*  NSA Uses Radio Waves To Spy On International Computers - Redorbit
Enid Burns for redOrbit.com - Your Universe Online. The National Security Agency (NSA) is doing more than monitoring email, cell phone calls and internet browsing. The US agency has infiltrated around 100,000 computers outside of the United States to monitor activities, and uses radio waves to retrieve data from those systems.. Radio waves are a "secret technology" used by the NSA, The New York Times reports. The agency has increasingly made use of the technology to enter and alter data on computers, even computers not connected to the Internet. This most recent information is according to NSA documents, computer experts and American officials, the Times said.. "The technology, which the agency has used since at least 2008, relies on a covert channel of radio waves that can be transmitted from tiny circuit boards and USB cards inserted surreptitiously into the computers. In some cases, they are sent to a briefcase-size relay station that intelligence agencies can set up miles away from the ...

The detectable device comprises a dipole antenna for receiving radio waves with said predetermined frequency, a diode connected in parallel to feed points of the dipole antenna for generating an electric current having a harmonic frequency of said received radio waves. A loop antenna is provided whose feed points are connected in parallel to feed points of the diode for converting the electric current having the harmonic frequency to radio waves for transmitting the radio waves at the harmonic frequency.

... AIM OF PROJECT The discussion of the concepts of radio over fiber technology and its techniques for transporting radio signals over optical fiber 1. RADIO WAVE Radio waves propagate (travel) much like surface water waves. They travel near the Earth's surface and also radiate skyward at various angles to the Earth's surface. As the radio waves travel, their energy spreads over an ever components, a crest (top portion) and a trough (bottom portion). These components travel outward from the transmitter, one after the other, at a constant velocity (speed). The distance between successive wave crests is called a wavelength Fig (1) Freq. and wavelength The electromagnetic wave spectrum is shown in Figure 2.the part usable for radio communication ranges from below 10 kHz to over 100 GHz 1.

*  IJERPH | Free Full-Text | Adaptive Response in Animals Exposed to Non-Ionizing Radiofrequency Fields: Some Underlying...
During the last few years, our research group has been investigating the phenomenon of adaptive response in animals exposed to non-ionizing radiofrequency fields. The results from several separate studies indicated a significant increase in survival, decreases in genetic damage as well as oxidative damage and, alterations in several cellular processes in mice pre-exposed to radiofrequency fields and subsequently subjected to sub-lethal or lethal doses of γ-radiation or injected with bleomycin, a radiomimetic chemical mutagen. These observations indicated the induction of adaptive response providing the animals the ability to resist subsequent damage. Similar studies conducted by independent researchers in mice and rats have supported our observation on increased survival. In this paper, we have presented a brief review of all of our own and other independent investigations on radiofrequency fields-induced adaptive response and some underlying mechanisms discussed.
*  Daily Galaxy: Radio Waves Reveal Hidden Stars at Milky Way's Center
There's a lot we don't know about the galactic center, and a lot we want to learn," says lead author Idan Ginsburg of the Harvard-Smithsonian Center for Astrophysics (CfA). "Using this technique, we think we can find stars that no one has seen before." The long path from the center of our galaxy to Earth is so choked with dust that out of every trillion photons of visible light coming our way, only one photon will reach our telescopes. Radio waves, from a different part of the electromagnetic spectrum, have lower energies and longer wavelengths. They can pass through the dust unimpeded.. On their own, stars aren't bright enough in the radio for us to detect them at such distances. However, if a star is traveling through gas faster than the speed of sound, the situation changes. Material blowing off of the star as a stellar wind can plow into the interstellar gases and create a shock wave. And through a process called synchrotron radiation, electrons accelerated by that shock wave produce ...
*  New AI algorithm monitors sleep with radio waves | MIT CSAIL
Katabi worked on the study with Matt Bianchi, chief of the Division of Sleep Medicine at MGH, and Tommi Jaakkola, the Thomas Siebel Professor of Electrical Engineering and Computer Science and a member of the Institute for Data, Systems, and Society at MIT. Mingmin Zhao, an MIT graduate student, is the paper's first author, and Shichao Yue, another MIT graduate student, is also a co-author.. The researchers will present their new sensor at the International Conference on Machine Learning on Aug. 9.. Remote sensing. Katabi and members of her group in MIT's Computer Science and Artificial Intelligence Laboratory have previously developed radio-based sensors that enable them to remotely measure vital signs and behaviors that can be indicators of health. These sensors consist of a wireless device, about the size of a laptop computer, that emits low-power radio frequency (RF) signals. As the radio waves reflect off of the body, any slight movement of the body alters the frequency of the reflected ...

*  Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth | DiscoverMagazine.com
As more people stream video to their mobile devices, wireless bandwidth is becoming an increasingly precious commodity. Data traffic increased 8,000 percent in the past four years on AT&T's network alone. In trying to avoid what the Federal Communications Commission calls a "looming spectrum crisis," telecommunications companies are lobbying the government to assign them more spectrum space in the 300- to 3,000-megahertz range, the sweet spot for wireless communication. But Italian astrophysicist Fabrizio Tamburini says a solution may lie in making better use of the frequencies already in use. In a recent paper, he demonstrated a potential way to squeeze 100 times more bandwidth out of existing frequencies.. The idea is to twist radio waves like corkscrews and create multiple subfrequencies, distinguished by their degree of twistedness. Each subchannel carries discrete data sets. "You can tune the wave with a given frequency as you normally do, but there is also a fingerprint left by the twist," ...
*  High blood pressure 'zapped' using radio waves | The Times & The Sunday Times
People with high blood pressure who do not respond to drugs may be able to have the condition treated successfully by deactivating nerves in their kidneys, new research suggests. A small study of the experimental treatment, which involves radio waves to destroy renal nerves involved in regulating hypertension, has shown that patients had their blood pressure lowered significantly. About half of all patients with hypertension are unable to reduce their blood pressure to accepted targets with drugs, diet, lifestyle interventions and other healthcare products. Scientists said that for these patients the new treatment could address the condition permanently, reducing risk of death and hypertension-related illness substantially. The treatment involves a tube pushed into a blood vessel in the groin, much like the angioplasty procedures for…. ...
