Facebook took a hard look in the mirror with a post Monday questioning the impact of social media on democracies worldwide and saying it has a “moral duty” to understand how it is being used.

Over the past 18 months, the company has faced growing criticism for its limited understanding of how misinformation campaigns and governments are using its service to suppress democracy and make people afraid to speak out.

“I wish I could guarantee that the positives are destined to outweigh the negatives, but I can’t,” wrote Samidh Chakrabarti, Facebook’s product manager of civic engagement.

Since the 2016 U.S. presidential election, Facebook has been looking more critically at how it is being used. Some of what it found raises questions about company’s long-standing position that social media is a force for good in people’s lives.

In December, in a post titled “Is Spending Time on Social Media Bad for Us?” the company wrote about its potential negative effects on people.

The self-criticism campaign extended to Facebook CEO Mark Zuckerberg’s personal goals. Each year he publicly resolves to reach one personal goal, which in the past included learning Mandarin, reading more books and running a mile every day.

This year, Zuckerberg said his goal is to fix some of the tough issues facing Facebook, including “defending against interference by nation states.”

Foreign Interference

During the 2016 U.S. election, Russian-based organizations were able to reach 126 million people in the U.S. with 80,000 posts, essentially using social media as “an information weapon,” wrote Chakrabarti. The company made a series of changes to make politics on its site more transparent, he wrote.

False News

Facebook is trying to combat misinformation campaigns by making it easier to report fake news and to provide more context to the news sources people see on Facebook.

“Even with these countermeasures, the battle will never end,” Chakrabarti wrote.

One of the harder problems to tackle, he said, are so-called “filter bubbles,” people only seeing news and opinion pieces from one point of view. Critics say some social media sites show people only stories they are likely to agree with, which polarizes public opinion.

One obvious solution – showing people the opposite point of view – doesn’t necessarily work, he wrote. Seeing contrarian articles makes people dig in even more to their point of view and create more polarizations, according to many social scientists, Chakrabarti said.

A different approach is showing people additional articles related to the one they are reading.

Reaction to Facebook’s introspection was mixed with some praising the company for looking at its blind spots. But not everyone applauded.

“Facebook is seriously asking this question years too late,” tweeted Jillian York, director for international freedom of expression for the Electronic Frontier Foundation.

No cashiers, no lines, no registers — this is how Amazon sees the future of in-store shopping.

The online retailer opened its Amazon Go concept store to the public Monday, selling milk, potato chips and other items typically found at a convenience shop. Amazon employees have been testing the store, which is at the bottom floor of the company’s Seattle headquarters, for about a year.

The public opening is another sign that Amazon is serious about expanding its physical presence. It has opened more than a dozen bookstores, taken over space in some Kohl’s department stores and bought Whole Foods last year, giving it 470 grocery stores.

But Amazon Go is unlike its other stores. Shoppers enter by scanning the Amazon Go smartphone app at a turnstile. When they pull an item of the shelf, it’s added to their virtual cart. If the item is placed back on the shelf, it is removed from the virtual cart. Shoppers are charged when they leave the store.

The company says it uses computer vision, machine learning algorithms and sensors to figure out what people are grabbing off its store shelves.

Amazon says families can shop together with just one phone scanning everyone in. Anything they grab from the shelf will also be added to the tab of the person who signed them in. But don’t help out strangers: Amazon warns that grabbing an item from the shelf for someone else means you’ll be charged for it.

At about 1,800 square feet, the store will also sell ready-to-eat breakfasts, lunches and dinners. Items from the Whole Foods 365 brand are also stocked, such as cookies, popcorn and dried fruit.

The company had announced the Amazon Go store in December 2016 and said it would open by early 2017, but it delayed the debut while it worked on the technology and company employees tested it out.

Media mogul Rupert Murdoch on Monday called on Facebook to pay “trusted” news publishers a carriage fee, similar to the model used by cable companies, amid efforts by the social media company to fight misinformation on its platform.

