New insight into mechanism of aging

Researchers believe they’ve discovered how a rare genetic defect causes premature aging. The process they uncovered may play a role in the normal aging process as well. more  

Hutchinson-Gilford progeria syndrome

Hutchinson-Gilford progeria syndrome is a genetic condition characterized by the dramatic, rapid appearance of aging beginning in childhood. Affected children typically look normal at birth and in early infancy, but then grow more slowly than other children and develop a characteristic facial appearance, hair loss (alopecia), aged-looking skin, and severe hardening of the arteries (atherosclerosis). more

Genetically altered mice see a more colorful world

By giving mice the gene that allows people to see red hues, scientists have created rodents that can see a wider range of colors. The study offers clues to the evolution of color vision and suggests that the brains of mammals can quickly adapt to new sensory information. more  

Assisted reproductive technologies don’t affect genetic code

Technologies to help women become pregnant have been growing in popularity ever since the birth in 1978 of the first successful "test-tube baby," which was conceived by in vitro fertilization. Many people, however, still worry that assisted reproduction technologies may carry health risks. A new study in mice can partly set their minds at ease. It found that the technologies had no detectable effects on the genetic code. more

What is infertility?  

Infertility is the term health care providers use for women who are unable to get pregnant, and for men who are unable to impregnate a woman, after at least one year of trying. more

Do I have premature ovarian failure (POF)?  

This 24-page booklet is part of the NICHD's research portfolio in women's health. Premature ovarian failure (POF), also known as ovarian insufficiency, describes a loss of ovarian function before normal menopause. This booklet for women and their families explains POF, its possible causes, its symptoms, and its treatments and explains some NICHD research on the condition. more

Chronic family stress linked to illness in children

A new study found that chronic family stress was associated with increased illnesses in a group of socioeconomically and racially diverse school-aged children. more
