GENEVA (AP) — Russia has been banned from using its name, flag and anthem at the next two Olympics or at any world championships for the next two years. The Court of Arbitration for Sport’s ruling also blocks Russia from bidding to host major sporting events for two years. Russian athletes and teams will still be allowed to compete at next year’s Tokyo Olympics and the 2022 Winter Games in Beijing if they are not implicated in doping or covering up positive tests. The punishments are less than the four-year ban the World Anti-Doping Agency had proposed.One small win for Russia is the proposed team name at major events. The name “Russia” can be retained on uniforms if the words “Neutral Athlete” or “Neutral Team” have equal prominence, the court said.Still, the court’s three judges imposed the most severe penalties on Russia since allegations of state-backed doping and cover-ups emerged after the 2014 Sochi Olympics.The case centered on accusations that Russian state authorities tampered with a database from the Moscow testing laboratory before handing it over to WADA investigators last year. It contained likely evidence to prosecute long-standing doping violations. 1191

Health officials agree coronavirus cases are going to increase this winter as Americans head indoors to stay warm and closed windows will lead to less ventilation.But what about the dry air inside and outside this time of year, could a humidifier help slow the spread of coronavirus? That is still being debated.A study released this month seems to suggest increasing humidity plays a role in decreasing cases of coronavirus. The study, which has not been peer-reviewed yet, was shared on medRxiv.This study was based on the premise that previous studies have shown that falling humidity is tied to increased transmission rates of other respiratory diseases, like the flu. Researchers looked at more than 3,000 counties around the country and their humidity levels between March and September 2020.The team says they found increasing humidity levels had a negative impact on new cases of COVID-19 in most regions. In two of the regions that showed the highest effect, a 1 g/m3 increase in absolute humidity resulted in a 0.21 and 0.15 decrease in COVID-19 cases.However, there are also studies that show the humidity level had little to no effect on the spread of COVID-19.A study released in early November found the weather had “virtually no impact” on the spread. Instead, they said human behavior changes during weather fluctuations, outside during warmer weather and heading indoor during cold weather, had a large impact.What health and science experts seem to agree on is that the air does get drier in the winter from both the cold air outside and heated air inside. And that without proper ventilation, any coronavirus droplets in a space could linger longer and become more concentrated.This dry air can also cause nasal passages to dry out, which means noses could have less protective mucus. Some doctors have said whether or not the science completely proves humid air can help slow the spread of coronavirus, having more humidity in the air can make this winter more comfortable and noses more able to protect against all virus. 2051

HONG KONG — Hong Kong Disneyland Park is closing temporarily following the city’s decision to ban public gatherings of more than four people because of the coronavirus pandemic. Disney officials posted on the resort’s website that the Hong Kong park was closing Wednesday until further notice. The resort’s hotels will remain open with adjusted levels of service. Hong Kong’s leader, Carrie Lam, announced new coronavirus-related restrictions Monday and she urged the private sector to put in place work-from-home arrangements for employees. The Hong Kong park and Shanghai Disneyland closed in January because of the virus. Shanghai Disneyland reopened in May, as did the Hong Kong park last month. 707
