3. Not until recently anyway. But scientists at Weill Cornell Medical College have at last managed to—at least with mice and monkeys. This produced artificial retinas, whose chips convert images into electronic signals and whose tiny projectors convert electronic signals into light.
4. TextPride was a fine business, but a tiny one. Meanwhile, the market for messaging apps was exploding. Facebook FB 0.61% bought WhatsApp for $19 billion; that service now has 700 million monthly active users. Tango, an app with 250 million registered users, is worth $1.5 billion. Kik has 200 million registered users. Snapchat, worth $10 billion, has 100 million users. A new study, commissioned by Kik, shows that U.S. users now spend more time on average in messaging apps than they do on social networking apps. The only problem?

2. "They say: 'I wonder why she kept her head down in the meeting; I wonder why she's not eager to take over that project; I wonder why she's leaving early a couple days a week," Kay says. "You're planting questions in their head."
3. Aspiring young leaders already place more emphasis on using their influence, rather than trying to exert power through the embedded authority of their position or their assigned title. Many are already gaining leadership experience, not through promotion at established institutions but by running bottom-up movements and voluntary groups, or by shaping their own start-ups.
Take the intriguing reintroduction of “unfeigned regards” — last big in the 18th century and now found on emails from Indian help centres. But the winning sign-off, at the bottom of a message sent one Friday, was: “weekend well”. I nearly awarded it second prize for the best noun pretending to be a verb, though at the last minute this award was snatched by a consultant overheard saying: “Can we cold towel that?”
