• BBC has made a new webpage called “BLOOM=smart choices for the carbon conscience” for those who want to do their bit for the environment. It gives you practical suggestions to reduce CO2 emission, along with the costs and other information. I’m sure you can find a lot of helpful information in there. (thanks to Marco for sending me the link!)

I wrote a relatively long post in my Persian blog about Freiburg as part of Green movement between Persian bloggers. Freiburg is the Ecological and Solar capital of Germany. I thought here I can share one video and a few links for those who are interested:

• An interview about Freiburg history and how it became the Eco-friendly city
• More videos
• Solar region of Freiburg

The PCR Song
There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.
Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.
Just mix your template with a buffer and some primers,
Nucleotides and polymerases, too.
Denaturing, annealing, and extending.
Well it’s amazing what heating and cooling and heating will do.

PCR, when you need to detect mutations.
PCR, when you need to recombine.
PCR, when you need to find out who the daddy is.
PCR, when you need to solve a crime.
(repeat chorus)

• Kary Mullis, the one who developed PCR
• Polymerase Chain Reaction in Wikipedia

“There are two ways of spreading light: to be the candle or the mirror that reflects it.”

Edith Wharton

I first saw this quote in an Amnesty international commercial on YouTube. I was surfing in YouTube for the Amnesty international advertisement which you can watch here. I find it really well made,I thought I will share both with you.
