The earth’s countryside is emptying out, more quickly all the time. It took about 10,000 years for the human population to become 3 percent urban — a period extending roughly from the dawn of human settlement until 1800. A century later, Earth was still just 14 percent urban. But in 2007, the United Nations announced we’d crossed a monumental threshold. For the first time, more than 50 percent of the world lived in cities rather than rural villages and farms. By 2030, some projections say more than 80 percent of humanity will be urban, with many inhabiting the slum-choked cities of the developing world.
The “toy” in this case was a handheld laser, purchased online by a 15-year-old Swiss boy. According to a letter published in today’s New England Journal of Medicine, the boy had ordered a laser pointer with a green light “to use as a toy for popping balloons from a distance and burning holes into paper cards and his sister’s sneakers.”
Japan that a person’s ABO blood type or ketsueki-gata (血液型?) is predictive of their personality, temperament, and compatibility with others. Ultimately deriving from ideas of historical scientific racism, the popular belief originates with publications by Masahiko Nomi in the 1970s. The scientific community dismisses such beliefs as superstition or pseudoscience.
The second part is a little more interesting, however, it implies that a certain form of stimulation embeddable in a popular game or internet service (I think they’re too shy too to say porn) might reduce cognitive performance by only a fraction, but when considered over a whole army, it could make a difference to the overall fighting force. The scenario is a little bit science fiction (Snow Crash anyone?) but is an intriguing possibility given that only a slight change would be needed in an individual to justify its effect if it could be distributed over a wide enough population. For example, many priming studies have shown it is possible to influence behaviour just by exposing people to certain concepts. In one of my favourite studies, exposing people to ideas about elderly people slowed their walking speed, while a more recent experiment found this effect could change action sequences as well.
During the illusion, a participant’s hand is hidden, and a rubber hand positioned so that it appears as her own. She knows that it’s fake — but when both hands are stroked simultaneously, what’s seen and felt becomes blurred. Suddenly the rubber hand literally feels like it belongs to her. Consciously she knows it’s not true, but that doesn’t matter. Threaten the fake hand, and people under the illusion’s spell respond as if their own hands were threatened.
Cannabis smokers often report that when stoned, their thoughts have a free-wheeling quality and concepts seem connected in unusual and playful ways. A study just published online in Psychiatry Research suggests that this effect may be due to the drug causing ‘fast and loose’ patterns of spreading activity in memory, something known as ‘hyper-priming’.
Based on surveys Barnes collected, the top five worries of parents are, in order:
2. School snipers
4. Dangerous strangers
But how do children really get hurt or killed?
1. Car accidents
2. Homicide (usually committed by a person who knows the child, not a stranger)
