If you drink alcohol your ability to drive a motor vehicle is definitely negatively affected.  What about other drugs though?  A US attorney Matt Abel claims that "stoned" drivers were much safer than those who did not use marijuana.  The attorney is leading a petition calling for the decriminalization for people 21 and over. He cites research studies that show marijuana affected drivers moved more slowly.  Their body actions were slow.  This, he claims makes them safer drivers.  If a driver has another car speeding toward him from the rear, he would prefer that the other driver had extremely fast reflexes, not slow ones. Some research has found that some marijuana smokers performed as well as they did without the substance, but there was no improvement.  Most studies, however, show clear negative affects on driving from marijuana intoxication.  In Australia marijuana smokers were most likely to be at fault in motor vehicle accidents.  Like alcohol the more marijuana consum

It was thought that monkeys and chimpanzees were unable to use language as humans do because they do not have the required language centers in their brains.  Tests on baboons turned this theory on its head.  Monkeys learned the rules of words, for example consonants and vowels, so they could recognize real words in a bundle of made up nonsense. Humans must first build up words from letters before they get meaning.  We need to construct words as if they were tables and chairs, from the legs up. Baboons were tested by encouraging them to "play" with computers.  When they selected a real word they got wheat as a reward.  Each computer had a cross and a circle so the baboons could show words and non-words by pressing either symbol.  The words were only four uppercase letters long, but each baboon did up to 60,000 tests and they were 75 per cent correct.  The best baboon learned 308 words http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http:

It seems the level of intelligence is determined by a few genes.  This must surely be too simplistic, particularly because specialists cannot agree on what intelligence is.  How do you compare memorizing general knowledge to the skill of knitting a fine jumper?  There are people who know just about everything about Australian rugby league, but this is their only area of expertise. Finding will be made easier, apparently, by questioning the crowd rather that by brain scans, etc.  It is believed that the sought after genes affect brain size.  Considering that Neanderthals had larger brains than modern man, this seems to be the wrong hypothesis to start with. While "the team" is sure they will find the genes they do admit that culture, education, health and upbringing can affect intelligence.  How are they going to filter these things out?  Obviously they can't.  Twenty one thousand subjects were catalogued and brain imaging was used.  Strangely, when the team was r
