US-Russian crew returns from space station: NASA TV

WASHINGTON: A capsule carrying two US astronauts and a Russian cosmonaut from the International Space Station landed in snowy Kazakhstan on Wednesday after a five-and-a-half month mission, a NASA TV live broadcast showed.
The Soyuz spacecraft brought back Joe Acaba and Mark Vande Hei, from the US National Aeronautics and Space Administration, and Alexander Misurkin, from Russian space agency Roscosmos.
The capsule landed in the snow covered steppe some 90 miles southeast of the central city of Zhezkazgan at 8.31 a.m. (0231 GMT).
Misurkin was the first to emerge from the spacecraft, assisted by members of the Russian search and recovery team, and he was followed by Acaba who smiled and made a thumbs-up gesture.
The trio had spent five-and-a-half months at the ISS, a $100 billion lab that flies about 250 miles (400 km) above Earth.
The are due to be replaced by NASA’s Andrew Feustel and Richard Arnold, and Oleg Artemyev of Roscosmos, whose spacecraft will blast off from the Baikonur cosmodrome, also in Kazakhstan, on March 21.

YouTube, under pressure for problem content, takes down 58 mln videos in quarter

  • Google added thousands of moderators this year, expanding to more than 10,000, in hopes of reviewing user reports faster

WASHINGTON: YouTube took down more than 58 million videos and 224 million comments during the third quarter based on violations of its policies, the unit of Alphabet Inc’s Google said on Thursday in an effort to demonstrate progress in suppressing problem content.
Government officials and interest groups in the United States, Europe and Asia have been pressuring YouTube, Facebook Inc. and other social media services to quickly identify and remove extremist and hateful content that critics have said incite violence.
The European Union has proposed online services should face steep fines unless they remove extremist material within one hour of a government order to do so.
An official at India’s Ministry of Home Affairs speaking on the condition of anonymity on Thursday said social media firms had agreed to tackle authorities’ requests to remove objectionable content within 36 hours.
This year, YouTube began issuing quarterly reports about its enforcement efforts.
As with past quarters, most of the removed content was spam, YouTube said.
Automated detection tools help YouTube quickly identify spam, extremist content and nudity. During September, 90 percent of the nearly 10,400 videos removed for violent extremism or 279,600 videos removed for child safety issues received fewer than 10 views, according to YouTube.
But YouTube faces a bigger challenge with material promoting hateful rhetoric and dangerous behavior.
Automated detection technologies for those policies are relatively new and less efficient, so YouTube relies on users to report potentially problematic videos or comments. This means that the content may be viewed widely before being removed.
Google added thousands of moderators this year, expanding to more than 10,000, in hopes of reviewing user reports faster. YouTube declined to comment on growth plans for 2019.
It has described pre-screening every video as unfeasible.
The third-quarter removal data for the first time revealed the number of YouTube accounts Google disabled for either having three policy violations in 90 days or committing what the company found to be an egregious violation, such as uploading child pornography.
YouTube removed about 1.67 million channels and all of the 50.2 million videos that were available from them.
Nearly 80 percent of the channel takedowns related to spam uploads, YouTube said. About 13 percent concerned nudity, and 4.5 percent child safety.
YouTube said users post billions of comments each quarter. It declined to disclose the overall number of accounts that have uploaded videos, but said removals were also a small fraction.
In addition, about 7.8 million videos were removed individually for policy violations, in line with the previous quarter.
