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

ATLANTA — Georgia's legislature on Tuesday passed hate crimes legislation deemed essential by state leaders, sending the measure to Gov. Brian Kemp's desk.Georgia is currently one of four states in the U.S. without hate crime laws.The price Republicans exacted for moving that legislation forward was the simultaneous passage of a bill that would mandate penalties for crimes targeting police and other first responders.The action comes after Senate Republicans had added police as a protected class to the hate crimes legislation last week, but then moved those protections to a separate bill in a deal between the parties.Kemp's office said in a statement that he'd sign the hate crimes bill, pending a legal review.The bill's passage comes amid weeks-long protests against systemic racism throughout the country. The protests were sparked by the death of George Floyd, who died in police custody in Minneapolis after bystander video showed an officer kneeling on his neck for more than eight minutes.The passage also comes weeks after three arrests were made in connection with the shooting death of Ahmaud Arbery. The 25-year-old Arbery was killed in Burnswick, Georgia in February, and his case changed jurisdictions several times due to one of the suspect's connections with the local District Attorney's office. It wasn't until days after a video of the altercation leaked to the public in May that two of the men, Gregory and Travis McMichael, were arrested and charged with murder. A third man, William "Roddy" Bryan, was also charged with murder a few weeks later. 1582

As school districts across the country prepare to send kids back to school in-person, many bus drivers are voicing concerns about the potential for COVID-19 to spread on school buses, where oftentimes social distancing is nearly impossible.For the better part of 32 years, Cheryl Merritt has driven a school bus in Hanover, Massachusetts. She has driven in every kind of weather condition imaginable, but this is the first year she’ll be driving a bus during a pandemic.“I just want all the kids on the bus to stay safe and the drivers to stay safe. If we have a driver who gets sick, they’re going to be out for at least 14 days,” she lamented, as she turned her bus onto a side street in a residential New England town.Merritt’s concerns are shared by school bus drivers and districts across the country. Many school bus drivers have retired from other professions, meaning their age makes them more susceptible to catching the virus.“I don’t want this, I don’t. I’m not ready to die,” the 61-year-old Merritt said.School buses are presenting a particularly difficult challenge as districts try to send kids back to the classroom. When fully loaded with kids, most school buses fit about 77 students. Cramming students into a bus though would be a perfect place for COVID-19 to spread, so many states are advising bus companies to have only one student per bench. But taking some bus capacity down to about 12 kids means school districts would need to run double or triple the number of trips each day just to pick every child up.Transportation experts say adding more buses would be nearly impossible given a nationwide bus driver shortage, which existed long before the outbreak.“It doesn’t matter what you’re gonna do with kids once you get them to school, you have to get them there first,” explained David Strong, who works with the School Transportation Association of Massachusetts.Strong’s other concern is that kids won’t adhere to social distancing guidelines or mask-wearing requirements once they get onto a bus.“There’s almost no way to realistically social distance on a bus,” he added.To address concerns about the spread of COVID, many school districts are mandating that school buses keep their windows open year-round to help with the flow of air. Some districts are also adding bus monitors to ensure kids, especially elementary school students, are following new guidelines.As for Merritt, she sees herself and other bus drivers as the first line of defense when it comes to keeping COVID-19 out of the classroom.“When you stop to pick up a child look at them, make sure they don’t look sickly or they’re coughing,” she said. 2655

AVENAL, Calif. (AP) — Authorities say an inmate at a central California prison died of complications from the coronavirus Saturday, becoming the state’s 79th person to have a fatal case of COVID-19 while they were incarcerated. The Avenal State Prison inmate died at a hospital. The prisoner’s name was not released. There have been 15,872 confirmed cases of the coronavirus in the state prison system. Advocates say jails and prisons nationwide are prime locations for the virus to spread between inmates and staff. Officials have released hundreds of inmates to decrease jail and prison populations across the country during the pandemic. 648

At Tivoli Brewing Company, canning beer has gone from celebratory to an almost sobering experience.“This sucks,” said Ethan Tsai, Tivoli brewery director.Tsai says Tivoli and other breweries across the country are suffering from an aluminum can shortage.“We don’t have enough cans, we’re not going to be able to sell enough beer,” he said. “This is going to be a financial pinch to a whole lot of people.”On a normal week, Tivoli would turn out almost 400 cases of beer. During the last few of weeks, however, they’re struggling to get out 100.“Sales is going to suffer,” Tsai said. “And if sales suffer, then our ability to survive is going to be jeopardized.”Experts say there are several reasons for this shortage in cans. More people are stocking up on beer in stores and taking it home during the COVID crisis and less customers are going out to bars and restaurants.Whatever the case, production of cans isn’t keeping up with the demand.“For the year 2020,” Tsai said, “Ball (Corporation) is estimating approximately 10 billion, that’s billion with a “B”, aluminum can shortage."Ball Corporation is one of the world’s leading aluminum can providers. It’s responding to the recent surge in demand for cans by expanding its operations and building two news production plants which they say should be completed by 2021.“It might mean that some brewers get less revenue and have to make more difficult choices,” said Bart Watson, chief economist with the Brewers Association, an organization representing thousands of craft breweries across the country.He says cans make up a majority of craft beer packaged sales and that this shortage of could cost companies money and employees their jobs.“It’s tough to see the small brewers, who put so much sweat equity into their businesses, be brought down by really something that not their fault,” Watson said. “First the pandemic and now these additional challenges like a shortage.”Back at the brewery, Tsai is trying to figure out how to logistically juggle this shortage of cans during a pandemic to make sure his staff still have jobs and that this brewery survives.“We are all in this together,” he said. “None of us benefit from just taprooms suddenly disappearing.” 2226
