一 | Facebook今天宣布，未来三年将投资3亿美元在全球地方新闻上。此前，Facebook因其在全球新闻业务中的角色受到批评。 A "super fog" in Louisiana has caused a multi-car pileup on Interstate 55 near New Orleans, Louisiana, after severely lowering visibility, according to police.The crash, involving dozens of cars, occurred on Monday morning due to heavy fog conditions, according to Louisiana State Police. A long stretch of Interstate 55, a 24-mile-long highway over Lake Pontchartrain near New Orleans, is expected to be closed "for the foreseeable future," police said.Interstate 10 and Interstate 310 were also closed as a result of the crash, police said. Louisiana Gov. John Bel Edwards confirmed the accident in a statement Monday that there were fatalities in the crash, but did not say how many people were killed or injured.For hours after the crash, emergency crews worked to clear debris from both northbound and southbound lanes, according to state police.The super fog was caused by smoke from marsh fires burning in the region combined with dense fog developing in the area early Monday morning bringing extremely low visibility. In some spots, visibility was near zero, creating dangerous driving conditions.Super fogs typically form when condensed water vapor mixes with the smoke and moisture released from damp organic material smoldering from a nearby fire, such as brush, leaves and trees, according to the National Weather Service. Visibility can be lowered to less than 10 feet as a result, according to the NWS.This has been occurring in the region over the past several mornings, with the location of the densest fog and most dangerous conditions varying day to day, forecasts show.Super fogs can be especially dangerous when they develop near and over highways. The localized nature of the weather phenomenon means that visibility conditions can worsen rapidly within a very short distance, which can lead to a hazardous combination of sudden low to near-zero visibility and vehicles traveling at a high speed on a highway.The very limited visibility then hinders a driver's ability to react to changing conditions on a roadway.The National Weather Service issued a dense fog advisory for much of southeastern Louisiana on Monday morning, including from Baton Rouge to New Orleans.Over the past several days, the National Weather Service has been warning of the threat of dense fog during the early mornings in the region that would be worsened in some areas by nearby marsh fires. State police advised drivers to use their low-beam headlights if they can't see at least 500 feet in front of them.The fog dissipated by mid Monday morning, and all fog alerts have since been canceled.While areas of smoke will continue to be possible in the area as various marsh fires continue to burn, fog is not forecast to be a major issue Monday night, as weather conditions will be less favorable for fog development.Morning fog is not uncommon this time of the year for the region, but more than 86% of the state is currently battling extreme drought conditions, which is elevating fire danger. This could mean more instances of super fog in the coming days and weeks as cooler temperatures settle in, but the drought and wildfire risk persist.In addition, devastating drought and wildfire conditions continue to impact Louisiana. More than 60% of the state is now categorized at exceptional drought, the highest category of concern, according to the U.S. Drought Monitor. Just three months ago, 0% of the state was listed under exceptional drought."The combination of wildfire smoke and dense fog is dangerous, and I want to encourage all Louisianans in affected areas to take extreme caution when traveling," Edwards said in a statement.State troopers are working to notify families and investigate the exact cause of the crash, according to state police.It is unclear how many fatalities and injuries occurred as a result of the crash. The St. John the Baptist Parish Sheriff's Office directed media requests to Louisiana State Police.Additional information was not immediately available. Louisiana State Police did not immediately reply to ABC News' request for comment.。

二 | Facebook周二表示，对时间和金钱的投资是其先前帮助美国和世界其他地区新闻编辑创建和维护可行商业模式以确保其生存的计划的一个重大扩展。据即将接受投资的公司称，与以往对新闻业务的投资不同，Facebook最新一轮投资的特点是缺乏与Facebook产品的链接。据报道，Facebook此前几轮对新闻业务的投资旨在鼓励出版商依靠Facebook交付产品。在这种模式下，当Facebook的战略发生变化时，许多新闻机构的利益将受到影响。Facebook负责全球新闻合作的副总裁坎贝尔·布朗在一份声明中说：“我们将继续打击Facebook上的虚假新闻、虚假信息和低质量新闻。

三 | 同时，我们有机会和责任帮助当地新闻机构发展壮大。先前的批评者指出，Facebook为仇恨言论、错误信息和政治干预提供了平台。根据Facebook的计划，美国的第一轮投资将有助于增加当地报道的资源，帮助研究如何利用技术改进新闻收集和创造新产品，招募“受训社区记者”，并将他们安置在当地的新闻室。
