A van slammed into a crowd Saturday in an apparently deliberate act in the German city of Muenster, killing two people and leaving 20 others injured, officials said.The driver also shot and killed himself, a police spokeswoman said. The driver was a German citizen, said Herbert Reul, state minister for internal affairs in North Rhine-Westphalia state.Authorities are treating the incident as an attack. There is no known connection to radical Islam but investigators are still looking into the driver's background, Reul said.Police earlier said there were three deaths. Reul clarified later Saturday that the total included the attacker.Muenster police spokesman Andreas Bode said law enforcement is looking into witness reports that some people fled the attacker's van after the attack. He also said there was a suspicious object in the vehicle that was under investigation.Bode said the motive of the driver is unknown.The attack happened in the old part of the western German city, an area popular on weekends. It was a warm sunny afternoon, one of the first nice days of spring, and many people were out in the area with its narrow streets, Bild editor Julian Reichelt told CNN.German Chancellor Angela Merkel said she is "deeply shocked by the terrible events in Muenster."In a statement tweeted by German government spokeswoman Ulrike Demmer, Merkel said "everything is now being done to clarify the act and support the victims and their families."The driver drove a vehicle into a restaurant's open terrace around 3:30 p.m. local time, according to police spokeswoman Vanessa Arlt.Arlt said the old city remains closed, and police have asked people to avoid the city center.Muenster, with about 300,000 people, is home to numerous universities and has a student population of about 58,000, the city government says. The city calls itself the cycling capital of Germany and says about 100,000 residents use a bike daily."With dismay, I learned of the terrible incident in Muenster," Interior Minister Horst Seehofer said in a statement, adding, "Police in Muenster and throughout (the state of North Rhine-Westphalia) are now working hard to investigate the matter."Federal authorities are in close contact with local officials, Seehofer said.The White House sent condolences in a statement from press secretary Sarah Sanders."Our thoughts and prayers go out to the families of those killed and we wish a full recovery to those injured. While the German authorities have not yet announced a motive for this cowardly attack on innocent people, we condemn it regardless, and pledge any support from the United States government that Germany may need."Saturday's crash occurred on the one-year anniversary of a similar attack in Stockholm, Sweden, when a stolen beer truck struck pedestrians, killing five people. 2826

A recent study published Tuesday in the journal JAMA Internal Medicine found that most Americans are still susceptible to COVID-19.According to the study, researchers studied the blood samples of 177,919 Americans across the nation, D.C., and Puerto Rico between July 27 and Sept. 24. They found that fewer than 10% of the people had detectable COVID antibodies."In this U.S. nationwide seroprevalence cross-sectional study, we found that as of September 2020, most persons in the US did not have detectable SARS-CoV-2 antibodies, and seroprevalence estimates varied widely by jurisdiction," the authors concluded. "Continued biweekly testing of sera collected by commercial laboratories will allow for assessment of the changing epidemiology of SARS-CoV-2 in the U.S. in the coming months. Our results reinforce the need for continued public health preventive measures, including the use of face masks and social distancing, to limit the spread of SARS-CoV-2 in the U.S."Researchers noted that Seroprevalence varied between metropolitan/nonmetropolitan areas and across regions, with estimates as high as 23% in the northeast, 13% in the south, and forecasts in the midwest and west were less than 10%.The researchers also found that Seroprevalence was often lowest in older age groups. 1295

A retired police officer who was falsely accused by many Twitter users of accosting three young adults on a Maryland bicycle trail says he was saddened and scared by the barrage of hate directed against him.John Damskey, a Montgomery County police officer for nearly 30 years, was one of at least two men whose names, photos and personal information were posted by internet vigilantes before police on Friday arrested and charged another man, 60-year-old Anthony Brennan III, with assaulting three people posting flyers protesting the death of George Floyd.Millions of Twitter users have viewed a video of the encounter. Many falsely blamed Damskey, who says the experience has been surreal and terrifying.In a widely-shared video, the man, allegedly Brennan, attacked three young adults last week who were posting flyers in support of the Black Lives Matter movement. The video showed a man arguing and grabbing the flyers from one of the victims. The man then pushed his bicycle toward one of the victims who was filming the encounter.“I’ve got a wife who is in tears. My mom is scared to death,” he told The Associated Press on Monday. “It’s sad. It’s scary. It’s something that I don’t ever want to go through again.” 1229

A subject coughing in a cyclic incident. A qualitative examination of airborne droplet transmission with and without wearing a surgical mask. The top and bottom figures show the results at 2 s and 3 s, respectively. Wearing a surgical mask that exhibits an initial efficiency of ～91%. This cannot prevent the transport of the saliva droplets 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. 775
