Attorneys for Twitter, Facebook and Google on Tuesday told U.S. lawmakers that Russian entities used their platforms to sow discord and disinformation during the 2016 U.S. presidential campaign, but downplayed the magnitude of those efforts.

“Foreign actors used fake accounts to place ads in Facebook and Instagram that reached millions of Americans over a two-year period,” Facebook General Counsel Colin Stretch said, testifying before a Senate Judiciary subcommittee. “Many of these ads and posts are inflammatory. Some are downright offensive.”

Sean Edgett, Twitter’s acting general counsel, said the company studied all tweets posted from Sept. 1 to Nov. 15, 2016, and found that election-related content posted by automated Russian troll accounts “was comparatively small.” He said the Russian troll accounts made up “around 1/100th of a percent of total Twitter accounts” during the time studied.

“Twitter believes that any activity of that kind — regardless of magnitude — is unacceptable and we agree we must do better to prevent it,” he said.

Twitter has taken action against the suspected Russian trolls, suspending 2,752 accounts and implementing new dedicated teams “to enhance the quality of the information our users see,” Edgett said.

Facebook, meanwhile, said it would hire more people to vet and, when necessary, remove content, and verify and publish the identities of election advertisers.

Bipartisan legislation has been introduced in the Senate requiring some of the very steps technology giants say they are implementing on their own.

“These platforms are being used by people who wish us harm and wish to undercut our way of life,” said Republican Senator Lindsey Graham of South Carolina.

“It shouldn’t be news to anyone that Russia interfered in the election,” said California Democratic Senator Dianne Feinstein. “What is really staggering and hard to fully comprehend is how easily and successfully they turned modern technologies to their advantage.”

The social media attorneys said Russian trolling campaigns consistently sought to rile up Americans, first in a way damaging to Democratic presidential nominee Hillary Clinton. After the election, they said, Russian efforts appeared aimed at sowing doubts about the legitimacy of Republican Donald Trump’s victory at the polls — a point seized upon by Republican Senator Chuck Grassley of Iowa.

“Russia does not have loyalty to a political party in the United States; their goal is to divide us and discredit our democracy,” Grassley said.

Representatives from the same social media companies testify Wednesday before the House and Senate Intelligence Committees.

Apple is offering a nifty way to unlock its new iPhone X — just stare at it.

Face ID, Apple’s name for its facial-recognition technology, replaces the fingerprint sensor found on other models.

How well does it work — not just technically, but in everyday use? After all, it’s much easier to align your finger with the sensor than to align your face with the phone.

The iPhone X costs about $1,000 — $300 more than the iPhone 8. Advance orders began this past Friday, and Apple is now giving delivery times of five to six weeks. Apple says it will have limited supplies at stores for same-day pickup on Friday, but you’ll have to get there early.

Better face detection

Many rival Android phones already use facial-recognition technology. Samsung also has an unlock feature that scans your iris. But the systems can be tripped with something as simple as eyeglasses.

While Android largely bases its match on a two-dimensional camera shot of you, the iPhone X goes 3-D. During setup, the iPhone guides you to rotate your head so it gets a more complete picture of you — analyzing some 30,000 points on your face, to be specific. So if you’re wearing glasses, the iPhone can still recognize you using other parts of your face. Same goes for wearing a hat.

And Apple’s system continually learns. Each time you use your face to unlock the phone, it automatically keeps tabs on small changes, such as growing a mustache or simply getting older. With Android, you have to go into the settings to teach the phone’s face recognition to get better.

There are limits. If you shave your beard, it’s too big of a change for the iPhone X to be sure it’s you. You’ll need a passcode, but the phone should remember you the next time .

Recognizing you

I tested the iPhone X against Samsung’s iris scanner on the Galaxy Note 8 and face systems on Google’s Pixel 2 and LG’s V30 phones. V30 improves upon the standard Android technology in asking you to turn your head slightly during the setup, though in practice the Pixel was far better at recognition.

