Defining a national standard for dynamic pressure waves

In recent years, the physical damage done by pressure waves – such as traumatic brain injuries from explosives sustained by military personnel in the Middle East – has become an increasingly urgent public concern.

Dynamic calibration of pressure sensors using shock tube

Scientists at NPL's Dynamic Pressure Sensor Facility have published a paper, Towards a shock tube method for the dynamic calibration of pressure sensors, in Philosophical Transactions of the Royal Society A.

Formula calculates thickness of bombproof concrete

A new type of steel-reinforced concrete protects buildings better from bomb attacks. Researchers have developed a formula to quickly calculate the concrete's required thickness. The material will be used in the One World ...

Earth's core reveals an inner weakness

(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy and diffraction ...

Supersense: It's a snap for crocs

Previously misunderstood multi-sensory organs in the skin of crocodylians are sensitive to touch, heat, cold, and the chemicals in their environment, finds research in BioMed Central's open access journal EvoDevo. These sensors ...

Earth's iron core is surprisingly weak, researchers say

The massive ball of iron sitting at the center of Earth is not quite as "rock-solid" as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet's ...
