Brain anatomy of dyslexia not the same in men, women, boys or girls
Diagnosis and intervention could be impacted by new findings that the disorder may have a different brain-based manifestation based on sex.

Early infant growth rate linked to gut microbiota
Composition of gut microbiota—the body's microbial ecosystem—in a new-born baby's gut has been linked to the rate of growth in an infant and the likelihood of obesity.

Dad's genome ready at fertilization, mom's need to catch up
Researchers have discovered that while the genes provided by the father arrive at fertilization pre-programmed to the state needed by the embryo, genes provided by the mother are in a different state and must be reprogrammed to match. The findings have important implications for both developmental biology and cancer biology.

Gene mutation causes Sturge-Weber syndrome—port-wine birthmarks
Researchers pinpoint genetic cause of rare disease—Sturge-Weber syndrome (SWS) and port-wine stain birthmarks. SWS is a rare disorder affecting approximately one in 20,000 births, while port-wine birthmarks affect approximately one million individuals in the United States.

2 Genes combine to cause rare cerebellar ataxia and reproductive failure
Mutations in genes that regulate cellular metabolism are found in families with a lack of muscle coordination and dementia, as well we reproductive failure.

One big European family!
From Ireland to the Balkans, Europeans are basically one big family, closely related to one another for the past thousand years, according to a new study of the DNA of people from across the continent.

Placental blood flow influences malaria during pregnancy
For the first time, mouse placental circultation was observed in live pregnancies showing how placental blood flow can influence malaria parasite behavior and infection.

Understanding the starlet sea anemone helps us understand ourselves
There's a new actor on the embryology stage: the starlet sea anemone, Nematostella vectensis. How it grows a tentacle helps explain how to construct a basic epithelial appendage, and may help us figure out how body parts are formed in general.

Hit by two hammers: Deficiencies in two genes halt formation of gut nervous system
Mutations in at least twelve genes are associated with the congenital defect Hirschprung Disease (HSCR), in which children are born lacking nerves that activate the large intestine. A new gene associated with HSCR shows how the migration of cells to form the gut nervous system are stalled when two candidate genes are low.

FDA warns pregnant women to not use certain migraine prevention medicines
Valproate products can lower IQ scores in children of mothers who used them during pregnancy.

Divide and define: How stem cells produce different kinds of cells
The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human.

'Bioelectric' Arteries Open Path to Heart Disease Treatment
A peculiar electrical property in arteries could lead to non-invasive heart disease treatments.

Saliva Can Clean Dirty Pacifiers and Reduce Allergy Risk
Parents use a variety of methods to clean a baby’s pacifier: rising it in tap water, boiling it, or putting it in their own mouth and sucking on it before giving it back to the baby.

New mechanism discovered in meiosis
Inactivated, but still active – how modification of an enzyme governs critical processes in sexual reproduction.

New brain research shows two parents may be better than one
A team of researchers at the University of Calgary's Hotchkiss Brain Institute (HBI) have discovered that adult brain cell production in mice might be determined, in part, by the early parental environment. The study suggests that dual parenting may be more beneficial than single parenting.

Turning human stem cells into brain cells
Medical researchers have manipulated human stem cells into producing types of brain cells known to play important roles in neurodevelopmental disorders such as epilepsy, schizophrenia and autism.
