SI traceability for mercury vapour measurement in air
A new experiment, designed by NPL and the Joint Research Centre - Institute for Research Materials and Measurements (JRC-IRMM), has recently been completed and published in Analytical Chemistry.
Novel chip-based platform could simplify measurements of single molecules
Researchers at UC Santa Cruz have developed a new approach for studying single molecules and nanoparticles by combining electrical and optical measurements on an integrated chip-based platform. In a paper published July 9 ...
NASA sees Tropical Storm Karina losing its punch
Tropical Storm Karina continues to weaken in the Eastern Pacific over open waters, and NASA data shows there's not much punch left in the storm.
Sandia report draws lessons learned from 'perfect heists' for national security
In 2003, the unthinkable happened at Belgium's Antwerp Diamond Center. Thieves broke into its reputedly impenetrable vault and made off with hundreds of millions of dollars' worth of diamonds, gold, cash ...
Tropical Storm Karina: Status quo on infrared satellite imagery
Since Tropical Storm Karina weakened from hurricane status, and since then, NASA satellite data has shown that the storm has been pretty consistent with strength and thunderstorm development.
Pocket-size data recorder
A very compact device from Siemens is simplifying common sound and vibration measurements in industry. Until now, acceleration sensors and microphones have been attached to box-shaped devices connected to a computer. By contrast, ...
Air traffic growth set to outpace carbon reduction efforts
Carbon reduction efforts in the airline industry will be outweighed by growth in air-traffic, even if the most contentious mitigation measures are implemented, according to new research by the University of ...
Melt ponds shine in NASA laser altimeter flight images
Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal ...
Lifetime of gravity measurements heralds new beginning
Although ESA's GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn ...
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.
New launch date set for ISS delivery vessel
A robot ship will be launched from Kourou, French Guiana, after a five-day delay on July 29 to deliver provisions to the International Space Station, space transport firm Arianespace said Tuesday.
