About 15% of U.S. households with school-aged children don’t have a high-speed internet connection, according to a study done by Pew Research.In Detroit, that number is much higher. As school and work continue online, the digital divide is becoming more obvious in neighborhoods without high-speed internet.“Even before the pandemic, digital access was a huge challenge in the city of Detroit,” Raquel Castaneda-Lopez, a City Councilwoman in Detroit, said.“In Southwest Detroit, some people might not have internet,” said Anderson Walworth, the Chief Network Engineer for the Equitable Internet Initiative. Walworth led a team on to the roof of a building in Southwest Detroit to install internet infrastructure. It will help provide public internet access for everyone in the surrounding community.“A hotspot install at the Michigan Welcome Center in Southwest Detroit,” Walworth explained.Why is this necessary, especially on a 95 degree day in the middle of summer?“It's about 28% of folks that don't have internet access at all in the city of Detroit,” Castaneda-Lipez said. “We can't just assume people have access to the internet, or they have the resources to pay the monthly subscription to buy it from Comcast or wherever.”Because of COVID-19, many school-aged children have been forced to work and learn online, and that could continue for part of the next school year.“The coronavirus, most everybody’s working from home. School is from home,” said Norma Heath, a resident of Detroit. Before October 2019, she did not have a reliable internet connection. Now, a futuristic-looking teepee sits beside her house.“People pass by and they’re like, what’s that? It’s good to see something different,” she explained.The solar internet teepee was installed by the Equitable Internet Initiative and it’s partner organizations.“We pay for it,” Heath explained. “It's a nominal fee, you can afford it.”It serves nearby neighbors as well. “Around 50 or more,” Heath said. “Kids over there come over here and sit down and do their homework.”Whether it’s too expensive or just not available, the Equitable Internet Initiative, or EII, has been working on filling the gaps in internet access for years.“We prioritize homes that have no access to the internet at all, homes that have a low quality connection,” said Janice Gates, the Director of the Equitable Internet Initiative. “When the pandemic first happened and there was no access to the internet, all of the school children, their access to online learning didn't exist.”The EII is a partnership with three community organizations in Detroit, and the Detroit Community Technology Project.“We believe communication is a fundamental human right,” said Katie Hearn, the Director of the Detroit Community Technology Project. They all work together to get Detroit online. They’ve been doing so for years, all with funding from foundations and individuals.“It's been an issue, a known issue for a long time, whether you're looking at the schools or at access to gainful employment,” Hearn said. ”The COVID pandemic has shown a really bright light back on the digital divide.”While more players have come in to address the problem recently, including several fundraising efforts, EII continues doing its work in Detroit’s most under-served neighborhoods.“The digital divide is much more than a technology issue, it's much more than a policy issue, it really is people at the core,” Hearn explained.“I think there's a lot more work to do,” Castaneda-Lopez said. “In a way it's pushing us to be more creative about how we address this problem.” 3598

A woman in Pennsylvania cannot keep a winning lottery ticket worth more than million, a judge ruled, because of how she acquired the ticket.The case came down to how the Acme store, where Beverlie Seltzer works just outside of Philadelphia, handles lottery tickets that are printed by mistake on the automated terminal put in place by the state’s Lottery Commission.The judge noted the protocol is that the store must pay the commission for each mistake ticket, but the store can keep any winnings from those tickets.In the trial court’s summary says Seltzer began scanning the mistake tickets during her shift, shortly after the Match 6 drawing. She typically would discard losing tickets and leave winning tickets for the office coordinator to process.“As she scanned through them, she discovered that one of the mistake tickets was a winning ticket, in the amount of ,150,000.00. At this point, after learning the ticket was a winner, [instead of leaving the ticket for the coordinator to process the next day,] [Ms.] Seltzer took .00 in cash out of her purse, rang up her own transaction, and put the .00 in the register in an attempt to purchase the ticket. She was still on the clock at the time,” the court summary reads.Seltzer then reportedly told coworkers and her supervisor she won the lottery, “though claiming that she could not remember the time when she purchased the ticket.”Acme supervisors learned what happened after reviewing security tapes. When she was confronted, Seltzer denied it and contacted the lottery to claim the reward. Acme filed suit to determine the owner of the ticket.“When Ms. Seltzer in this instance deviated from the Acme procedures that she usually followed, she acted surreptitiously and was not forthcoming about the circumstances of the purchase,” the judge wrote. “Even viewing the evidence in the light most favorable to Ms. Seltzer, no reasonable fact-finder could conclude that Ms. Seltzer acted with the good faith belief that she was permitted by law or by Acme’s policies to give Acme in exchange for ,150,000. "The Acme store will now be entitled to the .15 million winnings. 2156

