A pilot study, published in the October 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, showed that breath testing could be used to discriminate between benign and malignant pulmonary nodules. The study looked at 74 patients who were under investigation for pulmonary nodules and attended a referral clinic in Colorado between March 2009 and May 2010.
Researchers from Israel and Colorado collected exhaled breath from each patient, analyzing the exhaled volatile organic compounds using gas chromatography with mass spectrometry and information from chemical nanoarrays, which have been developed by Prof. Hossam Haick and his colleagues in the Technion-Israel Institute of Technology. The patients also underwent a bronchoscopy, wedge resection and/or lobectomy, whichever was required for final diagnosis. Nodules that either regressed or remained stable over a 24-month period were considered benign.
The two techniques accurately identified that 53 pulmonary nodules were malignant and 19 were benign. Furthermore, the nanoarrays method discriminated between adenocarcinoma and squamous cell carcinoma and between early versus advanced disease.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
