A plastic screen that rolls up and doesn’t crack when you drop it may sound like science fiction, but the Flexible Display Center at Arizona State University is investing millions to liberate electronic devices from the constraints of rigid glass.
And reality could come sooner than you think. The project was initiated by the U.S. Army in cooperation with a number of companies, including Boeing and Hewlett-Packard, to expedite the development of the technology.
“Flexible … black-and-white screens for e-readers are very close to commercialization,” said Nick Colaneri, Flexible Display Center director. Black-and-white screens are less complicated to create, and he estimates flexible screens capable of rolling up and displaying color images are three to five years away.

“The government says … TV dramas shouldn’t have characters that travel back in time and rewrite history. They say this goes against Chinese heritage,” reports CNN’s Eunice Yoon. “They also say that myth, superstitions and reincarnation are all questionable.”

The common view that drinking is bad for learning and memory isn’t wrong, says neurobiologist Hitoshi Morikawa, but it highlights only one side of what ethanol consumption does to the brain.
“Usually, when we talk about learning and memory, we’re talking about conscious memory,” says Morikawa, whose results were published last month in The Journal of Neuroscience. “Alcohol diminishes our ability to hold on to pieces of information like your colleague’s name, or the definition of a word, or where you parked your car this morning. But our subconscious is learning and remembering too, and alcohol may actually increase our capacity to learn, or ‘conditionability,’ at that level.”
Morikawa’s study, which found that repeated ethanol exposure enhances synaptic plasticity in a key area in the brain, is further evidence toward an emerging consensus in the neuroscience community that drug and alcohol addiction is fundamentally a learning and memory disorder.

For centuries, children wore dainty white dresses up to age 6. “What was once a matter of practicality—you dress your baby in white dresses and diapers; white cotton can be bleached—became a matter of ‘Oh my God, if I dress my baby in the wrong thing, they’ll grow up perverted,’ ” Paoletti says.
The march toward gender-specific clothes was neither linear nor rapid. Pink and blue arrived, along with other pastels, as colors for babies in the mid-19th century, yet the two colors were not promoted as gender signifiers until just before World War I—and even then, it took time for popular culture to sort things out.
In 1927, Time magazine printed a chart showing sex-appropriate colors for girls and boys according to leading U.S. stores. In Boston, Filene’s told parents to dress boys in pink. So did Best & Co. in New York City, Halle’s in Cleveland and Marshall Field in Chicago.
Today’s color dictate wasn’t established until the 1940s, as a result of Americans’ preferences as interpreted by manufacturers and retailers. “It could have gone the other way,” Paoletti says.
