365 Daily Lessons - Day 4 Science "Cloning"



Well, hello Dolly!

Science fiction became reality in 1997 when the first clone was created, a Finnish Dorset sheep named Dolly.  Scientists at the Roslin Institute in Scotland created Dolly by a process called nuclear transfer.  *grab your science hat - here we go* This process is made by taking the genetic material from an adult donor - in this case a 6 year old ewe - and transferring it into an unfertilized egg whose genetic material had been removed.  The researchers shocked the egg and it began dividing into an embryo.

Whew!

The ewe whose genetic material was used to create Dolly was, for all intents and purposes, her mother.  And you would think that a clone would be an exact replica but Dolly had many differences than her mother.  One way that's noted in this book is that specific chromosomes developed differently.  By the term "many" being used for their differences I believe I'll have to research on my own what the rest were because they aren't noted on this page.

Dear Dolly was diagnosed with lung cancer and crippling arthritis and was laid to rest in 2004 when she was six.  Considering the life expectancy of a Finn Dorset sheep is about 12 years and that she was created from a ewe that was 6, that time frame seems right.  Dolly was the mother of six.  No science was used in those creations :->

So, would you like to be cloned?

Miss Poodle Perm, That's Me!

Jill of Scary Mommy is doing a linky post about school pictures. You know the ones, possibly you didn't smile a sweet smile, just the smirk of panic. Or you didn't know it was picture day because you had been out sick for a week and you show up in your most comfortable shirt and bed-head. (Yep. That happened to me. The smile was good though!)

Well, my scanner isn't working or else I would post a particular picture from Freshman year. Since I don't have a visual, here's the story:

I remember my first day of High School. Actually what I remember is the picture taken of me leaving for my first day of High School. I'm wearing a brave smile, but the hair, the hair, my hair style was a nightmare.
My two best friends and I were going to be attending a High School out of our district. That was stressful enough. To add to this new-ness we wanted new looks as well. K. was going to sport the Argyle and Alligator shirt look. W. was going for 'All Monogrammed, Al…

How to Find the Safest Gear for your Baby

Nothing compares to the joys of being a parent. Having a newborn in the family brings couples closer and makes the entire household more cheerful and interesting.

More than anything else, it also requires exerting a lot of effort to make sure that your baby is always safe and free from potential hazards. To further help you in this endeavor, here are some useful tips for finding the safest gear for your baby as you go through various baby product guides:

Opt for a non-toxic gear. The first thing you need to check is the composition of the safety gear. What is the material made from? Is it non-toxic? Be sure that it is because babies have a strong tendency to put everything they see or touch in their mouths. It goes without saying that a safety gear that is made from toxic materials could poison your baby, in the long run, so be very careful about the safety gears you purchase.
