| Brain's gender makeup a gray (matter) area | | Posted Thursday, October 19, 2006 2:59:38 PM by Blog57 Team | | SAUSALITO, Calif. -- According to pop psychiatrist Louann Brizendine, author of the bestselling new book "The Female Brain," men and women come equipped with completely different operating systems -- not only below the belt but between the ears. Like bath towels, there are his-and-her brains. Or so Brizendine interprets the latest skull scanning: Woman is weather, "constantly changing and hard to predict." And man? Man is mountain.

According to the research results of the team led by David Greenberg, published in Proceedings magazine, the human brain stimulates regrowth to completely replace damaged cells. The researchers took brain tissue samples of people who had died after strokes and analyzed them for proteins associated with new and dividing brain cells. .... | |

This week, Sudan has sent in a high-powered team to negotiate with the Government about recruiting Kenyan teachers. It joins the ranks of Rwanda and Seychelles, which have entered into formal deals to get a supply of teachers. At the informal level, Kenyan teachers work in many southern African countries, notably Namibia, Botswana and Swaziland. The neighbouring countries have also been seeking Kenya's assistance on curriculum development and administration of examinations. The Commission for Higher Education was instrumental in helping Uganda and Tanzania set up their own regulators. For now, however, the focus is on exporting teachers to neighbouring countries.... | |

| | | Study: Pesticide harms human brain development | | Posted Saturday, July 08, 2006 5:08:11 PM by Blog57 Team | | LOS ANGELES (AP) - Babies of California farmworkers who were exposed to the insecticide DDT have neurological effects that include mental and physical impairment, according to a study published Wednesday. The study by scientists at the University of California, Berkeley measured levels of various pesticides in 360 pregnant women who recently emigrated from Mexico to the Salinas Valley and tested the mental and motor skills of their U.S.-born infants and toddlers. The mental tests measure the children's ability to learn and think, including memory and problem-solving skills. For every tenfold rise in DDT exposure, the children's scores on mental tests dropped 2 to 3 points. Their motor skills were also reduced. In the most severe cases, the highest DDT doses were associated with a 7- to 10-point drop in the mental scores of 2-year-old children compared with those who were not exposed.... | |
