Years of limited oversight and unchecked growth have turned Facebook into a force with incredible power over the lives of its 2 billion users. But the social network has also given rise to unintended social consequences, and they’re starting to catch up with it:

House and Senate panels investigating Russian interference in the 2016 elections have invited Facebook, along with Google and Twitter, to testify this fall. Facebook just agreed to give congressional investigators 3,000 political ads purchased by Russian-backed entities, and announced new disclosure policies for political advertising
Facebook belatedly acknowledged its role purveying false news to its users during the 2016 campaign and announced new measures to curb it. Founder and CEO Mark Zuckerberg even apologized, more than 10 months after the fact, for calling the idea that Facebook might have influenced the election “pretty crazy.”
The company has taken flack for a live video feature that was quickly used to broadcast violent crime and suicides; for removing an iconic Vietnam War photo for “child pornography” and then backtracking; and for allegedly putting its thumb on a feature that ranked trending news stories.

Facebook is behind the curve in understanding that “what happens in their system has profound consequences in the real world,” said Fordham University media-studies professor Paul Levinson. The company’s knee-jerk response has often been “none of your business” when confronted about these consequences, he said.

Moving fast, still breaking things

That response may not work much longer for a company whose original but now-abandoned slogan — “move fast and break things” — sometimes still seems to govern it.

Facebook has, so far, enjoyed seemingly unstoppable growth in users, revenue and its stock price. Along the way, it has also pushed new features on to users even when they protested, targeted ads at them based on a plethora of carefully collected personal details, and engaged in behavioral experiments that seek to influence their mood.

“There’s a general arrogance — they know what’s right, they know what’s best, we know how to make better for you so just let us do it,” said Notre Dame business professor Timothy Carone, who added that this is true of Silicon Valley giants in general. “They need to take a step down and acknowledge that they really don’t have all the answers.”

Hands-off Facebook

Facebook generally points to the fact that its policies prohibit misuse of its platform, and that it is difficult to catch everyone who tries to abuse its platform. When pressed, it tends to acknowledge some problems, offer a few narrowly tailored fixesand move on.

But there is a larger question, which is whether Facebook has taken sufficient care to build policies and systems that are resistant to abuse.

Facebook declined to address the subject on the record, although it pointed to earlier public statements in which Zuckerberg described how he wants Facebook to be a force for good in the world. The company also recently launched a blog called “Hard Questions” that attempts to address its governance issues in more depth.

But Sheryl Sandberg, the company’s No. 2 executive, offered an unexpected perspective on this question in a recent apology. Facebook “never intended or anticipated” how people could use its automated advertising to target ads at users who expressed anti-Semitic views. That, she wrote, “is on us. And we did not find it ourselves — and that is also on us.”

As a result, she said the company will tighten its ad policies to ensure such abuses don’t happen again.

Having enough clean drinking water has been a challenge in many parts of the world, whether it’s a place where water is scarce or abundant. The World Health Organization finds 3 in 10 people globally still lack safe drinking water at home.

The U.S. Department of Energy has just announced it is providing up to $15 million in funding for projects to develop solar desalination technology to create freshwater at a lower cost. Even before the announcement, researchers had been working on better ways to desalinate water.

“We can take any quality of water that we’re starting with and we can turn it into any quality of water that we desire at the end, and the only real challenge or limitation has to be overcome is how much does it cost and how much energy does it take to go from here to here,” said Eric Hoek, co-founder and Chief Executive Officer of Water Planet Inc.

Cheaper energy

Water treatment plants are largely driven by electricity. A cheaper source of energy is the sun.

“What’s changed in the last five to 10 years, solar has gotten cheap,” Hoek said.

“The only reason that that has not taken over the world at this point is that it’s still intermittent. The sun goes up and it comes down. You have power when it’s up and don’t when it’s down. What you need to make that a continuous base load is you need batteries, which you can charge up during the day, discharge at night, and the cost of batteries is still currently pretty high.”

Household system

Qilin Li at Rice University is building a desalination system that uses solar energy with broad drinking water applications for “individual households or small communities that live in remote locations, especially those who don’t have access to municipal water supply, don’t have a stable supply of electricity. This technology can be an ideal technology,” Li said.

