For Bio Glossary:
Gram staining (or Gram's method) is an empirical method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative) based on the chemical and physical properties of their cell walls.
Gram-positive bacteria are those that retain a crystal violet dye during the Gram stain process.
Gram-negative bacteria are those that do not retain crystal violet dye in the Gram staining protocol. Gram-positive bacteria will retain the dark blue dye after an alcohol wash. In a Gram stain test, a counterstain (commonly Safranin) is added after the crystal violet, coloring all Gram-negative bacteria a red or pink color.

Do you use GOOGLE.COM?
Obviously you do, 'cause Google's one of the biggest search engines ever!
Well it shows that if Google has a BLACK screen, it saves energy!
So STOP using Google, use
BLACKLE.COM!
Blackle is a product of Google, and it's got a black screen. Why? Simple. Your computer screen is originally black, so a white screen takes more energy and electricity to power up. Black screens however, save energy.
So SAVE THE EARTH! Use Blackle.Com. Spread the word! (:
Post this on your blogs and MSN nicks! :D
