Example Input: "On Nov. 27, 2013, a Madison-based liberal advocacy group used a mass email to promote protests that were planned against Walmart stores for two days later -- Black Friday. The demonstrations aimed to ""expose Wal-Mart’s shameful labor practices and support workers,"" according to One Wisconsin Now, which then made this claim: ""The Walton family, which owns Wal-Mart, controls a fortune equal to the wealth of the bottom 42 percent of Americans combined."" That reminded us of a March 2011 claim by filmmaker and liberal activist Michael Moore. He said in a Madison speech that 400 Americans have more wealth than half of all Americans combined. Based on online hits, it became one of our most popular fact-checks ever. So we wondered about the Walmart claim. Wealth, not income In the days before and after Black Friday, leaders no less prominent than President Barack Obama and Pope Francis decried the extent of income disparity in the United States and around the world. Obama called the growing income gap a ""defining challenge of our time."" The pope said that while the earnings of a minority ""are growing exponentially, so, too, is the gap separating the majority from the prosperity enjoyed by those happy few."" Walmart, of course, is a big target. According to Forbes, as of May 2013 the international retailer had $469 billion in sales and 2.2 million employees, including 1.3 million in the United States. The corporation has been criticized for low wages; and in December 2012, PolitiFact National rated as Mostly  a claim that more Walmart employees are on Medicaid and food stamps than other companies. But let’s be clear up front: Although income and wealth are related, they’re not the same. Wealth is commonly measured in terms of net worth -- the value of a person’s assets minus liabilities. So, things like savings and retirement accounts, minus what is owed on a home mortgage, credit cards, etc. That means a person with heavy debt can have little wealth, or negative wealth, even while earning a six-figure income. One more point before we get to the wealth figures. Walmart was founded by the late Sam Walton, who opened the first store in Arkansas in 1962. Walmart incorporated in 1969 and became a publicly traded company a year later. So, Wal-Mart is not family owned, but rather owned by its stockholders; on the other hand, according to Bloomberg and other news reports, the Walton family members still have control of the company, owning about half of the shares. Group's evidence Scot Ross, One Wisconsin Now's executive director, told us his evidence to back his group’s claim is a July 2012 article by economist Josh Bivens, research and policy director of the liberal Economics Policy Institute in Washington, D.C. Bivens wrote that in 2010, the wealth of six Walton family heirs was $89.5 billion, 22 percent higher than in 2007. Meanwhile, the median wealth of American families in 2010 was $77,300, nearly 39 percent lower than three years earlier. (Median wealth refers to the American family that is exactly wealthier than half of all families and less wealthy than half.) As for measuring one against the other, Bivens said the Walton family wealth in 2010 was as large as the wealth of the bottom 48.8 million families in the United States, or 41.5 percent of all American families. Rounded up, 41.5 percent would be 42 percent, the figure One Wisconsin Now claims. But let's keep shopping around a little. Similar claim It turns out that a statement nearly identical to the one made by One Wisconsin Now was uttered in July 2012 by U.S. Sen. Bernie Sanders, a Vermont independent who caucuses with Democrats. Sanders said the Walton family owns ""more wealth than the bottom 40 percent of America,"" a claim PolitiFact National rated . Our colleagues found that Sylvia Allegretto, a labor economist at the University of California, Berkeley, compared the Waltons’ cumulative net worth with that of the overall population, as cited in the Federal Reserve’s Survey of Consumer Finances. That survey was published in August 2012. Allegretto found that the Waltons’ wealth in 2010 was valued at $89.5 billion -- equal to the entire bottom 41.5 percent of American families. The 2010 figures are the latest available for doing comparisons with the net worth of the overall population. But we found, using the Forbes 400 list for 2013, that the wealth of six of Sam Walton’s descendants has continued to grow. Here are their rankings and their wealth: No. 6 Christy Walton (daughter-in-law), $35.4 billion No. 7: Jim Walton (son), $33.8 billion No. 8: Alice Walton (daughter), $33.5 billion No. 9: S. Robson Walton (son), $33.3 billion No. 95: Ann Walton Kroenke (niece), $4.7 billion No. 110: Nancy Walton Laurie (niece), $4 billion Total Walton family wealth: $144.7 billion. A note before we close: Allegretto told us the housing crisis is a key reason that the gap between the Walton family wealth and the wealth of other American families has grown. More Americans were left with ""negative wealth"" because they lost their biggest asset -- their home -- and often significant amounts of their savings, as well, she said. Our rating One Wisconsin Now wrote: ""The Walton family, which owns Wal-Mart, controls a fortune equal to the wealth of the bottom 42 percent of Americans combined."" For comparison purposes, the latest data available, for 2010, the figure is 41.5 percent. To comment on this item, go to the Milwaukee Journal Sentinel's website."