Her solar-powered desalination system can “also benefit megacities in developing countries that don’t have the extensive water and power infrastructure we enjoy here in developed countries, and that kind of relief perhaps in not providing all the water for the whole city, but can relieve some of their need or dependency on the power grid,” Li said.

The goal of Li’s system is to make it modular and cost efficient so it could either meet the needs of a small household or a large community.

Li and her team created a reactor to distill water using heat from the sun. Water turns into vapor, goes through a porous membrane and becomes pure water. Li says a low cost coating on the membrane developed at Rice University makes this unique.

“So it (membrane) harvests the sunlight, converts the photon energy in the sunlight to heat highly efficiently to generate water vapor, and it also serves a separation function to keep the contaminants on the dirty side of the membrane and only allow pure water vapor to go through,” Li said.

Waste heat

The sun is not the only low cost source of energy. Amy Childress’ lab at the University of Southern California (USC) looks at how waste heat that comes from manufacturing can be used as a resource.

“With waste heat you’re going to have cycles and spikes. We’ve gone out to the field, measured waste heat at an industrial site. We come back. We plug that into our system, so that we can repeat that waste heat curve over and over and watch the response of membranes to the waste heat,” said Childress, who directs USC’s Civil and Environmental Engineering Department’s environmental engineering program.

Her lab looks at how waste heat would impact the longevity and properties of a membrane.

Childress says the work in her lab will be helpful in the development of better membranes.

Filters in demand

There is high demand for membranes that help produce clean water. Water Planet’s PolyCera® membrane used to treat wastewater, is finding broader applications.

“We have a lot of interest now around the world, not just in industrial wastewater, but we’re actually making point-of-use under-the-sink water filters for applications in India, in China and here in the U.S. We’re making membranes that are being tested now for deployment offshore in sea water desalination to produce drinking water in barges and in platforms,” Hoek said.

With nearly 30 percent of the world’s population lacking safe drinking water at home, researchers will continue to work on harnessing free energy to clean water.

A long-running effort to build one of the world’s largest telescopes on a mountain sacred to Native Hawaiians is moving forward after a key approval Thursday, reopening divisions over a project that promises revolutionary views into the heavens but has drawn impassioned protests over the impact to a spiritual place.

Hawaii’s land board granted a construction permit for the $1.4 billion Thirty Meter Telescope atop the state’s tallest mountain, called Mauna Kea, but opponents likely would appeal the decision to the state Supreme Court. Protesters willing to be arrested were successful in blocking construction in the past.

“For the Hawaiian people, I have a message: This is our time to rise as a people,” said Kahookahi Kanuha, a protest leader. “This is our time to take back all of the things that we know are ours. All the things that were illegally taken from us.”

No construction soon

Telescope officials don’t have any immediate construction plans and will consider its next steps, said Scott Ishikawa, a project spokesman. Officials previously have said they want to resume building in 2018.

“In moving forward, we will listen respectfully to the community in order to realize the shared vision of Mauna Kea as a world center for Hawaiian culture, education and science,” TMT International Observatory Board Chairman Henry Yang said in a statement.

Richard Ha, a Native Hawaiian farmer who supports the project, urged opponents to avoid confrontation.

“The possibility of getting the best telescope in the world … I don’t feel is the right battle to fight,” he said. “It will hurt our own people.”

While opponents say constructing the telescope will desecrate Mauna Kea, supporters tout the instrument’s ability to provide long-term educational and economic opportunities.

“This was one of the most difficult decisions this board has ever made,” state Board of Land and Natural Resources Chairwoman Suzanne Case said in a statement about the 5-2 decision.

Plans for the project date to 2009, when scientists selected Mauna Kea after a five-year around-the-world campaign to find the ideal site for what telescope officials said “will likely revolutionize our understanding of the universe.”

The project won a series of approvals from Hawaii, including a permit to build on conservation land in 2011. Protesters blocked attempts to start construction. Then in 2015, the state Supreme Court invalidated the permit, saying the board’s approval process was flawed, and ordered the project to go through the steps again.

​Protests from the beginning

Protests disrupted a groundbreaking in 2014 and intensified after that. Construction stopped in 2015 after 31 demonstrators were arrested for blocking the work.

A second attempt to restart construction a few months later ended with more arrests and crews retreating.

