Space Trash Start-Up Aims to Be Quicker than Government

(p. D1) Mr. Okada is an entrepreneur with a vision of creating the first trash collection company dedicated to cleaning up some of humanity’s hardest-to-reach rubbish: the spent rocket stages, inert satellites and other debris that have been collecting above Earth since Sputnik ushered in the space age. He launched Astroscale three years ago in the belief that national space agencies were dragging their feet in facing the problem, which could be tackled more quickly by a small private company motivated by profit.
“Let’s face it, waste management isn’t sexy enough for a space agency to convince taxpayers to allocate money,” said Mr. Okada, 43, who put Astroscale’s headquarters in start-up-friendly Singapore but is building its spacecraft in his native Japan, where he found more engineers. “My breakthrough is figuring out how to make this into a business.”
. . .
(p. D3) “The projects all smelled like government, not crisp or quick,” he said of conferences he attended to learn about other efforts. “I came from the start-up world where we think in days or weeks, not years.”
. . .
He also said that Astroscale would start by contracting with companies that will operate big satellite networks to remove their own malfunctioning satellites. He said that if a company has a thousand satellites, several are bound to fail. Astroscale will remove these, allowing the company to fill the gap in its network by replacing the failed unit with a functioning satellite.
“Our first targets won’t be random debris, but our clients’ own satellites,” he said. “We can build up to removing debris as we perfect our technology.”

Gates Foundation Funding “Second Green Revolution”

(p. A12) URBANA, Ill. — A decade ago, agricultural scientists at the University of Illinois suggested a bold approach to improve the food supply: tinker with photosynthesis, the chemical reaction powering nearly all life on Earth.
The idea was greeted skeptically in scientific circles and ignored by funding agencies. But one outfit with deep pockets, the Bill and Melinda Gates Foundation, eventually paid attention, hoping the research might help alleviate global poverty.
Now, after several years of work funded by the foundation, the scientists are reporting a remarkable result.
Using genetic engineering techniques to alter photosynthesis, they increased the productivity of a test plant — tobacco — by as much as 20 percent, they said Thursday[November 17, 2016] in a study published by the journal Science. That is a huge number, given that plant breeders struggle to eke out gains of 1 or 2 percent with more conventional approaches.
The scientists have no interest in increasing the production of tobacco; their plan is to try the same alterations in food crops, and one of the leaders of the work believes production gains of 50 percent or more may ultimately be achievable. If that prediction is borne out in further research — it could take a decade, if not longer, to know for sure — the result might be nothing less than a transformation of global agriculture.
. . .
“We’re here because we want to alleviate poverty,” said Katherine Kahn, the officer at the Gates Foundation overseeing the grant for the Illinois research. “What is it (p. A24) the farmers need, and how can we help them get there?”
One of the leaders of the research, Stephen P. Long, a crop scientist who holds appointments at the University of Illinois at Urbana-Champaign and at Lancaster University in England, emphasized in an interview that a long road lay ahead before any results from the work might reach farmers’ fields.
But Dr. Long is also convinced that genetic engineering could ultimately lead to what he called a “second Green Revolution” that would produce huge gains in food production, like the original Green Revolution of the 1960s and 1970s, which transferred advanced agricultural techniques to some developing countries and led to reductions in world hunger.
. . .
The work is, in part, an effort to secure the food supply against the possible effects of future climate change. If rising global temperatures cut the production of food, human society could be destabilized, but more efficient crop plants could potentially make the food system more resilient, Dr. Long said.

Making Technologies Useful to End Users Can Be Hard

Sharma’s theory sounds somewhat similar to that of Bhidé in his The Venturesome Economy.

(p. B4) Anshu​ Sharma,​ a venture capitalist at Storm Ventures, thinks he knows why so many companies that should have all the resources and brainpower required to build the next big thing so often fail to. He calls his thesis the “stack fallacy,” and though he sketched its outline in a recent essay, I found it so compelling that I thought it worth a more thorough exploration of the implications of his theory. What follows is the result of that conversation.