Only the iPhone and the Pixel recognized me with standard eyeglasses — important, as I expect the same performance with or without spectacles. That said, Face ID unlocked with just one of the two sunglasses I tried; the other was too big.

Costumes and disguises also challenged Face ID. A Santa hat was OK, but a Santa beard wasn’t. Nor did it like funny glasses and a fake nose. Winter clothing was fine, as long as the scarf wasn’t covering too much of my face.

Face ID worked better than expected in bright sunlight — not every time, but enough to be satisfying. It also worked in the dark, thanks to the use of infrared sensors rather than just the standard camera. That’s important when you wake up in the middle of the night and must absolutely check Facebook or Tinder. For those keeping score, the Pixel worked in sunlight, but not in the dark; it’s the reverse for Samsung. Samsung also worked with the Santa beard, as it’s focused on your eyes.

The iPhone also unlocked after getting a haircut.

I didn’t try to fool the iPhone into unlocking with someone else’s face. I’m sure hackers will spend the coming weeks trying. Apple says Face ID could be unreliable with twins and other siblings who look like you, as well as for children under 13 — though young children don’t really need a $1,000 phone. Give them a $200 iPod Touch — or better yet, a book to read.

No more fingerprint

The home button is gone to increase screen space. Others that have done this have moved the fingerprint scanner to the back. Apple ditches it completely, so Face ID is the only alternative to a passcode. The Olsen twins, among others, will face a hardship.

It’s also tougher to check Facebook during a meeting without getting busted by the boss. You can casually unlock a phone with your fingerprint under the table. It’s much more conspicuous to stare at a screen, especially because your face should ideally be 6 to 10 inches (15 to 25 centimeters) away.

Besides unlocking the phone, you can use Face ID to confirm app purchases and log into banking apps. You can also confirm Apple Pay transactions. You don’t have to twist your head awkwardly for facial authorization while the phone is laying sideways on a payment terminal, either. With the iPhone X, you authorize Apple Pay before tapping. It was much faster than fingerprint when paying for lunch.

Bottom line is Face ID works fairly well — though keeping the fingerprint option would have been nice.

There’s a short but not-so-simple question facing Vietnam’s technology startup fans: Now, what?

The communist country was not immune to the startup craze that swept the globe, but much of the early period was spent talking about tech and all the local potential. In what could be called the next phase of the craze, Vietnam now hopes to go beyond just talking. The focus now is on getting entrepreneurs to deliver on their pitches and meet concrete benchmarks, whether that’s to turn a profit, expand overseas, or find “exits” for their businesses, such as through acquisitions.

At a basic level, Vietnam has what’s needed to be a place prime for startups. Citizens have high literacy rates and math proficiency, which eases the path to creating an army of programmers for the economy. The country also has a balance that combines, on the one hand, a large consumer market on par with those of Thailand and the Philippines, and on the other hand, a lower level of development with high growth rates on par with those of Laos and Cambodia. And the low cost of things like wages and Internet plans allows people to establish companies at minimal expense.

But these are only ingredients, not, so far, action toward a modern culture of enterprise.

“Vietnam usually does copy-paste,” said Lam Tran, CEO of the startup WisePass, adding that locals should move past the model of copying a business idea from a foreign country and pasting it into the domestic market. “We don’t know how to internationalize.”

WisePass, an app that connects monthly subscribers to bar and restaurant deals, launched in Ho Chi Minh City with plans to cover seven countries in the near future.

Taking advantage of cross-border ties is one effective, increasingly popular strategy, startup aficionados say. For one thing, Vietnam has a huge postwar diaspora, known as Viet Kieu, who help connect the Southeast Asian country to investors, advisers, and developers abroad. For another, the tech scene inside the border is more cosmopolitan than ever.

To give one example, the Vietnam Innovative Startup Accelerator (VIISA) has invested in 11 companies for the second batch of what it calls “graduates.” All have domestic links, but have partners operating in locales as disparate as Ukraine, South Korea and France.

Sangyeop Kang, investment officer at VIISA partner Hanwha Investment, said he’s “delighted about the diversity” of this sophomore batch.