“Facebook and Google have popularized scurrilous news sources through algorithms that are profitable for these platforms but inherently unreliable,” Murdoch, who controls the Wall Street Journal as executive chairman of News Corp., said in a statement.

Facebook Chief Executive Mark Zuckerberg said on Friday his company would fight misinformation and sensationalism on its platform by using member surveys to identify “trustworthy” outlets.

“There has been much discussion about subscription models but I have yet to see a proposal that truly recognizes the investment in and the social value of professional journalism,” Murdoch said.

The quality of news on Facebook has been called into question after alleged Russian operatives and spammers spread false reports on the site, including during the 2016 U.S. election campaign.

Facebook and Google did not immediately respond to requests for comment.

Assessing someone’s medical status was easy on the TV series, Star Trek. Dr. McCoy just waved his tricorder over the patient, and any broken bones, concussions or internal bleeding were instantly revealed.

While in real life, ultrasounds and x-rays help physicians diagnose everything from breast cancer to kidney stones, those scans can not reveal what is inside the masses.  Having that immediate knowledge could help millions of patients avoid unneeded stress and surgery.  

Purdue University Biomedical Engineering professor Ji-Xin Cheng has devoted his life’s work to technology that will be able to provide that internal view. He and his team have developed several medical tools that help diagnose patients using sound and light. “Eventually we want to make a device like the tricorder in Star Trek,” he explains, “so our dream is to make a movie into a real practice.”

Label-free imaging

In conventional medicine, surgeons must either cut out suspect tissue for analysis, or risk exposing already very sick patients to fluorescent dyes and nanoparticles.  These “labels” light up lesions so doctors can study them.

Team member Jesse Vhang explains their technique – called “label-free imaging” – eliminates more invasive or toxic procedures by bouncing light off molecules in the tumor.

“We do not need a label,” he points out. “We can basically look at the vibrations of the molecules and these vibrations can generate signals in our microscope.”

Those vibrations serve as molecular fingerprints, unique to each type of molecule.  The patterns can be mapped to identify such things as lipids, proteins, and nucleic acids.  In essence, the devices give doctors the ability to look at a patient in three instead of two dimensions.

Vhang says, “For example we could use this to image biological samples from patients.  We can see if the patient has cancer, which usually accumulates a lot of lipids.” The label-free imaging devices have shown promise in identifying kidney, liver, and breast cancer.  

MarginPAT

One device, the MarginPAT, funded by the National Institute of Health, will also help breast cancer surgeons remove tumors more efficiently and accurately.  In the United States, about a quarter of all breast cancer patients must undergo a second surgery to remove missed malignant cells. The developers expect MarginPAT will dramatically reduce that number.

Cheng and his partner, Dr. Pu Wang, founded Vibronix to manufacture the device.  Wang says it could revolutionize medicine around the world.

“I think this will be good in mainland China where medical practice is not as good as the tier one hospitals in the big cities or aboard.  They will be able to use the setup to provide the same surgery as the big city doctors.”

If all goes as planned, the MarginPAT will be on the market within three years and several more of Cheng’s label-free imaging devices will not be far behind, making his dream of a real Star Trek tricorder one step closer to reality.

Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface of Mars have been successful and a full-power run is scheduled for March, officials said on Thursday.

National Aeronautics and Space Administration and U.S. Department of Energy officials, at a Las Vegas news conference, detailed the development of the nuclear fission system under NASA’s Kilopower project.

Months-long testing began in November at the energy department’s Nevada National Security Site, with an eye toward providing energy for future astronaut and robotic missions in space and on the surface of Mars, the moon or other solar system destinations.

A key hurdle for any long-term colony on the surface of a planet or moon, as opposed to NASA’s six short lunar surface visits from 1969 to 1972, is possessing a power source strong enough to sustain a base but small and light enough to allow for transport through space.

“Mars is a very difficult environment for power systems, with less sunlight than Earth or the moon, very cold nighttime temperatures, very interesting dust storms that can last weeks and months that engulf the entire planet,” said Steve Jurczyk, associate administrator of NASA’s Space Technology Mission Directorate.

