As the world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855

Ashley Meadows has a tough job. As the gallery guide coordinator at the Hirshhorn Museum in Washington DC, she tries to get people to talk about modern and contemporary art.Consider the look of panic on people's faces when they're urged to express an opinion about a Jackson Pollock painting."It's hard to start a conversation with a stranger," Meadows, 33, said.But these days she has an ally in her efforts: a small humanoid robot named Pepper.The human-shaped robot stands four feet tall on one tapered leg, a shiny white body and big puppy dog-like eyes.Tucked into the curves of the Smithsonian's brutalist modern art temple, Meadows watches Pepper entertain guests. It dips at the waist, plays music and offers to take selfies -- the most popular of Pepper's tricks.This particular Pepper is one of a 25 strong army of robots at The Hirshhorn Museum and three other Smithsonians in the city, including The African Museum of Art, the African American Museum of History and Culture and the Smithsonian Castle.The robots made their debut this week.Pepper was donated by its manufacturer, the Japanese company Softbank Robotics.Pepper, first unveiled in 2014 in Japan, can be programmed for different use cases, whether it's at restaurant chain Pizza Hut, airports or now museums.But Pepper has limited functionality. It won't go off script but can tell guests a story, give them more information about a piece of art or "do something fun," like play music and dance with guests.Rachel Goslins, Smithsonian's director for the Arts and Industries Building, hopes Pepper's presence will encourage people to be more engaged as they walk through the galleries."I'm the mother of the robots," Goslins said.She decides which museums they're stationed at and and what they do. They're typically positioned in spots where she hopes for increased traffic or for people to linger longer."They're attracted to the robots like a magnet," Golsins said of its success so far.Pepper has already doubled foot traffic to a frequently missed section of the Museum of African American History and Culture -- the second floor educational gallery.But Pepper isn't perfect. Some visitors complained the robot couldn't speak or understand any language besides English. Others repeatedly asked Pepper questions it couldn't answer.Each Pepper robot has bodyguards to make sure the system is properly functioning, its software is updated to protect against hacking and that people don't harm the machines themselves.After entertaining visitors for most of the morning, Meadows powered down Pepper for a rest. The robot's eyes went dark and its white form slumped over like a puppet released from its strings."Say bye, Pepper!" said Meadows, wheeling the robot off the floor. 2758

At least 100,000 small businesses have had to close permanently in the last nine months, according to data gathered by Yelp. Millions more have dealt with temporary closures and major losses in revenue.Now, many remaining small businesses are reliant on a strong holiday shopping season, and there’s finally some good news for these business owners and their employees.For example, at the Boston area small business called Boing Toy Shop, owner Kim Mitchell has been working overtime for the pasting nine months. She has had drastically change her business model.“In certain ways, I feel like although I am in the same physical footprint, I am almost running a completely different business,” said Mitchell.Since the start of the pandemic, Mitchell has had to shift more than half of her business online and added curbside pickup to keep her toy shop out of the red.“In certain ways, I almost feel like we are part store-front, part warehouse,” she added.However, in many ways, she still feels lucky to have some form of her business when so many other small businesses have had to close.“One of the first ones, unfortunately, was the store right across the street from me,” said Mitchell.The boutique clothing store across the street from Boing is just one of an estimated 27 percent of small businesses that have closed across the country, according to a Harvard University Project. And without a strong holiday season, even more permanent closures are feared.So, how has the holiday shopping season been so far for small businesses?“I had by far my most successful small business Saturday, which I did turn into small business weekend. I sort of stretched it,” said Mitchell. “There definitely is a sense, and I have a sense from my customers, that they are making a conscious decision to support their local businesses.”From Boing to stores around the country, consumers opened their wallets more than ever on Small Business Saturday. According to Adobe Analytics data, they spent a record .7 billion just online.“Smaller retailers have seen a 501 percent increase in revenue through the holiday season so far relative to a typical day in October,” said John Copeland with Adobe Analytics,” “From a percentage increase, small and medium-sized businesses are outperforming in terms of percentage gains.”From Adobe’s holiday shopping data to the Boston toy shops’ experience, it is clear consumers are conscious of how much mom and pop businesses are struggling and how important it is to help them and the workers they employ."It is really nice that, especially in a time like this, where we really need the community’s support in return. They are coming out and realizing that ‘hey, these small businesses have been there for us for a long time; now it is time to get their back,’” added Mitchell. 2811

ATLANTA (AP) — Former President Jimmy Carter marks his 96th birthday Thursday, the latest milestone for the longest lived of the 44 men to hold the highest American office.Carter planned to celebrate at his home in Plains, Georgia, with his wife of 74 years, Rosalynn Carter, according to a spokeswoman for the Carter Center in Atlanta.The 39th president, in office from 1977-81, has largely receded from the public eye amid the coronavirus pandemic and his own health challenges due to a series of falls in 2019. He previously survived a dire cancer diagnosis in 2015.Yet Carter remains a quiet force still active in both politics at home and, through his post-presidential center, in public health and human rights advocacy around the world. 751

As President Donald Trump and Republicans attempt to reverse the results of last week’s presidential election in Pennsylvania, a significant case often cited by Trump’s supporters has lost steam.The House Oversight Committee, led by Democratic Congresswoman Carolyn Maloney, announced that Richard Hopkins has “recanted” his claim of election fraud in Erie County, Pennsylvania. Hopkins had previously accused fellow USPS employees of changing the date of ballots submitted after the election. 501
