How to Extract DNA from Anything Living First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds. The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy Peas Pour your thin pea-cell soup through a strainer into another container (like a measuring cup). Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix. Let the mixture sit for 5-10 minutes. Pour the mixture into test tubes or other small glass containers, each about 1/3 full. Why am I adding detergent?
How to make gift bags from newspaper When I bought something at a store recently, the clerk handed me my purchase in a bag made from a newspaper. I liked it very much and had to make some more—thus today's DIY recycled newspaper project: gift bags made from the Wall Street Journal. You can vary the dimensions, of course, but here's what I used to create a bag that's 5" tall, 4.5" wide, and 3" deep. Stack two sheets of newspaper on top of each other. Cut out a rectangle that's 15.5" wide and 8.25" tall. Fold a flap 1.25" down from the top. Cut two pieces of cardstock or chipboard to 4.25" x 1", then glue them on the widest two panels just under the top fold. Put glue on the outside of the 0.5" tab and bring the left-most panel over to form the body of the bag, aligning the cut edge of the panel with the folded edge of the flap. Upend the bag so the 2" flap is now up. Put glue on both flaps and fold them inward to form the bottom of the bag.
Linux Directory Structure (File System Structure) Explained with Examples by Ramesh Natarajan on September 8, 2010 Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin?

Just like /bin, /sbin also contains binary executables.But, the linux commands located under this directory are used typically by system aministrator, for system maintenance purpose.For example: iptables, reboot, fdisk, ifconfig, swapon 4.

Kensho SCHOPENHAUER'S 38 STRATAGEMS, OR 38 WAYS TO WIN AN ARGUMENT Arthur Schopenhauer (1788-1860), was a brilliant German philosopher. These 38 Stratagems are excerpts from "The Art of Controversy", first translated into English and published in 1896. Carry your opponent's proposition beyond its natural limits; exaggerate it. The more general your opponent's statement becomes, the more objections you can find against it. The more restricted and narrow his or her propositions remain, the easier they are to defend by him or her. Use different meanings of your opponent's words to refute his or her argument.
