While many businesses shut down temporarily due to COVID-19, zoos and aquariums couldn’t fully close because animals still need to be taken care of.However, with little to no visitors during what’s normally the busiest time of the year, some are facing tough times and getting creative.“It’s a lot of work,” said Patty Wallace, an Animal Keeper at the Cheyenne Mountain Zoo.“We feed all of them about three times a day, about 40 pounds each of grass hay, about six pounds of grain per hippo, and also some fruits and vegetables for training and nourishment. So they get lots of variety,” Wallace explained. That’s just the hippos, which are part of a new exhibit the zoo opened during the shutdown.“Opening a brand new exhibit is normally hard enough,” said Bob Chastain, the President and CEO of the zoo.With large groups and traditional presentations considered unsafe, the zoo pivoted. “Now, what we do instead is we’re grabbing random people and taking them back behind the scenes, letting them help us with the everyday things we’re doing,” Chastain said.Letting kids help feed the hippos and other animals, up close and personal.“We are trying to adjust and we would like to share our hippos,” Wallace said. “But because we don’t want crowds, we do it in small bursts.”Back in spring, zoos and aquariums were told to close.“All of them have had a period of two to four months of closure. Some are still closed,” said Dan Ashe, President and CEO of the Association of Zoos and Aquariums. AZA is a nonprofit that represents over 240 of these businesses.“When they’re closed they’re not really closed, because they have to continue caring for the animals,” Ashe said. That’s what makes zoos and aquariums unique.“The essential ingredient in success is a guest,” he said. Even with no guests, the work doesn’t stop, which has put some in financial distress. “We have had some that have been on the verge of closure.”Ashe said about 20% of its members are in a weak financial position, so zoos got creative to keep guests interested. “The San Antonio Zoo started with the idea of a drive-thru zoo,” Ashe said.At Cheyenne Mountain Zoo, they made use of social media. “Our social media team, like many around the country, really ramped up,” Chastain said.Now as they begin to reopen their gates, they face a whole new set of challenges. “Almost every zoo in the country had to revamp and figure out how to do timed tickets, because it was one of the major requirements,” Chastain said.Timed ticketing, one way traffic, cashless exchange -- these were all concepts zoos and aquariums had to adapt to.“All over the zoo there are marks that help people stay away from each other,” Chastain said.Even with sold out tickets, the crowds are nothing like they used to be. And many fundraising events had to be canceled or postponed with new capacity limits.“Our guess is for the next 12 months, we won’t have those large crowds,” he said.But families continue to come to see the giraffes, look at the penguins, or feed Zambezi and Kasai, the hippos.“It’s been a challenge, but a lot of fun,” Wallace said. 3105

While travel advice abounds for the best times to buy the most affordable holiday plane tickets, flying during some of the year's busiest travel periods generally isn't cheap.In this era of packed airplanes, smaller seats and fees for extra leg room, what airline is going to offer inexpensive fares around Thanksgiving, Hanukkah, Christmas and New Year's? Common business sense dictates that high prices will follow high demand.What are procrastinating travelers to do besides drive or take the train to get to their destinations? CNN checked with airfare experts for some general advice and ways to dull the price pain: 644

With coronavirus cases spreading among White House staff, the Commission on Presidential Debates confirmed Monday evening that a Plexiglas partition will be used on stage during Wednesday’s vice presidential debate.Peter Eyre, a senior adviser to the debate commission, said that the candidates will be seated 12 feet, 3 inches apart, and that there will be no handshakes allowed on stage between the candidates or moderator.Eyre added that the candidates, Vice President Mike Pence and Senator Kamala Harris, will be tested for the coronavirus before the debate. For the previous debate, the candidates were responsible for their own coronavirus testing.Only the candidates and moderator will be allowed to not wear a mask during the debate, also a change from last week’s presidential debate. During last week’s presidential debate, members of President Donald Trump’s entourage took off their masks during the debate.Eyre said that a small number of ticketed guests will be allowed into the debate hall in Utah.“If anyone does not wear a mask, they will be escorted out,” Eyre confirmed.Plexiglas was also used in last Saturday's US Senate debate between Republican Lindsey Graham and Democrat Jamie Garrison. A Pence aide said a divider was "not needed."“If she wants it, she’s more than welcome to surround herself with plexiglass if that makes her feel more comfortable,” Marc Short, the vice president’s chief of staff, told the Washington Post. “It’s not needed.” 1479

