--Gene for left-handedness is found--
"" Plato and Aristotle puzzled over lefthanders, as did Charles Darwin. What determines "handedness"? Why are only 10 percent of us lefthanded, and why did the ratio seem to change over the last century? Are lefties somehow different - less healthy, more creative?""
The brain is set up in an asymmetrical way.
In right-handed people the left side of the brain usually controls speech and language, and the right side controls emotions.
However, in left-handed people the opposite is often true, and the researchers believe the LRRTM1 gene is responsible for this flip.
They also believe people with the LRRTM1 gene may have a raised risk of schizophrenia, a condition often linked to unusual balances of brain function.
--Scientists have discovered the first gene which appears to increase the odds of being left-handed.
The gene, LRRTM1, appears to play a key role in controlling which parts of the brain take control of specific functions, such as speech and emotion.
The study appears in the journal Molecular Psychiatry.

--US President Campaign Logo on Lefty '08--
--Barack Obama is a lefty. Our logo adapts his campaign logo and frames it around a left hand giving an OK sign. It’s time to get a lefty back into the White House.
