Health Info from Apple Watches Will Allow Patients to “Take More Control”

(p. B1) SAN FRANCISCO — In the last months of Steve Jobs’s life, the Apple co-founder fought cancer while managing diabetes.
Because he hated pricking his finger to draw blood, Mr. Jobs authorized an Apple research team to develop a noninvasive glucose reader with technology that could potentially be incorporated into a wristwatch, according to people familiar with the events, who asked not to be identified because they were not authorized to speak on behalf of the company.
. . .
In September [2017], Apple announced that the Apple Watch would no longer need to be tethered to a smartphone and would become more of a stand-alone device. Since then, a wave of device manufacturers have tapped into the watch’s new features like cellular connectivity to develop medical accessories — such as an electrocardiogram for monitoring heart activity — so people can manage chronic conditions straight from their wrist.
. . .
(p. B4) A digital health revolution has been predicted for years, of course, and so far has been more hype than progress. But the hope is that artificial intelligence systems will sift through the vast amounts of data that medical accessories will collect from the Apple Watch and find patterns that can lead to changes in treatment and detection, enabling people to take more control of how they manage their conditions instead of relying solely on doctors.
Vic Gundotra, chief executive of AliveCor, a start-up that makes portable electrocardiograms, said this would put patients on a more equal footing with doctors because they would have more information on their own conditions.
“It’s changing the nature of the relationship between patient and doctor,” he said, adding that doctors will no longer be “high priests.”
. . .
Apple is also looking at potentially building an electrocardiogram into future models of the Apple Watch, according to a person familiar with the project, who spoke on the condition of anonymity because the details were confidential. It is unclear whether the EKG development, earlier reported by Bloomberg, would be introduced; such a product would most likely require F.D.A. clearance.
Separately, Apple is continuing research on a noninvasive continuous glucose reader, according to two people with knowledge of the project. The technology is still considered to be years away, industry experts said.
The current solution used by many diabetics is also coming to the Apple Watch. Dexcom, a maker of devices measuring blood sugar levels for diabetics, said it was awaiting F.D.A. approval for a continuous glucose monitor to work directly with the Apple Watch. Continuous glucose monitors use small sensors to pierce the skin to track blood sugar levels and relay those readings through a wireless transmitter.

“Eat Meat, Not Animals”

(p. 18) Run through anyone’s list of “disruptive” innovations in the works today and they begin to seem like small-time stuff as we contemplate “Clean Meat: How Growing Meat Without Animals Will Revolutionize Dinner and the World.” Driverless cars, virtual reality, robots–these are interesting possibilities. But slaughter-free flesh for humanity, meat without misery, dinner without death: Now we’re talking “transformational.”
Who would not wish–all the more so if it meant giving up nothing–to make the abattoirs of the world fall silent? Suppose, as Paul Shapiro asks us to imagine, that after 10,000 or so years of raising other creatures for the killing, and some 60 years of raising them in the pitiless conditions of factory farms, we produced meat and other animal products from cultured cells, with no further need of the animals themselves, or at least no need that required their suffering.
. . .
To assume that the entrepreneurs and scientists described in “Clean Meat” cannot one day match precisely the beef, pork, chicken, duck and all the rest that carnivores demand is a bet against human ingenuity. Consider how close plant-based alternatives to meat, milk and eggs have come already. Not for nothing has Tyson Foods acquired a 5% stake in the startup Beyond Meat, through a venture fund focused, as Tyson announced, on “breakthrough technologies,” including clean meat.
“Eat Meat, Not Animals”–a slogan of the future, Mr. Shapiro hopes.

FLEGENHEIMER Washington’s most prolific consumer of pop culture is very likely … Ted Cruz. Amateur “S.N.L.” historian, ’80s movie buff and instigator of a Twitter feud with Mark Hamill over net neutrality. He explained the meaning of “Star Wars” to Luke Skywalker. It was very Cruz: @HammillHimself Luke, I know Hollywood can be confusing, but it was Vader who supported govt power over everything said & done on the Internet.

Why People Have Trouble Taking Global Warming Seriously

(p. A15) It was only getting worse here and all across the Northeast in the wake of a “bomb cyclone” that turned Boston streets into an Arctic sea and left three-foot snowdrifts across New England. Weather forecasters were predicting temperature lows that could shatter century-old records in Worcester, Mass., Hartford and elsewhere.
Millions of people from Florida to Maine were left shivering as schools closed and flights were canceled this week. Officials said that seven deaths appeared to be tied to the weather.
Windows splintered. Car batteries died. Along the Maine coastline, the flooding left icebergs in people’s yards. Ice fishermen had to keep their smelt bait close to them for fear it would freeze solid. Even snowmobiles coughed and sputtered and refused to start.
Across this American tundra, people called their heating-oil companies for emergency supplies and sat stranded on the sides of roads as tow-truck companies reported five-hour wait times to jump-start a dead battery or tow away a snowbound car. People slept in winter coats and debated whether wool, cotton or silk made for the best long underwear.

