African-Americans at Increased Risk for Earlier Preterm Births Multiple Pre-Term Births Also More Likely
Using data from over 700,000 births in Missouri from 1989 to 1997, researchers found that African American mothers were 3 times more likely than Caucasian mothers to deliver prematurely at 20-34 weeks and almost 4 times more likely to deliver extremely prematurely at 20-28 weeks. (Full term births occur at 37-41 weeks gestation.) The results of the study are published in the February issue of the American Journal of Obstetrics & Gynecology.
African American mothers were also more than 5 times more likely to have repeating premature births than Caucasian mothers. Although all mothers who had initially delivered a premature infant at 20-34 weeks of gestation were more likely to do so again, the rate for Caucasian women was 9.2% and the rate for African American women was 21.5%.
Writing in the article, Louis J. Muglia, MD PhD, from the Center for Preterm Birth Research at Washington University School of Medicine, states, “We find that African-American women experience preterm birth not only at increased rates as compared to Caucasian women, but also at earlier gestations and with increased repetition… [We] further analyze the pattern of recurrent preterm birth stratified by race and find that the tendency to repeat preterm birth during the same week occurs for both Caucasians and African Americans, but the median age for preterm birth is shifted two weeks earlier in African Americans.
These findings together highlight the importance of race, particularly after correction for other risk factors, and suggest a probable genetic component that may underlie the public health problem presented by the racial disparity in preterm birth.”

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Mapping the interaction of a single atom with a single photon may inform design of quantum devices
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
