In vitro fertilization has caused a few problems, but it has brought new hope to couples who were formerly unable to conceive. One controversial side effect is that embryos with genetic diseases can be culled. This brings up a brand new moral choice for our time.
Babies that are born in the winter are bigger and do better. They may be smarter as well, since at the age of 7, children born in the winter months have larger heads. The season when you're born can also determine whether or not you turn out to be an optimist or a pessimist.
With the current epidemic of obesity and Type II diabetes among both children and adults, researchers are trying to determine if what our mothers ate influences our future health. Their conclusion: it does?a lot.
Dr. Donald Novak says, "There are many people around the world who don't have enough protein in their diets, and malnutrition...
Women are more likely to give birth to a boy if they're inan environment that will allow them to live to an old age,because healthy women have more testosterone, which promotesthe survival of the male fetus. But women who only thinkthey'll live a long time also have more boys.
This correlates with an earlier story showing that when...
Scientists think that if women take choline during their pregnancies, they?ll "super-charge" their children's brains for life. If they eat chocolate daily, they'll have a happier baby. And if they have a toddler who's a finicky eater, it's because of the way he was fed as an infant.
Babies born to pregnant rats that were given the...
Scientists may have come up with the answer to the question every parent wants answered: why is their baby crying? You've fed him, changed him, taken his temperature?nothing works. If only he could tell you what's wrong.
Now a device has been invented that can translate a baby's cries. A microchip monitors volume, pattern and interval...
Scientists are worried that in fertility clinics using in-vitro (test tube) fertilizations, parents will be able to select embryos for IQ or personality traits. Now embryos are selected according to which ones are healthiest and free of genetic disease. Future genetic testing could allow them to be selected for above average intelligence, good...
Prospective parents can now "feel" a baby in the womb with the aid of a computer system that converts ultrasound images into a tactile virtual picture. A 3D ultrasound image of the baby is generated by layering successive 2D pictures on top of one another. The computer then traces the features of the fetus and allows the 3D shapes to be felt...
Babies have mastered the art of learning in their sleep. By the time they?re a year old they can recognize many sounds and even simple words. Marie Cheour at the University of Turku in Finland thinks they progress this fast because they learn language while they sleep as well as when they?re awake.
