Researchers detected the presence of a strong double resonance frequency at 70Hz and 114Hz inside a 5,000-years-old mortuary temple on the Mediterranean island of Malta. The Ħal Saflieni Hypogeum is an underground complex created in the Neolithic (New Stone Age) period as a depository for bones and a shrine for ritual use. A chamber known as "The Oracle Room" has a fabled reputation for exceptional sound behavior.
During testing, a deep male voice tuned to these frequencies stimulated a resonance phenomenon throughout the hypogeum, creating bone-chilling effects. It was reported that sounds echoed for up to 8 seconds. Archaeologist Fernando Coimbra said that he felt the sound crossing his body at high speed, leaving a sensation of relaxation. When it was repeated, the sensation returned and he also had the illusion that the sound was reflected from his body to the ancient red ochre paintings on the walls. One can only imagine the experience in antiquity: standing in what must have been somewhat odorous dark and listening to ritual chant while low light flickered over the bones of one’s departed loved ones.

Sound in a Basso/Baritone range of 70 – 130 hz vibrates in a certain way as a natural phenomenon of the environment in the Hypogeum, as it does in Newgrange passage tomb, megalithic cairns and any stone cavity of the right dimensions. At these resonance frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy. Echoes bounce off the hard surfaces and compound before they fade. Laboratory testing indicates that exposure to these particular resonant frequencies can have a physical effect on human brain activity.
What is astounding is that five thousand years ago the builders exploited the phenomenon, intentionally using architectural techniques to boost these "super-acoustics". Glenn Kreisberg, a radio frequency spectrum engineer who was with the research group, observed that in the Hypogeum, "The Oracle Chamber ceiling, especially near its entrance from the outer area, and the elongated inner chamber itself, appears to be intentionally carved into the form of a wave guide."
The same people who created Ħal Saflieni also engineered a complete solar calendar with solstice and equinox sunrise alignments that still function today in one of their above-ground megalithic structures. There is no question that a sophisticated school of architectural, astronomic and audiologic knowledge was already in place a thousand years before the Egyptians started building pyramids.

…This technology uses a “covert channel of radio waves” that can be transmitted from circuit boards and USB cards planted in computers, the report said, citing leaked NSA documents and US officials.
Filling in some more details of the NSA surveillance programmes revealed by whistleblower Edward Snowden in June 2013, the report said the transceivers must be physically inserted by a spy, a manufacturer or an unwitting user.
Once in place, the transceivers communicate with a briefcase-sized NSA field station, or hidden relay station, up to eight miles away.
The field station in turn communicates back to the NSA, and can also transmit malware to the target computer, including the kind used in attacks against Iran’s nuclear facilities.
“What’s new here is the scale and the sophistication of the intelligence agency’s ability to get into computers and networks to which no one has ever had access before,” James Andrew Lewis, a cyber security expert at the Center for Strategic and International Studies in Washington, told the NYT.
“Some of these capabilities have been around for a while, but the combination of learning how to penetrate systems to insert software and learning how to do that using radio frequencies has given the US a window it’s never had before.”
The paper lists Chinese and Russian military, Mexican drug cartels, and trade institutions in the European Union, Saudi Arabia, India and Pakistan as targets of the surveillance programme code-named Quantum.

ScienceDirect.com – Brain Stimulation – Stimulation of the brain with radiofrequency electromagnetic field pulses affects sleep-dependent performance improvement
Sleep-dependent performance improvements seem to be closely related to sleep spindles (12–15 Hz) and sleep slow-wave activity (SWA, 0.75–4.5 Hz). Pulse-modulated radiofrequency electromagnetic fields (RF EMF, carrier frequency 900 MHz) are capable to modulate these electroencephalographic (EEG) characteristics of sleep.
The aim of our study was to explore possible mechanisms how RF EMF affect cortical activity during sleep and to test whether such effects on cortical activity during sleep interact with sleep-dependent performance changes.
Sixteen male subjects underwent 2 experimental nights, one of them with all-night 0.25–0.8 Hz pulsed RF EMF exposure. All-night EEG was recorded. To investigate RF EMF induced changes in overnight performance improvement, subjects were trained for both nights on a motor task in the evening and the morning.
We obtained good sleep quality in all subjects under both conditions (mean sleep efficiency > 90%). After pulsed RF EMF we found increased SWA during exposure to pulse-modulated RF EMF compared to sham exposure (P < 0.05) toward the end of the sleep period. Spindle activity was not affected. Moreover, subjects showed an increased RF EMF burst-related response in the SWA range, indicated by an increase in event-related EEG spectral power and phase changes in the SWA range. Notably, during exposure, sleep-dependent performance improvement in the motor sequence task was reduced compared to the sham condition (−20.1%, P = 0.03).
The changes in the time course of SWA during the exposure night may reflect an interaction of RF EMF with the renormalization of cortical excitability during sleep, with a negative impact on sleep-dependent performance improvement