Alexandra Canosa, an associate producer on the Netflix series "Marco Polo," has filed a lawsuit in Manhattan Supreme Court alleging Harvey Weinstein raped, physically assaulted and verbally abused her over the course of five years.Weinstein "constantly threatened" Canosa and "made it clear that if she did not succumb to his demands for sexual contact or if she exposed his unwanted conduct there would be retaliation, including humiliation, the loss of her job and loss of any ability to work in the entertainment business," court documents allege.The lawsuit claims the former film executive insisted on meeting with Canosa in "isolated environments" and demanded sex. "Marco Polo" was produced by the Weinstein Company and debuted in 2014.Weinstein attorney Phyllis Kupferstein issued the following comment Tuesday to CNN:"Ali Canosa was a friend who had worked for The Weinstein Company for 10 years, traveled the world for the company and held several influential roles; overseeing many projects throughout the years. From someone who has been thought of as a good friend, involved only in a consensual relationship, these claims are not only mystifying to Mr. Weinstein, but deeply upsetting, and they cannot be supported by the facts."CNN received two updates within an hour of the statement. The second had no mention of a "consensual relationship" between Weinstein and Canosa. The Weinstein team had "no additional comment" in regards to the changes in the statements.Canosa alleged in Monday's amended lawsuit that Weinstein sexually assaulted her multiple times between 2010 and 2015.Canosa says she was sexually assaulted in a New York hotel room, "sexually assaulted, verbally assaulted, bullied and intimidated multiple times" in Los Angeles, "sexually assaulted and raped" in Malaysia, and "physically assaulted and verbally abused" inside Weinstein's room in Budapest.In August 2017, Canosa alleges, Weinstein verbally threatened her "not to speak to anyone about his abuse."In addition to Weinstein, the lawsuit lists The Weinstein Company, LLC, The Weinstein Company Holdings, LLC, Robert Weinstein -- Harvey's brother and co-founder of The Weinstein Company -- and nine other individuals associated with the Weinstein brand as defendants.Defendants "knew or should have known" about Weinstein's conduct, and didn't correct it. Instead, they "facilitated, hid, and supported" him, the complaint outlines.The Weinstein Company, LLC, and The Weinstein Company Holdings, LLC, were aware of Weinstein's history of sexual misconduct and facilitated his conduct by arranging meetings in hotel rooms and paying off sexual misconduct claims without corrective actions, according to the court filing.The companies had notice of Weinstein's actions against Canosa and other women, but failed to investigate further or "take reasonable steps" to do anything about them, the lawsuit alleges.Individuals who complained to the companies' human resources department for similar situations to what Canosa alleges "were subject to retaliation by Harvey Weinstein as a result of their complaints," the lawsuit says, adding that the failure to investigate claims of misconduct shielded Weinstein from consequences and enabled him to continue victimizing employees.CNN has reached out to Robert Weinstein's representatives for comment."The members of the board, including myself, did not know the extent of my brother's actions," he told The Hollywood Reporter in October 2017.Netflix declined to comment on the lawsuit.  3534

  

A worldwide study of the coronavirus released in the journal Cell indicates that the dominant strand of COVID-19 is causing the virus to spread faster.But the study’s authors said that even though the coronavirus is able to spread faster, the virus is no more or less severe than earlier in the outbreak.The study’s authors indicate that the virus has mutated, and that the Spike protein amino acid D614G has become the virus’ dominant strand.“Our global tracking data show that the G614 variant in Spike has spread faster than D614. We interpret this to mean that the virus is likely to be more infectious,” study author Bette Korber of Los Alamos National Laboratory.The federal government’s leading infectious disease expert Dr. Anthony Fauci addressed concerns that the virus could be more contagious in an interview with The Journal of the American Medical Association on Thursday.“The data is showing there’s a single mutation that makes the virus be able to replicate better and maybe have high viral loads,” Dr. Fauci said. “We don’t have a connection to whether an individual does worse with this or not; it just seems that the virus replicates better and may be more transmissible.”Korbe explained in the study how the dominant strand of the virus differs from earlier variants.“In infected individuals G614 is associated with lower RTPCR cycle thresholds, suggestive of higher upper respiratory tract viral loads, although not with increased disease severity,” Korbe said. “These findings illuminate changes important for a mechanistic understanding of the virus, and support continuing surveillance of Spike mutations to aid in the development of immunological interventions.”To read the full study, click here. 1731

  

A school trip for the eighth grade Mentor, Ohio Public Schools students to Washington D.C. was set and ready to go. Students were excited, bags were packed, lots of money was paid. But on Tuesday — the day before the trip — Discovery Tours, the company contracted by the school district to handle the trip, canceled. What's 511 students multiplied by 5 each? That's 2,505 paid.Discovery Tours told Mentor Public Schools it had to cancel the trip because the company was unable to receive final confirmation for the hotel rooms. The school district said it contacted the hotel itself to get more information."We were told by hotel management that, under advice from the hotel's legal counsel, all they could disclose to us is: Discovery Tours was unable to meet the contractual obligations," Superintendent Bill Porter wrote in a letter to parents.However, the school district said Discovery Tours told them otherwise. But the superintendent said even if the district was able to secure the hotel rooms itself, it wouldn't feel comfortable entrusting the travel company with its students."I am sure you are feeling angry as you read this, as all of us have been since we received the news late this afternoon," Porter wrote. "We know this is an educational experience students look forward to for years prior to 8th grade that is being taken from them for no apparent reason."Porter said the middle school principals will bring all eighth graders together on Wednesday to discuss the situation, and school will be in session as usual.Mentor Public Schools said it is also working to address the financial implications of the cancellation. "Refunds for the trip are undoubtedly on everyone's minds and at this time, we do not have full explanations yet, but I can assure you, we will work diligently to secure restitution," the letter said.Lots of eighth graders are going to bed with sad faces Tuesday night. 1956
