Study of development of cancer in seven Swedish counties establishes connection
A statistically determined correlation between radioactive fallout from the Chernobyl accident and an increase in the number of cases of cancer in the exposed areas in Sweden is reported in a study by scientists at Linköping University, Örebro University, and the County Council of Västernorrland County. It is the first study demonstrating such a correlation. It is being published in the scientific journal Journal of Epidemiology and Community Health. A rise in cancer cases related to the Chernobyl accident has previously been established in studies carried out in the former Soviet Union.
After the nuclear power accident at Chernobyl on April 26, 1986, some of the radioactive emissions were carried by the wind to Sweden. Heavy rain caused a relatively large amount, about 5 percent of the Cesium-137 released in the disaster, fell on Sweden, above all along the coastal area of Northern Sweden and northern central Sweden. The fallout in Sweden was unevenly distributed and, compared with the areas close to the nuclear power station at Chenobyl, considerably less. Knowledge of the possible consequences of radioactive fallout on health prompted a number of measures to be taken to reduce these consequences at the time of the Chernobyl accident.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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:...

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...