“So Kilopower’s compact size and robustness allows us to deliver multiple units on a single lander to the surface that provides tens of kilowatts of power,” Jurczyk added.

Testing on components of the system, dubbed KRUSTY, has been “greatly successful — the models have predicted very well what has happened, and operations have gone smoothly,” said Dave Poston, chief reactor designer at the Los Alamos National Laboratory.

Officials said a full-power test will be conducted near the middle or end of March, a bit later than originally planned.

NASA’s prototype power system uses a uranium-235 reactor core roughly the size of a paper towel roll.

President Donald Trump in December signed a directive intended to pave the way for a return to the moon, with an eye toward an eventual Mars mission.

Lee Mason, NASA’s principal technologist for power and energy storage, said Mars has been the project’s main focus, noting that a human mission likely would require 40 to 50 kilowatts of power.

The technology could power habitats and life-support systems, enable astronauts to mine resources, recharge rovers and run processing equipment to transform resources such as ice on the planet into oxygen, water and fuel. It could also potentially augment electrically powered spacecraft propulsion systems on missions to the outer planets.

Move over traditional billboards. Three-dimensional, slightly hypnotic holograms may soon replace two-dimensional signs and ads. Several companies with this technology said 3D holograms will revolutionize the way businesses and brands talk to potential customers.

“It’s already replacing billboards, LED screens, LCD screens, because there hasn’t been any revolution in the display industry for decades,” said Art Stavenka, founder of Kino-mo, a company with offices in London and Belarus. 

The main hardware of the technology is a blade that emits a strip of light creating holograms of images and words. Multiple blades can be synchronized for larger holograms.

“As soon as this piece of hardware spins, you stop seeing hardware and you start seeing (a) hologram, and the piece of hardware spins fast enough so a human eye does not see any rotation, and it sees the amazing holographic image,” said Stavenka.

Another company developing this type of device is Hologruf, with a presence in both the U.S. and China. 

“In the not so distant future on every street corner, there will be these types of ad displays just like in a science fiction movie,” said Hologruf’s Quan Zhou. 

The applications for 3D holographic displays include shopping centers, train stations and restaurants. 

For franchises such as fast food restaurants that want these displays in more than one location, “they have the capability to manage multiple devices around the world from a central location,” said Hologruf’s co-founder, Ted Meng. 

The cost of a blade ranges anywhere from around $1,300 to just over $3,000, depending on the manufacturer. 

The competition has begun for this technology. Kino-mo has customers in 50 countries on almost every continent. It will be releasing an outdoor version sometime in 2018. Hologruf said it already has a product to replace outdoor billboards.

“We can make it to be water proof, wind proof and work under all kinds of extreme environmental conditions,” said Zhou.

So what would Tokyo or Times Square in New York look like in a few years? Stay tuned.

Social media giant Facebook said Friday that it would begin to prioritize “trustworthy” news outlets on its site in order to counteract “misinformation.”

The company said it would ask its more than 2 billion users to rank the news organizations they trusted in order to prioritize “high-quality news” over less trusted sources. It said the new ranking system would seek to separate news organizations trusted only by their own subscribers from ones that are broadly trusted across society.

Facebook Chief Executive Mark Zuckerberg wrote in a blog post that the company was not “comfortable” deciding which news sources are the most trustworthy in a “world with so much division.”

“There’s too much sensationalism, misinformation and polarization in the world today,” he wrote.

“Social media enables people to spread information faster than ever before, and if we don’t specifically tackle these problems, then we end up amplifying them,” Zuckerberg added.

​Outside experts rejected

He said Facebook considered asking outside experts to choose the most reputable news sources, but that doing so would most likely have led to an “objectivity problem.” He said the company decided to rely on member surveys as the most “objective” way to rank trust in news sources.

Zuckerberg said it’s important that Facebook’s News Feed “promotes high-quality news that helps build a sense of common ground.”

