Mississippi Gov. Tate Reeves has signed a landmark bill that retires the last state flag bearing the Confederate battle emblem. The Republican governor signed the bill Tuesday afternoon, just two days after legislators passed it. Amid international protests over racial injustice, Mississippi was under increasing pressure to lose a symbol that many see as racist. The state had used the flag since 1894. Mississippi will not have a flag for a while. A commission will design a new one that cannot have the Confederate symbol and must have the phrase, “In God We Trust.” Voters will be asked to approve the new design.The Confederate battle flag is losing its place of official prominence in the South 155 years after the end of the Civil War. Mississippi’s Republican-controlled Legislature voted Sunday to remove the Confederate emblem from the state flag. Other states took action previously. NASCAR, meanwhile, has banned the rebel banner from its car races. The flag with the familiar X design is still visible along Southern highways and in some stores. It's far from being banished in the region. But even flag supporters are surprised by the speed with which change is taking place amid a national debate over racial inequality. 1244

Neanderthals may not have been that different from us, after all.New evidence reveals that they created the world's oldest known cave paintings and even wore seashells as body ornaments. Both behaviors suggest that they thought symbolically and had an artistic sensibility like modern humans. Two studies published Thursday in the journal Science detail the latest findings."Undoubtedly it is showing that Neanderthals were thinking and behaving just like modern humans," Alistair Pike, co-author of the studies and professor of archaeological sciences at the University of Southampton, wrote in an email."We should no longer think of them as a different species, just humans in different places," he said.The new findings of symbolic thinking show that Neanderthals and modern humans were cognitively indistinguishable, the researchers said.Cave paintings and artifacts like painted seashells have long been regarded as the work of early modern humans, who were thought to have more advanced cognitive abilities than Neanderthals. Dating cave paintings can be a difficult process, and unreliable techniques never allowed for the possibility that these could be the work of Neanderthals.Until now, that is. A new technique called Uranium-Thorium dating is less destructive, is more accurate and can go back further in time than other methods. U-Th dating looks at the deposits of carbonate on top of the paint, which contain traces of uranium and thorium that indicate when those deposits formed. That allows the researchers to determine an age for what's under the deposits.The researchers applied this technique to paintings in the La Pasiega, Maltravieso and Ardales caves in Spain, which had never received "robust" dating. The paintings include red and black images of animals, dots, lines, disks and other geometric signs. There also are engravings, hand prints and hand stencils.Those hand stencils are particularly significant, and not just because they represent the hand size of a Neanderthal."A red line, a red dot or even a positive hand print could potentially be made 'accidentally,' " wrote Dirk Hoffmann, lead author of the studies and archaeologist with the Max Planck Institute for Evolutionary Anthropology, in an email."Of course, I am sure that this is not the case, since you would still need to bring [in] light and pigment, but one could argue that all you need is some pigment on your hand when you lean against a wall. A hand stencil cannot be explained like that. You have to hold your hand against the wall and the deliberately spray pigment over this. This is why we emphasize the hand stencil."The dating revealed that the cave art was created more than 64,000 years ago -- 20,000 years before modern humans appeared in what is now considered Europe.The shells were found in the Cueva de los Aviones, a sea cave in southeastern Spain. They are unique because they are perforated with holes and colored with red and yellow pigment. Others served as containers for the mineral pigments themselves. The pigments were used on the shells but could have also been used for the cave paintings and even as body paint.The deposit layer containing the shells dated to 115,000 years ago, which is even older than other shells recovered in Africa that were dated to modern humans."The standard archaeological interpretation of such finds is that they are body ornaments," Hoffmann said. "Similar finds were made in Africa or the Levant with similar age. In Africa or the Levant, these were made by modern humans, in Spain Neanderthals made them. So in terms of symbolism, early modern humans and Neanderthals were similar."The researchers are absolutely confident in their dating technique."We have spent 10 years refining the technique and have numerous quality controls," Pike said. "The dates respect the growth axis of the deposits we are dating, the oldest closest to the painting, the youngest at the surface."Once modern humans left Africa and migrated to Europe and other areas, mixing with the Neanderthals would've been inevitable. The researchers believe that the Neanderthals created this artwork on their own, without being influenced by any other population. But it's possible that they exchanged symbolism or that Neanderthals influenced the art and symbolism of modern humans. Modern humans were capable of symbolic behavior, so it "turns the who's copying who debate on its head," Pike said."The idea that culture only evolved with modern humans no longer makes sense," Pike said. Hoffmann suggested that Neanderthals now be referred to as "very close cousins" of modern humans.Is it possible that anyone else may have created the cave paintings?Pike said it is incredibly doubtful that a population of early modern humans migrated to Europe so early without any other evidence to suggest it."We cannot of course rule out that pre-Neanderthal populations made the art," Pike said. "This sounds like a project for the future."Hoffmann, Pike and their colleagues want to use their new dating technique in more caves in Spain, as well as France and Italy -- and anywhere else Neanderthals are known to lived.The findings also raise new questions for researchers."How far back does symbolic behavior go? Can it be traced to the last common ancestor of modern humans and Neanderthals? This is perhaps where we should be looking," Pike said. 5398

