getting smarter by injecting current to your skull
A few electrical pulses may miraculously increase your IQ? Too good to be true! Some research study may water down this cognitive-enhancement craze (so-called tDCS, transcranial direct-current stimulation) http://spectrum.ieee.org/biomedical/ethics/brain-hackers-beware-scientist-says-tdcs-has-no-effect
bias against women and the black to pursue advanced degrees?
顯然很多美國大學教授還是認為,女生和黑人不太具有讀博士班的天份 (但亞洲人沒有這個困擾)。 這是美國大學教授的偏見還是根深蒂固的文化使然?

pick up rich parents to learn 32M more words before age 4
The link between parental income and a child's academic success has grown stronger than ever before. The assets that rich parents pass on to their children are invulnerable to inheritance tax; it is the "brains". Children of professionals hear 32M more words by the age of four than those of parents on welfare. Only rich families's children or very clever kids from poor families benefit from the as-is U.S. education system. All others are relegating to the marginal in this society.

No betrayal from the pitch and volume of your speech
If you have (or pretend to have) power or authority, your speech becomes sturdier in pitch and more varied in volume. Probably a perfect mindset during interview or when giving a presentation.

higher test scores by longhand note taking
Take class notes by laptop may be very handy but it is at the expense of lowering your test scores, especially the conceptual questions, compared with the longhand note takers.

tender moments enhance baby's cognitive development
It is well-known that early constructive stimuli to babies have immense impact for their later formative cognitive development. However, it is still to my surprise the huge extent of the dependence of environment on the exponential increase of the neural synaptic connections in baby's brain. Any tender moments between parents and babies are implicitly enhancing the baby's future cognitive development.

Sisyphean task to map humanity's neuron network
It is expected to take more than 10 years from the best minds on this planet just to map the neuron networks of a fruit fly's brain. To have a complete map of the inscrutable humanity's brain neuron networks may take many generations, if possible. http://www.nytimes.com/2015/01/11/magazine/sebastian-seungs-quest-to-map-the-human-brain.html

crazy school with 16-hour class time every day
整個城市沒有電動玩具店,沒有網咖,沒有彈子房, 市政府關閉全部娛樂性質的店,唯一的目標就是拼高考。 安徽毛坦廠中學兩萬學生,每天的第一堂課早上6點20分,最後一堂課晚上10點50分。 一個禮拜7天只有三個小時的休息時間。 這種瘋狂似的教育當然會有好成績,16年前整個學校通過高考最低分的只有98人,去年已經超過一萬人. 不過他們至少不像湖北的一所學校,學生在課堂上要打點滴以儲備精力考高考。http://www.nytimes.com/2015/01/04/magazine/inside-a-chinese-test-prep-factory.html

There is no greater joy in life than giving
Another philanthropic story from Forbes#180 Marc Benioff who has persistently dedicated to the education and the children's health. His company's employees are encouraged to "adopt" schools in community service, just the same exhortations he gives to the other tech entrepreneurs. "There is no greater joy in life than giving," said Benioff.
