It’s Not Technology That’s Disrupting Our Jobs

The insecure nature of work is a result of decisions by corporations and policymakers.


Excerpt:

But this narrative is wrong. The history of labor shows that technology does not usually drive social change. On the contrary, social change is typically driven by decisions we make about how to organize our world. Only later does technology swoop in, accelerating and consolidating those changes.

This insight is crucial for anyone concerned about the insecurity and other shortcomings of the gig economy. For it reminds us that far from being an unavoidable consequence of technological progress, the nature of work always remains a matter of social choice. It is not a result of an algorithm; it is a collection of decisions by corporations and policymakers.

Experiencing heritage through VR

Researchers at IIT-H working on narrating historical incidents in digital form
The city’s history is taking a giant digital leap, from fading pages to virtual reality headgears, promising to add dimensions to the experience of “experiencing” heritage.

Researchers at the Design Department of Indian Institute of Technology-Hyderabad are working on conserving the city’s heritage through virtual reality (VR), giving narration a digital but a life-like feel. Stories being told, at the moment of those from the Qutb Shahi era, aim to teleport one to the time in which the historical incidents occurred.

A New Way to Detect Breast Cancer

For poorer people in India and many other countries, a computer engineer has found a way to detect breast cancer without radiation.


Excerpt:

He knew that whatever device he designed would have to be usable by community health care workers, the backbone of most developing countries’ health systems. It would also have to be portable and battery operated. And screening would have to affordable and painless.

Using a new ceramic sensor technology developed at Drexel University’s School of Biomedical Engineering, Science and Health Systems in Philadelphia to detect subtle variations in breast tissue, Mr. Shah and his colleague Matthew Campisi developed iBreastExam, a battery-operated wireless machine that records variations in breast elasticity. It’s hand-held and allows health care workers to perform breast examinations in five minutes, anywhere. Painless and radiation-free, it provides results just a few minutes after the exam through a mobile app, which also records patients’ data

Amazon’s Plan to Reach 500 Million Indians: Speak Their Language

BANGALORE, India — Only 10 percent of India’s 1.3 billion people know English. Yet most of the country’s e-commerce services have been offered only in English, closing off online shopping to the vast majority of people here.

Now Amazon is aiming to break through that language barrier. The e-commerce giant on Tuesday offered a hearty “namaste” to this country’s half a billion Hindi speakers by making its local website and apps available in India’s most popular language. Users of the India site or app will be able to choose Hindi as their preferred language, much as American users can choose Spanish.

Tiny Device Is a ‘Huge Advance’ for Treatment of Severe Heart Failure

A clip used to repair damaged heart valves sharply reduced deaths among patients with a grim prognosis.


Excerpt:

But on Sunday, researchers reported that a tiny clip inserted into the heart sharply reduced death rates in patients with severe heart failure.

In a large clinical trial, doctors found that these patients also avoided additional hospitalizations and described a drastically improved quality of life with fewer symptoms.

The results, reported at a medical meeting in San Diego and published simultaneously in the New England Journal of Medicine, were far more encouraging than heart specialists had expected.

Special report: The new global race to space

The big picture: From Dubai to the U.S., Tokyo to Moscow, Tel Aviv to Beijing and more, billionaires, privateers and political leaders are vying to land on the Moon, colonize Mars, mine asteroids — and just get off the Earth. "Whatever we have evolved into hundreds and thousands of years from now, we'll look at these decades as when the human race moved off the planet," said Peter Diamandis, chairman of the X-Prize Foundation.

Jeff Hawkins Is Finally Ready to Explain His Brain Research

REDWOOD CITY, Calif. — In the global race to build artificial intelligence, it was a missed opportunity.

Jeff Hawkins, a Silicon Valley veteran who spent the last decade exploring the mysteries of the human brain, arranged a meeting with DeepMind, the world’s leading A.I. lab.

Scientists at DeepMind, which is owned by Google’s parent company, Alphabet, want to build machines that can do anything the brain can do. Mr. Hawkins runs a little company with one goal: figure out how the brain works and then reverse engineer it.

