The Assisted Reproduction Unit at the Quir?n Hospital in Donostia-San Sebasti?n has managed, for the first time in the Basque Country, to successfully carry out an embryonic sex selection in a woman who is a carrier of the disease Retinosis Pigmentaria, linked with the X chromosome — in order to avoid giving birth to a male child.
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial “progenitor” stem cells persist in the aging brain.
Like movie makers who dazzle audiences with virtual imagery created with supercomputers, scientists rely on massive computational power to build digital worlds that simulate major earthquakes to help design better buildings, predict the path of plumes from smokestacks, and even recreate the birth of stars.
Scientists have discovered the basis for a noninvasive test to diagnose common infections in pregnant women that are a major cause of premature births and infant deaths. The University of Washington?s Michael G. Gravett and colleagues are reporting identification of protein biomarkers for these hard-to-diagnose infections of the amniotic fluid, which surrounds the fetus prior to birth.
The Assisted Reproduction Unit at the Quir?n Hospital in Donostia-San Sebasti?n has managed, for the first time in the Basque Country, to successfully carry out an embryonic sex selection in a woman who is a carrier of the disease Retinosis Pigmentaria, linked with the X chromosome ? in order to avoid, in case the patient were to give birth to a male child, the son suffering from blindness.
The IUD might be one of the best-kept birth control secrets for young women, according to researchers at the University of Rochester Medical Center.
The birth of a first child is usually an exciting and eagerly anticipated milestone in any committed relationship, yet research suggests it can also be the beginning of the end for many couples.
Science may be one step closer to understanding how a limb can be grown or a spinal cord can be repaired. Scientists at The Forsyth Institute have discovered that some cells have to die for regeneration to occur.
Researchers at the University of Leicester have identified for the first time a gene which causes a distressing eye condition. Their discovery, as reported in the journal Nature Genetics, is expected to lead to better treatments for the condition.
In the United States, the total fertility rate — the number of children a woman has in her lifetime — fell from seven or eight in 1800 to slightly more than two today, says J. David Hacker, assistant professor of history at Binghamton University. And with a five-year $667,237 grant from the National Institute of Child Health and Human Development, Hacker hopes to find out why.
