NASHVILLE, Tenn. -- A Nashville ride-hailing driver is using the money she earns to make meals for the homeless.Kerry Wiles is a full-time scientist at the Cooperative Human Tissue Network at Vanderbilt University Medical Center.When Wiles was diagnosed with breast cancer in 2018, she made a bucket list that included driving for Uber and Lyft."I thought 'I'm going to make a bucket list of everything I've wondered about' and this was on it," said Wiles.Within a couple days, Wiles knew she liked the gig."What I found is I really like talking to the people. I like meeting them and sharing my favorite spots in Nashville," she said.But Wiles also discovered quickly that Nashville's homeless population is sizable and growing."As I was driving around I would notice the same people in the same spots and I noticed a lot of new homeless," she said.A week into it, Wiles began making meals for the homeless."If I have a rider with me, they're kind of amazed," she said.Wiles uses the fares and tips she receives to pay for the lunches. She hands them out during her shifts."If you leave a tip I match it... everything I need to make the lunches is basically subsidized by my tips and rides," she said.Wiles has her route down to a science now. On Saturdays and Sundays, she typically hands out more than 100 lunches.This summer, a customer started to help after hearing about what she does."It's the best thing in the world," said Ryan Caldwells. "It's a humbling experience. When I was a bellhop, I would see people freezing and under bridges and it just didn't sit well in my soul.""We started talking about his goals and dreams and he said he wanted to work with the homeless. I love having his help. He's energetic and an amazing 24-year-old kid," Wiles said.Recently, the duo started writing down the shoe sizes of people in the homeless community to get them boots for the colder months.WTVF's Hannah McDonald asked, "How do you fit this all into your week?""What's important you fit into your week. You just have to determine what's important. When you stop and evaluate life, there are a lot of things that become important to you whether that's the legacy you leave behind or the ability to inspire someone else," said Wiles.Learn more about Homeless Helpers Lunches on Facebook.This story was originally published by Hannah McDonald at WTVF. 2361

NATIONAL CITY, Calif. (KGTV) -- A car flipped into the front yard of a home in National City late Sunday night, police say. According to police, the crash happened on the 2500 block of Ridgeway Drive around 11:30 p.m. Police say the driver of the vehicle somehow lost control of the vehicle, flipping over and landing in the front of the home. The car then caught fire, but crews were able to quickly extinguish the flames before they spread. According to police, the crash took out a fence, street sign and a mail box. The driver fled the scene after the crash, sparking a hit-and-run investigation. 609

MURRAY, Utah – Dr. Todd Vento has spent most of his professional life preparing for the worst-case scenario.“I still have a lot of connections because of things I’ve done in the past,” said Dr. Vento while sitting in the lobby of Intermountain Medical Center in Murray, Utah.He is an infectious disease specialist who previously worked for the Department of Defense, managing the Ebola outbreak in West Africa.He’s since been recruited to fight on the COVID-19 front lines.“When you prepare and constantly live in that world of preparing for a true threat, you do expect that this could happen,” Vento said.In video provided by Intermountain Healthcare and University of Utah Health, you can see states in the Mountain West are reaching a critical tipping point.The talk of moving to a crisis level of care is imminent.One example, the Utah Hospital Association is reporting double the numbers of COVID-19 patients in hospitals from two weeks ago, and five times the number of patients from two months ago.So, what happens at hospitals when numbers surge? The process of load leveling happens first.“(Load leveling is) balancing out where the patients are so you don’t have one facility that might have 110% of capacity, while another facility is at 70%,” Vento said.A patient management system called “Care Traffic Control” covers seven westerns states. Like other systems in the country, it tells first responders where they can take patients.Next comes contingency care.“That contingency plan might be that we need to take care of more COVID-19 patients, so that means we convert another hospital that takes care of non-COVID-19 patients,” Vento explained.Part of the contingency plan also means canceling noncritical surgeries.Finally, there are crisis levels of care.“The concept of the term, crisis standards of care really gets down to a similar concept used in combat and the military,” Vento said. “I know that may sound harsh, but it’s really about the triage process.”That means doctors will be forced to make tough decisions about who gets care and what that will look like.As many states smash records of COVID-19 cases, health care workers are being stretched thin and asking for help.“It’s up to us to allow all our livelihoods to continue,” Vento said. 2276

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