Mehana Kihoi said being arrested while praying on the mountain was one of the most traumatic experiences of her life. She started going there to help heal from domestic violence, Kihoi told the land board earlier this month.

“For years, I carried grief and pain … until I went to the mauna,” she said, using the Hawaiian word for mountain.

Culture over money

Kanuha, a protest leader, dismissed the millions that telescope officials have paid toward educating youth on the Big Island in science, technology, engineering and math. So far, $3.5 million has been paid into the educational fund, even while the project’s construction permit was invalid.

That money isn’t the answer to improving the lives of Native Hawaiian youth, Kanuha said. Revitalization of language and culture through Hawaiian-focused education is what’s important, he said.

A group of Native Hawaiian telescope supporters formed a group called Perpetuating Unique Educational Opportunities. Some members had been against the telescope in the past, said the group’s attorney, Lincoln Ashida.

“We believe that with increased opportunities for children, that results in stronger families, which in turn benefits our community,” Ashida told the board.

A group of universities in California and Canada make up the telescope company, with partners from China, India and Japan. The instrument’s primary mirror would measure 98 feet (30 meters) in diameter. Compared with the largest existing visible-light telescope in the world, it would be three times as wide, with nine times more area.

Mauna Kea, a dormant volcano, has been the first choice, telescope officials said, calling it the best location in the world for astronomy. Its summit provides a clear view of the sky for 300 days a year, with little air and light pollution. They selected an alternate site in Spain’s Canary Islands if the telescope couldn’t be built in Hawaii.

Around the world, women are using technology to overcome barriers in education and employment. Getting online, however, remains a challenge for many women in developing countries.  

In the United States, the issue isn’t access to technology, but the lack of women pursuing technical careers.

Beginning Oct. 4 in Orlando, Florida, female leaders will discuss the digital gender divide at Voice of America’s town hall at the Grace Hopper Celebration of Women in Computing, the world’s largest gathering of women technologists.

“The tech ecosystem has, sadly, not been welcoming to women,” said Y-Vonne Hutchinson, founder of ReadySet, a diversity consultancy that works in the tech industry.

Women struggle for access

Globally, women struggle for access to technology. Proportionally, the number of women using the internet is 12 percent lower, compared to men. In the least developed countries, only one in seven women is using the internet, compared to one in five men, according to a 2017 study.

“The digital divide is basically this phenomenon that some people have more access to digital technology than others or use it more than others, which is actually an unavoidable thing,” said Martin Hilbert, an assistant professor at the University of California, Davis. “Every innovation that comes to society doesn’t form uniformly from heaven. It diffuses through society.”

In a study of 25 countries in Africa and Latin America, Hilbert noted that if he adjusted for income, education and job opportunities, more women than men were online. “The fact that they turn up less is because they have less access to money, education and work opportunities,” he said.

Cultural barriers

Women also face some cultural barriers, said Nighat Dad, executive director of the Digital Rights Foundation in Pakistan.

The biggest reason she sees for why women are not getting online is what she describes as “the cultural norms or the family values.”

“The middle-class families or lower-class families think that access to computers or access to technologies is a boy’s basic rights and not the girls’ because the girls don’t need it,” she said.

Tara Chklovski, founder and chief executive of Iridescent, an organization that works to promote girls in tech worldwide, said her organization has worked with local partners to overcome barriers.

“There’s a country in Africa, where it is not cool for girls to own phones, only middle-age men,” she said. “When we came in and said we want to teach girls, they said why don’t you teach boys or why don’t you teach these men. We had to work for many years to address barriers.”

Women ‘held to higher bar’

In the U.S., there is a lively debate over why women continue to lag behind men in the tech industry. Women make up about 20 percent of companies’ technical workforce and about the same in leadership roles, said Caroline Simard, research director at the Clayman Institute of Gender Research at Stanford University.

“Often women are held to a higher bar to be successful,” said Simard. “They have to work harder to prove the same amount of competence.”

And when it comes to venture capitalists, who finance the startup ecosystem, not many are women.

“I joke in my profession, I don’t have to stand in line for a bathroom,” said Kate Mitchell, a partner at Scale Venture Partners. “Five to 10 percent of investing partners are women, depending what study you look at.”

