How Air Conditioning Can Improve Metabolism

(p. 14) Sleep is essential for good health, as we all know. But a new study hints that there may be an easy but unrealized way to augment its virtues: lower the thermostat. Cooler bedrooms could subtly transform a person’s stores of brown fat — what has lately come to be thought of as “good fat” — and consequently alter energy expenditure and metabolic health, even into daylight hours.
. . .
“These were all healthy young men to start with,” . . . [senior author Francesco S. Celi] says, “but just by sleeping in a colder room, they gained metabolic advantages” that could, over time, he says, lessen their risk for diabetes and other metabolic problems. The men also burned a few more calories throughout the day when their bedroom was chillier (although not enough to result in weight loss after four weeks).
. . .
The message of these findings, Celi says, is that you can almost effortlessly tweak your metabolic health by turning down the bedroom thermostat a few degrees. His own bedroom is moderately chilled, as is his office — which has an added benefit: It “keeps meetings short.”

Serendipitous Discovery that Titanium Fuses with Bone, Leads to Implants

(p. 24) Implants have been a major advance in dentistry, liberating millions of elderly people from painful, ill-fitting dentures, a diet of soft foods and the ignominy of a sneeze that sends false teeth flying out of the mouth. But addressing those problems was not Dr. Branemark’s initial intent.
At the start of his career, he was studying how blood flow affects bone healing.
In 1952, he and his team put optical devices encased in titanium into the lower legs of rabbits in order to study the healing process. When the research period ended and they went to remove the devices, they discovered to their surprise that the titanium had fused into the bone and could not be removed.
Dr. Branemark called the process “osseointegration,” and his research took a whole new direction as he realized that if the body could tolerate the long-term presence of titanium, the metal could be used to create an anchor for artificial teeth.
. . .
. . . , Dr. Branemark’s innovation was poorly received. After Dr. Branemark gave a lecture on his work in 1969, Dr. Albrektsson recalled, one of the senior academics of Swedish dentistry rose and referred to an article in Reader’s Digest describing Dr. Branemark’s research, adding, “This may prove to be a popular article, but I simply do not trust people who publish themselves in Reader’s Digest.”
As it happened, that senior academic was well known to the Swedish public for recommending a particular brand of toothpick. So Dr. Branemark immediately rose and struck back, saying, “And I don’t trust people who advertise themselves on the back of boxes of toothpicks.”

Congress Appropriates Funds to Test Concussion Theory of Rain

(p. 190) the first century A.D., when the Greek moralist Plutarch came up with the notion that rain followed military battles. Napoleon believed as much and fired cannons and guns at the sky to muddy up the ground between him and his attackers. Civil War veterans who wallowed in cold slop believed that ceaseless, close-range artillery fire had opened up the skies. In the late 1890s, as the first nesters started to dig their toeholds on the dry side of the one hundredth meridian, Congress had appropriated money to test the concussion theory in Texas. The tests were done by a man named Dyrenforth. He tried mightily, with government auditors looking over (p. 191) his shoulder, but Dyrenforth could not force a drop from the hot skies of Texas. From then on, he was called “Dry-Henceforth.”
Government-sponsored failure didn’t stop others from trying. A man who called himself “the moisture accelerator,” Charles M. Hatfield, roamed the plains around the turn of the century. A Colonel Sanders of rainmaking, Hatfield had a secret mixture of ingredients that could be sent to the sky by machine. In the age before the widespread use of the telephone, it was hard to catch up with the moisture accelerator after he had fleeced a town and moved on.

Ways Technology May Decrease Inequality

(p. 7) As the previous generation retires from the work force, many more people will have grown up with intimate knowledge of computers. And over time, it may become easier to work with computers just by talking to them. As computer-human interfaces become simpler and easier to manage, that may raise the relative return to less-skilled labor.
The future may also extend a growing category of employment, namely workers who team up with smart robots that require human assistance. Perhaps a smart robot will perform some of the current functions of a factory worker, while the human companion will do what the robot cannot, such as deal with a system breakdown or call a supervisor. Such jobs would require versatility and flexible reasoning, a bit like some of the old manufacturing jobs, but not necessarily a lot of high-powered technical training, again because of the greater ease of the human-computer interface. That too could raise the returns to many relatively unskilled workers.