The meeting, set for April at DeepMind’s offices in London, never happened. DeepMind employs hundreds of A.I. researchers along with a team of seasoned neuroscientists. But when Mr. Hawkins chatted with Demis Hassabis, one of the founders of DeepMind, before his visit, they agreed that almost no one at the London lab would understand his work.

The space race is dominated by new contenders

Private businesses and rising powers are replacing the cold-war duopoly


Some 4,500 satellites circle Earth, providing communications services and navigational tools, monitoring weather, observing the universe, spying and doing more besides. Getting them there was once the business of the superpowers’ armed forces and space agencies. Now it is mostly done by companies and the governments of developing countries.

Drones

Pies in the skies


The use of drones to make household deliveries has not taken off as quickly as expected. But with operators gaining experience, regulators have begun to relax the rules, especially away from built-up areas. People living in parts of Reykjavik can get restaurant food delivered to their backyards. A drone in Singapore will soon ferry supplies to ships moored offshore. Residents of central Manhattan may have to wait a while longer

Why Doctors Reject Tools That Make Their Jobs Easier

From the thermometer’s invention onward, physicians have feared—incorrectly—that new technology would make their jobs obsolete

I want to tell you about a brouhaha in my field over a “new” medical discipline three hundred years ago. Half my fellow doctors thought it weighed them down and wanted nothing to do with it. The other half celebrated it as a means for medicine to finally become modern, objective, and scientific. The discipline was thermometry, and its controversial tool a glass tube used to measure body temperature called a thermometer.

This all began in 1717, when Daniel Fahrenheit moved to Amsterdam and offered his newest temperature sensor to the Dutch physician Herman Boerhaave.* Boerhaave tried it out and liked it. He proposed using measurements with this device to guide diagnosis and therapy.

The promise and peril of gene drives

A new genetic-engineering technology should be used with care


Excerpt:

The extermination that the creatures in Mr Simoni’s lab are designed to take part in is less viscerally gratifying—but far more consequential. The mosquitoes are being fitted with a piece of dna called a gene drive. Unlike the genes introduced into run-of-the-mill genetically modified organisms, gene drives do not just sit still once inserted into a chromosome. They actively spread themselves, thereby reaching more and more of the population with each generation. If their effect is damaging, they could in principle wipe out whole species.

To engineer an extinction is quite a step. But it is not unprecedented. In 1980 Variola, the smallpox virus, was exterminated from the wild. That marked the eradication of a disease which, from 1900 to 1980, killed around 300m people. If gene drives like those being worked on at Imperial and elsewhere were to condemn to a similar fate the mosquitoes that spread malaria, a second of humankind’s great scourges might be consigned to history.

It need not stop with malaria. Gene drives can in principle be used against any creatures which reproduce sexually with short generations and aren’t too rooted to a single spot. The insects that spread leishmaniasis, Chagas disease, dengue fever, chikungunya, trypanosomiasis and Zika could all be potential targets. So could creatures which harm only humankind’s dominion, not people themselves. Biologists at the University of California, San Diego, have developed a gene-drive system for Drosophila suzukii, an Asian fruitfly which, as an invasive species, damages berry and fruit crops in America and Europe. Island Conservation, an international environmental ngo, thinks gene drives could offer a humane and effective way of reversing the damage done by invasive species such as rats and stoats to native ecosystems in New Zealand and Hawaii.

Needless to say, the enthusiasm is not universal. Other environmental groups worry that it will not prove possible to contain gene drives to a single place, and that species seen as invasive in one place might end up decimated in other places where they are blameless, or even beneficial. If drives are engineered into species that play a pivotal but previously unappreciated ecological role, or if they spread from a species of little ecological consequence to a close relative that matters more, they could have damaging and perhaps irreversible effects on ecosystems.

We Need an FDA For Algorithms

UK mathematician Hannah Fry on the promise and danger of an AI world.