Badly Understood Starfish Causes Half of Great Barrier Reef Decline

(p. A9) BYRON BAY, Australia — The Great Barrier Reef is literally being eaten alive.
. . .
One study found that between 1985 and 2012, the reef lost an average of 50 percent of its coral cover. Starfish predation was responsible for almost half that decline, along with tropical cyclones and bleaching.
The cause of the outbreak is unknown. One hypothesis is that currents are bringing nutrient-rich water from the deep sea up into the shelf, which correlates with starfish larvae growth.
. . .
Coral reefs are constantly undergoing change, and they follow a cycle of death and renewal, said Hugh Sweatman, a scientist from the Australian Institute of Marine Sciences.

Revival of the Resilient Brer Rabbit

(p. C23) When Robert Weil, the editor in chief and publishing director of Liveright, approached Henry Louis Gates Jr. and Maria Tatar with the idea of putting together “The Annotated African American Folktales,” the two Harvard professors responded with a mix of excitement and trepidation.
. . .
“The Annotated African American Folktales,” which came out in November [2017], contains more than 100 African and African-American folk tales as well as introductory essays and commentary to provide historical context. It draws from the rich, undersung work of folklorists from West Africa to the Deep South.
. . .
Professors Gates and Tatar . . . tackle controversial parts of folklore history, dedicating a chapter to the work of Joel Chandler Harris.
. . .
The decision to include Harris’s work in this collection produced lively discussions between Mr. Gates and Ms. Tatar. “I felt uncomfortable with it,” Ms. Tatar said. But Mr. Gates disagreed. The exchange proved to be a key moment of collaboration.
“In my house, growing up in Piedmont, West Virginia, we collected Mother Goose and Joel Chandler Harris,” he said. “My father used to tell Brer Rabbit stories to my brother and me all the time.”
. . .
In the late 19th century and early 20th century, African-Americans debated whether these folk tales were worth preserving. Some people considered the stories remnants of slavery rather than evidence of ingenuity.
The novelist Toni Morrison, however, has played an important role in validating these stories by integrating them into her writing, Ms. Tatar said.
While Ms. Morrison’s novels contain traces of innovative uses of folklore, “Tar Baby” is the most obvious and the one Mr. Gates was particularly eager to include in this collection. Not only is it one of his favorite stories but he also finds the appearance of the tar baby in many cultures “haunting.” The original folk tale is the story of Brer Fox and Brer Rabbit. Angry that Brer Rabbit is always stealing from his garden, Brer Fox makes a tar baby. Brer Rabbit comes across the figure and tries to start a conversation. He grows frustrated by the lack of response and hits the tar baby, only to find his paw stuck in what is a doll made of tar and turpentine.
. . .
Folk tales give us “ancestral wisdom,” they teach children lessons about compassion, forgiveness and respect, said Ms. Tatar. They take us “back to the people who lived before us.” They help us “navigate the future.”
Mr. Gates couldn’t agree more. He has dedicated this labor of love to his 3-year-old granddaughter. He wants the book to be not just for her and black children of her generation, but for all American children.

Tax Overhaul “Armageddon”

(p. A19) To travel the liberal byways of social media over recent weeks was to learn that Donald Trump was on the precipice of axing Robert Mueller and was likely to use the days just before Christmas, when we were distracted by eggnog and mistletoe, to lower the blade.
Christmas has come. Christmas has gone. Mueller has not.
To listen to Nancy Pelosi and other Democratic leaders, the tax overhaul that Trump just signed into law is no mere plutocratic folly. It’s “Armageddon” (Pelosi’s actual word). Their opposition is righteous, but how will millions of voters who notice smaller withholdings from their paychecks and more money in their pockets square that seemingly good fortune with such prophecies of doom on a biblical scale?
Some of these Americans may decide that the prophets aren’t to be trusted — and that the president isn’t quite the pestilence they make him out to be.