Example Output: The Walton family, which owns Wal-Mart, controls a fortune equal to the wealth of the bottom 42 percent of Americans combined.

Example Input: A new generation of hoop activists is putting another spin on the hoop, which ancient Greeks fashioned from grapevines and used to exercise the hips. Circus hooper Marawa Ibrahim, known professionally as Marawa the Amazing, lives a nomad’s life performing and teaching hula hooping around the world. “Fitness hooping is what I’m really into. Even at circus school I developed a workout using core muscles to push the hoop,” said Ibrahim, who can spin 133 hoops simultaneously and has appeared on the UK reality show “Britain’s Got Talent.”  The 32-year-old Australian said anyone, regardless of age or fitness level, can keep the hoop spinning but choosing the right size hoop is essential. “You can’t hoop with a kid’s hoop. When you were a kid you were half as tall,” she said, adding that a hoop should reach to the hips, at least. “I used to teach a gym class of overweight women. I made hoops that were almost up to their armpits and they could do it.”  Proper technique also means balance. Even the pros can develop lopsidedness, she said, so spin in both directions in order to tone the body evenly, head to toe. Kelly Strycker is the director of Chicago Hoop Dance, a community-based collection of performers, teachers and students who practice hooping as a form of moving meditation similar to Yoga, or Chi-gong, the Chinese system of exercise and breath control. “There definitely is a circus overlay in hoop dance,” said Strycker, adding toned muscles and weight loss are common benefits. “It tends to be a fitness workout because of the nature of the movement.”  Strycker said hoop dancing, which includes elements of yoga, attracts mainly women between 25 and 60 who want a fitness routine they will do. Her classes, held at venues including parks and beaches around Chicago, include 20 to 25 minutes of yoga moves, lunges and squats, and hooping for the wrists, hands, shoulders, legs, hips and waists. “The meditative aspect is in the rhythm, the rocking movement that stimulates the heartbeat, the back and forth,”  she said. Dr. Cedric X. Bryant, chief science officer at the American Council on Exercise (ACE), said a 2011 ACE-sponsored study found that hooping could burn up to 600 calories an hour. “We found that just by the nature of movement it did a pretty effective job,” Bryant said. “The only downside is if one had difficulty mastering movement. But larger hoops reduce the learning curve.”  Ibrahim said a hoop, unlike a trapeze, is portable and fun. “Walk up to any kid and they’ll have a go at it,” she said. “Everyone’s happy.”
Example Output: Hoopsters put circus-inspired spin on cardio workout.

Example Input: Several academic laboratories and medical companies are rushing to produce these blood tests, which can quickly identify disease-fighting antibodies in people who already have been infected but may have had mild symptoms or none at all. This is different from the current, sometimes hard-to-come-by diagnostic tests that draw on a nasal swab to confirm active infection. “Ultimately, this (antibody test) might help us figure out who can get the country back to normal,” Florian Krammer, a professor in vaccinology at Mount Sinai’s Icahn School of Medicine, told Reuters. “People who are immune could be the first people to go back to normal life and start everything up again.”  Krammer and his fellow researchers have developed one of the first antibody tests in the United States for COVID-19, the disease caused by the new coronavirus. Krammer said his lab is busy distributing key ingredients for the tests to other organizations and sharing the testing procedure. He is transferring the work to Mount Sinai’s clinical lab this week so it can begin testing patient samples. Antibody tests won’t face the same bureaucratic hurdles diagnostic testing initially did. The U.S. Food and Drug Administration relaxed its rules last month, and body-fluid tests can proceed to market without full agency review and approval. Several private companies have begun selling blood tests for COVID-19 antibodies outside the United States, including California-based Biomerica Inc (BMRA.O) and South Korean test maker Sugentech Inc (253840.KQ). Biomerica said its test sells for less than $10 and the company already has orders from Europe and the Middle East. Chembio Diagnostics Inc CMI.O of New York said it received a $4 million order from Brazil for its COVID-19 antibody test, and it plans a study of the test at several sites in the United States. Such tests are relatively inexpensive and simple, usually using blood from a finger prick. Some can produce results in 10 to 15 minutes. That could make ramping up screening much easier than for diagnostic tests. Many questions remain, including how long immunity lasts to this new virus, how accurate the tests are and how testing would roll out, according to researchers and infectious disease experts. For now, the number of people who have been able to fight off the virus is unknown. If testing goes forward on a wider scale, some public health experts and clinicians say healthcare workers and first responders should take priority. Detecting immunity among doctors, nurses and other healthcare workers could spare them from quarantine and enable them to keep treating the growing surge of coronavirus patients, they say. It could also bolster the ranks of first responders, police officers and other essential workers who have already been infected and have at least some period of protection from the virus, the experts say. “If I ever get the virus and then get over it, I’ll want to get back to the front lines ASAP,” said Dr. Adams Dudley, a pulmonologist and professor at the University of Minnesota School of Medicine. “I would have a period in which I am immune, effectively making me a ‘corona blocker’ who couldn’t pass the disease on.”  