UNC study pinpoints gene crucial for female embryo survival
Gene keeps paternal X chromosome inactive

When One Gene Has Two Roles, Its Second Function May Be Missed
Scientists found that the same master gene that controls development of all of the body's blood cells is later activated in other cells of the embryo to form the genitourinary tract.

Most clones doomed from the start, according to Temple University embryologist
Until scientists can improve the early development of cloned embryos, cloning will remain marginally successful

Mouse study identifies protective mechanism against alcohol-induced embryo toxicity
Researchers have identified a mechanism by which the eight amino acid peptide NAP, an active fragment of a neuroprotective brain protein, protects against alcohol-induced embryo toxicity and growth retardation in mice.

Researchers Discover Initial Steps In Development Of Taste
Of the five senses, taste is one of the least understood, but now researchers have come one step closer to understanding how the sense of taste develops.

The molecular basis of transdifferentiation
In the present review the authors discussed the identification of selector, or master switch, genes as well as examples of transdifferentiation...

Researchers Discover How A Key Dietary Vitamin Is Absorbed
Researchers at the Albert Einstein College of Medicine of Yeshiva University have found the mechanism by which the B vitamin folate--a crucially important nutrient--is absorbed by the intestinal tract.

Why Embryos Need A Good Diet
A thick-coated vole and a man with cardiovascular disease have something in common: both are doing what their mothers told them.

Multiple-birth Babies, Boys Have Higher Risk Of Defects
Twins, triplets and other multiples have a nearly 50 percent greater chance of being born with birth defects, and boys tend to be more at risk than girls, according to two population-based studies

Veterinary Researchers Seek Secret To Reversing Birth Defects
Fetal development is a highly choreographed process. But all too often it is disrupted when a mother is exposed to a teratogen an agent known to cause a variety of birth defects.

Polarity and intracellular compartmentalization of Drosophila neurons
Proper neuronal function depends on forming three primary subcellular compartments: axons, dendrites, and -generic drug-.

Fetus Heart Races When Mom Reads Poetry; New Findings Reveal Fetuses Recognize Mother's Voice In-utero
New research findings on the ability of a fetus to recognize its mother's voice and even distinguish it from other female voices confirms what scientists have speculated about for more than 20 years - that experiences in the womb help shape newborn prefer

Lola regulates Drosophila olfactory projection neuron identity and targeting specificity
Longitudinals lacking (lola) is required for wiring of axons and dendrites of most PN classes, and suggest a need for its molecular diversity.

Calcineurin Helps Newborns Breathe Easy
It is only very late in pregnancy that the lungs of the fetus complete their development so that the fetus will be able to breathe air when it is born.

Nerve Navigation Findings Prompt New Direction For Spinal Cord Research
A piece of the puzzle of how nerves find their way across the midline of the brain and spinal cord in a developing embryo has been found by Medical College of Georgia researchers.

Possible New Cell Type Found In Developing Inner Ear
The answer to how the complex, cavernous inner ear forms from a mostly homogenous group of cells may be that it doesn't

Ozone Levels May Raise Risk Of Underweight Births: Common Pollutants Linked To Fetal Growth Retardation
Babies born to women exposed to high ozone levels during pregnancy are at heightened risk for being significantly underweight, according to researchers ...

Scientists Discover Key Ingredient In Sexual Reproduction
People have wondered exactly how sperm-egg contact initiates development... the answer begins with the build-up of nitric oxide gas inside the sperm, says biologist.

The Embryo and Its Future
The preimplantation mammalian embryo from different species appears sensitive to the environment in which it develops, either in vitro or in vivo, for example, in response to culture conditions or maternal diet.

Scientists Discover New Gene Essential For The Development
Biologists at the University of California, San Diego and the Johns Hopkins University have discovered a gene that plays a key role in initiating changes in the brain in response to sensory experience
