Theres a lot we dont 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 arent 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 radio ...

U.S. doctor links radio waves from cell phone towers to cancer, Azheimers, senility, dementia, Parkinsons and Autism by Dr. Joseph Mercola (...)
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&Ts 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, ...
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…. ...

These waves are a form of electromagnetic radiation, or EMR. When the cell phone is turned on it locates itself by broadcasting a series of signals to the cell phone carriers closest cell phone tower. The carrier then relays that information to the nearest mobile telephone switching office. When making a call the phone sends its data to the carriers nearest tower, to the switching office and then to the switching office in the area code of the number being called. Once the connection is made the cell phones transmitter packages your voice or text data onto a second radio wave that is created for the purpose of transmitting the information. This second wave is called the Information-Carrying Radio Wave, or ICRW. When the call is received by the recipients switching office a connection is made through the nearest ...
In the second part of the thesis radio wave propagation at millimeter-wave frequencies was studied. In this work empirical characterization of scattering patterns of two built surfaces, i.e. brick and glass wall, was done. This information can be utilized in geometry-based channel modelling. In addition, we performed ray tracing simulations with the antenna structures developed in the first part of the thesis, in a conference room scenario to estimate optimum antenna configuration. To evaluate realistic conditions of radio wave propagation in indoor environments, human shadowing was also considered. It was shown that the preliminary information about radio wave propagation in the defined scenario can be obtained by performing ray tracing simulations and realistic antenna configurations can be replaced with Gaussian shaped antenna patterns before final antenna design development ...
The first primitive radio transmitters (called Hertzian oscillators) were built by German physicist Heinrich Hertz in 1887 during his pioneering investigations of radio waves. These generated radio waves by a high voltage spark between two conductors. Beginning in 1895, Guglielmo Marconi developed the first practical radio communication systems using these transmitters. Spark transmitters couldnt transmit audio (sound) and instead transmitted information by radiotelegraphy, the operator tapped on a telegraph key which turned the transmitter on and off to produce pulses of radio waves spelling out text messages in Morse code. These spark-gap transmitters were used during the first three decades of radio (1887-1917), called the wireless telegraphy or spark era. Because they generated damped waves, spark transmitters were electrically noisy. Their energy was spread over a broad band of frequencies, creating radio noise which interfered with other transmitters. Two short-lived competing ...
Vitamins E and C reduce oxidative stress in rat endometrium exposed to 900 MHz radiofrequency fields emitted from mobile phones The authors examined 900 MHz mobile phone-induced oxidative stress that promotes production of reactive oxygen species (ROS) and investigated the role of vitamins E and C, which have antioxidant properties, on endometrial tissue against possible mobile phone-induced endometrial impairment in rats. The animals were randomly grouped (eight each) as follows: 1) Control group (without stress and radiofrequency (RF) radiation), 2) sham-operated rats stayed without exposure to RF radiation (exposure device off), 3) rats exposed to 900 MHz RF radiation (RF radiation group) and 4) a 900 MHz exposed + vitamin-treated group (RF radiation + Vit group). A 900 MHz was applied to RF radiation and RF radiation + Vit group 30min/day, for 30 days using an experimental exposure device. Endometrial levels of nitric oxide (NO, an oxidant product) and malondialdehyde (MDA, an index of lipid ...
Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.. The scientists took advantage of new VLA capabilities to make a true colour radio image. This image shows the region as it would appear if human eyes were sensitive to radio waves instead of light waves. In this image, red shows where longer radio waves predominate, and blue shows where shorter radio waves predominate, following the pattern we see in visible light.. The image shows a number of strange features the astronomers think are related to an ongoing collision of galaxy clusters. The region is called Abell 2256, and is about 800 million light-years from Earth and some 4 million light-years across. The image covers an area in the sky almost as large as the Full Moon. Studied by astronomers for more than half a century with ...
SOMC surgeon Dr. Henry Childers is now providing a new approach in varicose vein treatment, using radio waves in a tube to shrink and close the diseased veins in a less invasive procedure. The tube is inserted (left), radio waves are emitted (center) to collapse the vein and the tube is removed (right).. Southern Ohio Medical Center has announced that Dr. Henry Childers is now performing a procedure that treats the underlying cause of painful varicose veins.. Dr. Childers is one of the first physicians in the area to use the VNUS ClosureFAST catheter, a tube that uses radio waves to heat, shrink and close diseased large leg veins in approximately three minutes of RF treatment.. The entire ClosureFAST procedure, from insertion of the catheter to removal, generally takes less than 20 minutes with little pain or bruising for the patient, Dr. Childers said.. Patients are very happy with this treatment approach and were very pleased to be able to bring it to our community, Dr. Childers said. ...
Now, years later, sitting in a chemo chair with an IV dripping poison into his veins, Kanzius thought back to that strange quirk of nature. If radio waves could heat metal while leaving the rest of the body untouched, then perhaps they could also kill malignant cells while leaving the healthy ones untouched. And so he began to experiment. He set up a transmitter in his garage using a couple of his wifes pie pans, stuck a metal probe into a raw hotdog, and blasted it with radio waves. The metal probe got warm; hot enough to start to cook the hotdog next to it, while the remainder stayed cold. A big idea was born. A better way. As Johns disease progressed he eventually began to receive care at M.D. Anderson in Houston, one of the worlds premier cancer centers. He explained his radio wave concept to his oncologist, who in turn introduced him to Dr. Steven Curley, who was, well, skeptical. But the more John talked about the science behind his idea, the more Dr. Curley came to believe that the ...
The authors have undertaken a comprehensive review of epidemiologic studies about the effects of radiofrequency fields (RFs) on human health in order to summarize the current state of knowledge, explain the methodologic issues that are involved, and aid in the planning of future studies
A radio base station apparatus (101) transmits and receives radio signals to and from a radio terminal apparatus (202) in a communication system in which the radio terminal apparatus (202) performs movements, whereby the radio terminal apparatus (202) can communicate with a plurality of radio base station apparatuses. The radio base station apparatus (101) comprises: a terminal power information acquiring unit (22) for acquiring terminal power information indicating the degree of change, relative to the positional change of the radio terminal apparatus (202), in the radio signal reception power of the radio terminal apparatus (202) residing within a cell formed by the local radio base station apparatus; and a movement control unit (12) for controlling the timing of the movement of the radio terminal apparatus (202) from the local radio base station apparatus to another radio base station apparatus on the basis of the terminal power information acquired by the terminal power information acquiring
Information on the exposure of individual persons to radiofrequency (RF) fields is scarce, although such data are crucial in order to develop a suitable exposure assessment method, and frame the hypothesis and design of future epidemiological studies. The main goal of this survey is to assess individual RF exposure on a population basis, while clarifying the relative contribution of different sources to the total exposure. A total of 377 randomly selected people were analyzed. Each participant was supplied with a personal exposure meter for 24-hour measurements (weekday), and kept a time-location-activity diary. Electric field strengths were recorded in 12 different RF bands every 13s. Summary statistics were calculated with the robust regression on order statistics method. Most of the time, recorded field strengths were not detectable with the exposure meter. Total field, cordless phones, WiFi-microwave, and FM transmitters stood apart with a proportion above the detection threshold of 46.6%, 17.2%, 14

