Preeclampsia, the development of high blood pressure and protein in the urine during pregnancy and its more severe complications such as eclampsia, can threaten the lives of both mother and child. While there is no therapy to prevent preeclampsia, a link to calcium deficiency has been suggested. In a study published in the March issue of the American Journal of Obstetrics and Gynecology, researchers across the globe, under the auspices of the World Health Organization (WHO), investigated whether a calcium supplement could reduce the complications and mortality from this condition.
Over 8300 women with low dietary calcium (<600 mg/day, about half of that recommended during pregnancy) were selected for the study. The subjects were randomly divided into two groups that had similar gestational ages, demographic characteristics, and normal blood pressures before treatment started. Half were given 1.5g of a calcium supplement per day and half received a placebo.
While the incidence of preeclampsia was not statistically different in the supplemented women, eclampsia, other severe complications and severe gestational hypertension were significantly lower. Overall, the "severe preeclamptic complications index" and the "severe maternal morbidity and mortality index," including all severe conditions, were also reduced with calcium.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
