“What is the color of the Universe? This seemingly simple question has never  been answered by astronomers until now.”

It is arguable whether history is made by great men and women or vice versa, but undoubtably social connections shape history. Analysing Wikipedia, a global collective memory place, we aim to understanding how social interactions are recorded across cultures. We focus on the social networks of persons with biographical articles on the 15 largest language Wikipedias. We detect the most influential historical characters in these networks and point out culture-related peculiarities. Moreover, we reveal remarkable similarities between different groups of language Wikipedias and shared knowledge about social connections across cultures.

Without diminishing learning outcomes, automated teaching software can reduce the amount of time professors spend with students and could substantially reduce the cost of instruction, according to new research.
In experiments at six public universities, students assigned randomly to statistics courses that relied heavily on “machine-guided learning” software -- with reduced face time with instructors -- did just as well, in less time, as their counterparts in traditional, instructor-centric versions of the courses. This largely held true regardless of the race, gender, age, enrollment status and family background of the students.
