Nano-Enhanced Fabrics Can Clean Themselves

(p. D3) Scientists in Australia, one of the sunniest places on the planet, have discovered a way to rid clothes of stubborn stains by exposing them to sunlight, potentially replacing doing the laundry.
Working in a laboratory, the researchers embedded minute flecks of silver and copper–invisible to the naked eye–within cotton fabric. When exposed to light, the tiny metal particles, or nanostructures, released bursts of energy that degraded any organic matter on the fabric in as little as six minutes, said Rajesh Ramanathan, a postdoctoral fellow at RMIT University, in Melbourne.
The development, reported recently in the journal Advanced Materials Interfaces, represents an early stage of research into nano-enhanced fabrics that have the ability to clean themselves, Dr. Ramanathan said. The tiny metal particles don’t change the look or feel of the fabric. They also stay on the surface of the garment even when it is rinsed in water, meaning they can be used over and over on new grime, he said.

“The Powers of a Man’s Mind Are Directly Proportioned to the Quantity of Coffee He Drinks”

(p. C9) . . . certain aspects of 18th-century Parisian life diluted the importance of sight. This was, after all, a time before widespread street lighting, and, as such, activities in markets (notably Les Halles) were guided as much by sound and touch as by eyes that struggled in the near dark conditions. Natural light governed the lives of working people, principally because candles were expensive. Night workers–such as baker boys known as “bats,” who worked in cheerless basements–learned to rely on their other senses, most notably touch.
. . .
“For Enlightenment consumers, a delicious food or beverage had more than just the power of giving a person pleasure,” writes Ms. Purnell; taste, it was held, could influence personality, emotions and intelligence. Take coffee, “the triumphant beverage of the Age of Enlightenm ent.” Considered a “sober liquor,” it stimulated creativity without courting the prospect of drunkenness. Sir James Mackintosh, the Scottish philosopher, believed that “the powers of a man’s mind are directly proportioned to the quantity of coffee he drinks.” Voltaire agreed and supposedly quaffed 40 cups of it every day. Taste was also gendered: Coffee was deemed too strong for women; drinking chocolate was thought more suitable.

Workers in Open Offices Are Less Able to Focus and Take More Sick Days

(p. R7) Noisy, open-floor plans have become a staple of office life. But after years of employee complaints, companies are trying to quiet the backlash.
Many studies show how open-plan office spaces can have negative effects on employees and productivity. As a result, companies are adding soundproof rooms, creating quiet zones and rearranging floor plans to appeal to employees eager to escape disruptions at their desk.
Companies are “not providing sufficient variety in spaces,” says David Lehrer, a researcher at the Center for the Built Environment at the University of California, Berkeley. Mr. Lehrer studies the impact of office designs on employees, and lack of “speech privacy” is currently a significant problem, he says. Employees in open-plan offices are less likely to be satisfied with their offices than employees in a traditional office layout, Mr. Lehrer adds.
. . .
Companies with open offices, . . . , soon encountered the downsides. For one thing, workers took increased sick days–a 2014 Swedish study of more than 1,800 workers found open-plan workers were twice as likely to take sick days as workers in traditional offices. The reason, the researchers hypothesized: the spread of germs and increased environmental stress of working in an open space. Workers also complained of an inability to focus and were generally less content with their work environment, the study said.
Now, companies are again “realizing people actually have to be productive,” says Ned Fennie, partner at San Francisco-based architecture firm Fennie + Mehl.

“Slow Is Smooth and Smooth Is Fast”

(p. B2) WASHINGTON — Jeff Bezos, the billionaire chief executive of Amazon, founded a rocket company as a hobby 16 years ago. Now that company, Blue Origin, finally has its first paying customer as it ramps up to become a full-fledged business.
Mr. Bezos announced that customer, the satellite television provider Eutelsat, on Tuesday. In about five years, Eutelsat, which is based in Paris, will strap one of its satellites to a new Blue Origin rocket to be delivered to space, a process it has done dozens of times with other space partners.
. . .
Blue Origin’s deal with Eutelsat is a “definite statement to the industry that Blue Origin will be a viable commercial launch vehicle,” said Carissa Bryce Christensen, the chief executive of Bryce Space and Technology, a consulting firm.
. . .
Mr. Bezos “is investing because he wants to transform people’s lives with space capabilities, but the expectation has always been that this will be a successful business,” Ms. Christensen said.
. . .
Mr. Bezos said he was approaching his space project with an abundance of patience.
“I like to do things incrementally,” he said, noting that Blue Origin’s mascot is a tortoise. With such high costs and risks with each rocket launch, it is important not to skip steps, he said.
“Slow is smooth and smooth is fast,” said Mr. Bezos, who also owns The Washington Post and a clock that will keep time for 10,000 years. “I’ve seen this in every endeavor I’ve been in.”

