NASHVILLE, Tenn. (AP) — Grammy-winning country group Lady A has filed a lawsuit against a Black singer who has been performing as Lady A as well. The group dropped the word "Antebellum" from their name because of its ties to slavery. But blues singer Anita White, who has been releasing and performing music under that name for years, complained publicly that the band never reached out to her. Negotiations between the parties broke down. The lawsuit seeks the court to declare that the band's use of the trademark "Lady A" does not infringe on White's alleged trademark rights of the same name. The band is not seeking monetary damages. 646

Moderna is asking American regulators to allow emergency use of its COVID-19 vaccine. It says its final results show the vaccine is 94% effective.The drug maker says it had 196 COVID-19 cases so far in its study. It says 185 of those participants received the placebo, while 11 got the real vaccine. The 30 people who became seriously ill in the trial didn't get the vaccine.FDA advisors are expected to look at all the evidence on December 17. They'll be checking out Pfizer’s vaccine on December 10.Pfizer and Moderna's success with their COVID-19 trials could impact how vaccines are made in the future.It has to do with how they work. They use what's called messenger RNA (mRNA) technology. The virus' genetic code is injected into the body so it can instruct cells on what antibodies to produce.It hasn't been approved to be used in a commercial vaccine before.“In the future, it's clearly going to be tough to beat RNA vaccines for speed and that's a wonderful thing. Just this demonstration of how incredibly fast they can move has been great. How effective they can be, I think will depend on a particular disease,” said Shane Crotty, Ph.D. with the La Jolla Institute for Immunology.Crotty says the narrowest application for this vaccine technology in the future is a similar situation where there's a new emerging virus."The mRNA vaccine has been tried for other infectious diseases and they have been investigated for cancer. There's a whole area of trying to vaccine against cancer, which has kind of been an elusive target,” said Dr. Alessandro Sette with the La Jolla Institute for Immunology.A big question with an mRNA vaccine is how long its protection will last. While there is encouraging findings, there's no historical comparison to look at.A big thing experts say has helped with a vaccine is there has been a lot of money put towards manufacturing before we even knew it would work.Click here to learn more about mRNA vaccines. 1958

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

Missing Saudi journalist Jamal Khashoggi may have recorded his own death, a Turkish newspaper reported Saturday morning.Khashoggi turned on the recording function of his Apple Watch before walking into the Saudi consulate in Istanbul on October 2, according to Sabah newspaper.The moments of his "interrogation, torture and killing were audio recorded and sent to both his phone and to iCloud," the pro-government, privately owned newspaper paper reported. The Turkish newspaper said conversations of the men involved in the reported assassination were recorded.Security forces leading the investigation found the audio file inside the phone Khasshoggi left with his fiancé, according to Sabah.Upon noticing the watch, Sabah reports, Khashoggi's assailants tried to unlock the Apple Watch with multiple password attempts, ultimately using Khashoggi's fingerprint to unlock the smart watch. They were successful in deleting only some of the files, Sabah reported.However, on its website, Apple does not list fingerprint verification as one of the Apple Watch's capabilities. A representative from the company confirmed to CNN the watches do not have the feature.It was not immediately clear whether it would have been technically feasible for Khashoggi's Apple phone to transfer audio to his phone, which he had given to his fiancee before entering the consulate.CNN cannot independently verify Sabah report and is seeking comment from both Saudi and Turkish officials.On Friday, a source familiar with the ongoing investigation told CNN that Turkish authorities have audio and visual evidence that showed Khashoggi was killed inside the Saudi consulate. But it was unclear how Turkish authorities obtained the evidence.The evidence, which was described to the source by a Western intelligence agency, showed there had been an assault and a struggle inside the consulate. There is also evidence of the moment that Khashoggi was killed, the source said.Turkish security units analyzed how Khashoggi's reported killing unfolded with the use of a translator, according to Sabah.Sabah also reported that investigation units are currently examining all cell phone and landline records from the consulate and the consul general's residence on October 2.Efforts to locate Khashoggi's body are ongoing, Sabah reported.Khashoggi, a columnist for the Washington Post, went into the consulate to obtain paperwork that would allow him to marry his Turkish fiancée. He hasn't been seen in public since.Saudi Arabia firmly denies any involvement in his disappearance and says he left the consulate that afternoon. His fiancée, Hatice Cengiz, who was waiting outside the consulate, says she did not see him re-emerge. Turkey has called on Saudi officials to provide evidence that he left the consulate, as they claim.The Washington Post reported late Thursday that the Turkish government had told US officials that it was in possession of audio and video recordings proving that Khashoggi was killed in the consulate, citing unnamed US and Turkish sources.The audio recording in particular provided "persuasive and gruesome evidence" that a Saudi team dispatched to Istanbul was responsible for Khashoggi's death, the Post reported."You can hear his voice and the voices of men speaking Arabic," one person with knowledge of the recording told the Post. "You can hear how he was interrogated, tortured and then murdered."International pressure has mounted on Saudi Arabia to explain what happened to Khashoggi, a former Saudi royal insider who became a critic of the regime and Crown Prince Mohammed bin Salman, who is known colloquially as MBS.The business world has also signaled its disquiet, with British tycoon Richard Branson?saying he's pulling back from two tourism projects in Saudi Arabia and has suspended discussions with Riyadh about a billion investment in Virgin's space companies. Business leaders have also started pulling out of a key conference hosted by MBS in late October.CNN confirmed Friday that it too would no longer participate in the Saudi Future Investment Initiative conference, known as "Davos in the desert." CNN was a media partner for the event.US Treasury Secretary Steven Mnuchin told broadcaster CNBC he still planned to attend the Riyadh summit despite concerns about Khashoggi's status. 4355
