While adolescent girls and boys text at the same rates, girls tend to text more compulsively than boys—and their grades might suffer as a result, a new study found. TIME reports.
The Pew Research Center study of Millennial communication habits, published in the American Psychological Association’s Psychology of Popular Media journal, found that texting is hugely popular among teenagers, with 63% of teens reporting they send and receive an average of 167 texts per day. (Only 35% report socializing face-to-face outside of school.)
3DPrintingNike’s COO thinks we could soon 3D print Nike sneakers at home
Eric Sprunk, Nike’s COO, talked about the innovation in Nike’s Flyknit technology and what it suggests about the way sneakers could be made in the future. Based on what Nike is already doing with Flyknit, Sprunk says the ability for consumers to 3D print a pair of sneakers is close at hand. [via Quartz]
The way it might work goes something like this: You could head to Nike’s website, customize a sneaker to your specifications, and buy a file containing the instructions for the 3D printer. If you have a printer at home, you could print it yourself and have a new pair of sneakers in a matter of hours. If you don’t, you could take the file to a Nike store and have them print it for you.

The Good DroneDJI announces agricultural drone designed to spray crops
DJI's latest model, an eight-rotor Agras MG-1 is designed for spraying crops, with the ability to cover between seven and ten acres an hour and a tank that holds 10 liters (about 2.6 gallons) of liquid. [via The Verge]
DJI says the Agras is over 40 times more efficient than manual spraying. Using a microwave radar, the drone can scan the ground below and maintain the right distance from crops to spray the correct amount of liquid. It flies up to eight meters per second, modulating its spraying for even coverage. It can be used in automatic, semi-automatic, or manual operation, and is designed for durability with dustproofing, water resistance, and an anti-corrosive build. The Agras also folds down into a compact package after use.
