Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid. Quantum matter, however, can behave very differently. In the early 20th century, researchers discovered that when helium is cooled, it transitions from a seemingly ordinary gas into a so-called superfluid. Superfluids flow without losing any energy, among other quantum quirks, like an ability to climb out of containers.
Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals is one of the simplest and most efficient methods for generating VUV light, the scarcity of suitable NLO crystals has long been a bottleneck.

Scientists studying the causes of ice ages say that an increase in Antarctic ice levels could be enough to trigger a new ice age that would reverse the current warming of our planet. As climate change continues to cause rising global temperatures that are busy melting the ice caps, scientists are racing to figure out what caused the ice age. Such information could give us a way to reverse climate change and restore the ice caps to normal. Sea level rise is a growing problem that already threatens to swallow islands under the sea. As more ice melts in the Arctic and Antarctic, sea levels will only keep rising, especially when you add glacier melt to the equation.  The question many are asking is how can we reverse this damage? Is there a way to stop global temperature rise and prevent the ice caps from totally disappearing? It may be too late to save many low lying coastal areas and some islands, but there may still be time to save the rest. Multiple strategies have been offered, such as planting billions of trees to suck up the carbon emissions that are causing the greenhouse gas effect, which traps carbon dioxide and other gases in the atmosphere, resulting in hotter temperatures. We could also eliminate carbon emissions so that no new emissions are added. Combining these two strategies offers the best solution. But another strategy could be to cause a new ice age. Causing an ice age?Millions of years ago, a shift in our planet’s natural cycle touched off a series of ice ages, the remnants of which can still be seen today via glaciers and in ice cores. But once the Industrial Revolution began in the 19th century, global temperatures have continued to rise as more and more carbon emissions are produced. Now the world faces a crisis humanity has never faced before. So, is it possible to cause another ice age to reverse the warming trend?
Jansen and postdoctoral researcher Alice Marzocchi studied this carbon balance and hypothesize that the ice caps act as a lid on the ocean surface preventing a lot of carbon from escaping to the atmosphere. This fragile cycle of melting and freezing has been occurring for 2.5 million years, keeping greenhouse gases under the surface of the ocean at bay for many millennia, but that’s all about to change as the ice melts uncontrollably.
 The duo used computer simulations to bolster their theory, however, how this natural system works isn’t totally clear.
First, the atmosphere has to cool just enough for ice to begin building up on the surface, contributing to the natural ocean circulation as we understand it today.
According to their study published by Nature:
In fact, the ice sheets are an incredibly important factor in keeping carbon stored deep under the ocean.
 Indeed, it could also provide a way to stop climate change in its tracks and perhaps even reverse it. Again, it all comes back to reducing carbon emission production and getting rid of the carbon emissions that are already in the atmosphere. Doing that would allow for a cooling that would result in an ice buildup that could trigger a minor ice age, thus setting the clock back on global warming. Causing an ice age may not seem like a good idea, but we need cooler temperatures right now before global temperatures cross a red line that will result in worse droughts and severe water insecurity. Because frozen water is better than no water at all… Featured Image: Wikimedia There is always an ongoing dispute about how old the ancient pyramids really are. Mainstream archaeologists tend to follow an agreed-upon timeline, while others continuously question the dates. Could the Egyptian pyramids really date back hundreds of thousands of years, as some suggest? One thing is clear: The debate may never end. However, if we look at the big picture, there is a good reason to continue asking questions. Pyramids appear all over the globe bearing striking similarities that suggest possible worldwide communication, planning, and advanced technology thousands of years ago. And in one case, a pristine and elaborately-carved pyramid was found deep underwater, giving more support to the idea that it could have been built in the distant past –Before the Great Flood described in worldwide ancient texts. Far away from Egypt, in the vast and secretive nation of China, there is a sunken city and a large underwater pyramid. The location: Fuxian Lake. The lake is the Yunnan Province, covering 100 square miles with a depth of 508 feet. The lake is 1,720 meters above sea level and is one of the largest freshwater lakes in China.
 A professional diver, Geng Wei, found carved flagstones laying under moss on the bottom in 1992. His further explorations, along with Chinese archaeologists with a submarine, discovered sunken city stairways and walls, earthenware, an arena-like structure, and roads. The diver suspected the city might be the site of the legendary ancient city of Yuyuan, said to have disappeared in the distant past. The missing pyramidThe following is from a Chinese news source called China Daily:
The same Chinese news source, which is closely monitored by the communist government, openly tells the story of the underwater city. They say that archaeologists date objects from the site to around 250 CE, and at first suspected that the sunken city matched up with legends of the lost city of Yuyuan. However, after closer examination, archaeologists determined the stone city could not be Yuyuan, as it was constructed of wood and clay, not stone. Furthermore, archaeologists attempting to date material on the stones found the sunken city must be far older. Most notably, the source completely omits mention of any pyramid. On the other hand, Chinese travel guides highlight the pyramid and even compares the findings to Mayan pyramids. From Travel China Guide:
A British new source also made comparisons to Mayan structures.
