 The scooter-sharing startup Lime continues to clash with its suppliers amid questions about the safety of its scooters.Chinese company Okai is pushing back on claims that it's the source of flawed Lime scooters.Earlier this month, Lime said it removed all of its scooters manufactured by Okai following reports that the baseboard where users stand can snap in half and endanger riders. Some riders have suffered injuries, and an Okai scooter may have contributed to a fatality. Lime uses scooters from multiple manufacturers, but doesn't reveal exactly how many.In late October, Lime stated the baseboard on its Okai models could break if ridden off a curb at high speeds.Okai said Friday Lime's claims are "groundless" and the faulty scooters come from another supplier."We feel it necessary to make cautions to the public on the credibility of such statements made by Lime," Okai said in a statement sent to CNN Business on Friday. "Obviously, Lime has other suppliers whose scooters broke."Lime declined to comment on whether it has recalled scooters from other manufacturers.Photos on social media and in news reports revealed Lime scooters with broken floorboards -- some of which match images of the scooter model Okai says it provided to Lime. But not all looked the same. The Okai model has a distinct set of lights and screws, the manufacturer said in its statement.Okai said it sold 32,000 scooters to Lime, but the company has not revealed how many scooters it has removed from streets. When it recalled some scooters over battery concerns earlier this year, the issue impacted less than 0.01% of its fleet, Lime said.The company said it is working with the US Consumer Product Safety Commission to investigate its Okai scooters.In 2017, Lime launched as LimeBike, a dockless bikesharing startup. But this year it shifted its focus to scooters after Bird, a Santa Monica startup, pioneered a popular scooter-sharing service. Lime has since raised hundreds of millions of dollars, including from Uber. Lime operates in 10 countries and more than 85 US cities.Scooters have been shown to reduce car trips, earning praise from environmentalists and city experts. But safety questions have followed the company's rapid expansion. In September, a Dallas man died shortly after a crash while riding a Lime scooter. Police discovered the scooter was broken in half, but the company hasn't said if the man was riding an Okai scooter.Along with fellow Lime supplier Ninebot, Okai is calling on scooter companies to do more to protect scooters from the wear-and-tear of daily use."It is the operator's responsibility to ensure proper and prompt management and maintenance of the scooters it puts into the co-sharing market," Okai said.Lime has already taken some steps to tackle safety concerns. It announced a million program to distribute 250,000 helmets and educate riders on safety practices. Lime recently unveiled a new scooter with safety improvements, such as larger wheels, intended to better handle potholes and uneven roads.Companies are racing to meet demand and expand to new cities.But the Silicon Valley-backed companies have grown at a?breakneck pace, which has drawn criticism for introducing problems at a scale that wouldn't occur with steadier growth. Some view scooters as clutter because they're sometimes parked incorrectly, such as blocking sidewalks.According to Tony Ho, vice president of business development at the Chinese company Ninebot, which makes a majority of the shared scooters in use worldwide, the scooter-sharing industry is so new that issues continue to pop up.He said Ninebot plans to release a new model later this year that's better designed for harsh conditions. Shared scooters are typically ridden a half-dozen times a day on roads of varying quality, and in inclement weather. Scooters are often thrown to the ground, or tossed in the back of trucks to be charged. And minor cracks can expose components, leading to malfunctions."There's room to improve in how to operate, and how to train chargers," Ho said of the scooter-sharing startups. "This is almost like a new test for us. The product needs to sustain a real industrial type of environment."Segway is also shifting the battery in its scooters to the baseboard. This will lower the center of gravity, making them less likely to tip over and expose riders to head injuries."It's gonna be a beast," Ho said of the new scooter. 4558

