New imaging parameters rein in incremental radiation dose from potentially life-saving CT-guided biopsy of lung nodules to reduce patients' overall exposure New guidelines for CT-guided biopsies of lung nodules significantly reduce radiation exposure allowing individuals the benefit of the procedure, which may cut down on overall lung cancer deaths. This research is being presented at the Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif. "The...
Radioactive medicine being tracked through rivers A University of Delaware oceanographer has stumbled upon an unusual aid for studying local waterways: radioactive iodine. Trace amounts of the contaminant, which is used in medical treatments, are entering waterways via wastewater treatment systems and providing a new way to track where and how substances travel through rivers to the ocean. "This is a really interesting convergence of medicine, public health and environmental science,"...
Plants have long been known as the lungs of the earth, but a new finding has found they may also play a role in electrifying the atmosphere. Scientists have long-suspected an association between trees and electricity but researchers from Queensland University of Technology (QUT) think they may have finally discovered the link. Dr Rohan Jayaratne and Dr Xuan Ling from QUT's International Laboratory for Air Quality and Health (ILAQH), led by Professor Lidia Morawska, ran experiments in...
Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon's surface from galactic cosmic ray (GCR) bombardment that over time causes chemical changes in water ice and can create complex carbon chains similar to those that help form the foundations of biological structures. In addition, the radiation process causes the lunar soil, or regolith, to darken over time, which is important in understanding the...

LITTLETON, Mass., March 14, 2012 /PRNewswire/ -- Mevion Medical Systems, a radiation therapy company dedicated to advancing the treatment of cancer, has announced today that it has received CE Marking certification for the MEVION S250 Proton Therapy System. This important commercial milestone indicates that Mevion has completed its development in compliance with the European Union's Medical Device Directive. The CE Marking allows the MEVION S250 to be marketed, sold, and installed in...
Offsite Planning to Reduce the Public's Exposure to Radiation BALTIMORE, March 7, 2012 /PRNewswire-USNewswire/ -- In a report released today, researchers at the Center for Biosecurity of UPMC assess offsite policies and plans that can be put in place to reduce the exposure of the public to radiation in the event of a nuclear power plant accident. Even amidst the devastation following the earthquake and tsunami in Japan last year that killed more than 20,000 people, it was the...
The number of cancer survivors in the United States has tripled since 1971 and yet gains in survival have come at the price of second malignancies and cardiovascular disease, according to a long-awaited report by a national scientific committee chaired by Lois B. Travis, M.D., Sc.D., of the University of Rochester Medical Center. The Journal of the National Cancer Institute is publishing a detailed summary online March 6, 2012, and will publish the summary in hard copy on March 13. The...
[ Watch the Video ] With a pair of bug-eyes swiveling on a stalk nearly 8 feet off the ground, the 6-wheeled, 1800-lb Mars rover Curiosity doesn’t look much like a human being. Yet, right now, the mini-Cooper-sized rover is playing the role of stunt double for NASA astronauts. “Curiosity is riding to Mars in the belly of a spacecraft, where an astronaut would be,” explains Don Hassler of the Southwest Research Institute in Boulder, Colorado. “This means the rover experiences...
PRINCETON, N.J., Feb. 21, 2012 /PRNewswire/ -- Soligenix, Inc. (OTCBB: SNGXD) (Soligenix or the Company), a development stage biopharmaceutical company, announced today further promising preliminary results from its continuing preclinical study of SGX202 (oral beclomethasone dipropionate or BDP) in a canine gastrointestinal acute radiation syndrome (GI ARS) model. The new study results indicate that dogs treated with SGX202 starting 24 hours after exposure to lethal doses of total...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...
The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...
Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...
Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
