Montgomery County, Maryland Police reported Laura Wallen, a pregnant high school teacher who went missing last week, has been found dead. According to Montgomery County Police Chief Tom Manger, Wallen's body was found in a wooded area in Damascus, Maryland. Police have arrested her boyfriend, Tyler Tessier.Tessier was present with Wallen's family during a press conference on Monday. Police had already identified him as a person of interest in the case. Detectives asked the family to invite him to speak as part of the investigation. During the press conference, Tessier pleaded for Wallen to come home."There's so many people, so people that miss you," he said Monday. "There's so many people that were out looking. We haven't slept, we haven't eaten. We're just looking and praying that you're safe and I'm asking that you can just let us know that you're safe."Police have not determined a motive in the case, though during Wednesday's update, police said Tessier was living at several addresses, including one in Damascus.  1079

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

More than 30 states are reporting increases in opioid related overdoses and those from other drugs during the pandemic, particularly involving fentanyl, according to the American Medical Association.The government has taken steps to curb deaths during the pandemic by allowing for more flexibility in prescribing medications for opioid use disorder and lifting other restrictions on pain medications.Meanwhile, the National Safety Council is calling on businesses to get ready for an increase in substance misuse in the workplace.“Employers not only have a responsibility, they have a call to arms here to make sure as they bring employees back to work, that they are directly addressing their mental health and providing them the resources that they need to be able to navigate,” said Lorraine Martin, President of the National Safety Council. “It’s just as important as the PPE and sanitization for hygiene that we will all need to have when we come back to work.”Martin recognizes mental health and substance misuse are often interconnected.Now, with the additional stress and unrest related to George Floyd’s death on top of COVID-19, people may be self-medicating even more.The National Safety Council put out resources and tools to help businesses help struggling employees, but they believe the most important thing leaders can do is talk about it.“The most mature companies are addressing this head on,” said Martin. “We know that substance misuse is a disease, not a decision, and if you can come at it with that attitude and make sure you create that safe space for your employees, that can make all the difference.”Not addressing substance misuse is a serious threat to worker safety and costs a lot of money in terms of productivity, absenteeism and workers compensation claims.On the other hand, employees that work through these issues with their employer often come out on the other side more loyal and productive. 1937

Most new moms can relate; after being stuck inside with a newborn for several weeks, getting outside for fresh air and a different view is important.Mei Xiang at the Smithsonian National Zoo in Washington, D.C. took her newborn panda cub outside the den recently and into the main enclosure.It was a short field trip for the pandas, with Mei Xiang gently nudging her cub along the floor and keeping them out of the smaller den space.These field trips will get longer and more frequent as the cub gains more strength.At eight-weeks-old, the cub is practicing crawling and is not expected to take steps until closer to three-months-old.Zookeepers say the cub is packing on the pounds and has grown a coat of thick, wooly fur, able to help it regulate its body temperature. This means the cub can sleep on the floor of the den next to its mom. 848

Nationally, the number of people filing for new unemployment benefits is still historically high. It rose last week to 898,000.This comes as the number of people experiencing long-term unemployment is growing too. The number of people out of work for more than 27 weeks increased by 781,000 in September. It's now at 2.4 million, according to the latest data from the U.S. Department of Labor.Usually, it's harder to get a job the longer you are out of the workforce, but that may not be the case now.“If you are in one of those situations, you should take comfort in the fact that there is a lot more understanding right now from hiring managers and it's OK to talk about the fact that you are a casualty of the pandemic,” said Blair Decembrele Heitmann, LinkedIn career expert.Heitmann recommends if you're taking on a side hustle now to pay the bills until you can get a full-time job. Try to look for something you can market to a future employer, something that goes along with a long-term career goal you have.“When it comes to explaining a career gap on your resume, really talk to the recruiter and showcase what you've done in that time to make sure that you're more marketable,” said Heitmann. “Whether it be taking a course or networking with your contacts, you want to really show you used the time wisely.”Something else that may help you get noticed right now is adding the "open to work" feature to your LinkedIn profile.LinkedIn has found 40% of people who include that message get more calls and emails from recruiters. 1544
