### Posting latex equations in blogger.

When using the mathjax javascript code found at:

http://www.mathjax.org/docs/1.1/start.html#mathjax-cdn

One can post mathematical equations using latex as in the following example:

LaTeX Code:
When a \ne 0, there are two solutions to ax^2 + bx + c = 0 and they are
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.

RENDERED Equations:
When $$a \ne 0$$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

Great, so now I can make posts with simple matrix equations if necessary.

### Latest News from Chemical and Engineering News

To start the new year we look at the headlines related to nucleic acids in Chemical and Engineering News.
In the first week of the year two nucleic acid notes have been written in C&EN. One concerns genetic engineering modifying DNA sequences by using Zinc-finger nuclease proteins, and the other also concerns genetic engineering but this time at the expression level by suggesting a protocol to program gene expression using so-called "RNA-devices".
