Smartphones Surpass Computers for Internet Use in China
For the first time, more Chinese people are gaining access to the Internet with mobile phones than with personal computers, reports The New York Times.
The shift is significant, if expected, in China, which is the world’s biggest market for both Internet and smartphone users.
China had 632 million Internet users at the end of June, an increase of 14.4 million since the end of December, according to a semiannual report published on Monday by the official China Internet Network Information Center, which is known as CNNIC. Of those, 83.4 percent reported gaining access to the Internet with mobile phones, exceeding for the first time the 80.9 percent who reported using computers to go online.

MIT students make 3D-printed ice cream
If your ice cream could look like anything in the world, what would you choose? A new machine could 3D print your ice cream in 15 minutes. The Guardian reports.
Three students from MIT have hacked together a 3D printer that can produce edible Mr Whippy-style ice cream in any shape.
Kyle Hounsell, Kristine Bunker and David Donghyun Kim developed the contraption – a modified version of an existing 3D printer connected to a “soft serve” ice-cream machine – as part of a graduate project in MIT’s additive manufacturing department.
The students built a cooling system using liquid nitrogen to fix the ice cream in place as it was squirted out of the 3D printer’s nozzle into the desired shape. The instant cooling allowed the printer to build up the ice cream layers just as a traditional extrusion-based 3D printer squirts down layers of plastic.
“The main reason we feel an ice cream 3D printer is an important addition to current additive manufacturing technology is that it interests children,” the MIT students explained.
The students had to balance the accuracy and printing resolution of the printer to enable interesting shapes and creations with the speed of printing, as no one wants to wait 30 minutes for their ice cream to appear.

Can Drones Fight Illegal "Pirate" Fishing?
Conservationists test unmanned aerial vehicles in Belize and California. National Geographic reports.
An estimated 20 percent of all fish hauled in around the globe are caught illegally, through a combination of fishing in restricted areas, subverting quotas and seasonal limits, and using banned gear. The fish are shipped around the world and sold to existing markets, where most buyers have no idea that the food they are purchasing is stolen goods.
The problem is especially acute in Belize, where hundreds of incidents have been reported over the past few years, according to Julio Maaz, who serves as a fisheries coordinator in Belize with the U.S.-based Wildlife Conservation Society.
Belize has only 70 fisheries enforcement officers to patrol its 240 miles (386 kilometers) of Caribbean coast and more than 200 islands. And with fuel prices rising, the enforcement budget has been shrinking. As a result, fishermen get away with flouting the law, says Maaz—especially crews based in nearby Honduras and Guatemala.
But now a new weapon is being tested in the fight against pirate fishing: drones.
