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!

Simple Treatment Prevents Premature Births
Treating high-risk pregnant women with the hormone progesterone cut their rate of early delivery by 45 % and helped lower the risk of breathing complications in their babies.

Babies Are Born Early Near Busy Road Intersections
Babies are born earlier when their mothers live near a concentration of freeways and main roads, reports a study of 970 mothers and their newborn babies in Logan City, a town south of Brisbane, Australia.

New Gene Influencing Risk For Developing Epilepsy
Vanderbilt University researchers have identified a new gene that can influence a person's risk for developing epilepsy.

Gene Linked To Autism's Social Dysfunction
With the help of two sets of brothers with autism, Johns Hopkins scientists have identified a gene associated with autism that appears to be linked very specifically to the severity of social interaction deficits.

Study Reveals How Eye Is Formed
Scientists at King’s College London have discovered specific cells responsible for ensuring that different parts of the eye come together during development.

WHO Child Growth Charts

Senior research fellow and Associate Professor Adrian Barnett from Queensland University of Technology's (QUT) Institute of Health and Biomedical Innovation (IHBI) published the study in the online journal Environmental Health, showing that the more freeways and highways around a pregnant woman's home, the higher the likelihood of her baby being born prematurely.

"The most striking result was the reduction in gestation time of 4.4 per cent or almost two weeks associated with an increase in freeways

within 400 metres of the women's home," said Professor Barnett, whose earlier study found a strong association between increased air pollution and small fetus size.

"Although the increased risks are relatively small, the public health implications are large because everyone living in an urban area gets exposed to air pollution. Pre-term and low-birth weight babies stay in hospital longer after birth, have an increased risk of death and are more likely to develop disabilities."

Professor Barnett said although air pollution levels in south-east Queensland were low compared with industrial cities, people's exposure to the chemical toxins in vehicle emissions was relatively high because of our outdoor lifestyle and open houses.

The study counted the number of roads around the mother's homes up to a 500 metre radius.

"We examined the distance between the home and busy roads to find the distance at which most of the negative effects on birth outcomes occurred because this has implications for local governments planning expansions or new roads," he said.

Most of the effects were within a 200-metre radius, but negative health effects were present up to 400 metres.

Professor Barnett said the study had also taken into account the effects of smoking levels and the socio-economic status of the mothers.

The effects of noise pollution were considered to be a possible contributing factor, but Professor Barnett said it was difficult to separate the effects of air and noise pollution.

"Vehicles braking and starting means that road junctions have some of the highest levels of noise and air pollution," he said.

"Disturbed sleep during pregnancy may cause extra stress and be a risk factor for adverse birth outcomes.

"This study points to the fact that pregnant women should reduce their exposure to traffic. A reduction in traffic emissions through improved vehicles or increased public transport use would have immediate health benefits by giving children a better start to life."