Seeking a “Safe Space” to Protect Taxpayers from Wasteful “Spending on Political Correctness”

(p. A1) WORCESTER, Mass. — A freshman tentatively raises her hand and takes the microphone. “I’m really scared to ask this,” she begins. “When I, as a white female, listen to music that uses the N word, and I’m in the car, or, especially when I’m with all white friends, is it O.K. to sing along?”
The answer, from Sheree Marlowe, the new chief diversity officer at Clark University, is an unequivocal “no.”
The exchange was included in Ms. Marlowe’s presentation to recently arriving first-year students focusing on subtle “microaggressions,” part of a new campus vocabulary that also includes “safe spaces” and “trigger warnings.”
. . .
(p. A3) In August [2016], the University of Wisconsin system, which includes the Madison flagship and 25 other campuses, said it would ask the State Legislature for $6 million in funding to improve what it called the “university experience” for students. The request includes money for Fluent, a program described as a systemwide cultural training for faculty and staff members and students.
But that budget request has provoked controversy. “If only the taxpayers and tuition-paying families had a safe space that might protect them from wasteful U.W. System spending on political correctness,” State Senator Stephen L. Nass, a Republican, said in a statement issued by his office, urging his fellow lawmakers to vote against the appropriation.
Mr. Nass’s objection to spending money on diversity training reflects a rising resistance to what is considered campus political correctness. At some universities, alumni and students have objected to a variety of campus measures, including diversity training; “safe spaces,” places where students from marginalized groups can gather to discuss their experiences; and “trigger warnings,” disclaimers about possibly upsetting material in lesson plans.
Some graduates have curtailed donations, and students have suggested that diversity training smacks of some sort of Communist re-education program.
The backlash was exemplified recently in a widely publicized letter sent to new freshmen at the University of Chicago by the dean of students, John Ellison.
He warned that the university did not “support so-called trigger warnings, we do not cancel invited speakers because their topics might prove controversial, and we do not condone the creation of intellectual safe spaces where individuals can retreat from ideas and perspectives at odds with their own.”

Panopticon: “Bentham’s Most Infamous Idea”

(p. C6) Perhaps the most fascinating chapter of the book, highlighting Mr. Crawford’s ability to mix philosophy and reporting, is the one about the panopticon. The idea of an annular building with a central observation tower was conceived by the philosopher Jeremy Bentham (1748-1832). The utilitarian is known most superficially by students of and visitors to University College, London, as the eccentric who willed that, after his death, his body be preserved seated on a chair in a glass case.
Mr. Crawford fleshes out the story, noting that, in fact, the smartly dressed Bentham figure that sits inside a glass display case today is actually a skeleton of the man, his head a wax replica of the real one that did not survive the preservation process. When I was a regular at University College one summer, I was told that the cabinet holding the “Auto-Icon” (Bentham’s term) was rolled over to the lecture hall on occasion, something that I don’t recall witnessing.
The author’s real purpose in discussing Bentham’s most infamous idea is to describe the utopian–or dystopian, depending upon one’s point of view–concept. In one embodiment, it took the form of a rimless wagon wheel, in which someone situated at the hub could oversee activities in all directions, making the layout ideal for insuring that workers in a factory did not take more breaks than allowed, inmates did not misbehave in a prison or students did not cheat on an exam.
Bentham’s insight was that the mere fact that those being observed knew that they were being watched would cause them to alter their behavior for the better. Could Bentham have imagined that his idea would form the foundation of our surveillance society? Looking at our culture today–with its CCTV, smartphones and so on–to some it surely seems that we live in a permanent panopticon. “All this,” Mr. Crawford writes, “from a ‘simple idea in architecture.’ “

For $9,000, No Chicken Need Die, When You Eat a Pound of Chicken

(p. B3) A Bay Area food-technology startup says it has created the world’s first chicken strips grown from self-reproducing cells without so much as ruffling a feather.
And the product pretty much tastes like chicken, according to people who were offered samples Tuesday [March 14, 2017] in San Francisco, before Memphis Meats Inc.’s formal unveiling on Wednesday.
Scientists, startups and animal-welfare activists believe the new product could help to revolutionize the roughly $200 billion U.S. meat industry. Their goal: Replace billions of cattle, hogs and chickens with animal meat they say can be grown more efficiently and humanely in stainless-steel bioreactor tanks.
. . .
On Tuesday [March 14, 2017], Memphis Meats invited a handful of taste-testers to a San Francisco kitchen and cooked and served their chicken strip, along with a piece of duck prepared à l’orange style.
Some who sampled the strip–breaded, deep-fried and spongier than a whole chicken breast–said it nearly nailed the flavor of the traditional variety. Their verdict: They would eat it again.
. . .
The cell-cultured meat startups are a long way from replacing the meat industry’s global network of hatcheries, chicken barns, feed mills and processing plants. But they say they’re making progress. Memphis Meats estimates its current technology can yield one pound of chicken meat for less than $9,000. That is half of what it cost the company to produce its beef meatball about a year ago. The startups, however, aspire to produce meat that can be cost-competitive with the conventionally raised kind.