“The foreign teams were able to expand their business in Vietnam, while helping Vietnamese companies with global insights,” Kang said. “This is a step forward for the ecosystem.”

In a sign of official interest, the government has a carve-out for startups in its Law on Supporting Small and Medium-Sized Enterprises, which will take effect Jan. 1. The law offers young companies support with co-working spaces, technical equipment, intellectual property training, and low interest rates, among other things.

To do more than copy and paste, new businesses are contemplating how to outfit themselves for Vietnam. The startup But Chi Mau, for instance, makes games that tap into the unquenchable thirst for education, while MarketOi deploys motorbike drivers to let customers customize their food deliveries.

“The question is how to differentiate ourselves,” MarketOi founder Germain Blanchet said, before proceeding to answer that question: “This is with flexibility.”

Billionaire Elon Musk has released a photograph of a tunnel he’s building under a Los Angeles suburb to test a novel transportation concept for a system that would move people underground in their personal cars rather than by subway trains.

The founder of SpaceX and Tesla tweeted during the weekend that the tunnel was 500 feet so far and should be 2 miles long in three or four months.

In August, the Hawthorne City Council granted a permit allowing an underground extension of approximately 2 miles from SpaceX property, crossing under a corner of the municipal airport and beneath city streets to a point about a mile east of Los Angeles International Airport.

Musk also tweeted that hopefully in a year or so the tunnel would stretch along the Interstate 405 corridor from LAX to U.S. Highway 101 in the San Fernando Valley, which would require approval from other governments. That span is about 17 miles.

Musk has complained about what he called “soul-destroying” Los Angeles traffic. He added The Boring Company to his ventures, acquired a tunnel-boring machine that had been used in a San Francisco Bay Area project and put it down a shaft in a SpaceX parking lot this year.

Hawthorne council document say the “Test Tunnel for Zero Emission Subterranean Transportation” has an exterior diameter of 13.5 feet (4.1 meters) and an interior diameter of approximately 12 feet (3.6 meters) and will run as deep as 44 feet (13.4 meters) beneath the surface.

“When the project is completed, the Test Tunnel would house a ‘skate’ system that would be tested to prove the viability for transporting pedestrians or personal vehicles. The concept is that a vehicle would be drive on to the skate, the engine would be turned off and the vehicle and its passenger would be transported from one end of the Test Tunnel to the other,” the August resolution said.

“The Test Tunnel project would involve SpaceX engineers repeatedly testing and experimenting with personal vehicle types suitable for placement on the skates; refinement of the design and technology; and general data collection on performance, durability, and application. No public use of the Test Tunnel would occur, and no people would be occupying vehicles located on the skates as the skates are tested within the tunnel,” it added.

Construction was expected to take about five months to complete, the resolution said. Musk has maintained that tunneling can be accomplished much more rapidly than occurs with current methods.

The plan allows the city to request that the tunnel be filled in when testing is complete.

Musk has also advocated another transportation concept called the “hyperloop,” a network of nearly airless tubes that would speed special capsules over long distances at up to 750 mph (1,207 kph), using a thin cushion of air, magnetism and solar power. SpaceX has recently hosted competitions by development teams on a test track built at its headquarters.

On Monday, SpaceX conducted its 16th Falcon 9 rocket launch of the year, carrying a South Korean satellite into space from Florida’s Kennedy Space Center. The rocket’s first-stage booster scored another successful landing aboard a floating platform in the Atlantic.

A rare bird has landed at the University of Michigan: a two-legged robot named “Cassie” that researchers hope could be the forerunner of a machine that one day will aid search-and-rescue efforts.

Cassie — whose name is derived from the cassowary, a flightless bird similar to an ostrich — stands upright on legs with backward-facing knees. The biped that weighs about 66 pounds (29.94 kilograms) may not have feathers or a head, but she is attached to a short torso that holds motors, computers and batteries and is able to walk unassisted on rough and uneven terrain.