Some Elevator Operator Jobs Remain

(p. 10) There are 69,381 passenger elevators in this vertically obsessed city, and nearly all of them promise a journey about as exotic and exciting as making toast. You get in, you push a button, the doors open a few seconds later at your destination.
But there remain quite a few machines, manually controlled and chauffeur-driven, where climbing aboard is more like taking a short trip on the Orient Express.
. . .
Most of the elevators are in residential buildings, but a few war horses serve heavy duty in commercial complexes.
Collectively they form a hidden museum of obsolete technology and anachronistic employment, a network of cabinets of wonder staffed round the clock. No one knows how many there are, exactly. The city Department of Buildings offered a list of more than 600, but spot checks indicated that most had gone push-button long ago. On the other hand, officials at Local 32BJ of the Service Employees International Union, to which most doormen and elevator operators belong, said they knew of only one or two.
A non-exhaustive field survey this fall turned up 53 buildings with manual passenger elevators. There are undoubtedly dozens more, but probably not hundreds.
Why they still exist in such relative profusion, when the city is down to its last few seltzer men and its final full-time typewriter repair shop, when replacement parts are no longer made and must be machined by hand, is a question with many answers. But sentiment plays a large part.
. . .
Push-button elevators had actually been around since the 1890s, but were not practical for larger buildings. They were slow. Initially they could make only one stop per trip. Later, they could make multiple stops, but only in the order the buttons were pressed.
It took until 1950 for Otis to perfect a push-button system smart enough to handle the traffic and shifting demands for service over the course of the day in a multi-elevator building. The company’s Autotronic system, Otis boasted in advertisements, “minimizes the human element” and “gives tenants a sprightly feeling of independence.”
The elevator man’s fate was sealed.
Almost.

DeepMind Mastered “Go” Only After It Was Told the Score

(p. C3) To function well outside controlled settings, robots must be able to approximate such human capacities as social intelligence and hand-eye coordination. But how to distill them into code?
“It turns out those things are really hard,” said Cynthia Breazeal, a roboticist at the Massachusetts Institute of Technology’s Media Lab.
. . .
Even today’s state-of-the-art AI has serious practical limits. In a recent paper, for example, researchers at MIT described how their AI software misidentified a 3-D printed turtle as a rifle after the team subtly altered the coloring and lighting for the reptile. The experiment showed the ease of fooling AI and raised safety concerns over its use in real-world applications such as self-driving cars and facial-recognition software.
Current systems also aren’t great at applying what they have learned to new situations. A recent paper by the AI startup Vicarious showed that a proficient Atari-playing AI lost its prowess when researchers moved around familiar features of the game.
. . .
Google’s DeepMind subsidiary used a technique known as reinforcement learning to build software that has repeatedly beat the best human players in Go. While learning the classic Chinese game, the machine got positive feedback for making moves that increased the area it walled off from its competitor. Its quest for a higher score spurred the AI to develop territory-taking tactics until it mastered the game.
The problem is that “the real world doesn’t have a score,” said Brown University roboticist Stefanie Tellex. Engineers need to code into AI programs so-called “reward functions”–mathematical ways of telling a machine it has acted correctly. Beyond the finite scenario of a game, amid the complexity of real-life interactions, it’s difficult to determine what results to reinforce. How, and how often, should engineers reward machines to guide them to perform a certain task? “The reward signal is so important to making these algorithms work,” Dr. Tellex added.
. . .
If a robot needs thousands of examples to learn, “it’s not clear that’s particularly useful,” said Ingmar Posner, the deputy director of the Oxford Robotics Institute in the U.K. “You want that machine to pick up pretty quickly what it’s meant to do.”

Will Ending Firm Hierarchy Create “a Blissful Business Utopia”?

(p. 18) “The Kingdom of Happiness” doesn’t take place in Silicon Valley per se, but it is definitively about tech culture. Groth follows Tony Hsieh, the creator of Zappos, as he pours $350 million of his personal wealth into downtown Las Vegas with the goal of reinventing the area as . I won’t be giving away the story by pointing out that it doesn’t end well for Hsieh, . . .”
. . .
When she’s sober, Groth documents Hsieh’s attempt to integrate “holacracy” into his organizations, a term that rids a company of hierarchy and titles, and instead creates an all-for-one do-what-you-want mentality. (No, I’m not kidding.) It gave me a panic attack just thinking of working in a place like that.

Rise in Cobalt Price Will Increase Quantity Supplied, and Increase Search for Substitutes

(p. B14) . . . the dreaded shortage of cobalt, which is used in the cathode of the batteries, is a bit more complicated than industry projections would suggest.
. . .
Like cobalt, rare earths aren’t so rare. China’s move to restrict exports in 2010 exacerbated the perceived shortage, sending the prices of some varieties up 10-fold. Companies such as Molycorp, Rare Element Resources Ltd. and Quest Rare Mineral Ltd., which all had some connection to reserves, saw their shares surge based on supposedly rosy prospects. Since then, all have lost nearly all of their value.
Already, Mr. Heppel explains, other users of the metal, for example in the pigments industry, are searching for alternatives. Meanwhile, some batteries, such as a design by Tesla, use less of the metal. Lower-performing batteries use none at all, and those batteries’ capabilities may improve with technological tweaks.
Supply will react too. Companies that operate copper and nickel mines, where cobalt is co-produced, are targeting expansion, and there are some pure-play cobalt mines being planned that could start producing shortly after the projected shortage hits.
For electric vehicles, this looks more like a speed bump than a cliff.