As Consumers Accept Surge Pricing, More Will Accept Congestion Pricing Too

(p. B2) With remarkable consistency, the research finds the same thing: Whenever a road is built or an older road is widened, more people decide to drive more. Build more or widen further, and even more people decide to drive. Repeat to infinity.
Economists call this latent demand, which is a fancy way of saying there are always more people who want to drive somewhere than there is space for them to do it. So far anyway, nothing cities have done to increase capacity has ever sped things up.
The extent of this failure was chronicled in a 2011 paper called “The Fundamental Law of Road Congestion,” by the economists Gilles Duranton, from the Wharton School of the University of Pennsylvania, and Matthew Turner, from Brown University.
The two went beyond road building to show that increases in public transit and changes in land use — basically, building apartments next to office buildings so that more people can walk or bike to work — also fail to cut traffic (or do so only a little).
This doesn’t mean public transit and land planning are bad ideas, or that widening freeways is a bad idea. When roads are bigger, more people can get around. More people see family; more packages are delivered; more babies are lulled to sleep. It just means that none of those measures have done much to reduce commute times, and self-driving cars seem unlikely to either.
That’s where charging people during busy times comes in. “Maybe autonomous cars will be different from other capacity expansions,” Mr. Turner said. “But of the things we have observed so far, the only thing that really drives down travel times is pricing.”
This is because the average person prefers the privacy and convenience of riding in a car.
. . .
“This idea of congestion pricing is not completely dismissed the way it once was,” said Clifford Winston, an economist at the Brookings Institution.
Mr. Winston said the eventual introduction of self-driving cars would probably lessen consumer opposition to paying more to use roads during peak periods. Ride-hailing apps have taught consumers to accept surge pricing, and people are generally less resistant to paying for something new. The result would be something like variably priced lanes dedicated to fleets of robot vehicles.
If that happens, one of the hidden benefits of this revolutionary new technology will be that it got people to accept an idea that economists started talking about at least a century ago. And you get home a half-hour earlier.

Brits Saw America “as a Place to Dump Their Human Waste”

(p. 11) . . . , Isenberg — a historian at Louisiana State University whose previous books include a ­biography of Aaron Burr — provides a cultural ­history of changing concepts of class and inferiority. She argues that British colonizers saw their North American empire as a place to dump their human waste: the idle, indigent and criminal. Richard Hakluyt the younger, one of the many colorful characters who fill these pages, saw the continent as “one giant workhouse,” in ­Isenberg’s phrase, where the feckless poor could be turned into industrious drudges.

Muzzled Chinese Historian Dares to Publish Truth of Cultural Revolution

(p. 7) BEIJING — It seemed that China’s censors had finally muzzled Yang Jisheng, the famed chronicler of the Mao era. Last year, he had finished writing a widely anticipated history of the Cultural Revolution. But officials warned him against publishing it and barred him from traveling to the United States, he has said, and he stayed muted through the 50th anniversary of the start of that bloody upheaval.
Now Mr. Yang has broken that silence with the publication of his history of the Cultural Revolution, “The World Turned Upside Down,” a sequel to “Tombstone,” his landmark study of the famine spawned by Mao’s policies in the late 1950s. The 1,151-page book is the latest shot fired in China’s war over remembering, or forgetting, the dark side of its Communist past, a struggle that has widened under the hard-line president, Xi Jinping.
“I wrote this book to expose lies and restore the truth,” Mr. Yang writes in the book, which has been quietly published in Hong Kong, beyond the direct reach of Chinese censors. “This is an area that is extremely complicated and risky, but as soon as I entered it, I was filled with passion.”
Since Mr. Xi took power in 2012, the Communist Party authorities have denounced historians who question the party’s lionization of its past and exhume grim events like the Cultural Revolution, which Mao started in 1966, opening a decade of purges and bloodshed.
Tens of millions were persecuted and perhaps a million or more people were killed in that convulsive time. But officials say dwelling on such events is subversive “historical nihilism” aimed at corroding the party’s authority.
