Patients Lower Blood Pressure Best When It Is Self-Monitored

(p. D4) The most effective way to monitor blood pressure may be to do it yourself.
British researchers randomly assigned 1,003 patients with hypertension to one of three groups.
. . .
The study was published in Lancet.
“People who monitor their own blood pressure and share the readings with their physician get better control,” said the lead author, Dr. Richard J. McManus, a professor of primary care at the University of Oxford. “Seventy-five million Americans have hypertension. If a good proportion of those self-monitored, it would lead to a big reduction in stroke.”

“Octopuses Try Hard to Escape from Captivity”

(p. A23) I can’t stop telling people about the factoids I learned from Amia Srinivasan’s book review essay “The Sucker, the Sucker!” in The London Review of Books about the personality of octopuses. An octopus’s arms have more neurons than its brain, so each arm can taste and smell on its own and exhibit short-term memory. An octopus can change color to mimic other animals, but it cannot itself see color. So how does it know which color to change into? Good question.
Octopuses are curious but sometimes ornery. When researchers tried to train an octopus to pull a lever to get food, the octopus kept breaking off the lever. Octopuses try hard to escape from captivity, waiting for those moments when they aren’t being watched. One octopus persistently shot jets of water at the nearby aquarium light bulbs, repeatedly short-circuiting the electricity supply until it was finally released into the wild.

“Overblown” Worries that A.I. Will Make Humans Obsolete

(p. B3) SAN FRANCISCO — Apple has hired Google’s chief of search and artificial intelligence, John Giannandrea, a major coup in its bid to catch up to the artificial intelligence technology of its rivals.
. . .
Mr. Giannandrea, a 53-year-old native of Scotland known to colleagues as J.G., helped lead the push to integrate A.I. throughout Google’s products, including internet search, Gmail and its own digital assistant, Google Assistant.
He joined Google in 2010 when it purchased Metaweb, a start-up where he served as chief technology officer. Metaweb was building what it described as a “database of the world’s knowledge,” which Google eventually rolled into its search engine to deliver direct answers to users’ queries. (Try googling “How old is Steph Curry?”) During Mr. Giannandrea’s tenure, A.I. research became increasingly important inside Google, with its primary A.I. lab, Google Brain, moving into a space beside the chief executive, Sundar Pichai.
. . .
On the debate over whether humanity should be worried about the rapidly accelerating improvements in A.I., Mr. Giannandrea told MIT Technology Review in an interview last year that the concerns were overblown.
“What I object to is this assumption that we will leap to some kind of superintelligent system that will then make humans obsolete,” he said. “I understand why people are concerned about it but I think it’s gotten way too much airtime. I just see no technological basis as to why this is imminent at all.”

Millions of Dollars and 30 Years Later, A.I. Still Has Lacks Crucial Common Sense

(p. B6) SAN FRANCISCO — Microsoft’s co-founder Paul Allen said Wednesday [February 28, 2018] that he was pumping an additional $125 million into his nonprofit computer research lab for an ambitious new effort to teach machines “common sense.”
. . .
“To make real progress in A.I., we have to overcome the big challenges in the area of common sense,” said Mr. Allen, who founded the software giant Microsoft in the 1970s with Bill Gates.
. . .
In the mid-1980s, Doug Lenat, a former Stanford University professor, with backing from the government and several of the country’s largest tech companies, started a project called Cyc. He and his team of researchers worked to codify all the simple truths that we learn as children, from “you can’t be in two places at the same time” to “when drinking from a cup, hold the open end up.”
Thirty years later, Mr. Lenat and his team are still at work on this “common sense engine” — with no end in sight.
Mr. Allen helped fund Cyc, and he believes it is time to take a fresh approach, he said, because modern technologies make it easier to build this kind of system.
Mr. Lenat welcomed the new project. But he also warned of challenges: Cyc has burned through hundreds of millions of dollars in funding, running into countless problems that were not evident when the project began. He called them “buzz saws.”