“Stack fallacy is the mistaken belief that it is trivial to build the layer above yours,” Mr. Sharma wrote. And as someone who worked at both Oracle and Salesforce, his exhibit A is these two companies. To Oracle, which is primarily a database company, Salesforce is just a “hosted database app,” he wrote. and yet despite spending millions on it, Oracle has been unable to beat Salesforce in Salesforce’s core competency, notably customer-relations management software.
It helps to understand that in tech, the “stack” is the layer cake of technology, one level of abstraction sitting atop the next, that ultimately delivers a product or service to the user. On the Internet, for example, there is a stack of technologies stretching from the server through the operating system running on it through a cloud abstraction layer and then the apps running atop that, until you reach the user. Even the electricity grid required to power the data center in which the server lives could be considered part of the technology “stack” of, say, your favorite email service.
. . .
The reason that companies fail when they try to move up the stack is simple, argues Mr. Sharma: They don’t have firsthand empathy for what customers of the product one level above theirs in the stack actually want. Database engineers at Oracle don’t know what supply-chain managers at Fortune 500 companies want out of an enterprise resource-planning system like SAP, but that hasn’t stopped Oracle from trying to compete in that space.

Modern Technology Adds to Knowledge of Culture and Religion

(p. A6) Nearly half a century ago, archaeologists found a charred ancient scroll in the ark of a synagogue on the western shore of the Dead Sea.
The lump of carbonized parchment could not be opened or read. Its curators did nothing but conserve it, hoping that new technology might one day emerge to make the scroll legible.
Just such a technology has now been perfected by computer scientists at the University of Kentucky. Working with biblical scholars in Jerusalem, they have used a computer to unfurl a digital image of the scroll.
It turns out to hold a fragment identical to the Masoretic text of the Hebrew Bible and, at nearly 2,000 years old, is the earliest instance of the text.
The writing retrieved by the computer from the digital image of the unopened scroll is amazingly clear and legible, in contrast to the scroll’s blackened and beaten-up exterior. “Never in our wildest dreams did we think anything would come of it,” said Pnina Shor, the head of the Dead Sea Scrolls Project at the Israel Antiquities Authority.
Scholars say this remarkable new technique may make it possible to read other scrolls too brittle to be unrolled.
. . .
The experts say this new method may make it possible to read other ancient scrolls, including several Dead Sea scrolls and about 300 carbonized ones from Herculaneum, which were destroyed by the volcanic eruption of Mount Vesuvius in A.D. 79.
. . .
The feat of recovering the text was made possible by software programs developed by W. Brent Seales, a computer scientist at the University of Kentucky. Inspired by the hope of reading the many charred and unopenable scrolls found at Herculaneum, near Pompeii in Italy, Dr. Seales has been working for the last 13 years on ways to read the text inside an ancient scroll.
. . .
He succeeded in 2009 in working out the physical structure of the ruffled layers of papyrus in a Herculaneum scroll.
He has since developed a method, called virtual unwrapping, to model the surface of an ancient scroll in the form of a mesh of tiny triangles. Each triangle can be resized by the computer until the virtual surface makes the best fit to the internal structure of the scroll, as revealed by the scanning method. The blobs of ink are assigned to their right place on the structure, and the computer then unfolds the whole 3-D structure into a 2-D sheet.