Radiofrequency radiation (RFR), e.g. electromagnetic waves emitted by our cell phones and Wi-Fi, are referred to as non-ionizing. This means that in contrast to the ionizing radiation, which does induce ionization of water and biologically important macromolecules, RFR does not have a capacity for such effects. Unlike, for example X-rays, the energy of RFR is not enough to break electrons off the molecules. However, is RFR completely safe for public health? Traditionally, the....

A universal low cost radio frequency identification (RFID) tag for use with data storage discs includes an RFID chip, e.g., 2.45 GHz mu-RFID chip, coupled to a linear dipole antenna. The antenna length is reduced in length from the expected length for an optimally tuned antenna corresponding to the operating radio frequency of the RFID chip in a free space environment. The antenna is placed in the tag such as to substantially overlap disc hub area and not extend into data area. The combination of the shortened linear dipole antenna and metallization on the disc to which the tag is applied effectively form a complex antenna operational in the RFID chips frequency range. The RFID tag works on CDs and DVDs with and without substantially metallized hub areas. The RFID tag is less 0.3 mm thick and may include: ring shape, adhesive material, spacing material achieving uniform thickness, a counterbalance provision.

WASHINGTON, DC - The U.S. Food and Drug Administration, in collaboration with major implantable pacemaker and ICD manufacturers, demonstrated the effects of emissions from radio frequency identification (RFID) readers on common implantable cardiac devices. According to research published in the January edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, the observed effects may cause increasing complications as RFID use expands in the medical device field. Read full text of study ». The study, which looked at the electromagnetic interference susceptibility of 15 pacemakers and 15 ICDs caused by exposure to 13 RFID readers, concluded that low frequency RFID readers may pose the greatest risk to pacemakers and ICDs. While modern pacemakers and ICDs use filters to minimize susceptibility to higher-frequency signals, there is limited filtering of low frequency signals due to the design constraints of both pacemakers and ICDs.. The in vitro testing concluded that ...