Cassie, which stands a bit over 3.25 feet (1 meter) at full leg extension, was built by Albany, Oregon-based Agility Robotics and purchased by Michigan researchers using grant money from the National Science Foundation and Toyota Research Institute. Although other institutions have acquired similar models, Michigan’s team is excited to use its version to put Michigan Robotics’ cutting-edge programming to the test, said Jessy Grizzle, director of Michigan Robotics.

“This stuff makes our old math look like child’s play,” Grizzle said.

Although there is considerable excitement about Cassie and the potential she represents, certain real-world applications are still a bit out of reach.

Search-and-rescue “is a hard problem and serves as a template for ‘unsolved problems in robotics,’ which is one of the reasons you see it pop up so much when robotics companies talk about applications,” said Agility Robotics CEO Damion Shelton, who added that it is “difficult to even speculate” when a robot could be used for such a purpose.

Other applications will be launched sooner, according to Shelton, who said a robot capable of walking around the perimeter of an industrial site taking 3-D scans is no more than two years away from becoming reality.

For now, Grizzle and some of his students are putting Cassie through her paces on and around Michigan’s Ann Arbor campus. During a recent a stroll on a pedestrian walkway, Cassie ambled on a grassy, sloped surface, then took a serious tumble and did a face-plant on the concrete.

“Well, I think that’s the end” of the test, Grizzle said, as Cassie lay in a heap on the ground, slightly nicked and scratched but no worse for wear.

The programs Grizzle and his students tested “are version 1.0,” he said.

“They are simple algorithms to make sure that we understand the robot. We will now focus on implementing our super-cool latest stuff,” Grizzle said.

The World Economic Forum’s human rights council report issued on Monday, warns that tech companies might risk tougher regulations by governments to limit freedom of speech if they do not stem the publishing of violent content by Islamic State and the spread of misinformation.

The report urged tech companies to employ thorough monitoring on their services, and “assume a more active self-governance rule,” recommending that tech firms must apply more rigorous rules.

This report comes before the three tech giants Facebook, Twitter and Google, testify before a U.S. congressional committee in November about using their platforms for spreading political misinformation during the 2016 presidential elections.

The use of tech platforms and tools has helped the Islamic State spread its agenda and attract recruits. Digital propaganda motivated more than 30,000 people to journey thousands of miles to join IS, according to a report published by Wired, a magazine published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics.

“ISIS’s supporters embraced new social media platforms and encrypted communications tools to compensate for law enforcement and platform owner actions against ISIS since June 2014,” the Institute for the Study of War said in its report “The Virtual  Caliphate.”

Silicon Valley tech companies convened last August with representatives from the tech industry, government and non-governmental organizations in the first Global Internet Forum to Counter Terrorism. The forum was formed by Facebook, Microsoft, Twitter and YouTube.

The meeting focused on how participating parties can cooperate to block the spread of terrorism and violent extremism using tech platforms and services.

In the past year, social media companies edited and updated their user guidelines to address such sensitive topics as extremism and terrorism, death, war and sexual abuse.

In August 2016, Twitter announced that it suspended 360,000 accounts for violating the company’s prohibition on violent threats and the promotion of terrorism. Twitter added that although there is no “one magic algorithm for identifying terrorist content on the internet, they will continue to utilize other forms of technology and expanded its partnerships with organizations working to counter violent extremism (CVE) online.”

Last August, Google’s YouTube announced joining efforts with more than 15 additional expert NGOs and institutions to help the company better identify content that is being used to radicalize and recruit extremists.

“We’ll soon be applying tougher treatment to videos that aren’t illegal but have been flagged by users as potential violations of our policies on hate speech and violent extremism,” YouTube said.

In a speech for the Global Coalition on March 22 in Washington D.C., Secretary of State Rex Tillerson said: “We must break ISIS’s ability to spread its message and recruit new followers online. A digital caliphate must not flourish in the place of a physical one.”

“We must fight ISIS online as aggressively as we would on the ground,” Tillerson said.