With a coronavirus vaccine still months off, companies are rushing to test what may be the next best thing: drugs that deliver antibodies to fight the virus right away, without having to train the immune system to make them.Antibodies are proteins the body makes when an infection occurs; they attach to a virus and help it be eliminated. Vaccines work by tricking the body into thinking there’s an infection so it makes antibodies and remembers how to do that if the real bug turns up.But it can take a month or two after vaccination or infection for the most effective antibodies to form. The experimental drugs shortcut that process by giving concentrated versions of specific ones that worked best against the coronavirus in lab and animal tests.“A vaccine takes time to work, to force the development of antibodies. But when you give an antibody, you get immediate protection,” said University of North Carolina virologist Dr. Myron Cohen. “If we can generate them in large concentrations, in big vats in an antibody factory ... we can kind of bypass the immune system.”These drugs are believed to last for a month or more and could give quick, temporary immunity to people at high risk of infection, such as health workers and housemates of someone with COVID-19. If they proved effective and if a vaccine doesn’t materialize or protect as hoped, the drugs might eventually be considered for wider use, perhaps for teachers or other groups.They’re also being tested as treatments, to help the immune system and prevent severe symptoms or death.“The hope there is to target people who are in the first week of their illness and that we can treat them with the antibody and prevent them from getting sick,” said Dr. Marshall Lyon, an infectious disease specialist helping to test one such drug at Emory University in Atlanta.Having such a tool “would be a really momentous thing in our fight against COVID,” Cohen said.Vaccines are seen as a key to controlling the virus, which has been confirmed to have infected more than 20 million people worldwide and killed more than 738,000. Several companies are racing to develop vaccines, but the results of the large final tests needed to evaluate them are months away.The antibody drugs are “very promising” and, in contrast, could be available “fairly soon,” said Dr. Janet Woodcock, a U.S. Food and Drug Administration official who is leading government efforts to speed COVID-19 therapies. Key studies are underway and some answers should come by early fall.One company, Eli Lilly, has already started manufacturing its antibody drug, betting that studies now underway will give positive results.“Our goal is to get something out as soon as possible” and to have hundreds of thousands of doses ready by fall, said Lilly’s chief scientific officer, Dr. Daniel Skovronsky.Another company that developed an antibody drug cocktail against Ebola — Regeneron Pharmaceuticals Inc. — now is testing one for coronavirus.“The success with our Ebola program gives us some confidence that we can potentially do this again,” said Christos Kyratsous, a Regeneron microbiologist who helped lead that work.Regeneron’s drug uses two antibodies to enhance chances the drug will work even if the virus evolves to evade action by one.Lilly is testing two different, single-antibody drugs — one with the Canadian company AbCellera and another with a Chinese company, Junshi Biosciences. In July, Junshi said no safety concerns emerged in 40 healthy people who tried it and that larger studies were getting underway.Others working on antibody drugs include Amgen and Adaptive Biotechnologies. The Singapore biotech company Tychan Pte Ltd. also is testing an antibody drug and has similar products in development for Zika virus and yellow fever.“I’m cautiously optimistic” about the drugs, said the nation’s top infectious diseases expert, Dr. Anthony Fauci. “I’m heartened by the experience that we had with Ebola,” where the drugs proved effective.What could go wrong?— The antibodies may not reach all of the places in the body where they need to act, such as deep in the lungs. All the antibody drugs are given through an IV and must make their way through the bloodstream to wherever they’re needed.— The virus might mutate to avoid the antibody — the reason Regeneron is testing a two-antibody combo that binds to the virus in different places to help prevent its escape.Skovronsky said Lilly stuck with one antibody because manufacturing capacity would essentially be cut in half to make two, and “you will have less doses available.” If a single antibody works, “we can treat twice as many people,” he said.— The antibodies might not last long enough. If they fade within a month, it’s still OK for treatment since COVID-19 illness usually resolves in that time. But for prevention, it may not be practical to give infusions more often than every month or two.A San Francisco company, Vir Biotechnology Inc., says it has engineered antibodies to last longer than they usually do to avoid this problem. GlaxoSmithKline has invested 0 million in Vir to test them.Giving a higher dose also may help. If half of antibodies disappear after a month, “if you give twice as much, you will have two months’ protection,” Lilly’s Skovronsky said.— The big fear: Antibodies may do the opposite of what’s hoped and actually enhance the virus’s ability to get into cells or stimulate the immune system in a way that makes people sicker. It’s a theoretical concern that hasn’t been seen in testing so far, but large, definitive experiments are needed to prove safety.“As best as we can tell, the antibodies are helpful,” Lyon said.___Marilynn Marchione can be followed on Twitter: @MMarchioneAP___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

West Virginia public school teachers will strike for an eighth day Monday because the state legislature didn't meet their demand for higher pay and better benefits over the weekend.All 55 counties announced school closures for Monday. About 20,000 teachers walked out February 22, keeping almost 277,000 students out of class.Union leaders say the teachers won't return to work until they get a 5% raise.The pay raise remains in legislative limbo. At the state capitol in Charleston, a conference committee has been appointed?to resolve the differences between the state Senate and House.It's not known when the committee will meet, so it's possible the strike could stretch out for days.The waiting frustrates parents, students and union leaders, who've marched and crowded the state capitol for legislative hearings."We're playing with people's emotions, their livelihoods and it directly affects our students," said Christine Campbell of the American Federation of Teachers. "This is unprecedented. It's confusing and I think (teachers are) disheartened by the process."West Virginia public teachers earn?an average salary of about ,000, making them among the lowest paid educators in the United States.Gov. Jim Justice and the union leaders agreed earlier in the week that teachers and service personnel would receive a 5% pay raise.However, that raise must be passed as a law, since West Virginia is not a collective bargaining state.The bill quickly passed in the House Wednesday, but Senate lawmakers expressed concern about how the state will fund the raise.Democrats say new revenue projections show the money is there and that a difference of one percent would amount to million.On Saturday, after hours of passionate argument and discussion by lawmakers, the state Senate passed a version of the bill that provides a 4% raise.The House voted not to adopt the 4% version of the bill. With no agreement between the chambers, the conference committee was created.Three members from the House and three from the Senate -- two Republicans and one Democrat -- were selected. The group will have three days to come to a decision about the bill.A brief period of confusion occurred Saturday night after the Senate believed it had voted for the 4% raise. But a House version of the bill, which favored the higher pay raise, had somehow been entered into the Senate voting system and was approved by unsuspecting Senate members. When the error was discovered, the Senate corrected the mistake and re-voted for the lower pay raise.Elizabeth Yost, a teacher from Mercer County, said she was not discouraged by the votes in the legislature."When the events unfolded from there, it was evident we have a representative government in the Senate that abused power last night," she said. "Today, my determination, and that of my colleagues, is stronger." 2868
