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.”

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.
As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...
Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.

In cooperation with the Center for Nano-Optics of Georgia State University in Atlanta (USA), scientists of the Laboratory for Attosecond Physics of the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser light.
Electrons hit by strong laser pulses change their location on ultrashort timescales, i.e. within a couple of attoseconds (1 as = 10 to the minus 18 sec). In...