In the introduction to her new book, Hannah Fry points out something interesting about the phrase “Hello World.” It’s never been quite clear, she says, whether the phrase—which is frequently the entire output of a student’s first computer program—is supposed to be attributed to the program, awakening for the first time, or to the programmer, announcing their triumphant first creation.

Perhaps for this reason, “Hello World” calls to mind a dialogue between human and machine, one which has never been more relevant than it is today. Her book, called Hello World, published in September, walks us through a rapidly computerizing world. Fry is both optimistic and excited—along with her Ph.D. students at the University of College, London, she has worked on many algorithms herself—and cautious. In conversation and in her book, she issues a call to arms: We need to make algorithms transparent, regulated, and forgiving of the flawed creatures that converse with them.

I reached her by telephone while she was on a book tour in New York City.

Don’t Be Scared of Killer Robots

We should be thinking more about how much A.I. has changed our lives already, and the future of human-algorithm collaboration.


When it comes to the future of artificial intelligence, we seem to be stuck in a loop. We tell the same stories about A.I. over and over again: society is destroyed (the “Terminator” movies), the machines emulate and replace us (“Ex Machina”), the machines become gods pulling the strings (“The Matrix”). This is a dangerous way to think about A.I., because the stories we tell influence the decisions we make about how such systems should operate.

None of the three scenarios I just described represents a future in which we would want to live. They are all trajectories in which superintelligent machines simply leave us behind. If we spend all of our time looking over our shoulders for killer robots, that means we are not looking ahead to discern the outcomes we might actually want. A study of A.I. representations in film and television by Christopher Noessel underscores the problem: We have lots of stories about the power and the duplicitous nature of A.I., but almost none exploring what he calls the “Untold A.I.” themes: accountability, effective policy and broad literacy around these technologies.

To thrive in the era of intelligent machines, we need to expand our thinking. Instead of worrying about godlike super-machines, we should tell better stories about all the everyday ways A.I. is already changing the world.

Members of USA Jamat explore frontiers of science and technology

This month, The.Ismaili is focussing on the theme of Science and Technology. Today, we will explore the numerous ways that members of the Jamat in the United States participate in and contribute to the fields of Science, Technology, Engineering, and Mathematics (STEM).

"....what are the subjects which will be necessary tomorrow? Is the developing world going to continue in this deficit of knowledge? Or are we going to enable it to move forwards in to new areas of knowledge? My conviction is that we have to help these countries move into new areas of knowledge. And therefore, I think of areas such as the space sciences, such as the neurosciences. There are so many new areas of inquiry which, unless we make an effort to share globally, we will continue to have vast populations around the world who will continue in this knowledge deficit."
-Mawlana Hazar Imam, Investiture Ceremony as a Member of the Lisbon Academy of Sciences, Lisbon, 8 May 2009

How Plato Foresaw Facebook’s Folly

Technology promises to make easy things that, by their intrinsic nature, have to be hard.


Excerpt:

The story of the wildly exaggerated promises and damaging unintended consequences of technology isn’t exactly a new one. The real marvel is that it constantly seems to surprise us. Why?

Part of the reason is that we tend to forget that technology is only as good as the people who use it. We want it to elevate us; we tend to degrade it. In a better world, Twitter might have been a digital billboard of ideas and conversation ennobling the public square. We’ve turned it into the open cesspool of the American mind. Facebook was supposed to serve as a platform for enhanced human interaction, not a tool for the lonely to burrow more deeply into their own isolation.

It’s also true that Facebook and other Silicon Valley giants have sold themselves not so much as profit-seeking companies but as ideal-pursuing movements. Facebook’s mission is “to make the world more open and connected.” Tesla’s goal is “to accelerate the world’s transition to sustainable energy.” Google’s mantra was “Don’t Be Evil,” at least until it quietly dropped the slogan earlier this year.

But the deeper reason that technology so often disappoints and betrays us is that it promises to make easy things that, by their intrinsic nature, have to be hard.

