Scientists Explain Why Computers Crash But We Don’t
The hierarchical organization of the transcriptional regulatory network ofbacterium E. Coli, left, shows a pyramidal structure compared to the Linuxcall graph, which has many more routines controlling few generic functions at the bottom. Nature and software engineers face similar design challenges in creating control systems. The Yale team compared the evolution of organisms and computer operating systems by analyzing the control networks in both a bacterium Escherichia coli and the Linux operating system. “It is a commonplace metaphor that the genome is the operating system of a living organism. Both E coli and the Linux networks are arranged in hierarchies, but with some notable differences in how they achieve operational efficiencies. In contrast, the Linux operating system is organized more like an inverted pyramid, with many different top-level routines controlling few generic functions at the bottom of the network.
What Happens to Your body if you stop smoking Right now?
Contributed byLiz Lewis I think one of the main reasons it’s so hard to quit smoking is because all the benefits of quitting and all the dangers of continuing seem very far away. Well, here’s a little timeline about some of the more immediate effects of quitting smoking and how that will affect your body RIGHT NOW. * In 20 minutes your blood pressure will drop back down to normal. * In 8 hours the carbon monoxide (a toxic gas) levels in your blood stream will drop by half, and oxygen levels will return to normal. * In 48 hours your chance of having a heart attack will have decreased. All nicotine will have left your body. So, you have more immediate things to look forward to if you quit now besides just freaking out about not being able to smoke.

A Beautiful Mess
I love using cloth napkins to dress up our dinner table, and through the years I've grown even more fond of their sustainability and cost effectiveness. Though, I'm not sure how cost effective it is if you keep buying more and more cloth napkins each year! This holiday season I thought it would be fun to look at how I could dress up the napkins I already own to give them an extra festive vibe. Ribbon Trimmed Napkin This look is so (no sew) simple! Supplies:-ribbon-heat bond in width of ribbon-cloth napkin (buy mine here)-iron-fabric scissors (not shown above) Step One: Trim pieces of your ribbon to be about 1.5 inches longer than the width of your napkins. Step Two: Fold down the edges of each ribbon segment about 1/4" and iron flat. Step Three: Iron the heat bond to the ribbon (pressing with hot iron for two seconds), then peel off the paper backing. Step Four: Iron the ribbon in place on your napkin front with the heat bond facing down. Pom-Pom Trimmed Napkin That's all there is to it!

Without further delay, lets get started with the process, of creating your super small high quality DVD Rip.
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?
