Plastic: If It’s Not Keeping Food Fresh, Why Use It?

All, News, Technology

The food industry uses plastic to wrap its products in many places around the world. Plastic manufacturers say that keeps produce and meat fresh longer, so less goes bad and is thrown away. But, according to a new European study, while the annual use of plastic packaging has grown since the 1950s, so has food waste. Faiza Elmasry has the story. Faith Lapidus narrates.

Zuckerberg Under Pressure to Face EU Lawmakers Over Data Scandal

All, News, Technology

Facebook Inc’s Chief Executive Mark Zuckerberg came under pressure from EU lawmakers on Wednesday to come to Europe and shed light on the data breach involving Cambridge Analytica that affected nearly three million Europeans.

The world’s largest social network is under fire worldwide after information about nearly 87 million users wrongly ended up in the hands of the British political consultancy, a firm hired by Donald Trump for his 2016 U.S. presidential election campaign.

European Parliament President Antonio Tajani last week repeated his request to Zuckerberg to appear before the assembly, saying that sending a junior executive would not suffice.

EU Justice Commissioner Vera Jourova, who recently spoke to Facebook Chief Operating Officer Sheryl Sandberg, said Zuckerberg should heed the lawmakers’ call.

“This case is too important to treat as business as usual,” Jourova told an assembly of lawmakers.

“I advised Sheryl Sandberg that Zuckerberg should accept the invitation from the European Parliament. (EU digital chief Andrius) Ansip refers to the invitation as a measure of rebuilding trust,” she said.

Facebook did not respond to a request for comment. Zuckerberg fielded 10 hours of questions over two days from nearly 100 U.S. lawmakers last week and emerged largely unscathed. He will meet Ansip in San Francisco on Tuesday.

Another European lawmaker Sophia in’t Veld echoed the call from her colleagues, saying that the Facebook CEO should do them the same courtesy.

“I think Zuckerberg would be well advised to appear at the Parliament out of respect for Europeans,” she said.

Lawmaker Viviane Reding, the architect of the EU’s landmark privacy law which will come into effect on May 25, giving Europeans more control over their online data, said the right laws would bring back trust among users.

 

Iran Bans Government Bodies from Using Foreign Message Apps

All, News, Technology

Iran’s presidency has banned all government bodies from using foreign-based messaging apps to communicate with citizens, state media reported Wednesday, after economic protests organized through such apps shook the country earlier this year.

Chief among those apps is Telegram, used by over 40 million Iranians for everything from benign conversations to commerce and political campaigning. Iranians using Telegram, which describes itself as an encrypted message service, helped spread the word about the protests in December and January.

Telegram channels run on behalf of Iran’s Supreme Leader, Ayatollah Ali Khamenei, and Vice President Eshaq Jahangiri were already shut down Wednesday.

A report on the website of Iran’s state television broadcaster said the ban affected all public institutions. It was not clear if the ban applied to civil servants outside of work hours. The report did not elaborate on penalties for violating the ban.

Last month, officials said Iran would block Telegram for reasons of national security in response to the protests, which saw 25 people killed and nearly 5,000 reportedly arrested.

Authorities temporarily shut down Telegram during the protests, though many continued to access it through proxies and virtual private networks.

The move against Telegram suggests Iran may try to introduce its own government-approved, or “halal,” version of the messaging app, something long demanded by hard-liners. Already, Iran heavily restricts internet access and blocks social media websites like Facebook and Twitter.

Iran has said foreign messaging apps can get licenses from authorities to operate if they transfer their databases into the country. Privacy experts worry that could more easily expose users’ private communications to government spying.

Khamenei, however, has stressed that invading people’s privacy is religiously forbidden.

Iran’s move also comes after a Russian court on Friday ordered Telegram to be blocked after the company refused to share its encryption data with authorities.

Telegram CEO Pavel Durov responded to the ruling by writing on Twitter: “Privacy is not for sale, and human rights should not be compromised out of fear or greed.”

Russia Admits to Blocking Millions of IP Addresses

All, News, Technology

The chief of the Russian communications watchdog acknowledged Wednesday that millions of unrelated IP addresses have been frozen in a so-far futile attempt to block a popular messaging app.

Telegram, the messaging app that was ordered to be blocked last week, was still available to users in Russia despite authorities’ frantic attempts to hit it by blocking other services.

The row erupted after Telegram, which was developed by Russian entrepreneur Pavel Durov, refused to hand its encryption keys to the intelligence agencies. The Russian government insists it needs them to pre-empt extremist attacks but Telegram dismissed the request as a breach of privacy.