He also announced that Facebook would shrink the content on its News Feed from 5 percent to 4 percent. This means users will see fewer posts from news organizations while scrolling through their feeds in favor of more posts from friends.

Facebook has been struggling with how to handle its distribution of news in an era of fake news and claims of media bias.

The social media company has faced accusations that it helped spread misinformation as well as Russian-linked content meant to influence the 2016 U.S. elections.

Also last year, U.S. Republican lawmakers expressed concern that Facebook was suppressing stories from conservative news sources.

The Pew Research Center has found that more than two-thirds of Americans are getting at least some of their news from social media, making such outlets prime sources of information.

A former software engineer for IBM in China has been sentenced to five years in prison for stealing the source code for highly valuable software developed by the tech company, the U.S. Justice Department announced Friday.

Xu Jiaqiang, 31, was sentenced Thursday by a federal judge in White Plains, New York, months after he pleaded guilty to three counts of economic espionage and three counts of theft, possession and distribution of trade secrets.

Prosecutors said Xu stole the source code for computer performance-enhancing software while working for IBM from 2010 and 2014, with the intent to benefit China’s National Health and Family Planning Commission. 

Acting Assistant Attorney General Dana J. Boente of the Justice Department’s national security division said the agency “will not hesitate to pursue and prosecute those who steal from American businesses.”

Xu, a Chinese national, “is being held accountable for engaging in economic espionage against an American company,” Boente said in a statement.

U.S. Attorney Geoffrey S. Berman for the Southern District of New York said, “Xu’s prison sentence should be a red flag for anyone attempting to illegally peddle American expertise and intellectual property to foreign bidders.”

IBM was not identified in court documents. But a LinkedIn profile of Xu identifies him as a system developer for IBM in China from 2010 to 2014 with a master’s degree from the University of Delaware.

A Justice Department spokesman declined to say whether the company in question was IBM. IBM didn’t immediately respond to a request for comment.

Xu appeared on the FBI’s radar screen in 2014 after the bureau received a tip that Xu, who had by then left the company, claimed to have the source code to one of company’s most closely guarded software packages and was using it in “business ventures” unrelated to its clients.  

The software is described as a cluster file system sold to governments and large companies and used to enhance computer performance.

Undercover FBI agents posing as an investor and project manager for a large data storage company approached Xu, who tried to sell them the software and admitted that he’d built it with stolen source code, according to prosecutors.

IBM employees later confirmed to the FBI that the software had been built by someone with access to the company’s proprietary source code.

Xu was arrested in December 2015 after meeting with an undercover agent at a White Plains hotel.

Social media companies Facebook, Twitter and Google’s YouTube have greatly accelerated their removals of online hate speech, reviewing over two thirds of complaints within 24 hours, new EU figures show.

The European Union has piled pressure on social media firms to increase their efforts to fight the proliferation of extremist content and hate speech on their platforms, even threatening them with legislation.

Microsoft, Twitter, Facebook and YouTube signed a code of conduct with the EU in May 2016 to review most complaints within a 24-hour timeframe.

The companies managed to meet that target in 81 percent of cases, EU figures seen by Reuters show, compared with 51 percent in May 2017 when the European Commission last monitored their compliance with the code of conduct.

EU Justice Commissioner Vera Jourova has said previously she does not want to see a removal rate of 100 percent as that could impinge on free speech. She has also said she is not in favor of legislating as Germany has done.

 A law providing for hefty fines for social media companies if they do not remove hate speech quickly enough went into force in Germany this year.

“I do not hide that I am not in favor of hard regulation because the freedom of speech for me is almost absolute,” Jourova told reporters in December.

“In case of doubt it should remain online because freedom of expression is [in a] privileged position.”

Of the hate speech flagged to the companies, almost half of it was found on Facebook, the figures show, while 24 percent was on YouTube and 26 percent on Twitter.

The most common ground for hatred identified by the Commission was ethnic origins, followed by anti-Muslim hatred and xenophobia, including expressions of hatred against migrants and refugees.

