    (Nanowerk Spotlight – by J.D. Beard) Traditional techniques in cell biology involve chemical or pharmaceutical treatments of entire cells; however, in many cases it would be advantageous to target a single organelle or other structure within a cell without damaging overall cell structure. If scientists could inject a drug into a chosen organelle within the cell, or even destroy, extract or isolate the whole organelle without significantly harming the cell itself, new insight could be gained into the inner workings of the cell. In recent years, techniques have been developed which allow the manipulation of the individual nanoscale structures within biological cells.

    The complete article can be viewed at the Nanowerk site.  They have some really good nano technology articles.  Most of them boggle my mind & challenge it too.  If I could do it over, I think this is an area I would enjoy working within.

    This is the third time I have written this article. I am using a new IE8 add-on called Zemanta. Somehow it is not cooperatng with the style of adding and editing data that I am used to. I cut & paste a lot and with WordPress the data just totally disappears..Grouse, Grouse.

    It has been raining since 0500 hrs this morning. Sometimes heavy and somtimes just a mist. It is also pleasantly warm outside at about 65 °. This condition shows no signs of changing untill after the cold front passes sometime tonight and then the temperatures will drop.  The forcast says 50 ° for the high tomorrow with some higher type winds from the West.  This is good for the leave raking scenerio.

    We have done 5 cart loads of mulched leaves so far – a cart load is about 36-40 cubic feet of densely packed chopped leaves – and this is about 20-25% of a seasons normal drop.  This means 15 more cart loads to go.

    In a way it is somewhat enjoyable but in others it is a real pain.  As the years go by it is more of a pain.  As I watch out the window towards the lake the wind is whipping the smaller tree branches around whilly nilly.  Some tenacious leaves refuse to fall and yield to the inevitable: Sort of like me.  I should go out and take a picture but I am too lazy to do it, so I’ll just continue to write and pretend it is not 1715 hours and the twlight hours are just around the corner.