Alexander Zharov, chief of the Federal Communications Agency, said in an interview with the Izvestia daily published Wednesday that Russia is blocking 18 networks that are used by Amazon and Google and which host sites that they believe Telegram is using to circumvent the ban.

Countless Russian businesses – from online language schools to car dealerships – reported that their web services were down because of the communication watchdog’s moves to bloc networks.

Internet experts estimate that Russian authorities have blocked about 16 million IP addresses since Monday, affecting millions of Russian users and businesses.

In the interview, Zharov admitted that the authorities have been helplessly trying to block Telegram and had to shut down entire networks, some of which have over half a million IP addresses that are used by unrelated, “law-abiding companies,” he said.

Russia’s leading daily Vedomosti in Wednesday’s editorial likened the communications watchdog’s battle against Telegram, affecting millions of users of other web-services, to warfare.

“The large-scale indiscriminate blocking of foreign IP addresses in Russia in order to close the access to the messaging app Telegram is unprecedented and bears resemblance to carpet bombings,” the editorial said.

Zharov also indicated that Facebook could be the next target for the government if it refuses to comply with Russian law.

Authorities previously insisted that Facebook store its Russian users’ data in Russia but has not gone through with its threats to block Facebook if it refuses to comply.

Zharov said authorities will check before the end of the year if the company is complying with its demands and warned that if it does not, “then, obviously, the issue of blocking will arise.”

Elsewhere in Moscow, a court on Wednesday sentenced a member of the punk collective Pussy Riot, who spent nearly two years in prison for a protest in Russia’s main cathedral, to 100 hours of community work for a protest against the Telegram blocking. Maria Alekhina and a dozen activists were throwing paper planes outside the communications watchdog’s office on Monday.

Cambridge Analytica ex-CEO Refuses to Testify in UK

All, News, Technology

Cambridge Analytica’s ex-CEO, Alexander Nix, has refused to testify before the U.K. Parliament’s media committee, citing British authorities’ investigation into his former company’s alleged misuse of data from millions of Facebook accounts in political campaigns.

Committee Chairman Damian Collins announced Nix’s decision a day before his scheduled appearance but flatly rejected the notion that he should be let off the hook, saying Nix hasn’t been charged with a crime and there are no active legal proceedings against him.

“There is therefore no legal reason why Mr. Nix cannot appear,” Collins said in a statement. “The committee is minded to issue a formal summons for him to appear on a named day in the very near future.”

Nix gave evidence to the committee in February, but was recalled after former Cambridge Analytica staffer Christopher Wylie sparked a global debate over electronic privacy when he alleged the company used data from millions of Facebook accounts to help U.S. President Donald Trump’s 2016 election campaign. Wylie worked on Cambridge Analytica’s “information operations” in 2014 and 2015.

Wylie has also said the official campaign backing Britain’s exit from the European Union had access to the Facebook data.

Cambridge Analytica has previously said that none of the Facebook data it acquired from an academic researcher was used in the Trump campaign. The company also says it did no paid or unpaid work on the Brexit campaign. The company did not respond to requests for comment from The Associated Press on Tuesday.

The Information Commissioner’s Office said Tuesday that it had written to Nix to “invite him” to be interviewed by investigators. The office is investigating Facebook and 30 other organizations over their use of data and analytics.

“Our investigation is looking at whether criminal and civil offences have been committed under the Data Protection Act,” the office said in a statement.

Nix’s refusal to appear comes as the seriousness of the British inquiry becomes more evident.

Facebook has said it directed Cambridge Analytica to delete all of the data harvested from user accounts as soon as it learned of the problem.

But former Cambridge Analytica business development director Brittany Kaiser testified Tuesday that the U.S. tech giant didn’t really try to verify Cambridge Analytica’s assurances that it had done so.

“I find it incredibly irresponsible that a company with as much money as Facebook … had no due diligence mechanisms in place for protecting the data of U.K. citizens, U.S. citizens or their users in general,” she said.

Kaiser suggested that the number of individuals whose Facebook data was misused could be far higher than the 87 million acknowledged by the Silicon Valley giant.

In an atmosphere where data abuse was rife, Kaiser told lawmakers she believed the leadership of the Leave.EU campaign had combined data from members of the U.K. Independence Party and customers from two insurance companies, Eldon Insurance and GoSkippy Insurance. The data was then sent the University of Mississippi for analysis.

“If the personal data of U.K. citizens who just wanted to buy car insurance was used by GoSkippy and Eldon Insurance for political purposes, as may have been the case, people clearly did not opt in for their data to be used in this way by Leave.EU,” she said in written testimony to the committee.

Leave.EU’s communications director, Andy Wigmore, called Kaiser’s statements a “litany of lies.”

It is how the data was used that alarms some members of the committee and has captured the attention of the public.

