Britain is embarrassed as 38 terrorists break out of the Maze...
...arrival of the food van at Northern Ireland's Maze Prison on Sunday afternoon was routine enough. It was carrying the 4:30 meal (corned beef, pork, eggs, cheese, bread and tea) for the prison's inmates, many of them convicted terrorists of the Irish Republican Army. Passing through two security gates, the van pulled up in front of No. 7 H-block of the prison, site of dramatic I.R.A. hunger strikes two years ago. There the routine came to a violent stop. Prisoners armed with smuggled guns and homemade knives had already overpowered their guards; now they...
...plant at a rate of as much as 2.2 million bbl. a day, deoxygenated and heated from the Beaufort Sea's 28° to 40°. Then it will be pumped to another plant ten miles away, there to be heated to 80° and sent through a maze of 35 pipelines to injection wells in the oilfield...
...mental functioning in 21 rats whose brains had been damaged by removal of large sections of the frontal cortex. This section of the brain is involved in the learning of complex spatial relationships. Typically, rats sustaining such a severe injury would take 18 days or more to master a maze that required them to alternate right and left turns in the correct order to get a drink of water. "The rat has got to remember what he did the last time and then do the opposite," Stein explains. Normal rats can learn the task in just 2½ days...
...pinhead-size lump of tissue that had been taken from the frontal cortex of normal rat embryos. The researchers used fetal cells because they are rich in growth factors and adapt easily to a new environment. Result of the operation: the brain-damaged rats were able to learn the maze in just 8½ days. While this is still slower than normal, says Stein, "the transplant was clearly producing some degree of functional recovery." Stein later found that new connections had grown between the transplanted tissue and the rest of the brain...
