A viral video of a police officer hitting a 14-year-old girl during an arrest has caused outrage in a Florida community.The video -- posted to Instagram on Friday -- shows a girl being held down by two officers, one man and one woman. The male officer hits the girl in the side twice as he holds her shorts."Why you hitting her?" someone in the video yells. "She can't do that, her hands underneath her, the f*** you hitting her for?"The police department in Coral Springs, about 29 miles northeast of Fort Lauderdale, said in a statement on Facebook on Friday that the video does not show the entire incident that led to the arrest. 641

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 public school administrator in Nashville has resigned following the disclosure of a secret recording where he plotted to bypass filters designed to protect children from exposure to lead in their water.Metro Nashville Public Schools (MNPS) executive director of facilities Dennis Neal, resigned Friday, according to MNPS communications director Olivia Brown. Neal had been placed on administrative leave while the district investigated.Neal's resignation came less than a week after Scripps station WTVF in Nashville?uncovered the recording from inside a meeting of schools maintenance employees.Recording Reveals Plan To 'Bypass' Lead FilterFor the past nine months, WVTF has exposed data kept secret by the district showing high lead levels in some Metro schools. Lead is a toxic metal that can cause learning and behavioral problems in children.In response, a number of schools installed special fountains that were supposed to filter out the lead. Some of them were purchased by parents themselves.But the recording revealed Neal's plan to dismantle those efforts.Listen to the audio below:"People keep wanting these bottle fillers, but they are adamant about them being filtered," Neal told his employees. "I'm saying we cannot support it.From the beginning, Neal downplayed the threat posed by lead in the schools' drinking water  -- despite results showing levels well above what pediatricians say is safe. Audio Sparks Outrage, Mayor Calls For AnswerStill, some 30 schools installed hydration stations specifically designed to filter out the lead — some of them purchased by the parents themselves.On the recording, Neal revealed: "I did ask Troy if he would have one of his guys go through the exercise of bypassing the filter just to see how that works."But those fountains are equipped with lights that show when the filters are working and when they need to be replaced.So Neal's team came up with a solution for that, too."We've got to figure out what we are going to do with these hundred, or 97, filtered ones that we have out there," Neal told his subordinates. An unidentified woman interrupted, "Bust the light out.""Huh, do what?" Neal asked."Take the light bulb out," she answered."Well, that's one thing," Neal agreed. "But we need to also probably, if we can, bypass the filter."Neal's concern was money.MNPS Spokesperson Questions Need For Filters"If we were to replace a filter, you're talking — I don't know if any of y'all have bought them  — it's something like 70 or 80 bucks," Neal said.An unidentified man responded, "."Neal said, "That's almost ,000 a year just for filters, OK, on what we have now."After disclosure of the record, Schools Director Dr. Shawn Joseph condemned the comments captured on the recording."As a parent of two Metro Schools children and as the Director of Schools, the idea that a supervisor would discuss a workaround on our water fountains knowing that this is a huge concern for many families is upsetting and unacceptable," Joseph said.Nashville Mayor David Briley also said that "obviously, if the report is true, that person shouldn't  be responsible for protecting our children from lead in their drinking water."  3312

A parrot in the United Kingdom used his owner’s Alexa to shop online while his owner was away, according to the Daily Mail. According to the paper, the parrot’s owner, Marion Wischnewski, decided to foster him after volunteering at a sanctuary. The bird was placed at the sanctuary because staff feared his use of swear words would upset people. After taking the bird home, Wischnewski, said she started noticing that the bird was purchasing things like watermelon, raisins, ice cream, a light bulb and even a kite while she was away. Wischnewski says, after catching the shopaholic, she now checks her online shopping list when she comes home to cancel any items purchased by the parrot. 698
