Lightning Strike in Africa Helps Take Pulse of Sun Nov 15, 2009
Using Very Low Frequency (VLF) wire antennas that resemble clotheslines, Prof. Price and his team monitored distant lightning strikes from a field station in Israel's Negev Desert. (Science Daily)
Yoga improves heart health Nov 10, 2009
The team explains that very low frequency (VLF) variations in the spectra are linked to the body''s internal temperature control. Low frequency peaks are associated with the sympathetic control and high frequency with parasympathetic control. (India Times, India)
Device Makes Objects Invisible In Certain Light Conditions Jul 9, 2009
ScienceDaily (July 8, 2009) A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field ... The metamaterial designed by the research group at UAB consists in an irregular network of superconductors, which give materials specific magnetic properties that can create... (Science Daily)
Exploding Volcanoes Compared With Jet Engines Apr 9, 2009
"We hypothesized that these very large natural volcanic jets were making very low frequency jet noise," said Matoza, who conducts research in the Scripps Laboratory for Atmospheric Acoustics. Using 100-meter aperture arrays of microbarometers, similar to weather barometers but sensitive to smaller changes in atmospheric pressure and low-frequency infrasonic microphones, the research team tested the hypothesis, revealing the physics of how the large-amplitude signals from eruptions are produced.

Seismic Communication in Elephants Mar 1, 2009
Like whales, elephants have large middle-ear bones that are designed to detect very low frequency sounds. They can use their unique ear structure along with other body features to detect subtle vibrations. (Suite101.com)
