We met people from all around the world, worked with the offspring of establishment icons (Marlboroughs, Nelsons etc.), played Peter Gabriel’s “So” until the player died and had our young eyes opened to a lifestyle not seen in the former industrial towns and cities of the Midlands and elsewhere. London was also a cleaner, less crowded, more affordable and liveable place then. At the end of the 80s I switched my “Sweeney” ambitions for “Rumpole” ones, travelled and eventually emigrated to Canada a decade later..
I have a 9 year old daughter that was paddled by the Middle Valley Elementary School principal when she was 5 in Hixson, Tennessee. Did I mention that my daughter is disabled with an IEP from the school board? My daughter has a developmental speech impediment at the time was so severe that she was difficult to understand. Also, my ex wife was taking our daughter to a neurologist for seizures at the time of the incident.

A new study published Monday in the Proceedings of the National Academy of Sciences confirms that’s no fluke and suggests how that bias may have arisen. In fact, one had a whopping 18 per cent more of one particular amino acid.Glavin and Dworkin suggested that such meteorites, asteroids, comets and their fragments may have delivered extra left handed amino acids to the earth before life began and “biased” the Earth’s inventory of organic compounds, encouraging living things to build themselves using the more readily available left handed version.The study used a different analysis technique than had been used by other studies, independently backing up the results of those previous studies.The researchers also noticed a pattern only meteorites that were extensively altered by water while still attached to their parent asteroid have the large excess in left handed amino acids.”Therefore, water played a very important role in the bias of left over right handed amino acids in meteorites,” Glavin said in an email.Posted: 2009/03/17 at 12:19 PMThere is no credible explanation for biological homochirality: chiral L protein amino acids and chiral D sugars.