0004] Existing RRUs have two types of structures. A first type of RRU includes a radio frequency unit, an antenna, and a radio frequency cable. The radio frequency unit includes a Common Public Radio Interface (CPRI), a Digital Analog Converter (DAC)/Analog Digital Converter (ADC), an up- and down-frequency conversion circuit, a Power Amplifier (PA), a Low Noise Amplifier (LNA), and a duplexer. The antenna includes multiple antenna oscillators, where the antenna oscillators are arranged according to a certain rule to implement spatial signal coupling. The radio frequency cable is used to connect the radio frequency unit to the antenna. Specifically, the antenna transmits a received third analog signal to the duplexer in the radio frequency unit through the radio frequency cable; the third analog signal output by the duplexer goes through the LNA, the down-frequency conversion circuit, and the ADC, and then is output to the CPRI; and the CPRI outputs the third analog signal to the BBU. ...

The typical cell phone transmitter tower is a veritable beehive of electromagnetic activity. At any given moment it can be sending and receiving the radio transmissions of 10 to 25 different phone calls. A whole row of cell phone towers can process thousands of calls simultaneously. Try to imagine what all the radio waves from all the towers just in your local area would look like, filling the air all around you. If we had the capability to see radio waves, we would be blown away. Thus cell phone towers pose a much more serious threat to living organisms than individual cell phones because they emit much more concentrated doses of radiation. When we consider that the radiation of a single cell phone can cause brain cancer in a human being at an early age, its not difficult to imagine the deadly effect that thousands of times that radiation would have on a much smaller living creature.. In fact, the gradual, slight decline in world honeybee populations observed over the course of the twentieth ...

To simulate the results from a hypervelocity impact plasma, researchers used a method called particle-in-cell simulation that allows them to model the plasma and the electromagnetic fields simultaneously. They fed the simulation details from a previously developed hydrocode -- a computational tool they used to model the fluid and solid dynamics of the impact. The researchers let the simulation evolve and calculated the radiation produced by the plasma ...
While I have always been extremely health conscious and am presently in excellent health, I did become temporarily out-of-commission (i.e. I was really sick) in 2005 with a number of at the time unexplainable symptoms. I was quite puzzled at the time because I had been eating mainly organically grown food, drinking spring water, doing Yoga every morning, and going to the gym several times a week. In other words, I was doing everything one is supposed to do to stay healthy. I was not supposed to get sick. It took me six months before discovering or even imagining the main source of the problem - which was in fact overexposure to electromagnetic - especially microwave - radiation. I was living within 200 meters of two cell phone towers at the time and within 500 meters of a 3rd one with numerous WiFi signals bleeding into my apartment from adjacent neighbors. I developed a host of symptoms, which are found in what has been misleadingly described as Chronic Fatigue Syndrome (CFS) -- but much more ...

An MRI uses magnetism and radio waves to send images of structures inside your body to a computer. In most machines, you lie on a bed that slides into and out of a tube around which theres a big doughnut-like structure that holds the magnets.. During the test, the magnets spin around you and loud sounds send radio waves through the body part being scanned. Its not a quick test-it can last anywhere from 10 minutes to more than two hours, depending on what the scan is for and how much of your body they need to examine.. During a brain MRI, your head will be immobilized in a cage-like contraption with an opening over your face so you can see and breathe.. ...
A radio frequency automatic identification system detects targets which include a plurality of radio frequency resonators. Information is attributed to the target in accordance with the radio frequency response characteristics of the target, such as the resonant frequencies of resonators present, and/or the spatial locations within the target of the resonators. Preferred resonators include thin dipoles, which may be metallizations on a plastic film substrate. Information may be attributed to a target by fabricating the target with resonators disposed at locations to encode information in accordance with a predetermined encoding system; alternatively, resonators may be randomly disposed, and a translation code applied to convert the radio frequency information to particular information in a particular format. Readers for use in the system read the radio frequency response characteristics of a target in the near field of a radiating aperture which is illuminated by a radio frequency source. Items which
Mobile phone radiation may damage cells by increasing the forces they exert on each other, scientists have said. http://news.bbc.co.uk/2/hi/health/3605203.stm. The finding could be the key to claims that mobile phones cause cancer and other health problems. Swedish physicists looked at the effect of electromagnetic radiation on red blood cells using a mathematical theory, New Scientist reported. Experts cautioned that the finding was theoretical and said there was no evidence of a danger to health. There have been suggestions that mobile phones can cause brain tumours and Alzheimers disease, but research has been inconclusive. The conventional view has been that radio waves could only damage a cell if they were energetic enough to break chemical bonds or cook tissue. But radiation given off by mobile phone handsets is too weak to do this. Bo Sernelius at Linkoping University, Sweden, looked at another possibility by modelling the properties of red blood cells. Water molecules have poles of ...