Brain implant lets paralyzed people turn thoughts into text

Participants sent texts, streamed music and browsed the web on unmodified devices


Three people paralyzed from the neck down have been able to use unmodified computer tablets to text friends, browse the internet and stream music, thanks to an electrode array system called BrainGate2. The findings could have a major impact on the lives of those affected by neurologic disease, injury, or limb loss.

The system uses an array of micro-electrodes implanted into the brain which decode, in real time, the neural signals associated with the intention to move a limb. The three people involved in the trial had electrode grids implanted over part of their motor cortex -- the area of the brain that helps control movement -- which picked up neural activity indicating they were thinking about moving a cursor on the screen. Those patterns were then sent to a virtual mouse that was wirelessly paired to the tablet.

Chinese Scientist Claims to Use Crispr to Make First Genetically Edited Babies

The researcher, He Jiankui, offered no evidence or data to back up his assertions. If true, some fear the feat could open the door to “designer babies.”


Ever since scientists created the powerful gene editing technique Crispr, they have braced apprehensively for the day when it would be used to create a genetically altered human being. Many nations banned such work, fearing it could be misused to alter everything from eye color to I.Q.

Now, the moment they feared may have come. On Monday, a scientist in China announced that he had created the world’s first genetically edited babies, twin girls who were born this month.

The researcher, He Jiankui, said that he had altered a gene in the embryos, before having them implanted in the mother’s womb, with the goal of making the babies resistant to infection with H.I.V. He has not published the research in any journal and did not share any evidence or data that definitively proved he had done it.

But his previous work is known to many experts in the field, who said — many with alarm — that it was entirely possible he had.

Editing Babies? We Need to Learn a Lot More First

An experiment in China to alter the genomes of embryos in vitro, then implant them in the mother, is a step too far.


Sooner or later it was bound to happen: A rogue scientist in China claims to have edited a gene in two human embryos and implanted them in the mother’s womb, resulting in the birth of genetically altered twin girls. We’re no longer in the realm of science fiction. If true, this hacking of their biological operating instructions, which they will pass on to their children and generations to come, is a dangerous breach of medical ethics and responsible research and must be condemned.

This is not to say that medicine won’t someday employ gene-editing technologies in similar ways. But that time has not arrived. There are still too many risks, too many unknowns, about tinkering with our heritable genetic blueprints.

The ‘Next America’

How do we govern in the age that will begin with the 2020 election?


Excerpt:

This Next America will raise a whole web of new intertwined policy, legal, moral, ethical and privacy issues because of changes in technology, demographics, the environment and globalization that are reaching critical mass.

Where do I start? A good place is with 5G — fifth-generation wireless systems. With the two telecom giants Verizon and AT&T now beginning to deploy 5G technology across the country, the metabolism of business, entertainment, education and health care will dramatically accelerate in the Next America, beginning around … 2020.

Getting the most from artificial intelligence and machine learning — like deploying self-driving vehicles — requires quickly transmitting massive amounts of data with very low latency. We will have that capacity in the Next America. With 5G, a Hollywood movie that now takes six or seven minutes to download onto your iPad will take six or seven seconds and microsensors in your shirt will gather intelligence and broadcast vital signs to your doctor.

As AT&T notes in one of its 5G ads, “Think of this as the next frontier in untethering, giving you the ability to take the ultrafast experience you have in your home or business with you virtually anywhere.’’

It could be as revolutionary as the internet.

But it will require all kinds of new regulations to govern applications from self-driving cars to drone delivery systems to robots that will work as security guards and home health aides.

The Deadly Soul of a New Machine

Bots, artificial intelligence and social media algorithms are shaping the fate of humanity at a startling pace. At what point is control lost and the creations take over? How about now?


Excerpt:

But it’s not too much of a reach to see Flight 610 as representative of the hinge in history we’ve arrived at — with the bots, the artificial intelligence and the social media algorithms now shaping the fate of humanity at a startling pace.

Like the correction system in the 737, these inventions are designed to make life easier and safer — or at least more profitable for the owners. And they do, for the most part. The overall idea is to outsource certain human functions, the drudgery and things prone to faulty judgment, while retaining master control. The question is: At what point is control lost and the creations take over? How about now?

