Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

WHO Child Growth Charts


High-quality friendships in kindergarten may mean that boys will have fewer behavior problems and better social skills in first and third grades, said Nancy McElwain, a University of Illinois associate professor of human development and co-author of a study published in a recent issue of Infant and Child Development.

"The findings for girls were different," said Jennifer Engle, lead author of the study. "Overall, teachers reported that girls in the first and third grade had good social skills, regardless of the quality of their kindergarten friendships. Boys, on the other hand, clearly benefited from the good start that early high-quality friendships provide."

Engle said the study was unique in comparing how the presence and quality of children's kindergarten friendships are related to their behavior problems and social skills in kindergarten, first, and third grades.

She noted that friendship quality was important for both boys and girls in kindergarten. Kindergarten kids with high-quality friendships tended to have fewer behavior problems and better social skills than those whose friendships were of low or moderate quality. In contrast, kids who had low-quality kindergarten friendships had more behavior problems during kindergarten.

The differences in friendship quality for boys versus girls didn't show up until the children were older, she said.

"Boys who had no friends in kindergarten had more behavior problems, but not until they had reached first and third grades," she said.

The researchers examined data from 567 children who had participated in the Eunice Kennedy Shriver National Institute of Child Health & Human Development Study of Early Child Care and Youth Development.

Mothers in the study reported on whether their kindergarten child had at least one friend and on the quality of their child's friendships. Researchers then compared the progress of children with no friends, low-quality friendships, average-quality friendships, and high-quality friendships. Teachers provided feedback on children's behavior problems in kindergarten and first and third grades.

"As we expected, high-quality kindergarten friendships that featured cooperation and sharing, taking turns, low levels of hostility, and little destructive conflict, gave children—especially boys—practice in positive interaction, which they demonstrated in grades 1 and 3," Engle said.

How can you help your child learn to be a good friend? McElwain stressed that peers become important as children enter kindergarten. Parents should make an effort to help children, especially boys, make friends at this age through play dates and other social activities, she said.

Children also will likely relate to friends in more positive ways if they have experiences in their family that model positive expectations, caring, and respect.

When children learn to expect that people will respond positively to them, they will be responsive and friendly to others, she noted.

"Those children will be able to handle their emotions better when the going gets rough, and they'll learn how to work through conflicts. Conflict isn't necessarily good or bad; it's a matter of how kids approach disagreements with their friends or parents," she said.

McElwain offered reassurance to parents of friendless kindergartners. "Almost all of those children had made a friend by the time they reached third grade."