As with Airplanes, Lives Must Be Risked to Achieve Routine Safety in Spaceships

(p. A21) SEATTLE — ONE clear winter day in 1909, in Hampshire, England, a young man named Geoffrey de Havilland took off in a twin-propeller motorized flying machine of his own design, built of wood, piano wire and stiff linen hand-stitched by his wife. The launch was flawless, and soon he had an exhilarating sensation of climbing almost straight upward toward the brilliant blue sky. But he soon realized he was in terrible trouble.
The angle of ascent was unsustainable, and moments later de Havilland’s experimental plane crashed, breaking apart into a tangled mass of shards, splinters and torn fabric, lethal detritus that could easily have killed him even if the impact of smashing into the ground did not. Somehow, he survived and Sir Geoffrey — he was ultimately knighted as one of the world’s great aviation pioneers — went on to build an astonishing array of military and civilian aircraft, including the world’s first jet airliner, the de Havilland Comet.
I thought immediately of de Havilland on Friday when I heard that Virgin Galactic’s SpaceShipTwo, a rocket-powered vehicle designed to take well-heeled tourists to the edge of space, had crashed on a flight over the Mojave Desert, killing one test pilot and seriously injuring the other.
. . .
Certainly the Wright brothers and others like de Havilland were involved in what we now view as an epic quest, but many experts of the day were certain that flight, however interesting, was destined to be not much more than a rich man’s hobby with no practical value.
“The public has greatly over-estimated the possibilities of the aeroplane, imagining that in another generation they will be able to fly over to London in a day,” said a Harvard expert in 1908. “This is manifestly impossible.” Two other professors patiently explained that while laymen might think that “because a machine will carry two people another may be constructed that will carry a dozen,” in fact “those who make this contention do not understand the theory of weight sustentation in the air.”
. . .
There will be tragedies like the crash of SpaceShipTwo and nonlethal setbacks such as the fiery explosion, also last week, of a remote-controlled rocket intended for a resupply mission to the International Space Station. There will be debates about how to improve regulation without stifling innovation. Some will say private industry can’t do the job — though it’s not as if the NASA-sponsored Apollo or space shuttle missions went off without a hitch (far from it, sadly).
But at the heart of the enterprise there will always be obsessives like Sir Geoffrey, who forged ahead with his life’s work of building airplanes despite his own crash and, incredibly, the deaths of two of his three sons while piloting de Havilland aircraft, one in an attempt to break the sound barrier. Getting to routine safety aloft claimed many lives along the way, and a hundred years from now people will agree that in that regard, at least, spaceships are no different from airplanes.

Leading Computability Expert Says Humans Can Do What Computers Cannot

(p. B4) What does Turing’s research tell us?
“There is some scientific basis for the view that humans are doing something that a machine isn’t doing–and that we don’t even want our machine to do,” says S. Barry Cooper, a mathematician at Leeds and the foremost scholar of Turing’s work.
The math behind this is deep, but here’s the short version: Humans seem to be able to decide the validity of statements that should stump us, were we strictly computers as Turing described them. And since all modern computers are of the sort Turing described, well, it seems that we’ve won the race against the machines before it’s even begun.
. . .
The future of technology isn’t about replacing humans with machines, says Prof. Cooper–it’s about figuring out the most productive way for the two to collaborate. In a real and inescapable way, our machines need us just as much as we need them.

Esther Dyson Sees a Lot of Silicon Valley as Just Motivated to Make Money

(p. C11) The U.S. Commerce Department recently said that it plans to relinquish its oversight of Icann, handing that task to an international body of some kind. The details are still being worked out, but Ms. Dyson hopes that governments won’t be the new regulators. . . .
For now, she thinks there are many Silicon Valley Internet companies with inflated market values. “There is the desire to make money that motivates a lot of that in Silicon Valley, and yes, I think it’s totally a bubble,” she says. “It’s not like the last bubble in that there are a lot of real companies there [now], but there are a lot of unreal companies and…many of them will disappear.” She thinks too many people are starting similar companies. “You have people being CEOs of teeny little things who would be much better as marketing managers of someone else’s company,” she says.
And though her work often takes her to California, she’s happy to stay in New York. These days, she finds Silicon Valley “very fashionable,” she says, “and I don’t really like fashion.”

