Someone explain for me again why it's OK for AirTran to provide Wi-Fi on its flights, but you can't use a cell phone that works in the same frequency range. Could it be because they can't up-charge you for the cell phone use. (Atlanta Journal-Constitution -- Metro)
Two new ESA satellites successfully lofted into orbit Nov 2, 2009
MIRAS is an interferometer that connects together 69 receivers mounted on three deployable arms to measure the temperature of the reflection of the Earth's surface in the microwave frequency range. This temperature is linked to both the actual temperature of the surface and its conductive characteristics, which are in turn linked to soil moisture for land surface and to water salinity for sea surface.

Tiny ears found on butterflys wings Oct 27, 2009
"The moth ear is a simple responding ear; it listens to a certain frequency range, and it doesn't matter what frequency it is within that range, [the moth] hears it and initiates an escape response.". As for why the morpho butterfly would need such , Lucas speculates they could help the butterflies figure out if birds are about to attack. (MSNBC -- Environment)
Smallest Nanoantennas For High-speed Data Networks Oct 26, 2009
Radio transmission by high-frequency electromagnetic light waves in the frequency range of several 100,000 gigahertz (500,000 GHz correspond to yellow light of 600 nm wavelength) requires minute antennas that are not longer than half the wavelength of light, i.e. 350 nm at the maximum (1 nm = 1 millionth of a millimeter). Controlled manufacture of such optical transmission antennas on the nanoscale so far has been very challenging worldwide, because such small structures cannot be produced... (Science Daily)

A key factor in this new science is that the Saser is the first device to emit sound waves in the terahertz frequency range; the beam of coherent acoustic waves it produces has nanometre wavelengths (billionths of a metre). Crucially the superlattice device can be used to generate, manipulate and detect these soundwaves making the Saser capable of widespread scientific and technological applications. (Science Daily)
9Boys vs. Girls: Who's Harder to Raise» May 24, 2009
Girls' hearing is more sensitive in the frequency range critical to speech discrimination, and the verbal centers in their brains develop more quickly. That means a girl is likely to respond better to discipline strategies such as praise or warnings like "Don't do that" or "Use your words." "Boys tend to be more tactile they may need to be picked up and plunked in a time-out chair," Gurian says. (Fox News)