The rapid evolution of information and communication technologies (ICT) goes along with an increase in exposure to radiofrequency electromagnetic fields (RF-EMF) in our daily life. The most relevant exposure source to the brain is the use of a mobile phone close to the head. Several studies have been conducted to identify potential health effects related to RF-EMF, though results have remained inconclusive.. The research conducted by scientists at the Swiss Tropical and Public Health Institute (Swiss TPH) looked at the relationship between exposure to RF-EMF from wireless communication devices and memory performance in adolescents. The study follows up a report published in the scientific journal Environment International in 2015 with twice the sample size and more recent information on the absorption of RF-EMF in adolescent brains during different types of wireless communication device use. These are the worlds first epidemiological studies to estimate cumulative RF-EMF brain dose in ...
The spread of radiofrequency electromagnetic fields (RF-EMF) is rising and health effects are still under investigation. RF-EMF promote oxidative stress, a condition involved in cancer onset, in several acute and chronic diseases and in vascular homeostasis. Although some evidences are still controversial, the WHO IARC classified RF-EMF as possible carcinogenic to humans, and more recent studies suggested reproductive, metabolic and neurologic effects of RF-EMF, which are also able to alter bacterial antibiotic resistance. In this evolving scenario, although the biological effects of 5G communication systems are very scarcely investigated, an international action plan for the development of 5G networks has started, with a forthcoming increment in devices and density of small cells, and with the future use of millimeter waves (MMW). Preliminary observations showed that MMW increase skin temperature, alter gene expression, promote cellular proliferation and synthesis of proteins linked with ...

Mobile phone use is not associated with the risk of melanoma of the eye, researchers report in the January 13 online issue of the Journal of the National Cancer Institute.. Although there is no direct link between exposure to radio waves and DNA damage, which can lead to cancer, studies have examined the possibility of an association between mobile phone use and melanoma of the eye, also called uveal melanoma.. In the current study, Andreas Stang, M.D., of the Martin-Luther-University of Halle-Wittenberg in Germany, and colleagues examined the association between phone use and risk of uveal melanoma in 459 patients and 1,194 control subjects. Control subjects were drawn from the general population, from ophthalmology clinics, and from siblings of the patients. The investigators grouped study participants according to amount of time spent on the phone, as never users, sporadic users and regular users.. There was no statistically significant association between mobile phone use of up to about 10 ...
Magnetic resonance imaging (MRI) is a diagnostic study that makes pictures of organs of the body using magnetic field and radio frequency pulses that can not be felt. Dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI) uses faster imaging and contrast material (a substance used to make specific organs, blood vessels, or tumors easier to see) that is given by vein. Diffusion weighted magnetic resonance imaging (DW-MRI) allows to measure the motion of water around the cells in the tumor. Proton magnetic resonance spectroscopy (MRS) obtains chemical information from the tumor. During MRS, signals are detected from the chemicals (spectroscopy) naturally present in your tumor using radio waves. DCE-MRI, DW-MRI and MRS give extra information which is not available with the regular MRI. The regular MRI only shows pictures of the tumor while the DCE-MRI also gives information about the blood vessels of the tumor. DW-MRI provides information related to the state of the tumor tissue with ...
Extragalactic source of radio-wave flashes resides in a powerfully magnetized astrophysical region New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the sources environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power. The findings by an international team of astronomers, including Victoria Kaspi and Shriharsh Tendulkar of McGill University, appear in the January 11 edition of Nature and are highlighted on the cover of the journal. A year ago, the astronomers pinpointed the location of the enigmatic fast radio burst (FRB) source named FRB 121102 and reported that it lies in a star-forming region of a dwarf galaxy more than 3 billion light years from Earth. The vast distance to the source implies that it releases an enormous amount of energy in each burst -- roughly as much energy in a single millisecond as the Sun releases in an entire day. Now, using data from the Arecibo
I think there are lots of people who would love to have the funding to put a radio telescope in orbit or on the dark side of the moon. But its unlikely anyone will fund the project. We are Lucky to have telescopes like Hubble, Splitzer and Fermi. Radio telescopes need to be massive, they need a massive collecting area. As Tullio said, its easier to build them on the ground because radio waves are not blocked by the earths atmosphere ...

