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!

Defending the Genome
New research illustrates how the genome adapts to a transposon invasion that threatens fertility in the fruit fly. The same mechanism may exist in humans.

Multiple Sclerosis Not an Immune System Disease
Recent research argues that multiple sclerosis, long viewed as primarily an autoimmune disease, is more similar to hardening of the arteries.

Toddlers Rely On Others To Monitor Their Speech

New evidence shows that toddlers don't respond to their own voice in quite the same way as older children, according to a report published online on December 22 in Current Biology, a Cell Press publication.

The findings suggest that very young children must have some other strategy to control their speech production, the researchers say.

"As they play music, violinists will listen to the notes they produce to ensure they are in tune," explained Ewen MacDonald of the Technical University of Denmark. "If they aren't, they will adjust the position of their fingers to bring the notes back in tune. When we speak, we do something very similar. We subconsciously listen to vowel and consonant sounds in our speech to ensure we are producing them correctly. If the acoustics of our speech are slightly different from what we intended, then, like the violinists, we will adjust the way we speak to correct for these slight errors. In our study, we found that four-year-olds monitor their own speech in the same way as adults. Surprisingly, two-year-olds do not."

That's despite the fact that infants readily detect small deviations in the pronunciation of familiar words and babble in a manner consistent with their native language. By the time they turn two, American children have an average vocabulary of about 300 words and appear well on their way to acquiring the sound structure of their native language.

In the experiment, adults, four-year-olds, and two-year-olds said the word "bed" repeatedly while simultaneously hearing themselves say the word "bad." (To elicit those utterances from the young children and toddlers, the researchers developed a video game in which players help a robot cross a virtual playground by saying the robot's 'magic' word "bed.")

"If they repeat this several times, adults spontaneously compensate, changing the way they say the vowel," MacDonald said. "Instead of saying the word 'bed,' they say something more like the word 'bid.'"

Four-year-olds adjusted their speech, too, the researchers show. The two-year-olds, on the other hand, kept right on saying "bed."

MacDonald says the results suggest a need to reconsider assumptions about how children make use of auditory feedback. It may be that two-year-olds depend on their parents or other people to monitor their speech instead of relying on their own voice. MacDonald notes that caregivers often do repeat or reflect back to young children what they've heard them say.

While this study involved children with normal speech development, MacDonald says they'll be exploring potential applications for understanding or addressing delayed and abnormal early speech development.
