A recent study appears to show a person’s blood type might indicate whether they will develop severe respiratory failure if they contract COVID-19.The study sequenced genomes of 1,600 COVID-19 patients in Spain and Italy who had been hospitalized with severe respiratory failure and compared the results to DNA sequences of 2,205 healthy subjects.Results appear to show that people with type A blood had a higher chance of developing severe respiratory failure as compared to people with O blood type. The study claims there may be a “protective effect” for blood group O. However this study has not been peer-reviewed yet and the exact kind or extent of “protective effect” is not known.In early June, the site 23andme.com released results from information gathered from 750,000 participants who identified they had COVID-19. The genealogy company said their research suggests a similar effect in people with O blood type. “Individuals with O blood type are between 9-18% percent less likely than individuals with other blood types to have tested positive for COVID-19, according to the data,” a company statement said.They said while there was a significant difference in those with O blood type, there “appeared to be little differences in susceptibility among the other blood types.”However, some are questioning this idea that people with type O blood are protected. Laura Cooling is the director of immunohematology at the University of Michigan. She noted that the idea that having type O blood is protective doesn’t match with current COVID-19 infection rates.Type O blood is usually more prevalent among African Americans, according to the American Red Cross, yet new information from the CDC and states indicate African Americans have experienced disproportionately high COVID-19 infection rates. Cooling says there are many factors to consider.“It’s what your blood type is, relative to the other person who exposed you, relative to all the other genetic and acquired health conditions you have,” she told Chemical and Engineering News on the matter. 2069

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

A Thanksgiving night shooting at a mall in Alabama left two people injured and a gunman dead, authorities said Thursday.The incident at the Riverchase Galleria in Hoover started with a physical altercation between an 18-year-old and the 21-year-old gunman, police said. The confrontation occurred in the mall, near Footaction and JC Penney stores.Police do not know how the confrontation began, but "we do not believe at this point the 18-year-old was armed," Hoover police Capt. Gregg Rector said.The gunman opened fire, shooting the teen twice in the torso, according to police. An officer confronted the gunman as he ran away from the scene and fatally shot him, Rector said.The officer involved has been placed on administrative leave while the Jefferson County Sheriff's Office investigates the incident, police said.A 12-year-old girl was also struck and injured, but it's unclear by whom, Rector said. The two people injured have been hospitalized.The girl had a single gunshot wound and has gone through surgery and "does not have life-threatening injuries," Rector told CNN.Witnesses described hearing gunshots inside the mall, which was open late on Thanksgiving. The scene was chaotic, with customers screaming and staff working to lock down the shopping center, witnesses told CNN affiliate WBRC.The Hoover Police Department said the scene is now secure.Hoover is about 10 miles from Birmingham.Brookfield Properties, which owns the shopping center, said it was devastated by the shooting."We are working closely with the Hoover Police Department and are grateful for their swift action to contain the situation," spokeswoman Lindsay Kahn said."While there is no current danger to our community, the shopping center will remain closed for tonight." 1768

A month ago, a former student roamed the halls of Marjory Stoneman Douglas High, opening fire on terrified students and teachers at the Florida school.The massacre of 17 students and faculty members added to a grim statistic: three of the 10 deadliest mass shootings in modern US history happened within five months of one another. In the four weeks since the Valentine's Day shooting, the survivors have turned into activists on the national stage. Even as they grieve, they've demanded action on gun reform. In between congressional meetings and protests, they've attended memorials and funerals. 606
