Cheep News Struggled to find something to post that would interest you guys, so I settled for this. Are you guys right or left handed? Wanna know why?... __________________________________________________________________________________________________________________________ A preference for the left or the right hand might be traced back to that asymmetry. "These results fundamentally change our understanding of the cause of hemispheric asymmetries," conclude the authors. The team report about their study in the journal eLife. Preference in the womb To date, it had been assumed that differences in gene activity of the right and left hemisphere might be responsible for a person's handedness. A preference for moving the left or right hand develops in the womb from the eighth week of pregnancy, according to ultrasound scans carried out in the 1980s. From the 13th week of pregnancy, unborn children prefer to suck either their right or their left thumb. Arm and hand movements are initiated via the motor cortex in the brain. It sends a corresponding signal to the spinal cord, which in turn translates the command into a motion. The motor cortex, however, is not connected to the spinal cord from the beginning. Even before the connection forms, precursors of handedness become apparent. This is why the researchers have assumed that the cause of right respective left preference must be rooted in the spinal cord rather than in the brain. The influence of environmental factors The researchers analysed the gene expression in the spinal cord during the eighth to twelfth week of pregnancy and detected marked right-left differences in the eighth week -- in precisely those spinal cord segments that control the movements of arms and legs. Another study had shown that unborn children carry out asymmetric hand movements just as early as that. The researchers, moreover, traced the cause of asymmetric gene activity. Epigenetic factors appear to be at the root of it, reflecting environmental influences. Those influences might, for example, lead to enzymes bonding methyl groups to the DNA, which in turn would affect and minimise the reading of genes. As this occurs to a different extent in the left and the right spinal cord, there is a difference to the activity of genes on both sides. ___________________________________________________________________________________________________________________ Post if you are right or left handed.

So, people have constantly told me I have an excellent taste in music, so thought I'd share some of what has been playing over and over and over and over on my playlist: http://www.youtube.com/watch?v=q_Gh8TWpQE8 Scroobius Pip - Introdiction http://www.youtube.com/watch?v=QjAy95aJKSs Dan le Sac vs Scroobius Pup - Back From Hell http://www.youtube.com/watch?v=WQ-sKXuauTY M83 - We Own The Sky (this video should be seen in HD and Full screen) http://www.youtube.com/watch?v=l0FU64i7aoQ SBTRKT - Hold on http://www.youtube.com/watch?v=DsYwtkNM3i4 Glasser - Apply http://www.youtube.com/watch?v=tZtEtiJxQxM Chemical Brothers - Hanna's theme (vocal version)
