NASA has lost priceless relics of space history, largely because of poor record keeping and follow-through, the agency's watchdog concluded.The inspector general recently found "NASA does not have adequate processes in place to identify or manage its heritage assets."That has led NASA to lose track of items that flew in space, such as "an Apollo 11 lunar collection bag that contained lunar dust particles," and other historically significant items, like a prototype lunar rover that was sold to a scrap yard.NASA told the inspector general's office in a memo that it would develop better processes for dealing with historical items by the spring of May 2020. The agency did not immediately respond to CNN for comment.The rover turned up "in a residential neighborhood in Alabama" and was spotted by an Air Force historian. When contacted by the government, the owner "expressed interest in returning the vehicle to NASA."But the agency lost track of the vehicle because it did not follow through."After waiting more than 4 months for a decision from the Agency, the individual sold the rover to a scrap metal company," the inspector general found. "NASA officials subsequently offered to buy the rover, but the scrap yard owner refused and, realizing its historical value, sold the vehicle at auction for an undisclosed sum."In another instance, NASA lost track of a bag containing moon material, which was eventually sold for .8 million.The "Apollo 11 lunar collection bag" was "seized by the Federal Bureau of Investigation from the home of a former chief executive officer for the Kansas Cosmosphere and Space Center during a criminal investigation," the IG found, then sold at a Marshals Service auction. NASA learned of the bag in 2015 when the purchaser asked the agency to verify its authenticity, but a judge turned down NASA's request to take possession of the bag, and the unnamed individual auctioned it off.As the Space Shuttle program wound down, NASA improved its processes for keeping track of historical artifacts, the report said. But that has not helped the agency recover items dating to the Mercury, Gemini and Apollo space missions of the 1960s and 1970s.Items from that era, the report said, have shown up in online auctions because "NASA freely gave property as gifts to astronauts and other employees and contractors." 2360

More than 190,000 ceiling fans sold at Home Depot in the U.S. and Canada are being recalled after receiving reports that blades were detaching from the fan while in use, which the company said could cause injuries.According to the Consumer Product Safety Commission (CPSC), 182,000 of the Hampton Bay 54-inch Mara Indoor/Outdoor fans were sold in the U.S. in stores and online from April through October 2020. Home Depot also sold 8,800 fans in Canada.The CPSC said 47 reports of the blades detaching have caused two people being struck and four accounts of the blades causing property damage. It was not reported if the people hit were injured.The CPSC said the recalled fans come in matte white, matte black, black, and polished nickel finishes. The fans also came with a white color changing integrated LED light and remote control.UPC #Matte White082392519186Matte Black082392519193Black082392599195Polished Nickel082392599188Consumers are asked to immediately stop using the ceiling fans and inspect the ceiling fans using the instructions.The CPSC says if consumers observe "blade movement or uneven gaps between the blades and fan body or movement of the clip during the inspection," to immediately contact the distributor King of Fans for a free replacement ceiling fan. 1286

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

MIRAMAR, Calif. (KGTV) — Nearly 50 years after 15 men lost their lives at Naval Air Station Miramar, one man recounted his memories hoping to keep their story alive.Monday, Dec. 22, 1969 was Darwin Ludi's first day back from Christmas vacation. He was on rotation at the Balboa Naval Hospital in the morgue as a Navy Corpsman.When he walked in that morning he described the horrifying sight, "there were body bags along the hallway and I was like, 'What is going on?" RELATED: MCAS Miramar dedicates plaque to Marines killed in 1970 training crashHe said the men were unrecognizable. He said the initial shock stayed with him for months and to this day is his strongest memory."We did the autopsies over a couple of days and the smell just lingered," he said somberly.Photos from MCAS Miramar's archives capture the panic and pain. Around 10:30 a.m. one article says the pilot of an F-8 Crusader ejected after reporting low oil pressure and engine seizure. He said he had no control over the plane.After ejecting, the plane veered right, according to the article, straight into a hangar.RELATED: MCAS Miramar crucial training hub, as political tensions rise around the world"They had, from what I understand, probably 60 some people working in the hangar at the time," Ludi said.The article described a 'big ball of flame belch[ed] from the doorway' then more explosions. "With all the like I said ordnances and it was fuel tanks in there, they were blowing up," Ludi said.The article stated at least 12 were injured from the crash, two jets were destroyed, another damaged extensively. The damage initially tallied around million.Fifty years later he hopes telling their story will keep those who made the ultimate sacrifice from being forgotten, "as long as I'm around hopefully things like this come out, because it's important. It's important to the San Diego community."Important especially in the middle of the holiday season. 1944
