered what is thought to be the oldest known human footprints in North America, dating back to a whopping 23,000 years ago, during the Ice Age. That is a staggering ten millennia before we thought humans had ever inhabited North America. Previously, it was thought that humans could not have expanded into the lands of America this far back in time, as massive glaciers, referred to as the Last Glacial Maximum, would have greatly obstructed their path. The originally speculated dates made more sense, as 13,000 years ago humans would have been able to cross from Asia to North America once the Ice Age period was over and corridors were ice-free. The new archaeological find showcases 60 human footprints, being most likely those of children and teenagers it is thought, with the occasional adult print judging on sizes. The discovery also tells us more about how these settlers used to interact with each other. This revelation is set to completely upturn existing theories of past human existence and population patterns. Histories manager David Bustos found the footprints in White Sands National Park of New Mexico, and they were then analysed using carbon dating techniques on embedded seeds found within them. It now calls into serious question the validity of previous estimates that humans first walked through North America 13,500 years ago. Instead, these theories have been revised to suggest that our predecessors could have crossed from Asia to the Americas as early as 26,000 to 19,000 years ago. Thinking more about where the footprints were found, it is thought that two ancient Apache trails used to cross what is now the national park. The descendants of the original Apache settlers are referred to as Mescalero Apache. While it is a hugely game-changing discovery, Bustos reminds us that it is also sad to think of how much other insight we could have lost to soil erosion in the area. Nonetheless, the discovery shows not only how far we have come in terms of scientific progress, but that sites such as this national park still have a wealth of history waiting to be found if we can preserve their contents well enough. China is building a smog-eating forest city. Pollution is something impacting every corner of our Earth. While messages to care for our environment often feature pleas to save Arctic animals, like our friends the polar bears, it is not just the Arctic that is suffering. In some places, the air pollution is becoming so severe that the air is considered unhealthy for humans. One of these places is Nanjing, in the east of China. We use the Air Quality Index to assess the safety of the air. This uses a scale of 0 to 500, with higher numbers showing worse pollution. Even without the Air Quality Index, it is clear to see that there is thick smog in Nanjing, as in many urban cities, but the air quality clocks in at a whopping 132, meaning it is considered unhealthy, especially for members of the public with respiratory diseases and illnesses. Stefano Bari-Arcacetti, an Italian design firm, has a plan to help reduce the smog and air pollution in cities. The company thinks towers of plants could help bring us closer to a safer environment. The company built two skyscrapers covered in flora, bringing in 1,100 trees and 2,500 cascading shrubs on rooftops and balconies. Named the Nanjing Green Towers, they now stand tall, helping the city since their construction, beginning in 2017. Stefano Bari-Arcacetti built a similar two-tower complex in Milan, with others popping up across the world, such as in Switzerland. These towers are just the They aim to have a forest city created in Nanjing that features multiple skyscrapers like these towers, with lots of green space, creating as much improvement as possible. These vertical forests are a brilliant idea. They are space-conscious, yet help our environment, collecting 25 tonnes of carbon dioxide each year and producing 60 kilograms of oxygen each day, per tower. However, 4.7 metric tonnes of carbon dioxide are produced by the average vehicle annually, meaning the towers only cancel out five cars each. This is why a forest city could take these slight improvements to a huge leap forward. These ideas and designs sound incredibly futuristic. They are becoming incredibly necessary. The climate crisis is happening now, and change needs to happen. Plants and forests can help, but each of our actions count too. But what do you make of these recent discoveries?