Following pressure from several European governments, social media companies stepped up their efforts to tackle extremist content online, including through the use of artificial intelligence.

The Commission will likely issue a recommendation, a soft law instrument, on how companies should take down extremist content related to militant groups at the end of February, an official said, as it is less nuanced than hate speech and needs to be taken offline more quickly.

A major hacking operation tied to Lebanon’s main intelligence agency has been exposed after careless spies left hundreds of gigabytes of intercepted data exposed to the open internet, according to a report published Thursday.

Mobile security firm Lookout, Inc. and the Electronic Frontier Foundation, a digital rights group, said the haul, which includes nearly half a million intercepted text messages, had simply been left online by hackers linked to Lebanon’s General Directorate of General Security.

“It’s almost like thieves robbed the bank and forgot to lock the door where they stashed the money,” said Mike Murray, Lookout’s head of intelligence. Lookout security researcher Michael Flossman said the trove ran the gamut, from Syrian battlefield photos to private phone conversations, passwords and pictures of children’s birthday parties.

“It was everything. Literally everything,” Flossman said.

Discoveries of state-sponsored cyberespionage campaigns have become commonplace as countries in the Middle East and Asia scramble to match the digital prowess of the United States, China, Russia and other major powers. But Lookout and EFF’s report is unusual for the amount of data uncovered about the spying campaign’s victims and its operators.

Notably, their report drew on data generated by suspected test devices — a set of similarly configured phones that appear to have been used to try out the spy software — to potentially pinpoint the hackers’ exact address.

The report said the suspected test devices all seemed to have connected to a WiFi network active at the intersection of Beirut’s Pierre Gemayel and Damascus Streets, the location of the bulky, sandstone-colored high-rise that houses Lebanon’s General Directorate of General Security. The Associated Press was able to at least partially verify that finding, sending a reporter to the area around the heavily guarded, antennae-crowned building Wednesday to confirm that the same WiFi network was still broadcasting there. Other data also points to the spy agency: the report said the internet protocol addresses of the spyware’s control panels mapped to an area just south of the GDGS building.

Electronic Frontier Foundation Director of Cybersecurity Eva Galperin said the find was remarkable, explaining that she could think of only one other example where researchers were able to pin state-backed hackers to a specific building.

`We were able to take advantage of extraordinarily poor operational security,” she said.

The GDGS declined to comment ahead of the report’s publication.

The 49-page document lays out how spies used a network of bogus websites and malicious smartphone apps — such as WhatsApp, Telegram, Threema and Signal — to steal passwords or pry into communications, eavesdropping on conversations and capturing at least 486,000 text messages. Some victims were tricked into visiting the websites or downloading the rogue apps by booby trapped messages sent over WhatsApp, the report said. Others may have had malicious programs installed physically when they were away from their phones. Still more may have been lured into compromising their devices by a set of apparently fake Facebook profiles set up to look like attractive young Lebanese women.

EFF and Lookout said the spying stretched over 21 different countries, including the United States and several European nations, but they declined to identify any of the victims except in general terms, saying that there were thousands of them and that in many cases it wasn’t always obvious who they were.

Murray said relevant authorities had been notified of the spying but declined to go into further detail.

Lebanon has historically been a hub for espionage and Lebanese spies have a documented interest in surveillance software. In 2015, for example, the internet watchdog group Citizen Lab published evidence that GDGS had tapped FinFisher, a spyware merchant whose tools have been used to hack into the computers of several African and Middle Eastern dissidents.

The hacking campaign exposed Thursday by EFF and Lookout — which they dub “Dark Caracal” — was discovered in the wake of an entirely different cyberespionage campaign targeting Kazakh journalists and lawyers.

An EFF report on the Kazakh campaign published in 2016 caught the attention of researchers at Lookout, who swept through the company’s vast store of smartphone data to find a sample of the smartphone surveillance software mentioned in the write-up. It was while pulling on that string that investigators stumbled across the open server full of photos, conversations and intercepted text messages — as well as the link to Lebanon.

