Penn State simulation testing suggests that barriers, called underride guards, placed on the rear end of heavy trucks to prevent cars from sliding underneath and being crushed in rear-end collisions may be less effective if placed lower or higher than 16 inches (400 mm) from the ground.
The National Highway Transportation Safety Administration regulations set a maximum ground clearance of 22 inches (560 mm) and no minimum for underride guards on new trucks.
The Penn State simulation study also showed that underride guards that include diagonal struts increase impact resistance. When the struts are used, vehicle penetration under the truck was fairly small in the simulations.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