It’s a Briefcase! It’s a Pizza Box! No, It’s a Mini Satellite

Orbiting instruments are now so small they can be launched by the dozens, and even high school students can build them.


Recently, officials in California announced that the Camp Fire, the deadliest wildfire in the state’s history, had been fully contained. The achievement was made possible through the hard work of firefighters on the ground, with some help from above: a swarm of tiny, orbiting satellites that represent the next phase of the space age.

The satellites are operated by Planet Labs, a company in San Francisco that runs the world’s largest fleet of Earth-observing satellites. Its craft number around 140. All of them carry cameras and telescopes. In size, most rival a loaf of bread.

As a group, the satellites can view the same spot on the ground once or even twice a day. Until now, commercial satellites could observe a location only weekly or monthly, if at all. The quicker pace enables the close monitoring of rapid environmental change, including fires, floods, volcanic eruptions, earthquakes, hurricanes and the effects of such events on urban areas.

“You can’t fix what you can’t see,” said Will Marshall, the company’s chief executive.

Earth’s magnetic field is mysteriously acting up, pushing North Pole towards Siberia

Earth’s magnetic field, the basis for modern global navigation systems, is constantly in some state of flux. However, it now seems to be going haywire, pushing the North Pole closer to Siberia, and no one’s sure why.
The field changes as the molten metals surrounding the earth’s solid iron core churn and flow, creating electric currents and a corresponding magnetic field. As a result, the magnetic poles tend to shift slightly as a matter of course.

However, researchers don’t know what’s causing the magnetic field to now move so quickly.

The north magnetic pole sped across the International Date Line last year at a rate of 55 km per year, more than three times as fast as it moved before the mid-1990s. Now located in the Eastern Hemisphere, it’s moving away from Canada and approaching Siberia.

Scientists think a high-speed jet of liquid iron under Canada could be responsible for the pole’s movement, weakening the magnetic field below and allowing Siberia to draw over the pole, Nature reports.

“The location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia,” University of Leeds geomagnetist Phil Livermore told a recent American Geophysical Union meeting. “The Siberian patch is winning the competition.”

In general, the World Magnetic Model (WMM) is updated at five-year intervals to ensure modern navigation keeps up with the changes in the Earth’s magnetic field. It was due to be reconfigured next in 2020, but was so out-of-whack by 2018 that a more urgent update was needed.

How the Internet has changed us

The digital age has changed our lives in many parts of the world, inextricably tethering them to the Internet for the simplest to the most sophisticated of tasks. In the first of a new series of articles on how to use digital media safely, Altaf Jiwa outlines the role that the Internet and social media have come to play in our daily lives.

From finding our way to unknown destinations, to finding like-minded people, communities or untapped markets; digital platforms and applications have created a wealth of possibilities and conveniences for many. Google, Amazon, Netflix, Uber — the list goes on and on. While this has in many ways simplified day-to-day life and created great advancement in fields such as education, healthcare, and business, it has not come without a cost. As Jerome Lawrence has said, “Progress has never been a bargain. You have to pay for it.”

How many of us start and end our days cradling a smartphone? That meal we’re about to eat, a concert or new city, that enviable relationship, some of us document every detail so that we can share it virtually. Experts say the social media ‘Like’ triggers a chemical reaction in the brain resulting in a real, physiological high which is fundamentally the reason we keep going back to it; the more we get it, the more we want it. But being overly connected can cause psychological issues as well, such as distraction, narcissism, expectation of instant gratification, and potentially even depression.

Our days can become inundated by frivolous scrolling through endless social media feeds, responding to a constant stream of WhatsApp messages or wishing we were somewhere else, leading other more ‘interesting’ lives. “Don’t believe everything you read on social media,” a friend said to me the other day. It’s true. Many of us are a little guilty of some creative license when it comes to crafting a particular version of ourselves and how we’d like the world to see us. The Internet has also democratised freedom of speech, but that doesn’t mean every opinion is worthy of eyeballs. Who remembers the days before the Internet, when you had to pick up the telephone or write a letter to communicate? Now it seems amazing we survived those days (but we did).