Galperin and Murray both said researchers were marshalling more evidence and that more revelations were coming.

“Stay tuned,” Murray said.

The Catholic church is going digital in Paris.

 

The city’s diocese will introduce a system allowing contactless card payments during Sunday’s mass at Saint Francois de Molitor, a church located in an upscale and conservative Paris neighborhood.

 

The diocese explained Thursday that five connected collection baskets with a traditional design will be handed out to mass attenders during the service. They will choose on a screen the amount they want to donate – from 2 to 10 euros ($2.4 to $12.2) – and their payment will be processed in “one second.”

 

The diocese insisted “this new gesture remains extremely close to the usual” one, yet parishioners will still be able to use cash for their donations.

 

According to the diocese, donations amount to 79 percent of its resources.

 

“Mass collection represents 14 percent of that contribution,” it said in a statement. “That’s about 98 euros on average, per year and per faithful.” It explained that the move is meant “to anticipate the gradual disappearance of cash money.”

 

This is not the French Catholic church’s first attempt to keep up with new technologies.

 

Since 2016, a smartphone app for making donations called “La Quete,” which translates as “The Collection,” has been introduced across 28 French dioceses and more than 2,000 parishes.

 

About 4,000 donations have been made over 14 months in the eight Paris parishes that have been testing the app, with the average amount spent coming in at 4.71 euros.

 

“The Church is committed to supporting everyone in the new ways of life and consumption,” the Paris diocese said. “The dematerialization of the means of payment is also part of the challenges the Church has to take up. Whether through a connected basket, with contactless payment, or through a smartphone app.”

 U.S. President Donald Trump said on Wednesday he would announce a decision soon on whether to slap tariffs on imported solar panels, and quipped that when countries dump subsidized panels in the United States, “Everybody goes out of business.”

The solar industry is anxiously awaiting the decision, which will have wide-reaching implications for the sector. Domestic panel producers opposed to cheap imports would benefit from a tariff. But installers that have relied on the lower-cost hardware for their recent breakneck growth would suffer.

In an interview with Reuters, Trump declined to say how he would land on the case — which was triggered last year by a domestic manufacturer’s trade grievance — but complained about the effect of imports on U.S. panel makers.

“You know, they dump ’em — government-subsidized, lots of things happening — they dump the panels, then everybody goes out of business,” he said.

Asked when the decision would be announced, he said: “Pretty soon. Honestly, pretty soon.”

According to a process governed by the International Trade Commission, Trump has until Jan. 26 to make his decision.

Bankrupt domestic panel producer Suniva triggered Trump’s consideration of tariffs last year when it filed a trade case arguing it could not compete with cheap imports. About 95 percent of the solar cells and panels sold in the United States are made abroad, with most coming from China, Malaysia and the Philippines, according to SPV Market Research.

Suniva was later joined in the case by the U.S. arm of German manufacturer SolarWorld AG.

In October, Trump received a range of options from members of the U.S. International Trade Commission to protect domestic producers, but he has broad leeway to come up with his own alternative or do nothing at all.

Suniva is seeking strong measures.

“A robust tariff will allow Suniva to restart its factories and rehire employees,” Suniva spokesman Mark Paustenbach said.

Jobs at stake

Only about 14 percent of the solar industry’s 260,000 jobs are in manufacturing. The trade case has fueled anxiety among installers that make up most of the rest of the industry and rely on low-priced imports.

The installation sector’s trade group, the Solar Energy Industries Association, has campaigned against tariffs, saying they would drive up the price of solar and cripple demand, eliminating tens of thousands of jobs and ultimately hurting the manufacturers that sought them in the first place.

“I’m staying optimistic that the business aspect of this will come through in the end,” said George Hershman, president of Swinerton Renewable Energy, a privately held firm that constructs large-scale solar projects.

Hershman said Swinerton employed 2,000 full-time employees and up to 8,000 temporary workers, but added several of its projects had been placed on hold pending Trump’s decision. 

“If you add 50 percent to the cost of the job, it may not be economic,” Hershman said.