Other workers sidelined by lockdowns also could potentially return to their jobs, providing a much-needed boost to the foundering U.S. economy. The number of Americans filing for unemployment benefits has soared, and business activity slumped to a record low this month as the pandemic battered the manufacturing and service sectors. Dr. William Schaffner, a professor of infectious diseases at the Vanderbilt University School of Medicine, said companies, schools, colleges and professional sports teams could all flock to these tests. He also said a broad sample of testing could give a governor or mayor enough confidence to lift certain restrictions on businesses and schools if there is a strong level of immunity. “These tests would be very attractive if they’re cost effective, readily available and easy to do,” he said. Tony Mazzulli, chief microbiologist with Toronto’s Sinai Health system, sounded a note of caution. It is uncertain whether antibodies would be sufficient protection if a person were to be re-exposed to the virus in very large amounts. That could happen in an emergency room or intensive-care unit, for instance. The timing of a return to work and normal life also matters, he said. Some people who have antibodies to the virus could still be contagious, even if their symptoms have eased. Patients begin to make antibodies while they are still sick, Mazzulli said, and they continue to shed the virus for a few days after they have recovered. It would be “a bit premature” to use the tests to make staffing decisions now, Mazzulli said. “The hope is … (antibodies) do confer protection and they can go to work, ride the subways, whatever they do. But there’s no guarantee.”  Meantime, at the Mayo Clinic MAYO.UL in Rochester, Minnesota, researchers are preparing to start a clinical trial in which patients who test positive for COVID-19 would have their blood collected at the time of diagnosis, and again 15 to 20 days after that in the patient’s home. The trial is designed to show when people who have COVID-19 infections “seroconvert” - when antibodies produced by the body begin to show up in blood tests. That information will be useful in determining the best time to conduct the tests. “You don’t want to do it too soon because of the risk of false negatives,” said Elitza Theel, director of Mayo’s Infectious Diseases Serology Laboratory. Mayo also is evaluating the performance of antibody tests from several companies, including two from China. The U.S. Centers for Disease Control and Prevention said it is working on its own version of  antibody tests, but it has not given a timetable. The agency has said extensive research is underway. One challenge for the CDC and other labs is to get enough blood samples from people who have already been infected to verify the antibody results. The agency faced heavy criticism for sending a faulty diagnostic test to state and local labs early in the coronavirus epidemic and then taking weeks to fix it. The federal government is still trying to expand diagnostic testing capacity. The potential for antibody testing arises as U.S. President Donald Trump is considering scaling back “social distancing” and stay-at-home advisories in the weeks ahead. His political allies argue that the toll on the U.S. economy is too severe. About half of Americans have been ordered to shelter in place as many schools and businesses remain shuttered indefinitely. On Tuesday, Trump said: “I would love to have the country opened up and just raring to go by Easter.”  Reopening offices and businesses without fear of triggering more infections, however, has been complicated by the lack of  testing to diagnose COVID-19 cases across much of the country. On Monday, Dr. Deborah Birx, a member of the White House coronavirus task force, said simple, finger-prick antibody tests could play an important role, and she suggested the federal government is not waiting on the CDC’s version. “Some are developed now. We are looking at the ones in Singapore,” Birx said Monday at a White House press briefing. “We are very quality-oriented. We don’t want false positives.”  False positives are erroneous results that, in this case, could lead to a conclusion that someone has immunity when he or she does not. Researchers at the Duke-National University of Singapore Medical School said they quickly developed one antibody test that had about 90% accuracy and later introduced a more sophisticated version that was more reliable, according to a report in the Straits Times of Singapore. Infectious disease experts say immunity against COVID-19 may last for several months and perhaps a year or more based on their studies of other coronaviruses, including Severe Acute Respiratory Syndrome (SARS), which emerged in 2003. But they caution that there is no way to know precisely how long immunity would last with COVID-19, and it may vary person to person. “You are likely to have immunity for several months,” said Dr. Stanley Perlman, a professor of microbiology and immunology at the University of Iowa. “We just don’t know. This is an incredibly important question.”  Perlman said many of the new antibody tests coming on the market now may be highly effective, but researchers want to see  data to back that up. “You want them to be sensitive enough to detect everyone who has had the infection,” Perlman said, “but not so nonspecific that you are picking up other coronaviruses.”   (This story has been refiled to fix Bioamerica Inc RIC)
