Unique Greenhouse Gas Meter Developed
2014-06-18 03:59:50

Moscow Institute of Physics and Technology MIPT’s Laboratory for the Spectroscopy of Planetary Atmospheres has come up with a high-resolution meter to gauge the concentration of gases in the atmosphere with unparalleled precision. The infrared spectrum radiometer is described in an article recently published in the journal Optics Express. The paper, authored by Alexander Rodin, Artem Klimchuk, Alexander Nadezhdinsky, Dmitry Churbanov and Maxim Spiridonov, says that the new spectrum...

World's Most Extreme Hearing Animal Discovered By Researchers
2013-05-08 14:45:58

University of Strathclyde Researchers at the University of Strathclyde have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300kHz — the highest recorded frequency sensitivity of any animal in the natural world. Humans are only capable of hearing sounds of 20kHz maximum, dropping to around 12-15kHz as we age, and even dolphins, known exponents of ultrasound, can't compete as their limitations are around 160kHz. The research, conducted at...

Environmental vibrations induced by urban railway traffic are mainly generated from uneven wheel—rail contact in the short wavelength range, according to a study in the 4th issue of SCIENCE CHINA Technological Sciences, 2012. The introduction of urban railways is one of the most effective ways to deal with traffic problems in large cities. However, in the vicinity of railways, day-by-day vibrations from trains may cause discomfort to people, the malfunctioning of sensitive equipment,...

Move Over GHz, Terahertz Bandwidth Could Make Smartphones 1,000 Times Faster
2012-03-09 04:47:31

Peter Suciu for RedOrbit.com While those Verizon and AT&T commercials may claim that the respective carrier has the “fastest” network for mobile phones, new communications technology could make today´s 3G and 4G networks look as antiquated as the telegram. The whole gigahertz frequency could be made obsolete as a team of researchers at the University of Pittsburgh look to develop a terahertz frequency that could provide a means of transmitting data thousands of...

'Star Comb' Joins Quest For Earth-like Planets
2012-03-08 04:03:29

If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it. Such a comb–a tool for precisely measuring frequencies, or colors, of light–has for the first time been used to calibrate measurements of starlight from stars other than the Sun. The good results suggest combs will eventually fulfill their potential to boost the search for Earth-like planets to a new level. As described in Optics...

Researchers Bend Radio Waves Into Pasta Shapes
2012-03-02 13:36:50

Researchers have solved the problem of radio congestion by twisting radio waves into the shape of fusilli pasta. Scientists reported in the Institute of Physics and German Physical Society's New Journal of Physics that this feat allows for a potentially infinite number of channels to be broadcast and received. A wave is able to twist a certain number of times in either a clockwise or anti-clockwise direction, allowing for several configurations. "In a three-dimensional perspective,...

By Katie Neith, Caltech While many hotel rooms, recording studios, and even some homes are built with materials to help absorb or reflect sound, mechanisms to truly control the direction of sound waves are still in their infancy. However, researchers at the California Institute of Technology (Caltech) have now created the first tunable acoustic diode-a device that allows acoustic information to travel only in one direction, at controllable frequencies. The mechanism they developed is outlined...

The sun is a very noisy place, generating an inferred multi-frequency song comparable to cathedral bells To most of us, the sun seems to dangle in space silently without making so much as a peep. Nevertheless, "the sun is a very noisy place," said Scott McIntosh of the National Science Foundation (NSF)-supported National Center for Atmospheric Research. What does the sun sound like? As best as we can tell, the sun sounds like a low hum punctuated by frequent rhythmic, bass-y thumps. How does...

Boston University team makes strides in detecting and controlling terahertz radiation Devices that can mimic Superman's X-ray vision and see through clothing, walls or human flesh are the stuff of comic book fantasy, but a group of scientists at Boston University (BU) has taken a step toward making such futuristic devices a reality. The researchers will present their device at the Conference on Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference (CLEO/QELS: 2010), which...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
