Children who received at least three years (M = 4.6 years) of instrumental music training outperformed their control counterparts on two outcomes closely related to music (auditory discrimination abilities and fine motor skills) and on two outcomes distantly related to music (vocabulary and nonverbal reasoning skills). Duration of training also predicted these outcomes. Contrary to previous research, instrumental music training was not associated with heightened spatial skills, phonemic awareness, or mathematical abilities

Chinese Premier Li Keqiang finished his four country tour of Africa, making stops in Ethiopia (including the African Union headquarters), Nigeria, Angola, and Kenya. China’s activities in Africa are increasingly gaining media attention around the world, particularly as speculation heats up about a competition for the continent between China and the U.S. (or even China and Japan).

Li promised to devote “more than half of its foreign aid to Africa,” with no conditions attached to the funding. Li pledged China’s friendship to Africa, and reiterated Chinese support for Africa playing a larger role in world politics as it continues to develop. Li also stressed that China “will never attach political conditions to its assistance to Africa and will never use its aid programs to interfere in the internal affairs of African countries,” a tacit criticism of Western countries who often refuse to provide funding to countries seen as human rights violators.

Li Keqiang also acknowledged in a speech that China-Africa relations have encountered some “growing pains,” a nod to tensions in some African countries over issues such as illegal Chinese mining operations and resentment against local Chinese traders. But Xinhua was quick to emphasize that these “growing pains” are “problems that inevitably occur during the development of relations” — meaning no one (especially not China) is to blame.

Doctor X is a trained physician that works on harm reduction projects in real life but helps Silk Road users in his free time by providing answers to any of their questions—all for free. He started in June 2013, and received 600 questions and 5,000 visits after just three months. In an interview with Joseph Cox of Vice, Doctor X said: "Drug users need more...They need answers, and that's what I try to provide. People ask me about the real risks and adverse effects, drug combinations [illegal and prescriptive] and the use of drugs in persons suffering from different conditions, such as diabetes or neurological problems."

our brains actually respond differently to happy and sad music

hat after hearing a short piece of music, participants were more likely to interpret a neutral expression as happy or sad, to match the tone of the music they heard.

moderate noise levels increase processing difficulty which promotes abstract processing, leading to higher creativity

Pandora (which is also the name of the company) grew out of the Music Genome Project, which company founder Tim Westergren began six years ago.

He became fascinated with the way directors described the music they were looking for, which led to his wondering what made people enjoy certain types of music. He asked himself, "If people haven't found any music that they love since college, and artists are struggling to find an audience, is there a role for technology to help bridge the gap?"

Westergren started the Genome Project from the idea of creating a platform for connecting people with music that they'll love based on music they already enjoy. The project uses experts called "music analysts" to deconstruct music into its fundamental parts and capture the results into a database. Pandora has 40 professional musicians who come to the office every day and listen to one song at a time, analyzing each in anywhere from 200 to 400 dimensions. (The dimensions are somewhat different for each genre of music.)