People are big polluters, on the land, in the sea and even in outer space, that can include anything from a hammer that floats away from the space station, to radiation from a nuclear weapons test in the atmosphere.

“This can range from little chips of paint all the way up to spent rocket bodies and things like that,” said Dan Baker, director of the Laboratory of Atmosphere and Space Physics at the University of Colorado, Boulder. “We’ve been trying to figure out how can we most effectively eliminate this debris without causing more of a problem.”

Space debris travels so fast, even an orbiting chip of paint can poke a hole in a satellite. But Baker says something tinier, and natural, is a bigger hazard: It’s the highly charged “killer electrons” of the magnetized zone above the earth called The Van Allen Belts.

“We’ve observed them to cause very significant problems for spacecraft,” Baker said.

Electro-magnetic planetary blanket

The doughnut-shaped Van Allen Belts around our planet protect life on earth from solar winds and cosmic rays. But their highly energetic charged particles can damage the circuitry in space stations, weather satellites and other machines that travel through that region of space.

Baker notes that “killer electrons” can also come from some human activities, like the atmospheric testing of nuclear weapons.

“Back in the 1950s and especially in the 1960s, there were nuclear explosions that put huge amounts of radiation into space that caused many satellites to ‘die’ because of radiation damage,” he said. “And if that were to happen today, we know that there are over 1,400 satellites operating in space around the earth and all of those could be subject to very severe consequences.”

Most nations adhere to treaties that prohibit atmospheric weapon testing. But Baker says that’s no guarantee.

“What is worrisome to us from a political standpoint today is that there are nations, for example, North Korea and others, that may be thinking once again, and who may not be adherent to such treaties, that this might be an interesting way to mess with modern technology,” Baker said.

Mysterious space shield

Radiation particles in the Van Allen Belts already “mess” with modern technology. So when satellites must spend time in that region, they are built with thicker materials. That armor makes them heavier, and more expensive. Fortunately, spacecraft and satellites that orbit just under the Van Allen Belts don’t need this heavy shielding. Baker says that’s because, at the lower edge of the Van Allen Belts, the killer electrons abruptly stop.

He compares it to the shields that protected Captain Kirk’s ship, the Enterprise, from phasers and asteroids on Star Trek.

Scientists have known for years that something here on the earth creates an invisible bubble that clears killer electrons from the lower edge of the Van Allen Belts. Just what makes that shield has been a mystery.

But recently, Baker’s teams figured out its source. The “bubble maker” is very low frequency radio transmissions, also known as VLF. Militaries use VLF to communicate with submarines underwater. It turns out those radio waves also travel up, through the atmosphere, to the Van Allen Belts.

“So the VLF bubble is made up of these intense waves. These waves act to sort of scatter and scrub the inner part of the Van Allen Belts,” Baker said, admitting, “I would prefer that we not be messing with nature. However, in this particular case I would say that there is some evidence that this is beneficial.”

John Bonnell, a researcher at the University of California Berkeley’s Space Sciences Lab, agrees that VLF “pollution” is probably benign, and he points to the high-energy radiation emitted by lightning bolts as evidence.

“We’ve had natural clearing of the radiation Belts with lightning, for as long as we’ve had lightning. So in essence, you’ve had a long-running experiment that you can look at and say, ‘Well, if we’re going to do things on sort of a sporadic basis, whereas lightning’s been doing it daily for hundreds of millions of years, the likelihood of there being a bad side effect is pretty minimal,'” he said.

Bonnell says that discovering a man-made way to clear killer electrons from the Van Allen Belt does not mean we will soon create “shields up” devices that use magnetics or radio transmissions. At least, he says, we’re not making them yet.

“It’s a fascinating possibility and it’s a fascinating technology that could enable us in the future, to explore more of the solar system with people, with robots. And so it’s definitely something that people pick away at slowly over time,” he said.

Bonnell says scientists, engineers and astronomers have teamed up to make amazing discoveries about how to study, and travel through, outer space. And while the future shape of space exploration is a mystery, our new understanding about the man-made “pollution” that shields satellites may be an important part of it.
