A subject coughing in a cyclic incident. Top view of airborne droplet transmission with and without wearing a surgical mask. The top and bottom figures show the results at 4 s and 5 s, respectively. We consider a surgical mask that exhibits an initial efficiency of ～91%. The cover does not prevent the transport of the saliva droplets entirely away from the subject. Many droplets penetrate the mask shield and some saliva droplet disease-carrier particles can travel more than 1.2 m. For visualization, the droplets were scaled by a factor of 600 compared to their actual size. The environmental conditions are zero wind speed, ambient temperature 20 °C, pressure 1 atm, and relative humidity 50%. The mouth temperature is 34 °C, and the face skin temperature is 32 °C. 779

A report prepared for the Senate Intelligence Committee said Russian social media efforts to meddle in the 2016 presidential election included messaging in support of the Green Party 2016 presidential nominee Jill Stein.CNN obtained the report, prepared by New Knowledge, which said the Russian government-linked Internet Research Agency -- a well-known troll farm -- utilized all major social media platforms, and its efforts online included messaging in support of Stein's third party presidential effort.CNN has reached out to Stein for comment on the report.The mentions of Stein online came alongside related and disparate messages noted throughout the report, which said the Internet Research Agency's themes ranged from support for Vermont independent Sen. Bernie Sanders and the Black Lives Matter movement to the Tea Party and gun rights.A summation of the report's findings on "comprehensive anti-Hillary Clinton operations" said while the group's assumed Twitter personas had some pro-Clinton content, "the developed Left-wing Twitter personas were still largely anti-Clinton and expressed pro-Bernie Sanders and pro-Jill Stein sentiments."Likewise, the report said "pro-Bernie Sanders and Jill Stein content" were among the group's go-to themes across other platforms.The report's assertion about support for Stein echoed similar accounts in the past about Russian influence online. An indictment of Russian nationals earlier this year from special counsel Robert Mueller said the online effort included encouraging "minority groups not to vote in the 2016 US presidential election or to vote for a third-party US presidential candidate."Throughout her presidential bid, Stein called for a conciliatory approach with Russia, and she has compared Russian interference in the 2016 election with US efforts around the globe.Earlier this year, Stein told CNN she objected to turning over some documents to the Senate Intelligence Committee. She said at the time the requests were overly broad and unjustified."Legitimate concerns about interference in our election should not be twisted into a campaign of censorship, war-mongering and political intimidation against opposition to the bipartisan establishment," Stein said.CNN previously identified at least one occasion when the Russian group targeted Green Party activists.In the days after the shooting of Philando Castile in July 2016, the Russian group used a fake Black Lives Matter page called "Don't Shoot Us" in an attempt to organize a protest against the police.Brandon Long, the state party chairman of the Green Party of Minnesota, remembers hearing about the planned "Don't Shoot Us 'event. He told CNN, "We frequently support Black Lives Matter protests and demonstrations and we know pretty much all the organizers in town and that page wasn't recognized by anyone." CNN later reported "Don't Shoot Us" was run from Russia. 2905

A protest has erupted at the U.S-Mexico border. Watch streaming video in the player below:SAN DIEGO (KGTV) -- The journey has come to an end for hundreds of migrants seeking asylum in the U.S.A large caravan arrived in Tijuana within the last week and have waited until Sunday to cross the border into San Diego.Late Sunday afternoon, members of the caravan plan to turn themselves in to customs agents seeking asylum.Most of the roughly 400 migrants in the caravan are women and children who have been staying in shelters, seeking legal counsel before trying to cross the border.Border patrol agents released a statement Saturday saying several groups associated with the caravan have been illegally climbing a scrap metal border fence.The statement warned anyone with the caravan to “think before you act.” The Secretary of Homeland Security also said in a statement earlier this week that anyone seeking asylum “may be detained while their claims are adjudicated.”Protesters say the group is taking advantage of U.S. immigration laws. A group called San Diegans for Secure Borders plans to protest at Friendship Park.They say the migrants are unwelcome and that their claims for asylum are false. 1207
