As scientists learn more about COVID-19, they are realizing that how people react to the virus could be based on the body's response to viruses like common colds.Meharry Medical College President Dr. James Hildreth says some studies are showing some individuals have T-cell responses to COVID-19 even though they never been exposed to it.He is talking about recent research revealing that some people may have immunity defenders called T-cells which could determine how their body reacts to COVID-19.According to the CDC, when the body fights an infection, the immune system remembers what it learned about how to protect the body against that disease.The body will retain a few specific T-cells known as memory cells - that will alert and help the immune system identify and produce antibodies to attack the foreign germ if it enters the body again."Viruses that look alike can sometimes elicit the same kinds of immune responses," said Hildreth.Hildreth says there are six strains of coronavirus that affect humans going back to the 1960s and some result in seasonal common colds.He says if you were infected with one of these viruses in the past it can determine the severity of the toll COVID-19 would take on your body now."There’s the possibility that a response to one of them gives you a partial to another because they have genetic similarities," said Hildreth.Hildreth says this doesn't mean a person has complete immunity to COVID-19."There’s strong evidence that you may not be immune to the virus, but you’ll have an immune response that recognizes SARS partially just because those two viruses look so much alike."Hildreth says this can help with treatments and even vaccinesThis story was originally reported by Kelsey Gibbs at WTVF. 1756

Back-to-school shopping is an expensive chore in a normal year; this year is anything but normal. But with August upon us, stores are putting out back-to-school displays in anticipation of children needing to learn, whether in the classroom or at home.Two-fifths (40%) of parents with children in K-12 or college anticipate their children will be attending classes in a hybrid environment (both in-person and remote) in the fall of 2020, according to a new NerdWallet survey conducted online July 16-20 by The Harris Poll among over 600 parents. Planning for multiple scenarios could result in the need for increased back-to-school spending, but many may not have the extra money this year.Nearly half (47%) of parents expect they’ll spend less on back-to-school shopping than they otherwise would, due to the coronavirus pandemic, according to the survey. Of them, 40% say it’s because their household income has been affected by the pandemic and related economic effects.On the other hand, one-fifth (20%) of parents expect to spend more this year on back-to-school purchases than they otherwise would, due to the pandemic. Of them, 54% think they’ll be spending more to outfit a home learning environment, and 50% will be spending more to account for supplies for both in-person and at-home learning.“Saving on back-to-school shopping takes some strategizing in a normal school year, but this year poses unique challenges: Not only is it harder to know what students might need, but many families are eyeing big purchases to make remote learning easier, including electronics and desks,” says Kimberly Palmer, personal finance expert at NerdWallet. “At the same time, many families have less room in their budget to make new purchases because of the pandemic.”1. Shop for the short termWhether you’re spending less this year out of necessity or you’re anticipating having to spend more: Buy only what you need. If 2020 has taught us anything, it’s that well-laid plans can change. So purchase what you need to get the school year started and plan to supplement those purchases as the semester unfolds. You may find that some items get less expensive as the seasons change.“Unless you have your eye on a specific type of computer or another item that could sell out, it’s OK to wait to make your purchases until after the school year begins — in fact, that’s when you see many of the best deals,” Palmer says.2. Take advantage of credit card rewardsMore than half (53%) of parents who will back-to-school shop this year plan to use a credit card on those purchases, according to the survey. Putting your expenses on a cash-back credit card could put your money to work for you. You may even reap enough to cover next year’s back-to-school expenses entirely. Just make sure you’re able to pay off the balance each cycle, as interest can quickly negate any benefits.3. Check prices before and after shoppingPrice matching involves comparing identical items at other stores and asking a retailer to match a lower price. The trick may not make sense for a package of pencils, but for clothing, electronics and other higher-dollar items, a successful price match could save you tens of dollars, if not more.Check a retailer’s website for its price matching policy details. Many will also refund the price difference if you spot a cheaper price within a certain time frame after the purchase.4. Team up to buy in bulkRegardless of where your child is learning this fall, they’ll need supplies that other students are also after. By teaming up with other parents, you can purchase things like hand sanitizer and supplies for homework and note-taking in bulk. If your child’s teacher is reluctant to give out parents’ contact information, ask if they would send out yours in a group email so other parents can reach you if they’re interested in group savings.“With many parents focused on at-home learning, you can also find savings by teaming up with other families in your neighborhood on purchases,” Palmer says. “Some communities are forming ‘pandemic pods’ to share the burden of teaching at home and keep kids socialized — pooling school supplies across the pod can spread the expenses and make them more manageable.”5. Shop on tax-free holidaysSixteen states are having sales tax holidays in August 2020. Most of them last through a full weekend, and some even longer. Retailers that offer online ordering for in-store pickup may require you to order and pick up on those particular days to reap the tax-free benefits. The specifics of each state’s holiday vary, but generally, they allow you to purchase certain back-to-school items without paying sales tax.6. Practice and teach thriftinessIf money is very tight, your child might be able to reuse some of last year’s supplies such as their backpack or leftover pencils and notebooks. You can also shop secondhand on sites like Poshmark or thredUP for clothing throughout the school year. And don’t be afraid to ask for help — many schools are putting programs in place that help outfit homes with the technology needed for remote learning.If your child isn’t accustomed to having to make sacrifices like this, use them as a teachable moment. Older kids can learn the complexities of managing a budget, a tool they’ll need in adulthood, and younger ones can learn what saving money means and help you search for the lowest prices.“Some communities are also organizing online volunteer opportunities for high schoolers to help match up with elementary school children who need extra help, which can be a great way to provide learning opportunities to both age groups in a safe, free way,” Palmer adds. “This school year will be unlike any other, which means parents and children will have to get more creative with stretching their back-to-school budgets.”More From NerdWalletWhat to Know Before Laying Down Money for a MattressWhat to Buy (and Skip) in FebruaryHere’s When Everything Will Go on Sale in 2020Elizabeth Renter is a writer at NerdWallet.