Denmark Drones Saving Lives

(p. B1) Mr. McLinden is a member of a group of middle-aged emergency workers taking part in a trial to jump-start the use of unmanned aircraft by Europe’s emergency services. The goal is to give the region a head start over the United States and elsewhere in using drones to tackle real-world emergencies.
The “drone school” builds on Europe’s worldwide lead in giving public groups and companies relatively free rein to experiment with unmanned aircraft. If everything goes as planned, the project’s backers hope government agencies in Europe and farther afield can piggyback on the experiences, helping to transform drones from recreational toys to lifesaving tools.
“For us, this technology is a game-changer,” said Mr. McLinden, who traveled to Copenhagen (p. B4) for a three-day training course with two colleagues from the Mid and West Wales Fire and Rescue Service. They will start offering 24/7 drone support — allowing colleagues, for example, to monitor accidents from 300 feet above — across central Wales later this month.
“Drones aren’t going to replace what we do,” Mr. McLinden added. “But anything that we can do to give our crews an advantage, that’s great.”
. . .
In a somewhat stuffy classroom at a disused fire station in Copenhagen, Thomas Sylvest gave advice to Mr. McLinden and others from his two years of flying. As Denmark’s first, and so far only, emergency service drone pilot, Mr. Sylvest has responded to things as varied as missing person cases and fires, often receiving calls late at night.
Mr. Sylvest, a fast-talking 50-year-old, offered tips on how best to share videos streamed directly from drones to commanders on the ground. During a recent fire in downtown Copenhagen, Mr. Sylvest said, he was able to beam high-definition images from high above, allowing his bosses to judge if a building’s walls would collapse (they did not). And when the police called him out last year after a man was reported missing, he flew his drone along a stretch of train tracks to guide colleagues on where best to look. (The man was found.)

Crony Credentialism Is Regulatory Barrier to Telemedicine

(p. A11) Telemedicine has made exciting advances in recent years. Remote access to experts lets patients in stroke, neonatal and intensive-care units get better treatment at a lower cost than ever before. In rural communities, the technology improves timely access to care and reduces expensive medevac trips. Remote-monitoring technology lets patients with chronic conditions live at home rather than in an assisted-living facility.
Yet while telemedicine can connect a patient in rural Idaho with top specialists in New York, it often runs into a brick wall at state lines. Instead of welcoming the benefits of telemedicine, state governments and entrenched interests use licensing laws to make it difficult for out-of-state experts to offer remote care.
. . .
Using its power under the Commerce Clause of the Constitution, Congress could pass legislation to define where a physician practices medicine to be the location of the physician, rather than the location of the patient, as states currently do. Physicians would need only one license, that of their home state, and would work under its particular rules and regulations.
This would allow licensed physicians to treat patients in all 50 states. It would greatly expand access to quality medical care by freeing millions of patients to seek services from specialists around the country without the immense travel costs involved.

Creative Destruction of Polaroid by Digital Photography

(p. A17) There aren’t many 3-year-olds who can take credit for inspiring a revolution in the way millions of people view the world. According to a legend that begins Peter Buse’s welcome history of the Polaroid company, “The Camera Does the Rest,” it was engineer Edwin Land’s daughter, Jennifer, who asked one evening in 1943 why it took so long to view the photographs that the family had shot while on vacation in Santa Fe, N.M. Land set out on a walk to ponder that question and, so the story goes, returned six hours later with an answer that would transform the hidebound practice of photography: the instant snapshot.
. . .
“In 1974 alone there were about 1 billion Polaroid images made, and by 1976 . . . 15 billion in total,” the author writes, “and this before the real explosion in Polaroid photography in the late 1970s and early 1980s.” The party might have gone on forever had it not been for the same type of creative destruction that Polaroid itself had stirred up in the 1940s–this time brought about by the digital revolution.
By the time the company joined that revolution in the 1990s, it was too late. Their digital products were inferior to those being turned out by competing companies. Polaroid had always done well selling cameras, but the real money was in the film, the demand for which was falling precipitately. In July 1997, the company’s stock price was $60.51. Four years later, as the company spiraled toward bankruptcy, it was $0.49. The author writes that Polaroid joined the “analog scrap heap” that included “vinyl turntables and the Sony Walkman.”​

