A pedestrian bridge suddenly collapsed onto the road below near Florida International University, crushing cars and killing at least six people Thursday.Hours after the bridge collapsed, officials said early Friday that the rescue mission is now a recovery operation.Emergency crews worked overnight in what Miami-Dade Police spokesman Alvaro Zavaleta called a "very slow process" in order to preserve evidence and the safety of possible victims and rescuers, because of unstable conditions at the bridge.At least nine people were transported to hospitals for treatment, authorities said.Witnesses described hearing a loud boom Thursday and moments later, finding victims, including construction workers across the wreckage and people trapped in cars.Senator Marco Rubio, who visited the site Thursday, posted on Twitter: "The cables that suspend the #Miami bridge had loosened & the engineering firm ordered that they be tightened. They were being tightened when it collapsed today." Rubio has been a visiting professor at the university for the past 10 years.The bridge's main span, which weighs 950 ton, had just been installed Saturday over eight lanes, near the university in Miami.  1205

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

A study led by researchers from Washington State University found 24 planets that may be more suitable for life than Earth.According to the study, which was published in the journal Astrobiology, the key points the researchers used to describe the "superhabitable" planets were between 5-8 billion years old, wetter, lightly larger, orbit around a particular star, and slightly warmer than Earth.Researchers also noted that some planets orbit stars that change slowly and have longer life-spans than the sun, which means life could thrive on the 24 planets.More than 4,000 exoplanets, which are planets outside our solar system, were researched before researchers settled on the 24 top contenders.None of the 24 planets checked off all the boxes, researchers said.The study stated that the superhabitable planets are located more than 100 light-years away. 864

A recently published study looks at the potential of asymptomatic spread at grocery stores and the psychological distress of these essential workers.Researchers looked at a grocery store in the Boston area in May. They found 20 percent of the 104 employees tested positive for the coronavirus. This rate was significantly higher than the infection rate in the surrounding community, which was only reporting a positive rate of around 1 percent at the time.More than 75 percent of those who tested positive reported having no symptoms.Those employees who interacted with customers were five times as likely to test positive for COVID-19 compared to employees in other positions."We were definitely surprised to see that there were that many people that were asymptomatic," Dr. Justin Yang, an assistant professor at Boston University School of Medicine and a researcher at Harvard School of Public Health who worked on the study told CNN. "This is definitely very alarming as it means that retail grocery store employees are exposed to customers and sort of serve as a middleman for the virus - like a super spreader almost."The study also looked at feelings of anxiety and depression among the grocery store employees.About 24 percent of all employees reported feeling at least mild anxiety. The data suggests employees who were able to remain socially distant while at work had a lower rate of anxiety; 76 percent of those who reported having no anxiety were able to keep spacing while at work.Whereas 46 percent of those who did report having anxiety were unable to stay socially distant from coworkers or customers while on the job.About 8 percent of employees screened positive for at least mild depression symptoms on a self-reported questionnaire. Those who could not practice social distancing at work and commuted by public transportation were more likely to screen positive for depression.As a conclusion, the team of researchers hopes their findings are a call to action for providing comprehensive employee assistance services to help essential workers in all industries “cope with the psychological distress during the COVID-19 pandemic.”The study was published in the Journal of Occupational and Environmental Medicine. 2241