Solaria Corp, a U.S. company that produces panels in both California and South Korea, also opposes tariffs, according to Chief Executive Suvi Sharma. The company said a recent $23million financing round took months longer than it should have partly because of investor jitters about the case.

“The best thing would be to have this whole thing go away,” Sharma said.

Facebook Inc said on Wednesday it would conduct a new, comprehensive search of its records for possible propaganda that Russian operatives may have spread during the run-up to Britain’s 2016 referendum on EU

membership.

Some British lawmakers had complained that the world’s largest social media network had done only a limited search for evidence that Russians manipulated the network and interfered with the referendum debate.

Russia denies meddling in Britain’s vote to exit the European Union, known as Brexit, or in the 2016 U.S. elections.

Facebook, Twitter Inc and Alphabet Inc’s Google and YouTube have been under intense pressure in Europe and the United States to stop nations from using tech services to meddle in another country’s elections, and to investigate when evidence of such meddling arises.

Facebook’s new search in Britain will require the company’s security experts to go back and analyze historical data, Simon Milner, Facebook’s UK policy director, wrote in a letter on Wednesday to Damian Collins, chair of the British parliament’s Digital, Culture, Media and Sport Committee.

“We would like to carry out this work promptly and estimate it will take a number of weeks to complete,” Milner wrote.

Facebook said in December that it had found just 97 cents worth of advertising by Russia-based operatives ahead of Britain’s vote to leave the EU. Its analysis, though, involved only accounts linked to the Internet Research Agency, a suspected Russian propaganda service.

Collins last month described Facebook’s initial Brexit-related search as inadequate, and said on Wednesday he welcomed the company’s latest response.

“They are best placed to investigate activity on their platform,” he said in a statement. “I look forward to seeing the results of this investigation, and I’m sure we will want to question Facebook about this when we know the outcome.”

Facebook told U.S. lawmakers last year that it had found 3,000 ads bought by suspected Russian agents posing as Americans and seeking to spread divisive messages in the United States about race, immigration and other political topics.

In France last year, Facebook suspended 30,000 accounts in the days before the country’s presidential election to try to stop the spread of fake news, misinformation and spam.

Apple is planning to build another corporate campus and hire 20,000 workers during the next five years as part of a $350 billion commitment to the U.S. economy.

The pledge announced Wednesday is an offshoot from the sweeping overhaul of the U.S. tax code championed by President Donald Trump and approved by Congress last month.

 

Besides dramatically lowering the standard corporate tax rate, the reforms offer a one-time break on cash being held overseas.

 

Apple plans to take advantage of that provision to bring back more than $250 billion in offshore cash, generating a tax bill of roughly $38 billion.

 

The Cupertino, California, company says it will announce the location of a second campus devoted to customer support later this year.

Twitter may notify users whether they were exposed to content generated by a suspected Russian propaganda service, a company executive told U.S. lawmakers Wednesday.

The social media company is “working to identify and inform individually” its users who saw tweets during the 2016 U.S. presidential election produced by accounts tied to the Kremlin-linked Internet Research Army, Carlos Monje, Twitter’s director of public policy, told the U.S. Senate Commerce, Science and Transportation Committee.

A Twitter spokeswoman did not immediately respond to a request for comment about plans to notify its users.

Facebook Inc in December created a portal where its users could learn whether they interacted with accounts created by the Internet Research Agency.

Both companies and Alphabet’s YouTube appeared before the Senate committee on Wednesday to answer lawmaker questions about how their efforts to combat the use of their platforms by violent extremists, such as the Islamic State.

But the hearing often turned its focus to questions of Russian propaganda, a vexing issue for internet firms who spent most of the past year responding to a backlash that they did too little to deter Russians from using their services to anonymously spread divisive messages among Americans in the run-up to the 2016 U.S. elections.

U.S. intelligence agencies concluded Russia sought to interfere in the election through a variety of cyber-enabled means to sow political discord and help President Donald Trump win. Russia has repeatedly denied the allegations.