As schools begin to reopen, some children will go back and others won't. People are taking different strides and therapists claim it can be an awkward time for families."It's very awkward being around people," mother Valentina Cattaneo said. "It's like, do you put your mask on? Do you take it off? Do they feel weird that you're wearing it? Do you feel weird they are not wearing it?"Cattaneo said being social isn't easy anymore."People are so used to social interaction and when this struck us, it's like people can't be themselves anymore," she said.Playdates in a pandemic can bring up anxiety, even in the form of an invitation. Jennifer Tomko, a licensed psychotherapist with Clarity Health Solutions, said everyone is at various points when it comes to re-entry into life."We're all at different levels of acceptance and risk tolerance," she said.Tomko said respect is key to maintaining friendships, especially with those who are not like-minded."Some people are going to be very tolerant of potential threats and other people are going to be really really cautious, and we just have to respect where everyone is without judgment and don't make it personal," she said. "There is a logical reason you may be hanging out with these people and not those."She suggested making plans for the future."Be apologetic but also state the reasons, the rationale, for why you don't feel safe yet, and if the person is not able to accept that feedback, then you did the best you could," Tomko said.Dr. Chad Rudnick, a pediatrician with Boca VIPediatrics, said an individual's own health has to come first."Right now, in the times of COVID, it's always OK to say, 'No,'" he said. "You never have to feel bad about declining a play date or an invite to go to someone's house or do anything with another family. You shouldn't feel the need that you have to explain what's going on in your family's health history in order to explain why you're declining an invitation."Tomko said getting through this may take time."We have to respect that everybody has a different way of living their lives and a different way of making the decisions that they make, and judging those decisions doesn't do anything for us," she said.This story was first reported by Tory Dunnan at WPTV in West Palm Beach, Florida. 2300

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

As the debate rages nationwide over what to do over a plethora of Confederate monuments, new concern is mounting over a Confederate rally planned for Richmond, Virginia, on Saturday.At the center of the debate is Richmond’s “Monument Avenue,” a collection of statues of Confederate leaders in the former Confederate capital. Back in May, the city’s mayor Levar Stoney said that while he personally believes the monuments are an “endorsement of a shameful past,” he didn’t believe there should be a rush to remove them. He had hoped for a dialogue to take place, and even floated the idea of adding plaques to the statues for more accurate historical context."I think we have an opportunity here in the city to actually be a hub for reconciliation."He created the “Monument Avenue Commission” and even solicited public input in the form of open public meetings. Richmond residents were not shy voicing their opinions.Rita Willis, a former teacher, attended the Aug. 9 public forum to say they are a part of Virginia’s history, whether some like it or not. However she emphasized that if they stay, other statues should be erected that highlight people of other races and ethnicities.George Knight, on the other hand, stood in the auditorium and gave city officials a tongue lashing.“Now is the time to finally get rid of the monuments and replace them with people who actually fought for freedom who actually stood for justice,” Knight said, his voice raising as officials urged him to keep calm. “You lost! Get over it already! Get rid of your participation trophies on monument avenue, get rid of it.”He was met with a spattering of boos as well as cheers.But some attitudes regarding the statues changed following the white nationalist rally last month in Charlottesville, Virginia, which culminated in counter-protestor Heather Heyer losing her life. Stoney is one who’s taken a slightly different position since Charlottesville and believes that perhaps they should now consider taking them down. He wrote in a statement that it had become clear that the statues were being used as a “rallying point for division and intolerance and violence.”The group rallying support around the Robert E. Lee statue on Saturday is a relatively small group out of Tennessee known as “CSA II: The New Confederate States of America.” The group’s president said they were “standing up for their proud heritage” in a nonviolent manner and that any white nationalists or racists who show up to rally with them will not be accepted.He said his message to Richmonders on edge regarding the weekend’s rally is simple: “We are here for peaceful purposes only.”“We will not stand for any violence in Richmond, Virginia.”But the city says they are taking protective measures to be safe. The mayor and police chief announced this week that any objects that can be used as weapons will be prohibited. One type of weapon that won’t be prohibited, however, are guns, as Virginia is an open-carry state.“If you do not respect our city,” Stoney warned, “law enforcement will lock you up."  3084