(CNN) -- Boxer Patrick Day died Wednesday, four days after he was knocked out during his bout with Charles Conwell on Saturday night in Chicago.Day, 27, succumbed to a traumatic brain injury he suffered that night, according to a statement from his promoter, Lou DiBella of DiBella Entertainment."He was surrounded by his family, close friends and members of his boxing team, including his mentor, friend and trainer Joe Higgins," DiBella said in a statement. "On behalf of Patrick's family, team, and those closest to him, we are grateful for the prayers, expressions of support and outpouring of love for Pat that have been so obvious since his injury."In a Twitter post addressed to Day on Tuesday, Conwell wrote he "never meant this to happen to you.""All I wanted to do was win. If I could take it all back, I would," Conwell wrote. "No one deserves this to happen to them. I replay the fight over and over in my head thinking what if this never happened and why did it happen to you."After Conwell, a 2016 Olympic boxer, knocked Day out in the 10th round, Day appeared to be down for several minutes as a medical team rushed in to assess his injuries. Eventually he was taken out of the ring on a stretcher, and transported to Northwestern Memorial Hospital.DiBella said that Day didn't need to box as he came from a good family, was educated and could have made a living in some other way."He chose to box, knowing the inherent risks that every fighter faces when he or she walks into a boxing ring," DiBella said. "Boxing is what Pat loved to do. It's how he inspired people and it was something that made him feel alive."Conwell was in control of the fight in Wintrust Arena from the beginning, according to ESPN.Before he became a professional fighter, Day was a highly decorated amateur. He won two Nationals titles, the New York Golden Gloves tournament and was an Olympic Team alternate, all in 2012.He turned pro in 2013 and captured the WBC Continental Americas championship in 2017 and the IBF Intercontinental championship in 2019. In June 2019, he was rated in the top 10 by both the WBC and IBF. As of Saturday, Day's record stood at 17-4-1, with six knockouts.Dibella said it is "very difficult to explain away or justify the dangers of boxing at a time like this.""While we don't have the answers, we certainly know many of the questions, have the means to answer them, and have the opportunity to respond responsibly and accordingly and make boxing safer for all who participate," DiBella Entertainment said."This is a way we can honor the legacy of Pat Day."CORRECTION: A previous version of this story misidentified Patrick Day's promoter. His name is Lou DiBella. 2696

 Conservative rhetoric about migrants -- like the group making their way through Mexico, the one President Donald Trump called an "invasion" -- might lead some to believe that migrants are a threat to American health, a strain on the health care system and damaging to the economy. But a new series of papers presented at a UN Intergovernmental Conference this week and published Wednesday in the journal Lancet says that, based on evidence, that's not true.Most migrants have a mortality advantage, or greater life expectancy, than people in their host countries, according to the new research. This was true for the majority of diseases.However, separating migrants from their families can be bad for children's health, as can keeping them in detention or continuously threatening them with deportation, the research showed.More than 1 billion people were "on the move" around the world this year, and a quarter of them were crossing international borders, according to researchers who worked on the report.With so many people on the move or having moved in 2018, the authors argue that "migration is the defining issue of our time," particularly as nationalist and anti-immigrant sentiment grows. 1267

 People around the U.S. experienced some internet downtime on Monday. The outage was brief and service has been restored.The culprit was a configuration issue from Level 3, a telecommunications and internet service provider owned by CenturyLink. In a statement to CNN Tech, CenturyLink said a "configuration error" disrupted service and technicians restored service in 90 minutes.CenturyLink declined to provide further details.Though Level 3 was responsible for the issue, it affected other internet providers like Comcast. That's because Level 3's infrastructure delivers content for other internet services.Comcast said the service disruption to its Xfinity internet service has been resolved.According to reports from Down Detector, a website that monitors internet outages, Comcast and Level 3 connectivity was impacted nationwide beginning around 10 a.m. Pacific.Other internet service providers including Spectrum, Verizon, and AT&T showed a spike in connectivity issues, too, though they were not as widespread. (AT&T has agreed to acquire CNN's parent company Time Warner, and the deal is pending regulatory approval.) It's unclear if the spikes were related to the Level 3 outage.The website does not provide numbers of people affected.Following public complaints of widespread outages, rumors temporarily circulated online that the outage was a coordinated hack of some sort. But, as CenturyLink confirmed, it was a misconfiguration.CenturyLink completed its acquisition of Level 3 earlier this month. 1548