Tesla and Google Bet on Different Paths to Driverless Cars

(p. B1) SAN FRANCISCO — In Silicon Valley, where companies big and small are at work on self-driving cars, there have been a variety of approaches, and even some false starts.
The most divergent paths may be the ones taken by Tesla, which is already selling cars that have some rudimentary self-driving functions, and Google, which is still very much in experimental mode.
Google’s initial efforts in 2010 focused on cars that would drive themselves, but with a person behind the wheel to take over at the first sign of trouble and a second technician monitoring the navigational computer.
As a general concept, Google was trying to achieve the same goal as Tesla is claiming with the Autopilot feature it has promoted with the Model S, which has hands-free technology that has come under scrutiny after a fatal accident on a Florida highway.
But Google decided to play down the vigilant-human approach after an experiment in 2013, when the company let some of its employees sit behind the wheel of the self-driving cars on their daily commutes.
Engineers using onboard video cameras to remotely monitor the results were alarmed by what (p. B5) they observed — a range of distracted-driving behavior that included falling asleep.
“We saw stuff that made us a little nervous,” Christopher Urmson, a former Carnegie Mellon University roboticist who directs the car project at Google, said at the time.
The experiment convinced the engineers that it might not be possible to have a human driver quickly snap back to “situational awareness,” the reflexive response required for a person to handle a split-second crisis.
So Google engineers chose another route, taking the human driver completely out of the loop. They created a fleet of cars without brake pedals, accelerators or steering wheels, and designed to travel no faster than 25 miles an hour.
For good measure they added a heavy layer of foam to the front of their cars and a plastic windshield, should the car make a mistake. While not suitable for high-speed interstate road trips, such cars might one day be able to function as, say, robotic taxis in stop-and-go urban settings.

Technology Can Restore Hand Control to Quadriplegic

(p. A1) Five years ago, a college freshman named Ian Burkhart dived into a wave at a beach off the Outer Banks in North Carolina and, in a freakish accident, broke his neck on the sandy floor, permanently losing the feeling in his hands and legs.
On Wednesday [April 13, 2016], doctors reported that Mr. Burkhart, 24, had regained control over his right hand and fingers, using technology that transmits his thoughts directly to his hand muscles and bypasses his spinal injury. The doctors’ study, published by the journal Nature, is the first account of limb reanimation, as it is known, in a person with quadriplegia.
Doctors implanted a chip in Mr. Burkhart’s brain two years ago. Seated in a lab with the implant connected through a computer to a sleeve on his arm, he was able to learn by repetition and arduous practice to focus his thoughts to make his hand pour from a bottle, and to pick up a straw and stir. He was even able to play a guitar video game.
. . .
“Watching him close his hand for the first time — I mean, it was a surreal moment,” Dr. Rezai said. “We all just looked at each other and thought, ‘O.K., the work is just starting.'”
After a year of training, Mr. Burkhart was able to pick up a bottle and pour the contents into a jar, and to pick up a straw and stir. The doctors, though delighted, said that more advances would be necessary to make the bypass system practical, affordable and less invasive, most likely through wireless technology. But the improvement was significant enough, at least in the lab, that rehabilitation specialists could reclassify Mr. Burkhart’s disability from a severe C5 function to a less severe C7 designation.
For now, the funding for the project, which includes money from Ohio State, Battelle and private donors, is set to run out this year — and with it, Mr. Burkhart’s experience of restored movement.
“That’s going to be difficult, because I’ve enjoyed it so much,” Mr. Burkhart said. “If I could take the thing home, it would give me so much more independence. Now, I’ve got to rely on someone else for so many things, like getting dressed, brushing my teeth — all that. I just want other people to hear about this and know that there’s hope. Something will come around that makes living with this injury better.”

Scientific Knowledge Matters More than Myth Because of Its Practical Effectiveness

(p. C6) Stories matter; knowledge matters more.
“When we talk about the big bang or the fabric of space,” . . . [Carlo Rovelli] writes, “what we are doing is not a continuation of the free and fantastic stories that humans have told nightly around campfires for hundreds of thousands of years.” You might tell a great campfire story about an antelope, he comments. Knowing how to track and kill one is more relevant to survival.
“Myths nourish science, and science nourishes myth,” Mr. Rovelli says. “But the value of knowledge remains. If we can find the antelope, we can eat.”
