Almost half of lung cancers detected by a chest x-ray were early-stage cancers, according to baseline results of a large, randomized clinical trial that is testing the efficacy of a chest x-ray as a screening test for lung cancer. The study results are published in the December 21 issue of the Journal of the National Cancer Institute.
Lung cancer causes one million deaths worldwide every year. When patients begin to experience symptoms of lung cancer, the cancers are often advanced and treatment is rarely successful; 90% of newly diagnosed lung cancer patients die within 2 years of diagnosis.
In 1992, The National Cancer Institute launched the still-ongoing Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial to evaluate screening tests for each of the four cancers. The PLCO Cancer Screening Trial is the largest trial ever conducted in the United States. The 155,000 men and women enrolled in the study were asked about past and present smoking habits, medical history of themselves and their families, and personal characteristics. For the lung cancer portion of the trial, participants were randomly assigned to a control group or to a screening group that received a single-view, posterior–anterior chest x-ray.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