If you search hard enough, youll be able to locate legitimate scientific studies that indicate there may be a cancer risk from the radio wave radiation thats emitted from your cell phone. On the other hand, youll be able to find just as many studies that prove theres no danger from the levels of radiation coming from your phone. What do you believe? Unfortunately, the current state of cell phone radiation research is similar to the early days of tobacco research. It wasnt until 1999 when the U.S. Department of Justice finally filed a racketeering lawsuit against the major tobacco companies for engaging in a 50 year scheme to counteract any scientific evidence that showed that cigarettes are harmful to a persons health. Is the potential cell phone cancer link the same sort of scenario? Are cell phone companies funding and promoting research that proves no link from cell phone radio radiation in an effort to discredit those studies that are uncovering problems? ...

And for all the civil servants - employed by various governmental authorities - to actively lure their own government and parliament must be regarded as very serious. I believe it is called high treason to engage in such an act, or…? I, as a scientist, am not here to promote convenience or economic growth, but only to serve and protect human health, as well as to directly protect other animals, plants, and bacteria. These aims must be my only target, not to ensure consumers nor parliaments there is no cause for alarm which would be a blatant lie.. ***. Based on earlier conclusions, the World Health Organization (WHO) in Geneva already in 2001/2002 classified powerfrequency magnetic fields as possibly carcinogenic for childhood leukemia (Class 2B), and, by May 31, 2011, radiofrequency electromagnetic fields were also classified as possibly carcinogenic for certain brain tumours (Class 2B).. In the same year, the Council of Europe said Ban mobile phones and wireless networks in schools, ...
The risks to public health of NIR, whether in the form of UV light, radio waves from wireless devices, or electric and magnetic fields associated with electrical power systems, is currently a cause of great concern among members of the public and lawmakers. But in order to separate established science from speculation and make informed decisions about how to mitigate the risks of NIR and allocate precious resources, policymakers, manufacturers, and individuals need a comprehensive source of up-to-date information based on the current scientific evidence. Written by a team of experts in their fields, this book is that source. Among other things, it: Summarizes scientific findings on the safety of different forms of NIR and the rationale behind current standards Describes devices for monitoring NIR along with the established and potential hazards of each form Explores proper protections against UV light and lasers, RF radiation, ELF fields and other forms of NIR Discusses how to avoid injuries ...
Julie,. Heres a site with some measurement equipment (I have no affiliation or make no claims of utility or value). From their meter page (http://www.lessemf.com/emf-mete.html) you can click through to tools to measure magnetic fields (gaussmeters) and electric fields. Those are typically generated by 60 Hertz A/C appliances but can also include higher frequencies (e.g. TV sets before flat panels). Changes in electric fields results in magnetic fields and vice versa. But when static or low frequency, those fields are generally short distance phenomena and can be fairly easily shielded against.. When either an electric or magnetic field is modulated (turned on and off at a particular frequency), it and its associated field propagates through space as an electromagnetic wave or electromagnetic radiation. Electromagnetic radiation spans radio waves to infrared heat sources to lights to ultraviolet from lights and the sun to ionizing radiation (i.e. X-rays). Those waves can travel great distances ...
Provided is an RED eyelet performing non-contact identification function. The RFID eyelet includes an eyelet washer and eyelet base composed of nonconductive material, and an RED module is interposed between the eyelet washer and eyelet base. The RFID eyelet contains the RFID module in nonconductive material, thereby performing smooth electromagnetic wave communication without disturbance, and the eyelet base is simply coupled. with the eyelet washer by using a slanted projection formed in the eyelet base and a locker formed in the eyelet washer. Also, the RED module can be easily installed by using an internal flange or external flange formed in the inside of the eyelet base or eyelet washer, thereby having a merit of mass production.
An integrated passive wireless chip diagnostic sensor system is described that can be interrogated remotely with a wireless device such as a modified cell phone incorporating multi-protocol RFID read
In recent years, the zebrafish, Danio rerio, has become a widely used model for vertebrate genetics, developmental biology and toxicology studies (Spitsbergen and Kent, 2003). Several thousand mutants and transgenic lines have been produced and laboratories commonly rear several of these lines simultaneously. In most cases, these fish cannot be distinguished by eye, meaning that fish from different lines must be kept in different tanks. From a practical viewpoint, this requires laboratories to manage large rearing facilities housing several hundred tanks, which is both costly and time consuming in terms of husbandry (Sire et al., 2000). Moreover, rearing problems may occur in zebrafish if populations are small because this interferes with shoaling behaviour, especially as shoaling in this species has been shown to increase significantly with age (Buske and Gerlai, 2011). Furthermore, because small fish such as zebrafish (≤30 mm standard length, SL) are not aggressive and do not fight when kept ...
