Authorities across four countries are trying to learn who sent dozens of email bomb threats Thursday afternoon, causing anxiety and business disruptions but no reported violence.Threats were reported across the United States, Canada, Australia and New Zealand.Universities, courthouses and newspapers received them. It was unknown if the threats were identical.Local police in dozens of cities and counties got involved. So did the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives.Recipients were reported to have received an email saying that there was a hidden bomb that would detonate unless the sender received a bitcoin ransom. It's unclear whether everyone who got a threat Thursday received the same email.An email demanding ,000 via bitcoin was forwarded Thursday to CNN affiliate KOCO-TV in Oklahoma City by a viewer who received it at her business.The message was identical to an email warning posted on social media by the police department in Cedar Rapids, Iowa, and it was similar to descriptions of other threats posted on social media nationwide.The Cedar Rapids Police Department "has found NO CREDIBLE EVIDENCE that these emails are authentic. It appears to be a robo-email that has been sent throughout the area hoping to scam businesses out of money. We have also received information that businesses in surrounding counties may have also received this email," the agency posted.CNN is not disclosing the name of the sender or specifics of the bitcoin account. 1505

As more businesses open up, along with schools and colleges, there are still some hurdles many people need to get over when it comes to fears associated with COVID-19.Fox 17 spoke with Psychologist Dr. Lyndsay Volpe-Bertram from Spectrum Health about these fears."I don't think six or seven months ago any of us thought we'd be still in this current state," Dr. Volpe-Bertram explained, adding that the differences in the way people are handling the precautions is adding another layer of stress. "I think that range of reaction and behavior is also contributing to our overall stress because everybody is kind of taking a different approach to it."To address a balance, Dr. Volpe-Bertram recommends what's called "Ongoing Calculated Risk Assessment", similar to what many call risk vs. reward."We are looking at it as, 'Is this worth it to me?' Is what I'm going to get as a benefit back from having this experience or putting myself out there in some way, is that worth the possible exposure?", asked Dr. Volpe-Bertram.Essentially she recommends we be efficient and choosy in everything we do, even in socializing or explaining."Rather than saying, 'We have to say yes to everything'. Help us identify what are the most important events for us to be attending? Who are the most important people that we want to spend our time with?"Dr. Volpe-Bertram reminds, as the weather turns and flu season fast approaches, not to stress about it, but instead prepare for more mental well-being."It's important for us to start thinking about what our coping strategies are going to be in the Winter and how are we going to keep ourselves busy. Because we don't want people to stay holed-up in their houses, fearful of going out to places. But we want them to move and feel more comfortable in ways that are safe," said Dr. Volpe-Bertram.This story was first reported by Derek Francis at WXMI in Grand Rapids, Michigan. 1916

As parents try to safely entertain their children this summer, many have turned to trampoline parks, bounce houses and bowling alleys that have reopened. But what are the risks of this indoor fun? We asked doctors to weigh in."I think it makes me a little nervous as an infectious disease doctor. A couple reasons. One, it's bringing a lot of people in close proximity and I think we don’t really know what the potential is for transmission in children to other children and adults," said Dr. Beth Thielen, an infectious disease expert with the University of Minnesota.Dr. Thielen says there are still a lot of unknowns when it comes to how easily children can spread the coronavirus to each other. Plus, the effectiveness of masks at an indoor venue like a trampoline park could be minimal. "It's a lot of people in a potentially close space where there’s a lot of aggressive jumping and such, more respiratory secretions. Potentially similar to singing or other activities where you’re producing a lot of droplets and I think that there's real potential to spread in a confined group at this time," Dr. Thielen said.We reached out to dozens of trampoline facilities, bounce house venues and bowling alleys across the country. Only Bowlero Corporation, which also owns AMF and Bowlmor Lanes, responded, directing us to their website listing their new health and safety measures when it comes to protecting guests from COVID-19.The message on their site reads: "As we begin to reopen centers across the country, nothing is more important to us than the health and safety of our guests and staff. In addition to following State and Federal guidelines on COVID-19, we are taking precautions to ensure your visit with us will be safe."Some of their listed new safety measures include temperature checks and masks for their staff. On Launch Family Entertainment's website, which owns Launch Trampoline Park franchises nationwide, the company details their "rigorous STERILE cleanliness certification program." The national certification ensures contactless entry for guests, face masks and gloves for staff, sanitation stations plus reduced capacity.Dr. Thielen responded, "I think it all depends. The devil's in the details in terms of the number and in terms of how restricted [it is]. Is it groups of people who are all spending time together and they're quarantining together in a contained group or is it a mixed population of people from different sites that could be intermixing?" She adds, if she were forced to choose between a trampoline park, bounce house venue or bowling alley, she'd go with bowling alley."I think if people go to a bowling alley and they're wearing masks and staying in their individual space, then there's potential physical separation between people in one lane and another. That's something I would be looking at, can you maintain physical space from other people? It seems harder in a trampoline park but if that could be done safely that would be a positive factor," said Dr. Thielen. Above all, ensuring people are not sick at these indoor venues is key. And it's best to leave high risk populations, such as people with medical concerns or over the age of 60, at home. 3210

