An insect's eye lets it see really well because each of its light-sensitive cells has a dedicated lens. This miniature camera, which mimics an insect eye, is made from an array of microlenses arranged on a stretchable sheet that can be inflated like a balloon to a hemispherical shape.
A smartphone can tell you where to get a cup of coffee, but it can't go get the coffee for you. Engineers would like to build little machines that can do stuff. They would be useful for a lot more than coffee, if we could figure out how to make them work.
But the rules of mechanics change at small scales. Friction becomes dominant; turbulence can upend a small airplane.

Employers using the E-Verify program are required to post an E-Verify Participation Poster, shown here in a handout photo. A Senate bill would make participation in the system, used to check employees' immigration status, mandatory for all employers.
Some employers around the nation have been using E-Verify to check the immigration status of employees for years. Operated by the Department of Homeland Security, the online system is designed to make it harder to hire unauthorized workers — and harder for those workers to find jobs.
While participation in the program has been voluntary since 1996, the immigration bill now in the Senate would make E-Verify mandatory.
Jordan's fastest-growing city lies in the middle of the desert, where the sand is so white that from a distance it looks like snow. There's little running water and not much electricity.
The name of this place? The Zaatari refugee camp, home to more than 100,000 Syrian refugees.
"This is a city — not one that anybody would want to create if they had a choice," says Caroline Gluck of Oxfam, one of the aid agencies working in the Zaatari camp. "It's certainly not urban planning at its best."
Colorado Governor John Hickenlooper, center, exits the Fort Lyon Correctional Facility in Las Animas, Colo., on Wednesday after touring the facility. Hickenlooper has proposed closing the facility due to budget concerns.
The government of Kazakhstan says it's cooperating with U.S. officials in the investigation of the Boston Marathon bombings, a day after two men from the Central Asian country were charged in connection with the blasts that killed three people and wounded more than 250.
A garment factory that manufactures products for international clothing companies collapsed outside of Dhaka, Bangladesh, last month, killing more than 400 workers and injuring scores of others. It came on the heels of a fire at another factory in November 2012; that incident killed 112 workers.
Factories like these in Bangladesh pump out what author Elizabeth Cline calls "fast fashion," or clothes made on the cheap by big chains such as H&M, Zara, Esprit, Lee, Wrangler, Nike, J.C. Penney and Wal-Mart.
Mexican Piggy Cookies are known by many names — cerditos, cochinitos, marranitos or puerquitos. Sweetened with unprocessed cane sugar and honey, and spiced with cinnamon, the cutout cookies puff when you bake them.
For years, many marine biologists have argued that the floating, open-ocean net pens that produce billions of pounds of salmon per year also generate pollution, disease and parasites.
In some places in western Canada, the open-ocean salmon farming industry has been blamed for the collapse of wild salmon populations in the early 2000s — though other research has challenged that claim.