Milwaukee Mayor Tom Barrett says he’s concerned after seeing video of police using a stunning and arresting?a Milwaukee Bucks player Sterling Brown.The video is expected to be released soon, possible later this week. Police are reportedly bracing for backlash from the release of that video. This incident took place on the south side of Milwaukee in January. Police were called to a Walgreens because Brown was illegally parked across two handicap spaces. The officers say they tried to talk to Brown but had to deploy their stun guns to arrest him. Since that time, the arrest has been the subject of a police internal investigation."I have some of the same concerns that the chief has expressed over the video. I'm going to let the release of that speak for itself, but yes, I definitely have concerns after watching that video,” Barrett said. The mayor indicated that Police Chief Alfonso Morales had a similar reaction after seeing the video. Brown was not charged in the incident. However, he did receive a parking citation.  1089

  

MT. LAGUNA, Calif., (KGTV)-- Last weekend, thousands of San Diegans headed to the beaches and mountains to get a breath of fresh air. Many ignored the Governor's stay-at-home order and social distancing.With more snow in the near future, some residents in Mt. Laguna fear tourists will bring in the Coronavirus with them. Children playing in the snow: it's cute and seasonal in East County. But Mt. Laguna resident and business owner Nica Knite says, please stay away. "It's only been a few days people, you could hang at home for a few days. Come on," Knite said. Last weekend, Knite was appalled to see hundreds of cars lined up along Mile Marker 19 on Sunrise Highway. Families seemingly ignored social distancing rules. "The idea of recreating outside and going for a walk might seem like a healthy thing to do. But if people are playing in the snow and someone coughs on that snow and your kid falls onto that same snow, they have the opportunity to contract the virus," Knite said. "So it becomes a giant petri dish of danger."Scientists say COVID-19 could have an easier time surviving and reproducing in colder temperatures. It's because of the large crowds and cooler temperatures that on Sunday, Cleveland National Forest Rangers closed all their campgrounds, day-use areas, and two of their most popular trails: Three Sisters Falls and Cedar Creek Falls. "When you're hiking the trails, they're very narrow, and with the number of people we had, they absolutely could not have any kind of social distancing," Mike Kobliska, Assistant Public Information Officer of the Cleveland National Forest, said. Kobliska says if you are caught in a restricted area, you face a misdemeanor: up to ,000 fine and/or six months in Jail. Mt. Laguna Lodge owner, Tom, says he limits the number of people in and around the store at all times. "If we see somebody sitting too close on our front porch, we ask them to get away, and everybody has been pretty understanding," Tom said. But Park Rangers want people to be even more understanding. "The messages still stay home stay home stay home," Kobliska said. "We are still in this crisis. We are all in this together. We are trying to do the best that we can.""If we end up with cases out of the small rural areas, then you're going to spoil it for everyone," Knite said. They say please, do not risk your own health and the 57 people who call Mr. Laguna home. 2414

  

NASA and SpaceX are preparing for a historic launch Sunday and a Cal Poly graduate will be at the controls in the cockpit. Victor Glover will pilot the NASA SpaceX Crew 1 mission to the International Space Station. The Southern California native and 1999 Cal Poly engineering graduate often sought advice during college, and still does today, from his professor and academic advisor Dr. Dan Walsh. "Victor was very intelligent. Victor understood that the best long term plan is a series of very excellent short term plans," Dr. Walsh told KSBY. "My goodness, where he is now sort of speaks for itself." Glover came to Cal Poly in 1994 on a wrestling scholarship. During his junior year, he was a walk-on for the Cal Poly football team and says athletics has always played a key role in his life. After graduating from Cal Poly, Glover joined the Navy and became a pilot. He is an active-duty Navy aviator with 22 years of service. 940