An expert on propaganda told the committee Monday that Cambridge Analytica used techniques developed by the Nazis to help Trump’s presidential campaign, turning Muslims and immigrants into an “artificial enemy” to win support from fearful voters.

University of Essex lecturer Emma Briant, who has for a decade studied the SCL Group – a conglomerate of companies, including Cambridge Analytica – interviewed company founder Nigel Oakes when she was doing research for a book. Oakes compared Trump’s tactics to those of Nazi leader Adolf Hitler in singling out Jews for reprisals.

“Hitler attacked the Jews, because … the people didn’t like the Jews,” he said on tapes of the interview conducted with Briant. “He could just use them to . leverage an artificial enemy. Well that’s exactly what Trump did. He leveraged a Muslim.”

More Than 100 Parts for NASA’s Orion Capsule to Be 3-D Printed

All, News, Technology

More than 100 parts for U.S. space agency NASA’s deep-space capsule Orion will be made by 3-D printers, using technology that experts say will eventually become key to efforts to send humans to Mars.

U.S. defense contractor Lockheed Martin, 3-D printing specialist Stratasys, and engineering firm PADT have developed the parts using new materials that can withstand the extreme temperatures and chemical exposure of deep-space missions, Stratasys said Tuesday.

“In space, for instance, materials will build up a charge. If that was to shock the electronics on a space craft, there could be significant damage,” Scott Sevcik, Vice President Manufacturing Solutions at Stratasys told Reuters.

3-D printing, or additive manufacturing, has been used for making prototypes across a range of industries for many years, but is being increasingly eyed for scale production.

The technology can help make light-weight parts made of plastics more quickly and cheaply than traditional assembly lines that require major investments into equipment.

“But even more significant is that we have more freedom with the design … parts can look more organic, more skeletal,” Sevcik said.

Stratasys’ partner Lockheed Martin said the use of 3-D printing on the Orion project would also pay off at other parts of its business.

“We look to apply benefits across our programs — missile defense, satellites, planetary probes, especially as we create more and more common products,” said Brian Kaplun, additive manufacturing manager at Lockheed Martin Space.

Orion is part of NASA’s follow-up program to the now-retired space shuttles that will allow astronauts to travel beyond the International Space Station, which flies about 260 miles (420 km) above Earth.

The agency’s European counterpart, ESA, has suggested that moon rock and Mars dust could be used to 3-D print structures and tools, which could significantly reduce the cost of future space missions because less material would need to be brought along from Earth.

Toyota to Launch ‘Talking’ Vehicles in US in 2021

All, News, Technology

Toyota Motor Corp. plans to start selling U.S. vehicles that can talk to each other using short-range wireless technology in 2021, the Japanese automaker said on Monday, potentially preventing thousands of accidents annually.

The U.S. Transportation Department must decide whether to adopt a pending proposal that would require all future vehicles to have the advanced technology.

Toyota hopes to adopt the dedicated short-range communications systems in the United States across most of its lineup by the mid-2020s. Toyota said it hopes that by announcing its plans, other automakers will follow suit.

The Obama administration in December 2016 proposed requiring the technology and giving automakers at least four years to comply. The proposal requires automakers to ensure all vehicles “speak the same language through a standard technology.”

Automakers were granted a block of spectrum in 1999 in the 5.9 GHz band for “vehicle-to-vehicle” and “vehicle to infrastructure” communications and have studied the technology for more than a decade, but it has gone largely unused. Some in Congress and at the Federal Communications Commission think it should be opened to other uses.

In 2017, General Motors Co began offering vehicle-to-vehicle technologies on its Cadillac CTS model, but it is currently the only commercially available vehicle with the system.

Talking vehicles, which have been tested in pilot projects and by U.S. carmakers for more than a decade, use dedicated short-range communications to transmit data up to 300 meters, including location, direction and speed, to nearby vehicles.

The data is broadcast up to 10 times per second to nearby vehicles, which can identify risks and provide warnings to avoid imminent crashes, especially at intersections.

Toyota has deployed the technology in Japan to more than 100,000 vehicles since 2015.

The U.S. National Highway Traffic Safety Administration (NHTSA) said last year the regulation could eventually cost between $135 and $300 per new vehicle, or up to $5 billion annually but could prevent up to 600,000 crashes and reduce costs by $71 billion annually when fully deployed. 

NHTSA said last year it has “not made any final decision” on requiring the technology, but no decision is expected before December.

Last year, major automakers, state regulators and others urged U.S. Transportation Secretary Elaine Chao to finalize standards for the technology and protect the spectrum that has been reserved, saying there is a need to expand deployment and uses of the traffic safety technology.