Virtual Reality Was Intended as a Complement to Physical Reality, Not as a Substitute

(p. A17) The illusion of presence is what drove Mr. Lanier from the start. He envisioned VR not as an alternative to physical reality but as an enhancement–a way to more fully appreciate the wonder of existence. More conventional individuals, their senses dulled by the day-to-day, may be drawn to virtual reality because it seems realer than real; he considered it a new form of communication. “I longed to see what was inside the heads of other people,” he writes. “I wanted to show them what I explored in dreams. I imagined virtual worlds that would never grow stale because people would bring surprises to each other. I felt trapped without this tool. Why, why wasn’t it around already?”
“Dawn of the New Everything” is full of such self-revelatory moments. The author grew up an only child in odd corners of the Southwest, first on the Texas-Mexico border, then in the desert near White Sands Missile Range. When he was nine, his mother, a Holocaust survivor, was killed in a car crash on the way home from getting her driver’s license. The tract house they’d bought burned down the day after construction was completed. The insurance money never came, so Jaron and his father lived in tents in the desert until they could afford to build a real home–which turned out to be a mad concoction of geodesic domes of Jaron’s own design. They called it Earth Station Lanier.
. . .
Lacking a degree from high school, never mind college, he nonetheless parlayed his virtual-reality obsession into a company, VPL Research, that for a few years in the late ’80s made VR seem real, if only in a lab setting. Then came board fights and bankruptcy, and VR disappeared from public view for more than 20 years.
What went wrong at VPL? Unfortunately, you won’t find out here. Mr. Lanier warns us he isn’t going to deliver a blow-by-blow; instead we get a disjointed sequence of half-remembered anecdotes. What does come through is his ambivalence about going into business at all, and his even deeper ambivalence toward writing about it.

Obstacles and Conflicts Were Too Much for Lanier’s “VPL Research” Startup

(p. 11) Lanier’s book is, . . . , intimate and idiosyncratic. He carries us through his quirky and fascinating life story, with periodic nerdy side trips through his early thinking on more technical aspects of virtual reality. If you liked Richard Feynman’s autobiographical “Surely You’re Joking, Mr. Feynman” but thought it was rather self-indulgent, this book will prompt similar reactions. You could almost say that Lanier’s vivid and creative imagination is a distinct character in this book, he discusses it so much. Midway through, Feynman himself makes an appearance, and it seems as if we’re meeting an old friend.
Lanier has been credited with inventing the term “virtual reality,” and he founded one of the original companies to produce it, VPL Research. He goes over the technology’s history in detail, outlining not only the obstacles to getting consistent hardware but some personalities and interpersonal conflicts that ultimately led to his company’s breaking up. He also demonstrates the role personal connections and interactions play in Silicon Valley.

Level of Loneliness About the Same as 70 Years Ago

(p. 8) . . . is loneliness, as many political officials and pundits are warning, a growing “health epidemic”?
. . .
The main evidence for rising isolation comes from a widely reported sociology journal article claiming that in 2004, one in four Americans had no one in their life they felt they could confide in, compared with one in 10 during the 1980s. But that study turned out to be based on faulty data, and other research shows that the portion of Americans without a confidant is about the same as it has long been. Although one of the authors has distanced himself from the paper (saying, “I no longer think it’s reliable”), scholars, journalists and policymakers continue to cite it.
The other data on loneliness are complicated and often contradictory, in part because there are so many different ways of measuring the phenomenon. But it’s clear that the loneliness statistics cited by those who say we have an epidemic are outliers. For example, one set of statistics comes from a study that counted as lonely people who said they felt “left out” or “isolated,” or “lacked companionship” — even just “some of the time.” That’s an exceedingly low bar, and surely not one we’d want doctors or policymakers to use in their work.
One reason we need to be careful about how we measure and respond to loneliness is that, as the University of Chicago psychologist John Cacioppo argues, an occasional and transitory feeling of loneliness can be healthy and productive. It’s a biological signal to ourselves that we need to build stronger social bonds.
Professor Cacioppo has spent much of his career documenting the dangers of loneliness. But it’s notable that he relies on more measured statistics in his own scientific papers than the statistics described above. One of his articles, from last year, reports that around 19 percent of older Americans said they had felt lonely for much of the week before they were surveyed, and that in Britain about 6 percent of adults said they felt lonely all or most of the time. Those are worrisome numbers, but they are quite similar to the numbers reported in Britain in 1948, when about 8 percent of older adults said they often or always felt lonely, and to those in previous American studies as well.

