A new study published in BMC Public Health shows that breathing in second-hand smoke significantly increases the risk of developing heart problems in non-smokers. These findings have serious consequences for public health giving weight to calls for smoking to be banned in public places.
In 1995 cardiovascular diseases accounted for nearly 15 million deaths, approximately 30% of deaths worldwide. Smokers are becoming increasingly aware of the links between smoking and heart disease as warnings such as "smoking causes heart disease" are emblazoned across cigarette packaging across the world. The effects of second hand smoke or passive smoking is less clear because it is difficult to measure the exposure of non-smokers to cigarette smoke. Researchers at the University of Athens in Greece have carried out an extensive survey of approximately 2000 non-smoking patients. The patients were volunteers from two different groups, the first contained patients who had attended hospital suffering from a heart attack or acute angina that was not a result of a pre-existing condition. The second control group consisted of patients being treated as outpatients for routine examinations or minor surgical procedures who had no history of cardiovascular problems.
Both groups completed a questionnaire, which asked a variety of questions to identify factors that may put them at risk of developing heart problems. These factors included age, hypertension, high cholesterol, diabetes, a family history of heart disease, physical inactivity, obesity, poor education, depression and low income.

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:...
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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
