More than a million chainsaws from Harbor Freight Tools are being recalled because the power switch can malfunction causing a serious injury hazard. According to the Consumer Product Safety Commission, even after the power switch is moved to the "off" position the chainsaws can continue to operate.Harbor Freight Tools has received 15 reports of chainsaws continuing to operate after being turned, resulting in three laceration injuries — including one serious injury to the arm requiring stitches.The recall includes two models of 14-inch chainsaws sold under three different brand names: 623

NASA announced Monday that two new studies show that there may be more water on the moon than previously thought.In a press conference, NASA said that two studies published in the journal Nature Astronomy said that data gathered by a lunar orbiter and an airborne telescope detected the presence of molecular water molecules on the sunlit surface of the moon.Previously, NASA speculated that most of the water on the moon was located on the shadowy surface that is not lit by the sun.The study opens the possibility of using that water as a resource, allowing for longer missions on the moon's surface that would require astronauts to live there for extended periods of time. 683

MURRIETA, Calif. (KGTV) -- The contractor involved in Monday’s deadly gas explosion in Murrieta did not call 811 as required by law, according to officials. One SoCalGas worker was killed in the explosion and more than a dozen people were injured. If a homeowner or contractor plans to do any digging into the ground, there must be a call placed to 811 two working days in advance, according to state law. Investigators say a solar company was working on the Murrieta home when the explosion occurred. That company, Horizon Solar Power, would not specifically address the incident. A spokesperson told Team 10: “Yesterday, four members of our team were at the site of a residential explosion in Murrieta. We are working with authorities and collecting facts to better understand what happened. Our primary thoughts are with the people who were injured and their families, including with the family of the person who lost his life.”An SDG&E spokesperson said 811 must be called for projects including landscaping, fence, and patio projects. In San Diego County when you place that call, SDG&E will mark the location of buried utility owned pipelines and other lines. The service is free.RELATED: Utility worker's body recovered after Murrieta house explosionSDG&E receives between 12 to 13,000 Dig Alert location requests each month. Last year, utility crews were called to repair approximately 306 natural gas lines damaged due to construction or landscaping, according to a spokesperson. This year so far, there have been more than 90 preventable gas leaks. Starting July 1, 2020, the new California Underground Facilities Safe Excavation Board (Dig Safe Board) will begin enforcement, according to SDG&E. Enforcement will include anything from training classes and/or fines up to ,000. The Dig Safe Board is responsible for issue fines. 1866

Mysterious packages are popping up on Medicare recipients’ doorsteps and the Federal Trade Commission said it’s part of a rising scam."That’s a back brace,” Anna Miller, a 94-year-old Medicare recipient said as she rifled through a package delivered to her home.Inside the box was a back brace, shoulder brace, and a couple of other pieces of medical equipment, the items came bundled together in a box addressed to Miller."They must have thought I was in bad shape to send me both of them in one box,” Miller joked.She said she never ordered any kind of medical device."I thought it was terrible because I figured it was false,” Miller said.As it turns out, her Medicare account got charged for the back and shoulder brace. It’s a scam the FTC said is on the rise targeting Medicare dollars and personal information.Miller reached out to Medicare to see what was going on. "They just said they'd look into it and they questioned me,” she said.Medicare followed up, sending a letter confirming an investigation into the matter. Meanwhile, the FTC is warning Medicare recipients to be aware.If someone calls and says they're with Medicare and offers you a “free” or “low cost” brace, hang up right away.Medicare will never call you with such an offer. Never give your Medicare or other personal information over the phone to anyone.If you do need a brace or medical equipment, talk to your doctor. Sellers on the phone don’t know what you need.Lastly, don't accept medical equipment you get in the mail unless you or your doctor ordered it. You don't have to pay for things you didn't order.2 Works for You Problem Solvers reached out to the company listed on the box sent to Miller, but have not heard back.If you are the victim of suspected Medicare fraud, CLICK HERE to report it to Medicare or the FTC immediatelyThis story was first reported by Cori Duke at KJRH in Tulsa, Oklahoma. 1894

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