In May 2018 I visited Lisbon, Portugal for the first time. Being a regular traveller, I thought there were some helpful tips that I could share with friends who would also be travelling to Lisbon in July for the first time for the Diamond Jubilee Celebration. So on the flight back home to Nairobi I wrote a few pointers and posted them on Facebook. The audience was limited; I had learned the value of privacy settings and the selective sharing of information many years ago, and that you didn’t always want ‘friends’ who may be a mix of close friends, family, acquaintances or business associates to necessarily know everything about you all the time. The morning after my return, my sister read me a few sentences from something she received on WhatsApp from a relative in Canada and asked if I had written it. I had.

Startlingly, it was the very same Facebook post that had somehow found its way from my Facebook feed into a message that was now being circulated on WhatsApp and email around the world. Over the coming weeks, that piece would be sent thousands of times amongst members of the global Jamat, all eager to find out more about planning their visits to Portugal. That’s the power of the digital age. While it can be useful, it can also be a means by which misinformation can spread easily and very fast. Knowing when to hit ‘forward’ or ‘delete’ is an acquired skill.

The Internet has shaken up so many parts of our lives but has also created a lot of collateral damage, especially when it comes to privacy. We often don’t realise the magnitude of our digital footprint, even for the most vigilant. Try Googling yourself — you’ll be surprised at some of the forgotten content you may have posted in the past that turns up in the search results. Some commentators have claimed that companies such as Google and Facebook own endless amounts of data on each of us. This could include your location, gender, age, hobbies, career, interests, relationship status, possible weight, income, where you’ve been, everything you’ve ever searched for (or deleted), every website you’ve ever visited, every Google ad you’ve clicked on, bookmarks, emails, contacts, your Google Drive files, your YouTube viewing history, the photos you’ve taken on your phone, the businesses you’ve bought from, the music you listen to, the pages you’ve shared, and even how many steps you walk in a day.

Even though I have always been an advocate for digital advancement, of late I have begun to feel skeptical about it. How do we take control of our digital lives in a way that does not encroach upon our own humanistic values? Most of us have been willing collaborators in letting technology into our lives and have given companies access to our data, allowing them to sell those insights and earn money from adverts in return for great tools and services.

But we need to strike a balance and be mindful of our own digital hygiene, or at least watch out for the pitfalls. How do we educate our elders to safely assimilate technology into their lives? How do we ensure our youth have the best possible chance at success without getting trapped in a vicious cycle of peer pressure, digital addiction, or unhealthy social influence? How do we safeguard that our children develop emotionally and psychologically, with the right balance of traditional and modern upbringing? These are all questions to which we need to search for answers. How we respond to the challenges of our digital future rests solely in our hands.

Adding new DNA letters make novel proteins possible

One such, a cancer drug, is now in development


The fuzzy specks growing on discs of jelly in Floyd Romesberg’s lab at Scripps Research in La Jolla look much like any other culture of E. coli. But appearances deceive—for the dna of these bacteria is written in an alphabet that has six chemical letters instead of the usual four.

Every other organism on Earth relies on a quartet of genetic bases: a (adenine), c (cytosine), t (thymine) and g (guanine). These fit together in pairs inside a double-stranded dna molecule, a matching t and c, g. But in 2014 Dr Romesberg announced that he had synthesised a new, unnatural, base pair, dubbed x and y, and slipped them into the genome of E. coli as well.

Kept supplied with sufficient quantities of x and y, the new cells faithfully replicated the enhanced dna—and, crucially, their descendants continued to do so, too. Since then, Dr Romesberg and his colleagues have been encouraging their new, “semisynthetic” cells to use the expanded alphabet to make proteins that could not previously have existed, and which might have properties that are both novel and useful. Now they think they have found one. In collaboration with a spin-off firm called Synthorx, they hope to create a less toxic and more effective version of a cancer drug called interleukin-2.
