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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
