What is the attitude of the author toward the Webcast of the results from the Cryogenic Dark Matter Search?

    All the latest footwear engineering in your running sneakers might not mean a thing when it comes to preventing injuries. The latest barefoot running study in the journal Nature deployed 3-D infrared tracking to gauge the difference in foot strike between shod and shoeless runners. Scientific American reports.

   Runners who wore sneakers ended up landing heel-first 75 to 80 percent of the time. By contrast, barefoot runners usually land toward the middle or front of the foot—a dramatic difference that recalls the more natural foot strike of early Homo sapiens. Needless to say, early humans certainly were not bom to run wearing Nike or Reebok.

   “Most people today think barefoot running is dangerous and hurts.” said Daniel Lieberman, a professor of human evolutionary biology at Harvard University and lead author on the study. “But actually you can run barefoot on the world’s hardest surfaces without the slightest discomfort and pain.”

    More bad news for sneakers came last December, when the American Academy of Physical Medicine and Rehabilitation found that running shoes can increase joint torques at the hip, knee and ankle. Their study suggested that even going for a run in high heels was better for preventing joint injuries than tennis shoes.

The urban poor gained from the lower prices and greater supplies of food but the rural poor, especially the landless, have sometimes been disadvantaged. However, new agricultural technology should not be expected to stand proxy for social reform, and Lipton concludes that the technology per se (本身)was not to blame for the inequalities of impact; it met the criteria he would have specified for a technology to help the rural poor. As Frankel commented: ‘It is precisely the social blindness of modem technology that is encouraging the most disadvantaged scciion of the agricultural community’.

Such multi-set families may (36) family members in the same house, but that (37) brings them “together.” In fact, family outings—hiking, going to the (38), going out to dinner—are often limited by TV (39) one or more family members don’t want to go: “I’ll miss my (40),” is the common complaint.
