Tomographic measurement of dielectric tensors
A research team reported the direct measurement of dielectric tensors of anisotropic structures including the spatial variations of principal refractive indices and directors. The group also demonstrated quantitative tomographic measurements of vario.....»»
Machvision takes rosy outlook on 2022 operations
Machine vision-based inspection and measurement equipment maker Machvision believes that demand for PCB, HDI (high-density interconnect), and IC substrate products has turned strong, and that electric vehicles, 5G, and high-performance computing are.....»»
Research team achieves breakthroughs in precision measurement by "scrambling" laser light
In most circumstances, disordered working conditions prevent us from performing accurate work. But in a reversal of this common wisdom, a team of researchers from the University of Adelaide and the University of St Andrews, Scotland has achieved rece.....»»
Studying clouds can provide deeper insight into climate change
An international team of scientists conducted CALISHTO, a large-scale air measurement campaign in Greece last fall, with the goal of surveying, counting and characterizing the tiny particles and their impact on cloud formation. The goal is to incorpo.....»»
Protons Are Probably Actually Smaller Than Long Thought
An anonymous reader shares a report from the University of Bonn in North Rhine-Westphalia, Germany: A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surpris.....»»
Evidence found for existence of two forms of liquid water
Yoshiharu Suzuki, a researcher with the Research Center for Advanced Measurement and Characterization, National Institute for Materials Science in Japan, has found evidence for the existence of two forms of liquid water. In his paper published in Pro.....»»
Here’s how and why you should set up Cardio Fitness on Apple Watch and iPhone
One of the valuable, and lesser-known health features on Apple Watch is Cardio Fitness. The measurement is based on your VO2 max which Apple Watch can estimate when recording certain workouts. Follow along for a look at how to use Cardio Fitness on.....»»
Research team demonstrates angular-spectrum-dependent interference
Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, refractive index changes, and surface irregulariti.....»»
Integrated photonics meets electron microscopy
Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes in electron microscopy......»»
Measurement and computer simulations of the resonant swaying of the Matterhorn
The Matterhorn appears as an immovable, massive mountain that has towered over the landscape near Zermatt for thousands of years. A study now shows that this impression is wrong. An international research team has proven that the Matterhorn is instea.....»»
Promising results from Ireland"s first large-scale measurement of methane emissions in beef cattle
The first large scale characterisation of methane emissions in Irish beef cattle conclusively shows that some beef cattle can produce up to 30% less methane emissions, on average, for the same level of productivity......»»
New aerostat realizes stable measurement of multiple atmospheric parameters
Atmospheric parameter sounding is a necessary input parameter and a reference for atmosphere and environmental protection departments to master the atmospheric conditions, conduct atmosphere and air quality forecasting and formulate corresponding eme.....»»
Two-meter COVID-19 rule is "arbitrary measurement" of safety
A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-metre rule was a number chosen from a risk 'continuum', rather than any concrete measurement of safety......»»
New breakthrough in surface-based groundwater measurement
Based on recent breakthroughs in instruments and data modeling, researchers from the Department of Geoscience and the Department of Electrical and Computer Engineering at Aarhus University have collaborated to develop an effective technology to measu.....»»

Researchers find fake news about controversial topics contributes to political polarization
It's been a year since America experienced one of its most divisive elections in decades. Although President Joe Biden has called for unity, recent data from a new measurement, the USC Polarization Index, has shown political polarization remains as b.....»»
The next step in understanding the interaction among hadrons
In a recently published article in Physical Review Letters, the ALICE collaboration has used a method called femtoscopy to study the residual interaction between two-quark and three-quark particles. Through this measurement, an interaction between th.....»»
Visualizing temperature transport: An unexpected technique for nanoscale characterization
As devices continue to shrink, new challenges in their measurement and design present themselves. For devices based on molecular junctions, in which single molecules are bound to metals or semiconductors, we have a variety of techniques to study and.....»»
First direct measurement of the overall impact of ocean eddy killing
Ocean currents, propelled by kinetic energy from the wind, are the great moderators of our climate. By transferring heat from the equator to polar regions, they help make our planet habitable......»»
Measurement techniques on display at COP26 hold key to combat climate change
Leading atmospheric scientists are measuring emissions of the most dangerous greenhouse gasses at COP26 and sharing them live online to highlight how rigorous measurement and detailed data reporting are essential in the fight against climate change......»»
"The Problem with the Big Bang Theory"
So how exactly did the universe come into existence? "A recent astronomical measurement recorded in a laboratory at the South Pole is causing scientists to revisit their theories..." writes Don Lincoln, a senior scientist at the Fermi National Accele.....»»