Ancient Origins reported the pyramid seems to be advanced and described enigmatic carvings found on stones. A rare sun-shaped intaglio carving was found that could date to 1,800-years-old. Other carvings look like masks with faces that aren’t human, as well as symbols that resemble the numbers 0, 1, and the letter y.  For more about this as well as a story of possibly the largest pyramid on Earth in China, see our related article: Meet the enigmatic ‘Pre-Flood’ pyramids beneath Lake Fuxian in China Legends of Fuxian LakeAccording to Cheng Jang Fu Zhi, a book written during the reign of Emperor Daoguang described a flying horse-like animal that lived in the lake, described as white with red spots on its back. It was later described as similar to Pegasus after the flying horse of Greek legends. On October 24, 1991, a fisherman named Zhang Yuxiang was out on the lake on a clear day. A dense fog rolled in, and the fisherman and others on the boat saw a shiny disk-shaped UFO rise out of the water. The craft created waves as it rose, tossing the fisherman’s boat about in the water. Then it shot off rapidly into the sky. (see video below) China Daily reported that a hill west of the lake called Li Jiashan has been the site of regular army patrols, though nobody knows why. The hill was once the site of an ancient battlefield, and thousands of bronze castings were found there. The Li Jiashan hill is known to attract lightning, according to the report.

Juan Ponce de Leon is probably best known for discovering what is now known as the U.S. state of Florida, but he’s also associated with a search for the so-called “Fountain of Youth” which would supposedly make one young again if they so much as bathed in or drank from the water. But as with many things that get mythologized over time, it turns out that Ponce de Leon likely never went in search of any such fountain, according to Ancient Origins.  From Page to ExplorerJuan Ponce de Leon was born in 1460 (though some allege the actual year of his birth was 1474) to a poor family in Valladolid, Spain, and served as a page in the court of Aragon. When he matured, Ponce de Leon became a solider, fighting in the Spanish military campaigns against the Emirate of Granada. But once the war ended, his services were no longer needed, so he decided to become an overseas explorer, hoping that he might gain fame and fortune as a result.  Ponce de Leon trained to be an explorer by joining the second expedition of Christopher Columbus to the New World in 1493. As a result of his service with Columbus, Ponce de Leon was named the military commander and later governor of the island of Hispaniola, which is now known as the Dominican Republic. While serving as governor of Hispaniola, Ponce de Leon heard that another island, San Juan Bautista, was loaded with gold, so he obtained permission from the Spanish royal family to go and explore the island. A Spanish settlement was established on San Juan Bautista and once again Ponce de Leon became governor of what later became modern-day Puerto Rico.  The Fountain of Youth?As an explorer, Ponce de Leon was far from the only consquistador looking to make his name in the New World. And some of his rivals actively tried to bring about his downfall:
 As he searched for the tiny island of Bimini, rumors spread that Ponce de Leon was actually seeking the elusive “Fountain of Youth,” but some historical scholars say that was never the the explorer’s intent:
The court chronicler hated Ponce de Leon, so he slurred him as a fool who was motivated by ego and greed:
 Florida Instead of BiminiAs he continued to search for Bimini, Ponce de Leon instead found Florida, which got its name from the fact that Ponce de Leon landed there during the Easter season, which in Spanish is known as Pascua Florida. A year later, Ponce de Leon was given permission to colonize the region of Florida, but during the expedition the explorer was wounded in a thigh by an arrow. That wound later killed him at the age of 61. But despite meeting his end while attempting to secure his place in history, Ponce de Leon gained a bit of immortality, and to this day is one of the most recognizable names of all the famous Spanish explorers, second only to Columbus himself, who was his mentor in the early days of his career. Oddly enough, however, Ponce de Leon is now associated with the fictional “Fountain of Youth” which it appears was little more than an attempt to discredit him. Instead, it has given him the sheen of immortality all these centuries later. Here’s more on the famed explorer: https://www.youtube.com/watch?time_continue=2&v=lmRbNQBQ5OA Featured Image: Madame Tussauds Orlando – Juan Ponce de Leon by Jared via Flickr (CC BY 2.0) with Fountain via Pixabay by Mabel Amber YouTube Video Here: https://www.youtube.com/embed/lGH4MK9O2J0?feature=oembed&enablejsapi=1 For decades, archaeologists have agreed that Homo sapiens were the first to create and use fire some 400,000 years ago, marking a profound turning point in the cultural aspect of human evolution because it provided a source of warmth and protection. But new data from a team of researchers at the University of Connecticut, working in conjunction with colleagues from Armenia, the United Kingdom, and Spain suggests that early humans such as Neanderthals also controlled fire and had mastered the ability to generate it.  A new article from those researchers has just been published in Scientific Reports, and what it suggests could drastically change our overall understanding of early man:
The work of this team from the University of Connecticut includes archaeological, hydrocarbon, and isotope evidence of human interactions with fire, along with what the climate was like on Earth thousands of years ago. Related: Neanderthals used and recycled an ancient glue made using fire to construct tools  For proof of their theory, the team went to Armenia, where they closely examined Lusakert Cave in the highlands of the country. Gideon Hartman, associate professor of anthropology, and study co-author noted that the hope was to better understand the true history of man and fire:
 Looking at sediment samples, the research team was able to determine the abundance of polycyclic aromatic hydrocarbons (PAHs), which are released when organic material is burned:
 But the researchers also had to try and eliminate the possibility that weather may have caused the fires which were showing up in the scientific data they found in and around the Armenian cave. Once they could eliminate that possible explanation, they would be closer to proving that man did indeed begin using fire far ahead of the established timeline. After rigorous testing, a conclusion was reached:
Related: Archaeologists change view that Neanderthals were cave dwellers With that question answered, the team was able to conclude that early humans before Homo sapiens did indeed have the ability to build and control fire, overturning the long-held beliefs that have guided the scientific community for decades. The next step is to look at other caves and see what clues they may contain:
The questions are endless, but they give us even greater insight into our ancient ancestors and how they acquired much of the knowledge that we now take for granted.
