Designer Babies: Creating The Perfect Child

From CNN:

LONDON, England (CNN) -- Bring your partner, grab a seat, pick up your baby catalog and start choosing.

Will you go for the brown hair or blond? Would you prefer tall or short? Funny or clever? Girl or boy? And do you want them to be a muscle-bound sports hero? Or a slender and intelligent book worm?

When you're done selecting, head to the counter and it's time to start creating your new child.

Does this sound like a scary thought?

With rapid advances in scientific knowledge of the human genome and our increasing ability to modify and change genes, this scenario of "designing" your baby could well be possible in the near future.

Techniques of genetic screening are already being used -- whereby embryos can be selected by sex and checked for certain disease-bearing genes. This can lead to either the termination of a pregnancy, or if analyzed at a pre-implantation stage when using In Vitro Fertilization (IVF), can enable the pregnancy to be created using only non-disease bearing genes.

From Live Science:

Babies as young as 5 months can distinguish an upbeat tune, such as "Ode to Joy" from Beethoven's Ninth Symphony, from a lineup of gloomy tunes.

Researchers displayed an emotionally-neutral face for the baby while sad music played. When the baby looked away from the face, the music stopped and a new sad song would start. When the happier "Ode to Joy" played, the babies stared at the face three to four seconds longer, suggesting they were interested in the shift.

By 9 months old, babies can do the opposite, picking out the sorrowful sound of Beethoven's Seventh Symphony from a pack of happy pieces.

The finding is another example of how babies make sense of the world long before they can talk, said Brigham Young University psychology professor and study author Ross Flom.