VOA town hall

Women in tech roles inside a firm are at a higher risk of leaving the profession mid-career. Some say they felt they never belonged.

At VOA’s town hall at the Grace Hopper Celebration, leaders in technology will talk about what it will take to continue to close the digital gender divide.

“For the first time in history, technology can really help girls have a strong voice and help us have a society that has equality,” said Chklovski.

Drones will help deliver toothbrushes, deodorant and smartphones to Swiss homes this fall as part of a pilot project, the first of its kind over a densely populated area.

Drone firm Matternet, based in Menlo Park, California, said Thursday it’s partnering on the Zurich project with Mercedes-Benz’s vans division and Swiss e-commerce startup Siroop. It’s been approved by Switzerland’s aviation authority.

Matternet CEO Andreas Raptopoulos says the drones will take items from a distribution center and transport them between 8 to 16 kilometers to awaiting delivery vans. The van drivers then bring the packages to homes. Raptopoulos says drones will speed up deliveries, buzzing over congested urban streets or natural barriers like Lake Zurich.

The pilot comes as Amazon, Google and Uber have also been investing in drone delivery research.

Would you buy a car that sprayed soothing odors when you’re stuck in rush-hour traffic? Or how about a robot that smells like a human being?

Scientists say that new technology means we will soon be using devices like these in our everyday lives. At this month’s British Science Festival in Brighton, researchers from Britain’s University of Sussex offered a demonstration of the technology that could be just around the corner.

The 3D animations of Virtual Reality have become commonplace. Now scientists have created virtual worlds that even smell like the real thing. When users open a virtual door and step into a new world, in this case into a rainforest, diffusers spray the appropriate scent for added authenticity.

Immersive experience

“It is a really immersive experience that you have because you’re exploring this environment and you have smells that correspond with it,” festival visitor Suzanne Fisher-Murray told VOA.

Smell technology has been tried before, famously in the United States with Smell-O-vision movies in the 1960s. Multisensory researcher Emanuela Maggioni of the University of Sussex says it’s on the cusp of a comeback.

“The connection with emotions, memories, and the potential to use the sense of smell, the odors, under the threshold of our awareness — it is incredible what we can do with technology,” Maggioni said.

And not just for entertainment. In another corner of the room, a driving simulator has been fitted with a scent diffuser.

“In this demonstration, we wanted to deliver the smell of lavender every time the driver exceeds the speed limit. We chose lavender because it’s a very calming smell,” co-researcher Dmitrijs Dmitrenko said.

Scent and human behavior

Scientists are experimenting with using scent instead of audible or visual alerts on mobile phones. Businesses already are using scent to influence customers’ behavior.

“Not only for marketing in stores, so creating the logo brand. But on the other side, you can create and stimulate impulse buying. So you’re in a library and you smell coffee and actually you are unconsciously having the need to drink a coffee,” Maggioni said.

She adds that scent is vital in human interactions — for example, when men smell tears, levels of testosterone are reduced and they show more empathy. That physiological reaction can be applied to new technology.

“In the interaction with robots — how we can build trust with robots if the robots smell like us,” Maggioni said.

It portends an exciting, and perhaps for some, daunting future. Scientists say the sense of smell, until now largely unexploited, is about to stimulated by the march of technology.

Twitter is going to allow some users to super size their tweets.

The company just announced it’s doubling the length of a tweet from 140 characters to 280 characters for “a small group” of users.

Twitter did not say whether President Trump (@realDonaldTrump), an avid tweeter, will be one of those allowed to post longer tweets, but said the feature is going out to a “random sample,” so it’s certainly possible.

Japanese, Korean and Chinese users are excluded from the expanded tweets because the characters allow people to say a lot more with fewer characters.

Ever think about hacking into the U.S. government’s data system? Wanna try?

If you can develop a network signature for an intrusion detection system (detect hacking), or perform forensic analysis of a compromised endpoint (detect hacking before it collapses the system), the National Security Administration wants you to try.

Registration is open for the 2017 Codebreaker Challenge. The contest asks college students to use reverse engineering or the ability to take apart code and fix from scratch a fictional break-in of a government data system. The scenario helps the Department of Homeland Security disarm an improvised explosive device using cybersecurity skills to prevent civilian casualties.

