Children of smokers have nicotine in their bodies, even if their parents smoke outdoors with the door closed. This is revealed in a study included in a doctoral dissertation by registered nurse and public health researcher AnnaKarin Johansson at Linköping University.
Going outdoors to smoke with the doors and windows closed is nevertheless clearly the best way to protect your child from passive smoking. The parents of 216 of 366 children aged 2-3 years used this method. But not even that provided full protection. A test for the cotine content (a metabolic product of nicotine) in the urine indicated that these children had twice as much nicotine in their body as children of non-smokers. In homes where both adults smoked indoors, children had fifteen times higher levels than children of non-smokers.
Another study, based on 1,600 responses to a questionnaire for parents with children aged 1-2 years, shows a correlation between passive smoking and respiratory ailments in children. Significant differences could be established regarding “wheezing” and long-term coughing.

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...
