[Temporal factors in motor vehicle crash deaths Injury Prevention 2005; 11: 18-23] / [Heat related deaths in young children in parked cars: an analysis of 171 fatalities in the United States, 1995-2002 Injury Prevention 2005; 11: 33-37]
More than 100 people die on US roads every day, but there is definitely a seasonal trend, with the highest average death toll on July 4, Independence Day, reveals research in Injury Prevention. Researchers from the Insurance Institute for Highway Safety analysed data from the national Fatality Analysis Reporting System for the years 1986 to 2002 to see if they could identify any trends in the timing and severity of car crashes.
They compared days with relatively high numbers of car crash deaths with the two days exactly one week before and week afterwards, in a bid to rule out any anomalies in the figures. The analysis showed that on average 117 people die on US roads every day, but the death toll ranged from 45 to 252 deaths on any one day. There were more road deaths during summer and autumn than during winter and spring, largely because of the increased volume of traffic on the roads, suggest the authors. There were more deaths in August than any other month, and more deaths from June to November than from December to May. The fewest deaths occurred in January and February, but far fewer journeys were made during these months.

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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