“Reverse engineering is a crucial skill for those involved in the fight against malware, advanced persistent threats, and similar malicious cyber activities,” the NSA website says. “As the organization tasked with protecting U.S. government national security information systems, NSA is looking to develop these skills in university students (and prospective future employees).”

Each year, undergraduate and grad students who compete to master six tasks will receive a small token of appreciation from the NSA for being among the first 50 finishers, and possible credit from the student’s college or university.

Setup a test instance of the system (Task 0)
Analyze suspicious network traffic (Task 1)
Develop a network signature for an intrusion detection system (Task 2)
Analyze critical system components for vulnerabilities (Tasks 3 and 4)
Perform forensic analysis of a compromised endpoint (Task 5)
Craft an exploit for the botnet server and devise a strategy to clean the infected endpoints (Task 6)

Registration for students with a valid email address ending in .edu started September 15 and continues until December 31.

This year, some have gotten close, but no one has completed all six tasks, so far, says the Codebreaker Challenge website. As of September 25, students from 335 colleges and universities have tried.

The most participants in 2016 came from Georgia Institute of Technology in Atlanta, with 149 students taking the challenge, but only five completing all six tasks, which also ranks first for most successful participants.

In addition to Georgia Tech, three students from Carnegie Mellon University in Pittsburgh, completed every task; as well as three from the U.S. Naval Academy in Annapolis, Md. one from University of Maryland, College Park, one from Naval Postgraduate School in Monterey, Calif., one from Lesley University in Cambridge, Mass., and one from Williams College in Williamstown, Mass.

Last year, 3,325 students from 481 colleges and universities attempted to finish all six tasks; only 15 students were successful. Robert Xiao from Carnegie Mellon University in Pittsburgh completed every task in just under 18 hours, which was nearly two and a half days quicker than the next fastest finisher.

“I find computer security to be a fascinating subject, and I was really lucky to be accepted at Carnegie Mellon, which has an excellent computer security reputation,” said Xiao, who was born and raised in Canada.

Carnegie Mellon ranks in the top 20 for cybersecurity schools in the U.S. and is known nationwide as a pipeline for future computer security experts. Xiao is on the Plaid Parliament of Pwning (PPP) hacking team at CMU and says the team, “participates in worldwide computer security competitions and does very well.”

That’s not an understatement. In fact, the PPP hacking team has won eight straight virtual capture-the-flag competitions at New York University’s Cyber Security Awareness Week and won the World Series of Hacking college competition four of the past five years.

The 2017 Codebreaker Challenge “is very challenging and covers a wide range of subjects … but it takes a lot of time and effort at first,” Xiao says. “Don’t get discouraged if it seems too hard, that’s totally normal at first.”

Xiao is doing a Ph.D. in what he calls “human-computer interaction,” in which he wants to merge computer security and human interaction.

“The subject of ‘usable’ human-friendly security is really important and only a handful of people are thinking really hard about it,” he said. Essentially, Xiao wants to expand the use of computer security for those who might not be the most adept at using computers; in other words, make computer security easier for the everyday user.

Instructions and storyline for this year’s challenge can be found on the Codebreaker Challenge website.

Digital devices designed to monitor the wearer’s health in much greater detail than current models will need regulatory approval, and Apple, Fitbit and seven other companies will take part in a program to speed the approval process, the U.S. health regulator said Tuesday.

The firms will take part in a program that could make it faster for digital health devices to come to market by requiring less information to be sent to regulators ahead of time, the U.S. Food and Drug Administration said.

Current devices, like the Apple Watch or Fitbit Blaze, measure things like motion and heart rate. But to take further measurements like blood oxygen or glucose, future devices might full under regulatory review. That review can take months or years, which is far slower than the pace of software updates from most technology firms.

Because of the potential for lengthy reviews, consumer technology companies have been reluctant to wade directly into territory regulated by the FDA. Apple, for example, has tended to partner with existing health researchers and companies such as DexCom Inc, a conventional medical device firm, for uses of their products that involve regulatory oversight.

But under President Donald Trump, the FDA has been moving to relax some of its requirements. The FDA in July created a pilot program that would pre-certify certain companies so that they have to submit less information before marketing a product.