Child Prodigies Seldom Excel as Adults

(p. 15) Child prodigies are exotic creatures, each unique and inexplicable. But they have a couple of things in common, as Ann Hulbert’s meticulous new book, “Off the Charts,” makes clear: First, most wunderkinds eventually experience some kind of schism with a devoted and sometimes domineering parent. “After all, no matter how richly collaborative a bond children forge with grown-up guides, some version of divorce is inevitable,” Hulbert writes. “It’s what modern experts would call developmentally appropriate.” Second, most prodigies grow up to be thoroughly unremarkable on paper. They do not, by and large, sustain their genius into adulthood.
. . .
The very traits that make prodigies so successful in one arena — their obsessiveness, a stubborn refusal to conform, a blistering drive to win — can make them pariahs in the rest of life. Whatever else they may say, most teachers do not in fact appreciate creativity and critical thinking in their own students. “Off the Charts” is jammed with stories of small geniuses being kicked out of places of learning. Matt Savage spent two days in a Boston-area Montessori preschool before being expelled. Thanks to parents who had the financial and emotional resources to help him find his way, he is now, at age 25, a renowned jazz musician.

Cognitive Abilities Highest After Waking in Morning

(p. A15) A raft of studies in disciplines ranging from medicine to economics have yielded all sorts of data on the science of timing. Daniel Pink, an author who regularly applies behavioral science to the realm of work, has handily distilled the findings in “When: The Scientific Secrets of Perfect Timing.”
. . .
For a slim book, “When” brims with a surprising amount of insight and practical advice. In amiable, TED-talk-ready prose, Mr. Pink offers scheduling tips for everything from workouts to weddings. Exercise, for example, is best done in the morning for those who hope to lose weight, build strength and boost their mood through the day.
. . .
Moods are not the only things that shift every 24 hours. Our cognitive abilities also morph in foreseeable ways. We are often sharpest in the hours after waking up, which makes morning the best time to take exams or answer logic problems. Researchers analyzing four years of test results for two million Danish schoolchildren found that students consistently scored higher in mornings than afternoons.

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.”

For Jane Jacobs, “Self-Certainty” Was Better than a Doctorate

(p. 17) Like the critic Pauline Kael and the conservative activist Phyllis Schlafly, Jane Jacobs arrived to churn the fertile soil of American cultural ideology in the 1960s, brandishing a disciplined populist intellect and a comfort with courting enmity. All three were middle-aged mothers by the time they would shake things up. That Jacobs, nee Butzner in 1916, would force a reconsideration of the nature and purpose of cities was an outcome her young adulthood would have hardly suggested. An unexceptional student at Central High in Scranton, Pa., she later studied at Columbia before failing to gain formal admission to Barnard and abandoning the pursuit of a degree entirely. These experiences, Robert Kanigel maintains in his biography “Eyes on the Street: The Life of Jane Jacobs,” left her with a distaste for the academy that she carried throughout her career.
Where others had doctorates, Jacobs had a self-certainty that was manifest early on. In a chronicling of her childhood so thorough it includes the number of times she was late for homeroom during her first semester of high school (seven), Kanigel recounts an incident in which Jane was expelled from third grade for urging her classmates to dismiss the entreaties of a hygiene instructor, who asked them to pledge to brush their teeth twice a day for the rest of their lives. In Jane’s view, the promise would be impossible to keep, making the request absurd.