Japanese Try to Sell the iPhone of Toilets in United States

(p. B8) TOKYO–Yoshiaki Fujimori wants to be the Steve Jobs of toilets.
Like iPhones, app-packed commodes are objects of desire in Mr. Fujimori’s Japan. The lids lift automatically. The seats heat up. Built-in bidets make cleanup a breeze. Some of them even sync with users’ smartphones via Bluetooth so that they can program their preferences and play their favorite music through speakers built into the bowl.
Three-quarters of Japanese homes contain such toilets, most of them made by one of two companies: Toto Ltd., Japan’s largest maker of so-called sanitary ware, or Lixil Corp., where Mr. Fujimori is the chief executive.
Now Mr. Fujimori is leading a push to bring them to the great unwashed. In May, Lixil plans to add toilets with “integrated bidets” to the lineup of American Standard Brands, which Lixil acquired last year for $542 million, including debt.
. . .
Few people realized they needed smartphones until Apple’s iPhone came along. So it will be in the U.S. with American Standard’s new toilets, Mr. Fujimori said.
“Industry presents iPhone–industry presents shower toilet,” Mr. Fujimori said in an interview at Lixil’s headquarters in Tokyo. “We can create the same type of pattern.”
. . .
Mr. Fujimori maintained that once American consumers try such toilets, they won’t go back.
“This improves your standard of living,” he said. “It doesn’t hurt you. People like comfort, they like ease, they like automatic. And people like clean.”

High Skill Foreign Workers Raise Wages for Native Workers

Source of graph: online version of the WSJ article quoted and cited below.

(p. A6) “A lot of people have the idea there is a fixed number of jobs,” said . . . , Giovanni Peri of the University of California, Davis. “It’s completely turned around.”

Immigrants can boost the productivity of the overall economy, he said, “because then the pie grows and there are more jobs for other people as well and there’s not a zero-sum trade-off between natives and immigrants.”
Mr. Peri, along with co-authors Kevin Shih at UC Davis, and Chad Sparber at Colgate University, studied how wages for college- and noncollege-educated native workers shifted along with immigration. They found that a one-percentage-point increase in the share of workers in STEM fields raised wages for college-educated natives by seven to eight percentage points and wages of the noncollege-educated natives by three to four percentage points.
Mr. Peri said the research bolsters the case for raising, or even removing, the caps on H-1B visas, the program that regulates how many high-skilled foreign workers employers can bring into the country.

“Folkman Persisted in His Genuinely Original Thinking”

(p. 141) As detailed by Robert Cooke in his 2001 book Dr. Folkman’s War, the successful answers to these basic questions took Folkman through diligent investigations punctuated by an astonishing series of chance observations and circumstances. Over decades, Folkman persisted in his genuinely original thinking. His concept was far in advance of technological and other scientific advances that would provide the methodology and basic knowledge essential to its proof, forcing him to await verification and to withstand ridicule, scorn, and vicious competition for grants. Looking back three decades later, Folkman would ruefully reflect: “I was too young to realize how much trouble was in store for a theory that could not be tested immediately.”

Feds Allow Hollywood to Use Drones

(p. B1) LOS ANGELES — The commercial use of drones in American skies took a leap forward on Thursday [Sept. 25, 2014] with the help of Hollywood.
The Federal Aviation Administration, responding to applications from seven filmmaking companies and pressure from the Motion Picture Association of America, said six of those companies could use camera-equipped drones on certain movie and television sets. Until now, the F.A.A. has not permitted commercial drone use except for extremely limited circumstances in wilderness areas of Alaska.
Put bluntly, this is the first time that companies in the United States will be able to legally use drones to fly over people.
The decision has implications for a broad range of industries including agriculture, energy, real estate, the news media and online retailing. “While the approval for Hollywood is very limited in scope, it’s a message to everyone that this ball is rolling,” said Greg Cirillo, chairman of the aviation practice at Wiley Rein, a law firm in Washington.
Michael P. Huerta, the administrator of the F.A.A., said at least 40 similar applications were pending from companies beyond Hollywood. One is Amazon, which wants permission to move forward with a drone-delivery service. Google has acknowledged “self-flying vehicle” tests in the Australian outback.
“Today’s announcement is a significant milestone in broadening commercial use,” Anthony R. Foxx, secretary of transportation, told reporters in a conference call.