The initial participants in the pilot program also included Samsung Electronics, Alphabet’s Verily biotech unit, Johnson & Johnson and Swiss biotech firm Roche AG, among others. The FDA said in a statement it was also considering whether companies in the pilot program “may not have to submit a product for premarket review in some cases.”

“Our method for regulating digital health products must recognize the unique and iterative characteristics of these products,” FDA Commissioner Scott Gottlieb said in the statement.

One major difference in the pilot program from existing regulations is that it will evaluate companies based on how well their software-design systems work, rather than looking at each product and its accompanying software individually.

“We are hopeful this will allow us to accelerate FDA regulated features and software development, bringing new capabilities that could positively impact health outcomes to market more quickly,” Fitbit CEO James Park said in a statement.

The days of Twitter limiting messages to 140 characters, a signature of the social network since its launch in 2006, may be numbered.

Twitter said on Tuesday that it would begin a test with a random sample of users allowing them to send tweets that are as long as 280 characters, double the existing cap, in most languages around the world.

The San Francisco-based company has stood by its short messages as a defining characteristic – like chirps from a bird, which is the company logo – even as users found ways around the limit, such as posting photos of text.

In a blog post on Tuesday, Twitter said its emphasis on brevity would never change but that it had been wondering whether people could express themselves easily enough, hurting the service’s popularity.

“Trying to cram your thoughts into a Tweet – we’ve all been there, and it’s a pain,” Twitter project manager Aliza Rosen and senior software engineer Ikuhiro Ihara said in the post.

The employees acknowledged some users may have an “emotional attachment” to the current limit.

News reports in January 2016 said that Twitter was running internal tests for longer tweets and considering a limit as high as 10,000 characters.

Though Twitter is ubiquitous in media because of frequent use by U.S. President Donald Trump and many celebrities, the company has struggled financially. For the second quarter, it reported a loss of $116 million and zero growth in the number of users, at 328 million people. Facebook Inc has 2 billion users.

A higher character limit was inspired by how people use Twitter when writing in Chinese, Japanese and Korean, the company said.

Characters in those languages can often express more than Roman characters can, meaning those users already, in effect, have a higher limit. They also use Twitter more often.

“In all markets, when people don’t have to cram their thoughts into 140 characters and actually have some to spare, we see more people Tweeting,” the two employees wrote.

The test of 280 characters will run for an unspecified number of weeks in all languages except Chinese, Japanese and Korean, Twitter said. The company declined to say how many people would be included in the test.

The 140-character limit originated from the use of SMS text messages. Twitter’s founders, including Chief Executive Jack Dorsey, wanted a limit just below the SMS cap of 160 characters.

A coalition of businesses including Amazon, Google and General Motors has agreed to give $300 million to boost K-12 computer science programs across the U.S.

Internet Association CEO Michael Beckerman announced Tuesday that the private-sector contribution will come in over the next five years. Beckerman led a panel discussion at a downtown Detroit high-rise that featured President Donald Trump’s daughter and adviser Ivanka Trump.

Her visit to Detroit came a day after the president announced a plan to spend at least $200 million annually on competitive grants so schools can broaden access to computer science education.

“Knowing how to code is really foundational toward success in any industry, not just tech narrowly defined,” Ivanka Trump said.

Just before Ivanka Trump arrived on stage, Beckerman announced the private-sector contribution.

Amazon, Facebook, Google, Microsoft and Salesforce.org are giving $50 million apiece; Lockheed Martin is promising $25 million; Accenture is committing more than $10 million; and General Motors and Pluralsight have pledged $10 million toward the effort. Additionally, Detroit-based Quicken Loans announced that it will work to make sure that 15,000 Detroit Public Schools students receive computer science training.

Ivanka Trump said it is crucial that young people, especially girls and racial minorities, learn how to write computer code and study computer science.

“We have to do better. We are going to do better, and this is a giant leap forward in that direction,” she said during the panel discussion, which also included Dan Gilbert, chairman of Quicken Loans; Hadi Partovi, CEO of Code.org; Rob Acker, CEO of Salesforce.org; and Marillyn Hewson, CEO of Lockheed Martin.

Gilbert said teaching schoolchildren computer science “isn’t one of these things where maybe this will work.

“This is the answer. This is flat-out the answer,” said Gilbert, who also owns the Cleveland Cavaliers of the NBA.
