Facebook’s Profit Propelled by Mobile

Facebook, based in Menlo Park, Calif., said it had about 1.32 billion monthly users around the world in June, with more than a billion of those people using the service at least partly on mobile devices.
Revenue was $2.91 billion, up 61 percent from $1.81 billion during the same period last year.
Mobile devices accounted for nearly two-thirds of Facebook’s revenue, which at this point mostly comes from ads shown on the Facebook website and apps. However, the company is beginning to supplement that with ads on other sites.
... The company accounted for 5.8 percent of the world’s estimated $120 billion in digital ad revenues in 2013, and it captured 17.77 percent of mobile ad spending, according to the research firm eMarketer.
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.
