Elderly lung cancer patients tolerate combined chemotherapy and radiotherapy with no higher risk of death than younger patients, according to a new study appearing in the June 1, 2005 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society
Lung cancer remains the leading cause of cancer deaths in the U.S., with half of those diagnosed at age 70 years or older. About 20 percent of patients with lung cancer will have small cell lung cancer (SCLC). In the past, SCLC progressed rapidly despite initial chemotherapy sensitivity and few patients survive three years.
New treatment modalities have provided encouraging results. Studies have found chemotherapy combined with radiotherapy improves survival over chemotherapy alone. Since that finding, researchers have developed new protocols for combined modality treatment to improve survival. Investigators led by Steven E. Schild, M.D. of the Mayo Clinic and the North Central Cancer Treatment Group conducted a clinical trial using two different approaches to combined therapies. Using data from this trial, they sought to evaluate the role of age in therapy tolerance, disease control, and survival following combined modality therapy.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
