NATIONAL CITY (KGTV) -- Police in National City are searching for several suspects who reportedly robbed a jewelry store early Tuesday afternoon. According to police, three suspects entered the Eclipse Jewelry store just before 12:30 p.m. The suspects, only described as police as three black men, smashed three to six jewelry cases and got away with an unknown amount of jewelry. RELATED: Good Samaritan picks up diamond ring dropped by jewelry store robber, witnesses sayAfter leaving the store, police say the suspects ran to a getaway car on North 2nd Avenue. Police are looking into whether or not this incident is linked to a string of jewelry store robberies in late 2018 and early 2017. Between December of 2018 and February of 2019, at least three other jewelry stores throughout San Diego County were robbed in a similary manner. Check out the map below to see where the other jewelry stores were located: 924

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

More than 200 small earthquakes peppered California's Imperial Valley on Wednesday night and Thursday morning.The USGS reports that 240 small earthquakes occurred near Westmorland, California, between 4 p.m. local time Wednesday evening into 8 p.m. local time Thursday morning. Most of the quakes measure about magnitude 3.0, with the largest being a magnitude 4.9 quake.The seismic activity continued into Thursday morning, as dozens more small earthquakes occurred in what the USGS calls the "Brawley seismic zone." Dr. Lucy Jones, a seismologist, founder & chief scientist at her center, said it is one of the largest swarms ever seen in the Imperial Valley — and it is historically one of the most active swarms in Southern California. According to the USGS, the area also saw earthquake swarms in 1981 (which included a magnitude 5.8 quake) and in 2012 (which included a magnitude 5.4 quake).The USGS reports that the earthquake swarm will continue to produce small earthquakes over the next seven days, and while there may be a few moderately-sized earthquakes up to magnitude 5.4, the system will eventually peter out.A second less likely scenario laid out by the USGS indicates that a large earthquake between magnitudes 5.5 and 6.9 is possible. A third — and least likely — scenario indicates that an enormous earthquake of magnitude 7.0+ could happen, which would cause "serious" impacts on nearby communities.Luckily, Jones said the earthquake swarm is too far away to have an impact on the dangerous San Andreas."The swarm happening now south of the Salton Sea, near Westmorland is over 30 km south of the end of the San Andreas," she tweeted. "It is in the Brawley seismic zone, a common source of swarms. So far largest is M4.4. Too far from the San Andreas to change the probability of a quake on it." 1828
