Wireless Power: Experiments in Charging Future Mobile Devices

Scientists and engineers are working towards making wireless power possible by harvesting and transforming existing energy from the world around us. Models they have looked at include nanoscale pillars that turn waste heat into electricity and a spongey smartphone case that generates electricity from sitting on a vibrating surface. One source of energy is thermoelectricity, which works by creating electricity from the current created by electrons moving from hot to cold, an approach that may be ideal for humans.

Twitter Makes Its Data Available to Academics with New Grant

Through its new Data Grants program, Twitter is opening its archives to academics who want access to the data — and it’s all free. The data goes back to 2006, and social scientists and researchers can submit applications until March 15th to request access to old tweets. Until now, Twitter has only made this data available to partner companies for a fee starting at $500 a month. Twitter previously worked with Johns Hopkins University to predict where flu outbreaks will hit; this project hopes to make similar research possible.

Study of Facebook Language Leads to Groundbreaking Results

A group of researchers from the University of Pennsylvania conducted a study through which they carefully analyzed the Facebook statuses of 75,000 volunteers. The volunteers all took a personality questionnaire and made their Facebook posts available to researchers who searched for linguistic patterns. In analyzing the Facebook posts, researchers were able to determine a surprising amount of information about each individual.
