A pair of durable boots is a must-have in anyone's winter wardrobe -- and a team of archaeologists has found a timeless pair in a very unlikely place.The skeleton of a man, dating back around 500 years, has been discovered face down in the mud under London's River Thames, with his thigh-high leather footwear remaining virtually intact.The find was made in Bermondsey, south London, by archaeologist working on London's new "super sewer," a ￡4.2 billion (.4 billion) tunnel that will capture, store and transfer raw sewage and rainwater that currently overflows into the river. The mystery of the man's sturdy (and sought after) footwear has prompted the team to investigate further.Leather was an expensive commodity in Tudor times, and it is unlikely someone would be buried wearing such a highly prized item, according to MOLA Headland, the firm leading the project -- meaning the man's demise was likely premature.But the company notes that the banks of the Thames were a hazardous place in the late 15th and early 16th century, to which the skeleton has been dated.He may have been "a fisherman, a mudlark or perhaps a sailor," the archaeologists speculated."By studying the boots we've been able to gain a fascinating glimpse into the daily life of a man who lived as many as 500 years ago," said Beth Richardson, Finds Specialist at MOLA Headland."They have helped us to better understand how he may have made his living in hazardous and difficult conditions, but also how he may have died. It has been a privilege to be able to study something so rare and so personal," Richardson added.The boots were built with extra soles and stuffed with moss or a similar material to help them last in tough terrain, according to the firm's conservation experts.Investigation of the man's bones has also provided further clues to the mystery.He was likely to have died under the age of 35 and had deep groves in his teeth most likely caused "by a repetitive action, like passing rope between his teeth as a fisherman might," according to the company. 2057

A two-year audit of Facebook's civil rights record found "serious setbacks" that have marred the social network's progress on matters such as hate speech, misinformation, and bias. The audit's leader, former American Civil Liberties Union executive Laura Murphy, was hired by Facebook in May 2018 to assess its performance on vital social issues. The final, 100-page report released Wednesday outlines a "seesaw of progress and setbacks" on everything from bias in Facebook's algorithms to content moderation, advertising practices, and voter suppression."The purpose of this Audit has always been to ensure that Facebook makes real and lasting progress on civil rights, and we do believe what’s listed below illustrates progress," Murphy said in the audit. "Facebook is in a different place than it was two years ago — some teams of employees are asking questions about civil rights issues and implications before launching policies and products. But as I’ve said throughout this process, this progress represents a start, not a destination. While the audit process has been meaningful and has led to some significant improvements in the platform, we have also watched the company make painful decisions over the last nine months with real-world consequences that are serious setbacks for civil rights."In a news release, Chief Operating Officer Sheryl Sandberg said that the release of the audit couldn't have come at a more important time. "Facebook stands firmly against hate," Sandberg said in the release. "Being a platform where everyone can make their voice heard is core to our mission, but that doesn’t mean it’s acceptable for people to spread hate. It’s not. We have clear policies against hate — and we strive constantly to get better and faster at enforcing them. We have made real progress over the years, but this work is never finished and we know what a big responsibility Facebook has to get better at finding and removing hateful content."The audit's recommendations are not binding. 2011

A report prepared for the Senate Intelligence Committee said Russian social media efforts to meddle in the 2016 presidential election included messaging in support of the Green Party 2016 presidential nominee Jill Stein.CNN obtained the report, prepared by New Knowledge, which said the Russian government-linked Internet Research Agency -- a well-known troll farm -- utilized all major social media platforms, and its efforts online included messaging in support of Stein's third party presidential effort.CNN has reached out to Stein for comment on the report.The mentions of Stein online came alongside related and disparate messages noted throughout the report, which said the Internet Research Agency's themes ranged from support for Vermont independent Sen. Bernie Sanders and the Black Lives Matter movement to the Tea Party and gun rights.A summation of the report's findings on "comprehensive anti-Hillary Clinton operations" said while the group's assumed Twitter personas had some pro-Clinton content, "the developed Left-wing Twitter personas were still largely anti-Clinton and expressed pro-Bernie Sanders and pro-Jill Stein sentiments."Likewise, the report said "pro-Bernie Sanders and Jill Stein content" were among the group's go-to themes across other platforms.The report's assertion about support for Stein echoed similar accounts in the past about Russian influence online. An indictment of Russian nationals earlier this year from special counsel Robert Mueller said the online effort included encouraging "minority groups not to vote in the 2016 US presidential election or to vote for a third-party US presidential candidate."Throughout her presidential bid, Stein called for a conciliatory approach with Russia, and she has compared Russian interference in the 2016 election with US efforts around the globe.Earlier this year, Stein told CNN she objected to turning over some documents to the Senate Intelligence Committee. She said at the time the requests were overly broad and unjustified."Legitimate concerns about interference in our election should not be twisted into a campaign of censorship, war-mongering and political intimidation against opposition to the bipartisan establishment," Stein said.CNN previously identified at least one occasion when the Russian group targeted Green Party activists.In the days after the shooting of Philando Castile in July 2016, the Russian group used a fake Black Lives Matter page called "Don't Shoot Us" in an attempt to organize a protest against the police.Brandon Long, the state party chairman of the Green Party of Minnesota, remembers hearing about the planned "Don't Shoot Us 'event. He told CNN, "We frequently support Black Lives Matter protests and demonstrations and we know pretty much all the organizers in town and that page wasn't recognized by anyone." CNN later reported "Don't Shoot Us" was run from Russia. 2905

A prank gone wrong landed two men in jail and has potentially scarred a little girl for life.At about 10 p.m. local time on Saturday, 25-year-old Vernon Barrett was wearing a clown mask and chasing his 6-year-old daughter outside their apartment in Boardman, Ohio, according to Youngstown's WKBN-TV.According to witnesses, the girl, obviously terrified, was screaming and ran into the unlocked apartment of neighbor Dion Santiago, 48.According to WFMJ-TV, Santiago told police that when the girl ran in to his apartment, he looked out the window and saw a man in a clown mask on the lawn. Santiago then grabbed his gun and fired a warning shot out the window.When police arrived at the scene, Barrett told them he was "playing a prank" on his daughter, according to WFMJ.WKBN reported that Barrett told officers he was trying to scare the girl because she'd been having behavioral issues at school and he thought this would straighten her out.Barrett was arrested for child endangering and inducing panic. Santiago, who admitted to police that he'd had a few beers, was arrested for using a gun while intoxicated.Clint Davis is a reporter for the Scripps National Desk.

A plan to raise San Diego's hotel tax to expand the convention center appears to be headed to the March 2020 ballot. The City Council voted 5-4 Monday to formalize its intention to place the tourist tax hike on next year's primary election. The measure, called "Yes! For a better San Diego," would raise the transient occupancy tax by as much as 3.25 percent per night, depending on location. Hotels closest to the heart of the city would see the tax rate increase the most. The revenue would fund a convention center expansion, homeless services and road repair. The council was split on its decision because voters passed Measure L in 2016. Measure L called for citizens initiatives to be placed on November general elections, when turnout is highest. However, the measure gave the City Council the option to move votes to different elections if it sees fit. It is still unclear whether the measure needs a simple majority or two-thirds support. The City Council is expected to formally place the tourist tax increase on the March ballot when it calls for the election in the fall. 1092
