Team invents sensor that uses radio waves to detect subtle changes in pressure
Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries.
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 ...
New research shows how water is transferred into our planet's interior
The Earth's interior could contain more than three times the amount of water in all our oceans combined, existing within the structures of silicate materials that are stable at the prevailing conditions deep ...
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 ...
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 ...
A microphone that listens with light
A sensor developed in Norway gives microphones hyper-acute hearing and a sense of direction.
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 ...
Anatomy of a blast: Researchers develop sensor system to assess the effects of explosions on soldiers
(Phys.org) —Improvised explosive devices (IEDs) are becoming a global problem for the U.S. armed forces. To prevent injuries to soldiers and provide better care to those who are injured, the U.S. military ...
Incoming! Then outgoing! Waves generated by Russian meteor recorded crossing the US
(Phys.org) —A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States.
New study suggests Earth's lower mantle penetrated by metallic blobs
Sound bullets in water
Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by ...
High-pressure science gets super-sized
(Phys.org)—The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid.
Controlling air flow over wings during supersonic flight
EU-funded researchers evaluated control techniques of air flow over aeroplane wings during supersonic flight. The optimal wing design developed should lead to important reductions in noise, emissions and ...
