By her second day on the job, Sarah Katz knew how jarring it can be to work as a content moderator for Facebook Inc. FB 0.69% She says she saw anti-Semitic speech, bestiality photos and video of what seemed to be a girl and boy told by an adult off-screen to have sexual contact with each other.
Ms. Katz, 27 years old, says she reviewed as many as 8,000 posts a day, with little training on how to handle the distress, though she had to sign a waiver warning her about what she would encounter. Coping mechanisms among content moderators included a dark sense of humor and swiveling around in their chairs to commiserate after a particularly disturbing post.
She worked at Facebook’s headquarters campus in Menlo Park, Calif., and ate for free in company cafeterias. But she wasn’t a Facebook employee. Ms. Katz was hired by a staffing company that works for another company that in turn provides thousands of outside workers to the social network.

Los Glaciares National Park is in the Austral Andes of southwest Argentina, near the Chilean border.Its many glaciers include Perito Moreno, best known for the dramatic icefalls from its front wall, into Lake Argentino. In the north, Mount Fitz Roy’s jagged peak rises above the mountain town of El Chaltén and Lake Viedma. The park is home to many birds, such as condors and black-chested buzzard eagles.
A new printing technique designed at Harvard University’s engineering school uses sound waves to control and fire droplets from a nozzle with incredible force, allowing researchers to print with liquids thicker and more viscous than ever before.
Honey, stem-cell-based inks and liquid metals all printed fluidly using these vibrations, which come from acoustic techniques that researchers had previously used to levitate liquids, not print with them.
The new technique was described in a paper published Aug. 31 in the journal Science Advances.

It has been a year since China jammed the works of recycling programs around the world by essentially shutting down what had been the industry’s biggest market. China’s National Sword policy, enacted in January 2018, banned the import of most plastics and other materials headed for that nation’s recycling processors, which had handled nearly half of the world’s recyclable waste for the past quarter century. The move was an effort to halt a deluge of soiled and contaminated materials that was overwhelming Chinese processing facilities and leaving the country with yet another environmental problem—and this one not of its own making.
In the year since, China’s plastic imports have plummeted by 99 percent, leading to a major global shift in where and how materials tossed in the recycling bin are being processed. While the glut of plastics is the main concern, China’s imports of mixed paper have also dropped by a third. Recycled aluminum and glass are less affected by the ban.

As President Trump delivered his inaugural address in 2017, a slight woman with feathered gray hair sat listening, bundled in a hooded white parka in a fenced-off V.I.P. section. Her name was Rosemary T. Vrablic. She was a managing director at Deutsche Bank and one of the reasons Mr. Trump had just taken the oath of office.
It was a moment of celebration — and a moment of worry for Ms. Vrablic’s employer.
Mr. Trump and Deutsche Bank were deeply entwined, their symbiotic bond born of necessity and ambition on both sides: a real estate mogul made toxic by polarizing rhetoric and a pattern of defaults, and a bank with intractable financial problems and a history of misconduct.

The climax of an offseason spent contemplating and debating the value of some of baseball’s biggest stars, as it turns out, was not the record-setting free agent contracts agreed to last month by Manny Machado and Bryce Harper but what came Tuesday: a massive extension in its final stages for Los Angeles Angels center fielder Mike Trout that zoomed past those other deals like a 600-foot home run.
Trout’s extension is worth “roughly” $430 million over 12 years, according to two people familiar with the negotiation — $100 million more than the 13-year, $330 million deal Harper signed weeks ago with the Philadelphia Phillies, which previously stood as the largest in North American team sports history. The new deal effectively adds 10 years and roughly $360 million to the $66.5 million Trout was already owed for 2019 and 2020 from the extension he signed in 2014, according to an industry source, but for luxury tax purposes it will be considered a 12-year contract.

The Okavango Delta is a vast inland river delta in northern Botswana.It’s known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. The Moremi Game Reserve occupies the east and central areas of the region. Here, dugout canoes are used to navigate past hippos, elephants and crocodiles. On dry land, wildlife includes lions, leopards, giraffes and rhinos.
A gigantic solar storm hit Earth about 2,600 years ago, one about 10 times stronger than any solar storm recorded in the modern day, a new study finds.
These findings suggest that such explosions recur regularly in Earth’s history, and could wreak havoc if they were to hit now, given how dependent the world has become on electricity.
The sun can bombard Earth with explosions of highly energetic particles known as solar proton events. These “proton storms” can endanger people and electronics both in space and in the air.