As many people started decorating early, it's likely 2020 is a "boom" year for Christmas tree sales. Some even bought a "real" tree for the first time.In July, Bob Schaefer had a feeling it was going to be a big year for Christmas tree sales. The general manager of Oregon-based Noble Mountain Tree Farm says his company looks at the big holidays leading up to the Christmas season to get an idea of what the market will be like.“The next thing we watch is pumpkins - again, off the charts, early,” Schaefer said.Noble Mountain is a large tree producer, and it has been in the Christmas business since 1969. It now sells about half a million trees a year. Schaefer says it developed helicopter harvesting and can have your tree cut and shipped in 24 hours.“This year, we shipped to Dubai, Hong Kong, Canada, Mexico and of course the US,” Schaefer said.Christmas trees are a 10-year crop and once a farm has harvested those trees that are mature and ready, that's it for the tree.“Our sales were off the charts and we did sell out,” Schaefer said. “We’re wholesalers, we don’t sell to individual customers, but our wholesale sales were done by the first of October. Our trees were committed for sale."Schaefer said people started decorating the weekend after Halloween, leading to thriving initial sales.“If it turns out that COVID has people staying home and they have in their hearts the need for a lot of Christmas cheer, then we can provide that with a real tree,” Doug Hundley, spokesman for the National Christmas Tree Association, said.He said if you don't have your tree yet, don't worry. They won't sell out."We’ve never had a shortage. What we have now is a nice balanced, tight market between supply and demand,” Hundley said.It's no easy feat to predict the market, in fact, it's next to impossible, he said.“When we have a boom year like we may be having right now, we kind of suspected it, but we didn’t anticipate it and we can’t produce a real tree overnight,” Hundley said. “So, we have to provide what we have and hope it’ll work out.”He said if lots are empty, it's because the major tree weekends have passed.Ninety percent of people have already gotten their tree this year. Hundley says what's left will suffice for those who still need one. He hopes they all sell. If they don't, they're rendered useless.“The beauty of real trees over fake is we have a highly biodegradable product, it’s grown naturally, part of nature, benefits the environment supports the American economy and when we’re done, we can grind them so easily and chip them into mulch,” Hundley said. “They literally become soil in a couple of years, put back in the ground.”If you are purchasing a natural Christmas tree, experts recommend not adding additives. All your tree needs is plain water at any temperature. 2813

Astrophysicist and author Neil deGrasse Tyson has denied allegations of sexual misconduct made against him by three women.Last month, three women told Patheos, a religion and spirituality website, that Tyson harassed them and made inappropriate sexual advances as early as 1984 and in recent years."Accusations can damage a reputation and a marriage. Sometimes irreversibly. I see myself as loving husband and as a public servant -- a scientist and educator who serves at the will of the public. I am grateful for the support I've received from those who continue to respect and value me and my work," he wrote in a lengthy Facebook post titled "On Being Accused."Tyson disputed or offered a different version of the allegations against him.Katelyn N. Allers, an associate professor of physics and astronomy at Bucknell University in Pennsylvania, told Patheos that Tyson grabbed her arm and reached into her dress while looking at her tattoo of the solar system. She said the incident happened during a party after a gathering of the American Astronomical Society in 2009. 1081
