Wilkie, a San Diego native who attended La Jolla Country Day School according to the Air Force Academy, is survived by his wife, parents, and sister.In a statement, Wilkie's family said he was a humble man with a huge smile:"Our son Travis was born ready. His intense personal drive to achieve fueled his incredible accomplishments in academics, athletics and most recently, as an Air Force Academy graduate only weeks away from getting his wings. He made everything look effortless yet he invested great effort in everything. He had a huge smile and a humble heart. He was a great brother and great son. And he was deeply in love with his new wife Peyton. We are immensely proud of Travis and will cherish him forever."RELATED: San Diego veteran receives Congressional Gold Medal for WWII serviceSimmons said the cause of the Thursday morning accident is under investigation by an Air Force safety board that functions similarly to the National Transportation Safety Board.Simmons said it typically takes 30-60 days to determine the cause of such accidents."We are a close family," Simmons, 71st Flying Training Wing commander, said. "And when tragedies like this occur, every member of the U.S. military, Vance, Enid, feels it." 1954

Facebook has removed a network of suspected Russian-linked accounts and pages involved in organizing political events in the United States. The network is the most extensive effort to interfere in American politics that Facebook has found and made public ahead of November's midterm elections.The move comes as part of Facebook's efforts to prevent a repeat of 2016, when accounts connected to a Kremlin-linked troll group posing as Americans ran rampant on its platform.In briefings on Capitol Hill, Facebook has told lawmakers that it suspects a Russian group is behind more than 30 pages advocating US political stances, according to a congressional source briefed on the matter. One page promoted a "No Unite the Right 2" march -- a counter demonstration to a planned "Unite the Right" event to coincide with the one-year anniversary of the march in Charlottesville in which a woman was killed. There was also an effort to amplify the "Abolish ICE" message pushed by liberals, the source said.Publicly, Facebook is saying it does not know for sure who was behind the network, but is saying it has "found evidence of some connections between these accounts" and accounts that had been run by Russian trolls in the run-up to the 2016 presidential election. The company also said it had reported the network to law enforcement and to Congress.Asked by CNN to respond to the reports, Russian Foreign Ministry spokesperson Maria Zakharova said, "I hope the materials will be officially presented to the Russian side."Facebook said the "Resisters" page, which organized the "No Unite the Right 2" event, recruited real activists who "unwittingly helped build interest in" the event" and posted information about transportation, materials, and locations so people could get to the protests."Facebook said it has contacted the real activists.Nathaniel Gleicher, head of cybersecurity policy at Facebook, said in a post that the company was still investigating where the pages were run from but that, "Some of the activity is consistent with what we saw from the IRA before and after the 2016 elections." (The IRA is the Internet Research Agency, a Kremlin-linked troll group that has been indicted by Special Counsel Robert Mueller's office on charges related to an alleged conspiracy to defraud the United States.)He cautioned, "But there are differences, too. For example, while IP addresses are easy to spoof, the IRA accounts we disabled last year sometimes used Russian IP addresses. We haven't seen those here.""It's clear that whoever set up these accounts went to much greater lengths to obscure their true identities than the Russian-based Internet Research Agency (IRA) has in the past. We believe this could be partly due to changes we've made over the last year to make this kind of abuse much harder. But security is not something that's ever done," the company said in a statement released Tuesday afternoon," Facebook said in a statement Tuesday.The removed pages had more than 290,000 followers, the company said. The most followed Facebook pages were "Aztlan Warriors," "Black Elevation," "Mindful Being," and "Resisters."The company said the pages ran 150 ads for a total of approximately ,000. The ads were paid for in US and Canadian dollars, the company added. In 2016, the Internet Research Agency had purchased ads targeting Americans using rubles.Next week's event was not the only event the pages created. The pages created about 30 events since May 2017 and "The largest had approximately 4,700 accounts interested in attending, and 1,400 users said that they would attend," Facebook said.Facebook has sought guidance from U.S. intelligence agencies in its attempt to prevent a repeat of 2016, when its platform was used to meddle in U.S. politics and society. 3793

Facebook has set up a "war room" at its California headquarters as part of its plans to avoid a repeat of the 2016 election, when misinformation was rampant on the platform.The room is designed to bring leaders from the company's policy, legal, and security teams together as political campaigning ramps up in the final weeks before November's midterm elections.The company has been under intense scrutiny from Congress, federal investigators, and the media, after it emerged that Russian government-linked operatives manipulated its platform to target Americans in 2016.The company says it has hired thousands of new moderators, invested in artificial intelligence, enlisted the help of former US intelligence officials, and brought in new rules for political advertising — all in an effort to tackle a misinformation crisis.Samidh Chakrabarti, Facebook's director of elections and head of civic engagement, told CNN that the war room was "really the culmination of two years of massive investments we've made both in people and technology to ensure that our platforms are safe and secure for elections. So it builds upon work that we've done to crack down on fake accounts, on combating the spread of fake news on our platforms." 1239

Experts warned that a drop in air pollution from COVID-19 lockdowns would eventually come back as cars returned to the roads and businesses opened up. A study looking at air quality during the pandemic finds while the visible smog may have lifted in some areas, the air pollutants never really went away."It has been assumed that fewer cars on the road might have led to a decline in the level of air pollution outdoors and, in turn, reduce the number of cases of ill health linked to this pollution. However, our study -- contrary to research from places such as Wuhan in China, and Milan -- found no evidence of fine particulate air pollution declining in Scotland because of lockdown,” stated Dr. Ruaraidh Dobson, who led the study at the University of Stirling.Dr. Dobson and his group looked at the amount of fine particulate air pollution (referred to as PM2.5) in the first month of lockdown restrictions in Scotland. There was a 65 percent reduction in the number of vehicles on the roads, however there was little change in the levels of particulates.Looking at particles in the air between mid-March and mi-April of this year, then comparing that data to the same time period over the last few years, the researchers found little change in the amount of air pollution. They did notice a drop in nitrogen dioxide in 2020 samples, a compound specifically linked to car emissions.The team suggests traffic is not a key contributor to outdoor air pollution, and people may possibly be at greater risk of air pollution in their own homes from smoking and cooking appliances in small, enclosed, and poorly ventilated homes.“This could increase adverse health effects overall and also health inequalities – lower income people are more likely to smoke and to smoke indoors, and are likely to have smaller homes leading to higher PM2.5 concentrations from individual sources, due to smaller room volumes,” the study notes.The researchers express concern that if the severity of COVID-19 is related to air pollution exposure and respiratory issues, increased exposure to all sources of air pollution could increase the risk of serious complications from the disease. 2175

ESCONDIDO, Calif (KGTV) - An albino red-tailed boa constrictor named "Lemony Snicket" is back home.A man wearing a hood and backpack returned the snake on May 16 to the EcoVivarium children's museum in Escondido.

Lemony will undergo a 30-day quarantine.RELATED: Snake named 'Lemony Snicket' missing after unfortunate events at Escondido museumThe boa disappeared after a series of — ahem, "unfortunate" — events during a tour at the children's museum. Lemony was taken out of its cage for guests, before being locked back up.During the tour, however, museum officials said a man in his 20s excused himself from the group never to return. Later in the day, they said the boa was missing.A security camera facing Lemony's enclosure was also inoperable. Earlier the same day, the camera broke. A security expert said it appeared the camera was knocked out by some type of electrical charge.The museum said it would not press any charges against the person they believe to have taken the snake. 1144
